    rav1e is an open-source implementation of an encoder for the AV1 video codec, developed in Rust (with some assembly) by the community around Xiph Foundation. Its design philosophy is to start from a correct, minimal, and fast AV1 encoder — sacrificing some encoding speed/efficiency of reference encoders in exchange for simplicity, stability, and compilability across platforms — and then gradually improve.

    spleen

    Monospaced bitmap fonts

    Spleen started as a personal challenge. Patrick Wildt (patrick@) recently imported ssdfb(4), a driver for small OLED displays in OpenBSD and needed a 5x8 font to be able to squeeze more columns and rows on those devices. As someone spending most of his time in a terminal, I have been thinking about drawing my own font for a while, and this was the perfect opportunity. To be able to test character spacing and alignment, I started to use the font in xterm, then a zoomed version, and one thing...

    Tool to remap Caps Lock key behavior on Windows systems

    Capslock is a command-line tool for analyzing the capabilities of Go packages to reveal what privileged operations their code and dependencies can perform.
