Show HN: I made a Gemma 4 Mac app that names screenshots with local AI I made my first macOS utility app that ships with a bundled Gemma 4 model, specifically the Gemma E4B one. It made my app DMG have 5.3 GB in size, but I think it is a small size for the power that this free local model can provide. It runs fine on CPU, but can also run on Apple Silicon GPU, although I did not notice any performance improvements with GPU (tested on a M5 chip). I think these local lightweight and multimodal models will open multiple possibilities for new software tools where privacy is essential. https://snapname.app May 31, 2026 at 02:40AM

Show HN: Helios – what plug-in solar could generate for any address in Britain Plug-in solar panels (no electrician needed) have just become legal in the UK and will go on sale soon. Helios estimates how much electricity a typical installation could generate at a given address and what that's worth against your tariff. It uses UK government LIDAR data to reflect the actual skyline, so it knows whether there's a building or a hill blocking the sun. Caveats: - Outside LIDAR coverage (most of Scotland and Wales) it falls back to a synthetic horizon (less accurate). - Trees and recent developments (post-2022 or so) may not be in the data, and some address placements could be off (geocoding via OSM). Feedback on the shading model especially welcome. https://ift.tt/dbj97eB May 30, 2026 at 12:08PM

Show HN: An update to our long-turn FreeCiv experience So we have had quiet the journey here. So 70 days ago (aka 73 turns ago) I posted on HN sharing our FreeCiv deployment ( https://ift.tt/zVdWUaj ). FreeCiv is a great game, the clients is very buggy however. I'm using the GTK4 version, but a few others have opted for the QT variant. At some point, we might turn our focus to contributing to improving the client based on our experiences playing the game. We've since added a lot of little fun features: - The editor: you can write to the newspaper Editor and they /might/ publish what you write, quote you, or decide you're full of it and write an opinion piece slamming your reputation. The editor will also reach out to a few players, each turn, and ask for their input on current game matters. - The Intelligence Dashboard. People were forgetting what they were up to, so we added a dashboard showing the timeline of what happens per turn for your player. - beta the online map ...

Show HN: Open-Source AI Racing Harness Hi I'm Dan from Elodin, making an open source real-time capable flight software simulation. For AI Grand Prix contestants, the wait for the Round 1 virtual qualifier simulation has been grueling. If you’re competing, check out our simulation harness to tide you over, built to match the published competition constraints and message format. It runs against real Betaflight, which we learned requires at least 1000 sensor samples per second to run real-time correctly. The competition warranted introducing a new feature to generate the camera sensor directly in the simulation loop. Typically people connect to Unreal or similar game engine to create a camera sensor, which works well but is very heavy. For the simple needs of this challenge, creating sample directly in the loop is very handy and easy to use. Happy to hear your feedback on this! While it's not fancy looking currently, it uses the Rust Bevy game engine, which should allow us to impr...

Show HN: Stumbleback – StumbleUpon for the bookmarks you've been hoarding Hi HN, I have about 2000+ bookmarks that I will never read. Probably you do too. I keep collecting new stuff to read, the list grows longer each day, but I barely get around to reading them, and the problem, as I realised, is more to do with the analysis paralysis on what to read. Sort of like how we spend so much time figuring out what movie to watch on Netflix. So I made a simple Chrome extension: it picks one bookmark at random, drops you on the page, and gives you two buttons on a floating toolbar - Stumble (next random one) or Done (mark read and move to the next random one). That's it. It takes away the burden of decision altogether, and it's sort of fun to engage with because of the variability (and novelty) of what it loads next, while still being within the universe of things I've been wanting to get to. Also, I've added daily goal and streaks to keep me motivated to get through the l...

Show HN: Posthorn, self-hosted mail without the mail server Introducing Posthorn, a self hosted email gateway. One docker container (or Go binary) between every self hosted app on your VPS and your transactional email provider. Set up Posthorn once, point your apps to it, done. I was trying to deploy Ghost on a DigitalOcean droplet and found that DO and many different VPS services have started to block the default SMTP ports to try to combat the various types of abuse they get. To actually configure my app, I had to hack together a Postfix relay. In another project, I had a static site which had a contact form, but my free Formspree account was occasionally hitting usage limits and I desperately wanted some of the anti-spam features they had gated behind their paid accounts so I put together a caddy module to catch HTTP POSTs and bounce them to my provider. I kept bumping into these same email issues. Many of the services I wanted to host (Gitea, Mastodon, Umami, Comentario) ran into t...

