    Zstandard

    Zstandard

    Zstandard - Fast real-time compression algorithm

    ...Zstd can trade compression speed for stronger compression ratios. It is configurable by small increment. Decompression speed is preserved and remain roughly the same at all settings, a property shared by most LZ compression algorithms, such as zlib or lzma.

    Reliable PostgreSQL Backup & Restore

    Reliable PostgreSQL Backup & Restore

    Reliable PostgreSQL backup and restore

    pgBackRest aims to be a reliable, easy-to-use backup and restore solution that can seamlessly scale up to the largest databases and workloads by utilizing algorithms that are optimized for database-specific requirements. Compression is usually the bottleneck during backup operations but, even with now-ubiquitous multi-core servers, most database backup solutions are still single-process. pgBackRest solves the compression bottleneck with parallel processing. Utilizing multiple cores for compression makes it possible to achieve 1TB/hr raw throughput even on a 1Gb/s link. ...

    Snappy

    Snappy

    A fast compressor/decompressor

    ...On a single core of a Core i7 processor in 64-bit mode, it compresses at about 250 MB/sec or more and decompresses at about 500 MB/sec or more. (These numbers are for the slowest inputs in our benchmark suite; others are much faster.) In our tests, Snappy usually is faster than algorithms in the same class (e.g. LZO, LZF, QuickLZ, etc.) while achieving comparable compression ratios.

    NTK Ultra-Compression

    NTK Ultra-Compression

    Logiciel de compression de fichiers maximal indépendant du temps.

    Le logiciel NTK Ultra-Compression répond à une problématique essentielle de l’ère numérique : comment réduire la taille des données à leur minimum absolu sans compromis sur leur intégrité, tout en s’affranchissant des contraintes temporelles ? Dans un monde où les volumes de données explosent et où les solutions actuelles de compression restent limitées par des compromis entre rapidité, efficacité et complexité, nous proposons une approche disruptive. Les solutions actuelles, telles que...

    Burris Numerical System

    Burris Numerical System

    A Numerical System controlled by algorithms.

    BNS - Burris Numerical System was written to store the last digit of a number in 3 dimensional space but store the rest of the number mathematically in the 4th dimension of space. The result is that no matter how long the number is you can write it down on a piece of paper and put it in your pocket. The software can be used to retrieve the number. This can be used to save computer files. The only limit with BNS is how much time the user has. The software nor the numerical system has no...
