BZip3: A Superior Successor to BZip2

2025-02-01

BZip3: A Superior Successor to BZip2

BZip3 is a faster and more efficient successor to BZip2, boasting higher compression ratios and improved performance. This is achieved through an order-0 context mixing entropy coder, a fast Burrows-Wheeler transform utilizing suffix arrays, and an RLE with Lempel Ziv+Prediction pass based on LZ77-style string matching and PPM-style context modeling. Benchmarks comparing it against other compression algorithms, including tests on a massive archive of Perl source code, demonstrate its significant advantages. BZip3's performance is highly dependent on the compiler, with x64 Linux clang13 builds showing impressive speeds. The project is licensed under LGPLv3.

A Minimalist Ruby X11 Window Manager: rubywm

Frustrated with existing window managers, the author created rubywm, a minimalist window manager written in under 1000 lines of pure Ruby (including the X11 driver). It supports tiling and floating window layouts but lacks window decorations and drag-and-resize functionality. All keyboard handling is delegated to external tools like sxhkd, and communication happens via X11 ClientMessage events. Currently, it only supports single monitors and is experimental, prone to crashing. The author's primary goal is personal use, not a large user base.
