"Pipe" is described by it's nominal diameter and strength ("schedule"). Nominal diameter is neither internal nor external. ex: 4" schedule 40
"Tube" is defined by the external dimension (not necessarily diameter) and wall thinkness. ex: 4x4x1/4 (a square tube, 4" on a side, with a 1/4" thickness.)
I store all of mine in a single CaseLogic binder. The covers go in behind the discs in each slot. When it gets full, I just go through an throw out about 10% to make a little more room. Voila! I do try to comsolidate data before I throw the extras out. Of course, I can fit everything on less than 100 CDs at this point, since I don't keep old software versions.
Interesting. We had the same problem with CDs back in the mid90s at NASA's Goddard SFC. Little tiny dots on the backs of discs..like dye was "leaking" out of some of the burned ares. That's not what was happening, but that's what it looked like. It make the discs mostly unreadable. These were '95 era gold discs. I have never seen the problem since. *shrug* I left in '97 so I don't know what was done to mitigate the problem.
FWIW, I don't think we stored them in paper - they were kept in the original jewel boxes or *gasp* cartridges.
At first, It thought you said Economics. Reminded me of my Engineering Econ professor. 2 1 hour lectures a week plus an hour session with an Indian econ TA who clearly failed the syntax portion of the TOEFL. After miserably failing the first exam, I went to talk with the professor. I though I understood it, but clearly I'd missed the point. Her reply was "Yeah, most first timers fail the first exam. Only the second-time-around students and those with previous classes in TVM pass it...I'm a professor - I profess, I do not teach. You should go talk to your TA if you need help." She was the only prof who taught the course. Ever. B!tch.
BTW - I passed the second test and aced the final to get an A-. B!tch.
I think that's the normal flow of traffic on the 210 west of Pasadena, also.
Of course, in MD the folks on the roller coaster (Ga to Conn ave on the beltay) only seem to do about half this speed, but what makes it impressive is how they do it while eating and talking on the phone while still averaging a dozen lane changes per mile!
The problem is that most people who are passionate about an issue make lousy advocates in front of an adjudicating body. They make arguments which, on slashdot, seem to make sense but which fall woefully short of convincing an "impartial" observer that the law is on their side.
I suppose they could have tried to make the RIAA lawyers prove every penny. Call each witness who dowloaded a track from _his particular machine_ and ask them, under oath, if they would have purchased the CD had the file not been available on _his particular machine_. If they would have downloaded it from another machine, or borrowed it form a dorm-mate, then there was no loss of revenue due to his actions. Of course the amount claimed, per CD, would have to be the wholsale cost of the actual cd. Retail price doesn't count, as you're not required to purchase a CD from an RIAA-member owned store. And, naturally, he should only have to pay half of the cost, and the other half should be borne by the downloading party, of which they now have a record.
Of course, IANAL, so even that probably wouldn't work.
They should have chosen MPEG-9 if they wanted to allow space for two additional compression techs. Everybody knows you have to skip one revision to get a worthwhile upgrade: Cat-3, Cat-5 (nobody used cat 4, and cat 6 doesn't provide a good cost/benefit). MPEG-2 is being supplanted (in some cases) by MPEG-4. Naturally, I wouldn't trust anything labelled MPEG-5, and MPEG-6 will be the next verion to show a noticable difference.
And, of course (must I even mention it) Windows ME?
While I've never taken this to court, I've quoted the law back to certain spammers with results.
I don't get much spam, so when I do I try to nip it in the bud. I received a pr0n site spam a while back. I took a look at the html source and scribbled down the domains. I found about four domains registered by the same fellow, plus two companies. I send a nice letter informing the spammer (both reply-to and the admin contct his domains) that if I didn't receive a reply from his reply-to address that I would consider it to be forged and that he would be inviolation of Virginia law and subject to civil litigation. I also cc's the email to both the corporations - one was a pr0n provider, the other a CC processing service (emails found via whois for the domains).
