The weekly GitHub Reflog highlights notable repositories and community activities, with recent editions now available in Russian thanks to Alexander Marshalov's efforts. This week's featured repository is yostudios/Spritemapper, a Python-based command-line tool that generates CSS sprites using advanced techniques. Other notable projects include jstrait/beats, a Ruby-written audio sequencer utilizing YAML for song programming, and tweetdeck/TDOAuth, a streamlined OAuth v1.0 implementation for iOS. The Reflog also showcases innovative tools like SWFREtools for Flash security audits, Microsoft's Azure library for iOS, and wbsun/kgpu for GPU-based computation in Linux. Promising projects include a Vim plugin for CSS color highlighting, a script for domain blocking, and an esoteric project running Perl on the Go stack. The Reflog invites feedback and tips, with additional open-source news available on The Changelog and GitHub Explore.
