Well, it's actually only twice as heavy on a volume basis. (Hydrogen gas is H2) And the number of molecules of a gas in a given volume (and temperature) is constant (to a first order approximation) regardless of which gas is being measured.
In this house, we obey the laws of thermodynamics.
Those sages words of Homer Simpson certainly ring true here. By most definitions of hot, if the water is hot, it is therefore at a higher temperature than the rest of the surrounding system. According to one of the laws of thermodynamics, the water will lose energy to the rest of the temperature such that the system reaches equalibrium (assuming of course a hot water heater does not inject additional energy). If the system is the universe, this endpoint is the heat death of the universe. If this system is your bathtub, this endpoint is either where you add more hot water or get out of the tub.
Keep in mind, a lot of areas have enough blood for the time being, but the length of time blood is viable is less than the length of time between when people can give blood. Because of this, some areas are encouraging people to wait a little while so that there isn't a shortage down the road when everyone who can give blood has already done so and therefore can't until their body replaces the blood they gave.
Umm... from my arch. class, von Neumann was defined as having memory and data using the same bus, versus Harvard architecture, where separate buses are used. Intel chips are von Neumann; at least some RISC archs (don't know about personal computing ones, but some embedded cards for sure) are Harvard, since the separate buses allow you to have 8 or 16 bit data, and use fewer bits to store an instruction. As an added bonus, something like a buffer overrun can corrupt data, but because instructions can be made read only, you can overwrite the stackpointer and get it to run the program from other data you used to overrun that stack.
At any rate, I agree with your underlying premise, but it's Friday night and my plans got messed up, so I'm going to quibble. To further quibble... a washing machine has memory (even if it's a 2 bit state table of "washing, rinsing, shaking, off), and certainly has i/o (button pressed, coins received etc.) Actually, let me clarify... some washing machines have these... I'd be willing to guess most of the machines I've used in the last 6 years, except when I was at home, were mechanical based, but newer washing machines have some smahts.
Hmm... I had the apple iie version. I guess I'm not quite as old school as I thought. The downside of having to walk and aim being that half the time you started in some corner surrounded by trees that stopped all bullets entering the rectangular shape around the tree and by the time you walked out of there, several deer/bear/buffalo had ambled by the top of the screen.
I'm curious... did the people who did it just for the hunting use that funky square array of keys? I would normally use the arrows; never could get the hang of the other layout (that let you rotate quicker I think). Of course, thanks to Nethack, I'm now pretty proficient with vi's funky layout.
Comment on #2, just in case someone's still reading this thread:
A) SUN blade can take more or less standard PC100 memory, meaning it's stupid to buy anymore than the minimum from Sun
B) The PC card is neat, but the memory is not your run of the bill PC memory... it's SODimms (a la laptops) and I'm not sure if you can plug in laptop memory or if you're stuck paying Sun for the right stuff
C) Oh, and as far as full speed goes, I've seen the earlier one running remotely (i.e. logging into the sunblade from a linux box and exporting the display, you can now run windows inside an X window.), and I've used it locally. Using it locally, the mouse (emulated) is super jerky; I'm hoping to borrow a second USB mouse and hook it up directly to the PC-card, and hope that fixes it. Running remotely, I didn't notice it being as jerky, but I didn't really get to play around with it; my friend was showing it off (and actually, in the remote case, it was running on an Ultra (10 I think, but maybe >10), not the sunblade.
Well, you might be a troll, but in case you were being serious:
1) She was comparing at 200 digit length moduli. This is slightly smaller than one would want to use for long term security (10^200 is somewhere around 2^640, as opposed to recommended key lengths of 1024 or 2048) As a point of reference, it's generally assumed NSA can factor 512 bit keys fairly readily.
2) Moreover, trying to bruteforce crack even 2^512 is a ridiculous endeavor. Essentially, imagine having a... wait for it... beowolf cluster of beowolf clusters.... i.e. 1 Million clusters of 1 Million computers, each running at a speed sufficient to do 10^12 (terraOps) operations per second. This works out to 10^6 * 10^6 * 10^12 = 10^24 operations per second. To within 1%, pi seconds is a nanocentury. Or, in other words, in century, there are 3.15 (the slightly more accurate value) * 10 ^ 9 seconds. This means that in a century, 3.15 * 10^33 operations can be done, which is roughly 2^112. So in theory (with enough memory to use the meet in the middle attack on triple des), in 100 years, triple des could probably get broken. However, to factor an 512 bit RSA number with brute force, one still has 2^400 centuries to go. This greatly exceeds the expect heat death of the universe, to say nothing of the sun, which should have bit it well before.
Brute force really only works well with symetric ciphers (DES, triple DES, RC5, AES, etc. [and even then, more 'elegant' attacks such as differential cryptoanalysis are more potent in some cases]); with public keys, there are typically more efficient was to attack (Pollard's Rho, Number Field Seives, etc.)
3) There is already an attack against the algorithm; see the postscript of the article.
And I give you my fortune:
Lesser Known Programming Languages: #13 -- SLOBOL
SLOBOL is best known for the speed, or lack of it, of its compiler. Although many compilers allow you to take a coffee break while they compile, SLOBOL compilers allow you to travel to Bolivia to pick the coffee. Forty-three programmers are known to have died of boredom sitting at their terminals while waiting for a SLOBOL program to compile. Weary SLOBOL programmers often turn to a related (but infinitely faster) language, COCAINE.

