Some folks have been having trouble posting to the thread "OT: Time
Zones and Medicine," which I admit is kind of long by now and isn't even
about time zones or medicine any more. My idea for solving this (and I
am unanimous in that!) is starting this new OT thread, of which this is
the root. Any replies I'd be making to that thread will be posted as
replies to this message, and I'm hoping everyone participating there
will sort of drift over to here.

I also hope I'm not opening a whole can of worms by doing this. :-)

I read somewhere that it wasn't until the 1920s that a doctor had a
better than 50% chance of helping a patient.
Around 1981 I heard an MD, head of an in-house clinic at one of the USG
agencies, present a serious argument that doctors assuredly did more
harm than good until mid-20th Century.
Similar to what I read, except for a few decades' difference. :-)
He held that introduction of antibiotics, specifically Penicillin G,
marked the turning point. (I remain unconvinced that the corner has been
turned. Doctors can do [and sometimes do] some wonderful things, but the
Hippocratic Oath "First of all, do no harm," long has been constantly
violated, out of ignorance if not simply because it is more profitable
and easier to do things that will placate patients than to actually do
things to improve their health.)
Have you read the book "A Surgeon's World"? It's from the 1970s, but is
an honest look at that from the viewpoint of a practicing surgeon. What
do you do when your patient has numerous complaints but nothing really
wrong, for example.
And before anyone decides to disagree, try one simple test.
Ask yourself if health care provided in the United States is worth 15
percent of total goods and services produced in the country. One dollar
of ever seven expended in the U.S. is spent on "health care," and it
looks to me like the economic damage outweighs the good it does.
What do you feel it should be spent on?

I'm not going to get into a debate about health care systems, or things
called that, because I'm in an uncommon situation and so I don't have
the viewpoint of the "average American."

What do you feel it should be spent on?
Easy answer: Let people keep their money instead of being forced
(or encouraged if you prefer that term) to spend it like a
drunken sailor in search of a good time. They will think up
things to spend it on, that will suit them better than my
preferences would.

If you really want health care, you find real quick that there
are many choices available on the strip, but differences among
them pale in comparison to the similarities in how the deck is
stacked against you. What you will pay will be determined
basically by how much you have that can be stripped from you by
means fair or otherwise. And the results may vary from glorious
tales of serendipity to horror stories of what you found you had
actually purchased. (Nope. That was not given you. You paid
for it. etc.)

If someone has earned the money and wants to spend it in that
fashion, I have no real complaint. No skin off my nose. But I
do not like money I have earned being taken from me to pay what I
consider egregious amounts for others. Illustration: Last time
I saw the numbers, quadruple by-pass heart surgery cost about
$125,000, and made life somewhat more comfortable for the one
operated on (and financially more comfortable for the surgeon et
al!), but did nothing to improve the 5-year survival rate or
physical abilities post-operation.

And I am not real happy that the "big spenders" are using tax
money and governmental pressures (e.g. regulations on
availability and terms of health care) that drive up market
prices to levels I see no justification for.

No cheers.

What were the hardware requirements of Linux 1.0, and how do they
compare to the requirements for some of today's bulkier distros?
Oh, that I don't know... However, I remember PTB once saying he ran a
complete GNU/Linux with X in 4 MB of RAM back at the time. However,
one must keep in mind that most of the requirements for heavier
hardware have come from the increase in functionality and eyecandy of
the window managers and desktops. And unlike with Windows, the newest
versions of GNU/Linux actually _are_ more powerful than the earlier
versions. ;-)
But RAM required /is/ increasing, and many distros /are/ adding all the
eyecandy too. Last year I acquired a 486 system with 40MB RAM, and
wasn't able to get any distro to work on it. Even the "minimal" ones
wanted at least 64MB RAM.
There has to be SOMEbody out there who makes a
black USB keyboard. Don't they have USB-to-PS/2 converters for
keyboard, too, so you could connect a black PS/2 keyboard to it?
Well, of course, a USB-2-PS/2 connector is an option, but it's all
beside the point. I mean: they sell them in black or white with a PS/2
connector - I have one like that - but apparently the USB version is
only sold in white, even though the manufacturer does produce them in
black as well. And the white is actually listed as "grey" on the
website, but I have seen them, and they really /are/ white.
This is not just any keyboard either, mind you. I'm very specific about
the type: it has to be a Cherry G81-3000.
As I see it, your options are:

1) If the manufacturer is producing them in black, they must be being
sold SOMEwhere, so find out where that is. Have you tried contacting
the manufacturer?

2) Get the black PS/2 model and a PS/2-USB converter.

3) Get the white model and paint it or something. (Not really a
practical option.)

4) Settle for a white keyboard. (Understandably not desirable.)

5) Search for a different keyboard that's black, USB, and "close enough"
to the model you want in keyboard feel, or whatever's important to you.

I can understand your problem, but I don't see what I can do about it.


BTW, a quick Google search pulled up
http://www.possavings.com/Cherry_G81_3000_Full_Size_Keyboard_p/g81-3000lunus-2.htm
-- is that what you're looking for?

No, I haven't, but there is some confusion there as only the German site

If all else fails, that is an option, yes.

Well, I'll already have the white model since I ordered a *grey* one -
which is the name they give to white these days; go figure - and the
hardware supplier said that he can't sell that one to anyone anymore
and asked me whether I would then still buy it, at a discount. So I
said "yes", thinking that if these keyboards are indeed going to be
phased out, it'd be good to have a spare.

Painting it on the other hand is not really an option. ;-)

I'm afraid those are the only ones I prefer. Well, that or a Unicomp,

I require a Belgian layout, which isn't listed on the site.

First of all, the weight and size. Most keyboards these days are just
little pieces of plastic with almost no weight, and they quickly move
out of their position if you accidentally bump into them with
something. I hate that. The Cherry G80-3000 and G81-3000 models are
quite large and fairly heavy - I think they have a copper plate in the
base.

Secondly there's the feel. The G80-3000 has the old-school mechanical
switches while the G81-3000 uses membrane switches, but they are of
excellent build quality. They don't feel as buttery as most other
keyboards. They also don't have all those "multimedia" or "shorcut"
keys you find on most other keyboards these days. (They do have the
Win-keys though, but then again, those are useful in a GUI like KDE.)

If you've paid with a credit card, even a secured credit card (as
opposed to a debit card), you can always dispute the charge(s).

My experience has been those transactions in other currencies are
often converted at extortionist rates. One card user agreement I saw
recently made a change the wording relating to conversions - it used
to be the higher of the bank interchange or official exchange rate on
the day the charge was posted, and now it's 3% above the highest of
those rates in effect on any of the previous three business days to
the posting date.

Read the fine print carefully - some of them have fees up to ten
percent added on to the charge. The pre-paid Visa cards you see in
stores are an example of this ripoff. The 25 Quatloos gift card you
give as a Christmas gift to your bookie is only worth 22.5 Quatloos
to him/her.

A "secured credit card" is handled like any other credit card -- I can

it's a secured card.

My "regular" bank gave me a debit card, but (as you said) it lacks many
of the protections (although the bank provides a few of them). That by
itself wouldn't be too helpful, except it can also be rung up as a
credit card, which saves me the transaction fee. I only use it for
in-person transactions, mainly locally.

One time I intentionally did use it as a debit card was when I was in
California (i.e. far from home, where there were no branches of my bank)
and low on cash. Instead of paying the $2-3 fee for using another
bank's ATM, I used it at a supermarket to buy groceries and asked for
additional cash back, which only cost me the (roughly) $1 debit card
usage fee.

Before I had my secured credit card, I did that a few times, and I think
it was a fixed fee. The banks also profit from the cards that are lost
or never used, or never used up completely. And if you do use one, you
end up with some piddling amount left that's barely worth the trouble.

I don't know if your PBS radio carries "Performance Today", but one of
the weekly features is a "Piano Puzzler" - where Bruce Adolphe (some
form of current classical composer I guess) takes a piece of music
(which can be _anything_ from old classics to children's songs, show
tunes - even something by the Beatles) and plays it in the style as
if written by some other composer - think "Norwegian Wood" as if
written by Bach, or "The Great Gate of Kiev" in the style of Grieg -
and a listener is invited to identify the music and the composer being
imitated. I usually get over three quarters of the music, but have a
horrible success rate identifying the composer.
I haven't heard it, but -- maybe he's not all that good at writing in
the styles of other composers, which can be /quite/ difficult to do
recognizably. One of my music history professors specifically praised
Peter Schickele's attempts at that. One of my favorites is "And the
Same to You" from "Beyond the Fringe", in a very recognizable style.

In 1911 in France there was a "Concert sans noms d'auteurs" (concert
without names of the authors), and although all the works were from
living French composers, almost nobody recognized the composer of
"Valses Nobles et Sentimentales" as Maurice Ravel.

Gotcha - I had forgotten about that mode. Several years ago, I had a

used for on-line stuff, but the issuing bank got a case of the 'jack
up the fees' virus, and I closed it. It did have a credit option,
and the interest rates were quite high as usual. It also had an

Depends on how hungry your bank is - our "main" checking account
bank has fees for using other ATM systems or for using more than 5
(I think) transactions a month on their own ATMs. At one time, banks
were encouraging use of ATMs in place of regular teller services. Now
it seems they're just interested in milking the maximum they can out
of the customers, while paying virtually nothing in the way of
interest on deposits. We also have two other banks that don't charge
for ATM use, and will reimburse any fees charged by other banks (up
to a monthly limit).

The usual answer is to shop around. The charges differ by card
issuer, and there may be other options. It also depends on the
amount of the transaction. A US$25 fixed fee on a $5 purchase is
going to feel just as bad a a 5% fee on a $500 purchase. The larger
banks that make exchange transactions as part of their normal
business may also offer a better rate. I dislike Chase and BofA,
but have used them in preference to the 4th National Bank of Podunk
or a credit union for this.

I haven't had the need in a while, but have used bank transfers in

rate. Lately I've seen rate cards from several banks switching to
fixed fees rather than percentages. By the way, have you noticed

Worse. A $25 fee on a $5 purchase means over 80% of the cost is the
fee. 5% on a $500 purchase is under 5% of the total cost.

A few years back, I was given IIRC 300 Finnish Markka in cash (pre-EU).
It took me a half-dozen referrals from one bank to another to finally
get to one that handled cash exchanges, which was BofA (yes they are
around here now). I think they had a fixed fee of $10, which was a
significant chunk considering 300 FM was worth about US $60, but I
figured I'd better get it exchanged before the FM gets completely
replaced by the Euro.

Sounds about right, although it varies merchant to merchant. In theory
they also make money on any positive balance you may keep though at

I just went through the statement on our "main" bank. Those checks are
free, but the interest paid on the checking is a whopping 0.08 percent.
The two other banks (yes, credit unions) are paying more, but the
checks are $5 per box. I had a look at one of their rate cards a bit
before Christmas and wasn't impressed, but it's better across the
board compared to the bank.

A few years back, I was given IIRC 300 Finnish Markka in cash (pre-EU).
It took me a half-dozen referrals from one bank to another to finally
get to one that handled cash exchanges, which was BofA
That's the big problem. Many banks will do the exchange through what
they call corresponding banks, but the fees are about twice what you
can get from a bank that has an international presence.

I think they had a fixed fee of $10, which was a significant chunk
considering 300 FM was worth about US $60, but I figured I'd better
get it exchanged before the FM gets completely replaced by the Euro.

I hate to tell you, but that's pretty competitive today. Then you run
into the question of which exchange rate they're going to hit you
with. That can amount to as much as a 5% difference.
Post by Adam
By the way, have you noticed what they're charging for
international traveler's checks now?
There's two kinds - the first (and more usable) are in local currency
denominations, while the second are dollar denominations but payable
at the local exchange rate. The first are sold at a disadvantageous
(to you) exchange rate, and they throw a transfer fee ($10-$40
depending on the bank). There may be a redemption charge imposed by
the place you're trying to spend them at. The second kind cost you
a few percent to buy (3-6 is what I've seen), but the redemption
charges "over there" can be quite stiff and the exchange rates are
often as bad or worse than you buying the first kind unless you
have an "American" bank over there where you can cash them. $DEITY
help you if you're going out into the sticks.

No, the only time I got out of North America was in 1976.
It's a lot worse now. My sister was planning to revisiting the UK
this summer (she spent three weeks in several countries in .eu in
1990), but she's wailing about the costs she's seeing. The company
sent me to Europe in 2006 and the Far East in 2008. It was two weeks
each on their nickel, but WOW. I made very few purchases on my own.
I suspect those were the last overseas trips I'll do for the company.

Is Schwann still being published? I used to buy it occasionally
back in the LP era.
No, it went under around 2000. The English 'Gramophone' magazine also
used to publish catalogs, but I think the last one I found was in 1992
at a place called Classical Wax just down the hill from the houses
made of ticky-tacky in Serramonte. Of course that's a bit of an
advantage about classical music - even the older catalogs are still
useful. ;-)

The card plan I was referring to wanted you to keep "a" positive
balance at all times. If they really wanted to, they _could_ (though
rarely did) refuse a charge if it would have resulted in a negative
balance. Basically, you put in an initial deposit, then paid the
monthly purchases at the billing time. The bank that offered this
program (~3-4 years ago) would pay interest based on the lowest
monthly balance, and I understood a competitor paid based on the
daily average basis. In both cases, the interest rate was close
enough to zero as to need a magnifying glass to see, but they also
had no monthly/annual fee. If you went to a negative balance, you
owed them one percent per day (or some other equally punitive rate)
interest. Keeping a positive balance wasn't all that hard, and I'm
sure they were making money off the deal. But then they decided
they needed higher income, and added an annual fee, and a fee for a
cash-back situation. I decided it wasn't worth it, and bailed.

That's basically what killed off Schwann. Who would buy the dead-tree
catalog at two-three bucks a pop when you can find the info on-line?
The record companies saw little return on their advertising, and the
record stores saw little sales of the catalogs or of records based on
something in the catalog. Gramaphone on the other hand was a bit
more specialized, but still ran into the same economic reality.

CD of the Goldberg Variations - a re-issue of the 1982 LPs. Cost was
one dollar, and the darn thing was still sealed. Who am I to complain

That's what I thought too, and that's how my cards work (which is a good
thing, otherwise I'd be even more confused). The bank with my checking
account gave me a debit card. It can be rung up as a credit card
instead, which saves me a small fee, but either way the money comes
right out of my account (well, usually a day or two later) and is /not/
protected by the laws applying to credit cards.

My "secured" credit card, through another institution, /is/ credit (as I
understand it). I use it, and get a bill at the end of the month for my
purchases, where I can pay the entire balance or just the specified
minimum. And purchases made with it are covered by the laws for credit
cards.

That card plan didn't encourage you to have a negative balance, being
closer to a pre-paid credit card. If I recall correctly, they also
offered a "conventional" credit card, where they did encourage you to
owe them money, and the interest rate on what you owed was somewhat
lower and had the "no interest due if paid within 25 days of the
billing date" feature. But both of these were credit cards in the
meaning of the consumer protection laws.
The bank with my checking account gave me a debit card. It can be
rung up as a credit card instead, which saves me a small fee, but
either way the money comes right out of my account (well, usually a
day or two later) and is /not/ protected by the laws applying to
credit cards.
That's the real difference. Debit cards lack a lot of the legal
protections, which is why I dislike them. There may also be a
difference in the fees (above the actual cost of the purchase) and
who pays them. My understanding is that the retailer pays the fees
on credit card transactions, while the card holder pays on debit card
transactions (the card company makes money one way or the other - they
are not in the business for the heck of it). Cash out or cash back
transaction fees are paid by the card holder on either type of card.
My "secured" credit card, through another institution, /is/ credit
(as I understand it).
and from your description, it is so.