I never received a reply from the spammer (not gonna drag his butt in for $10), but I received two professional emails - one from each corp. Each indicated that the spammer had violated his terms of service and one (the CC processor) had suspended his account based on my information.
Did he actually get suspended? Who knows. I don't really care, as I've not received another spam from him. That's the results I really wanted (though if it caused him some trouble it wouldn't hurt my feelings).
That's what they are. Pretty standard effect. I'm guessing (from a scan of the article) that they've managed some magic concerning the microchannel interface, but the meat of the "discovery" seems to have been lost in favor of the amazing new heat-pipe phenomenon, which has only been around for thirty years.
Here's an example: http://www.swales.com/products/heatpipes .html
Most multi-sync monitors will already sync to HDTV. My 5 year old, 15", $99 KDS monitor will sync to 720p just fine. It takes a bit of fiddling to get the aspect ratio correct (vertical size against the lower stop), but I get a 16:9 picture and it looks pretty darned good. It just requires a cable to feed the component signal to the rgb lines of the HD15 input connector.
The advantage to this box is that it will transcode component to RGBHV, as well as tune NTSC and allow source switching via remote. Not something I'd pay $400 for. Of course, I did turn my "free" 15" Dell LCD into a TV with their less expensive NTSC unit (~$80) so I could have a TV in my bookcase.
Can we send in an anonymous tip to the BSA that he may have unlicensed software on his computers? I mean, he _might_. Nobody will know 'til he's bee audited by the BSA, right? If he's all legal, he has nothing to fear.
Damn! I knew how were to buy assembler, but didn't have the princly sum of $199 to spend on it. I coded by hand. I never made the machine do much in ML, but it made me understand computers from a whole different perspective.
Then, as a co-op student at NASA I ran into a mathemetician/programmer on a laser-ranging project who did a lot of ML coding by hand in order to squeeze every last byte out of the legacy systems' memory. His favorite story was about a college grad who came in looking for a job. When they asked him which languages he knew, he told them he could program in any language and he asked what language they used. When the m/p told him "machine code," the guy frowned, turned around and left.
Certain types of stone are a good choice. Concrete (plain, or reinforced with large amounts of cover and minimal steel structural contribution) is a good choice. Large hardwood, old growth timebers aren't a bad idea if you're only looking at a couple of centuries.
Here's the key, though: BUILDING CODES SPECIFY LOADS FOR 50 YEAR EVENTS. That's right folks, 50 years. All the loads specified by modern building codes are (generally speaking) designed to a 2% probability of occurance in any given year. Okay, technically that's not 50 years - but you get the idea.
Your design, structurally, should be for a 500 year event. We can extrapolate for those loads, but it is a bot more severe.
Also, build in a seismically stable, non-coastline, non-flooding, low-snow, low rain, low relative humidity locale. Build in the middle of nowhere - nobody cares about the style, and the likelihood of somebody wanting to build a road/powerline/gasline/oil pipline through your house is lower.
Naturally, you should account for two floors plus an unused attic and basement so that you can do repairs & replacement. Make sure you feed everything from your unfinished spaces - nothing in your unaccessible ceiling/floor.
At least, that was my response to seeing Mosaic back in '93. One of the secretaries installed it and showed it to me. Ahe liked it a lot, but I really didn't see the use since there was so little content.
Fast forward about 3 months, and I'd all but left my gopher client behind. In fact, it was later that summer that I figured the web address would replace the 800 number in advertising. Of course, nobody believed me back then. Now it's hard to imagine print or broadcast advertising with it.
Ocean based mining may be expensive, but lunar/interplanetary mining will almost certainly have it beat by orders of magnitude. Yes, working conditions at 300 atmospheres in a corrosive environment causes significant difficulties - more than working in vacuum. But getting equipment to the bottom of the ocean is a good bit easier than getting it into space. And getting ore from the oceans bottom to the surface is (including reentry losses and active guidance) much less expensive and easier than dropping things out of orbit.