Unless they're doing something more clever than just reading the HTTP_AGENT variable, how long before someone with Konqueror (or telnet to port 80 or whatever) starts reporting they're either using a Cray 10000 or a Commodore 64 to browse the Web?
Right, just like the ability to determine the angle of reflection of the ball separates the average player from the pong masters. Some people enjoy the fast twitch-type challenge of having to micromanage 100's of units at once. Good for them. Other people are more interested in other strategic aspects.
Out of curiousity, did you try faking your browser information to see if it's something like the Cartoon Network checks to see if you're running Windows, and if you're not, just assumes you can't support Flash? Or is that not the problem you're having?
Whoa... at the risk of feeding some creature, horribly stunted, presumably by a steady diet of mountain dew and ramen noodles
I don't think anyone would cite the start menu as an example of embrace and extend. That would be taking (well, okay stealing) MacOS concepts and adding to them. It doesn't prevent Mac from still doing it's thing. Similarily, when the people making Konqueror decide to take the traditional browser layout (i.e. back/forward/reload and then location toolbar) and add a button to clear the location bar so that you don't have to deal with X-windows vs Windows cut-and-paste semantics, as well as that neat little eye-candy glyph (the one that has a generic logo for most pages, a local logo for local pages, a slashdot picture for slashdot pages, but sadly no bio-hazard or jolly roger symbol for microsoft.com pages), that's taking and adding.
Embracing and extending would be if Konqueror added new html extensions, somehow convinced Apache to support them, and then made sure that they wouldn't work on Internet Explorer, but only doing this after enough people have switched to KDE so that this actually makes a difference.
In short, don't mix two concepts. (And as for the stealing from Mac versus taking from Windows... yeah, there's some room for accusations of hypocrisy, but some differences as well, since copying Mac allowed Microsoft to maintain it's advantages; copying Windows is now seen, sadly, as necessary to convince people to switch, since most people don't want to have to relearn what they're used to)
I was pretty sure that last time I used GNOME, there was an option to turn on a clippy-like thing that sat on top of your windows and was supposed to spout advice to you. Might have been KDE... I forget whether I was using Redhat (in which case GNOME) or Mandrake (in which case KDE)... either way, I didn't work and at any case, I quickly switched back to blackbox.
(Too bad setting my background using xfishtank -c instead of something like xv defeats the low profile aspect; it's certainly more fun to look at.)
1) I thought Apple released a patch to fix IIe's? [Or was the bug that it rolled over on 87 to 84, and now rolls over to 87 in 90,93,96,99,and 02 or something like that?]
I had a IIGS, which as far as I know will outlast the life of the battery used to keep the time (and probably outlast various components... adb was a great idea, except that with the GS at least (and probably the early macs), continually replugging in the cables going in from the keyboard to the mouse and cpu (my left-handed brother liked to make a big deal out of being able to use the mouse with his left hand, which annoyed this piss out of everyone else in the family) caused the gold connections to wear out, causing sporadic faulty connections, causing occasional slow downs from the blazing 2.7 (or whatever... I thought it was 2.1, but someone else claimed it was 2.7...) MHz to about zero... an experience I relived many times when I "upgraded" to a windows 3.11 machine on a 486 dx2.)
2) According to my recollection on battery specs, the apple IIe battery's were only supposed to be good for 5 years. I know if you leave them on, it doesn't drain that battery, so in theory, one could get a few more years out of them. Are you still on the og battery, and if so, have you been running the Apple II's 24/7 for this long? [Calculating PI perhaps?... upstairs in my parents room next to the GS is a fun happy book on things to do with your Apple... that was one of them... too bad it uses one of the slower converging algorithms, but I guess since it's using native math (instead of a big number library), that's probably irrelevant since you'd never be able to get more than a few decimal places of accuracy anyways.)]
I've always been a big fan of the stupidity of man theory: think how dumb the average human is, and then remember that half of them are dumber than that.
I don't know about other companies, but I know at mine, general policy is to turn that off (Netscape's What's Related thingie, to use your elegant technical term). Why? Because to work, it sends every URL I or someone else visits to the server handling the What's Related thingie. At home, I could not care less who knows I visit slashdot.org (note the correct use of that expression, one of my inherited pet peeves), but I can understand why companies might have a problem with this. I can also forsee (unless I misunderstood the implementation) typing in some obscure tla and having some part of XP intrepreting it as something completely different, providing yet another opportunity for me to fight with a Microsoft product over who knows what I meant to type more.
Major Premise: Gcc does less useful optimizations on the sparc platform (than on the x86 platform).
Fact: Sparc is non-X86.
Fact: PPC is non-X86.
Minor Premise: Not well working on one non-X86 platform implies also not working well on another.
Therefore: Gcc does less useful optimizations on the PPC platform.
Is that sufficiently twisted and bizarre?

SETI has, at least as far as I understand it, one advantage with respect to cheaters versus RC5, DES, et al. With SETI, one would hope that there would be more than just one signal of intelligence being captured, so that if someone cheats, claims to have searched a region containing an intelligent signal, but does not, there will still be other intelligent signals to be found elsewhere. In contrast, with DES or RC5, there is only one needle in each haystack, and if a cheater happens to claim the section where the needle actually is, no one will ever find the needle (well, at least until they check the rest of the pile, and then start rechecking sections.)
