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.

Android Leftovers

  • 1B Android phones shipped in 2014, but they don’t all help Google
    When Android first arrived in 2007, it was (and still is) a key part of the OHA, or Open-Handset Alliance. OHA partners — which include Samsung, LG, Dell, HTC, Huawei and ZTE, to name a few — all loosely work together to help improve Android, while competing against one another by using Android on their respective hardware products. Android is the commonality between all of the OHA partners. And then there’s Google.
  • Android beats iOS for app downloads, but revenues are still a different story
    There are plenty of caveats to this line of reasoning, though. First, Google Play is not the only Android app store – Amazon and Samsung run their own stores, while in countries like China there are dozens of stores offering Android apps.
  • HTC One M8 Android 5.0 Lollipop Update: What U.S. Owners Can Expect
    When Google announced Android 5.0 Lollipop back in October many smartphone owners like those with the HTC One or HTC One M8 instantly started waiting for details regarding the Android 5.0 Lollipop update. It has arrived for a few devices already, including the HTC One and HTC One M8 Google Play Edition handsets, but below we’ll go over what regular HTC One owners need to know about the Android 5.0 update.
  • Samsung Galaxy S4 Updated To The Android Lollipop 5.0 OS
    The Android Lollipop 5.0 update is finally available for the Samsung S4. The operating system is also available for the Samsung Galaxy S5, Note 4, Note 3, and Note Edge. Samsung Galaxy and Note users will be happy to hear that the long waited update is coming in the near future. But should Galaxy S4 users take advantage of the Android Lollipop update?
  • Don’t wait for Android 5.0, this app makes your phone look like Lollipop for free
    Android 5.0 Lollipop is a huge upgrade for Google’s mobile operating system. The only problem with it, of course, is that it’s only available for a handful of devices. Most Android smartphone users still have plenty more waiting to do before Lollipop is finally available for their handset, but now there’s a terrific app that will make your older version of Android look just like Lollipop — and it’s free!
  • Is this Apple’s secret weapon that could force Android users to buy an iPhone?
    There are many reasons why Android users switch to iPhone, and vice-versa, but Apple may have a secret (or not-so-secret) weapon that could pressure some Android fans to considering a move to the other side. No, it’s not Apple Pay, an exclusive iPhone 6 feature that’s heavily marketed by various banks in the U.S., further helping Apple market its 2014 iPhones. It’s actually a stock iOS app that has been hiding in plain sight for years.
  • Android 5.0.2 Lollipop Problems Frustrating Nexus Users
    Google rolled out its Android 5.0.2 Lollipop update to fix Nexus Lollipop problems. And while it did fix some of the bigger issues, Android 5.0.2 Lollipop problems continue to frustrate Nexus users.
