    Announcing GitTorrent: A Decentralized GitHub

    At his blog, Chris Ball announces "GitTorrent," his new project designed to let developers host Git repositories on BitTorrent. The system takes advantage of Git's ability to run over arbitrary network protocols. "We ask for the commit we want and connect to a node with BitTorrent, but once connected we conduct this Smart Protocol negotiation in an overlay connection on top of the BitTorrent wire protocol, in what’s called a BitTorrent Extension. Then the remote node makes us a packfile and tells us the hash of that packfile, and then we start downloading that packfile from it and any other nodes who are seeding it using Standard BitTorrent. We can authenticate the packfile we receive, because after we uncompress it we know which Git commit our graph is supposed to end up at; if we don’t end up there, the other node lied to us, and we should try talking to someone else instead." The project is, obviously, a new one that still has important ground to cover—such as dealing with comments or pull requests—but there are interesting ideas to consider already.

    Linux support for digital video broadcasting
    Mauro Carvalho Chehab, the maintainer of the kernel's media subsystem, has
    posted the first two in a series of articles on digital video broadcasting
    support in Linux. Part 1
    gives an overview of how the devices and protocols work, while part 2
    looks at digital TV network interface use. "Supporting embedded
    Digital TV hardware is complex, considering that such hardware generally
    has multiple components that can be rewired in runtime to dynamically
    change the stream pipelines and provide flexibility for things like
    recording a video stream, then tuning into another channel to see a
    different program. This article describes how the DVB pipelines are setup
    and the needs that should be addressed by the Linux Kernel.
