BeleniX is a distribution based on the version of OpenSolaris that runs on x86 machines. It comes as a live CD and includes all of the OpenSolaris components (core kernel, libraries, and utilities) and also includes additional GNU/OSS software. BeleniX is a full fledged OS distribution that can be installed and used as a regular desktop system.
Pcompress is an archiver that can do compression/decompression and deduplication in parallel by splitting input data into chunks. It has a modular structure and includes support for multiple algorithms like LZMA, Bzip2, PPMD, LZ4, etc., with KECCAK/BLAKE2/SHA-256/512 chunk checksums. SSE optimizations for the bundled LZMA are included. It also implements chunk-level Content-Aware Deduplication and Delta Compression features based on a Polynomial Fingerprinting scheme. It has low metadata overhead and overlaps I/O and compression to achieve maximum parallelism. It has AES encryption capability and uses Scrypt from Tarsnap to generate per-session unique keys from passwords. It can work in pipe mode, reading from stdin and writing to stdout. It also provides some adaptive compression modes in which a suitable algorithm is chosen per chunk based on heuristics.