Show HN: SaveNeighbor – food delivery through your own personal network Hey everyone, the idea came to me when I got a food delivery from a woman who mentioned she had her children with her. I thought, I wish I could request her every time I get delivery, just for the feeling of knowing just who my tips are supporting. That was 4 years ago, being non-technical I didn't see myself getting it done. But thanks to Cursor and Chatgpt, SaveNeighbor is born. I know the model adds friction and the convenience is low until you build up a network, but that's kinda the point. Think of Ubers 'Wait and save', if you can be flexible you can save big on fees. And being able to choose who your money goes to is the biggest benefit in my opinion. Shoot me all your questions, I can't wait to hear your feedback. Thanks. https://ift.tt/9jZwiSU May 25, 2026 at 02:09AM

Show HN: Geomatic – a command-driven geometry studio enabled with autodiff All commands have the format `output = \func inputs` or just `\function inputs`. Points and scalars are built on the fly. Eg `\line a b` to an empty canvas creates points `a` and `b`, and joins them with a line. One can use broadcasting semantics similar to NumPy and PyTorch in a visual setting (imagine creating a list of circles where one dim corresponds to radius and another to the center). One can also use backpropagation, run gradient descent or visualize vector fields. Almost everything is reactive so changing a variable updates all of the downstream geometry. It also allows anyone to write and load their own visualization, which can be broadcasted and differentiated through. https://ift.tt/14PFdW5 May 25, 2026 at 09:25AM

Show HN: Twixt – transform one word into another in four moves I made this game while working on a different project about teaching English spelling. I was reading about homophones and got struck by how much a homophone can transform the shape of a word, so I started experimenting with little games built on that. I added a few more transforms, anagrams, verb/tense changes, but the answers kept coming out too obvious. I couldn't distort the word enough to make it interesting. The breakthrough was compound pairs. Jumping from one word to another through their compound (sea → horse, via seahorse) really obscures the path and that's when it suddenly got fun and unpredictable. I've been sharing it with friends. I'm in the UK so mostly UK testers, fair warning that a couple of the homophones may lean British. They've been playing daily and seem hooked, so it felt worth posting here. It's one puzzle a day mainly so I actually have time to hand pick puzzles that have a ...

Show HN: A platform to find people to jam on side projects with I have always found it funny how challenging it can be to find people to jam on side projects with. There are literally entire sub-Reddits where people post looking for someone to work on a project with. That is super inefficient. There are also newsletters for this (also pretty inefficient). Let's Jam is my attempt to solve this. This is NOT a cofounder matching platform. The idea is to connect people with ideas and skills so they can jam on them together. If they end up becoming cofounders, cool, but that is up to them. This is also NOT a place for freelancers to hunt job opportunities. Again, the platform is for people who have an idea or a skill and want to work on something together. How it works: > You either a) find a project and request to jam on it with that person, b) post a project and wait for someone to request to jam on it with you, c) claim an idea and wait for someone to request to jam on it with you...

Show HN: Free Fonts – a collection of 400+ original, open-source typefaces Hi HN! For the past few months I've been working up to this launch of Free Fonts - it's a collection of completely free, open source, and original fonts that can be used for any project, including commercial ones. The collection has over 400 fonts in a variety of novel styles, from simple sans serifs to decorative handwritten and blackletter fonts. It will also continue to be updated and grow over time. Designers and developers today have essentially two options when it comes to choosing and creating fonts. Either use a Google Font, which can be limited in terms of unique and novel selections, or pay a significant amount of money for font licenses from a few large players in the space like Monotype. The problem today is that it can be difficult to find a novel, unique font for an affordable price. Our hope is that this collection can be a starting point for solving this problem. What makes this project d...

Show HN: I made a tactical map-based WWII submarine simulator (public beta) I've seen quite a few simming discussions on HN, so thought some of you might like this - I've created a map-centered, tactical submarine simulator and it's been a blast to make. I grew up playing Silent Service II on Atari ST with my dad, then got into Silent Hunter IV in the 2000s, and most recently have been loving the more recent UBoat. In each case, the part I always enjoy the most is the plotting and charting aspect - essentially beating uncertain estimates with geometry. So I decided to see how far I could get making my own sim that focused nearly entirely on that aspect. You listen on the hydrophone, estimate course and speed, identify ships through the periscope to get the mast height, use a working stadimeter for range estimates, and then try to build a good enough firing solution before getting discovered and hunted by any escorts. Things I'm particularly proud of are the working stad...

