    libpostal

    libpostal

    A C library for parsing/normalizing street addresses around the world

    ...Addresses and the locations they represent are essential for any application dealing with maps (place search, transportation, on-demand/delivery services, check-ins, reviews). Yet even the simplest addresses are packed with local conventions, abbreviations and context, making them difficult to index/query effectively with traditional full-text search engines. This library helps convert the free-form addresses that humans use into clean normalized forms suitable for machine comparison and full-text indexing. Though libpostal is not itself a full geocoder, it can be used as a preprocessing step to make any geocoding application smarter, and simpler.

    brightnessctl

    brightnessctl

    CLI tool to read and control screen and LED brightness on Linux system

    brightnessctl is a lightweight command-line utility written in C that enables users to read and control device brightness on Linux systems. At its core, the tool interacts with brightness interfaces exposed by backlight and LED devices, making it possible to query current brightness, adjust levels, and even restore previously saved states. By default, brightnessctl searches relevant device classes for available brightness controllers and, if no device is specified, automatically selects the first one it finds. This functionality is especially useful for managing screen backlight or LED brightness on laptops and embedded devices without needing heavy graphical tools. ...

    OverServer

    OverServer

    Simple meta-server for locating other multiplayer servers

    ...One particular strength of the player-hosted games setup is that it places the burden of Internet traffic on the player base and not a central server. OverServer tries not to violate this strength by keeping the query and response length very low to cut down on overhead from running the metaserver. I designed OverServer with a few lessons in mind from Valve and Won's metaserver setup for Half-life. It is at least somewhat resistant to attack through a challenge-response system for incoming requests. I also wanted the tool to be very simple to "snap in" to an existing application.
