    Show HN: A zoomable timeline of 4M Wikipedia events
    I'm building a journal app in Kotlin Multiplatform and for this purpose I have created a zoomable timeline interface. This is a side-project where I reuse the timeline interface to display 4 million events imported from Wikipedia / Wikidata, scored using PageRank. There is more information on the about page. If you're interested in the stack: I use Kotlin Multiplatform extensively, with Compose Multiplatform for the UI, communicates with the backend using Kotlinx-RPC and behind the hood a simple

    Show HN: Simulator for a custom 8-bit discreet logic computer
    5 years ago, I made a derivative of SAP-1 (mainly inspired by Ben Eater) on breadboard with few improvement and called it MSAP-1 ( https://github.com/mehrantsi/MSAP-1 ) I made my own very primitive Assembly language and a simple Arduino programmer ( https://github.com/mehrantsi/8-bit_CPU_Programmer ) where I could load my programs onto MSAP-1 and even Debug them ( https://github.com/mehrantsi/8-bit_CPU_Debugger ). After that I started worked on the second version of it ( https://github.com/mehra

    Show HN: Clx – Compile Lua to Native Executables Through C++20
    Hi HN, clx is an ahead-of-time compiler for standard Lua that generates C++20 and produces standalone native executables through GCC, Clang or MSVC. The project started as an experiment to see whether modern C++ could be used as a portable compiler backend instead of LLVM or direct machine code generation. The generated code is then compiled and optimized by the host toolchain. The latest release replaces the previous NaN-tagged value representation with a new shadow-types implementation, adds f

    Show HN: Leaves – A text-UI disk usage treemap visualizer
    GUI disk analyzers are great for figuring out what's filling up your laptop/desktop drive. On containers or remote servers, the options are limited to purely text based utilities (e.g. du) or list-centric TUIs (e.g. ncdu) which are usually limited to viewing one directory at a time. I created leaves to fill that gap. Inspired by classic utilities like WinDirStat and KDirStat, it uses a 2-dimensional treemap^1 visualization to show the entire directory hierarchy with proportionally sized rectangl

    I've written Mojibake because I don't like the other Unicode libraries for Unicode support. It consists of only two amalgamation files: mojibake.h and mojibake.c. I've added all the most important Unicode algorithms, such as normalization, case conversion, segmentation, bidirectional text, collation, confusable, and others. I regularly test it in these OSes: Linux, macOS, FreeBSD, OpenBSD, NetBSD, and Windows 11. You can find a WASM demo on that site of all the public API functions and the docum

    After six months of work, I am here again presenting Fluent – a tiny lang which is optimized for differentiable & reactive programming. Since I am not Conal Elliot, don't expect a beautiful theoretical unification of FRP and AD from first principles. Rather, a horrific monster that holds together mostly because a lot of duct-tape. The link points to the semi-interactive tour of the language, which will get the job done much better than I could in here. Hope you hate/like it!

    6 months ago [0] I did a Show HN for Docket - it’s a system for active note taking in regular meetings like 1-1s, stands, all-hands, etc. On that thread a few of you asked for a self-hosted version. So I built it. There's a free tier available. I put loads of effort into making setup easy - just one install command that gives you a CLI for start/stop/upgrade commands etc. It runs as a single container, you can use a custom domain out the box for hosting over the internet (it provisions a LetsEnc

    Show HN: Lific: Issue trackers should be simple, right?
    I built Lific because I direct AI coding agents on largish projects and needed somewhere for project state to live that isn't markdown files in the repo. When I was begging to work on long horizon ideas, I started on Linear, but my agent files issues faster than a human does, and I hit their limits and pricing wall almost immediately. Then I self-hosted a popular open source tracker which meant running its 13 containers, and its MCP integration was 30k tokens and I got so fed up that I eventuall

    Show HN: misa77 - a codec that decodes 2x faster than LZ4 (at better ratios)
    I've spent the last few months working on this codec. It has the following characteristics: - SOTA decompression throughput in its ratio class - Decent ratios (comparable to LZ4 at high effort levels) - Slow compression Most of the gains can be attributed to reducing branches and making decompression very friendly to out-of-order cores, by using a smart format. Results on the tarred Silesia corpus on Intel x86-64 follow: codec decode ratio encode misa77 -0 5219 MB/s 42.64% 54.5 MB/s misa77 -1 42

    Show HN: Libretto PR agents – Automatically fix failing playwright scripts
    Libretto PR agents is a free TypeScript library for maintaining Playwright browser automations. Add one line of code to your existing Playwright scripts and it lets an agent automatically open GitHub PRs fixing the script when it fails. A few months ago we released Libretto, a CLI + coding-agent skill for building deterministic browser automations. The idea was that for many browser workflows, especially repetitive business workflows, you don’t need an AI agent making decisions at runtime. You w

    Hi everyone, I’ve been building Proton to solve a specific pain point in the Go ecosystem: building native GUIs without the "web dev" trade-offs or CGO complexity. If you’ve tried to build desktop apps in Go, you’ve likely dealt with the frustration of CGO dependencies, bloated build pipelines, or feeling like you’re just writing a thin wrapper around a browser. Proton aims to fix this with a clean, pure-Go approach: Zero CGO: Cross-compile to Windows and macOS seamlessly from any machine. Immed

I spent many hours playing (and studying and editing) QBasic Gorillas, and this is a vanilla JS implementation using Fable and Opus. Play 1-on-1 hotseat or against the computer. A bit of extra camera snazz as well.

Finally, we made something that we wanted ourselves: a self-directed programming retreat, where people built fun projects, contributed to open source, and helped eac

    Ask HN: Add flag for AI-generated articles
    Should HN add the ability to flag articles as AI-generated? This doesn't have to act as a regular flag, i.e., it won't de-rank the article; it could just show up as an indicator, allowing others (like myself) who don't like reading AI-generated text, to skip it. Open questions: 1. Why is the regular voting system not enough? 2. Should HN change in response to the gen AI era? It has been successful not changing fundamentals.
