    SQZ – Low complexity, scalable lossy to lossless image compression▲7

    I'd like to share a little toy project of mine, a really simple image codec that can do lossy to full lossless image compression with complete scalability at a byte level granularity - you can compress an image just once, even fully losslessly if needed, and then get any lossy version possible by simply stopping decompression at any offset in the compressed data. This "encode onde, serve many" approach is especially interesting for providing downscaled low quality image previews (LQIP) in as tight a storage budget as possible, and then allowing seamless, transparent refinement as deemed…

    LimitPixel▲9

    I’ve spent the last year developing a decomposition kernel that addresses the "Linear Bottleneck" in standard compression (Zstd, LZMA, Brotli). The Problem: Traditional algorithms operate on 1D streams. They are blind to the spatial, temporal, or hierarchical architecture of modern data (3D models, nested JSON, multi-modal blobs). When you force these structures into a 1D window, you leave significant entropy on the table. The Solution: PXG v3.0 maps binary data to a 13505x13505 grayscale grid. By treating data as a coordinate system rather than a line, our engine utilizes adaptive tiling to…

    I made a OSS alternative to Weights and Biases▲6

    Hey HN! I made a completely open sourced alternative to Weights and Biases with (insert cringe) blazingly fast performance (yes we use rust and clickhouse) Weights and Biases is super unperformant, their logger blocks user code... logging should not be blocking, yet they got away with it. We do the right thing by being non blocking. Would love any thoughts / feedbacks / roasts etc
