    ARITA

    ARITA

    Extraordinary audio player for FreeBSD & GNU/Linux

    Unlike conventional audio players, ARITA aims to help music lovers to keep their precious collections well organized and tidy. Therefore it takes a different approach to arranging audio files. They must be emplaced into libraries: 'archives' or 'cuesheets'. Archive - compressionless container like CPIO. Instead of tags for description of tracks, a plain XML/YAML file is placed alongside each archive. Rather than embedding cover art in every track, put a single image next to a library. TIFF supports multipage docs, so scans of covers/discs can be packed together in one file. ARITA will locate and display the said file, allowing you to view all pages. Optional 'signature' files can be created to keep checksums of tracks, so you may ask ARITA to verify them and make sure nothing is damaged due to a sudden failure of HDD/SSD. As for 'cuesheets': tracks are merged into a single continuous audio file and a supplementary text file, which provides information on where tracks start and end.

    STMX

    High-performance transactional memory for Common Lisp

    STMX is a high-performance Common Lisp library for composable Transactional Memory (TM), a concurrency control mechanism aimed at making concurrent programming easier to write and understand. Instead of traditional lock-based programming, one programs with atomic memory transactions: if a memory transaction returns normally it gets committed, if instead it signals an error (Lisp slang for throwing an exception) it is rolled back. Memory transactions can safely run in parallel in different threads, are re-executed from the beginning in case of conflicts or if consistent reads cannot be guaranteed, and effects of a transaction are not visible from other threads until it commits. STMX gives freedom from deadlocks, automatic rollback on failure, and it aims at resolving the tension between granularity and concurrency.
