gozunda writes "My company is an open source software vendor/developer. We maintain a popular open source project and keep ourselves afloat by producing commercial products derived from or extending the value of the core project. Over time we've seen our business model eroding as other open source projects produce free versions of the same extensions and utilities that are our bread and butter. Something that was worth $5K last year is suddenly worth $0 because the free version is just as good as the paid. This same cycle is obviously having an impact on pure-play commercial software vendors. Is open source ultimately a race to zero? In ten years will there be any cost associated with commodity (non-custom) software? If not, will there still be a 'software industry' as it exists today, or will software simply be a by-product of the operation of other industries? Is that a good thing or a bad thing? As a professional developer, do I need to fear this or feed it?"

TRNick writes "How can developers who are working for free protect themselves and avoid getting exploited by business users of Linux? TechRadar has an interview with former Fedora project leader Max Spevack to find out how his new role as manager of the community architecture team is designed to help. Quoting: 'About two-thirds of the Fedora packages are maintained by community people, and if we didn't have that community, that chunk of work would either not get done, which would significantly harm Red Hat's entire value, or would have to made up by more [paid] engineers. The challenge on the flip side of that is to make sure that everyone in the Fedora community feels valued, that everyone who contributes can be proud of the way that Red Hat uses their code.'"

IHateEverybody writes "Scientists have found evidence that the solar wind is ripping off chunks of the Martian atmosphere, which could possibly explain why Mars has such a thin atmosphere today. The chunks are being ripped up along 'magnetic umbrellas,' which are bubbles of magnetic fields which rise from the ground and extend above the Martian atmosphere. This is surprising because scientists previously thought that these magnetic umbrellas protected the Martian atmosphere. Now it looks like exactly the opposite might be true."

Barence writes "Google has launched a new service that allows users to tailor to their own search results. Called SearchWiki, the service allows Google account holders to move results up or off the rankings, or even add their own choice of site to the top of the search results. Google claims that any changes a user makes will only affect their results, and not those of fellow surfers, although it's difficult to believe that some of the feedback generated from the SearchWiki won't be used to fine tune the Google search algorithm. Is this a cunning way to encourage people to sign in while they search, thus providing Google with a richer set of data that can be mapped to specific user accounts?"

gupg writes "NVIDIA announced a new category of supercomputers — the Tesla Personal Supercomputer — a 4 Teraflop desktop for under $10,000. This desktop machine has 4 of the Tesla C1060 GPU computing processors. These GPUs have no graphics out and are used only for computing. Each Tesla GPU has 240 cores and delivers about 1 Teraflop single precision and about 80 Gigaflops double-precision floating point performance. The CPU + GPU is programmed using C with added keywords using a parallel programming model called CUDA. The CUDA C compiler/development toolchain is free to download. There are tons of applications ported to CUDA including Mathematica, LabView, ANSYS Mechanical, and tons of scientific codes from molecular dynamics, quantum chemistry, and electromagnetics; they're listed on CUDA Zone."

tiffanydanica writes "For all the flack Mozilla gets about its new security warnings for https sites, at least it warns the user when a mismatch occurs. Sadly the new Yahoo! Zimbra Desktop (released in part to fix some security issues), doesn't bother validating the SSL certificate on the other side before sending along the username and password, making it vulnerable to a man-in-the-middle attack. This is certainly a step up from transmitting the information in the clear, since the attacker must switch from being passive to active, but with all of the DNS security problems, it would be fairly trivial for a malicious attacker to grab a large number of Yahoo! accounts (be it for phishing or spaming). Hopefully this issue will get fixed shortly, but for now Yahoo! Zimbra Desktop users may wish to use the webmail interface."

DeviceGuru writes "Claiming that service-class robots will one day be pervasive, researchers at the University of the West of England's Bristol Robotics Laboratory (BRL) have begun investigating ways to make robots seem more human. As part of a project to enhance robot/human relationships, BRL has created a robotic head that can exhibit emotions, based on both verbal and non-verbal queues. Check out the videos in the article — especially the slightly creepy one in which the robot contemplates its purpose and its relationship to its environment."

An anonymous reader writes "I'm sure this is something all older Slashdotters are aware of: as I get older my once-sharp brain is, well, getting worse. In particular, I'm not able to remember things as well as I once did. As a geek my capacity in this area was always what defined me as a geek. Nowadays things seem to go in OK, but then leak out. A few weeks later I've mostly forgotten. So, I ask Slashdot: how do you cope with your mind getting older? What's your trick? Fish-oil? Brain Training on the DS? Exercise? Or just trying harder to remember things?"

Ahmed Kamal writes "What happens when you take a solid system such as Ubuntu Hardy, unplug its Linux kernel, and plug in a replacement OpenSolaris kernel? Then you marry Debian's apt-get to Solaris' zfs file-system? What you get is Nexenta Core Platform OS. Let's take Nexenta for a quick spin, installing and configuring this young but promising system."
