Tiemann: Open Source Incentives

jake — 2009-07-03T18:57:39+00:00

Michael Tiemann reports on his recent trip to Brazil for FISL 10. He notes that free software adoption is growing rapidly within the Brazilian government. He also describes an effort by the Malaysian government to reward use of free software, rather than the development of it, because that can lead to multiple, competing solutions that don't necessarily solve the users' problems. In addition, he also noted a barrier to free software adoption: "On the alarm front, I heard specific confirmation of a storyline I've been following, which is that the Bill and Melinda Gates Foundation is basically telling governments: if you want contributions/investments from us, then you'll give Microsoft cabinet-level access to inform policy, and you'll use Microsoft products. For example, donations to educational initiatives require installing and teaching Microsoft products."

Would You Like Linux With Your Jello? (Linux Journal)

ris — 2009-07-03T17:53:06+00:00

Linux Journal takes a look at a hospital with Linux thin clients for patients. "The happy healers at Glendale Adventist Medical Center, in conjunction with Linux luminaries IBM and Novell, as well as the networkers at NoMachine, have found a way to insert Linux into the lives of its patients. Rather than blank walls and bad TV to stare at, patients in the new West Tower at Glendale Adventist have access to the outside world, via Linux-based thin clients available right in the patient's room. The setup utilizes servers from IBM, the networking and compression expertise of NoMachine, and SUSE Linux Enterprise Desktop to provide patients with access to the internet, where they can do everything from learning about their condition and treatment to keeping family and friends abreast of their progress via the standard cast of internet characters: Twitter, Facebook, and the omnipresent blogs."

Milepost GCC released

corbet — 2009-07-03T13:16:05+00:00

IBM has announced the release of Milepost GCC, an extension to the GCC compiler which uses machine learning techniques to improve application performance on embedded processors. "'Our technology automatically learns how to get the best performance from the hardware -- whether mobile phones, desktops, or entire systems -- the software will run faster and use less energy,' noted Dr. Bilha Mendelson, Manager of Code Optimization Technologies at IBM Research - Haifa. 'We opened the compiler environment so it can access artificial intelligence and machine learning guidance to automatically determine exactly what specific optimizations should be used and when to apply them to ramp-up performance.'" The code can be downloaded from the Milepost site.

Stable kernels 2.6.30.1, 2.6.29.6, and 2.6.27.26

jake — 2009-07-03T03:12:51+00:00

Stable kernels 2.6.30.1, 2.6.29.6, and 2.6.27.26 have been released by the stable team. Each contains quite a number of patches (111, 35, and 32 respectively) all over the tree, some with security implications. The 2.6.29.6 release comes with an important note: "This is the last release of the 2.6.29 kernel series. All users are strongly suggested to move to the 2.6.30 release series at this time."

Pianoteq3 For Linux: A Product Review (Linux Journal)

cook — 2009-07-02T21:20:25+00:00

Dave Philips reviews the Linux version of Pianoteq (commercial software) on Linux Journal. "On the 15th of May 2009 the Modartt company announced the release of version 3.0.3 of their award-winning Pianoteq, a professional-quality digital keyboard instrument created by an audio synthesis method known as physical modeling. The program is vastly praised by its users, but in order to feel the love you've had to run a Windows machine or a Mac box. Until now, that is. The latest release introduces various new attractions, and the one that interests me the most is support for a native Linux version."

Fellowship interview with Sm�ri McCarthy (FSFE)

cook — 2009-07-02T18:10:21+00:00

The Free Software Foundation Europe presents an interview with Sm�ri McCarthy. "Stian R�dven Eide: One of the most profiled projects you have been involved with is the Fab Lab, having headed the Icelandic branch for over a year now. While best known for its use of 3D printers, the Fab Lab is actually a much broader concept that goes far beyond technical innovation. Can you tell us a bit about your work there, and what you hope to achieve? Sm�ri McCarthy: There are two sides to the Fab Lab story. On the one hand, there�s the research side, which is all about developing the universal constructors, figuring out the hard science of digital fabrication. In that realm I think our work is done when we can download chicken sandwiches off the Internet."

Virtual Linux is the prescription for hospital patients (iTWire)

cook — 2009-07-02T15:43:14+00:00

iTWire reports on a new Linux installation by a Glendale, California hospital. "Adventist Medical Center (GAMC) has installed thin clients running Linux virtual desktops in 65 patient rooms in its new West Tower. "Just as easily as the hospital provides patients with TVs in rooms, now we provide personal computing," said Roger Pruyne, senior programmer/analyst and project manager for the GAMC Patient Computing project. The system combines NoMachine's NX remote access and virtualisation software, SUSE Linux Enterprise Desktop, and an IBM System x3650 server. GAMC estimates that this approach saves 98 percent of the cost that would have been involved if conventional PCs had been selected."

[$] RealtimeKit and the audio problem

corbet — 2009-07-01T17:46:31+00:00

Skip-free audio and video playback is a fundamental expectation for many - if not most - Linux users. Given the importance of this feature and the increase in hardware performance over the years, one would think that the audio latency problem would have been solved some time ago. The recent posting of (and mixed reception for) the "RealtimeKit" mechanism shows that this issue remains open, though, and that we are still short of a consensus on how it should be solved.
