Many Linux and open source leaders gave presentations at LinuxConf.Au 2015 a few weeks ago, including Linux Creator Linus Torvalds. All of the conference videos are available on YouTube, and there were many excellent presentations -- so many it would be impossible to watch them all. The range of topics covered everything from open source governance and community management, to inspiring uses of Linux and open source technologies, to technical talks and tutorials. Here are ten interesting technical talks focused on Linux and the kernel. (Disclaimer: I have not watched every single minute of all of these videos. I'll leave it to you to decide how captivating they are.)
ArduPilot is the open source software which controls our own Vulture 2 spaceplane on the 3DR Pixhawk autopilot. As Tridge demonstrated, it can now be deployed on a range of hardware which, with the addition of a suitable interface, allows aficionados to create a fully-functioning autopilot.
Last year, for example, a group of Russians successfully raised funds for the Navio, an autopilot shield for the Raspberry Pi.
As part of his talk, Tridge connected live to a model aircraft in Canberra, in this case equipped with an embedded Linux box - the BeagleBone Black - coupled to a PixHawk Fire Cape (PXF).
Samsung Electronics Co. have revealed that they plan to sell 30 million Tizen TVs in 2015, according to an Industry source. Samsung aim to ship an estimated 60 million TVs in 2015 with Tizen TVs expected to be over 50% of that figure. These will be using the new quantum-dot display technology which has the capability of showing 1 billion colours, which is 64 times more than what current TV models can perform.
The Linux Foundation original video, "How Linux Was Built," reached a huge milestone in 2014, surpassing 1 million views on YouTube. The video, one of the ten most popular on the Linux Foundation YouTube channel last year, illustrates how thousands of software developers from all over the world contribute collectively to the Linux kernel codebase. It's the kind of video you can show to your parents and friends that will help them understand what makes Linux such an amazing software project. And its popularity also illustrates just how mainstream Linux and open source software have become.
Samsung announced at last week's International CES a new line of smart TVs powered by the open source Tizen operating system. Beginning with this year's models, all of Samsung's smart TVs will run on Tizen.
Samsung has taken the lead in developing Tizen, which is a derivative of Linux, and this is its first deployment as a smart TV platform. Tizen supports the Web standard for TV app development.
Android TV, in case you've had your ears plugged lately, is Google's latest effort at getting its software into your home entertainment setup. At CES this week, Google announced that Sony, Sharp, and Philips all had Android TV-powered televisions in the works for this spring. A set-top Android TV gaming console is supposed to launch next month, meanwhile, and at least one standalone streaming media player is scheduled to arrive later this year.
Each year, as I search through CES product launches to see which run Linux, I get the feeling I'm looking at an iceberg. There are probably a lot more tuxified devices out there than I'll ever have time to track down. At this year's Internet of Things-laden show, the list of potentially Linux based gizmos has grown even larger.
Certainly, there are plenty of vendors that openly proclaim their products' Linux roots (see farther below), but more often vendors keep mum, implying they created the secret sauce all by themselves. Even when you ask, they often don't tell. It's easier to identify technology using the Linux-based Android, but now that Android's cool factor has waned due to its overwhelming success, some vendors even obscure their Android foundations.
First was 2010’s Google TV software, which lost millions for hardware makers such as Logitech; second in 2013 was Chromecast, a memory stick-sized device to plug into your TV; it has sold “millions”, though Google won’t specify how many.
Now in 2015 there’s Android TV. Will it take off? The trouble with “connected TVs” is that though almost every TV now sold can go online, few owners take advantage of it.
As of today Kodi from Debian uses the FFmpeg packages instead of the Libav ones which have been used by XBMC from Debian. The reason for the switch was upstream’s decision of dropping the Libav compatibility code and FFmpeg becoming available again packaged in Debian (thanks to Andreas Cadhalpun). It is worth noting that while upstream Kodi 14.0 downloads and builds FFmpeg 2.4.4 by default, Debian ships FFmpeg 2.5.1 already and FFmpeg under Kodi will be updated independently from Kodi thanks to the packaging mechanism.
