diff -u: What's New in Kernel Development

Filed under
Development
Linux

Hardware errors are tough to code for. In some cases, they're impossible to code for. A particular brand of hardware error is the Machine-Check Exception (MCE), which means a CPU has a problem. On Windows systems, it's one of the causes of the Blue Screen of Death.

Everyone wants to handle hardware errors well, because it can mean the difference between getting a little indication of what actually went wrong and getting no information at all.

Linux 3.18-rc4

Filed under
Linux

Hey, things are finally calming down. In fact, it looked *really* calm
until yesterday, at which point some people clearly realized "hey, I
should push my stuff to Linus so that it makes it into -rc4", and then
a third of all changes came in the last day, but despite that, rc4
finally looks like things are falling into place, and we'll get to
stabilize this release after all.

Here's to hoping the trend holds...

Things look fairly normal. A bit over half is drivers, and almost a
third is architecture patches (arm, powerpc, mips and s390). The rest
is a few filesystem updates (mainly XFS) and misc random stuff.

The shortlog gives a feel for the details, and nothing looks
particularly scary or odd.

Bullet Pi Interview

Interviews

So I’d seen The Matrix and also a BBC programme called Supernatural: The Unseen Powers Of Animals, where they shot dolphins jumping out of the water and they could just freeze time, and then spin round so you saw the water drops, and I thought that was a really amazing effect. And reading how it was done, it was with a whole array of cameras and it seemed quite simple. So I had the Raspberry Pi and a couple of cameras sat on my desk, and it was sort of like, ‘Well, if it seems that simple, then surely if we just got a whole load of Raspberry Pis and cameras – and they’re not that expensive – why shouldn’t we just be able to build it?’ It was one of those moments where you think it should work but you don’t actually know. So what I did was buy four cameras and I tried it, and that looked like it would work – it gave us a tantalising glimpse that we could do it.

New Kernel Live Patching Combines kGraft & Kpatch

Filed under
Linux
SUSE

Back in February SUSE unveiled a new means of live Linux kernel patching, kGraft, compared to the existing Ksplice. One month later, Red Hat unveiled their own solution that happened to be under development at the same time, Kpatch. Since both of them have been out, both have pursued mainline interests but neither one accepted upstream yet. Now a new live kernel patching solution is out that tries to take the best of both worlds.

Details Emerge on UT One Ubuntu Linux Tablet

Ubuntu

Details continue to emerge on the UT One, the tablet with an Intel processor that will run on Canonical's Ubuntu operating system. Here are the latest revelations on what will very possibly be one of the first x86-based mobile devices powered by an open source Linux distribution (yeah, Android is not really a Linux distribution).

Rumors regarding the UT One, whose developers say they will have the hardware ready to ship by the end of this calendar year, first appeared about a week ago. Since then Canonical's role has become clearer, even if the details of the relationship between the company and the UT One developers remain to be determined.

FreeBSD News: 64-bit Inodes and KDE

  • FreeBSD Lands Support For 64-bit Inodes (ino64 Project)
    While Linux and other operating systems (including DragonFlyBSD) have supported 64-bit inodes for data structures on file-systems, FreeBSD has been limited to 32-bit. But thanks to the work of many on the ino64 project, FreeBSD now has support for 64-bit inodes while retaining backwards compatibility.
  • KDE FreeBSD CI (2)
    The KDE Continuous Integration system builds KDE software from scratch, straight from the git repositories, and usually from master (or whatever is considered the development branch). It’s been building for Linux for a long time, and has recently been expanded with FreeBSD servers as well. KDE sysadmin has been kind enough to provide two more VMs (with some more compiling “oomph”) so that we can keep up better, and the CI has just been expanded with all of the Plasma products. That means we’re now building KDE Frameworks, and the Plasma desktop.

Void Linux - the Strangely Overlooked Distribution

Ahh, Void Linux. You may or may not have heard of it. If you have, more than likely it was by word of mouth, so to speak, from internet comments on a forum, YouTube video or in passing on Reddit. But this little distro rarely gets any press or recognition otherwise. Perhaps it's time that changes, as Void Linux is an interesting distro in its own right and a good alternative to something like Arch Linux. It also has a no-systemd approach. Read more
