Submission + - Sorting Algorithm Breaks Giga-sort Barrier (google.com) 2

An anonymous reader writes: Researchers at the University of Virginia have recently open sourced an algorithm capable of sorting at a rate of one billion (integer) keys per second using a GPU. Although GPUs are often assumed to be poorly suited for algorithms like sorting, their results are several times faster than the best known CPU-based sorting implementations.

Submission + - Duke research experiment disrupts Internet (networkworld.com)

alphadogg writes: An experiment run by Duke University and a European group responsible for managing Internet resources went wrong Friday, disrupting a small percentage of Internet traffic.

The damage could have been far worse however, and the incident shows just how fragile one of the Internet's core protocols really is, security experts say.

The problem started just before 9 a.m. Greenwich Mean Time Friday and lasted less than half an hour. It was kicked off when RIPE NCC (Reseaux IP Europeens Network Coordination Centre) and Duke ran an experiment that involved the Border Gateway Protocol (BGP) — used by routers to know where to send their traffic on the Internet. RIPE started announcing BGP routes that were configured a little differently from normal because they used an experimental data format. RIPE's data was soon passed from router to router on the Internet, and within minutes it became clear that this was causing problems.

That shouldn't have happened on systems that were properly configured to support BGP, wrote RIPE NCC's Erik Romijn in a note http://www.merit.edu/mail.archives/nanog/msg11505.html posted to the NANOG (North American Network Operators Group) discussion list. But nonetheless for a brief period Friday morning, about 1 percent of all the Internet's traffic was affected by the snafu, as routers could not properly process the BGP routes they were being sent.

Operating Systems

Submission + - Demonology '08 (kuro5hin.org)

Guilty Rim Loon writes: "In the new year the Berkeley Software Distribution family of Unix-like operating systems is growing at a phenomenal rate and excitement over the possibilities for this operating system family is in the air. After unprecedented development and adoption as well as major shifts in the marketplace, it's time to take a look at what's new with this demonic family of operating systems. Don't fear, the word demon means Unix goodness at just the right price."

Submission + - Why do people jump to conclusions?

the_B0fh writes: "http://www.kuro5hin.org/story/2007/8/2/15233/84896 claims that Theo accepted lots of $$ from AMD to say bad things about Intel. Theo denies that AMD has given him money. History tells us that Theo has never been reticent about speaking out, even if it hurts his funding (re: Darpa's $2mil grant). So, what is the kuro5hin author basing his opinions on? And why is there a Microsoft link in that page? In the comments section, someone mentioned Matt Dillon's analysis which seems to be in agreement with Theo's analysis. In fact, the only statements I've seen from Linus is only about one of the erratas, and not the others (especially nice things such as second core not obeying the NX bit and so on). Do people just not read and analyze what others say, and blindly accept opinions? Ah, nevermind."