Well, you live in a larger city. Here their big sale of used stuff is
now in June, and in November they have a much smaller one of "gift
items," things in nice enough shape to be given as gifts, at higher
prices of course. Both are free to anyone, but for the bigger sale,
book dealers (or anyone who wants to pay $10) and "Friends of the
Library" (free) can get in two hours earlier the first day. There are a
surprising number of book dealers who do this... they're the ones buying
shopping carts full of books. Oh, and the prices go down as the sale
goes on. "Regular price" (e.g. $2/hardcover) Friday and Saturday, half

Yesterday (Saturday) I took one of those adult-ed (or as they call it

called "Getting Published." There were some useful things I picked up

copyright) were flat-out incorrect. OTOH I did get SOMEthing out of it.

If you're that interested, maybe it's worth taking some of those
prereqs, or learning it on your own. When I was in high school I
discovered a little-known rule that if you could pass a NYS Regents Exam
you got credit for the course, even if you never took the course.
(Except for sciences, which required at least 30 hours of lab work.)
Honors Math 9 (9th grade which was algebra) covered a lot of material in
regular Math 11 (trig), so I put in a little extra effort and took the
Regents' exam in both. I passed the Math 11 Regents, and therefore got
high school credit for the course, with my Regents Exam grade becoming
my final grade for the course. Then I spent July and August cramming
geometry (Math 10), took the Regents in August along with the summer
school students, and passed that too. I ended up as the school's first
sophomore in AP Calc BC (essentially college Calc I and II), but I
forgot the geometry at about the same rate I'd learned it, and I'm still
weak on trig. Still, it was better than spending an entire year on
geometry and another year on trig. I suppose there's a point in there
somewhere.

The IRS says using your car to get medical care is 24 cents/mile.
Of course you only get that if you itemize, which is a whole 'nother
problem entirely. (Oh, joy - tax season approaches yet again.) The
business rate is (by comparison) 55 cents/mile, but I haven't seen
anyone offering to pay that yet. It says here you can file and

to $1) and a dollar for paperback (to 0.50). The super specials are
BOGOs (By One, Get One - lots of fine print), but I think that's more
a way to move the stuff that no one would buy even at the cheap
prices. I've picked up some '50s era college text books which can be
interesting but are rarely worth paying real coins for.

Four-five years ago, one of the community colleges offered a class
of finding resources on the Internet.
What were you hoping it would cover that you didn't already know?
More of the specialized sites - shopping, reference libraries and
general stuff of local interest. For a while, there used to be a
site relating to gas prices, and it was updated roughly hourly.
There are also some local consumer based shopping comparisons sites
that don't seem to make it to national search engines.

The description sounded vaguely interesting with minimal pre-reqs
"Minimal (or no) prereqs" means a pretty basic course in any field.
Agreed, but they often turn up nuggets that you would not have found
otherwise. Had one class on Problem Solving Techniques that was more
aimed at solving puzzles than anything else, but the instructor spent
more time teaching organizing information - which in turn made the
puzzle solving easier but could equally fit into a business major
course on program management.

Sorry, I know more about that than the instructor, and even knew
what (and used) Archie, Gopher and WAIS were (she had never heard
of them). She'd also never heard of regular expressions. I went
away wondering how she had managed so sell the course to the
school administration.
Well, probably she was teaching what most people in the class wanted
to know.
That's basically true, but not being _aware_ of regex when you are

Yesterday (Saturday) I took one of those adult-ed (or as they call it
"non-credit") courses at the community college, a one-day (9 AM to 4
PM) called "Getting Published." There were some useful things I
picked up from it, but some of what the instructor suggested was
contrary to what every book I've read recommended, and at least a few
things (e.g. copyright) were flat-out incorrect.
I've encountered that far more often than I'd like. Problem one is
that nearly all of the students _don't_ know the information is wrong
and it's usually difficult (or impossible) to correct this. And of
course, if there is a test, the correct answer is what has been
taught, not what is actual fact. A couple of times, I've been able
to provide corrections the text-book author/editor, and sometimes
even get positive results. Most of the rest of the time it's a
boiler-plate response from an ignore-bot.

OTOH I did get SOMEthing out of it.
I usually do too, but it's often not to the level that I had hoped
for, or maybe even what I expected.

If you're that interested, maybe it's worth taking some of those
prereqs, or learning it on your own.
The Martian exploration stuff is very interesting, but I'm not sure

Mid-70s, I got involved in a project that not only involved a lot of

then, this is now, and I'd bet I've forgotten a large amount of what
I had struggled to learn.
Post by Adam
Still, it was better than spending an entire year on geometry and
another year on trig. I suppose there's a point in there somewhere.
It's not as if I'm using that knowledge any more, and I've got a hazy
enough memory of what things are supposed to look like that I can
find the stuff I need in the books I have.

Speaking of fuel prices, I'm annoyed that my transportation
reimbursement when I drive to medical appointments has gone /down/
from $0.28/mile to $0.165/mile. That barely covers gasoline alone.
The IRS says using your car to get medical care is 24 cents/mile.
Of course you only get that if you itemize, which is a whole 'nother
problem entirely. (Oh, joy - tax season approaches yet again.)
In my tax bracket, there's no point in claiming any deductions. The
last time I filed a long form (some years ago), I was proud of being
able to deduct a gain as a capital loss. I'd bought some stock through
the employee purchase plan (for every dollar I put in, the company put
in fifty cents), and sold it for less than the price it was bought at,
but more than my share of the purchase price. Anyway I started the
microeconomics course at the community college yesterday so in a few
months I should know somewhat more about things like that. The course
looks challenging, as I've never studied that subject, or even cared
much about it before. It's also expensive. In addition to the textbook
($100-160), we also have to subscribe to an online service (Aplia) for
some of the assignments, which will be at least another $80.

And tomorrow (1/21) is another get-up-at-4:30 AM-and-drive-to-Albany

I know what you are saying. It's getting closer each year to the point
where it's not worth it for us either. We've had to for several items
in the past - mainly capital gains/losses, and of course as a home
owner paying off a mortgage, there's that to deduct along with taxes.
When we bought our first house, our real estate agent was pounding on
us every day about saving/documenting receipts, and insisting that we
have our taxes done professionally. I was a little unhappy with the
idea that this was going to cost ~$500, but the tax guy found tons of
deductions that reduced the taxes paid enough to pay his fee ten times
over. Recent years, we've had some medical expenses (our co-pay on
big-time stuff is 15%), that even with a defined benefits program for
medical expenses (tax free use-it-or-loose-it) we've still marginally
exceeded the minimum on Schedule A. Don't know about this year yet.

Are you sure? The company chunk should have been reported somewhere
along the line as income. Both wife and I are doing stock purchase
plans and 401Ks (retirement plan?? Wazzat?), and we're intentionally
avoiding transactions on those (other than transfers among the various
allowed investments) because of tax consequences. I'm NOT looking
forward to when we start cashing out of those positions, as the tax
man (fed and state) will be giddy with pleasure.

Taxes are such a broad subject, I'd normally expect it to be covered
in several separate classes. Company income tax laws are quite
different from personal income, and then you get into sales/use and
property tax. Naturally each state is different, and different from
the feds. Local entities tend to piggyback on the state laws.

Yabbut the textbooks are _always_ expensive. In the past twenty
years, I don't think I've ever had a textbook under $35, and most
of them have been in the $80+ range. Many textbooks don't fit into
the style of books that "normal" people would be buying, and only
sell two/four times a year at the start of class. It helps if you
can shop around. I took several networking classes as a CC that were
using the W. Richard Stevens books. Their bookstore had Volume 1 for
$65 and only five miles away at Stanford, it was still $54. And with
the next class that used Volume 2, the prices were reversed. (With a
decent instructor, classes using Stevens books are worth every
penny. Stevens was a _good_ writer.) Depending on the class and
school, there may be used versions of the textbooks available.

We still have several projects running under SCCS, but most of the

In this particular project (gphoto2, of course drawing heavily on

up on SVN. Basically I'm trying to assist one of the developers on one
narrow area. I set up a VM just for this project, so I can mess up
without risking my "production" system. I chose Xubuntu for that
project, because it's popular, it seems to be considered the most
"dumbed down" or "Windowized" of the current distribution (Google
"Ubuntard"), and it's about as different from that developer's Slackware
as one can get, I think. And Xubuntu because it's lighter than Ubuntu.

And it gets tricky, because I have to keep several versions. My
"production" system has the latest official release, and my development
system (the VM) has the latest SVN tree, plus experimental bits emailed
to me by the developer, plus another copy with whatever my current
changes are. But still it's neat to know I'm on the leading edge of
SOMEthing. BTW, would you happen to know where I can find the commands
for the JL2005A toy digital camera chip? The spec sheet just gives
pinouts, so what little we know was reverse engineered... and all my web
searches lead back to the guy I'm already dealing with. I learned not
to try random commands, ever since I had a modem card and must have hit
upon the intentionally undocumented AT command meaning "reflash ROM."

Anybody's comments on doing software development as part of a team, or
being at the bottom of the hierarchy, or keeping all the versions
straight, or anything else helpful, would be appreciated!

unintended consequences. We've mentioned the concept of shopping

for researchers at other institutions and have the details? The
department web sites, possibly on another system, probably not under
www.asu.edu on the main university web site.
The NASA or JPL sites usually have a lot more material, as do some of
the trade magazines (aviationweek.com - subscribers only) if you know
where to look. But these tend to lack the commentary or "look at this"
documentation, OR can be written in absolute techno-babble, so that
can be hit/miss - fascinating, but could be better.

Have you looked for an applications guide? I'll admit it's likely
to be in Chinese or ineptly translated ``English'', which probably

it was about $60 or $80 at the bookstore, and I got it from
Amazon.uk for about £30, including shipping.
And the currency exchange fees. I don't think I've ever had an
instructor say that publicly, but it has been mentioned often
enough by class-mates. That was a nice thing about the Bay area
as there were six major colleges in a 20 mile radius in addition to
at least that many CCs.
Nowadays, Amazon.com et al. are competition for the campus bookstore
wherever you are. For this semester, I ordered it online from one of
those used book sites linked through Amazon.com. I ordered it Thursday
evening (before a holiday weekend), paid the extra $3 for expedited
shipping, and the book arrived Tuesday.

The worst textbook I was ever forced to use looked like the "author"
(Ivy League professor) had his grad students put it together without
proofreading.
Yeah - I've seen some like that - had one instructor who decided to
use his own textbook (published by Kinkos), and we students were
the effective proof-readers. I complained bitterly about that.
No, the one I mentioned was published by a major textbook publisher.

I had another course (it may have even been the same semester) where the
textbook was written by the professor and photocopied (then of course
sold at the campus bookstore), but he'd been using it and revising it
for semesters so it wasn't that bad. In the back, there was a
collection of problems, which is where our homework came out of. Each
problem had a difficulty rating from 1 (easiest) to 10 (hardest). Our
homework was in the 1-5 range. He said that anybody who solved any of
the problems rated 10 would get an A in the course. It wasn't until
later I realized that the problems rated 10 were still considered
unsolved in the literature.

And I have the last official release on my "production" system. I think
the tricky part to set up will be needing three versions on the VM --
the latest SVN tree, the latest SVN tree plus the developer's latest
improvements (as I think I'm the only other person working on this, he
just emails them to me rather than going through the "svn commit"
process for each little change), and then the latest SVN tree plus the
developer's latest changes plus whatever changes I'm trying out. I
think that deserves a thread of its own, possibly elsewhere because that
VM is /not/ Mandriva.

I haven't heard of that, so I suppose it's not too popular. I figured
some version of Ubuntu for the development VM would be the best choice
for that purpose, because of (a) its market share (meaning its eventual
share of end-users of whatever we come up with), and (b) the challenge
of making it do anything its designers hadn't thought of.

I'm still using Mandr* for my "production" system, though. I just
migrated from 2008.1 to 2010.0, and that would have been an ideal time

Actually I'm not terribly fond of 20th-century "classical" music, except

a single composer. One student suggested Bartok but I said no to that.
We ended up suggesting Berlioz, which the professor went along with.

Simplifications are good especially in pedagogy, since it allows the
students to concentrate on just the aspect that is under study. Knowing
and listing the names, addresses, weights, contents of baggage, etc of
each passenger when what you want to do is concentrate on the effects of
"sale pricing" just distracts the attention from the crucial detail. Of
course, if the purpose of the simplification is not clear to the
student, they can then get hung up on the disparity between the
simplification and reality.

While Kinkos isn't one of the major textbook publishing companies, he
did 'publish' the thing unproofread. And I don't think he ever got it

google or spamazon search.

No, I'd very much prefer him to have proof-read the darn thing himself
(not mentioned, but it had significant errors on virtually every page)

Spelling/grammatical errors? All it proved was that he couldn't use a
word processor in 1990. There were also some technical errors, but that
was probably because of the crappy source material he was paraphrasing.
Thicknet is not RG-8/U, and most definitely not RG-6/U, any more than
thinnet being TV antenna coax specifically identified as RG-59/U. The
latter two are the wrong impedance (75 Ohm, not 50) and all three have
the wrong jacket material (which is part of the DIX spec). RG-8/U was
used for the original 3Base5 (documented by RFC0895) but not 10Base5
which is RFC0894 - it's a toxicity issue.

I could accept that if I was told this was the case and what is being

<rant> My worst educational experience was as an undergrad at the Big
Name Research University alluded to above. Most of the faculty seemed
to care mainly about their research, and some of them maybe a little bit
about graduate students. Undergraduates seemed to be tolerated as a
necessary evil, and the "privilege" of a degree from that institution
was supposed to make up for their lack of concern about undergraduates.

I agree completely (that would have been a good task to assign to one of

to the "publish or perish" policy at the author's university.

A minor problem is that Ubuntu is splintering as badly as Linux itself.
Well, this is OSS... anyone is welcome to fix it up so it'll work
under their distribution of choice.
Edubuntu, Kubuntu, Lubuntu, Mythbuntu, Ubuntu, Xubuntu - that's six
from the same house, never mind the many clones. The main difference
is the default desktop. Whoopie! And of course each has their own
following who are sure that their favorite is unique in the world and
best of breed, etc.

That doesn't surprise me. A minor problem is that not everyone is

Had to look it up (my, that's an older recording) - but the review
seems to indicate that was the worst cut on the disk.
Don't forget that in the earliest days of CDs, the emphasis was on
sound quality, not necessarily performance quality.
My recollection was they were touting the dynamic range and signal
to noise ratio over other media. The performances weren't that _bad_
so much as it wasn't the goal.

I did a quick search through my collection of scores, and couldn't find
"Fanfare for the Common Man" -- just a score and parts for "Fanfare for
the Common Cold," which I believe is not by the same composer.
No, but it's good that Aaron had a sense of humor.

Richard Rodgers was a graduate of what is now Juilliard. Apparently
he was a talented composer but an rather unpleasant person.
I hadn't heard that, but you've only got to compare Artie Shaw. He
may have started out nice in the 1920's, but by the late 1930's he
had a pretty bad personality. I'm not sure if it is 'because of' or
'why' he had as many marriages.

And I'm surprised that you can even /hear/ classical guitar music in

I don't find the car noise to be that bad, and the up-beat stuff from
the Romeros sounds great. I've even got a couple of Jose Feliciano
cuts (non-vocal) that are pretty good.

Epson and HP yes - though it doesn't hurt to verify this with a quick
search. The consumables are where they are making the money - as the
competition has beaten the hardware prices into the ground. They
_can't_ price the hardware at a point that ensures making any profit,
so it's shifted to the ink/et.al. A nephew was complaining that it
was getting close to being cheaper to toss the printer rather than
buy replacement cartridges.

Thanks, Frank. As I described elsewhere, my new inkjet printer uses the
notorious HP 21 (black) and 22 (tricolor) ink cartridges. Each has 5 ml
of ink and is claimed to be good for "up to 190 pages," at US $15 each.
I am /definitely/ going to look into cheaper alternatives! This seems
to be one of the most common topics in comp.periphs.printers.

myself. Nowadays a low cost laser printer (Brother,Samsung ,et al) is
probably most cost effective ,at least the mono-colour ones ( I know

I remember that one! That was what the company issued me at one of my
jobs in the summer of 1990 or 1991... or maybe it was a 550. I remember
going through quite a few cartridges in the two or three months I was there.

