Years ago, in a graduate computer science course, I was tasked with implementing an algorithm for "variational image segmentation by motion detection." The algorithm was, as they say, a doozy. Tersely described over the course of half a dozen papers, it had dozens of subroutines, which when implemented grew to span thousands of lines of MATLAB code. But there was one subroutine, mysteriously called the "numerical upgrading" routine, whose description was mysteriously absent from the scientific record. Without this small but vital routine, the whole marvelous image segmenting machine just sputtered and ground to a halt. Crash! Panic! Woe.

“Pushing that button was one of the more impactful clicks of my career,” says Microsoft’s C# lead architect Anders Hejlsberg. The click in question was made on stage at Microsoft’s Build conference in April, and its effect was to publish the .NET Compiler platform, codenamed Roslyn, as open source under the Apache 2.0 licence.

"One of the great things about Linux, especially for web developers or server administrators, is that all of the basic tools you need to get set with your remote server and files tend to be included and well integrated into the system from the get go. You don't necessarily need to install an FTP client, a code editor or a special terminal emulator."

Windows XP was around for a long time and as such the hardware used to run Windows XP varied from Pentium II machines to dual core processors with many gigabytes of RAM. Therefore one Linux distribution doesn't necessarily fit for all Windows XP users. This article lists 5 reasons why and when Lubuntu would be a good choice.

Open science is one way today to deliver science to societies around the world. And, it can include open education, open research, open source, and open culture. read more

For more than three years now, Microsoft has held to the line that it has loads of patents that are infringed by Google's Android operating system. "Licensing is the solution," wrote the company's head IP honcho in 2011, explaining Microsoft's decision to sue Barnes & Noble's Android-powered Nook reader.

Microsoft has revealed a few of those patents since as it has unleashed litigation against Android device makers. But for the most part, they've remained secret. That's led to a kind of parlor game where industry observers have speculated about what patents Microsoft might be holding over Android.

Hello everyone, we have a lot of cool stuff in the Roundup this week including and interview with Linus Torvalds, a little known and very little (as in 30 kilobytes) OS called Contiki, Cent OS7 is on the way, ARM developer Sean Cross's Linux rig as well as HP's in house Linux OS and has Heartbleed got us overreacting to all OS bugs in general? Enjoy!

In this tutorial we will show you how to set up multiple SSL Certificates on a CentOS VPS with Apache using one IP address only.

Codethink demonstrated its Baserock Linux stack running the new Linux 3.15 kernel and an open source graphics driver stack on Nvidia’s Jetson TK1 SBC. Codethink ported Baserock with the new Linux kernel to the Jetson in 24 hours to promote its Linux stack’s workflow tools while also showing off the capabilities of Nvidia’s open source Linux development board. “This shows what’s possible with the right people working on a fully open source software stack with Baserock,” stated Paul Sherwood, CEO of Manchester, UK-based Codethink. “Linux 3.15 was released late Sunday in California. We got our board on Monday. James started the work on Tuesday. By Wednesday we had a fully working system, with wayland and weston running EGL clients using totally open technologies.”

LXLE acronym change, originally 'Lubuntu eXtra Life Extension' which made sense before Lubuntu had an official LTS release, since 14.04 however, LXLE will now adopt the nomenclature 'LXDE eXtra Luxury Edition' and we think this release doubles down on that; to better support 32-bit hardware we updated 12.04.4 to be virtually identical to LXLE 14.04 64-bit release including features, updated software and system components; PCManFM additions such as open directories and text as root, create shortcuts, rename base icon names, copy to folder, right click desktop trash to empty; Launch (Fehlstart), Run (Gexec), and Terminal (RoxTerm) all have hotkeys enabled to open them using the keyboard for faster access, and more.

Marvell has posted detailed datasheets on its previously opaque Armada 370 SoC, used in Linux-based NAS systems from Buffalo, Netgear, and Synology. Until now, datasheets and other details about the ARM-based Armada 370 system-on-chips have been available only under NDA to Marvell customers and partners. Last week, however, the chipmaker released two detailed datasheets on […]
