Well, as long as I'm here, let's do some calculations. The article says the black hole's mass is 3 billion times that of our Sun, so multiply 3 km by 3 billion and you get 3 km * 3*10^9 = 9 billion km.
WTF? Mass varies as the cube of the radius, so the radius must be multiplied by the cube root of 3 billion, which is about 1440. So the size of the black hole is about 4300 km.
I think a project of ANY size benefits from peer review, and that it is even more important if there is only a single developer!
Maybe my question was not quite clear. I didn't mean how big should a project be for peer review to be benificial. I meant how big should a project be so that it gets any peer review at all in the first place. In particular, I was asking about the thousands of OSS projects that have between 1 and 5 developers. Do these get any significant amount of patches/bugfixes to justify their being open source?
Number of Linux Distributions Surpasses Number of Users
Somewhere in California - At 8:30 PDT with the release of Snoopy Linux 2.1, Goober Linux 1.0, and Yellow Dog Linux 3.0, the number of Linux distributions finally surpassed the number of actual Linux users.
"We've been expecting it for some time," Merrill Lynch technology analyst Tom Shayes said, "but this is a little sooner than most expected. We've seen explosive growth in the number of Linux distributions, in fact my nephew just put out LittleLinux Chart Tommy Linux 1.1 last week."
Long time Linux guru Bob Tallman said, "This is great for the open source movement. I have 7 different versions installed on my computer at home. Some guys I know have over 30."
Microsoft CEO, Steve Ballmer said, "Microsoft will have to play catch up with the number of versions that Linux has, but we think we can do it. With the break up of Microsoft imminent that will instantly double the number of Windows versions available."
Microsoft also announced the release of Pocket PC for Workgroups, Windows GT special edition and Windows 2000 - the Director's Cut with special code added by Bill Gates himself that wasn't in the original release.

Personally, I don't like online books too much. I'd rather be able to kick back and drink a beer and read. Can't do that with a 19" CRT.
But you can't use the code snippets directly from a paper book. And dead trees can't be grepped.

Of course, the article also points out that the exact material has yet to be made...
You're missing something here: the difference between science and engineering. Space elevator advocates often point out that most of the remaining problems are not in the realm of science but instead tech and financing. So progress is not dependent on some long haired genius in a basement lab having a brainwave. You can make confident predictions that technology will improve and that the material with the required tensile strength will be constructed soon in the future. And hey, considering that these guys are trying to accomplish the mind-boggling, optimism is the only way.
Re:A bzip2 version would be nice ...

Gzip on a PCI card

No, bzip2 is something that won't work for applications like serving web pages.
gzip works with streams, producing input as it gets output. OTOH bzip2 treats the input as blocks. Thus it needs to get a whole block before it produces any output. Similarly the client needs to get a whole block of data before it can even start rendering the page. The man page of bzip2 says that the default block size is 900,000 (!) bytes. So while using bzip2 may improve bandwidth it will result in large latency.
gzip was designed with such considerations in mind. Throughput of the algorithm took precedence over compression level. Good to see their farsightedness paying off. And the algorithm is pretty simple so that it can be implemented in hardware directly.
Another thing about gzip is that it is assymmetric: decompression is much faster than compression. Again this is a nice feature, because most files will be decompressed many times but compressed only once. Thus for instance, all man pages are stored in gzipped form and decompressed on demand.
But I can't see the point of implementing it in a PCI card. Wouldn't it be better to integrate it with either the processor or the network interface?
He has made a profound point in so few words. There can be no excuse for/.ers for not reading this article.
I just want to make the observation that in real life you don't get to choose your threat, of course; both threat models are present to some extent. You can only talk about which threat model $protection_measure addresses and to what extent.
Another thing is that *AA can hope to bring the Napster model closer to the small-scale copying model by persecuting individual users. Witness:
The first, which I'll call the Napsterization model, assumes that there are many people, some of them technically skilled, who want to redistribute your work via peer-to-peer networks; and it assumes further that once your content appears on a p2p network, there is no stopping these people from infringing.
On most p2p networks there is no anonymity and so there is still a chance of preventing this scenario. But all that changes when freenet comes into the picture. If it gets widely used, an ugly, long-drawn, bloody clash between "content creators" and "pirates" is inevitable. There are two possible outcomes at the end of it: 1) a draconian world ruled by the evil side 2) a severe reevaluation of our current notions on copyright, intellectual property, and revenue models. I dearly hope the clash occurs and the latter outcome results. The sooner we get out of the digital dark age the better.
the DoD moved their GPS systems to windows, which was so buggy that accuracy dropped to 100 meters from 3 meters. In order to cover it up, they claimed they are doing it because of the war;)
This problem happens even during updatedb (locate's database). Perhaps there is a way of specifying the maximum number of memory pages that can be used for caching disk blocks?
small copper 'wicks' to transport methanol... from one area of a computer to another where it can be dispersed more efficiently, comfortably and compactly
I hope they can extend their technique to ethanol. And make it work for humans. Then we'll have a killer.
I'm from India. I've got a couple of observations.
You're right about the problem not being with textbooks. The textbooks here are as dull if not duller than anywhere else. But smart is sexy over here. There's a lot of motivation for students to learn. And there's the economic incentive, too. Very hard to get a job that pays enough.
That's not the whole picture, though. There are government schools and private schools. What I said above goes for the private schools. In the government schools kids go there because they have to.
Then why the stereotype about smart Asian kids? Simple. The smarter kids get a job/fellowship in the U.S and migrate there, which is the only section you see.

WTF? Mass varies as the cube of the radius, so the radius must be multiplied by the cube root of 3 billion, which is about 1440. So the size of the black hole is about 4300 km.
Now, if someone would write a tool to produce a 3D tour of slashdot stories ... maybe that would help spotting the dupes ;)
Now if this idea takes off, and is adopted even outside the realm of book publishing, the world will be a much better place.
Actually its more confusing than that. Gigabit usually refers to 10^9 bits, while gigabyte is usually 2^30 bytes (1.074 * 10^9 bytes).
So it's the Blue Screen of Death for all the ReplayTV's out there?