If I didn't already have an antique and slow but usable color laser
which uses very inexpensive consumables (OEM NOS through eBay), I'd do
what you're suggesting and get an inexpensive monochrome laser printer.
I'd still have the color inkjet for photos or the few things where
color matters.

And Windows doesn't have one definitive version of a C/C++ compiler

with gcc. I personally am not going to worry whether what we come up
with will work under anything besides most Linux distros, since I figure
the likelihood of it ever being used on any other platform is pretty low.

My recollection was they were touting the dynamic range and signal
to noise ratio over other media. The performances weren't that _bad_
so much as it wasn't the goal.
Around 1985, one of the other music majors asked me in all seriousness
whether it was true that a recording on CD meant a better performance.
That shows how far the hype had spread. I explained that it made no
difference. A good example I should have used would be an Enrico Caruso
acoustic 78 vs. a digital recording of me. (Nearly all musicians are
far more impressed by performance quality than by sound quality, if they
have to compromise.)

In '84-'85 when CDs first hit the mass market, I was a salesman at Radio
Shack when their first CD player came out. Basically the most effective
sales pitch for it was just to play something on it. One of the more
common questions was about the repertoire available on CD, and I had a
good answer for that one: "Just go down the mall to Record World and see
for yourself."

What made me decide to get a CD player relatively early on (mid-'85,
when Radio Shack's first model first went on sale, normally $400, sale
price $260, were two things. One was Consumer Reports' first review of
players, where first they explained the theoretical advantage of digital
sound, then said they were blown away by the actual sound from all the
players they'd tested. The second was noticing that ALL the record
labels and ALL the CD player manufacturers had agreed to the same standard.

Speaking of audio history, I was just listening to a stereo recording
made on, probably, November 18 or 25, 1956. Have you ever heard one

Well, it looked like my Canon inkjet (obviously bought before I switched
to Linux) might have died. Because of my competence with hand tools, in
less than ten minutes I'd ensured it. Obvious step was to take that
sealed HP Deskjet D1430 out of the back of the closet (freebie bundled
with this computer), and Mandriva 2010.0 automatically recognized it and
installed it. (I'm not sure whether that's a good or a bad thing.) I
saw right away what everybody meant about HP being Linux-friendly.

Of course, as just mentioned the cost of consumables for it looks like
it's going to be ridiculous. A black cartridge (5 ml of ink for about
US $15) claims "up to 190 pages." (A black cartridge for the Canon had
27 ml for a few dollars less.) Since I've recently been following
comp.periphs.printers for another reason, I've noticed the folks there
seem to be familiar with nearly every possible method of reducing ink
costs. And (fortunately in this case) HP cartridges include the
printhead, so if off-brand or misused supplies /should/ trash the
printhead, replacing it will be trivial. I suppose this also means I
could switch between a cartridge (and printhead of course) with cheap
ink and one with quality ink depending on my purpose. BTW I noticed at
Staples (office supply chain) that the HP inkjet cartridges were, I
think, the only brand in those anti-theft plastic boxes.

I also finally cleared away enough stuff to get to the HP Color LaserJet
5, and turned it on for the first time since August. It's from 1996, is
the size of a window A/C, and weighs 102 lbs. empty according to the
manual. After five months of non-use, the paper jam problem that had
started when I'd replaced the drum was gone, apparently because the
black toner stuck to the drum had solidified. About fifteen minutes
with isopropyl alcohol took care of that and it's back to working about
as well as it ever did. Yes, I know it's thoroughly obsolete, but then
the cost of consumables (even OEM NOS) for it is probably as low as any
non-impact printer is likely to get thanks to eBay. I'm curious whether
there's any other printer with lower consumables cost.

Probably, at first. Radio Shack issued a few so salespeople could
demonstrate the wonders of CD. The only pieces I specifically remember
were some movie studio's opening fanfare and "Sabre Dance". Were the
demos really much worse than the ones for quadraphonic or stereo?

Another thing I learned while working there was how to use an equalizer
to make the best system sound like a $2 radio. This actually came in
handy years later for an old record that already sounded like a cheap
radio -- I just set the EQ for the inverse of those settings. I also
figured out how to set an inline echo simulator to make tap dancers
sound like they're dancing on sheet rubber. And what happens if you
take a cheap keyboard and play one of its demo tunes with all voices set
to "dog". (Excerpts available on request.)

I also learned that for things brought in for repair, the most likely
cause was just dead batteries. Second most likely cause was not
understanding the instruction manual. Third most likely was the thing
actually needing repair.

Consumer Reports' first review of [CD] players
I had mixed opinions of CR - I felt that some of the tests they ran
were so much eye-candy. I bought some of the things they listed
highly, but weren't always satisfied.
Generally when there was a big difference in quality or price, I went
with their ratings, and was usually satisfied. What I especially liked,
since often half the models they tested were discontinued by publication
time, were their descriptions of what to look for when buying
whatever-it-was. I thought they were pretty good until they changed
their format within the past five or ten years -- now for each "test"
they no longer describe the kind of product (e.g. what HDMI is) or what
to look for or any specifics on each model they've tested. All they
give you now is about a one-page best-to-worst chart without much
explanation on how they decided that. Really downhill, and no longer
very useful. I looked at issue Volume 1, Number 1 (1936) and the format
(the useful format) was pretty much the same through the 1990s.

BTW every October they have a combination open house and annual meeting
that's open to everyone. I went around 1991, or whatever was their last
year in Mt. Vernon, NY before moving to Yonkers, and I thought it was
fascinating. I've been meaning to go again ever since. Staff in the
various departments showed how they were doing their current tests,
often requiring creative methods and sometimes requiring custom
equipment. "Mythbusters" often uses similar, although more destructive,
techniques.

I wonder how much of that was due to the Phillips patent.
Phillips is also the licensor of the common audio cassette format, and
they've been pretty insistent about all cassettes being playable on all
machines. They were even reluctant to allow Dolby C as that made tapes
practically unlistenable on cheap equipment. I do recall reading about
a few machines that had a 3.75 ips option for better sound quality and
others that used 15/16 ips or even less for "talking books" or
surveillance, but there weren't many of either AFAIK.
Post by Moe Trin
Also, what was the competition - Mag tape?
When audio CDs were introduced? LPs, of course. I don't think
prerecorded cassettes, or any form of prerecorded tape (and there have
been a lot of forms), have ever had a major share of the market. My car
is one of those transitional models with both cassette and CD, and there
are still times when cassettes are better, mainly on bumpy roads and in
cold weather when CDs are more likely to fog up and skip.

I think it was either 3 or 7 channels. Of course there was also a
conventional mono print that was used in most theaters. And I read of a
1932 Duke Ellington recording where an "alternate take" turned out to be
be the same take but from another microphone, so it was possible to
synchronize them and get true stereo.

When I was on the "Cast Album" mailing list, once there was a discussion
of when each label began recording shows in stereo. For many labels it
was a year or more before there was a mass medium for stereo recordings.
The first was Columbia, which started with the next show /after/ the
one above, in December 1956. Apparently some companies treated the
stereo as a separate recording, with separate control rooms and
engineers, and sometimes even separate takes.

For the past few years, I've had three logical printers mapped to two
physical printers, and no problem with the distro or the printers
handling that setup. "ink" is the inkjet, "color" is the laser set for
color, and "bw" is the laser set for monochrome.

HP's website had man pages for some of the HPLIP utilities, but I
couldn't seem to find the executables. Turned out they were included in
the printer installation. This inkjet is considerably down the line
from the Canon i550 inkjet it replaced, which had things like "auto
power on/off" and many other adjustable settings that the HP lacks.
I'll have to see whether it can handle the 80 lb. paper I was planning

eBay has lots of NOS consumables and replacement parts, at good prices
if you plan ahead. Recent purchases (sealed OEM) include a drum for
$50, and toner at $7 for 125 g.

According to my Kill-A-Watt, that thing uses up to 1500W when printing,
60W when powered up but not printing, 30W in "power-saver" (standby)
mode, and 1W when switched off. That cost would have to be factored in
too. Also, when it's on, and for several minutes afterward, its fan,
although a steady whir, is loud enough to get annoying. I ought to look
into some way of reducing the noise, or at least redirecting it.

That's why I specified "as low as any non-impact printer" above. Fabric
ribbons (as opposed to film ribbons) are probably less, even allowing
for the extra cost of tractor-feed paper. Even less if you can just
replace the ribbon in the same cartridge, or reink it. Of course one
problem with fabric ribbons was that the print gradually got lighter and
lighter. I have some printouts from my high school's printing terminals
that were barely legible even at the time. What we used to do was have
one ribbon cartridge for everyday use, and another one we labelled
"final drafts only," so that one stayed pretty dark. When the everyday

I think it's 'Lubuntu' that has a desktop so sparce that the thing
boots in 15 seconds.
Apparently that's Ubuntu but with LXDE instead of Gnome
Sounds right
Post by Adam
IIRC when I was checking out different desktop environments about two
months ago, LXDE was more lightweight than I wanted in terms of
features. I ended up going with XFCE and am happy with it so far.
It uses a lot fewer system resources than KDE4 without sacrificing
any features I miss, although to me it looks pretty similar to Gnome.
I'd heard about it, but never actually used it. But then, just about
anything is going to be lighter than Gnome or KDE.

Hopefully not one of the "demo" CDs that I remember. While
technically fairly good, the selections were often pieces that I
wouldn't listen to on a bet.
Probably, at first. Radio Shack issued a few so salespeople could
demonstrate the wonders of CD. The only pieces I specifically remember
were some movie studio's opening fanfare and "Sabre Dance".
Might not be to bad/painful
Post by Adam
Were the demos really much worse than the ones for quadraphonic or

Perhaps - some of the ``artists'' couldn't carry a tune in spite of
all kinds of artificial aides, and some of the ``tunes'' were lacking
in quality as well.
Post by Adam
I also learned that for things brought in for repair, the most likely
cause was just dead batteries. Second most likely cause was not
understanding the instruction manual. Third most likely was the
thing actually needing repair.
Batteries go dead??? Wow. As for not understanding the manual, that
wasn't that unusual. Most of the manuals were transitioning into the
CYA mode, interested in telling you what NOT to do rather than how to
use the product.

Post by Adam
I had mixed opinions of CR - I felt that some of the tests they ran
were so much eye-candy. I bought some of the things they listed
highly, but weren't always satisfied.
Generally when there was a big difference in quality or price, I went
with their ratings, and was usually satisfied.
I had some mixed results - and no matter what they wrote, you couldn't
always impress some people with their pre-conceived opinions. I also
remember running into some regional issues - products they evaluated
that weren't sold locally, or the "almost the same" models that the
manufacturers provided to different retailers - intentionally making
comparison shopping harder.
Post by Adam
What I especially liked, since often half the models they tested were
discontinued by publication time, were their descriptions of what to
look for when buying whatever-it-was.
I don't recall the discontinuations being quite that bad so much as
the stores claiming they didn't carry/never heard of that model, but
the descriptions and explanations were useful.
Post by Adam
All they give you now is about a one-page best-to-worst chart without

Speaking of audio history, I was just listening to a stereo recording
made on, probably, November 18 or 25, 1956. Have you ever heard one
made earlier?
Wasn't Fantasia recorded in stereo?
I think it was either 3 or 7 channels. Of course there was also a
conventional mono print that was used in most theaters.
By the time I saw it, I rather doubt that any of the special theaters
retained the sound system. And 'Cinerama' was also quite limited in
distribution (was that 'Cinerama Holiday' or 'This is Cinerama' with
the camera in the nose of a B-25 where we "flew" around Manhattan, and
over... no, under all of the bridges?), but it had 7 channel sound as
well - nominal 1953 I think.
Post by Adam
Apparently some companies treated the stereo as a separate recording,
with separate control rooms and engineers, and sometimes even
separate takes.
I can understand the separation, as a good bit of the technology
(and techniques) were so completely different from monaural. Mike
placement could be tricky. But then I recall a (home-made) recording
where the mikes were clipped to a pair of glasses (just in front of the
ears). The problem was that someone tapped the guy who was wearing the
glasses and microphones on the shoulder, and he turned to see WTF. The
change in location of the instruments was VERY disorienting.

'80s.
You would ask that - it's a print out with no credit/URL. OK, it

Had the same experience with a F4480 - virtually an automatic
install and configure, although I had some minor problems convincing
an older distribution that it should handle three different printers.
For the past few years, I've had three logical printers mapped to two
physical printers, and no problem with the distro or the printers
handling that setup.
Two of the printers are classic parallel port (HP5L and FX850), while
the DeskJet is USB. The printers are on different systems, and one
distro didn't like the spool/queue settings. The install program
managed to trash the (working) setup for the old FX850, and there was
some fun convincing the printer daemon that all was wanted.

Fabric ribbons (as opposed to film ribbons) are probably less, even
allowing for the extra cost of tractor-feed paper. Even less if you
can just replace the ribbon in the same cartridge, or reink it. Of
course one problem with fabric ribbons was that the print gradually
got lighter and lighter.
The fabric also tends to wear out - but new ribbons are so cheap, I
don't bother re-inking. I'm not even sure where the re-inking
paraphernalia is hiding. I don't think I've used it in 15 years.

Cinerama wasn't just 3D. The problem was that 'proper equipment' -
the three cameras about 45-50 degrees apart, the "wide screen" that
was really made up of hundreds of carefully adjusted narrow segments,
the camera synchronizers, multi-channel sound, and the fact that the
"proper viewing" location was comparatively limited. Still, some of
the effects were absolutely mind-numbing. Economically, it wasn't
going to be a success, and I don't know how they managed to sell the

Hot water, hot air, same difference. You're taking outside ambient
which is "cold" but the dew point is even lower, and you are warming
it up. That doesn't change the amount of moisture in the air and the
result is bone dry air. This was a benefit of having 'steam' heat,
and also why grandma used to keep a kettle boiling on the wood/coal
kitchen stove all winter long. Thinking back, the coal furnace in
the cellar used to have a water reservoir that added moisture to
the hot air chamber if you remembered to fill it.

I think my humidifiers (meant for small rooms) use about a half
gallon a day.
Perhaps a different expected need. Recall we're in the desert, and
before air conditioners became as common, the homes were cooled by
"swamp coolers" - which is basically a fan pushing air through a very
porous fiber pad that has water dripping onto the pad (reservoir
and small pump). The water evaporates, dropping the air temperature
to something approaching the dew-point which can be 30 of 40 degrees
or more below ambient (which is why you freeze when you get out of
the swimming pool here until you towel yourself dry). Problem -
they're called swamp coolers for a reason as if you don't exchange
the air with (hot but very dry) outside air continuously, the humidity
inside goes sky high. A few of the best installations have heat
exchanges which exhaust the moist air, but use it to cool inlet air.
Most installs don't bother, and just exhaust the excess air from
inside.

Actually, before swamp coolers, the solution was to (try to) sleep
where there was a breeze but hang cotton sheets that were soaked in
water such that the breeze went through the sheets to reach you. It
works, but not for long - hanging up the laundry on the clothes line,
and it's dry in two hours max. If using "untreated" water, you also
have a mineral build-up as the water in the West is quite hard.
Post by Adam
Their use may also explain why my most recent electric bill was
considerably higher than expected.
Shouldn't be _that_ much - the gallon a day types (fan with a wick
type fiber pad) claim to be 70 VA max, and are around 40 VA actual.
The 4 gallon a day units (fan with motorized belt style pad) claim to
be 85 Watts max, and are around 70 VA actual. Power factor reduces
the metered (billed) energy use.

We run into a similar problem in summer, because the air conditioner
which is primary cooling (house built by/for the company that owned
the electric utility - no efficient swamp coolers in _their_ building
plans) has an icy cold coil that is chilling the air - and it's
_well_ below the desired dew point. The moisture condenses on the
coils, and is drained outside. Thus, I'm running the central air
conditioners (7 tons = 84KBTU/hr = 24.6 KW) _AND_ the portable room
coolers trying to keep the temperature/humidity at a reasonable level.

