An anonymous reader writes "Bjarne Stroustrup, the creative force behind one of the most widely used and successful programming languages — C++ — is featured in an in-depth 8-page interview where he reveals everything programmers and software engineers should know about C++; its history, what it was intended to do, where it is at now, and of course what all good code-writers should think about when using the language he created."

An anonymous reader writes "The author developed a program to snapshot memory usage per process every 3 seconds on Windows. Using this he recorded 3 hours of memory usage for five different browsers under real-world usage scenarios: Safari 3.1, Firefox 3, Flock 1.2 (a browser based on Firefox 2), Opera 9.5, and Internet Explorer 8. A million data points indicate that Firefox 3 has a surprising advantage over the other browsers tested. These are real-world tests and not contrived benchmarks."

cathector sends along a story from SpaceWeather.com on the discovery of water ice on Mars. "Scientists have figured out the mysterious white substance unearthed by NASA's Phoenix lander on Mars. It's frozen water. The breakthrough came last week when Phoenix's stereo camera caught the substance in the act of disappearing. Bathed in martian sunlight for four days, the white substance sublimated — i.e., it transformed from solid to gas without passing through the liquid state. This is how water behaves on Mars.... Some readers have asked, how do we know the white substance is not frozen CO2 (dry ice) instead of frozen water? Answer: Phoenix's landing site is too warm for dry ice. The average daily temperature is about -70 F while dry ice requires temperatures lower than about -109 F." The animated GIF showing the ice sublimating is pretty nice too.

We discussed the Galaxy Zoo project soon after it launched last summer. Science News is now following developments about an odd celestial object that is fueling a lot of excitement among astronomers around the world. In August, a Dutch schoolteacher named Hanny, in the process of characterizing galaxy images, noticed a peculiar object and posted a query about it on the Galaxy Zoo blog. She called it a "Voorwerp," which Science News says is Dutch for "thing" but which Google translates as "subject." Hanny's Voorwerp emits mostly green light (the earlier report said blue). The best guess astronomers have now is that the Voorwerp is emitting "ghost light," i.e. it is "lit by the ultraviolet light and X-rays from a quasar that has vanished in the last 100,000 years," to quote astronomer Bill Keel. "As far as we can tell, it's an unprecedented thing," Keel added. Researchers are scrambling to book time on the Hubble and other major telescopes to get a closer look.

David Pogue comments on the pilot in the wake of his own recent dustup about ebooks and piracy, covered previously on Slashdot."

MojoKid brings news from HotHardware that NVIDIA will be enabling PhysX for some of its newest graphics cards in an upcoming driver release. Support for the full GeForce 8/9 line will be added gradually. NVIDIA acquired PhysX creator AGEIA earlier this year.

schliz writes to tell us that researchers at the University of California San Diego are developing new transistors based on particles called 'excitons' in an attempt to speed up the interaction between computing and communications signals. "Excitons are formed by linking a negatively-charged electron with a positively-charged 'hole'. An exciton decays when the electron and hole combine, emitting a flash of light in the process. By joining exciton-based transistors to form several types of switches, the UCSD physicists were able to achieve switching times on the order of 200 picoseconds."

Elektroschock writes "At a Red Hat retrospective panel on the ODF vs. OOXML struggle panel, a Microsoft representative, Stuart McKee, admitted that ODF had 'clearly won.' The Redmond company is going to add native support of ODF 1.1 with its Office 2007 service pack 2. Its yet unpublished format ISO OOXML will not be supported before the release of the next Office generation. Whether or not OOXML ever gets published is an open question after four national bodies appealed the ISO decision."

Michael writes "Back in September AMD had announced a new ATI Linux driver as well as opening up their GPU specifications, and today they have taken an additional step to better support the Linux OS. With the just-announced Radeon HD 4850 RV770 they have provided same-day Linux support, and the Linux driver is now shipping alongside the Windows driver on their product CDs. In addition, they are encouraging their AIB partners to showcase Tux on the product packaging as a sign of Linux support. Last but certainly not least, AMD is committed from top-to-bottom product support on Linux and they will be introducing high-end features in their Linux driver such as MultiGPU CrossFire technology. Phoronix has a run-down on AMD's evolutionary leap in Linux support along with information on the open-source support for the RV770 GPU."

Nate D writes "It's here: a new major release of Novell's community-supported distro is now available, and can be downloaded from the mirrors. Linux Format has a hands-on look at the new installer, SLAB menu and Compiz Fusion, and weighs up whether the distro can fight competition from Ubuntu and Fedora. Is this the start of a new era for SUSE?"

zorro6 writes "I thought this might be an interesting question/topic and it would sure help me to get some kind of answer. I recently got internet service from a small, local wireless ISP in my area (south central Colorado, USA). The strange thing is that many, many web sites think I am in Quebec, Canada when I use the service. Evidently some geolocation service thinks my IP address indicates I am in Canada. I have checked the obvious. The WHOIS information for my IP correctly indicates a location of Durango, CO. So the bad info is coming from some more sophisticated geolocation service. My ISP is at a loss as to how to fix this but it is causing me a lot of grief. Many of the ads I get shown on Yahoo! for instance are in French! Certain sites won't sell me goods or services because they don't do business in Canada. So far I know that Yahoo! (or their ad provider), Nvidia, Movielink, etc. all think I am in Canada. I would sure appreciate any help/info on how to get this corrected."

An anonymous reader writes "Using data generated by the Mozilla Firefox download pledge page, the map on this blog post ranks countries, not by absolute number of pledges made, but rather on a per capita basis. This analysis yields some interesting conclusions about where open source is strongest and weakest." Anonymous Warthog writes "That didn't take long. In a blog posting from the TippingPoint DVLabs security team (of Kraken and CanSecWest hacking contest fame), they confirmed that they reported a vulnerability in Firefox 3.0 to Mozilla a mere five hours after it was released. Additionally, there was a posting on the Full Disclosure security mailing list from someone that purports to have another vulnerability in the works as well. In the grand scheme of things, this probably means nothing to the general security of Firefox, but you can be sure the browser zealots on all sides will be watching carefully." Finally, from reader Toreo asesino: "Microsoft have congratulated the Mozilla team by sending them their second cake (minus recipe) to Mozilla's Mountain View headquarters to congratulate them on shipping FireFox 3, which went live right on time last night." Congratulations are indeed due on both the browser and the release process — looks like the Firefox fever (despite some seriously taxed servers) resulted in more than 8 million downloads in 24 hours.

The article also collects some other very interesting bits of computer history.

snydeq writes "China has launched an investigation into whether Microsoft unfairly dominates its software market, according to a state media report. A working committee of China's State Intellectual Property Office is investigating whether Microsoft engaged in discriminatory pricing and will also look at Microsoft's practice of bundling other software programs within its Windows operating system, according to the report. The probe is part of a greater sweep of operating systems and other software developed by multinational companies that cost much more in China than in the U.S. 'On the one hand, global software firms, taking advantage of their monopoly position, set unreasonably high prices for genuine software while on the other hand, they criticise Chinese for poor copyright awareness. This is abnormal,' a source said."
