    Lossless Claw

    Lossless Claw

    LCM (Lossless Context Management) plugin for OpenClaw

    Lossless Claw is an advanced context management plugin for the OpenClaw agent ecosystem that redefines how conversational memory is handled in large language model systems. Instead of relying on traditional sliding-window truncation or lossy summarization, it introduces a lossless architecture that preserves all historical messages while maintaining usable context within token limits.

    LosslessCut

    LosslessCut

    The swiss army knife of lossless video/audio editing

    ...Or you can add a music or subtitle track to your video without needing to encode. Everything is extremely fast because it does an almost direct data copy, fueled by the awesome FFmpeg which does all the grunt work. Lossless merge/concatenation of arbitrary files (with identical codecs parameters, e.g. from the same camera). Lossless stream editing: Combine arbitrary tracks from multiple files (ex. add music or subtitle track to a video file).

    lsfg-vk

    lsfg-vk

    Lossless Scaling Frame Generation on Linux

    The lsfg-vk project is a Vulkan layer developed primarily by PancakeTAS that hooks into Vulkan-based applications to enhance rendering by generating additional frames using the Lossless Scaling frame generation algorithm originally associated with the Lossless Scaling project. Instead of relying on driver-specific or hardware-accelerated upscaling, this layer intercepts Vulkan API calls and injects frame interpolation on the fly, effectively producing smoother motion in supported games and applications by creating synthetic intermediate frames. ...

    Brotli

    Brotli

    Brotli compression format

    ...This happens when "one-shot" decoding API is used (or input chunk for streaming API is not limited), input size (chunk size) is larger than 2GiB, and input contains uncompressed blocks. After the overflow happens, memcpy is invoked with a gigantic num value, that will likely cause the crash. Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression. The specification of the Brotli Compressed Data Format is defined in RFC 7932. ...

    simdjson

    simdjson

    Parsing gigabytes of JSON per second

    JSON is everywhere on the Internet. Servers spend a *lot* of time parsing it. We need a fresh approach. The simdjson library uses commonly available SIMD instructions and microparallel algorithms to parse JSON 4x faster than RapidJSON and 25x faster than JSON for Modern C++. The simdjson library uses three-quarters less instructions than state-of-the-art parser RapidJSON. To our knowledge, simdjson is the first fully-validating JSON parser to run at gigabytes per second (GB/s) on commodity...

    Lidarr

    Lidarr

    Looks and smells like Sonarr but made for music

    ...It continuously monitors RSS feeds for new releases from your favorite artists, automatically retrieves them, sorts files into your library, and ensures consistent naming and tagging so your collection stays tidy and accessible. The tool also supports quality upgrades: if a better version of a track becomes available (for example, a lossless format), Lidarr can automatically fetch and replace lower-quality files, saving you manual effort. Integrated with many popular download clients and indexers, users can customize how Lidarr interacts with their existing setup for optimized automation. Built with a user-friendly web interface, it works cross-platform on Windows, macOS, Linux, and NAS systems, and can also run as a Docker service for containerized environments.

    DFlash

    Block Diffusion for Ultra-Fast Speculative Decoding

    ...It acts as a β€œdrafter” that proposes likely continuations which the main model then verifies, enabling significant throughput gains compared to traditional autoregressive decoding methods that generate token by token. This approach has been shown to deliver lossless acceleration on models like Qwen3-8B by combining block diffusion techniques with efficient batching, making it ideal for applications where latency and cost matter. The project includes support for multiple draft models, example integration code, and scripts to benchmark performance, and it is structured to work with popular model serving stacks like SGLang and the Hugging Face Transformers ecosystem.

    JLD.jl

    JLD.jl

    Saving and loading julia variables while preserving native types

    ...JLD is a specific "dialect" of HDF5, a cross-platform, multi-language data storage format most frequently used for scientific data. By comparison with "plain" HDF5, JLD files automatically add attributes and naming conventions to preserve type information for each object. For lossless storage of arbitrary Julia objects, the only other complete solution appears to be Julia's serializer, which can be accessed via the serialize and deserialize commands. However, because the serializer is also used for inter-process communication, long-term backward compatibility is currently uncertain. (The JLDArchives repository exists to test the compatibility of older JLD file formats.) ...
