  • The Raspberry Pi and Docker Have a Bright Future Together
    As we've noted here before, when it comes to top open source stories of the past couple of years, it's clear that one of the biggest is the proliferation of tiny, inexpensive Linux-based computers at some of the smallest form factors ever seen. The diminutive, credit card-sized Raspberry Pi, which has been priced at only $25 and $35, has grabbed most of the headlines in this space, and came out this year in a new version with a more powerful 64-bit CPU, and, for the first time, built-in wireless functionality. Now, the Pi is taking on Docker smarts. If you want to work with Docker on your Raspberry Pi, all you need is Hypriot OS, a new Debian derivative designed to run Docker on the Pi.
  • Raspberry Pi VC4 Gallium3D Makes More Progress With NIR, Camera DMA-BUF
    Broadcom's Eric Anholt has written another weekly blog post covering improvements he made over the past week to the VC4 open-source graphics driver that's known as being the driver for Raspberry Pi devices.
  • Wireless-crazed IoT gateway runs on ARM or x86 Qseven COMs
    Congatec unveiled a modular, Linux-ready IoT gateway built around its Qseven COMs, providing connectivity links including 2x GBE, 6x USB, and 3x mini-PCIe.

Open Source History: Why Did Linux Succeed?

One of the most puzzling questions about the history of free and open source is this: Why did Linux succeed so spectacularly, whereas similar attempts to build a free or open source, Unix-like operating system kernel met with considerably less success? I don't know the answer to that question. But I have rounded up some theories, which I'd like to lay out here. First, though, let me make clear what I mean when I write that Linux was a great success. I am defining it in opposition primarily to the variety of other Unix-like operating system kernels, some of them open and some not, that proliferated around the time Linux was born. GNU HURD, the free-as-in-freedom kernel whose development began in May 1991, is one of them. Others include Unices that most people today have never heard of, such as various derivatives of the Unix variant developed at the University of California at Berkeley, BSD; Xenix, Microsoft's take on Unix; academic Unix clones including Minix; and the original Unix developed under the auspices of AT&T, which was vitally important in academic and commercial computing circles during earlier decades, but virtually disappeared from the scene by the 1990s.

Red Hat goes to work on OpenStack network convergence

Red Hat has fully embraced OpenStack’s Neutron in a convergence-targeted virtualisation package. The Linux shop has released Red Hat Virtualisation 4, a package that subtly drops the reference to “Enterprise” held up until and including version 3.5 The intent seems to be for Red Hat’s virtualized Linux stack to become the platform for convergence, as opposed to merely a server density play.

Schools that #GoOpen should #GoOpenSource

The #GoOpen campaign is a terrific first step toward open education. It raises awareness of alternatives to costly and inflexible textbooks and provokes conversations about the nature of curriculum platforms and vendors. But to #GoOpen is to go only part way. Schools with the courage to embrace OER materials can amplify cost savings and student learning when they #GoOpenSource. At Penn Manor School District in Lancaster County, Pennsylvania, Linux and open source software are the foundations for more than 4000 student laptops, classroom computers, and district servers. We've saved hundreds of thousands of dollars by going open source in both the server room and the classroom. However, schools don’t have to take the plunge into desktop Linux all at once. Choosing even one open source upgrade to proprietary software can provide dramatic budget relief. Here are four open source software platforms that saved our district from resorting to bake sales: Read more
