Debian 8.0 Jessie Is Settling For Linux 3.16

Filed under

Debian

Recently the Debian developers and other stakeholders have been trying to decide between basing Debian 8.0 Jessie's Linux kernel on the 3.14 release, which is Greg KH's latest long-term stable kernel, or to use Linux 3.16. The benefit of Linux 3.16 is that it's intended to be used by Ubuntu 14.10 and thus will receive support from the Canonical/Ubuntu kernel team for the better part of two years after its October debut. Linux 3.16, of course, has many improvements, new drivers, and other hardware support improvements over Linux 3.14.

2014 Calligra Sprint in Deventer

Filed under
KDE

From the fourth to the sixth of July, the Calligra team got together in sunny Deventer (Netherlands) for the yearly developer sprint at the same location as the last Krita sprint. Apart from seeing the sights and having our group photo in front of one of the main attractions of this quaint old Dutch town in the province of Overijssel, namely the cheese shop (and much cheese was taken home by the Calligra hackers, as well as stroopwafels from the Saturday market) we spent our time planning the future of Calligra and doing some healthy hacking and bug fixing!

Linux 3.16-rc7

Filed under
Linux

I'm happy to say that things have calmed down a bit, and things look
to be on track.

Which didn't actually seem to be the case at all earlier this week -
we had what appeared to be really nasty core bugs, and together with
rc6 being bigger than previous rc's, I was really not feeling all that
good about this release there for a while.

But the worst "nasty bugs" ended up clearing up and not being kernel
bugs at all. One turned out to be a compiler issue (which is always
very scary and hard to debug and very annoying), and it even had a
fairly simple workaround so that we didn't end up having to blacklist
compilers. Another turned out to be lockdep just being too aggressive,
and a false positive.

We obviously *do* have various real fixes in here, but none of them
look all that special or worrisome. And rc7 is finally noticeable
smaller than previous rc's, so we clearly are calming down. So unlike
my early worries, this might well be the last rc, we'll see how next
week looks/feels.

In numbers, rc7 is about one third arch (xtensa, powerpc, x86, s390,
blackfin), one third drivers (gpu, media, networking), and one third
"random" (networking, mm). But it's all fairly small. Shortlog
appended.

Open-Source AMD Users Report Hawaii GPU Acceleration Is Working

Filed under
Graphics/Benchmarks

AMD Hawaii support works with GLAMOR (both with the external library and the internal support found in X.Org Server 1.16), is running a variety of Steam games, etc. As a word of caution, MSAA might be one of the currently broken Hawaii features unless additionally applying a libdrm patch. Among the titles people are reportedly trying with the Hawaii GPU on RadeonSI Gallium3D include Civilization 5, Half-Life 2, Metro: Last Light, Portal 2, and XCOM: Enemy Unknown. The performance on the open driver is said to be satisfactory in most situations but with XCOM for instance the frame-rate on a R9 290 class GPU is under ten frames per second and there's also issues with GPU stalls. A big problem reported by a user comes down to very poor performance in playback of video streams, such as from Twitch.

A KDecoration2 update

Filed under
KDE

Before heading into the weekend I thought about writing a small update about the KDecoration2 status. Since my last blog post I started integrating KDecoration2 into KWin. This was partially easier and partially more difficult than anticipated. Especially ripping out the old decoration code is rather complex. There are quite some design differences which make the transition complex and especially values inside KWin core are using enums defined in the decoration API – e.g. the maximized state is kept as a KDecorationDefines::MaximizedMode. This will need further work to move the enums and so at the moment the old decoration library is still compiled although the library is no longer in use.

Open Source and the Challenge of Making Money

Filed under
OSS

Remember how the open source software movement was supposed to be like Woodstock, with everybody sharing and everything free? An entire economy where you gave a little to get a lot, in a place of love and software?

At the risk of bringing down your summer, it’s time to admit that this idea didn’t work out.

Take Big Switch Networks, a company that hoped to be for computer networking what Linux operating system software is for computer servers. A few years ago, Big Switch proposed building networking controller software that was crowd-created and free, which could demolish proprietary networking boxes. It would also offer a commercial version, with a few tweaks, that could be the basis of a great, profitable empire.

OnePlus coming to India!

Filed under
Android

An administrator responded on the OnePlus blog by giving a clear indication the One will eventually be available to buy in India. At launch (even though there was no official launch) the OnePlus One was only available in North America and Europe. However it now seems that India is one of the country’s most eager to purchase the device. According to the OnePlus blog India ranks eight in the world via traffic trying to obtain the device through the OnePlus site. If this is correct than this ranks India higher than a number of the countries the device was actually launched in.

Ripe Linux Nits To Pick

Filed under

I remember when I dove into Linux at full tilt boogie. It was 2004. Nickelback could still be found in the top 10 charts, The Boston Red Sox broke the Curse of the Bambino and wireless support in Linux absolutely sucked. What a long way we’ve come. So these days, when people gripe about this or that not working in Linux, most of those complaints seem almost trivial.
