Some instructions on the x86 hardware have a delay; let's say I'm asking for something from ram or cache. This takes more than one cycle (3 from cache if I remember correctly). On a normal, non hyperthreading processor, the processor sits idle until that memory value comes back.
On a hyperthreading processor, the processor can do an instruction on another process in that time. So a second process can come in and do a couple ADDLs.
It may not make your game run any faster, but if you have something in the background that can complete what it's doing more quickly.
SMP with n processors can theoretically run n instructions in one cycle. Hyperthreading still limits you to one instruction per cycle per processor, but it reduces the number of cycles where the processor does nothing because it's waiting on other hardware.
So for you, it probably isn't worth it. But for some workloads, ie: some servers that are constantly delaying on memory, it can speed secondary processes up
There's good stuff in New England - don't give up on East Coast just yet. I have to say I'm partial though, I'm from Maine. I've skiied in California a few times and just loved it.
I just bought a Dell 1701 FP (17" LCD). I had a Samsung 955DF (19" CRT). I was planning on running a dual monitor setup, but I realized how horrible the CRT was next to the LCD and sold the CRT. The CRT lacked crispness and brightness. I didn't even want to just have my playlist on the second monitor. Granted, the monitor was 2 years old and I didn't have it on the highest resolution.
If you stare at a $500 monitor for 4 hours a day, 365 days a year, for 2 years, it costs $.17 an hour. The difference is amazing.
Too bad CMU rolled their vehicle on March 4th. At this point I'm not sure if they're still the favorites. I sure hope so, I have a couple friends on the team.
They lost a significant amount of their equipment when it rolled, including a quarter million dollar gimbal
For more info on their roll, check out their race log
Carnegie Mellon. A professor threatened to fail my ex girlfriend on an assignment last year because somehow turnitin.com didn't work for her, but she didn't know, and it didn't submit. He wasn't all that willing to let her submit it to the site after the deadline and not punish her, even though she gave him a hard copy on time (as did everyone else in the class)
The reason 25 10 5 and 1 works is because the greedy algorithm for giving change is the algorithm that gives back the least number of coins.
What I am saying is that giving the largest amount back of the highest coin produces the least number of coins. For a given amount, give the highest denomination, subtract that from the total to return, and repeat.
If you work with coins in 25 , 12 , 10, 5, and 1 cent quantities, then the greedy algorithm for giving change fails. for example, the greedy algorithm for 21 cents gives a 12 cent peice, a 5 cent, and 4 pennies for 6 total coins. The least number of coins returned should be 3, two dimes and a penny.
Dynamic programming is used for the proper way to give change efficiently in these cases, but I doubt that people can do that in their head. I certainly can't, and I know what dynamic programming is!
I'm sorry, but how is this "stuff that matters?" Come on guys, slashdot is about tech news. I can stand a little news about the Matrix or random movie X sometimes when it has to do with technology, but I think that a post about which character is returning to what show shows the decline of quality choices for slashdot's front page.
feel free to flame away, but posting news about buffy the vampire slayer makes me want to stop reading slashdot.

I found this while reading some biographies after I saw the movie. I realized how much was left out, but I also see how much Nash can speak to me, to other nerds or geniuses who feel that they are crazy.
I have been challenged by the computer teacher at my school to hack the webpage, as long as i tell him and don't do damage. I know he's being serious, so why is it unreasonable for another kid to think the same thing when challenged? The kid did the right thing: hack on but one computer, and then tell the proper authorities that it has been done. The kid did the right thing, followed hacker ethics, and was still punished. I think this is another example of mass paranoia of hackers brought on by media sensationalism of crackers. Unfortunatly, the feds are trying to pass laws, or already have, to prevent white hat hacking. This is becoming like 1984: even thoughts of resistance are being punished.
Napster (Shawn Fanning anway) says buy more CD's, not fewer, to prove that Napster doesn't cut into record sales, and also to show support for the artists. Boycott the RIAA if you want, but somehow support the artists.
In the beginning, or early 1990's, the companies claimed that they charged more for CD's because of the increased price of manufacturin.g And no one cared, because it was a new technology. but with the advent of cheap players, and the digital generation, people could afford the CD's and put up with the price because of the increased quality over Cassettes. Now, it cost 1 dollar for them to make a CD. Then they pay the artist $ 0.55 for each CD sold.
I'd be perfectly happy paying the same price if the artist got a better share. Then again, I have a local record shop that I can buy new CD's for 12.99 a disc.
Slashdot just went for about 5 minutes. Sensationalism, then hypocrisy?
win2k is better under a load than nt 4.0. I use win2k at work, at an asp programming job, and i find that the win2k server crashes less frequently and is a bit faster.
Apache is a great web server. But the fact is it's not as fast as win2k with iis, as proven by some impartial surveys, nevermind the mindcraft one. Even companies who do mostly linux and test the servers can't get apache to server more quickly.
I preordered The Matix with soundtrack from reel.com back in early October. It was supposed to ship on December seventh, but didn't. I called them and they said they had no clue when it would ship. It shipped last Sunday, the 19th, but did not arrive yesterday. My problems with reel, and I suspect any company could have these problems, are that the service representatives wouldn't or couldn't find out when the movie would ship, and the fact I ordered in October, far ahead of the release, and they couldn't get enough from their supplier ahead of time.
Thankfully the purchase wasn't a Christmas presant. I bought it for myself.

Plus, on icy Pennylvania hills, you can adjust the player on the lift after your 30 second ride downhill.

Actually, they wanted to build an academic building there already. Check out the Master Plan.
It's the tan outline (for new) on page 19 of the pdf (labeled 15), south of the main road (Forbes Ave) right in the center.
So his gift is, in fact, helpful.
You went to Carnegie Mellon, didn't you?

but what it does mean is that we must find another way to make it happen.
One of the sins that we get into is saying that something can't happen because it can't happen in the only way we can imagine it happening.
From a lecture by Stephen Rudich
So yeah, maybe it can't happen the way they are talking about, but there's bound to be another way.
Don't say impossible too early...

Who... does... number... two... work... for?
That's right buddy, you show that turd who's boss.
I have seen episodes. hence why i think it's lame.
There are some TV show posts I want to see. ones with technical issues, like discussing the tech of CSI or the special effects on other shows.
but i'd still be annoyed if slashdot posted that the secondary character on CSI was leaving or returning.
I come to slash for tech/sci/geek appropriate information. The geek appropriate information is a stretch here.
I'm sorry, but how is this "stuff that matters?" Come on guys, slashdot is about tech news.

Does anyone purchase cassettes anymore anyway?

there's apache for a lot of OS's, including macOS and OS 2. So, it's not strange to see Apache somewhere other than linux/bsd/unix variants.
Actually, I've heard that the number of slashdotters is past a half million.
