Show HN: A little physical breakout clone https://ift.tt/taeBLXu

Show HN: A little physical breakout clone Idea: How about a 5 minute game I can play in my browser and it's actually fun to play. Controls: Mouse or keyboard (left/right, left alt/right alt or A/D), space and esc are pause toggle. Page up / Page Down are next or previous level (if already unlocked). Cheats: Z toggles zapper, M toggles magnets. Debug stuff: I, P, E keys are toggles for various stuff (E lets you change some aspects of physics engine). Game is maybe playable on mobile devices, there is a menu on top right, and then click the circle to select type of control. Physical engine is decoupled from refresh rate and runs at 240 Hz. Fully vibe coded (deepseek, chatgpt), levels are human made with some amount of love. https://brontosaurusrex.github.io/physical/v7/ July 31, 2026 at 08:13PM

Show HN: Supapool – a Supabase per coding agent in ~400 ms https://ift.tt/RE1SMel

Show HN: Supapool – a Supabase per coding agent in ~400 ms hi HN, I built supapool.io, an ephemeral full copy of supabase's services that you can spin up in ~400 ms (Auth, postgres, storage, realtime). so if you run multiple coding agents in parallel in different worktrees, they can now have their own copy of supabase without making changes that conflict with eachother. > why not use supabase docker locally? when I run 3-4 instances locally, my macbook gets hot and sometimes freezes. > why not use supabase branches? branches take minutes to setup, and are designed for persistence. this is expensive, and for a dev environment, it is too slow. > why not use mocks? mocks are bad for agents. i expect agents to test their migrations, SQL against real prod service behavior. agents hallucinate working mocks often. However, upside of mocks is that its faster and runs locally, but with supapool, the upside is less convincing. > how does it work/how is this economically viable? s...

Show HN: Hacker Fables – A satirical cyberpunk novel you can read as a man page https://ift.tt/N0C9iT3

Show HN: Hacker Fables – A satirical cyberpunk novel you can read as a man page The project is entirely open source. It takes a single Pandoc Markdown source file and produces HTML, EPUB, PDF, man pages, GNU Info, an audiobook, an HTML-integrated audio player that highlights the content as it plays, and an MP4 output for the "video audiobook." It's generic enough to be reusable. I plan to use the pipeline for my tech blog later on. The novella contains a lot of programming lore. It's an over-the-top love letter to the old-school Linux programmer and to the craft itself.

Show HN: CheapFoodMap – A map of good meals under $10 https://ift.tt/VyXTpiY

Show HN: CheapFoodMap – A map of good meals under $10 I was recently laid off after 18 years, and gave myself 100 days to build soething useful in public. CheapFoodMap is a crowdsourced map of meal under $10, excluding franchises, local good eats only. It's inspried by 거지맵 (Begger's Map) a Korean crowdsourced map students use to find cheap eats. Ocverage is heaviest in Texas, since I live in Dallas, but have 1200 meals across 15 US cities. Seed data came from Google Review, 4.2 star or higher with at least 500 reviews, and verified price under $10 per menu item. Things I would love feedback on : whether the price-freshness model makes sense, and what would make you trust the price on a site like this. How to encourage people to update prices, since inflation is making food price very frequent. https://ift.tt/cEpNOml Any and all suggestion will be super helpful. Thank you! https://ift.tt/Wyld8nv July 29, 2026 at 10:29PM

Show HN: Writekin – fine-tune a local LLM on your own writing, on your Mac https://ift.tt/olQV9Ct

Show HN: Writekin – fine-tune a local LLM on your own writing, on your Mac Hey Hacker News! I built Writekin over the past week because I was tired of AI writing that didn't sound like me, even though I had just used AI to clean it up, rather than wholesale write it. The usual fixes I found online for this were: - Some sort of SKILL.md, or - A system prompt full of rules to strip the generic AI tells (e.g. no em-dashes, none of the stock phrases, varying the sentence length, etc). While those cleaned up the surface a bit, Pangram still came back as ~100% AI written, which was frustrating, as again it was mainly taking my sloppy copy and tweaking it. So when building Writekin I took a different route: Writekin fine-tunes a local model on your own writing. It reads what you've already written (Apple Mail, iMessage, local documents, chat exports), curates it into a training corpus, and runs a QLoRA fine-tuning on-device via Apple's MLX. A Compose screen then drafts and rewrite...

