Unikernels promise some interesting benefits. The Ubuntu 14.04 amd64-disk1.img cloud image is 243 MB unconfigured, while the unikernel ended up at just 5.2 MB (running the queue service). Ubuntu runs a large amount of C code in security-critical places, while the unikernel is almost entirely type-safe OCaml. And besides, trying new things is fun.
First off, Happy SysAdmin Day. We think we have a pretty good SysAdmin surprise in store for you today as we are announcing the CoreOS stable release channel. Starting today, you can begin running CoreOS in production. This version is the most tested, secure and reliable version available for users wanting to run CoreOS. This is a huge milestone for us. Since our first alpha release in August 2013:
191 releases have been tagged
Tested on hundreds of thousands of servers on the alpha and beta channels
Supported on 10+ platforms, ranging from bare metal to being primary images on Rackspace and Google.
Earlier this month, I spent a day working in the throwback world of DOS. More specifically, it was FreeDOS version 1.1, the open source version of the long-defunct Microsoft MS-DOS operating system. It's a platform that in the minds of many should've died a long time ago. But after 20 years, a few dozen core developers and a broader, much larger contributor community continue furthering the FreeDOS project by gradually adding utilities, accessories, compilers, and open-source applications.
All this labor of love begs one question: why? What is it about a single-tasking command-line driven operating system—one that is barely up to the most basic of network-driven tasks—that has kept people’s talents engaged for two decades? Haven't most developers abandoned it for Windows (or, tragically, for IBM OS/2)? Who still uses DOS, and for what?
Just announced in the last few hours, CentOS 7 for x86-64 has arrived. This is the first release under the new arrangements since Red Hat reversed into CentOS, leaving the distro independent but hiring a number of key players. Apart from this being a rapid arrival for a major new release, the announcement notes that they aim to get future updates heading out within 24-48 hours of release. There’s a new versioning system too, so this is Cento 7.0-1406,14/06 being June 2014, when Red Hat released RHEL 7.0 and the code base that this release of CentOS was built on. There’s torrents available for the DVD ISO, “Everything”, GNOME Live (the announcement has a malformed link for that.
We’ve seen Tizen-based smartwatches and phones, among other form-factors. Now Tizen is heading for the car. The Linux Foundation’s Automotive Grade Linux (AGL) project released its first open source IVI stack based on the Tizen IVI version of the Linux-based operating system.
Alpine Linux is not a distribution designed for beginners. In fact, it’s exactly the opposite. Users will need to be well accustomed to use a terminal. For example, you have to work a little just to install a desktop environment.
“The Alpine Linux project is pleased to announce the immediate availability of version 3.0.1 of its Alpine Linux operating system. This is a bugfix release of the v3.0 musl based branch. This release is based on the 3.14.8 kernel which has some critical security fixes,” said the developers in the shortlog.
