With Ubuntu 14.10 "Utopic Unicorn" due for release today, here's some benchmarks showing how the standard Unity 7 desktop on Ubuntu 14.10 is comparing to the still-experimental Unity System Compositor and using XMir for running traditional Linux OpenGL games.
From a standard Intel Core i7 Haswell system with HD Graphics I ran benchmarks with the development snapshot of Ubuntu Utopic as of yesterday to see how well the stock Unity 7.3.1 environment is comparing to when it's run with unity-system-compositor installed and using Mir support with XMir for running a variety of standard OpenGL benchmarks as well as some 2D X11 benchmarks.
In October of 2004, a new Linux distro appeared on the scene with a curious name—Ubuntu. Even then there were hundreds, today if not thousands, of different Linux distros available. A new one wasn't particularly unusual, and for some time after its quiet preview announcement, Ubuntu went largely unnoticed. It was yet another Debian derivative.
With the Btrfs file-system continuing to stabilize while still adding more functionality and is generating continued interest from more Linux distributions and other open-source projects, I've found it time to run some fresh Btrfs RAID benchmarks to see how the next-generation Linux file-system is performing with its built-in RAID handling.
The Btrfs file-system offers built-in support for RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10 (1+0) modes though the support for RAID 5/6 is still considered most experimental. Besides RAID, a single Btrfs file-system can span multiple devices to yield a larger file-system. In this basic Btrfs RAID benchmarking from Ubuntu 14.10, I used two identical hard drives and tested Btrfs without RAID and then in RAID 0 and RAID 1 modes. For a separate article I'm also working on a RAID 0/1/5/6/10 comparison using for solid-state drives, which should be much more interesting, so just take this article as an introduction.
With Ubuntu 14.10 due for release tomorrow and the development branch of Mir at nearly 2,000 revisions, here's some quick Bazaar stats.
As of writing there's been 1994 revisions to the Mir Bazaar development-branch. Curious to see whether there's been any increase in outside contributions to the Mir display stack outside of Canonical, I ran bzr stats to glean some new statistics.
Given yesterday's story about Ubuntu 16.04 LTS potentially being the last 32-bit release if that proposal goes through, and given the number of people still running 32-bit Linux distributions on Intel/AMD hardware that is 64-bit capable, here's some fresh x86 vs. x86_64 benchmarks using Ubuntu 14.10.
Using Ubuntu 14.10 with the latest daily development ISOs today -- just ahead of this week's official Utopic Unicorn debut -- I did clean installs of both x86 and x86_64 flavors and carried out the same benchmarks with the same settings. Using the open-source Phoronix Test Suite automated benchmark framework made all testing easy and effortless.
This is just a quick announce: Debian packages for Juno are out. In fact, they were ready the day of the release, on the 16th of October. I uploaded it all (to Experimental) the same day, literally a few hours after the final released was git tagged. But I had no time to announce it.
This week-end, I took the time to do an Ubuntu Trusty port, which I also publish (it’s just a mater of rebuilding all, and it should work out of the box). Here are the backports repositories. For Wheezy:

Ubuntu developers had some minor problems in the week before with all sorts of bugs that were popping out. They postponed the release of a new update for the Ubuntu Touch RTM and, at one point, they even got everyone to focus on fixing the problems and nothing else. Now they have a new version out and progress really shows.
Users who already have Ubuntu Touch on their phones might have noticed that the number of features added to the system have diminished drastically, but that's the way it should be. The system is getting closer to its final stages and there is little reason to add new options now. The current form of the OS is not very far from the official release, so only fixes remain to be made.