Show HN: Let's Seal – Let's Encrypt for document signing, free and self-hosted https://ift.tt/T0pexzX

Show HN: Let's Seal – Let's Encrypt for document signing, free and self-hosted TLDR, Let's Seal gives the finger to Adobe and every doc signing tool (docusign, google, etc) who pay to play with the Adobe Approved Trust List and then charge you for something that should be free. Currently even the person checking if a document/contract is sealed or code is authentic has to also be inside the same Adobe walled garden too. Verification, the part that should be free is the part everyone charges for. Thats the shape Let's Encrypt fixed for TLS, and I wanted the same thing for documents and files. The core idea therefore needed to go a bit beyond e signatures and i created an open standard (SEAL), plus free tools that implement it. When you seal a file, three independent things happen. 1. it gets a signature from a certificate authority, chaining to a public root. 2. its record is appended to an RFC 6962 transparency log. and 3. its SHA256 is timestamped on a public blockch...

Show HN: Working Async – The new wave of remote work is async-first https://ift.tt/sPh2Gc1

Show HN: Working Async – The new wave of remote work is async-first After living in multiple countries around the world and working remotely, I discovered that the best working cultures are asynchronous ones. An asynchronous working culture is a model where team members collaborate and complete tasks on their own schedules, without needing to be online at the same time or respond instantly. This means employees can work when and where they please for maximum productivity, often times companies who have succesfully implemented async communication have teams with employees across the globe. I created a job board dedicated to curating these types of jobs because I strongly believe that async communication will be a standard for many job types in the future. You can check out the site here: https://workingasync.io Right now there are over 400 jobs listed (including roles from companies like DuckDuckGo, GitLab, and Docker). I’m planning to add new features over the coming weeks, and have ...

Show HN: I made some transistor animations https://ift.tt/gMLNVYA

Show HN: I made some transistor animations Hi HN, I made some animations of the most important kinds of transistors using my semiconductor simulation, details of which are on the page. I tried to make the visuals as realistic as possible while also aiming for clarity. If you want to go beyond the charge carriers and look at, for example, the electric field, you can do so in the simulation software. The desktop software also has less common devices like IBGTs and SCRs that have similar animations. The last thread about my software was posted here about a year ago: https://ift.tt/jdDVM1N https://ift.tt/sQiVecx July 25, 2026 at 12:07AM

Show HN: Trifle – Open-source analytics that stores answers, not events https://ift.tt/X0PevKI

Show HN: Trifle – Open-source analytics that stores answers, not events Trifle is an open-source time-series analytics library that aggregates nested counters instead of storing raw events. All in the database you already have. After rebuilding it twice over 10 years, it now tracks ~1B events a day at my day job. It started in 2015 as my own Rails APM. I plugged into ActiveSupport::Notifications, got a few small users, and one bigger one whose scraping app broke everything. That sparked the core idea: aggregate counters into pre-defined time buckets, so a single write increments multiple buckets at once. The APM eventually faded away without much traction. Later in 2021 I needed analytics at my day job. Instead of going for something out there I revised the idea of Trifle as a more generic analytics library, borrowing some data warehouse ideas. First used Redis, then Postgres, eventually MongoDB. Hence why Trifle::Stats comes with multiple drivers that keep the DSL unified while storag...

Show HN: Setoku – Self-hosted knowledge server for AI agents https://ift.tt/DarK28B

Show HN: Setoku – Self-hosted knowledge server for AI agents hey hn, I wanted to share a side project we’ve been using and iterating at Hedgy for the past couple weeks. It’s our take on a self-hosted company brain that is powered entirely by our claude subscriptions. It includes a ClickHouse data lake for ingesting data and light knowledge infrastructure for storing knowledge about the data (e.g. this is how we count a user as active, check column X when determining LTV). This is exposed to our AI’s via MCP. No inference happens in setoku itself, it’s just a data tool you give your agent. The MCP encourages the AI to record gotchas and insights as it finds them and there’s a minimal admin interface for auditing and pruning knowledge [0]. I had been pretty impressed with claude code’s data analysis abilities on my local postgres, so I was excited to ship this capability to my non-technical teammates to use from claude.ai and cowork. They thought of way more things to do with it than I d...

