Is Your GPS Naive? 291

Posted by CmdrTaco from the what's-a-dikfor-anyway dept.
mi writes "Many GPS devices today will try to scan the FM bands for traffic advisories in the area to display on their screens. The signals, however, are neither authenticated nor encrypted, and one can — with commonly available electronics — construct a device to broadcast bogus advisories. Possible codes range from "bullfight ahead" to "terrorist attack"..."

Submission + - Oldest math problem (prime numbers) solved

Submitted by
Kibbles5757
Kibbles5757 writes: "Independent scientist James McCanney has solved the prime number problem using a rigorous 7-part mathematical proof. The proof includes six of the main properties of prime numbers: symmetry, reciprocity, closure (using the operation of addition) and the infinite wavelike nature of prime numbers. Seven pieces of the puzzle had to be put together in an intricate, interwoven pattern. These provided the solution to directly calculate the prime numbers. McCanney claims that only the most sophisticated mathematicians will be able to pick up the rigorous proof and understand it on first reading. He says there is an overall pattern to the prime numbers and that the prime numbers are not random. They are in fact extremely orderly; one just has to find that order, an order that is "locked in the numbers".

Submission + - Music formats and the future

Submitted by
dheera
dheera writes: "In digitizing my CD albums to my computer for personal use on portable devices, I'm debating whether I should encode them to MP3 or Ogg format. While I support patent-free formats and have a feeling that Ogg sounds better at a given bitrate, I fear that in the long-run, Vorbis will be forgotten, especially now that very few hardware players natively support it, and that my entire collection will have to be re-digitized to MP3 or some other format too soon. What do you recommend — will Ogg Vorbis continue to hold up and will it continue to be an accessible format for, say, the next 10 years?"

Feed Dell Tablet PC coming this Fall? (engadget.com)

From feed by engfeed

Filed under: Tablet PCs

We've been hearing rumors about a possible Dell Tablet PC pretty much since the day the first Tablet PCs went on sale, is it finally going to happen now? None of this is officially confirmed or anything, but jkOnTheRun (which has tons of cred when it comes to this stuff) reports that Dell is probably going to roll out a Tablet PC sometime around September or October of this year and that it will most likely be a convertible-style Tablet based on the Latitude D420 and come with a widescreen display and optional WWAN.

Journal Journal: "Use a non-broken toolchain"

Journal by Elliot_Lin
OK, Here goes for another rant. When my GCC throws an error, and I mention it to the devs, it is immediately my 'toolchain's fault'. OK, maybe my tool chain has been compiled by someone different than the original devs... but I am pretty sure that the Debian devs do not spend their time manually tinkering with the tool chain so as to break it. An error in compiling is an error in compiling. No difference whether its Ubuntu, Debian, Gentoo, Familiar, DSL, Windows, Mac OS X, BeOS, Haiku or whateve

The Completely Fair Scheduler 292

Posted by CmdrTaco from the i'm-always-late dept.
hichetu writes "Kernel trap has a nice summary of what is going on behind the scenes to change the Linux Scheduler. The O(1) Linux scheduler is going to be changed so that it is fair to interactive tasks. You will be surprised to know that O(1) is really too good not to have any side-effects on fairness to all tasks."

Submission + - Sun converts carbon dioxide into fuel

Submitted by
Roland Piquepaille
Roland Piquepaille writes: "We all know that the increasing concentration of carbon dioxide in the atmosphere has a major impact on the Earth climate. But now, chemists at the University of California at San Diego (UCSD) have developed "a device that can capture energy from the sun, convert it to electrical energy and split carbon dioxide into carbon monoxide and oxygen." As carbon monoxide can easily be converted to liquid fuel, this prototype device kills two birds with one stone: it helps saving fuel while reducing the concentration of a greenhouse gas. Still, this device needs some improvements before an industrial deployment. Read more for additional references and a picture of the prototype device."

Submission + - Porn site hacked as an act of Jihad?

Submitted by
LoLo
LoLo writes: "On Easter Sunday, the media servers of a fairly popular porn site (yet another YouTube clone) were compromised. After gaining FTP access the intruder(s) deleted over 7500 videos. All that was left on each box was a new index.html page entitled STOP PORNO with the text "In the name of Allah, Most Gracious, Most Merciful" and a Muslim Prayer Call video embedded in the body. Whether this porn site hack was actually the work of Muslim extremists or a pasty white kid from Philly is debatable. Considering the rash of such attacks over the Mohammed cartoons out of Denmark last year, I think it may have been the real deal."
