Snowmix is a video mixer tool for mixing live and recorded video and audio feeds. It supports clipping, scaling and transparent overlay of video, png graphics and text. It supports animation of video, images and texts through native commands changing scale, placement, transparency and rotation. Animation and actions can also be controlled through native scripting and an embedded Tcl interpreter. Snowmix is designed for control over low bandwidth links and can work as a standalone CLI based program. Control over both CLI and a TCP connections. Live and recorded video feeds can be fed to the mixer via GStreamer pipelines. Output can be accessed through GStreamer pipelines.

rTorrent is a quick and efficient BitTorrent client that uses, and is in development alongside, the libTorrent (not to be confused with libtorrent-rasterbar) library. It is written in C++ and uses the ncurses programming library, which means it uses a text user interface. When combined with a terminal multiplexer (e.g. GNU Screen or Tmux) and Secure Shell, it becomes a convenient remote BitTorrent client.

Weekly Spotlight


The cost for me to share music is low, and the benefits are high. There are a lot of schools with no money, and plenty of film makers who want to have music – but can’t afford to clear copyrights from the existing systems that are set up. I believe that copyright is badly broken , so I chose a license that allows me to to give away the rights I wish to surrender.

PC gaming is expanding, Valve’s GDC 2015 announcements recap

Valve Controller Final

Valve attended GDC in full force this year and talked about a lot of stuff. Here’s everything they talked about it in one post.

More than 50 titles are highlighted, including three of PCWorld’s favorite games of 2014The Talos Principle, Transistor, _and our Game of the Year, _Wasteland 2—and a slew of other spectacular titles like Metro Redux, The Witcher 2: Assassin of Kings, Borderlands: The Pre-Sequel, Civilization: Beyond Earth, XCOM: Enemy Unknown, _and _Goat Simulator, among many others.

This drop to just over 1.0% is the lowest numbers we’ve seen for Linux’s representation on Steam in quite a number of months. However, it’s not a huge surprise.

With the Vulkan API still in flux and not finalized until later this year, Valve has been developing their own Intel GPU reference driver for Vulkan to help early adopters boot-strap their code. Valve said during their presentation today at GDC2015 that this Intel Linux driver will be open-sourced, but they haven’t provided a time-frame for doing so.

VMware alleged to have violated Linux’s open source license for years

Christoph Hellwig

Linux kernel developer Christoph Hellwig filed the suit in the district court of Hamburg, Germany with funding from the nonprofit Software Freedom Conservancy, which works to “promote, improve, develop, and defend” free and open source software. The case centers on “a combined work that VMware allegedly created by combining their own code (‘vmkernel’) with portions of Linux’s code, which was licensed only under GPLv2,” _the group said in an FAQ describing the lawsuit._

Software Freedom Conservancy

Software Freedom Conservancy announces today Christoph Hellwig’s lawsuit against VMware in the district court of Hamburg in Hamburg, Germany. This is the regretful but necessary next step in both Hellwig and Conservancy’s ongoing effort to convince VMware to comply properly with the terms of the GPLv2, the license of Linux and many other Open Source and Free Software included in VMware’s ESXi products.

​No reboot patching comes to Linux 4.0

Living patching in Linux 4.0

At the Linux Plumbers Conference in October 2014, the two groups got together and started work on a way to _patch Linux without rebooting that combines the best of both programs. Essentially, what they ended up doing was putting both kpatch and kGraft in the 4.0 Linux kernel._