Show HN: Millwright – Rust-based, self-hosted LLM router https://ift.tt/Ugzr4Cd

Show HN: Millwright – Rust-based, self-hosted LLM router Hey HN, With the news of OpenRouter possibly being acquired and proliferation of hosted LLM routers (i.e. Ramp Router, Vercel’s AI Gateway), I saw the need for a self hosted solution focused on cost savings, transparency, and performance. So, I built an open sourced router with a simple CLI interface that can easily sit between coding agents and GenAI workloads. For the curious and lazy, at the moment, Millwright has the tools for, - Providers: OpenAI-compatible APIs, Anthropic, Amazon Bedrock - Routing: policy-controlled model roles (cheap, mid, frontier), cheapest healthy route selection - Protocols: OpenAI Chat Completions, Anthropic Messages, text and tool translation - Cache Affinity: role-scoped session lanes without serializing concurrent agent traffic - Spend Tracking: per-team costs, cache usage, model/provider mix, request traces - Cost Analysis: measured usage and modeled candidate economics (HTML, Markdown, JSON) - Re...

Show HN: CodeAlmanac – Karpathy-style codebase wiki from your conversations Hey HN! This is Divit from Almanac (YC S26). We built CodeAlmanac, a wiki for your coding agents that updates as you talk to them. It is open-source, local, and free. Here’s a demo: https://www.youtube.com/watch?v=XNQWV3TFBWM Your CC/Codex conversations contain a LOT of knowledge that is forgotten because it was never documented. People have their own methods of documenting their chats. We used to make Markdown files like MANUAL.md and DESIGN.md, and would prompt Claude to keep them updated. The problem is that these files quickly become outdated and messy, and there’s only so much you can put in a single file. So we set out to build CodeAlmanac. We wanted something that was 1) maintained automatically, 2) lived inside our repository, and 3) used our existing Codex/Claude Code subscriptions. CodeAlmanac maintains an almanac/ folder inside your repository. It contains connected Markdown pages that cover things...

Show HN: Roll Solver – daily multiplayer word puzzle PWA https://ift.tt/VMsgAIq

Show HN: Roll Solver – daily multiplayer word puzzle PWA So I started this project because my wife wanted a way to check if her word dice game rolls were solvable to avoid wasting time on a roll. I started a building a tool that accepts a picture of the dice and quickly answers if the roll can be solved. Well, that quickly devolved into building a highly-optimized solver efficient enough to run in the browser on WebGPU. Once the solver worked, it turned into an excuse to finally explore multiplayer game dev, which I did with PartyKit and some Cloudflare primitives (durable objects, D1, workers). During this process it all became an actual game I shipped. Where the games features ended up: - A "daily" mode where everyone gets the same 12 tiles each day, and the scoring goal randomly changes (most words, longest word, most crossings, rarest words) tracking streaks and leaderboards. - Real-time multiplayer - 1v1, or drop an invite link into a group chat and up to 10 people race ...

Show HN: Lific: Issue trackers should be simple, right? https://ift.tt/O27WkwZ

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 eventually removed it and went back to .md files for a few weeks. Lific is the opposite shape of most of your self hosted server issue trackers: It's a single Rust binary that uses SQLite, and it has an optimized MCP server built in. Web UI is also included integrated directly into the binary. The simplicity is meant to only apply to the size and the ease of installation. The web UI is fully fleshed out with all of the UX you would expect fr...

Show HN: Leet Robotics: Learn robotics and ROS2 with hands-on courses Hi all, I've just launched Leet Robotics: a platform to learn robotics hands-on, with a full ROS2 workspace that runs in the browser (Jazzy, Gazebo Harmonic, Foxglove, VS Code) - no install required. The platform also has room for sharing projects and simulation assets as it grows. Our first course is live now: Intro to ROS2 (free to read). The course teaches skills ranging from building your first node to a capstone project of a robot touring a museum world, with every lesson runnable in the online workspace (free accounts get an hour of workspace time daily - enough to follow the course). Would love feedback from this community: on the course, the workspace experience, and what courses to build next. https://ift.tt/P43qx6m July 15, 2026 at 05:44PM

