    ULib

    ULib

    C++ application development framework, to help developers create apps

    ULib is a highly optimized class framework for writing C++ applications. I wrote this framework as my tool for writing applications in various contexts. It is a result of many years of work as a C++ programmer. I think, in my opinion, that its strongest points are simplicity, efficiency, and sophisticated debugging. ULib is meant as a very lightweight C++ library to facilitate using C++ design patterns even for very deeply embedded applications, such as for systems using uclibc along with...

    bzip2

    bzip2

    A file compressor/decompressor utility

    bzip2 is a free and open-source file compression program that uses the Burrows–Wheeler algorithm. It only compresses single files and is not a file archiver. It is developed and maintained by Julian Seward. Seward made the first public release of bzip2, version 0.15, in July 1996. The compressor's stability and popularity grew over the next several years, and Seward released version 1.0 in late 2000.

    BinDiff

    Helper app for VMware .vmdk files differential backup

    This application is intended to make a diff files for the backup purposes. Imagine that you have a VM with 10GB vmdk file that you backup every day. So, you need to keep 100GB (let say 60GB with compression) for 10 days. However from those 10GB file only ~500MB is daily changed and you can shrink your backup storage to 15GB, if you keep only the daily difference. The BinDiff makes this job for you. Initially you make a full copy of vmfk file (let's say every month or two). That time you also make a hash file to track the block changes. ...

    WOFF2

    WOFF2

    This document documents how to run the compression reference code

    woff2 is Google’s reference implementation of the WOFF2 webfont format, the modern, highly compressed container used by browsers to ship OpenType/TrueType fonts efficiently over the network. It integrates specialized transforms for font tables (like glyf/loca and variations data) with Brotli compression to squeeze out as many bytes as possible while preserving exact font fidelity on decode. The repository includes a compact C/C++ library and small command-line tools so you can convert existing TTF/OTF files to WOFF2 and back for testing or build pipelines. Its encoder applies deterministic, spec-compliant transformations that maximize compressibility without altering rendering results, making it safe for production web delivery. ...

    Lepton is a tool and file format for losslessly compressing JPEGs

    Lepton image compression, saving 22% losslessly from images at 15MB/s. Lepton achieves a 22% savings reduction for existing JPEG images, by predicting coefficients in JPEG blocks and feeding those predictions as context into an arithmetic coder. Lepton preserves the original file bit-for-bit perfectly. It compresses JPEG files at a rate of 5 megabytes per second and decodes them back to the original bits at 15 megabytes per second, securely, deterministically, and in under 24 megabytes of memory. ...

    intzip

    Fast compression of integer sets.

    ...The main focus of the algorithm is to encode structural characteristics of a given list, such as coherent intervals and repeated distances. Therefore, the quality of compression depends on diversity rather than size. In most cases, IntZip is able to achieve much better compression results than general compression algorithms on such data sets.
