Doug Treadwell writes "Many people have wondered what the difference is between the Computer Science education given in the average public university versus one given in an Ivy League university (or a top level public university). There have also been discussions here on Slashdot about whether any Computer Science curriculum gives students the knowledge they need for the working world. As a computer science student both questions are very important to me, so I decided to answer them for myself and build a website to share what I found. I was able to find the required reading for hundreds of courses at Stanford, Princeton, Carnegie Mellon, and Berkeley; along with some other institutions. This should also help answer some of those 'What should I read?' questions."

Science News has a story of strange bedfellows. It seems that Antarctica was once adjacent to what is now the American Southwest, some 800 million years ago. Earth's continents then formed a supercontinent called Rodinia, predating Pangaea by some 550 million years. "...the ratios of neodymium isotopes in the ancient sediments in the Transantarctic Mountains are the same as those in what was then Laurentia, says Goodge. Also, the hafnium isotope ratios in the 1.44-billion-year-old zircons found in East Antarctica match those of the zircons found in the distinctive granites now found primarily in North America. Finally, the researchers note, the ratios of various isotopes and elements in a basketball-sized chunk of granite found in East Antarctica — a chunk ripped by a glacier from bedrock now smothered by thick ice, the team speculates — match those of granite found only in what was southwestern Laurentia, which today is the American Southwest."

AdamWill writes "The Mandriva Linux 2009 Spring Alpha 2, marking the first public pre-release of the upcoming Mandriva Linux 2009. This alpha introduces several significant changes, most obviously the inclusion of KDE 4 — 4.1 beta 2, specifically — as the default version of KDE, and the latest development version of GNOME, 2.23.4. The kernel has also been updated to release 2.6.26rc7. Another feature of interest to many users will be the addition of orphan package tracking (and optional automatic removal) to the urpmi package manager. Of course, many applications have been updated (although the default version of Mozilla Firefox is still currently 2.0.x), and most of the distribution has been rebuilt with a new GCC version, 4.3. Mandriva warns that this is a true alpha, likely to contain many bugs related to the new version of KDE. Please install it only in a test environment, and especially do not use it as an upgrade from any earlier Mandriva Linux release."

ruphus13 writes "Twitter has had a lot of public woes with Open Source technologies like Ruby on Rails, and a lot of alternatives have sprung up in the micro-blogging world, but no one has managed to dislodge twitter in its usage or appeal. Now, an Open Source alternative by Identi.ca, backed by project Laconica has emerged. From the article, 'It supports OpenID for logins, is completely free software, and is designed to apply a Creative Commons license to all the traffic that it carries. It's also built to support the OpenMicroBlogging protocol, meaning that (at least in theory) it can attack scalability issues by federating together multiple autonomous servers. The underpinnings of Laconica include PHP, PEAR, and XMPP. You can download a tarball of the source, or check it out directly if you're using Darcs (there's also an unofficial mirror on Google Code, giving you Subversion access for a read-only copy).' The community will still need to work on this, if a true competitor to Twitter is to emerge. It is lacking APIs, and SMS integration. Oh, and millions of users!"

Dekortage writes "The NYTimes has a piece up about the paradox of privacy: 'Normally sane people have inconsistent and contradictory impulses and opinions when it comes to their safeguarding their own private information.' More specifically, it's all how you ask: if you don't talk about privacy, people won't worry about it. In one survey, 'When the issue of confidentiality was raised, participants clammed up. For example, 25 percent of the students who were given a strong assurance of confidentiality admitted to having copied someone else's homework. Among those given no assurance of confidentiality, more than half admitted to it.'"

FiReaNGeL writes with an excerpt from a story at e! Science News: "Taking advantage of a unique cosmic configuration, astronomers have measured an effect predicted by Albert Einstein's theory of General Relativity in the extremely strong gravity of a pair of superdense neutron stars. Essentially, the famed physicist's 93-year-old theory passed yet another test. Scientists at McGill University used the National Science Foundation's Robert C. Byrd Green Bank Telescope (GBT) to do a four-year study of a double-star system unlike any other known in the Universe. The system is a pair of neutron stars, both of which are seen as pulsars that emit lighthouse-like beams of radio waves."

Barence writes "The majority of dial-up Internet users say they don't want to upgrade their connection to broadband, according to a new study in the US. The Pew Internet & American Life research found that 62% of dial-up users had no interest in upgrading to a high-speed connection." (CNN is carrying the AP's story on the study, too.)

Slimy anti-virus provider AVG is spamming the internet with deceptive traffic pretending to be Internet Explorer. Essentially, users of the software automatically pre-crawl search results, which is bad, but they do so with an intentionally generic user agent. This is flooding websites with meaningless traffic (on Slashdot, we're seeing them as like 6% of our page traffic now). Best of all, they change their UA to avoid being filtered by websites who are seeing massive increases in bandwidth from worthless robots.

LWATCDR writes "Yes, it looks like Microsoft is going to a rental program for Office. From the article, 'The software bundle, which also includes Microsoft's Live OneCare computer security software, will be sold at nearly 700 Circuit City stores for $70 per year.' Well I for one will be happy to stick with OpenOffice for now. From Microsoft's point of view it means a constant flow of money. For the customer it means you only have to pay a little each year instead of a lot every few years. I don't think this will save the average user any money and I wonder about problems with 'activation.' So will this fly, or will it give a big push to OpenOffice?

Constantine writes "The Linux kernel is one of most complex open source projects. Even though there are a lot of books on the Linux kernel, it is still a difficult subject to comprehend. The interactive Linux kernel map gives you a top-down view of the kernel. You can see the most important layers, functionalities, modules, functions, and calls. Each function on the map is a link to its source code. The map is interactive. You can zoom in and drag around to see details."

ZonkerWilliam sends along a link to a Wired writeup on a novel 3-D holographic display developed at USC. Be sure to watch the video at the bottom of the page. "The process is not simple but can be defined through a few key concepts: Spinning mirrors, high-speed DLP Projections, and very precise math that figures out the correct axial perspective needed for a 360-degree image (even taking into account a viewer's positioning.)"
