Re:Beating plowshares into swords
Of course, anti-matter engines are waaaaaaaay off
Actually, we already have anti-matter engines, they're just not very sophisticated. Pennsylvania State University and NASA are investigating these drives. The drive could power a mission to Mars in 120 days. That's: go to Mars (30 days), stay for 30 days, and come back (30 days). Sum: 120 days. That's awesome.
Ah, here we go:

Re:Overheating indicator
Sure, pure Aluminum might burn, but it's most likely an alloy of some sort.

This is actually the second rocket range in AlaskaThe first rocket range in Alaska is at Poker Flats. Poker Flats hasn't launched any orbital rockets, but they have launched a good many ``sounding rockets'' which carry instrument packages into the upper atmosphere.
The range is operated by the University of Alaska's Geophysical Institute, which studies Space Physics and Aeronomy among other things.
One of the neatest things about having a rocket range affiliated with the University is that students can design and launch a suborbital rocket in the ASRP.

Polar Bear Livers
"Polar bear's liver is poisoned becuase of high quantitys of vitamin D, not vitamin A."
From Emazing Science Facts:
"Polar bear livers have such high levels of vitamin A that they are highly toxic to human beings."
From The Alaska Cooperative Extension:
"While most people do not have a ready source of polar bear liver, it is a well known, even notorious source of vitamin A. That is, vitamin A is toxic marginally above required levels and polar bear liver is exceptionally potent."
From Discovery Online:
"Although the extremely high vitamin A content in this fatty diet would be toxic to humans, the polar bear's liver can process it just fine. (When traditional Eskimo hunters killed a polar bear, they would drop its liver through a hole in the ice so nobody would be tempted to eat it.)"
From The Encyclopedia Britannica:
"The polar bear is sought for its trophy value and (especially by Eskimo) for its hide, tendons, fat, and flesh; the liver, however, is inedible and often poisonous because of its high vitamin A content."
Thank you, drive through. -
Re:I'm trying to pick a Distro and I can't decide
I think Mandrake does a nice job with keeping up to date. Their package manager/update system couldn't be any easier. I've been using Mandrake since 6.0 came out and I haven't been disappointed yet.
If your local mirror is /.d try:
linux0.cs.uaf.edu/pub/mirror/mandrake/7.2/
I've been using 7.2beta for a few months and I haven't had many problems with it. The only hard part is that you should know who really made your monitor although by default it makes a pretty good guess.
Those of you who want to dual boot a Win 9x system shouldn't overlook lnx4win. This will install linux without repartitioning your hard drive. -
Re:Mandrake and KDE2
I'm writing this on Mandrake 7.2beta - its sweet. XFree86 4.0.1, KDE 2, Gnome 1.2
All of it is working now why wait for the end of the month when all the mirrors are hammered. Get it now and update to stable after things quiet down.

Re:Is Kpackage included in this release?
I know its in Mandrake 7.2beta and it works just fine.
If you can't find it anywhere else try:

On gender
Many, many people who have posted on the topic of gender inequality in the last few days have brought up the received wisdom that girls get less attention in school. Read this and then think about it some more.

Re:Computers Omnipotent?
The idea came from outside the industry. You have to remember that the average user doesn't know the limitations of a computer. We in the industry have a good idea. System like Windows and MAc hide all that stuff from the user.
For example, if you were to ask you're average computer user that's not a DBA, programmer, sys admin, etc. the question "can a computer represent all real numbers?" You will probably get and answer of "yes" most of the time. Those of us in the industry know that the answer is no. This problem comes from the method used to hold floating point number on computers. A lot of modern computers use the IEEE floating point notation standard to contain a floating point number in memory. If you look at the example on the page, 17.15 is not really stored as 17.15 (I should note that the example doesn't point this out, but leaves it to the reader to determine by doing that math), the valued stored is 17.1499996185303. This is close enough in most cases, but the problem increase as you go along--especially if you multiply and divide.
Remember, not everybody knows the limitations of computers. I would suspect that all of us might be able to learn at least one thing from the book.
