During the 2016 Mobile World Congress, China Mobile declared that the operational support system running their massive network would be based on open source software. China Mobile is not alone; many major networking vendors are moving to open source technologies.

Kernel 4.10 has the honor of being christened the "Anniversary Edition" by Linus Torvalds. I'm guessing this is because of the recent 25th anniversary of the release of Linux 0.01. Admittedly, it is a bit late for that (the anniversary was back in September); however, Linus had not named any of the recent releases for the occasion, opting instead for naming them after several deranged animals.

Usually, it would be another couple of months before the open-source OpenStack Foundation cloud released a new version of its cloud software. This time around the OpenStack community released the latest version, Ocata, on a one-time, shorter cycle. This release is focused on improving stability, scalability, and performance of the core compute and networking services.

About a week ago, IBM launched Quantum Experience. The cornerstone of this initiative is to make a real, working quantum computer available for anyone. This blog discusses Quantum Experience, gives the basics while trying to dwell as little as possible on Algebra or Physics and, at the end, we’ll build a simple algorithm and discuss the results.

As the new year progresses, many free and open source projects are turning their attention to various formalized mentoring programs, such as Mozilla's Winter of Security, Outreachy, and (the program with my favorite name) the X.Org Endless Vacation of Code. read more

Eugene Kaspersky, CEO of Kaspersky Lab, says its new KasperskyOS for securing industrial IoT devices does not contain "even the slightest smell of Linux", differentiating it from many other IoT products that have the open-source OS at the core.

Necessity is the mother of invention. We needed our datacenters to be more automated, so we invented tools like Puppet and Chef. We needed easier application deployment, so we invented Docker. Of course it didn't stop there. Ben Hindman, the founder and chief architect of Mesosphere, co-created Apache Mesos. In his keynote at MesosCon Asia 2016, Hindman relates how failures and elasticity led to the development of Mesos.

Vim, as you might already know, is a feature-packed and powerful editor. In this tutorial, we will focus on how you can execute external commands as well as access the command line shell from within the editor window.

To get started with IoT (the Internet of Things), your device needs, well, an Internet connection. Base Arduino microcontrollers don't have Internet connectivity by default, so you either need to add Ethernet, Wi-Fi shields, or adapters to them, or buy an Arduino that has built-in Internet connectivity. In addition to complexity, both approaches add cost and consume the already-precious Arduino flash RAM for program space, which limits what you can do. read more

This article talks about how to perform a virtual processor (vCPU) hotplug/hotunplug operation using libvirt version 2 in a PPC64LE environment.

Meritocracy is a common element of open organizations: They prosper by fostering a less-hierarchical culture where "the best ideas win." But what does meritocracy really mean for open organizations, and why does it matter? And how do open organizations make meritocracy work in practice? Some research and thinking I've done over the last six months have convinced me such questions are less simple—and perhaps more important—than may first meet the eye. read more