Other builders/developments are more likely to include swamp coolers
in the original design of the house as this concept provides most
(if not all) of the cooling needed for much of the year at a fraction
of the cost - blower motor similar size, and a small (maybe a gallon
per minute) circulating pump as opposed to the much larger compressor
motor and the fan in the compressor (separate fans in 'central' units
as opposed to window units) to get rid of the heat there. The
consumables are water, and perhaps an acidic cleaning compound used
several times a year to dissolve the mineral buildup. The fiber pads
need replacement every couple of years, but they're under $10 a set.

Some of the increase may also be due to leaving my computer on for

actively using it.

Speaking of power usage, I may have mentioned I'm part of a project on
improving images from cheapo digital cameras. My cheap one uses, I've
heard elsewhere, SDRAM, and so whenever it's not plugged in to a USB
port (or the computer is off entirely), it's always drawing power from
its batteries. I measured consumption at 0.5 mA when the camera is
switched off, and 85mA when it's switched on. Then how come I can't
count on my Duracell Coppertop AAAs (rated 1150 mAh) keeping it alive
for 1150/0.5 hours (about 90 days)?

In a way funny, because when Cinerama was unleashed on the world,
television was mainly black/white, wasn't stereo, the screens were
still a bit on the small size (I think we had a 15" set at the time
but anything over ~25 inch was a _very_ expensive projection system)
and national programming was limited (~30 hours a week on 3 networks).
Some major markets still didn't even have TV yet. You didn't have to
get dressed up - heck Swanson Foods had been selling TV dinners for
some time - but if you wanted to see "a show", the movies were still
_the_ place (yeah - could have been a drive-in).

Very much expected. I can't imagine anyone in the Northeast, or
(especially) Florida wanting one. Assume 80F air with 50% humidity
(which is dry for your part of town), the dew point is 67F, which is
hardly "cool" (the air conditioner is pumping out 50F or cooler air).
80F with 75% is even worse at 73F dew point. On the other hand, I
doubt we'd be buying many wood stoves or snow blowers out here. ;-)
Actually, I still have a working _de-humidifier_ that we bought in
some store in San Francisco, and have found it useful a (very) few
times. Many houses here have (wood burning) fireplaces although they
are rarely used. (The days when they might be useful are usually "No
Burn" days because of air quality issues. There's about a third of a
cord of firewood outside, and it's been there since we moved in 13
years ago. Hope the termites enjoy it, as there is just about zero

much of that state, but otherwise shares the Southwestern concepts.
I suppose that's also true of SoCal, which covers a heck of a lot
of variety. A lot of the houses tend to be wood frame with a stucco
exterior built on a slab (no cellar) often with a (cement) tile roof.
The lot sizes are usually fairly small (quarter acre / 10900 '^2 is
considered large), but that's fairly true throughout the West. In
California, we had ~1/8th acre (52 x 108 feet). As a general
statement, housing isn't that old. A friend who had gone to school at
ASU in the 1960s mentioned that the North end of town was about 6
miles North and beyond that was desert and ranches. Our house was
built in 1990 and is 25 miles North, but there are several stretches
closer to town that are still undeveloped desert.

Shouldn't be _that_ much - the gallon a day types (fan with a wick
type fiber pad) claim to be 70 VA max, and are around 40 VA actual.
The 4 gallon a day units (fan with motorized belt style pad) claim
to be 85 Watts max, and are around 70 VA actual.
I'll have to check power consumption with my fairly trusty Kill-A-Watt.
I don't know which style you have, but the main consumption is the
fan. The motor that runs the belt on the 4 GPH model is listed as
6 VA - basically a clock motor with a 10 rpm output. The big unit has
a pump and that lists at 35 VA (the fan lists at 95 VA and 40 Watts).
The 1 GPM model has only a fan - moisture is moved by wicking.

Some of the increase may also be due to leaving my computer on for
days at a time, although the CRT monitor was switched off when I
wasn't actively using it.
Five computers on one UPS and it's reporting 450 VA, including one
CRT monitor (60 VA on it's own). Reminds me, the state PUC granted a
rate increase/decrease/adjustment to the electrical supplier so I'm
going to have to recompute the costs estimates numbers, but as a wild
guess, that 450 VA on 24/7 would be about $16 a month here.
Post by Adam
My cheap one uses, I've heard elsewhere, SDRAM, and so whenever it's
not plugged in to a USB port (or the computer is off entirely), it's
always drawing power from its batteries. I measured consumption at
0.5 mA when the camera is switched off, and 85mA when it's switched
on.
Does the 1/2 mA include the refresh cycles? Current is going to be
higher, but for short bursts. There's probably one (or more) energy
storage caps (significant electrolytics) that should be reducing the
peak current (as well as a couple of ceramics as spike eliminators).

I like the idea of all those choices of distros and desktop
environments, even if it does seem overwhelming.
Something like the mid 1980s when the PC had so many choices of word
processor, database and spreadsheet, never mind the graphics and
games.
Although there seemed to be de facto standards IIRC, 1-2-3 for
spreadsheets, only a few WP apps (WordPerfect), only a few telecomm
apps, etc.
Post by Moe Trin
And unless the company/powers_that_be required a specific
one, every person was using something different.
When I worked at IBM in 1988, of course IBM had (official?) policies.
Everyone in my department used 1-2-3 for spreadsheets, some
long-forgotten word processor I didn't like, PROFS for email within the
company, and so on.

Even nowadays, although Linux is all about choice, there are obviously
some more common choices. From what I can tell, bash, OO.o, GIMP, and a
few others are the most popular in their categories. I just looked at
the latest weekly stats for this NG, and 90% of the posts were made with
just five newsreaders. And I'll guess that 80% of all Linux users are
using one of the top 20 most popular distros.

I can choose the one most appropriate for my background, my purposes,
and how I like to work.
The choice isn't as wide as it was, but it's certainly better than
the mono-culture alternative.
One thing I usually consider for "larger" programs IS the size of the
user community. That was certainly a consideration a few months ago
when I was looking for a "lighter" desktop environment than KDE4. There
may be one better suited to me than XFCE, but (a) I don't have the time
or patience to try out every single one of the hundreds out there, (b)
it's one of the relatively few that have active development going on,
and (c) it has enough users so that the accessories and answers I'm
looking for are probably out there somewhere. Of course, nothing says I
have to stick with it if I find another one that works better for me.
Post by Moe Trin
Post by Adam
What surprises me is how, since switching from KDE4 to XFCE, how
many KDE libraries and apps have been removed from my system.
I take that to mean you uninstalling unused stuff.
Yep. Often uninstalling some KDE-based app either requires removing
other KDE apps, or leaves some KDE libs orphaned. And I don't hesitate
to use (new command for me) "urpme --auto-orphans" because I figure I
can always get those packages again, should I need them badly enough.

What was kind of interesting when I started helping on development for
libgphoto2 was how many apps depended on it, many having nothing to do
with cameras. I was afraid to remove the repository version of
libphoto2 because of the number of programs it might break. What I
ended up doing was creating a virtual machine specifically for that
project, as a sort of "sandbox". That's worked out well, too. I can
try anything on it and not worry about trashing my "production" system,
and without having my "production" system inaccessible during it. I can
start "svn update" in the VM, and use my "production" system for some
other useful task instead of just waiting around.

I heard about a relatively recent showing of the movie "Oklahoma!"
(1955) in its original Todd-AO, and those present said it /did/ look
much better than in conventional 35mm.
The little I've heard about it, that would have to be some form of
re-master, as the color quality of the original 70 mm film has
deteriorated a lot over time.
Whatever it was, some people definitely did see it. And some must have
seen it more than once, possibly from videotapes or DVDs though. I
remember comments about line readings varying somewhat between the two,
especially Rod Steiger and Charlotte Greenwood. And at least one
person's opinion was that of the two, apart from picture and sound
quality, the Todd-AO version had a very slight edge over the
conventional one, probably because it was filmed first (in the mornings)
and line readings were just slightly fresher.
Post by Moe Trin
I believe I saw "Eighty Days" in both versions.
Do you remember much difference in the impact it made on you? I know
that was also Todd-AO and that Mike Todd himself was quite active in its
production.

There are some movies that come off much better on a big screen, and
many others that come off better simply because of the crowds there,
especially comedies. Maybe as opposed to TV, where IMHO very few shows
actually were an improvement when seen in color.

We've _tended_ towards some standardization, but I was spending some

only standard was that they were IBMs or clones. This was an
improvement, as we still had some CP/M stuff, and that was really
"anything goes". PCs were generally bought at the 'branch' level
which is about the equivalent of a department (30-300 people), and
the specs were set by whoever wrote/signed the purchase order. There
wasn't much in the way of actual standards - although it was often
suggested in feedback to buy GSA standardized stuff (which sorta meant
a volume discount on prices). Here, it's somewhat the same in
that you can buy what you want, but you'll run into support and

The major advantage of a package system. Generally speaking, our

A lot of the houses tend to be wood frame with a stucco exterior
built on a slab (no cellar) often with a (cement) tile roof.
A lot of SoCal houses have those wavy rust-colored roof tiles,
whatever they're made of, on slanted roofs.
The originals are simply baked clay. The color may be the color of
the clay itself, or rarely a glaze. The more common version is made
of concrete with a glaze on the outer surface. They're heavy, some
what fragile, and relatively cheap. A less common version is made of
a formed sheet metal that is dipped in a colored clay mixture and
baked. They're much lighter weight and cheaper, but are easily damaged.
The problem you run into is finding replacements when needed. There are
34 builders in the `development' (~1.5 square mile) I live in, and
each one chose a different color for the roof tiles. It's not as
obvious from the ground (quite obvious from the air), but it's
nearly impossible to get matching replacements, and not even easy
to find something "close enough".

I'm still surprised every time I see a flat roof, because around here

They certainly are common enough - it's just that there can be major

major storm series go through here, and several flat roof buildings
collapsed in Flagstaff under the weight of ~18 inches of wet snow.
We've also had flat roofs collapse here in Phoenix in a cloud-burst

each house looks different and the lots are about an acre.
"look different" because the builder oriented the buildings four
ways (swapping left/right and back/front) but it was all the same
floor plan? The first house we bought in California (~1000 square,
3/1 on a 52x108 lot) was built in 1951 in a 50 home development, and
the builder pulled that trick to make things look different. I haven't
seen new houses individually built outside of the VERY high price zone,
and they're all on small (1/8 to 1/6 acre) lots.

An acre (43560.0 square foot / 4048.92921 square meters) is a lot of
land, and most sales today are either small fractions noted above or
multiples of an acre (current radio ads for 20, 30, and 60 acre lots
that happen to be near a road but otherwise many miles from the
nearest town larger than 50 houses). Used to was an acre was a more

I know what you're saying - recall New York was one of the original
13 colonies, while most of the West was only marginally developed by
the Spanish at the same time (ignoring the natives in both cases).
This portion of Phoenix was ranch land (cattle grazing at most) up to
the late 1980s. That house we owned in California (about 7 miles
NW of San Jose) was cherry orchard in the 1940s, and the nearby land
was mainly salt marsh (the bay).

processor of _any_ kind - virtually everything is done in raw ASCII
using a dumb text editor (won't try to stir up an editor war by
mentioning which one).
I will just assume it's either some version of vi, or emacs, and leave
it at that. ;-) I actively use at least three, depending on the
complexity of what I'm working on -- vim for programs, kwrite/gedit for
simple documents without formatting, and OO.o for fancy things where
formatting matters.
Post by Moe Trin
That's really the bottom line - is it doing what you need/want.
And (as has happened in a few cases) /not/ doing things I don't want
done. Sometimes programs do more than I ask them to, either from
"helpfulness" or bugginess.

Often uninstalling some KDE-based app either requires removing
other KDE apps, or leaves some KDE libs orphaned. And I don't
hesitate to use (new command for me) "urpme --auto-orphans" because I
figure I can always get those packages again, should I need them
badly enough.
The major advantage of a package system. Generally speaking, our
users don't get in and mess with it, but our support people love the
the system.
I'm gradually learning what works best for me. On this, my "production"
system, I'm trying to stick with packages from the Mandriva repository
(or packages from elsewhere) when possible, even if it's not the newest
version, so I can be pretty confident the system will always be usable.
OTOH in the VM I'm using for developing that piece of gphoto2, running
the latest changes is obviously more important than stability.

But it _wasn't_ free. The Jones lived next door on both sides and

I'm trying to remember the last time I saw one - I _think_ there are

to be less common here because no one wants to sit in a parked car in
high summer, even after sunset.
But where you are, wouldn't they be viable in the winter? The one here
only gets about six or seven months of usable weather. Even the Dairy
Queen that's practically next door has a longer season. BTW I think the
drive-in near me is a point of pride for the locals. Hyde Park is very
much concerned about their image. Eventually they allowed a McDonalds,
but on the condition of no arches at all.

There are some movies that come off much better on a big screen,
and many others that come off better simply because of the crowds
there, especially comedies.
I think the big screen had the advantage when the scenes were
large
Yes, wide shots in particular looked much better. There's also an
advantage for comedies or cult films of having a decent-sized audience.
I finally got to see "A Hard Day's Night" on a -- well, a medium-sized
screen, and had hoped for much more reactions from a crowd of Beatlemaniacs.

Maybe as opposed to TV, where IMHO very few shows actually were an

I can certainly agree there.
"Laugh-In" is one of the few that IMHO comes off better in color. I was
surprised to learn that because of the difficulties in editing videotape
at that time (1967-74), it was simultaneously recorded as a 16mm b/w
kinescope, and all editing was done on the kinescope until it had been
approved by all responsible.

whimper about the increased electrical bill, but decided the tradeoff
was worth it.

I grew up in a house built in 1963, in pre-development days, where
each house looks different and the lots are about an acre.
"look different" because the builder oriented the buildings four
ways (swapping left/right and back/front) but it was all the same
floor plan?
Not that... well, except for a few raised ranches down the hill when the
builder had a grudge of some sort. All the designs are completely
different, except for the few pieces of new construction. I've never
seen a house with exactly the same floor plan as the one I grew up in.
Some ranches, some split-levels, and a weird one next door where
everything seemed to be a few steps up or down from everything else.

I know what you mean, though... there are whole developments with the
same raised ranch floor plan where you know where everything is the
moment you walk in the door. (And a few raised ranches with the front
door at the end instead of the center, just for contrast.)

Still not as bad as the first time I saw South San Francisco, with rows
and rows (side of a hill, of course) of the same thing over and over.

Plenty of spaces that I remember as
undeveloped land (which around here usually means tree-covered) are
now the sites of houses or stores.
I know what you're saying - recall New York was one of the original
13 colonies, while most of the West was only marginally developed by
the Spanish at the same time (ignoring the natives in both cases).
There are occasional houses around here that date back to the 1700s, but
they're mostly historic sites and not used as homes. My father
mentioned that when he lived in Bratislava it was in a house 400 years
old, but I suppose around there it wasn't even noteworthy.

Got a light meter handy? The CRT monitors do put out a fair amount

computer room, highlighting text in an xterm provides almost enough
light to be able to read a magazine.
So do most television programs, at least on a CRT set.

