Show HN: go-binsync – Go binary patches up to 67× smaller than bsdiff This project is a little performance-optimization experiment focused on reducing the size of Go binary patches, which can be useful for quick incremental updates of live services. When a Go program grows by a few bytes through an incremental change, a bunch of related references and offsets throughout the compiled binary end up changing that makes general-purpose binary-diff encoders inefficient: `zstd --patch-from` produces a 530kb patch for a one-line change in a 30MB binary. bsdiff improves upon this (150KB patch) thanks to a delta compression algorithm that can handle relative offsets. go-binsync goes a step further for Go binaries by borrowing an idea from Courgette, the technique Google uses to ship Chrome updates: read the structure the compiler left behind, predict the expected results from that structure, and send only the correction. Courgette gets that structure by disassembling; go-binsync gets more detailed Go-specific structure from additional metadata embedded in every compiled Go binary. The end result is a 2,262-byte patch for the one-line change, or a 67× improvement over the bsdiff result. Still just a proof of concept (no CGO, no debug symbols, amd64 only) but I thought others might find the initial results interesting. I think this predictive-encoding approach could be generalized beyond Go binaries to efficient compression in other domains where some kind of specialized predictive structure is available. https://ift.tt/UflNzZG August 28, 2026 at 01:17AM

Show HN: Voronoi Go https://ift.tt/tnUedqh

Show HN: Voronoi Go I posted once before but wanted to share again because a lot has changed. There's now a fairly strong bot to play against (contributed by a community member) and also correspondence games. The combination of these things helps a bit in finding people to play against. https://voronoigo.com/ August 27, 2026 at 11:33PM

Show HN: Convolens – Real time slides and fact-checking https://ift.tt/xzIrsJM

Show HN: Convolens – Real time slides and fact-checking Convolens is a Mac desktop app that records and transcribes your conversation on device, and turns it into slides, fact-checks, and infographics. I built the real time slides because I'm constantly losing focus during meetings and needed something I can quickly glance at and know exactly where I'm at and what happened during my "snooze". As a whole, Convolens lets you: - Record and transcribe your meetings / sessions locally. - Generate Slide decks, Infographics, and Fact-checks from your conversation (among other things). - Chat with your meeting/session and research anything that you need. Anyway, please check out the app we have a great free tier. Any and all comments are greatly appreciated! https://ift.tt/IYSrHwc August 27, 2026 at 01:20AM

Show HN: I made a Raspberry with Qwen my local car AI https://ift.tt/RjpnxgM

Show HN: I made a Raspberry with Qwen my local car AI Found that you can actually run a 35B Qwen model on a Pi with very impressive intelligence and stability. Built connectors for car ODB to read all about car internals, and manufacturer's cloud service for stuff like changing AC or opening/ locking doors. Gave it info such as the full car manual. And then hooked it up with my other agents in our discussion room! So now it can answer car questions such as "when should I add oil and what kind of oil?" and help you fully offline, and when online talk with the agent family that includes all the most powerful models so they know how the car is, plan new features and develop itself with them. For example, if car breaks and can't move the car agent informs my agent family and they can already look for a suitable train ticket without me needing to check things or do something. https://ift.tt/jBSsEwo August 25, 2026 at 08:50PM

Show HN: Civic Nightmare –Browser JRPG about a citizen in a savage civilization https://ift.tt/SyGEq1h

Show HN: Civic Nightmare –Browser JRPG about a citizen in a savage civilization Observing the world as it turns, I created Civic Nightmare, a small browser-based JRPG that explores the absurdity of contemporary politics. I've included many characters such as: Trump, Putin, Macron, Lagarde, Musk, etc., who become characters within the same surreal world, with different dialogues and minigames built around their public personas and none of them is really spared. The game runs in the browser, was created with Godot, and is open source (contributions are welcome). It's a small experiment, but I'm happy to continue it; ultimately, it portrays a simple citizen in the midst of a savage civilization. https://ift.tt/ULBrHj7 August 23, 2026 at 11:40PM

Show HN: Traccia - Observability, Runtime Control & Audit for agents https://ift.tt/4tdJ7zW

Show HN: Traccia - Observability, Runtime Control & Audit for agents AI applications are becoming agents, which has started to take autonomous decisions. There are plenty of tools and platform available to trace, and observe what an agent or llms calls does. They are good in what they do, but tracing and observability isnt enough for AI agents era. We need a solution that can help you observe, evaluate, create run time policies to govern and finally audit the actions of the agent. We built Traccia to solve this problem. The good part, all of these can be achieved by just writing few lines of code. Traccia has an open-sourced sdk that can work with your existing observability tool like grafana, tempo, jaeger, etc. In case you need more than just observability, Traccia provides the platform to evaluate, control and audit the agents. The platform is easy to use. The product's documentation is quite extensive. It is also cloud vendor and framework agnostic. Traccia is being built by an Indian start up ,based out of Bengaluru. We are running a 3 months free trials so that you can explore without any strings attached. We are open to improvise and get better so please drop your comments and feedbacks. https://traccia.ai/ August 21, 2026 at 11:50PM

Show HN: Interactive map of the Odyssey with tap-to-gloss Homeric Greek Built an interactive atlas of Odysseus's voyage. See where the stops fall in today's world, with etymological and knowledge nuggets. 17 stops from Troy to Ithaca. Every stop has Homer's actual Greek (Perseus TEI), Murray's 1919 translation, and every single Greek word is tappable for a translation. Press N and the ancient chart swaps to today's satellite view: these are real places (e.g. Scylla refers to a town called Scilla in Calabria). Stack: SvelteKit static + MapLibre, no backend, all public-domain texts and art with a full colophon. Please leave corrections and feedback! https://ift.tt/5XgOK21 August 21, 2026 at 11:41PM
