Headroom is an AI gateway proxy and token optimizer designed to reduce the cost and latency of large language model interactions. It functions as an intermediary that intercepts traffic between clients and providers to apply context compression, request routing, and format translation. The system differentiates itself through a Model Context Protocol server implementation that delivers compression and retrieval tools to compatible AI hosts. It employs a content-aware compression pipeline and tiered importance scoring to trim redundant data from logs and tool outputs while preserving essential

This project provides a lossless compression algorithm and a byte-oriented compression library designed for high-speed data reduction and maximum decompression speed. It functions as a stream-oriented compression engine, a software library for encoding and decoding data blocks, and a command-line tool for managing interoperable compressed frames. The system distinguishes itself through the use of predefined pattern dictionaries to improve compression ratios for small data sets and small packets. It supports multiple processing modes, including high-speed block compression for minimal latency

MAME is a vintage hardware emulation platform designed to recreate the circuitry of arcade games, computers, and consoles to run original software on modern devices. It functions as a retro gaming preservation framework for managing, verifying, and archiving ROM sets and disk images to ensure long-term software accessibility. The project features a system debugging tool for inspecting emulated memory, CPU registers, and execution flow via breakpoints and disassembly. It also includes a Lua-based automation layer that exposes core system state and hardware controls for custom behavior and anal

VimR is a native macOS graphical user interface for the Neovim editor. It wraps the Neovim binary within a Swift and AppKit application to provide system-level window management and OS integration. The application includes a project workspace manager for organizing files and windows into distinct contexts, a graphical file browser for navigating directory structures, and a fuzzy file searcher for locating files using approximate string matching. It also features a markdown and HTML previewer with synchronized side-by-side scrolling.

Mozjpeg is a high-performance C library for encoding, decoding, and transcoding JPEG images. It serves as a binary-compatible, drop-in replacement for standard JPEG libraries, maintaining existing function signatures to improve compression efficiency without requiring changes to application logic. The library functions as an image optimizer that reduces file sizes through lossless progressive encoding and coefficient optimization. It utilizes trellis-based quantization and SIMD-accelerated processing to optimize the trade-off between visual quality and file size. Its broader capabilities inc

PiShrink is a disk image shrinking tool and Linux filesystem optimizer. It reduces the size of disk images to their minimum requirements and configures the filesystem to automatically expand to the full capacity of the storage medium upon the first boot. The utility provides parallel image compression, utilizing multiple CPU cores to apply gzip or xz compression to large disk image files. It also includes filesystem error repair capabilities to resolve corruption that may otherwise block the shrinking process. The project covers disk image optimization and management, focusing on reducing st

Ouch is a command-line archive utility designed for compressing and decompressing files across multiple formats, including zip, tar, 7z, and zstd. It functions as a secure archive processor that sanitizes metadata to prevent path traversal attacks and terminal injection during extraction. The tool features a chain compression pipeline that allows for the sequential application of multiple compression algorithms by parsing chains of file extensions in a filename. It also includes a dedicated accessibility mode that optimizes terminal output for screen readers and text-to-speech technologies by

SharpCompress is a fully managed C# library to deal with many compression types and formats.

rdpwrap is a set of system utilities and services designed to enable, configure, and manage remote desktop protocol access and video compression settings. It functions as a service and manager that allows remote desktop connections on operating system versions where the feature is restricted or disabled by the vendor. The project provides tools to override system-level restrictions for remote access and activate remote desktop protocol services on unsupported versions. It includes a configuration tool for managing H.264 video compression and encoding settings to balance visual quality, networ