Show HN: Make senders work to get into your inbox https://ift.tt/6j9doyl

Show HN: Make senders work to get into your inbox Hi HN :) really excited to share this with you. The one thing AI reliably does is generate noise. Half the tools I see launch are just machines for producing more noise across more channels. And people are starting to see this in the form of emails in their inboxes as spam filters are struggling. There used to be a useful signal in email: the effort a sender put into customizing a message was a rough proxy for how relevant it actually was. AI killed that. Now it's customized slop with the appearance of effort with none of the cost. It is painful that the open internet / open channels have been abused like this. Captchainbox applies the idea of proof-of-work to email. If a sender is willing to do a bit of work to reach you, the message is more likely to be worth your time and the sender more likely to be real. The work is a traditional captcha. You can also set a pay-to-deliver amount if you want more friction. The proceeds of the de...

Show HN: Pgnudge - tell your app which Postgres tables just changed Genuinely unsure if this is crazy or cool: looking for feedback. pgnudge is a small async Python library that tells you which tables just changed in Postgres, so a cache or read model can refetch the moment the data moves. No row data - it tells you when and what to reload, you already know how to load it. It leaves nothing persistent on the server (temp replication slot, dropped when the session ends) and needs no database driver — it speaks the walsender protocol itself. One dependency. Not CDC (no before/after rows), not a queue (no durability). It moves wakefulness, not rows or work. Repo: https://ift.tt/D7BqiLA https://ift.tt/D7BqiLA July 12, 2026 at 11:27PM

Show HN: SubjectiveZero, an open-source agentic node editor for creative coding https://ift.tt/AfM3rg8

Show HN: SubjectiveZero, an open-source agentic node editor for creative coding Hey there, My name is Clem, I've been a solo indie dev for a couple years now, exploring frontier tech like XR and agentic workflows in the context of creative / interactive work. I've been building creation tools for a while and some common design challenge is to figure out the right level of abstraction for your tool. You can always make it super advanced and complex with low level concepts (shader composition, actual code etc.) but then you get something with a high complexity / learning curve. On the other hand, if you make your tool too high level, it might be easier to use at first, but people will most likely hit a wall eventually and start fighting with your tool to get their edge case done (you see that on mobile a lot actually). With this prototype (called SubjectiveZero), I'd like to imagine that we can kind of move the "slider" on the abstraction layer, meaning that you can...

Show HN: Wyrm – Solve algebra by touch, built on an open-source soundness engine https://ift.tt/AQiwJh9

Show HN: Wyrm – Solve algebra by touch, built on an open-source soundness engine There is a mobile game called DragonBox. It sort of tricks you into learning algebra by starting with very abstract manipulations of a puzzle that must follow rules... gradually the game teaches you more and more rules and also strips out the more abstract elements until on the last levels you are finally solving real equations. I loved it, it taught my kids algebra.... and it was just fun. Over the years I often thought that there should be a calculator for Algebra that works this way... something where you can drag terms around and cancel & distribute with gestures, but most importantly enter your own problems. It should also do more kinds of problems than DragonBox allowed. So I finally decided to build it. https://dicroce.github.io/wyrm/home.html Here's a video showing it: https://www.youtube.com/watch?v=_STbS4zvIlU .

Show HN: Real-time n-body tree code in CUDA https://ift.tt/9X3mwYd

Show HN: Real-time n-body tree code in CUDA Sharing an old project of mine, on my RTX 500 Ada laptop GPU, it can simulate up to 4 million particles at ~400 ms per step using the Barnes-Hut algorithm, saturating the 4GB of VRAM available. The octree construction is fast, as well as the traversal. The major bottlenecks are the VRAM usage (1 million bodies require ~1GB), which could be probably halved by reusing intermediate buffers, and the particle to leaf evaluation, which would benefit from more fp32 FLOPS. Moreover, I still don't have a good heuristic to predetermine the size of the BFS queue, perhaps some sort of memory paging could solve the issue. https://ift.tt/T4w6FQp July 10, 2026 at 09:17PM

Show HN: Halo – open-source, tamper-evident runtime evidence for AI agents https://ift.tt/PUpnOMw