Show HN: I reverse engineered Apple's video wallpapers Ever since Apple introduced their video wallpapers I wanted to be able to put custom videos there. I decided to reverse engineer and see what I can do. I built Phosphene to sell it, but the existing competitors were polished enough that the time it would have taken to catch up wasn't going to pay off. So I'm open-sourcing it. WallpaperExtensionKit.framework is what powers macOS wallpapers. It controls what’s shows in the Settings app. It took a lot of trial and error to replicate the behavior, but the result is that your custom wallpapers appear alongside everything else. I wanted to have an “add” button there too, but I couldn’t find a way to do so, so there’s a companion app that will put your video where it needs to be. Unlike Apple's Aerials, the video keeps playing on the desktop (not just the lock screen). The renderer drives AVSampleBufferDisplayLayer directly with PTS-offset gapless looping, and pauses or do...

Show HN: How to Kill the Dead Internet Ok, so maybe "how to revive the internet" would be more accurate, but if you're reading this, I got your attention, right? Here's why I want you to read on: I built a free extension, D-slop, to disincentivize anyone from posting AI writing, and eventually images and video as well, on the internet. For writing, it checks known vocab and punctuation tells, as well as subtler tells related to cadence, and assigns it a score subject to an adjustable threshold. If the text fails, users have the option to flag offending text, hide it, or block the page entirely (with the option to see anyway). For media, it's admittedly fairly weak, as it relies on C2PA metadata which is stripped from all of the social media sites where it would be most helpful. (Anyone else have chronically online boomer parents continually gobbling up slop like it's real information?) I have a D-slop+ version in the works that should be able to handle the med...

Show HN: Serene Bach – a Go weblog engine that runs as CGI or HTTP I originally made Serene Bach in the 2000s as a weblog engine written in Perl CGI. I rebuilt it from scratch in Go as a single binary that can run either as a CGI program or as a normal HTTP server. I know CGI is generally considered legacy technology now, but I still rely on it for shared hosting. In this version, I added Markdown support, a responsive default theme, Open Graph image generation, and static output generation. It is still in beta, but the repository includes a Docker image published on GHCR, documentation, and a local quick start. I'd appreciate feedback from anyone interested in small self-hosted publishing tools, especially if you still care about shared hosting or CGI-style deployment. https://ift.tt/wJNje8c May 17, 2026 at 04:47AM

Today I polished it up and added all the features that I need. It has file filters, search, an llm walkthrough mode, and review comments that you can paste back into your llm.

Show HN: NodeDB – High Perfomance Multi-Model Database Hey HN, I've been working on a multi-model database called NodeDB. Originally, i've found out the idea of SurrealDB quite good. However, it doesn't have some graph and vector features that I need. And since it is just a KV wrapper, instead of purpose-built engine, the performance will never be close to the specialized databases (like Neo4j, Pinecone, Clickhouse, etc). And i've asked myself, what if, there is a database that have the same idea, but built differently? Instead of just treating it as KV database, we build specialized engines for the data. Besides that, I want it to be able to support my IOT/edge project, where i need offline sync capabilities (Currentyl still in progress). Will it work? I put it into test. I've been experimenting and researching for a year, creating multiple versions, and then I created NodeDB.

On my own PRs, it has been catching dramatically more real bugs than Claude’s built-in /review, /ultrareview, CodeRabbit, Greptile, and Codex’s built-in review, while producing fewer false positives. adamsreview is six Claude Code slash commands packaged as a plugin: review, codex-review, add, promote, walkthrough, and fix. I modeled it after the built-in /review command and extended it meaningfully. You can clear context between review stages because state is stored in JSON artifacts on disk, with built-in scripts for keeping it updated.

It's my JavaScript runtime, built from scratch over many hours of work. Much effort has gone into keeping the binary size small, around 9MB at the moment (6.5 MB with -Os). On my M4 Pro, the hono coldstart bench (examples/npm/hono/bench-coldstart.js) lands around 5ms, about 2.4x faster than bun, and 5.8x faster than node. To keep things small, the engine ("Ant Silver") is hand-written, not a wrapper around V8/JSC/SpiderMonkey. The JIT is still a work in progress but it uses a fork of MIR as the backend. Ant currently targets the WinterTC Minimum Common API, while also passing 100% the javascript-zoo compat-table tests, and is sitting around 64% on test262. Why did I build Ant? Well, I wanted a runtime small enough to ship with CLI's and small Docker containers without having to drag along 50 to 100mb of just runtime....

