Mobile Linux Distros Keep on Morphing (Linux.com)

Tuesday 4th of November 2014 07:58:13 PM
Linux.com looks at the distributions powering mobile devices, including Firefox OS, Tizen, Ubuntu, and WebOS. "At the Mozilla Festival held earlier this week in the U.K. , Mozilla unveiled a PiFxOS version of Firefox OS for the Raspberry Pi, also dubbed Foxberry Pi, with promises to make it competitive with Raspbian Linux. It's currently a bleeding edge demoware build, but Mozilla appears to be serious about ramping it up, with an early focus on robotics hacking and media players. PiFxOS is based on a Firefox OS port to the Pi developed by Oleg Romashin and Philip Wagner, which seems to have stalled. Mozilla plans to beef it up with support for sensors, control motors, LEDs, solenoids, and other components, as well as build a modified version for drones. A longer term project is to develop a DOM/CSS platform for robots using "a declarative model of a reactive system.""

Introducing Dynomite - Making non-distributed databases, distributed

Tuesday 4th of November 2014 01:07:10 PM
The Netflix Tech Blog has posted an introduction to Dynomite, a database distribution system. "In the age of high scalability and big data, Dynomite’s design goal is to turn those single-server datastore solutions into peer-to-peer, linearly scalable, clustered systems while still preserving the native client/server protocols of the datastores, e.g., Redis protocol." Dynomite is available under the Apache license.

Vetter: Atomic Modeset Support for KMS Drivers

Monday 3rd of November 2014 08:50:00 PM
For those who are interested in the grungy details of getting the new atomic modesetting operations working with existing graphics drivers, Daniel Vetter has the scoop: "So I've just reposted my atomic modeset helper series, and since the main goal of all that work was to ensure a smooth and simple transition for existing drivers to the promised atomic land it's time to elaborate a bit. The big problem is that the existing helper libraries and callbacks to driver backends don't really fit the new semantics, so some shuffling was required to avoid long-term pain. So if you are a driver writer and just interested in the details then read for what needs to be done to support atomic modeset updates using these new helper libraries."

Kernel prepatch 3.18-rc3

Monday 3rd of November 2014 12:52:49 PM
The third 3.18 prepatch is out there for testing. Linus complained that things aren't slowing down as he would like, but doesn't seem too worried: "That said, I don't think there is anything particularly horrible in here. Lots and lots of small stuff, with drivers accounting for the bulk of it (both in commits and in lines), but networking and core kernel showing up too. Nothing particularly stands out." With this prepatch, the codename for the release has changed to "Diseased Newt."

Fedora Council elections scheduled

Friday 31st of October 2014 10:26:56 PM

Fedora Project Leader Matthew Miller has announced the election schedule meant to fill the two new "at large" slots on Fedora's upcoming Fedora Council governance body. "These positions are of strategic importance, with a full voice in the Council's consensus process. The primary function of the Council is to identify community goals and to organize and enable the project to achieve them." Nominations will be open from November 4 through 10; voting be open from November 18 through 25. The week in between will be for campaigning. Miller also encourages potential candidates to consider the time commitment the new roles require. "We recognize that this level of commitment is difficult for many community members with full-time jobs not directly related to Fedora, and the intent is not to exclude those contributors. At the same time, these positions will require a meaningful commitment of time and responsiveness. If your other obligations make this impossible, please consider suggesting candidacy to other community members who you feel would be able to bring your voice to the table."

KVM Matures, and the Use Cases Multiply (Linux.com)

Thursday 30th of October 2014 07:41:34 PM
Over at Linux.com, Adam Jollans has a report from the recently completed KVM Forum that was held in Düsseldorf, Germany October 14-16. He looks at a talk that he gave on KVM's relationship to OpenStack and the open cloud, a new white paper on KVM [PDF], and a panel on network function virtualization (NFV): "In the past, communications networks have been built with specific routers, switches and hubs with the configuration of all the components being manual and complex. The idea now is to take that network function, put it into software running on standard hardware. The discussion touched on the demands – in terms of latency, throughput, and packet jitter – that network function virtualization places on KVM when it is being run on general purpose hardware and used to support high data volume. There was a lively discussion about how to get fast communication between the virtual machines as well as issues such as performance and sharing memory, as attendees drilled down into how KVM could be applied in new ways."

Tiny quad-core ARM mini-PC runs Ubuntu with Cinnamon

A startup is pitching a $129-$199 “Imp” mini-PC on Indiegogo based on a quad-core Odroid-U3 SBC, with HDMI streaming and an Ubuntu/Cinnamon Linux desktop. A day after reporting on one Israeli-based, non-Android ARM mini-PC — SolidRun’s $100 CuBoxTV with OpenElec Linux — here comes another. Aside from the usual hyperbole found on crowdfunding pages — are we really “democratizing the digital home experience” or just buying an embedded ARM computer? — the Ubuntu-based Imp mini-PC looks like a pretty good deal.

Ready to give Linux a try? These are the 5 distros you need to consider

There are so many Linux distributions that choosing one can be overwhelming for a new user. One might be too intimidating for a user to even try, while another might be too simplified, blocking that user from knowing how Linux systems actually function. I have been using Linux as my primary OS since 2005 and have tried all major (and quite a lot of minor) distributions. I have learned that not every distribution is for everyone. Since I also assist people in migrating to Linux, I have chosen the 5 distros that I recommend to new users based on their level of comfort and desire to learn (or not learn) more about Linux.
