alphadogg recommends an article about the rise of Linux on Wall Street. We discussed the beginnings of this trend last year. From NetworkWorld: "Wall Street firms increasingly are buying into Linux, but some still need convincing that open source licensing and support models won't make using the technology more trouble than it's worth. Linux providers, speaking this week at the Securities Industry and Financial Markets Association conference in New York City, stated their cases that Wall Street firms have nothing to fear about diving into open source. Red Hat and Novell argued that's especially true now that specialized Real Time Linux has been developed that meets strict low-latency and messaging requirements of brokerages and trading firms."

superglaze writes in to note that according to Nokia's software chief, its plans for open source include getting developers to accept things like DRM, commercial IP rights, and SIM locks. "Jaaksi admitted that concepts like these 'go against the open-source philosophy,' but said they were necessary components of the current mobile industry. 'Why do we need closed vehicles? We do,' he said. 'Some of these things harm the industry but they're here [as things stand]. These are touchy, emotional issues, but this dialogue is very much needed. As an industry, we plan to use open-source technologies, but we are not yet ready to play by the rules; but this needs to work the other way round too.'"

LinucksGirl writes "Journaling file systems used to be an oddity primarily for research purposes, but today it's the default in Linux. Discover the ideas behind journaling file systems, and learn how they provide better integrity in the face of a power failure or system crash. Learn about the various journaling file systems in use today, and peek into the next generation of journaling file systems."

Bruce Perens writes "Red Hat has settled patent suits with Firestar Software, Inc., Amphion, and Datatern on a patent covering the Object-Relational Database Model, which those companies asserted was used in the jBoss Hibernate package — not in Red Hat Linux. The settlement is said to protect upstream developers and derivative works of the upstream software, thus protecting the overall Open Source community. Full terms of the settlement and patent licenses are not available at this time."

An anonymous reader writes "Phoronix has up an article looking at the release of X Server 1.4.1. This maintenance release for X.Org, which the open-source operating systems depend upon for living in a graphically rich world, comes more than 200 days late and it doesn't even clear the BugZilla release blocker bug. A further indication of problems is that the next major release of X.Org was scheduled to be released in February... then May... and now it's missing with no sign of when a release will occur. There are still more than three dozen outstanding bugs. Also, the forthcoming release (X.Org 7.4) will ship with a slimmer set of features than what was initially planned."

bjcarne writes in to commend Jon Ramvi and his team, who have delivered their first stable release of Ubuntu Eee, an Ubuntu version customized for the Asus Eee PC. "In December Ubuntu Eee started as a one man project, but [over] the last months several people have joined in on the development. We're trying to achieve something which [hasn't] been successful for any other Linux distribution yet: a OS targeting a single computer which includes the best applications available. This means people can buy this really cheap computer and easily get a great OS on it for free. Ubuntu Eee is just for the Asus Eee. Ubuntu Eee is smaller, faster and we're bringing people the cutting edge of technology (while being stable and free of course)."

Anon writes "Mark Shuttleworth provides much more detail today about development of the Ubuntu netbook platform, and says OEMs are calling Canonical when they want to start building netbooks. Channelweb notes: 'It's actually a big deal. For example, Dell CEO Michael Dell has been carrying around an early version of a Dell mini-notebook, and referring to it as the device for the next billion Internet users [...] Asus has become an industry rock star by using GNU Linux to power its Eee PC. HP's niche Mini note runs SLED 10 Linux. The iPhone, of course, doesn't run Microsoft software. Is anyone paying attention in Redmond?'"

prunedude writes "The NY times is reporting that an American military supercomputer, assembled from components originally designed for video game machines, is more than twice as fast as the previous fastest supercomputer, the I.B.M. BlueGene/L. To put the performance of the machine in perspective, Thomas P. D'Agostino, the administrator of the National Nuclear Security Administration, said that if all six billion people on earth used hand calculators and performed calculations 24 hours a day and seven days a week, it would take them 46 years to do what the Roadrunner can in one day."

An anonymous reader writes "In April, the Lonestar supercomputer, a Dell Linux Cluster with 5,840 processors at the Texas Advanced Computing Center in Austin, performed laser surgery on a dog in Houston without the intervention of a surgeon. The article describes the process: 'The treatment itself is broken into four stages: 1) Lonestar instructs the laser to heat the domain with a non-damaging calibration pulse; 2) the thermal MRI acquires baseline images of the heating and cooling of the patient's tissue for model calibration; 3) Lonestar inputs this patient-specific information and recomputes the optimal power profile for the rest of the treatments; and 4) surgery begins, with remote visualizations and evolving predictions continuing throughout the procedure.'"

pbd points out a story discussing the challenges faced by NASA engineers in designing the code sent to operate the Phoenix Mars Lander. Quoting Computerworld: "On Wednesday, engineers sent up the code to run an actual analysis, but a satellite orbiting Mars, which transfers the data down to the Lander, was offline. Robinson explained that the satellite had been hit with radiation, knocking it into safe mode. 'Space is a harsh environment, and sometimes they just go into safe mode,' he noted. 'It's a minor problem. [The satellite] aborts whatever it was doing and waits for future commanding.' Engineers successfully resent the code on Thursday."