Show HN: Halo – open-source, tamper-evident runtime evidence for AI agents Hi HN, I'm Brian, I spent the last few years at Vanta (YC W18), helping startups and enterprises become compliant and I recently started exploring what that might look like in a post-agentic world. The problem Halo solves is: when a company buys an AI agent from a vendor and gives it access to their data, they have no way to check what the agent did with that data. Vendors may have built observability dashboards and audit logs, but those are editable and partisan. SOC 2 and ISO 27001 audit a company's controls, but controls are less predictive when the software is agentic. TLDR: give an agent the same prompt 50 times, and you get 50 slightly different actions/answers - so the only thing worth auditing in a post-agentic world is what happened at runtime. Halo is an open-source project that produces agent runtime evidence. It's a small recorder that records every action an agent takes (eg. tool calls, ...

Show HN: Record, replay, and improve AI agents in production At the AI Engineering World's Fair a big part of the conversation was to nail the self improvement loop. Our take on this is to record state of the agent execution with a durable runtime, then allow users to replay from state checkpoints and run 'what-if' experiments. It's OSS and free to use. Would love some feedback from the community. https://ift.tt/a0pTgNS July 6, 2026 at 10:56PM

Show HN: I built an encrypted BLE dongle for pasting stuff to air-gapped devices https://ift.tt/ewLDBOu

Show HN: I built an encrypted BLE dongle for pasting stuff to air-gapped devices Definitely one of those "20 minute adventure gone wrong" projects where all I wanted initially was a quick wireless rubber ducky for bitlocker keys and the like and then I kept adding stuff like AES-256..... Currently working on adding WebAuthn/FIDO support because the hardware is already there and scope creep is a lifestyle at this point. Would love feedback, especially on the security side. Repo and PCB files are fully open source. https://ift.tt/tKUTes1 July 5, 2026 at 02:43AM

Show HN: Typocalypse – An Arcade Typing Roguelike I created a small typing game. Would love to get some feedback on it. What can I improve? Are there any features you're missing? Are you having fun playing it? I certainly did have fun :) https://ift.tt/nueaNT2 July 5, 2026 at 12:58AM

Show HN: AnythingLLM Fork as NPM Package https://ift.tt/QYyWU3N

Show HN: AnythingLLM Fork as NPM Package I am a huge fan of anythingLLM, I’ve used it extensively. I had use cases that it doesn’t quite fit; so I decided to fork it as an easy to install, lighter weight package. I’ve been changing the agent mode code to focus more an automation. I’d love your feedback! https://ift.tt/a9wNTxC July 3, 2026 at 01:25AM

Show HN: Bramble – Local-first password manager https://ift.tt/sqWHPYk

Show HN: Bramble – Local-first password manager I'm currently working on Bramble, an open source password manager with P2P cross-device sync. Initially I released the Chrome extension, but recently I also published the Android app and iOS is pending Apple's approval. Besides that, the latest version also includes passkey storage for all platforms! About Bramble: It aims to be as feature-rich as all popular and a replacement for cloud-based providers. I don't think we need to store our data in the cloud and be at the whims of companies raising their prices every year. There's always a breach and then we find out that some fields aren't encrypted, metadata is visible, and so on. I'm frustrated with this and the increasing lack of transparency during these breaches. The P2P sync in Bramble uses a Nostr relay (which can be self-hosted) to keep your devices in sync. The relay just introduces the devices to each other; the data then flows directly over WebRTC, so ther...

Show HN: Bais.News – News Neutralization Piepline Solo dev here, been working on this project the last 7 months and I need some feedback. Bais aggregates news stories from a broad range of sources and synthesizes an article focused on reporting the overlapping coverage of all sources. The goal being to provide a fact first account while eliminating narrative spin and emotionally charged language. Happy for any feedback, thanks. https://bais.news July 2, 2026 at 10:59PM

Show HN: QR code renderer in a TrueType font https://ift.tt/KMrbXIG

Show HN: QR code renderer in a TrueType font In the "Libre Barcode Project" discussion yesterday, 1bpp asked: "Is anyone willing to sacrifice their sanity for the sake of implementing a QR renderer as TTF hinting code?" Yes. I had some tokens to burn and was curious... turns out, it's possible. This was put together by a mix of Gemini, GPT, and Claude (depending on which usage limits kept running out). https://qr.jim.sh/ June 28, 2026 at 06:07AM