It took extra effort on the site's part, because they'd just
installed a digital phone system, but I also had a job-related need
for an analog line for the modem. (And when nobody was looking, I
also used it to check my CompuServe account.)
I was still working at NASA when they put in the NorTelCom digital
phones which made those 1200 BPS modems obsolete. Some people got
phones that had a DB-25 connector on them - a built-in (digital)
modem that I think ran at 19.2. That was heaven, even though a
number of PCs had a network (I think it was Lantastic, but it may
have been Vines). For most network users, the network was local

You're right about the WP, though. Fortunately most companies used

Most poured concrete isn't that waterproof. If your water table is
close enough to the surface, you'll get significant seepage. In about
1981, my oldest sister moved from an 1860s farm house that had an
un-finished cellar (cemented rock wall, a 1950s layer of concrete
put down for a floor, and another layer added to the wall to try to
reduce seepage) to a 1960s house on a hillside - the major difference
was that the exterior of the cellar walls was covered in an asphalt
layer about 1/2 inch thick, and that stopped the water coming in from
that direction. The water still came up from the "dry sump" meant to
drain the cellar, but the sump pump handled that.

paternal grandparents house (about 20 miles N of Philly) was built

development. Rather than two houses lacking central heat and indoor
plumbing (they finally installed an electric well pump in ~1950
which served the only room in the house with water - the kitchen)
and no insulation, though with a 3 acre lawn - the builder plowed
everything flat and threw up 50 ``modern'' houses, each on a ``huge''

I don't think it's that -- there used to be an unobtrusive Burger King

still open when in season. Wal-Mart was refused, though. I think they
want a "small town" atmosphere by emphasizing local businesses, and
unobtrusive ones at that. There aren't many of the major chains around
here. When a space in a mall (originally an A&P, I think) was taken by
a /local/ hardware chain (although somehow affiliated with Ace
Hardware), the town issued a statement about how pleased they were that
it was a local business.

I can see their point about wanting to keep the "small town" atmosphere
with local businesses, or at least unobtrusive ones. Otherwise US 9
would look the way it does about ten miles south, with blazing signs,
and malls separated only by car dealers. I'm sure you (and almost

I believe that's what it was. The book "Inside Laugh-In" isn't as
technical, but mentions that if a splice isn't exactly right, every
single TV set will have the picture roll over at that point. Editing a
16mm b/w kinescope was of course much much easier.

It just occurred to me that they might have been able to sneak something
(but only once!) by "network standards and practices" a/k/a censors by
having a message on a background that registered as the same grey, but
then most of their viewers had b/w sets and wouldn't catch it either.
"Car 54" (filmed b/w) took advantage of something similar. At that
time, NYC police cars were green on white. The one they used for
location shooting was red on white, so nobody would mistake it for a
real police car, but it intentionally registered as the same shade of
grey as a real one. It seemed a bit odd in a b/w series to have a
character mention having a color TV set, though.

Most poured concrete isn't that waterproof. If your water table is

I'm not exactly sure where the water table is there, but their well was
about 350 feet down. I believe the high water table is why it's illegal
to bury household pets on your own property in Long Island, although
that's not where my parents (and their deceased pets' graves) are.
Even into the 1970s, you would find floor plans in the Sunday news
paper, where you could send in for a copy of the drawings
I'd forgotten about those. Each also had a blurb making each house
sound absolutely delightful. I think nowadays one of those would be
considered "custom construction" and cost a heck of a lot more to build
than the average new house.
In the complex I'm in, the houses share no more than 4 floor plans,
but they look _externally_ different because of changes in the roof
line, trim, and shape of the windows.
Which probably impresses visitors until they visit several of the houses
there.

Bleah! Some of the houses around here, mainly the frame ones toward
downtown (1920s and earlier) have "non-traditional" color schemes. For
example, one is grey with magenta window frames IIRC.

I read recently somewhere that requiring all roofs to be white (i.e.
heat reflective) would save a certain amount in home heating costs and
associated pollution problems.

over.
That was what the market would accept - they were put up during the
post-war housing shortage. At least they allowed more colors for the
exterior paint.
The song "Little Boxes" was actually inspired by a city a little farther
south in the Bay area, but now it always makes me think of SSF.
the builder plowed
everything flat and threw up 50 ``modern'' houses, each on a ``huge''
1/4 acre (100 x 110 foot) lot. Such an improvement!
Usually these days modern construction is uglier than what it replaced
-- or if not uglier, at least totally unoriginal.

A vaporizer? I remember those when I was a kid, but I don't think
those had any motors at all, just a heater to produce hot steam.
Depends - the one I remember had a two spike electrodes and a tuning
fork type of mechanism to keep the liquid agitated.
I remember the two electrodes, and how they used to build up scale and
had to be cleaned by soaking in vinegar. Definitely hot humidity coming
out of that one.
No, this product is
labeled as a "CoolMist Humidifier" on sale for $20. It claims 1.2
gallon capacity, lasting up to 28 hours.
That sounds like my previous humidifier, which basically just pulled air
through a water-soaked filter so there was no heating at all. I never
mentioned power consumption on that, though. What I have now is, I
think, similar -- just a fan, no heater. Even if it does raise the
electric bill a few dollars a month, the occasional cleaning and lack of
cracking skin and frequent nosebleeds is worth it.

I think I've still got [ProComm] 2.4.2 on a floppy somewhere.
But do you still have a system that can read floppies? ;-)
Sure - two systems with 5.25/1.2s and 3.5/1.44s, and two more with
just 1.44s. I even have a spare of each (and an 8 inch 800k Shugart
but no controller).
Post by Adam
The bigger problem, of course, is that nowadays there are very few
dialup BBSs left to use it with.
No, the bigger problem is what can I run it on. I don't have any
systems with DOS although I do have the floppies for PC-DOS 3.3
(I think). I'm not sure any of the modems, other than the 2400 BPS
Rockwell... wonder if _that_ still works - are usable. I suppose I
could use it in IBM PC mode (everything from floppy).

Might have been Crosstalk XVI.
No, that one doesn't ring a bell (no pun intended).

Mentioned - we were more likely to be passing paper around than files.
Even more recently, like last year, I'd get things in .doc format,
and somehow my copy when printed out with OO.o often came out a page
longer than everybody else's.
If I don't get stuff as .pdf or mime-encoded HTML, the only thing
that's acceptable is raw text. Someone sent me mail in RTF some time
ago - I ran it through 'sed' to clean it up and make it readable.

[bash and other shells]
Post by Adam
That's more links than files there.
Yup. Almost as bad here.
Post by Adam
The Mandriva repository also has eash, fish, ksh, oksh, osh, pdksh,
sash, tclsh, tcsh, wish, and zsh, and maybe even others. At least I
think those are all shells.
No 'rsh'? There are two apps by that name - the 'remote shell' which
is a network function (one of the Berkeley 'r' commands), and the
original Sendmail rsh (now renamed smrsh).
Post by Adam
Nah, I had black (WECO) phones until at least 1983.
My parents were using a black dial Model 500 desk set from 1963 until
last year, and it was still working when it was "removed from service,"
mainly because so many places use keypad menus nowadays.
Were they still _renting_ that phone? In the 1980s, there was a
device you could buy that replaced the microphone retaining "nut"
(best thing I can call it) on 500 series that had a ten buttons
around the circumference, some electronics, a hearing aid battery
and a tiny speaker aimed at the microphone. Pressing the buttons
generated an audio tone appropriately. One of the guys I worked
with in Philadelphia had one. Main problem was that you were likely
to bump the buttons with your chin while chatting on the phone,
which caused it to emit DTMF tones into the conversation.
Post by Adam
I'm not sure how much it is the community rather than other
merchants disapproving of the typical fast food joint.
I don't think it's that -- there used to be an unobtrusive Burger
King around here too, next to the Dairy Queen which is also fast
food and is still open when in season.
We've got something like that in the towns of Cave Creek and
Carefree (on the North side of Phoenix and Scottsdale). The
objections are stated to be more about local color.
Post by Adam
Wal-Mart was refused, though.
Both of the towns objected to a planned Home Despot. So the store
was built a mile West in an area that is part of Phoenix along with
a major chain grocery and a dozen small/local retailers. Next,
Lowes decided it wanted to locate in the area. Cave Creek still
objected, but Carefree agreed. Now, Wal-Mart is getting ready to
build - the voters and town council in Cave Creek still objected,
but Carefree wants the sales tax revenue.
Post by Adam
I think they want a "small town" atmosphere by emphasizing local
businesses, and unobtrusive ones at that. There aren't many of the
major chains around here. When a space in a mall (originally an A&P,
I think) was taken by a /local/ hardware chain (although somehow
affiliated with Ace Hardware), the town issued a statement about how
pleased they were that it was a local business.
Ace is a franchise - the stores are locally owned, and they sell Ace
branded stuff. At higher prices than HD or Lowes, but they often
have items not carried by the other two.
Post by Adam
I can see their point about wanting to keep the "small town"
atmosphere with local businesses, or at least unobtrusive ones.
Otherwise US 9 would look the way it does about ten miles south, with
blazing signs, and malls separated only by car dealers.
Our car dealers tend to be clumped together in "auto mile" (really
"miles" long) setups on the major drags - but I know what you mean.
Post by Adam
I'm sure you (and almost everyone reading this, at least in the USA)
has seen a highway like that.
Yup - depending on the size of the town, those streets/highways can
be an important part of the tax base. The local so-called newspaper
(free to mail customers within a five mile radius) initially was very
down on the Wal-Mart application 'till someone pointed out that the
sales tax revenue would amount to about a sixth of the towns budget
and more than half of the sales would be to out-of-towners. Maybe we
can tolerate that...
Post by Adam
My uncle had color TVs in the early 1950s, but that was because he
was chief engineer at a CBS TV station - I didn't get one until...
1972 (but some of that delay was me working overseas).
I didn't have one at home until the mid-80s. Part of that was that
color wasn't really much of an improvement on most shows.
I bought a cheap 15 inch portable because of all of the hype about
the planned color coverage of the Munich Olympics. I don't know how
much I used it afterwards. I think I loaned the set to my mother
when I returned to overseas work shortly there-after.
Post by Adam
I remember standing in Montgomery Ward watching one of the Apollo
moon walks (14 or 15 IIRC) in color on their sets, as that was one of
the few things that /was/ more impressive in color. And fairly good
color and picture quality compared to what I'd expected, too.
I don't think I'll _EVER_ forget the 10-15 minute show from Apollo 8.
I also imagine a lot of people still have copies of the ``Earth-rise''
photo - I sure do. I was working in S.E. Asia during Apollo 11-16,
and the television coverage was delayed, but absolutely incredible.

[editing old video tape]
Post by Adam
You had to cut an exact integer number of frames (tolerance of a
few percent max) because of the characteristics of the phase-lock-
loop that maintained picture and color synchronization.
I believe that's what it was. The book "Inside Laugh-In" isn't as
technical, but mentions that if a splice isn't exactly right, every
single TV set will have the picture roll over at that point.
Yup! Splices were also notable for momentary diagonal shearing of the
picture in addition to a momentary weirdness in the colors, but this
was less objectionable than the vertical roll. You have to remember
that to get the frequency response for video, the tape was moving at
15 ips, and the perpendicularly spinning heads (14400 rpm) resulted
in a _relative_ tape/head velocity of ~1560 ips... and there are no
physical marks on the tape for reference.
Post by Adam
Editing a 16mm b/w kinescope was of course much much easier.
Piece of cake - first, you could _see_ what you were doing, and you
had to use a fixture/jig to keep the sprocket holes exactly aligned.
Post by Adam
It just occurred to me that they might have been able to sneak
something (but only once!) by "network standards and practices" a/k/a
censors by having a message on a background that registered as the
same grey, but then most of their viewers had b/w sets and wouldn't
catch it either.
The sponsor's sharks would see it - and the sponsor would not likely
try to pull something on their own either.

[room coolers]
Post by Adam
Fans were good enough - even when we were living in Florida.
That makes the 1920s Florida land boom a lot more understandable to me now.
Air conditioning was unknown at that time - as well as dehumidifiers.
People were not aware that things could be a lot better. And you may
recall the afternoon showers/thunderstorm seemed to cool things down
(for a short while). "Enjoy it Myrtle - there's (almost) no snow."
Post by Adam
I know one of them [ACs] is around 15k BTU/hr and you darn near
need a crane and three guys to move it around, never mind getting
it in/out of the window.
My parents just had new windows installed, which required removing
the 30 y/o AC that size out of its window. Not a one-man job. Some
of the newer smaller ones are surprisingly light, though.
The 30 year old unit should have been replaced 10+ years ago for
efficiency reasons. Replacing our 1990 models (SEER 10.0) with
"state-of-the-art" models (SEER > 14.1) would make something like that
ratio improvement in electrical use. The other problem is that the
older units used real Freon® which is getting to be very pricey.

If your water table is close enough to the surface, you'll get
significant seepage.
I'm not exactly sure where the water table is there, but their well
was about 350 feet down.
Wonder if that's going for 'better' (more reliable) water rather
than just taking the surface (less than 30 feet) water. The wells at
both of my sisters' places were/are shallow - which also means they
tend to run short late summer to fall (still usable, but needing 10
minutes to recover from doing a load of wash/taking a shower). One
of the nephews living nearby put in second well to avoid the problem
(going down ~110 feet compared to 16 feet on the original well).
Post by Adam
Even into the 1970s, you would find floor plans in the Sunday news
paper, where you could send in for a copy of the drawings
I'd forgotten about those. Each also had a blurb making each house
sound absolutely delightful.
I seem to remember they were syndicated (like the comics), and I
suspect there was conflict of interest going on. Still, I remember
people studying the plans carefully - trying to get ideas for their
own "dream" home which they never built.
Post by Adam
I think nowadays one of those would be considered "custom construction"
and cost a heck of a lot more to build than the average new house.
Of course - even though a lot of the new construction is based on
outside designs. The main difference is the number of identical (or
near identical) houses the builder is going to put up.
Post by Adam
In the complex I'm in, the houses share no more than 4 floor plans,
but they look _externally_ different because of changes in the roof
line, trim, and shape of the windows.
Which probably impresses visitors until they visit several of the
houses there.
The houses showed nicely when we were buying. After two or three
years, we probably knew better, but it was to late by then.
Post by Adam
rules limit us to four shades of the same earth colored paints.
Bleah!
They claimed the reason was to reduce the visual impact on the desert
scenery, but the houses stick up 20-ish feet, in an area where trees
rarely grow over ten feet, and those tile roofs...
Post by Adam
I read recently somewhere that requiring all roofs to be white (i.e.
heat reflective) would save a certain amount in home heating costs
and associated pollution problems.
That has it's good points - but it also depends on how the house is
insulated. Here, the attic is usually unusable except over the
garage, because they put R-30 (a foot of fiberglass) or more on the
floor of the attic over the living spaces. A few builders are now
adding a layer of aluminum covered bubble wrap just inside the roof
to increase the reflection and add minor additional R-factor. Makes
the roof cover a lot hotter, but does reduce the heat in the attic.

I remember the two electrodes, and how they used to build up scale
and had to be cleaned by soaking in vinegar. Definitely hot humidity

Even the cold units run into the same mineral buildup problem. I'm
using ``softened'' water, but still have to demineralize things about
twice a month.

At first (1963), of course. There was no other legitimate way of having

I read they swapped Apollo 8 and Apollo 9 around, partly because the LEM

it. This had the side effect of switching the backup crews when they
became the prime crews for Apollos 11 and 12, otherwise the first man on
the moon would have been Pete Conrad. What I thought was interesting
was that among the astronauts, Apollo 9 (as it became) was considered a
/much/ more desirable assignment, even though it generated much less
publicity. Reason being, Apollo 9 was the first manned test of the LEM
(in earth orbit), while Apollo 8 was just the same equipment as previous
missions... and practically all the astronauts had been test pilots.

as I'm now assisting the guy who writes the Linux drivers for them
(that's libgphoto2). [There's some Linux content for you!]

And years ago, I read of a neat destatic-izer, to take the shock out of

bulb, one end to touch your hand, the other to touch the switch or whatever.

Not exactly. You execute in the shell defined for your account in the

[compton ~]$ whatis rsh rshd rlogin rlogind
rsh (1) - remote shell
rshd (8) - remote shell server

rsh really just executes "a" command on the remote. If you wanted an
interactive shell, you used 'rlogin'. The modern versions are usually
set up with Kerboros authentication, but the old style was effectively
un-authenticated (client port >1024, hostname resolves both ways, and
the user/host combo listed in /etc/hosts.equiv or ~/.rhosts) which is
why it's a major no-no today.

That certainly fits the Ace business model. If I'm looking for
something weird, I'll try both ``nearby'' Ace stores, because being
an independent, they each stock different exotic stuff.

or in an active scene. The shearing/color thing usually lasted about
half a vertical scan (call it 1/30th sec.), so it wasn't as noticable.