MahariBalzitch writes "Popular Mechanics shows step by step guide on how to install Ubuntu Linux on a PlayStation 3 and still keep the PS3 gaming functionality. Now I just need to get my hands on a PS3." Not bad specs for the price, either, since Blu-Ray players still aren't cheap. And though the article calls the procedure "somewhat complicated," it's a lot simpler than was installing Linux from floppies not so many years ago.

KernelPie writes "The Linux hardware site Phoronix.com has announced the release of Phoronix Test Suite 1.0, a Linux-based testing platform designed for benchmarking software and hardware. This suite ships with 57 tests and 23 test suites, which contain everything from open-source games to file encryption to encoding software. In addition, they have a global database where users can submit benchmark results and more — with over 1,000 submissions already. This testing software is licensed under the GPLv3 and is available for download."

geekinchief points to a just-posted interview at Laptop Magazine "with Canonical's market manager, Gerry Carr, where he talks about Ubuntu Netbook Remix. Some interesting details: Canonical does not plan to make the Netbook remix available for download or sale. It will only come pre-installed on new systems. It will boot in 5-10 seconds."

Stony Stevenson writes to tell us IT News is reporting that Acer is betting big on Linux, looking to push Tux on many of their upcoming laptops and netbooks. "The company is already heavily promoting Linux for its low cost ultra-portable netbook range out later this year, but senior staff have said that Acer will also push Linux on its laptops. [...] Acer sees two killer apps with Linux on computers: operation and cost. Its flavour of Linux will boot in 15 seconds compared to minutes for Windows, and the open source operating system can extend battery life from five to seven hours."

eldavojohn writes "There's an interesting post over at the Kernel Trap that focuses on a man's attempt to find out how many one-time contributors Linux averages per release. Although imperfect due to some obvious unavoidable flaws, he got a few dirty numbers of 'never seen from agains' in the commits from patches 2.6.11 through 2.6.25 and the numbers are: {63, 148, 128, 92, 96, 122, 137, 140, 135, 95, 136, 153, 179, 179, 304}. This makes sense as another reader, Greg KH, pointed out that the distribution curve is tilted towards one-hit contributions, 'the distribution of all of our users are: 50% only contributed 1 patch; 25% contributed 2; 12% contributed 3; 6% contributed 4 and so on ...'"

CWmike writes "Steven J. Vaughan-Nichols puts his thumb on what really happened to spur Microsoft's change of mind on sparing Windows XP: The smashing success of Asus and others' Linux-powered UMPCs and mini-notebooks caught Microsoft completely by surprise. It turned out people wanted inexpensive, hard-working Linux laptops rather than overpriced, underpowered Vista PCs. If anyone thought this was a flash in the pan, that Asus just hit it lucky once, they haven't been paying attention. Intel is putting big bucks into its Atom family of processors, which have been designed for UMPCs, or as Intel would have it, MIDs. Intel has encouraged both the computer makers and the Linux companies in its Moblin initiative to run desktop Linux. The Linux companies have picked up on this. Canonical, Ubuntu's dad company, has come up with an UMPC-specific version of Ubuntu 8.04, the latest version of this popular Linux distribution, for Intel Atom UMPCs. At Computex, by my count, more than a dozen new UMPCs were announced both from vendors you've never heard of and from big name companies like Acer and Asus. You can also expect to see Dell releasing its 'mini-Inspiron' with Ubuntu by June's end."

mstrom writes "Google announced it has ported its Google Desktop Gadgets platform to Linux, making it the first cross-platform [desktop] gadgets framework. In a sign that Google is fully embracing the open source model, it admits the product is not feature-complete and has opened up the code base hosted on Google Code 'to give everyone a chance to tinker with the code powering the gadgets.' According to Google: "Gadget support is not just a single feature, but rather an entire platform for miniature applications.'"

We're catching up on two stories of municipal engagement with open source software: Munich (which decided to go OS in 2003) and Vienna (2005). E5Rebel brings us news that Munich has stayed the course. But bkingaut informs that Vienna has decided to migrate back to Windows (Google translation) — to Vista no less. The migration of 720 computers used in kindergartens will cost the city about €8M. The given reason for all this is a language test application for the kids that only works with MS IE and won't be made compatible (by the producer) with Firefox until 2009.

madgreek writes "Last year I wrote of my switch from XP to Ubuntu at work. Now a year later, I am back to reflect on one year of being extremely productive at work using (almost) nothing but open source software in a Microsoft world."

davidmwilliams writes "Whether it was to your taste or not, there's no denying the ASUS Eee Linux subnotebook was a massive sales success. Demand far exceeded initial production so it's not surprising competitor models are on their way. Just like the Eee, the Elonex achieves cost savings by bundling freely redistributable open source software including, of course, the Linux operating system (specifically, Linos 2.6.21). Those who use the Elonex ONE may well understand it uses something called Linux under the hood, but they don't really have to grasp what this means. They don't have to care that the WiFi hardware was carefully chosen to be one of the exclusive few which has supported Linux drivers. They don't need to tamper with the way their family computer is already set up."
