The SR-71 was supersonic, not hypersonic. Hypersonic speeds start about (not exactly) at Mach 5, the speed at which the shockwaves become merged with boundary layer airflow.
Yes. It is easy for all of us on slashdot to sit back and think "My, how stupid all those world leaders are. Diplomacy is failing because they're not smart like us". In the real world, people do not always agree, and diplomacy does not always work, despite what your grade school teachers might have said.
Aerospike engines have nothing to do with hypersonic aircraft programs. Aerospike engines are important for their efficient exhaust plume that is created without a nozzle, hypersonic propulsion usually involves some sort of ramjet or scramjet. The X-33 was not military in any way, it was intended as a space shuttle replacement. You'll notice that the hypersonic aircraft look sleak and pointy, while the X-33 looks like a flying piece of pie with a blut nose. Obviously with such drastically different shapes they would have drastically different performance.
It may have been founded by Thresh, but it is not written nor maintained by him. He left the site a few years ago in fact. None of the site's content is from Thresh anymore (I don't think he even wrote reviews when he was around, I do remember a Half-Life deathmatch guide though).
And in the computer world, I've found traditional qualifications to be often less than accurate when used to judge computer expertise (I've met kids in high schools who know more about hardware than college grad computer enthusiasts). Of course that is not always true, but neither is the opposite case. Which is my point; specs on paper don't always mean much.
Other, more reputable hardware sites: ExtremeTech (broke the story on nVIDIA 3dmark2k3 cheating, uses good benchmarking methods with the GameGauge) FiringSquad (good mainstream site, quicker more casual reading before getting into the really in-depth stuff) ArsTechnica (excellent for info on more fundamental aspects of hardware)
Not to mention the previous THG scandals. Vans, Q3test benchmarks, "nVIDIA approved testing" graphic, TNT2 vs. Voodoo 3 (THG refrained from reviewing the Voodoo5 btw)... The list goes on.
THG is visited religiously and exclusively by many computer enthusiasts, though if they cared to venture out beyond THG they'd find out that Mr. Pabst's establishment is and has been very controversial, to say the least.
This easter egg has existed since the Netscape/Mozilla 0.9.x days, but it's still neat. Type "about:mozilla" in the address box and see what comes up...
Try it in IE too. You get something rather cryptic, to say the least... No, I don't know what it means either.
I know exactly what you're talking about with a recovery "save tabs" feature like the one present in Opera. In Mozilla, I've usually found viewing the History sufficient for re-visiting sites that I was at before a Mozilla crash.
I have experienced your problem #2 many, many times. It seems like Mozilla is going into some alternate keyboard shortcut mode or something. When the arrow and page nav keys don't work, I can press "a" and my bookmarked site which starts with the letter "a" will immediately start loading. After that, all my keys work normally.
Yes, the story author's prices were about $50-$100 above what they actually cost when purchased from a reasonable retailed (i.e. newegg, gameve etc.). The Abit IC7, regarded as one of the top i875 boards, can be found for $135. The IS7, an excellent i865 mobo can be found for about $100.
P.S. This isn't a troll, but it seems that as much as most slashdotters know about linux, coding, and the like, they often seem to be a bit off on computer hardware. Of course they're by all means computer-literate, but their hardware knowledge seems a bit out of date or blended with assumption.
SpamBayes is great if you're a Cloudmark Spamnet refugee like me, who left Spamnet after it went subscription. You probably have a folder full of hundreds of pieces of spam from Spamnet. SpamBayes can be trained on that folder of spam, so it can start accurately identifying spam without further weeks of training, unlike other Bayesian filtering solutions.
The G5 will be available on September 1st. The Athlon64 will be available in the same month. With both processors purported to bring 64 bit to the desktop, it would seem the Athlon 64 would be more appropriate to compete with rather than the Xeon.
I won't use a Mac as long as it doesn't run the software that I use. VirtualPC has no support for 3d acceleration, so that rules out every 3d modeling application and 3d game.
That's right. In the REAL WORLD, companies use Intel-optimized compilers for PC applications and Mac-optimized compilers for Mac applications. That is what they should have done here.
A level ground may be useful for comparing theoretical performance of the CPU's; unfortunately though, we do not live in a theoretical software world.
Apple calls it "the world's fastest personal computer". Mac users say that it is a "workstation", so you have to compare it to Xeon processor PC's. Which one is it? Or is it both, making G5-P4 comparisons perfectly acceptable (price v. performance wise)?
So right from the start the G5 is seriously crippled in these tests. Especially if they don't even take advantage of 64-bit as seems to be the case. Now, on the the other points that the spl dude makes.
The PPC970 is not "seriously crippled" in running 32bit real world apps, so why should it be "seriously cripped" running a 32bit benchmark? Certainly Apple does not feel that it is "crippled" running 32bit, as they would have no doubt mentioned it alongside the benchmarks. Intel would have done the same if trying to advertise an Itanium.
It could be that hyperthreading actually reduced the scores of these tests.
Unlikely, but I have just as much evidence as you.
I'm no expert on the SPEC tests and hyperthreading, but what I do know is that hyperthreading is an intelligent technology. It can't always increase speed, it depends on what kind of code it's running.
HT is intelligent, because it doesn't always work? Yes, obviously it depends on what code is running-- the code must be multi-threaded, like anything intended for multiple CPU's. Or, a single threaded application could be running on top of a multi-threaded OS, in which the OS could divvy up OS/application processing resources for best performance.
At anyrate[sic], the tests were a LOT more fair than the dpl guy makes them out.
Why?
And considering that the G5 could be seriously crippled by not running 64-bit and who knows what other optimisatoins[sic], I'd say that the numbers are still impressive.
And considering that the Xeon/P4 could be seriously crippled by not running HT and who knows what other optimizations, I'd say that the numbers are still impressive.
I wouldn't be too sure about the Photoshop benchmarks. I have seen PC's performing better than Macs and vice versa in tests. It would seem that the wide variety of tools and filters utilize different CPU's in different ways. Wanting to make the Mac look better, a person could have a set of the faster-on-Mac filters run multiple times, increasing the apparent speed difference between Macs and PC's. The same could be said about portraying PC's as faster.

Your post sounds like a troll, but your past posts seem to imply otherwise. Anyway, I'll bite.
"How can an organization continue to release code that has not been tested to comply with four digit dates?"
Everytime Mozilla has been used since 2000 has been a test. So far, for the thousands of people using Netscape 6+ and Mozilla, it's worked fine.
"This seems like a disaster waiting to happen."
The hyperbole in this statement needs no explanation.
Xeon? Bah. Get some Opteron 240s for $290 each.

Thank you. You have raised my impression of Mac users significantly.

That aren't on Macs, of course.

I think by "CAD packages" he meant "CAD software packages".

OS X is just too good. Linux still is hard to use and has a long way to go. OS X is a mature desktop OS.
