    Hello, I would like to share a Rust implementation of the Zstandard seekable format I've been working on. Regular zstd compressed files consist of a single frame, meaning you have to start decompression at the beginning. The seekable format splits compressed data into a series of independent frames, each compressed individually, so that decompression of a section in the middle of an archive only requires zstd to decompress at most a frame's worth of extra data, instead of the entire archive. I started working with the seekable format because I wanted to resume downloads of big zstd…

    I am a developer. I have been building stuff for the last 13 years. One common challenge in all my projects is compressing assets to make them as small as possible. I used to end up using online compressors, but this has a lot of privacy concerns. So, I finally set down for couple of weeks and built this simple app. I can just drag and drop assets in it and it shrinks them. It currently supports around 25 file types. I built a lot of iOS apps but this is the first time building a macOS app, so any feedback is welcome.

    I built an experiment that uses an overfitted transformer and arithmetic coding to compress individual files. Instead of training the model to generalize, I train a 900KB transformer to memorize a single file and predict the next byte. Those predictions are fed into an arithmetic coder to produce the compressed output. On a 100MB NYC taxi CSV, it compresses to about 7MB (~0.5 bits/byte). On a 100MB slice of enwik9, it compresses to about 21MB (~1.68 bits/byte). It's pretty slow right now (roughly 20–30 minutes of training and 45 minutes each for compression and decompression on my…

    Hello HN, author here. I built ZXC, a lossless compression library designed specifically for "Write Once, Read Many" scenarios (Game assets, Firmware, App bundles). The Concept: Standard real-time codecs (LZ4, Snappy) are designed for symmetry. ZXC explores an asymmetric approach: it spends significantly more CPU cycles at compression time to generate a bitstream specifically structured for modern, wide-issue execution pipelines (maximizing Instruction Level Parallelism). Performance (Verified via lzbench integration): ZXC was merged into the official lzbench repository monday. ARM64 (Apple…

    Hey HN! My friends and I built a new platform for generating images. The app is easy to use for people who find ComfyUI hard to use, or just simply don’t have a GPU to use it on. For those not familiar, ComfyUI is a great tool for using open-source models like Stable Diffusion. It’s primarily great because it’s a node-based tool, which means you can chain together models, upscalers, prompting nodes, etc… which let you create images in the exact aesthetic you want. There’s also a vibrant dev community behind ComfyUI, which means that there are a ton of nodes and customizability. We’re users…

    Facebook's Katran looked too scary (and I don't do C++), so I thought I would investigate using XDP&#x2F;eBPF to redirect packets at high speed and Go to do the control plane work of health-checking backed servers and managing configuration. With luck the resulting binary should be easy to deploy by non-developers. It's still not mature, but seems to work. Code was written in a very exploratory manner, and I'm not a developer so it is quite shocking at the moment, but I aim to improve it. It is intended to be horizontally scalable with ECMP and has been tested on service providing…
