Btrfs is a new file system for Linux, one that is still very much in development. Although I wouldn't exactly describe it as "experimental" any more, it is, as stated in the Wiki at kernel.org, "a fast-moving target".
It has also been said publicly that the basic format and structure of the filesystem should now be stable; it would only be changed in the future if some overriding reason or need is found.
The point of all this should be clear — it is still very early days, and it is not recommended to use btrfs in critical systems of any kind.
I leave it to the reader to decide how critical their systems are; for my own purposes, I will be using btrfs on several systems that I use as testbeds, some of which I carry with me and use for normal work on a daily basis, so it will get a "real" test, but I will not be using it on the primary systems that my partner and I use for home/work/business activities.
Martin Gräßlin, KDE's Kwin maintainer, has shared some new OpenGL implications due to changes made in the KWin 5 window manager due to relying on Qt5 with Qt Quick 2.
Defining hardware as “older” is tricky. Newer resource hungry software levering on the pace of hardware developments is rendering even relatively newer hardware obsolete. Examples of these relatively recent “older” hardware would be single-core or dual-core AMD Athlons and Intel Pentiums.
Russian robot developer R.bot will soon launch a pair of low-cost telepresence robots in North America. The Synergy Mime and larger Synergy Swan use an attached BYOD Android smartphone or tablet for display, camera, microphone, and wireless communications and control functions, and are being offered for a limited time to Android developers for $250 and $500, respectively.
When the Raspberry Pi was developed, founder Eben Upton envisioned that the low-cost computer would do its finest work in the classroom, teaching kids about computing. But as more units sold, Raspberry Pi developed a strong, distinctive niche among adult makers, a fruitful group that nonetheless doesn’t really have much in common with a younger age bracket that can be hard to reach.
Back during Google IO 2012, Android 4.1 Jelly Bean was officially unveiled unto the world. Major firmware versions always bring their share of new features, it was a little something Google called Project Butter that got us the most excited. Addressing Android less than consistent frame rates, Project Butter looked to finally make the Android UI as silky and smooth as iOS butter.
InfoWorld's Simon Phipps has written before about how Nokia and BlackBerry could have been major competition for Apple had they embraced more open ecosystems. It's unlikely Jolla and Sailfish will make much of a dent in a marketplace already ruled by Android, despite Sailfish's Android compatibility. But given how much ex-Nokia talent is bound up in this project, it'll be worth watching just to see how their approach unfolds and whether it'll become its own animal or just another way to run Android.
Docker is a tool for bundling everything you need to run a particular application into a single “container.” These containers can be moved from computer to computer — be they physical machines or virtual computer servers — in much the same way a standardized shipping container can be loaded onto any ship or train or loading dock.
The first iBuyPower Steam Machine is expected to be powered by an AMD processor and is said to have a Radeon R9 270 graphics card. It's nice to see it's not a problematic R9 290 GPU and the R9 270X works well under Linux when using the Catalyst driver. The iBuyPower device will surely be using the binary blob for better OpenGL support and performance with the RadeonSI Gallium3D driver being only half-baked for GCN hardware.
