Linux Kernel 3.13 Gets Its First Update
The latest version of this kernel branch has received its first update, but it’s a small one with just a few changes and fixes. This is normal for a new kernel, and subsequent versions should pick up the pace.

Open Source Libferris: Chasing the “Everything is a File System” Dream
The open source libferris project is a virtual file system that aims to provide a single file system interface for all data. I have been advancing libferris towards that goal over the last ten years. Over that time, libferris has gained support for mounting relational databases; physical devices like printers, webcams, and scanners; composite files like Berkeley DB and XML files; applications like Amarok, Firefox, emacs, pulseaudio, XWindow, dbus, and evolution; and more recently web services like GDrive, YouTube, Vimeo, and Flickr, as well as many other things.

Open-Source NVIDIA Driver Is Still Sour For Some GPUs
Nouveau, the reverse-engineered open-source NVIDIA Linux graphics driver that’s been in development now for the better part of a decade, is working brilliantly for some NVIDIA GeForce graphics cards while for other NVIDIA GPUs the experience is a sloppy mess. Using the Linux 3.13 kernel and Mesa 10.1-devel Gallium3D driver code installed on top of Ubuntu 13.10, here’s what the experience is like when trying a number of GeForce graphics cards with this latest open-source driver code.

SimpleDRM Driver Gets A Major Rewrite
SimpleDRM is aiming to be a rather generic and simple DRM driver for the mainline Linux kernel. SimpleDRM doesn’t do hardware acceleration but can replace multiple existing frame-buffer drivers like efifb, vesafb, simplefb, and other code. This basic DRM driver can then work with the xf86-video-modesetting X.Org driver but there isn’t yet any support for using this DRM driver on Wayland-based systems.

Linux 3.8 To Linux 3.14 Intel DRM Graphics Benchmarks
The latest benchmarks to share with you all are some tests done of all major Linux kernel releases from Linux 3.8 through Linux 3.13 and including the latest drm-next code that will land in the Linux 3.14 kernel. Here’s a look at whether Intel Haswell HD Graphics users can expect any more performance improvements out of Linux 3.14 on the graphics front.

24-Way AMD Radeon vs. NVIDIA GeForce Linux Graphics Card Comparison
After this weekend carrying out a 25-way open-source Linux graphics driver comparison featuring AMD Radeon, Intel HD Graphics, and NVIDIA GeForce hardware, the tables have now turned to look at nearly the same assortment of hardware but when using the high-performance, proprietary Linux graphics drivers. We’ve also upped the demanding OpenGL benchmarks used — including the Source Engine — as we see how the AMD and NVIDIA binary graphics drivers are doing to start 2014.

25-Way Open-Source Linux Graphics Card Comparison
As alluded to in days earlier after finding major open-source Radeon driver improvements — including the newer RadeonSI Gallium3D driver — I’ve been conducting a fresh graphics card comparison spanning many graphics processors and looking at the latest open-source driver performance on the Intel, NVIDIA, and Radeon fronts under Ubuntu Linux. In this article is a 25-way Intel Haswell HD Graphics vs. AMD Radeon vs. NVIDIA GeForce graphics comparison from Ubuntu 13.10 with the upgraded Linux 3.13 kernel and Mesa 10.1 development driver code to provide a very bleeding edge look at what the open-source drivers have to offer the Linux desktop users.

Freescale’s i.MX6 SoC Smacks The Old Intel Atom Z530
For the past few weeks I’ve had the pleasure of playing with CompuLab’s Utilite Computer. The Utilite is a miniature ARM desktop computer powered by Freescale’s i.MX6 SoC and is running Ubuntu 12.04 LTS. This is a speedy little Linux system that for some workloads can blow past Intel’s original Atom Z530 “Poulsbo” SoC system.