Also, since the master tape had so many splices, it wasn't reusable

I can't say for "Laugh-In", but the tapes were considered expendables

Helical scan - the head is moving (repeatedly) diagonal to tape (about

1 ips, the relative tape/head velocity is around 200 ips if I remember
correctly.

No, in spite of the listing realtor beating on the sellers to make it
so (we were trying to sell the place in NorCal, so we were VERY much
aware of the problem). The realtor we were using spent about 4 hours
with us at first, and maybe showed 6 homes to figure out which
ballpark we were playing in. We then made four more sessions seeing
at least 10 homes at a time before we found this one. (I was still
working in the Bay area, and these were week-end visits to Phoenix.)
There was also on-going feedback talking about what we did and didn't
like about each one she showed us. I'm guessing we looked at ~50
homes before we settled on this one. She certainly earned her fee.

where trees rarely grow over ten feet, and those tile roofs...
I once got an aerial view of Phoenix when my commercial flight was
making a stop there, and it was really obvious from there which
areas had any construction and which didn't.
If you are looking specifically at a development where there are
several sub-developments by individual builders, the boundries
between builders are quite obvious. Roof color is probably the most
striking, shape of the houses next so. Developments tend to be
grouped in sections (nominal 640 acres, divided by the main streets
a mile apart) or major fractions thereof. Land outside of developed
or developing sections is either not suitable, is still considered
farm/grazing land or is owned by the state land trust (large areas
were set aside at statehood for later sale to raise money to support
schools). Lone houses are rare, but still obvious when they exist.

Here, the attic is usually unusable except over the garage, because
they put R-30 (a foot of fiberglass) or more on the floor of the
attic over the living spaces.
But wouldn't it still be usable for storing things that could take the heat?
Sure - but the problem is where to put things. The joists are 2x6
but they're at the bottom of a foot of loose insulation (R-30 bats
are 10" thick, and 4 foot long - R-30 rolls don't exist, requiring
two layers to meet that R factor). At best, the builder/home-owner
may install plank walk-ways to reach spots that need to be reached.
You don't want to lay stuff on top of loose insulation, because 1)
you don't want to compress the stuff as that lowers the effective R
factor, and 2) Murphy says you won't have it setting on the joists
and it's coming through the ceiling. Instead, many people put up
steel storage shelters in the back yard. In my case, I cheated and
have the shelter insulated with 2 inch foam board (R-14) and vented
to try to keep inside temps below the melting point of lead.

My humidifier just died, and I'd had it only 3 or 4 months. (There
was that unmistakable smell of a burnt-out motor.)
Wow! I really would expect the motor to work longer than that. We
have several portable fans that run 24/7/365, and after about the
first 10K hours (14 months) I find it useful to lubricate the
bearings with a sewing-machine oil - repeating every 4-6 months
there-after. The usual failure is the bearings seizing, and the
motor windings overheating as a result.

And years ago, I read of a neat destatic-izer, to take the shock out
of touching wall switches and things like that. It was just a common
neon bulb, one end to touch your hand, the other to touch the switch
or whatever.
You don't have keys or coins in your pocket? Grasp either one firmly
and use that to touch the grounded object. Heck, even a finger ring
is usually enough. The spark is _relatively_ low energy, and the
metal object is spreading the contact area reducing current density.

It's the kind of store where if they don't

That certainly fits the Ace business model. If I'm looking for
something weird, I'll try both ``nearby'' Ace stores, because being
an independent, they each stock different exotic stuff.
A few years back when I was looking for a Kill-A-Watt (home power
meter), they didn't have it -- but every other place I looked said to
try them. They have practically everything else, though. When I wanted
to make a cheap tripod mount for a webcam, they had all the parts, and

I don't recall seeing any of those when "Laugh-In" aired... and that

They also took some care in the splicing. But I don't think they were
splicing in the obvious parts - i.e. not in the middle of some dialog
or in an active scene. The shearing/color thing usually lasted about
half a vertical scan (call it 1/30th sec.), so it wasn't as noticeable.
Sometimes they did. That book I mentioned had a specific example of
using bits of their library footage as "reaction shots" when someone

Also, since the master tape had so many splices, it wasn't reusable
and therefore wouldn't get wiped.
I can't say for "Laugh-In", but the tapes were considered expendables
even when they cost 2-3 hundred bucks for a 10 inch reel (48 minutes).
You reused them if you could, but it wasn't the end of the world.

Yeah, I've noticed. We're looking for a rainy weekend. Most of the
reservoirs to the East of Phoenix are fairly full, but like most of
the Southwest, the main supply is the Colorado River, and that system
is still well below capacity. The problem we're going to run into in
this area is a lot of grass/weeds/etc. growing like crazy which is
going to make for an interesting (and early) wild-fire season. Around
the houses, both the city Fire Department and the Home Owners
Association want the weeds/grass removed as a fire hazard, but at the
same time we have to avoid overdoing it in the "dry" creeks because
they control soil erosion. I know you're getting blasted with a
nice blizzard at the moment, while I'm spending time pulling/spraying
weeds in the "lawn" (HOA requirement - less than 10% of the property
can be grass lawn) and patio areas.

Several other manufacturers were out there as well. The 6 platter

I suspect you're referring to "trap rock" though I can't think what
rock it's made from. Blue-ish color if I remember correctly. The
rock is sold here in several sizes, from (nominal) 1/4 inch up, in a
number of colors (the HOA specifies non-painted rock, but that still
leaves a wide selection). Most home-owners have selected different
colors, so you can see which property is which by the change in rock
color. My side and back yards (other than the grass lawn, pool,
patio and gardens) is mainly 1/4 inch desert tan rock, while the
front is 1 inch tan with a hint of rose. The neighbors are similar
size rock, one is gray, the other a very faint tan.

Then there are things called "washing machines" using disk packs -
6 platters holding a total of around 2 Megs, but I didn't own one
of those.
That sounds like what I saw in college, mid-'80s, only it couldn't
have been anything that late. They were about the size of a washing
machine and had disk packs on top that sort of resembled the jug of
a water cooler.
You mentioned it was an IBM system
That was later, '89-91. When I was in college in the mid-80s, the
entire student body of about 2000 was served by IIRC a Vax 11/780 that
started thrashing at about 40 users and crashing at 50. That didn't
happen much, though, mostly when final projects (and papers) were due.
I was one of the very few people to dial up from off-campus, at 1200
bps. Most students used the VT-100s or VT-102s on campus. I wish I'd
saved my network mail routing guide from then -- it listed all the
gateways between networks. Not all schools allowed students to
send/receive network mail back then. BTW this school did /not/ want to
become effectively a subsidiary of IBM, unlike the other four-year
college in Poughkeepsie, so they deliberately chose, and still choose,
non-IBM equipment.

The SCR
touch-dimmer doesn't work well with CFLs, not even "dimmable" ones.
"touch-dimmer" as in two-three step thingy? Doesn't work how?
Instead of low-medium-high-off (as it is when put in a lamp with a 3-way
switch), it was off-medium-high-off, and in any case wasn't bright
enough even at high.

I suspect you're referring to "trap rock" though I can't think what

I've managed to avoid most of the weird ones - Pascal and Fortran are
bad enough without getting into the exotics. Manuals for languages
other than C seem to disappear after a year or so (probably to the
used book store), but even though I've virtually zero chance of using
it, I've got at least five C manuals, including the mandatory K&R.
I think I had more, but got rid of the outdated ones. Except for one C
manual in Polish (which I don't know), but it goes nicely with the
Japanese (which I don't know either) manual for CP/M. A quick look
shows Pascal, C, maybe C++, and Logitech's Modula-2, which I had to buy
for "Compiler Design." (We had to use that or Ada. Come to think of
it, I took the course twice and never did design a compiler.) Of course
right after I bought it, Logitech dropped support for everything except
mice and things like that.

I still have one group project (checkers game)
It's funny how many people learn programming by creating some form of
game.
Oh, no, that wasn't my first program by a long shot. For "Software
Design and Development," the instructor divided the class into four
groups. I was in group D, and we had to write a program to group B's
specifications. The idea of a checkers game was theirs. And we had to
write specifications for a program for group B to do. (I think it was a
database for course registration.) There were five people in our group,
and Mark did about 40% of the coding, Samantha did about 30%, I did
about 30%, and the other two guys did about 0%. As the instructor
expected, we learned a lot more from doing that than we would have from
more lectures.

My share was the routine where the computer figures out its next
move, standard recursive min-max saddle point or whatever it's
called. When it was written (on IBM PC XTs), more than about two
levels of recursion with that took forever. Now it can handle at
least four or five with no appreciable delay. Of course modern
systems are at least 200 times faster than 4.77 MHz.
It's not just the clock speed - handling 32 or 64 bits at a time
also make a tremendous speed improvement.
And faster bus speeds, and improvements in practically everything. It
just gets a bit discouraging to spend five minutes thinking about a
move, and nowadays the computer responds almost instantaneously.

I can't think of any reason either, except to get in my way. Well,

standard JPEG would have accomplished that too. Or maybe to force
people to use their decoding software. Anyone here know anything about

Well, there is a few years difference in the CPUs, never mind a whole

For some reason, reading this reminded me of a bug I found in an email
system back in the early 80s. The system was written in COBOL. There
was a call from one module to another, where two of the parameters were
in the wrong order. Once I noticed this, I dug into what effect it
would have.

The email system was developed with the idea that a secretary could
reply to an email, but, if an option was selected, could have it look
like the executive had sent the reply.

It turned out, that if the 20th character of the subject line of the
email contained a capital letter Y, that option would be forced on.
Normally it worked, and the problem could not be reproduced by the
IT staff, so it had previously been written off as user brain damage.

Once I noticed the reversal of the two items in the calling parameters,
and figured out the impact, I was able to go back to the three people
who had reported the bug, explain to them what had caused it, and
finally report it as fixed.

From my perspective, the biggest disadvantage (besides having to buy a
VT-100 emulator) was that the direct dialup number was only reliable at
300 baud; to get a fairly reliable connection at 1200 bps meant dialing
the campus switchboard and asking for a certain extension. And there
wasn't any error-checking protocol for file transfers, until I looked
through CompuServe's VAX forum and found a Fortran implementation of
Xmodem, which I was able to get working on the VAX despite no knowledge
of Fortran.

forced to use different mnemonics. I'm even used to disassemblies of

a pretty uneventful recovery, which is fine with all concerned. It's
really not that much of a concern in my daily life now, except for
having to take meds 4x/day and avoiding buffets. (No way of knowing how
long the food's been sitting out there, or the hygiene of the previous

The big problem is that the weeds grow right through it
At my parents' house, the part of the backyard that's right against
the house is all pebbles, so I know what you mean about weeds -- but
with occasional surprises, like wild onions, or the start of a fir
tree.
I've "captured" a dozen acacia tree seedlings that way. I transfer
then to pots, and grow them until they're about 6-7 feet tall (in a
15 gallon container), then transplant them were I want them. The
other unwanted item is prickly-pear cactus - I can't even give 'em away.

I created a time-waster in assembly language for an 8080 (it
blinked lights, and the player had to predict which of eight
lights would be next).
How did you get the random numbers for that?
The "previous" player input caused an interrupt that read the low
three bits of a high speed (multi-kilohertz) counter, which was
stored as the 'next' light to light. Random? Close enough.

It finally occurred to me that what the JL2005C was sending to the
PC probably wasn't a finished photo, just the raw RGB sensor data
compressed somehow.
As they are windoze based, I've got zero ideas - but perhaps it's
something like zlib.

Most of my assembler programming was for the Z80, and a little for
the 8088 (and one semester for S/360). Both the Z80 and the x86 are
based on the 8080, so at least the order is similar, even if the Z80
was forced to use different mnemonics.
I started on the 8080, and the powers that be decided that seeing as
how I could do that, I could equally pick up other processors.
Unfortunately, these weren't similar (Fairchild F8, Intersil 6100
and TI 9900 - 8, 12, and 16 bit processors respectively).

Post by Adam
In this case, though, it's a disassembly of compiled C++, so (1)
there's the slop factor, and (2) all arguments are passed on the
stack, which is confusing at first.
I have had stack passing, but all of the work I worked with was
created with an assembler - primarily because the compilers of that
time-frame weren't that great.

Not many med changes this time, but cumulatively there have been a

originally 3x/week, is now down to weekly, although it's still
fasting which I hate.
Know exactly what you mean there. Last week, I had fasting for the

was my fault, because I was dehydrated and didn't realize it. The

4x/day is an inconvenience, but it's do-able as long as it's not

Still, it was a lot faster than the alternative of (essentially)
doing things with a Friden comptometer or worse - by hand. I
remember a mid-60s project where it was _possible_ to do all the
computations by hand, but GE TymeShare was _days_ faster.
When I was in high school, we were still taught how to use log tables
and trig tables. I don't even think they print those any more. I don't
even know if they teach multiplication and long (or short) division
either. When I took B/W Photog 3 years ago, I was amazed that some
students had trouble doing basic arithmetic, e.g. if it's 9 parts water
to 1 part developer and you need 300 ml total...

When I started college around 1980, I got to see (and occasionally use)
obsolete equipment on its way to being scrapped -- mechanical desk
calculators, ASR-33 TTYs, etc.

[dimmable CFL]
Post by Moe Trin
Post by Adam
Off: bulb off, 0 W, 0 VA, PF = 1.00
Low: bulb almost full brightness, 32 W, 180 VA, PF = 0.18
Med: bulb at full brightness, 36 W, 187 VA, PF = 0.19
Hi: bulb flashes (like a strobe), 0-2 W, 12-50 VA, PF=0.03-0.09
That smells as if the touch dimmer timing is matching/cancelling
the timing of the electronic ballast in the lamp. The currents
are WAY out of expectation.
Come to think of it, 36W for "100W equiv" sounds a little high.
Post by Moe Trin
I'm a little confused as I expect the
touch dimmer to be using a "standard" (single wattage) lamp. Does it
have the needed two contacts in the base (in addition to the shell)?
To save moving things around, those measurements were made with a 3-way
CFL in a 3-way socket, but the lamp socket was switched to "high" so
both contacts should be at 100% power (of what was coming out of the SCR
dimmer at the wall outlet). Was I wrong to do it that way?
Post by Moe Trin
Post by Adam
Off: zero
Low: bulb low brightness (after ~1-2 sec. delay), 11W, 24VA, PF=0.45
Med: bulb medium brightness, 20W, 43VA, PF=0.48
Hi: bulb brightest, 31W, 60VA, PF=0.50
This I expect - except the power consumption (both VA and Watts) are
higher than I'd expect - significantly.
I dunno, I thought a "100W equiv" CFL was about 27W anyway. At least
the power factors are better here. If I still have the 50/100/150W
incandescent, maybe I should put it back in there. I see CFLs are not
the answer to everything. The one next to my bed, since I do need more
light to read than I used to, is a 150W incandescent with an SCR
touch-dimmer. I had to switch from a lamp-socket-mounted dimmer to a
wall outlet-mounted dimmer because the 150W bulb was taller than the
100W it replaced.

Around here, they'd be enough of a novelty to be wanted. Just up the

pear. I don't know how it's possible in this climate, but it works.
And in my indoor window box cactus garden (from "assorted cactus

height of the window. I guess I need to dig it out and put it in
another window, or maybe try planting it on my parents' property.

I miss the buffets, although I can manage. The LUG has a monthly lunch

front of you) and was told that's okay, because it's fresh-cooked. The
more hackerly of the LUG members go straight there anyway, then eat it
with chopsticks. I guess that's part of the hacker lifestyle.

Thanks, Chris. That's news to me. Back when I learned chess (1970s),
what's apparently called "Descriptive Notation" was used everywhere I
saw -- books, newspaper columns, TV coverage of Fischer-Spassky, etc.,
so the game you cite would have been, I think, something like:

1. P-KB4 N-KB3
2. P-QN3 P-KB3
etc.

I guess they changed it when I wasn't looking. :-) That shows you how
much I've been following chess lately. I can see where SAN would be
clearer, since each square has the same designation regardless of whose
move it is -- but still, a computer program (or a human) would have to
figure out which piece was moved to there. Thanks again for the
information!

