First time accepted submitter Olivier Bonaventure writes "The TCP protocol is closely coupled with the underlying IP protocol. Once a TCP connection has been established through one IP address, the other packets of the connection must be sent from this address. This makes mobility and load balancing difficult. Multipath TCP is a new extension that solves these old problems by decoupling TCP from the underlying IP. A Multipath TCP connection can send packets over several interfaces/addresses simultaneously while remaining backward compatible with existing TCP applications. Multipath TCP has several use cases, including smartphones that can use both WiFi and 3G, or servers that can pool multiple high-speed interfaces. Christoph Paasch, Gregory Detal and their colleagues who develop the implementation of Multipath TCP in the Linux kernel have achieved 50 Gbps for a single TCP connection [note: link has source code and technical details] by pooling together six 10 Gbps interfaces."

There have been video editing apps available for Linux for years, from ones meant to be friendly enough to compete on the UI front with iMovie (like the moribund Kino, last released in 2009, and the actively developed PiTiVi and Kdenlive) to editors that can apparently do nearly anything, provided the user is a thick-skinned genius — I'm thinking of Broadcast 2000/Cinelerra. Then there's VJ-tool-cum-non-linear editor LiVES, which balances a dense interface with real-time effects for using video as a performance tool, and can run on various flavors of UNIX, including Mac OS X. Dallas-based developer Jonathan Thomas has been working for the last few years on a Free (GPL3 or later), open-source editor called OpenShot, which aims for a happy medium of both usability and power. OpenShot is Linux-only, though, and Thomas is now trying to kickstart (as in, using a Kickstarter project) a cross-platform release for OS X and Windows, too. I've been tempted by dozens of KickStarter projects before, but this is the first one that I've actually pledged to support, and for what may sound like a backwards reason: I like the interface, and am impressed by the feature set, but OpenShot crashes on me a lot. (To be fair, this is mostly to blame on my hardware, none of which is really high-end enough by video-editing standards, or even middle-of-the-road. One day!) So while I like the idea of having a cross-platform, open-source video editor, I have no plans to migrate to Windows; I'm mostly interested in the promised features and stability improvements.
