In this episode of the Late Night Linux podcast, several exciting topics are explored. First up is PUP, a command-line tool designed for parsing HTML. Then, there's 8-bit Workshop, a web-based IDE that lets you create software for retro 8-bit systems. The episode also highlights a documentary from Valve celebrating the 20th anniversary of Half-Life 2, along with a project focused on reverse-engineering the protocols of smart Rubik's Cubes to create an open-source alternative. Additionally, the hosts discuss extensive battery life testing across various Linux desktop environments—XFCE, MATE, Plasma, and GNOME—on different hardware. The findings reveal that newer hardware shows more pronounced differences in battery performance among the environments, with GNOME on Wayland generally leading the pack, though the results are nuanced and warrant further investigation.