If the box you're referring to is any sort of modern device more

than the once-revered VAX 11/780.

The 780 was usually known as a 1 MIPS machine. Each of the
processors I bought in 2003 for $150 is on the order of 1000
MIPS.

In the early 1980s, I used a VAX 11/750 that had 1/2 MB of
factory RAM and 2MB of aftermarket RAM. Let's say a
well-equipped 780 might have 10X that or 25MB. The smallest
machine I built in 2003 has 512MB of RAM.

In the era of the 11/780, a 470MB disk was considered pretty
large. Now, a 750GB disk can be had for $50-60.

By many measures, a modern cell phone, maybe even some low-end
ones, have more computational power than a 780.

Hello King Camp Gillette. I remember when we got our first color
copier back in the early 1990s for the division office. They actually
kept it locked away in it's own room because everything about it was
expensive. They also got the first color printer - a Tektronix of
some kind. The rest of us had to do with B/W lasers until ~1997. It
wasn't a big deal, as there really wasn't that much of a real need
for color.

In the late 1970s, I visited the Army's Foreign Science and
Technology Center. The commander (a Colonel) had just won
approval from the
Congress for acquisition of a Cray supercomputer. He had been
grilled
by Congress critters not only on his need for that expensive machine
but on why he had to buy a more expensive model with 64-bit word
length when 32-bit word length machines were cheaper.

My guess is that if the OS and applications were written in assembler
(macro-assembler allowed), the machine I am using would outperform
the Cray that was acquired for (I think the price tag was)
multiple-million dollars.

The machine I have today is much more fault tolerant, though.
The Crays set a check-point periodically, and whenever the machine
crashed it would be restored upon reboot to the last check-point and
carry on from there.

If the Cray was not crashing now and then, it was not being
worked hard
enough!

http://www.cpushack.net/CPU/cpu1.html

The first single chip CPU was the Intel 4004, a 4-bit processor meant
for a calculator. It processed data in 4 bits, but its instructions
were 8 bits long. Program and Data memory were separate, 1K data memory
and a 12-bit PC for 4K program memory (in the form of a 4 level stack,
used for CALL and RET instructions). There were also sixteen 4-bit (or
eight 8-bit) general purpose registers.

The 4004 had 46 instructions, using only 2,300 transistors in a 16-pin
DIP. It ran at a clock rate of 740kHz (eight clock cycles per CPU cycle
of 10.8 microseconds) - the original goal was 1MHz, to allow it to
compute BCD arithmetic as fast (per digit) as a 1960's era IBM 1620.

The 4040 (1972) was an enhanced version of the 4004, adding 14
instructions, larger (8 level) stack, 8K program space, and interrupt
abilities (including shadows of the first 8 registers). Should Pioneer
10 and Pioneer 11 ever be found by an extraterrestrial species, the
4004 will represent an example of Earth's technology.

That looks pretty close - the later 8008 would easily beat the 1620.

Even a basic scientific calculator (under $10 US) would probably
outperform an early (vacuum tube) digital computer.
Funny you should mention that - I was recently reading a book from
Scientific American where they were talking about various inventions
over the years. In discussing the computer _chip_ they made the
unreferenced statement that an Intel 4004 was the equivalent of the
1945 'ENIAC' which contained 17480 vacuum tubes and weighed 30 tons.
But have you noticed that few people complain about the slowness of
whatever's modern? 20 or maybe even 10 years from now, today's
microcomputers would probably be considered ridiculously slow and
quite limited.
Ten years is a heck of a long time in the growth of computers,
whether micros or mainframes. But when was the last time you booted
a (merely) ten year old computer? Look at the 'BogoMips' mini-howto

-rw-rw-r-- 1 gferg ldp 181512 Mar 2 2006 BogoMips

to gain some pseudo-scientific indication of how far things have come
and note that it was last revised 4 years ago. My home firewall box
is the remains of a 386SX-16 laptop of undetermined age, and glories
in doing 2.20 BogoMIPS, while this box is a dual Athlon which claims
to be 10850 BogoMIPS. "More Mistakes Per Second!!!"

In the late 1970s, I visited the Army's Foreign Science and
Technology Center. The commander (a Colonel) had just won
approval from the Congress for acquisition of a Cray supercomputer.
My guess is that if the OS and applications were written in assembler
(macro-assembler allowed), the machine I am using would outperform
the Cray that was acquired for (I think the price tag was)
multiple-million dollars.
http://www.cray.com/about_cray/history.html

The first Cray-1(TM) system was installed at Los Alamos National
Laboratory in 1976 for $8.8 million. It boasted a world-record speed
of 160 million floating-point operations per second (160 megaflops)
and an 8 megabyte (1 million word) main memory.

Comment: We don't rate our computers in MIPS (Millions of Instructions
Per Second) that often any more - FLOPS are where it's at, in large
decimal multiples thereof (giga =9, tera =12, peta =15). Intel had an
experimental chip that was doing 1 TeraFLOPS in 2007, and if you look
at the "Top 500 Supercomputers List" buried somewhere on the
http://top500.org web-site, you'll find them speaking about a number
of systems running better than a PetaFLOPS.

http://www.theregister.co.uk/2009/06/23/top_500_supers_0609/

The two machines at the top of the June 2009 ranking are exactly the
same as they were on the November 2008 list. Number one is IBM's
hybrid Opteron-Cell "Roadrunner" machine, which the U.S. Department of
Energy has installed at Los Alamos National Laboratory. The machine is
currently using dual-core 1.8 GHz Opteron chips and 3.2 GHz PowerXCell
8i co-processors, delivering 1.1 petaflops of number-crunching power
(the same performance it had last November). Roadrunner has 129,600
processor cores in total and runs at about 75.9 per cent of peak
theoretical throughput. (Moving up to faster 40 Gb/sec InfiniBand
switches would probably boost performance on Roadrunner without adding
cores to the box).

Number two on the Top 500 is the "Jaguar" Cray XT5 cluster installed
at the DOE's Oak Ridge National Laboratory, which is made from 37,538
of Advanced Micro Devices' quad-core "Shanghai" processors running at
2.3 GHz and delivering 1.06 petaflops of oomph.

Hate to see the electric bill for these things.

The VAX was an improvement - substantial - over the PDP-11, but it
was under powered compared to some mainframes.
I thought it was a minicomputer, and wasn't supposed to be a mainframe.
Well... it's amazing what people think they can get out of a computer.
Got some time to waste? This is a mini-howto:

Probably this box I'm using now is more powerful.
I see Robert Riches has replied to this. The 11/780 was the first
system that was sorta rated in MIPS - about 1.0. For perspective, if
you look at earlier (third generation) systems, the IBM System 360
wasn't even that fast until you got to the 360/75. The VAX 11/780
sorta belonged to the fourth generation, and a high horsepower example
there would be a 370/168 which was nominally about 3.5 MIPS. If you
were to try to compare to a modern x86 PC, you'd probably find a 80486
able to outperform an 11/780 or 360/75, and even the first Pentiums
would give a 370/168 a run for it's money. A SuperWhizo 64 bit CPU
(AMD or Intel) is so far ahead of a 370, it's not even worth the effort
to try to compare them.

When I was in high school, we were still taught how to use log tables

I suspect you're right - but who needs them when even a $5 calculator
can do the math for you. (I still have several copies of both tables.)
Post by Adam
I don't even know if they teach multiplication and long (or short)
division either.
Not to the extent we learned it - no. They teach the concepts, but
doing the actual calculations takes to much effort. I rather doubt
anyone is memorizing the multiplication tables either.

When I started college around 1980, I got to see (and occasionally

desk calculators, ASR-33 TTYs, etc.
Still have a typewriter? I do (Olympia portable I bought in 1965
for US$69.50 new from the Brookline [Mass] Typewriter Company - still
has the receipt taped inside the cover for US Customs - and a Pan Am
name tag showing the address I lived at back then). _Mechanical_
desk calculators are likely to be kinda rare today although an
electronic one with a built-in printer isn't unheard of. ASR-33s...
I last used a KSR-33 (TI with thermal paper printing) as late as 1993.

[dimmable CFL]

Post by Adam
Low: bulb almost full brightness, 32 W, 180 VA, PF = 0.18
Med: bulb at full brightness, 36 W, 187 VA, PF = 0.19
Come to think of it, 36W for "100W equiv" sounds a little high.
With that kind of currents - not unreasonable. What is unreasonable
is the currents to start with. WAYYYYY to high.
Post by Adam
To save moving things around, those measurements were made with a
3-way CFL in a 3-way socket, but the lamp socket was switched to
"high" so both contacts should be at 100% power (of what was coming
out of the SCR dimmer at the wall outlet). Was I wrong to do it that
way?
Without putting an O-scope on it to look at the waveforms, I don't think
so. It was just a bit confusing.

Hi: bulb brightest, 31W, 60VA, PF=0.50
This I expect - except the power consumption (both VA and Watts) are
higher than I'd expect - significantly.
I dunno, I thought a "100W equiv" CFL was about 27W anyway.
As a single rated lamp, yeah. But what you've got there is a "30" and
"70" Watt equivalent operating in parallel. You may note that the
"100" Watt equivalent should be _around_ 27 Watts and a third Amp, or
about 40 VA (PF ~.67) - that's what I meant about being higher. I'd
be looking at the propaganda on the box (which MAY also be printed on
the ceramic base of the lamp).
Post by Adam
If I still have the 50/100/150W incandescent, maybe I should put it
back in there.
Or at least look at the box to see what it claims to do.
Post by Adam
I see CFLs are not the answer to everything. The one next to my bed,
since I do need more light to read than I used to, is a 150W
incandescent with an SCR touch-dimmer. I had to switch from a
lamp-socket-mounted dimmer to a wall outlet-mounted dimmer because
the 150W bulb was taller than the 100W it replaced.
You can probably find larger harps (the metal thing that supports the
lamp shade), but yeah it's a pain. The floor lamp in the library is a
150 Watt equivalent CFL, and I had to buy harp extenders to allow the
bulb to fit. We don't do much reading in the bedroom, so the lamps
there are small (25 or 40 Watt equivalents).

Many of the lesser roads are built that way. As long as the wheel
loads are relatively low, it's fine - and cheap. The strength is
in the base, not the wearing/protective layer.
I suppose if I lived there I'd get used to them, but as a visitor I
wasn't accustomed to the slower speeds (and greater road noise) they
required.
Don't forget that a lot of the 'country roads' are little more than
paved versions of what was there when it was still a colony. It
started as a graded dirt path, and the only improvement was the
rolling the surface got from the wheels (and the filling of the
resulting ruts) before it got paved in the early half of the last
century. Were it a "modern" country road, they might start by
grading and compacting it (sheep's foot roller) before putting down
a layer of engineered fill (clay and gravel) which is then covered
with black-top. Doing much more is cost prohibitive unless the
traffic load requires it.

Around here, they'd be enough of a novelty to be wanted. Just up

prickly pear. I don't know how it's possible in this climate, but

The "Sunset Western Garden" book suggests they don't like the cold,
but they should survive a light freeze undamaged and a worse freeze
might cause the "leaves" (pads) to split.

And in my indoor window box cactus garden (from "assorted cactus

Could have been a text notation of 'from-to'. Used to be used in

Aren't chess matches still reported that way?
Can't prove it by me - the newspapers I've seen over the past few

Chris Johnson's response, but can't say I've seen that form of
reporting. I haven't played chess in maybe 40 years.

Difference is, in checkers one move can have more than just a
starting and an ending square, if there are multiple jumps.
Vaguely, I recall that it listed each of the intermediate squares
too, but it's been a LONG TIME since I've seen matches reported. A
reproduction of the WW2 Army magazine "Yank" shows them numbering
the squares (1-32), and reporting the moves in the form "4-11-22-29"
for a series of jumps from one corner to the other.

one pill each.)
Piece of cake. I've had some (mainly pain-killers) where they wanted

"Mongolian grill" there (you choose a bowlful of raw stuff, they
stir-fry it in front of you) and was told that's okay, because it's
fresh-cooked.
"Mongolian grill" vs "stir-fry"... cue the Burger-King ads about
grilled verses fried. ;-) There are several 'cook it at your
table styles" whether it be frying (anything from an electric fry
pan or wok up to you seated around a standard solid grill as at
``Benihana of Tokyo'' which actually originated in LA), or cooking on
a small grill (charcoal or gas). Some places, the cooking experience
is half of the show.

The more hackerly of the LUG members go straight there anyway, then
eat it with chopsticks. I guess that's part of the hacker lifestyle.
Eating with chopsticks in the West is more often a show-off type of
thing - I see people demonstrating their ``skill'' by using chopsticks
to pick up cashews or cocktail peanuts. If they want to really show
the skill, try breakfast - specifically {hot|pan}cakes and soft cooked
eggs (good oriental foods). The skill shows in using the chopsticks
to separate bite sized chunks of both separately.

My mistake there. What I was using wasn't a dimmable CFL, but a 3-way

Yep, got an electric typewriter as a high school graduation gift
(like most HS students at that time). It's now in my parents'
basement, next to the (still working) manual typewriter my father
used as an undergrad.
My sister has the Underwood that my father owned. I don't think
she uses it either.

Does the ribbon still have functional ink? One of the office supply

About four years ago, I spent a day cleaning and de-gunking it, and
gave it a light coating of a Teflon lubricant.

[dimmable CFL]
Post by Adam
My mistake there. What I was using wasn't a dimmable CFL, but a
3-way CFL. I could get the dimmable CFL out of the closet and repeat
these measurements if it would be worth it.
If you're interested, it might be worth it. The electronics on an
electronic version of a fluorescent is basically a pulse width
modulator - varying the width of the pulse to control the amount of
energy, compared to a classic (inductive) ballast which just limits
the current via Ohms law. The non-dimmables tend to want to have a
"fixed" energy, and a dimmer interferes with this. The dimmables
limit to a maximum (but not minimum) energy. You've still got to
supply enough energy to get the lamp started, and the arc requires
a minimum current, so the only way to dim the lamp is to reduce the
time that the arc is on - and that way leads to flickering.
Post by Adam
I bought the 3-way CFL for the LR lamp with a 3-way socket. The
dimmable CFL was meant for my nighttable with the SCR touch-dimmer,
but even its brightest wasn't bright enough for me. That's why it's
back in the closet.
I found that the common "100 Watt" CFL (1600 lumen, 23 Watts, 40 VA)
wasn't as bright as I'd like. They're OK for general lighting, but
the serious reading lamps are "150 Watt" CFLs (2600 lumen, 40 Watts,
72 VA, PF ~.56). Those aren't 1.5:1 ratios, so I'm not sure where
they come up with the idea of 150 Watt equivalence.
Post by Adam
I found the box (it's what I used to store the 50/100/150W incandes-
cent it replaced) and it says 50/100/150W equivalent, 12/23/29W.
The 12 and 23 look right - the 29 seems low. How many lumens?

Don't forget that a lot of the 'country roads' are little more than
paved versions of what was there when it was still a colony.
Ah -- but /which/ colony? ;-) The land was claimed by both New York
and New Hampshire. Now it's the separate state of Vermont, the first
one after the original 13.
Go back further - English colonies.
Post by Adam
It started as a graded dirt path, and the only improvement was the
rolling the surface got from the wheels (and the filling of the
resulting ruts) before it got paved in the early half of the last
century.
I know US 9, which is the main N-S thoroughfare through here, goes
back to pre-revolutionary days, complete with some of the original
milestones along it. I believe it was paved around 1927.
That sounds reasonable. Outside of the main cities, paved roads were
comparatively rare because they were so expensive to build. Asphalt
wasn't very common until at least the early 1890s, and building a
road out of concrete took a lot of material, especially where it might
freeze. Bricks might be OK if the drainage is good, but would also
be a problem where things may freeze. Building of stone - especially
fitted stone (as done by the Romans) is expensive and can be a
maintenance nightmare.

