SDN Series Part VI: OpenDaylight, the Most Documented Controller

Filed under
Linux
OSS

Modular application development, in which a set of loosely coupled modules can be integrated into one large application, has been one of the most successful software development practices. The term “loosely coupled” highlights the fact that the modules are both independent and can communicate with one another. OSGI (the Open Services Gateway Initiative), a dynamic module system for Java, defines one such architecture for modular application development. The SDN controller OpenDaylight (ODL), which we will be discussing in this article, is one such controller (apart from Beacon/Floodlight) that is based on the OSGi architecture. ODL is an open-source collaborative project that focuses on building a multi-vendor, multi-project ecosystem to encourage innovation and an open/transparent approach toward SDN. We need to look at these terms, “open,” “multi-vendor,” “multi-project,” “innovation,” etc., in detail to really appreciate the strengths of ODL.

Should You Use Linux for A Start Up?

Filed under
GNU
Linux

My personal experiences with Linux in the workplace actually started shortly after I adopted Linux on my home PC (well I was am still am dual booting Windows). I was at a startup who had installed Ubuntu on all the desktops, other than a few, and had no idea what they were doing. Luckily the IT guy and myself both were familiar enough with it to work through some of the early problems (mostly on the fly problem solving). Once we got past the growing pains that all start ups go though, we were in the clear. It saved the company a lot of money and, even though the new people we eventually hired did grumble about having to learn a new OS, it eventually worked out for the best.

Are Linux Graphic Apps Ready for Professionals?

Software

Yet the apparent reasonableness disappears on closer investigation. Blender, for one, was originally an in-house application for the Dutch design house Neo Geo and Not a Number Technologies (NaN) - a bit of history that immediately refutes any claim that it is not ready for professionals.

Similarly, Krita owes its increasingly popularity to the project's habit of consulting designers about each feature. Boudewijn Rempt, Krita’s maintainer, adds that ImagineFX, a major print magazine for illustrators and concept artists, recently gave Krita its Artist's Choice Award.

TraceFS: The Newest Linux File-System

Filed under
Linux

So basically TraceFS provides the same functionality now for kernel traces that is done currently via DebugFS. With TraceFS though you don't need to worry about enabling the potentially security-prone DebugFS and by having their own file-system it can implement features not supported by DebugFS (e.g. mkdir and rmdir support). Assuming it clears developer review fine, it's possible we could see TraceFS for Linux 3.20 or another near-term kernel update.

KDevelop 5.2.2 and 5.2.3 released

KDevelop 5.2.2 and 5.2.3 released We today provide a stabilization and bugfix release with version 5.2.2 and 5.2.3. 5.2.2 was tagged 6 weeks ago, but we never managed to release it because we did not have the patience to fix the Windows installers in time due to a broken CI. Windows installers are provided for 5.2.3 again. We'll only provide source tarballs for 5.2.2 and we encourage everyone to just skip this release and use 5.2.3 which contains a few more bug fixes. This is a bugfix-only release, which introduces no new features and as such is a safe and recommended update for everyone currently using KDevelop 5.2.1.
