Btrfs hands on: My first experiments with a new Linux file system

Filed under
Linux

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.

Linux 4.0-rc2

So rc2 missed the usual Sunday afternoon timing, because I spent most of the weekend debugging an issue that happened on an old Mac Mini I have around, and I hate making even early -rc releases with problems on machines that I have direct access to. Even if it only affected old machines that actual developers are unlikely to have or at least use. Today I got the patch from Daniel Vetter to fix it, so instead of doing a Sunday evening rc2, it's a Tuesday morning one. Go get it. It works better for the delay. Other than that little one-liner i915 fix? Not much, actually. It's been a very quiet week, for being this early in the release process. Sure, 3.19-rc2 was even smaller, so it continues a trend, but that was the xmas week. I hope this low volume is just because the 4.0 merge window itself was somewhat calmer than most recent releases. But I suspect the real reason is that the driver and networking trees from GregKH and davem are pending, and didn't make rc2. We'll see. Anyway, the shortlog is appended, and testing is appreciated, Linus Read more

New Ubuntu Phone Separates the App from the Data

As CIO Journal has noted, Mr. Shuttleworth envisions the rise of an Ubuntu-powered phone that runs desktop grade applications and plugs into peripherals such as large displays and keyboards. In other words, he is working to achieve true mobile-desktop-laptop convergence — the only computer you need, in your pocket, all the time. He tried to raise $32 million to fund development of such a phone, known as the Edge, in a widely publicized crowdfunding campaign on Indiegogo. The campaign ended in 2013, short of its goal.