I added about a half-dozen features to a 9K WP program (limited to
64K including program, resident OS, and document) without taking a
single byte away from the space available for the document. That
took considerable disassembly and a knowledge of the size of each
instruction.
Ran into similar problems with the early work - I didn't have
access to an assembler, so we were forced to stay within the same
size to avoid having to recode all of the jumps.

I've always been thirstier than average. When dialysis wanted a
24-hour collection, they had to give me two 3L containers. Now,
post-tx, I'm actually encouraged to drink more fluid.
The "standard" recommendation is something like 60-100 ounces of
fluid per day, and that's quite easy in the warmer climate. The
larger sizes of soft-drinks they sell here may be as big as 96
ounces. I can go through that on the drive home in the afternoon.

There are several 'cook it at your table styles"
This isn't that fancy. It's a gas grill at the back of the
restaurant with a round flat cooking surface about 4' across, and
the chef (or cook) stirs the things with wooden sticks as he walks
around it. Definitely not fried in oil.
That's usually a steel cooking surface - and I've always seen the
foods cooked with a faint hint of fat/oil - there may be enough from
the meat itself, but for vegies, the cook may start by spreading a
small amount of some form of oil - perhaps a teaspoon or so. It's
mainly to keep the food from sticking to the cooking surface.
Post by Adam
Some places, the cooking experience is half of the show.
I finally realized that above a certain price range, restaurant food
doesn't (and can't, really) get any better. What you pay extra for
is the service and "entertainment".
That's one way of putting it. I tend to agree with this view.
Plug 'teppanyaki' into your favorite search engine.

[use of chopsticks]
Post by Adam
If they want to really show the skill, try breakfast - specifically
{hot|pan}cakes and soft cooked eggs (good oriental foods).
E.g. egg foo yung, which is sort of an omelet.
Or a baked (or steamed) fish which is served whole.
Post by Adam
The skill shows in using the chopsticks to separate bite sized
chunks of both separately.
Some of them use the chopsticks for everything except soup and dessert.
A lot is going to depend on the type of soup - those with larger
pieces of vegetables/meats, or with a long noodle would be eaten using
chopsticks and drinking the liquid part. The lighter style is normally
eaten using that ceramic spoon. For some other (large) item, you use
the chopsticks to pick it up and bring it to the mouth so you can bite
off a piece. Not all foods are pre-cut to bite sized pieces.

first generation people in the Bay area. My wife also lived in Japan
as a child, and picked up some of the food ideas as well.

As far as exotic cooking, I'll try almost anything from anywhere. If I
want to prepare it myself, I can always go to the library of the
Culinary Institute of America. Once I went there to find a Swiss
recipe, and they actually had half a shelf of books specifically on
Swiss cooking.

That reminds me of a nice documentary on one of the cable channels about
ten years ago that I fortunately taped. It was called "American Eats"
-- I think they later made a series out of it. One segment was on
Chinese food -- not as it is in China, but what we in America think of
as "Chinese food" which I learned is mostly Cantonese because that's
where most of the first Chinese cooks in this country came from.
Another segment was on the sandwich, and they said something like "If
anybody anywhere in the world comes up with some new kind of food,
somebody in America is going to try to make it into a sandwich."

Well, the color laser printer I'm now using for my everyday printing
originally sold for $7500 (later reduced to $5000). I could probably
get a better one for under $500 now... but cost of consumables would
probably bring it back to $5000 pretty quickly.
Hello King Camp Gillette. I remember when we got our first color
copier back in the early 1990s for the division office. They actually
kept it locked away in it's own room because everything about it was
expensive. They also got the first color printer - a Tektronix of
some kind. The rest of us had to do with B/W lasers until ~1997.
One reason I'm still using this thoroughly obsolete HP CLJ5 is that the
cost of consumables is only a fraction more than the cost of the paper
alone. (Not counting the cost of electricity, though. Time for the
Kill-A-Watt again, after I measure the CFLs.) Even my 2003 Canon inkjet
was made before the current business model had taken effect. My current
color inkjet is a 2007 HP, and I'm going to get back into refilling
cartridges again. (Although I'll probably still use a cartridge with
OEM ink for anything really important.)

BTW during my stay at IBM mentioned above, some of us had color
dot-matrix printers. When was the last time you saw one of those? :-)

That looks reasonable, but I'd expect the "high" wattage to be in the

Yup - mainly a result of the closed society, and the limited travel it
permitted. People from the interior - Szechuan, Hopi, and the like -
didn't travel very far. Come to think of it, up to the mid 1850s,
there were only the five "treaty ports" open - Canton, Amoy, Foochow,
Ningpo and Shanghai. Then US had trade relations with Canton as early
as 1784 though I don't think _diplomatic_ relations until ~1870.

If I am informed correctly, one of the reason the Romans built
things so sturdily is their policy that the engineer who designed
an arch was required to stand under it while the scaffolding was
removed. In an age without Finite Element Analysis, I would be
inclined to design an arch _VERY_ sturdily!

Biggest problem with ProComm and modems is that Procomm is so old
it only runs up to a _port_ speed of 19200 BPS - which puts a severe
crimp in the already limited modem speeds. Another minor problem is
that it's only aware of the classic COM ports. Thus, my PCI modems
which use completely different I/O addresses won't operate. But I
do have a 2400 and 14400 BPS ISA modem... and two boxes that still

It really can be a complex but interesting subject. There are so many

Adam Smith's The Wealth of Nations addressed _political_ economy,
and presented ideas useful at the time. U.S. economists from
Samuelson onward have attempted to remove the "political" from
the system, to make it a rational approach to production and
provision of goods and services at minimal cost. This approach
is fine for managers looking for efficiency in a closed system
(i.e. for middle management in a large corporation), but fails
miserably in any arena where competition is rampant and not
subject to constraint "to be nice."

Put differently, IIRC Clauswitz declared that war was a
continuation of diplomacy by other means. For most of the world,
it was and remains the other way around. Diplomacy is a
continuation of war by other means. And for many, at both
national and corporate entity level, economics is a continuation
of both in yet another format.

ftp://ibiblio.org/pub/linux/docs/faqs/Linux-FAQ/

at least I _think_ that's the right document:

-----
Q: What are the Minimum and Maximum Memory Requirements?

A: Linux needs at least 4MB, and then you will need to use special
installation procedures until the disk swap space is installed. Linux
will run comfortably in 4MB of RAM, although running GUI apps is
impractically slow because they need to swap out to disk.

Some applications, like StarOffice, require 32 MB of physical memory,
and compiling C++ code can easily consume over 100 MB of combined
physical and virtual memory.

There is a distribution, "Small Linux", that will run on machines with
2MB of RAM.
-----

Now that's a bit of an early question, because I specifically
remember Red Hat 3.0.3 Picasso (Spring 1996) wanting 4 Megs and
_recommending_ 8 for X and/or a power user. This was (of course) well
before KDE or GNOME, but I did run RH 2.1 and 3.0.3 on a 4 Meg box.
It wasn't great (compared to SunOS 4.1.3 on a 4/40 with 64 Megs), but
it was quite usable (and several tons cheaper).

But RAM required /is/ increasing, and many distros /are/ adding all
the eyecandy too. Last year I acquired a 486 system with 40MB RAM,
and wasn't able to get any distro to work on it. Even the "minimal"
ones wanted at least 64MB RAM.
Well, look at the size of the kernel.

[combining two replies while moving them into new thread]
Maybe "microchip" isn't the right word, but our guide referred to
them as "chips". They probably ended up as part of some IBM
mainframe.
That wasn't the only gear using chips.
True, but remember this was a tour of IBM Poughkeepsie in 1979. I don't
think IBM made chips for use anywhere other than their mainframes then.
Recall what TI invented was
creating multiple components (transistors, diodes, resistors) on a
single piece of semiconductor. The early chips were pretty simple.
But, in quantity, still cheaper than individual components at that time,
right?
Today
those same components are shrunk to fractions of a millionth of a
meter (~0.00001 inch), and there is a shed-load more of them.
And CPUs are microprogrammed, not made of separate NAND/NOR gates. I
believe the Z80 (introduced, what, mid-70s?) was one of the last CPUs
actually made from individual gates. That means that theoretically
there were equations for all of the output pins, although I'd hate to
see them.
When I bought
most of it in '83-'85, I don't think the term "entertainment center"
was in use, or at least no one would have applied it to my pile of
pieces
The term 'entertainment center' was certainly in use then - and a bit
before. It refers to the furniture that held all of the electronics
and maybe had doors (glass or "wood") that could close things off
when not in use.
True, but no one would have applied it to the components themselves
then. Back then, there were TVs and stereo systems, and not necessarily
connected or even near each other. Nowadays "entertainment center"
means a giant TV screen, Dolby 5.1 sound, and all that.
I think black for home audio came in later in the '80s.
My Fisher system is black, but I have NO idea when we bought it. I'd
be making a very wild guess to say ~1982.
I worked at Radio Shack from '83-'85, and I think black for home audio
was just coming in when I left. For cameras, I think black as an
extra-cost alternative to chrome was around since at least the '60.
Black was considered "classier" and "more professional" even though the
camera was otherwise the same. I think black/silver for computers
replaced beige around 2002-2005. (Does anyone know the official name
for the color used on IBM PCs and similar equipment?) There are color
trends in everything -- I suppose it's meant as an incentive for status
seekers. It wasn't until fairly recently that any vehicle besides a
school bus, cab or sports car was painted yellow; now it's all over the
place.

[reply to second message starts here]
I'm still proud that out of 22 rolls of Tri-X I developed for that
class, I didn't ruin or even damage any, even though I had no
darkroom experience.
I don't remember it being that difficult once you understood what was
going on. Basically, just follow the recipe and so on.
Well, the instructor had to explain, in considerable detail, what
"dilute 5:1" meant, and some students still needed a calculator.

The only time I specifically remember any film ruined in development
there was when another student didn't load it onto the reel correctly
and parts of the film were touching each other and so didn't get developed.
I thought the hardest part was getting the film onto the reel, which
had to be done in TOTAL darkness and usually took me several tries.
and you couldn't come out during and get some help - yeah, that was
fun. I think I was given practice using some developed film and going
through the exercise were you could see what was going on - then two
or three run-throughs wearing a blindfold while someone was there to
see how you screwed up before going live.
I wish we'd had more practice in class -- I'm not sure I had /any/
before developing roll #1.
Other than the Brownie, my first camera (mentioned before - an Ansco
C-3 shooting 626) had two shutter speeds and two lens openings. I can't
remember but think it probably had a focus adjustment. Hey, it worked.
My first camera was the equivalent of a Brownie, and I jumped straight
from that to an all-manual SLR. I'm not familiar with an Ansco C-3 --
by my time the company had been renamed, or maybe taken over, by GAF,
General Aniline and Film. I am familiar with the Argus C-3, a/k/a
"brick". During the class I actually shot one roll using it, which made
me understand why so many of its owners used it as a trade-in.
When I encounter an unfamiliar 45, it's often not hard to figure out
which was the A side -- it's the one they spent some time on. The B
side often sounded like it was written and recorded within 15 minutes.
And that probably been the total amount of time it was played.
"B side," like "B movie," is another one of those concepts that seems to
have fallen by the wayside.
At least three times so far, I've called or written radio stations to
ask what piece they'd played, and have always gotten answers so far.
They expect that question.
Don't they have play-lists on their web-site?
Not in the 1980s they didn't.
On the other hand, I do buy CDs (mainly re-releases) based on the
artist name alone.
Only by performer? Never by song title or composer?
I wouldn't say "never", but it's not very common. For example, I've
probably got 6 or 7 versions of Copeland's "Variations on a Shaker
Melody" / "Appalachian Spring" / nee "Simple Gifts", yet I enjoy
the rendition by Yo-Yo Ma and Alison Kraus greatly.
I think what I have the most of is "The Mikado," about a half-dozen
complete or "highlights". My current favorite is the 1926 D'Oyly Carte.
I never got into that 20th-century stuff -- I had a /terrible/ time
having to write a paper on a Bartok string quartet.
Mel Blanc's book ("That's not all, Folks") - he mentions that the
sponsors had people on set making sure you were smoking the specific
sponsors brand... on _radio_ no less.
I heard of people getting away with putting their own brand into the
sponsor's package. Might have been Oscar Levant.
(As opposed to Lincoln, where I don't think even today's doctors could
have done much for.)
Smithsonian magazine, January 2010 issue, pages 8-10. Guy by the
name of Phineas Gage.
I've heard of him. Survived, but with quite a personality change.
(the helicopters shown in M.A.S.H. really did make a difference).
The original novel, written by an M.D. who'd served in one,
Richard Hooker
Pseudonym for Richard "Horny" Hornberger, M.D., plus I believe at least
one uncredited persevering literary agent. Sidenote: the TV series says
"Developed by Larry Gelbart" but, apart from the pilot, there's no
mention of what it was developed /from/. Gelbart hadn't noticed this
until I asked him about it, and he said it must have been a
20th-Century/Fox front office decision.
goes into some detail about the medical practices used.
getting the patient quickly to the operating table with competent
doctors and all made a substantial improvement in the survival rate.
And triage -- figuring out which patients were most urgent. There's
some interesting detail on that in the novel.
Can't
tell if that was a joke or not, but they were definitely anti-smoking
at that facility (Wright-Pat).
USAF test pilot and astronaut-in-training Michael Collins said in his
autobiography that objectively (from the annual physical), quitting
smoking improved his health more than everything else (diet, exercise,
etc.) combined.

That really was not the selling point, initially. Size, weight,
and ruggedness were the qualities of concern. Quantities
produced were low, and prices high.

Think guidance system for Minuteman ICBMs.

Perhaps not for Poughkeepsie. I remember some military avionics that
I understood to be IBM, and it did have some DTL (I think) chips. But
talk about "long ago and far away"!

Cost of material - no. Cost of _installed_ material, probably. By
combining components into a pre-wired assembly, you're going to
decrease the line assembly and testing costs never mind the overhead
costs of inventory control and restocking. The other advantage was
that the components were designed to function, and lacked some of the
"wasted" real-estate and power consumption. Think how big a TO-18
transistor such as a 2N2222 is, and the fact that you'd run that at a
higher current level (maybe 30 to 50 milliwatts disapation). How
about the collector load resistor - a 1/4 Watt carbon most likely
(1/8 Watt were more expensive and more of a handling problem).

That doesn't smell right. Yes it can be done, but it takes a minimum
of two NAND gates to make a flip-flop (four if it's clocked), and
that's a lot of waste compared to three transistors, six diodes and
four resistors. Heck, quad-D latches were even common by 1972.

Wow - loading the film onto the reel isn't that intuitive. Now that

just opening the roll of film (feel for this piece of plastic,

/some/ sense out of. One unexpected problem was that a lot of his
writings had never been translated, and the instructor was the only one
who knew any French. BTW for those who do know French, some of Satie's
scores have very funny comments in them.

I don't know if your PBS radio carries "Performance Today", but one of
the weekly features is a "Piano Puzzler" - where Bruce Adolphe (some
form of current classical composer I guess) takes a piece of music
(which can be _anything_ from old classics to children's songs, show
tunes - even something by the Beatles) and plays it in the style as
if written by some other composer - think "Norwegian Wood" as if
written by Bach, or "The Great Gate of Kiev" in the style of Grieg -
and a listener is invited to identify the music and the composer being
imitated. I usually get over three quarters of the music, but have a
horrible success rate identifying the composer.

Not intentionally - but some of the missions wound up lasting far
longer, and the Hanoi Hilton didn't seem to have cigars on the room

Even when extended hospitality was not included in the package,
duration of the trip could stretch.

One guy was taken by helicopter to a remote mountain, where he
rappeled down, verified tail number and aircraft and engine
serial numbers, counted the bodies (verifying they were
unmistakably dead), and reported his findings to the helicopter
loitering in the area.

He was told, Great job! We owe you a drink when you get back.
And the helicopter departed.

Just part of the job.
