Ok, I misread the comment. It looks like this may have been hand-written in the library. Nonetheless, this is definitely loop unrolling -- there is a loop and certain parts of it have been written explicitly. Locality in code and data is indeed part of loop unrolling. While most people think that loop unrolling is only for code locality (i.e. to prevent unnecessary branches), data locality as you already mentioned is in fact handed by certain special purpose compilers through loop unrolling.
Some newer VCRs (and therefore probably DVD players) have this feature that allows them to set their time to a time signal on a certain channel, usually public television in the US. The station transmits the time via XDS (extended data services). Maybe you could set up something with a TV card on your time server...
This is kinda weird. Certainly, no new customers (usually corporate/research, i.e. not hackers) would buy a chip that will be discontinued and it looks like HP itself acknowledges that:
AlphaServer systems will be focused on the Alpha installed base. - from the press release sited above.
But this also means that of the existing customers, probably only those who can't find another alternative soon will buy the new Alpha. Seems like kind of a harsh thing to do the Alpha. If they (Compaq) released this chip then said that they were stopping the line, that would be one thing, but in this case, they're stopping the line before releasing the chip! This is certainly a bizarre move.
This sounds to me like a standard compilers loop unrolling optimization. Almost all modern processors run this kind of code faster. Sounds like you had a cool compiler, though the alpha itself is cool for other reasons.
I think the theory behind John Cage's 4'33" is not so much that it's a silent piece, but rather to get the audience to listen to ambient "noise" around them. The music is produced by the environment, not by the piano. You could call it conceptual art. There's a good article here. With this in mind, I wonder what direction the legal case should take...
The song (both versions) is one of my favorites. It's so catchy. I've had it stuck in my head whenever I didn't have another song stuck in my head...;-)
Sauce for the goose is sauce for the gander; anyone can put a backdoor into an OSS program, but anyone can also see it. With closed source, you're trusting that the vendor won't put one in. Of course, now you're assuming that (1) the vendor has no malicious intent and (2) that they keep their code completely safe. Of course, that could never happen...
It's ironic that the article talks about terrorists using these things, so they need to tap fiber. Hasn't it become clear from the news of the last week or so that the FBI, CIA, etc. have plenty of information, they just don't know how to use it?
Lots of other people have mentioned that they want Ogg support on their player and a few others have pointed out the FAQ answer that says it's probably too hard to do on this device. What I would like to see is a portable device that can be easily extended to arbitrary formats. For example, my current audio format of choice is FLAC which has no portable hardware support (though there apparently is a car player that supports it -- rock!). I doubt that it will become very popular though, because it's a lossless codec and therefore must take up more room than lossy codecs. But that's beside the point -- if someone makes a new audio format that is truly cool and does some things that certain people like or want, it would be neat if you could carry around that music without custom hardware.
The best thing about the Kinesis is that the designers realized that the thumb is our strongest digit and moved all of the most frequently used keys to be used by the thumbs. Enter, space, backspace, and delete are all at the thumbs. Escape is too small for us vi users, but that can be remapped.
This paper doesn't say anything new about how these worms work, rather it provides empirical evidence and models on how they spread. All of the information about these worms was already available elsewhere.
As for security through obscurity, look at the target of all of these worms...
Yes, many of you will say "duh!" when it comes to the conclusions of this paper, but what is great about this study is that it provides empirical evidence for the stuff that we've "known" for some time. In particular, look at the graph of Code Red Iv2 traffic. Even after all the hubbub, it comes back every month. Moreover, this paper gives some very good models for showing how these things spread.
Money is the biggest obstacle to all of this. We've had the technology to build a lot of this stuff for a while, just not cheaply. If there's money in it, and a profit margin, then it'll get built. Otherwise, it's just 70's TV-show fodder...
IANAL, so could someone explain why this case is called Eldred v. Ashcroft? Ashcroft wasn't the attorney general when the act was passed. Is it just common practice to use the name of the attorney general when suing for unconstitutionality?
Since it's all free now, there probably won't be any problems except limited bandwidth. But when they go to $20/month, how likely is phreaking to start happening? WLAN authentication hasn't had the best history...
Good points. I think that legislators probably focus on these rare events because they are so rare. They stand out and make the news. "Poor family evicted from home" as a headline doesn't make "good news" because it happens all the time. Signal-to-noise ratios are probably the issue.
If it hasn't shown in your timezone yet, obviously, don't click through.
You guys have some nerve... First you ruin the Lone Gunmen thing, now you tell me what I can and can't do? Oh, yeah? Well, I'll click through anything I like!;-)

oh dear... too... much... hacking...

Is that by weight?

For those of you who missed it, this refers to the Simpsons, 3F23, "You Only Move Twice". SNPP has the episode capsule.

No system is secure in the face of inept admins. OTOH, most commercial operating systems out there can be secured by a good admin.

Just a thought...
First we get RMS wanting us to say GNU/Linux and now we have someone else wanting us to say Win32/Linux? When will the madness end? ;-)

The story is here. As for free vs. $20, it looks like it's free for now and they want to start charging $20 eventually.

Is this a clever RIAA creation?
What an incredibly irresponsible statement. Don't go pointing fingers until you have some evidence.

Nice try, chrisd. Sure we all see that the story appears to be posted by Hemos, but I smell a conspiracy... ;)
