    Hi HN! I wrote a small program to browse folders in the terminal. The main inspiration was type-ahead search in GUI file managers. There exist several programs that are similar (see the listing in the README), but none of them do it quite the way I like, and often they have a very complex UI and a ton of features. I tried to make something that is obvious how to use and gets out of your way. (I also wanted an excuse to learn Rust.) Let me know what you think!

    forkrun is the culmination of a 10-year-long journey focused on "how to make shell parallelization fast". What started as a standard "fork jobs in a loop" has turned into a lock-free, CAS-retry-loop-free, SIMD-accelerated, self-tuning, NUMA aware shell-based stream parallelization engine that is (mostly) a drop-in replacement for xargs -P and GNU parallel. On my 14-core/28-thread i9-7940x, forkrun achieves: * 200,000+ batch dispatches/sec (vs ~500 for GNU Parallel) * ~95–99% CPU utilization across all 28 logical cores, even when the workload is non-existant (bash no-ops / `:`)…

    I built a Rust-based CLI/terminal UI for inspecting Parquet files—data, metadata, and row-group-level structure—right from the terminal. If someone sent me a Parquet file, I used to open DuckDB or Polars just to see what was inside. Now I can do it with one command. Repo: https://github.com/kaushiksrini/parqeye

    Hello Everyone, I'm excited to introduce a new open-source observability platform and would love to hear your feedback. We are aware that there are lots of open-source/commercial tools out there. However, we believe that monitoring the clusters and extracting actionable insights requires deep know-how about the tools/domain. We mainly focused on this problem. - Alaz is an eBPF agent installed on your K8s cluster as DaemonSet. Thanks to eBPF, Alaz collects traces directly from Linux kernels. This means there's no need for sidecars, instrumentations, or service restarts. - The UI not…

    A lightweight engine for durable execution / deterministic workflows I built with Rust, wasmtime and the WASM Component Model. Its main use is running reliable, long-running workflows that can automatically resume after failures. Looking for feedback on the approach and potential use cases!

    Hi! I just made an obsdian alternative in terminal after searching for an Obsidian like TUI and got nothing. So I built one myself.

    I have posted a much earlier version of this over a year ago [0]. Since then a lot has changed. Obviously, the name has changed. This happened for the paper publication [1]. I have also optimized the speed, integrated ISA-L for special cases, limited the compression-ratio-dependent maximum memory consumption, and finally added parallelized CRC32 computation, which adds ~5% overhead no matter the number of cores used. At this point, I am leaning towards calling it production-ready although there are still many ideas for improvements. Redoing the benchmarks of the older Show HN, would look…

    Made an ARM Thumb CPU from scratch in a digital circuit simulator for fun and decided to push the joke a little further and run real stuff on it, like a Web server, a Scheme interpreter, a MIDI player, and a VT100 emulator. This is basically a how-did-we-get-here blogpost, it's my second one of this kind, I'd love any feedback you might have.

    Hi HN, author here. I built Tylax because I wanted to migrate my old LaTeX papers to Typst but found existing regex-based scripts too fragile for nested environments. Tylax parses LaTeX into an AST (using mitex-parser) and converts it to Typst code. It supports: - Full document structure (not just math snippets) - Complex math (matrices, integrals) - Experimental TikZ -> CeTZ graphics conversion - Runs in browser via WASM Repo: https://github.com/scipenai/tylax Web Demo: https://convert.silkyai.cn/ Happy to answer any questions!

    Hello HN, I'm very excited to have finished a gzip decoder that can speed up decompression using threads. On my Ryzen 3900X, I measured a 8x speedup over standard gzip, reaching 1.6 GB/s for a synthetic file with a consistent compression ratio of 1.3. A functional decompressor like this is kind of a first, that's why I am excited. Pragzip implements the two-staged decompression idea put forward with pugz, which unfortunately only works with gzipped text files not arbitrary files and has many more limitations. I think my main contribution over pugz might be a fast (~10 MB/s)…

    Hi, over the past few months I've been working on this project: Numax is a small Rust runtime that does three things: it runs WebAssembly modules in a sandbox, has a built-in local key-value store, and syncs everything across nodes with CRDTs and gossip. Basically, you write a wasm module, run it on two machines, and they converge (I hope !). It's a decentralized system... I hope someone finds it interesting! There's a whitepaper I've put a lot into, and I think the code isn't bad either! I believe there's still room in this world for software that's fun and well made, and while building…