Show HN: Armorer – A secure local control plane for AI agents Hey HN, I built Armorer because I was tired of two things: 1. The absolute "dependency hell" of setting up new AI agents (Codex, OpenClaw, etc.). 2. The security risk of giving powerful local agents broad access to my host machine. Armorer is a secure local control plane that manages the lifecycle of your agents. It uses Docker for true process isolation and provides a unified UI/CLI for monitoring and job tracking. One feature I’m particularly excited about: you can point an existing coding agent at the Armorer repo, and it will autonomously install and configure the entire stack for you securely. Source: https://ift.tt/5QDGHW4 Website: https://armorerlabs.com I’d love to hear your thoughts on the architecture and how you're handling agent security locally. May 8, 2026 at 01:38AM

Show HN: Gpu.fund, live GPU cloud rental prices I built gpu.fund as a small live price board for GPU rentals. It tracks cloud inventory and hourly prices across providers so you can quickly sanity check what H100s, 4090s, 3090s, and smaller cards cost right now. Mostly made it because I got tired of opening six tabs just to answer one question: what is the cheapest usable GPU today? Feedback welcome, especially from people renting GPUs for training, inference, or weird weekend experiments. https://gpu.fund/ May 7, 2026 at 12:31AM

Show HN: Dreamwork – a job search site I made after Indeed fired my pregnant wif Hey, I’m Colin and I have a fun story for you. My 7 month pregnant wife was laid off from Indeed (she was a PM there) back in December. This pissed me off quite a bit, as she was supposed to get 6 months leave and instead got fired. So I spent the last five months working part time to build Dreamwork, a platform aiming to make the job search experience actually better with AI (not just mass application spam). I started with just a telegram bot doing scraping, then advanced to Google Embeddings 2.0 for vectorizing the jobs, built out a tight 6 axis scorecard for both the user and each job. Then I actually got to use my English degree (lol) to optimize the prompt for custom per-job resumes and cover letters to make them not sound like - again - shitty AI. Most AI cover letters have a kind of consistently dead quality. They use all the keywords and somehow communicate nothing. I absolutely hate that, so I’ve ...

Show HN: I indexed 8,643 BSides talks across 227 chapters and 6 continents Hi HN, I'm Roland, and for the past few weeks, I've been building AllBSides — a directory of every BSides conference talk uploaded to YouTube. As of today, 8,643 talks from 5,927 speakers across 227 chapters in 68 countries. Combined runtime is 280 days. The transcripts come to about 60 million words. The archive came together in stages: 1. Manually map every BSides chapter's YouTube channel 2. Pull every video and transcript from Supabase 3. Run each transcript through Haiku for tag extraction (tools, topics, difficulty, team, talk style, research method, and much more) 4. Run results through Sonnet for categorization and dedup 5. Final pass goes through Opus for verification 6. Do a manual verification - at one time, the pipeline showed over 16k AI suggestions for manual verification. Today, most are resolved. Total LLM cost so far: about €200. The whole pipeline is rebuildable from scratch. Each t...

Show HN: Kula – a family health platform that makes sense of your data My parents are in India, I'm in the US. Their health system was continuous WhatsApp photos of lab reports, vague updates over the phone, and me finding out about doctor visits weeks later. So I built Kula. Upload lab reports (photo, PDF, WhatsApp forward) and it have them parsed and track trends. Connect a wearable and track daily health signals as well as your baselines. Everything goes into one record you can search and review over time. There's a chat layer where you can ask questions in plain language like, "what's my dad's cholesterol trend showing", and get a sourced answer from your own data. Primarily built it for my family. My parents told me they'd use it even without me, just to have their records organized before doctor visits. That truly changed how I think about it. Looking for feedback on this platform. Would you use this? What are your thoughts? What's missing? www....

Show HN: Enoch – Control Plane for Autonomous AI Research I built Enoch after working with OpenClaw and trying to get an agentic coding system setup with Codex. In the past, I was trying to manually generate, code, and test this all manually. Then - I figured I'd try to start automation. Too many times have I typed "Continue" and gone back to my work. I figured I could automate that. Well - Enoch is what stemmed from that. My first implementations were a mess with OpenClaw. I'll spare you the details. I moved to n8n. n8n was not bad but it felt like I had to strong arm it to do what I wanted. Had issues, but less. Then this system - LangGraph / FastAPI... it has been working pretty well. The papers generated seem to have meaning. Generation of ideas have shown to have some positive substance. All ideas are grounded on a basis of pass / fail or positive / negative - based on criteria set on idea generation. I will spare you too much reading. Disclaimer: Yes, I used Cod...
