LibbyMC writes: Mesosphere Founder Benjamin Hindman presents a model for how Mesos and a data center operating system, such as the one it announced four months ago, could help facilitate interoperability, and portability, in the open cloud.
“We can get to the world where we have a POSIX-like API for distributed systems, so that anybody can build a distributed system and effectively compile it against this API,” said Benjamin Hindman, Founder of Mesosphere and former lead of the Mesos project at Twitter. “Mesos can provide this POSIX API.”

LibbyMC writes: Executive Director Jim Zemlin writes, "We do not agree with everything Microsoft does and certainly many open source projects compete directly with Microsoft products. However, the new Microsoft we are seeing today is certainly a different organization when it comes to open source.
"The company's participation in these efforts underscores the fact that nothing has changed more in the last couple of decades than how software is fundamentally built. "
LibbyMC writes: For a few years now Linux kernel developers have followed a fairly strict authentication policy for those who commit directly to the git repositories housing the Linux kernel. Each is issued their own ssh private key, which then becomes the sole way for them to push code changes to the git repositories hosted at kernel.org. While using ssh keys is much more secure than just passwords, there are still a number of ways for ssh private keys to fall into malicious hands. So they've further tightened access requirements with two-factor authentication using yubikeys.
LibbyMC writes: Linux creator Linus Torvalds has given a personal video tour of his workspace, filmed by the Linux Foundation. It also includes behind the scenes laughs and footage, as well as a closer look at what he keeps on his desk and what he does between kernel releases.
LibbyMC writes: ownCloud Founder Frank Karlitschek explains why he built the file storage service as open source software.
"I believe that file storage is not just another web service or IT infrastructure. This is where people and companies store and manage their most important data. Because of that it is essential to have it as secure and safe as possible. With proprietary software you can never be sure if there are any back doors or other security problems with the software. Open source is the only option for file storage that is really safe and secure."
LibbyMC writes: An anonymous hacker (or hackers) going by the name Little Penguin has created the Eudyptula Challenge, modeled after the Matasano Crypto Challenge, as a way to get more developers involved with the Linux kernel. Challenge participants sign up by sending an email to Little, who sends them a series of programming tasks commonly employed by Linux kernel developers. All you need to start is some C programming experience. Little penguin answers questions here: http://www.linux.com/news/feat...
LibbyMC writes: Beyond giving every student a new Acer TravelMate laptop pre-loaded with Ubuntu 13.10, the Penn Manor High School 1:1 laptop program set out to teach open source principles and introduce a culture shift. IT staff led evening “tech camps” for parents in the district and training sessions for teachers to help them become more familiar with the installed applications as well as the concept of open source software. And a group of seniors was brought in as help desk apprentices to do web design, hardware testing, and deployment. http://www.linux.com/news/feat...
LibbyMC writes: Along with Open Compute, OpenStack and CloudStack, the OpenDaylight software defined networking project's first "Hydrogen" release brings a significant challenge to proprietary networking platforms.
"The idea of allowing a vendor to populate your data center with proprietary servers and storage is falling to open compute specified designs and storage, which either adheres to one of several open models including solid state storage as part of the compute operations or replaces on-site storage with cloud-based storage. CIOs recognize that the skills needed in this open era may not exist in house and may not exist within the traditional consulting organizations used to upgrade hardware and software infrastructure."
LibbyMC writes: Karanbir Singh talks openly about what it will mean for CentOS as a project, and for him personally, to join a big open source company and work professionally on the project for the first time. Will CentOS become a proving ground for new technologies in RHEL as some commenters have speculated?
"I think it should. But it would be wrong to say it will be a proving ground for things into RHEL. It's more appropriate to say it's a proving ground for anything. Because the platform is resilient you can build on CentOS without things caving in. There's nothing in what we're doing that limits ourselves to what Red Hat is doing."
LibbyMC writes: Google's approach to bringing older C software to the browser is demonstrated in bringing the 80's era Amiga OS to Chrome. "The Native Client technology runs software written to run on a particular processor at close to the speeds that native software runs. The approach gives software more direct access to a computer's hardware , but it also adds security restrictions to prevent people from downloading malware from the Web that would take advantage of that power."
LibbyMC writes: The exercise is not to create a production Cassandra network but to make it possible for students to experience the database running on multiple ethernet connected computers without building datacenters and server racks. By scaling down the platform, without rewriting it, something that the combination of Linux and Java on the Raspberry Pi make easy, then the problems of scaling up become much easier to examine in the same way a scale model of a bridge lets architects see physical stress in action.
LibbyMC writes: Richard Purdie has built a new core compiler so that anyone who builds an embedded project with the Yocto Project will now have access to the ability to compile Linux binaries on all three platforms.
Purdie noted that others before him have built Windows binaries with OpenEmbedded but the capability had been lost for many years. This new development brings it to the Yocto Project and its updated architecture. The ability to build for Mac OSX is completely new.
LibbyMC writes: Linus Torvalds and the Linux kernel developers talked on stage today at LinuxCon and CloudOpen on a range of topics, from personal hobbies to advice for getting patches upstream. But one consistent theme emerged in the discussion: Growing the size and diversity of the Linux kernel developer community — on the kernel side as well as in user space — will help push continued innovation even as technology changes.
LibbyMC writes: The latest Linux kernel release has a lot of new features. This is an overview of four changes that will boost performance and lower power use: Zswap, AMD Radeon DPM support, low latency network polling and Xen and KVM support on ARM64.