But lets face it, lunar mining is just too sexy to pass up.
On the contrary, if you're going to do something in space which causes problems for other countries, you have to undertake "appropriate international consultations." You are not prohibited ro restricted in any way, you're just required to talk about it before you start.
The UN seems to have a resolution enforcement which loosly translates to "Stop! or I'll yell Stop! again."
BTW - how does this affect the folks selling moon real estate?
I would certainly hope that you would store your tapes off-site, why not your backup HDs?
I had nothing but failures on the old (admittedly consumer-grade) tapes I used to use. I back up my personal data to CD now. I really should get better about putting it in the firesafe, though (I think my currents are in my CD binder...on my desk)
A warning about CD-R backups: I've had CD-Rs fail. This was 7 years ago, but we had some gold-colored discs develop "spots" on the written surface, under the plastic. They made the files generally unrecoverable. The degradation occured in a one year timespan. After that, we kicked around the idea of redundant backups and test-reading our old discs once per month just to make sure we didn't lose anything again. Of course, back then our entire department generated only about 150MB of new data each year.
I'm on a small rural co-op telephone system. Since the telco also owns the cable system, I used to say I'd never get broadband, and if I did who knows what it would cost. T1 was quoted somewhat over $1000 line charge, plus service.
After three years of waiting they've installed DSL. I have it. I pay $44/mo for 768/128. ($25 for the "line", $19 for ISP charges)
I spoke with the guy in charge of installing the service, as well as onw or two of the techs (I think they only have three). I'm not really sure if they can make money on it. The CO equipment is mighty expensive, and I suspect my $25 doesn't go very far after debt service on the equipment (which must make two hops - from my NID to the local switch, then through a second switch to their main office).
I paid $99 for my DSL modem and "setup" directly from them, and they included the appropriate cables and two filters, plus about 1 hr of tech time (including travel). They just changed the CO equipment and I needed to get a new modem...so they swapped the new one for the old one - for free. Delivered it right to my door.
As much as I hated waiting to get online, I think I should consider myself lucky. Without competition - real or imagined - my local telco is providing darned good service, for a reasonable fee, with decent support.

Yeah, the stakes are too big. Offer the bounties AND a total monopoly on manned spaceflight for, say, 100 years. Or total exclusive rights to all mining, research, and travel on the moon for the same period. Or exclusive rights to all space-based power schemes.
A couple of billion is chump change. VCs want a ROI in the hundred-fold realm, not the 25-100% perfect-case scenerios that these low figures would offer. That money would be hard pressed to create these systems, much less make them profitable.
I find that Opera has a bear of a time rendering.asp pages properly, and occasionally has problems with java(script). As a result, I'm required from time to time to fire up IE. Unfortuantely, it's usually for "secure" transactions. I've started sending emails to the sites on which I cannot make a purchase/transaction using Opera, telling them that they have lost my business until they remove *.asp pages from their website.
Sometimes I get a response, sometimes I don't. Usually they have no idea that *.asp pages cause problems.
Personally, I don't think I could give up Opera...I've gotten too used to some of the mouse gestures for navigation.

Yikes! Most of these things are bad. Potassium Chlorate is a very bad thing, though. Mixtures with fuel tend to be "sensitive" and - even with a poor fuel such as sugar - can heat to combustion without a flame source.
(reply posted to warn imitators. If you must play with pyro, stick to the Perchlorate version of this oxidizer.)
Have to agree with the AC, as a freshman they need to feel you out a bit. Give you a scare, show you what real work is, weed out the really lazy and really stupid. Even Duke knows that. Come back and tell us how your class is doing when you're a Junior.
This isn't meant to be harsh. There are freshman weed-out classes at nearly every school and in nearly every curriculum. It's the upper classmen who snooze to a 3.5 average that bugs folks.
