New top story on Hacker News: Show HN: Reladraw – A diagram language where you decide where to place things
Show HN: Reladraw – A diagram language where you decide where to place things
17 by jpwalsh234 | 0 comments on Hacker News.
I love making diagrams to help understand, plan, etc. However, the options are (A) auto-placement languages like Mermaid or Graphviz (which don't let me decide how the diagram looks), or (B) software like Draw.io which are powerful but are very time consuming (and inefficient for agents to manipulate). I wanted to have the benefits of both, where you can define a diagram in a diagram language, but also retain a high degree of control over what the diagram looks like. I also wanted this to work well for humans and agents. On the Github link, there's a playground where you can try it out without installation. There's also instructions for a simple npm install and for installing a skill you can use with Claude or other agents.

New top story on Hacker News: Show HN: Ax-check.com – Can agents use your product?
Show HN: Ax-check.com – Can agents use your product?

I'm the co-founder of Gauge, and I built ax-check.com to quickly test how well coding agents can onboard to your product. You'll get a scorecard, specific suggested fixes, and three full coding sessions that show how agents read your site and use your product. I built this because similar checks were too noisy. Most suggested obscure technical changes that don't actually make a difference in agent experience (or AX, hence ax-check.com). This check starts by using DeepSeek 4.1 Flash to try to find key information about your product, starting from the homepage. In actual agent traffic data, we've seen that the key pages are the homepage, llms.txt, pricing, and the docs site (by traffic volume, and by influence), so we focus on those and ignore the rest. We also find that content negotiation for Markdown is legitimately helpful for agents to complete tasks faster and find what they're looking for, so the scan tests that your key pages can serve Markdown. The other key piece is that we run actual coding agents in sandboxes, and have them try to onboard to your product. You can see the full trace and watch it happen live (we kick it off fresh when you enter a new site). We surface interesting findings like hallucinated URLs, inaccurate docs instructions, or product confusion. It also detects whether the agents could complete a fully working onboarding autonomously, without being blocked by a login wall. This is still controversial, but I think finding ways to let agents safely onboard autonomously is going to be table stakes within a year for developer tools in particular. The whole site is agent-friendly itself! You can generally just talk to your coding agent about ax-check.com and it can do the rest. Would really appreciate any feedback to make this useful.

New top story on Hacker News: Show HN: DOOM in the kernel, or fibers in eBPF
Show HN: DOOM in the kernel, or fibers in eBPF
11 by ayles | 3 comments on Hacker News.
Some time ago my coworker who was working on first version of Perforator ( https://ift.tt/sfpIVPG ) kept talking about eBPF, so I got curious about its ISA and restrictions. That was around the time I read about DOOM on pregnancy test, so I thought: "what if someone run DOOM inside of Linux kernel in eBPF? Surely, with some restrictions, this should still be possible?" I started to play around with it somewhere in 2024 - first stripping DOOM to bare minimum that is needed for showcase, simplifying code and trying to pass first restrictions that I encountered - function limit, recursion, memory access and checks. I tried to do this by hand, but it was, well, tedious labor. So I changed direction and instead started to do some of the things with LLVM-passes - rewriting memory access, simplifying and rewriting loops etc. But there were just so many corners. And given absence of time and all, I forgot about this project. But couple months ago I thought: "LLMs are quite good nowadays, so why not try again this time with more hands". I tried different approaches on how memory access could be "virtualized", how loops can be made bounded, and in general - how to run unbounded logic on such a machine. When I got DOOM running, I got carried away. Approach was so "generic", so it would be a crime not to try to run more things. And now we have it - lua running on xdp hot path, llama2 working with softfloats, and even cpython, that did not fit initially into 1M verifier budget, is running there now thanks to freplace. There is ton of work to do in order to make programs run faster, to make integration easier, but working examples are already there.

Ask HN: UK Rescue Rocket Sheds/Houses Information
12 by burnt-resistor | 6 comments on Hacker News.
I can't seem to find pictures or significant details (nothing on Wikipedia) about the coastal buildings purportedly used to contain shipwreck rescue rocket apparatus. Many of the buildings still exist and are Grade II listed. Anyone have any additional anecdotal/local/oral tradition information that isn't found in the little blurbs online on the few websites mentioning them?

New top story on Hacker News: Porting my 1993 Amiga game to Godot, with an LLM reading the 68000 assembly
Porting my 1993 Amiga game to Godot, with an LLM reading the 68000 assembly
36 by rabahs | 6 comments on Hacker News.
These are my notes from porting my Amiga game, which I originally built in Baghdad in 1993 in MC68000 assembly, to Godot, using Claude Fable 5 during last July holiday. It took an evening! Getting the feel right and shipping it took a few more weekends and evenings. I spent the last few weeks analyzing what Claude did, feeding it my 33 years of memory of how I built the game, my notes and the git repos. It wrote the first draft of the article, and I edited line by line over a week. The screenshots of my 1993 map editor is the first I have run it since then. The one thing I never checked myself is the 108-byte explanation. Please post any questions. I am also releasing the original game for free.

New top story on Hacker News: Launch HN: Nori Robotics (YC S26) – A low-cost humanoid robot for development
Launch HN: Nori Robotics (YC S26) – A low-cost humanoid robot for development
34 by AntonioLi | 5 comments on Hacker News.
Hey HN, I’m Antonio from Nori Robotics ( https://ift.tt/TKasqr6 ). We build a $1,688 bimanual mobile robot in San Francisco for robotics developers and researchers. I started working on Nori while doing robotics research at Columbia. I was teaching robots through human demonstrations, but getting my hands on affordable hardware was difficult. Most labs have one or two expensive robots, which makes it hard to collect large datasets, run long experiments, or test across several robots. So I built my own. After seven iterations the latest Nori has: * 19 degrees of freedom * Two 7+1 DOF arms with a 1.5 kg payload per arm * A 55 kg telescoping lift * A differential wheeled base * Four 720p, 30 fps RGB cameras * 2D lidar * A dual microphone array with full-duplex voice communication * A 432 Wh battery * A Raspberry Pi 5 with 4 GB RAM (SLAM and safeties are run on board, heavier ACT and VLAs must be run from a computer via LAN or a server via WAN) Getting this under $2,000 was the main engineering challenge. Nori has more than 100 moving and structural parts, so costs add up quickly across actuators, bearings, wiring, power delivery, and assembly. Some main choices we made to get the cost low was using high-ratio servos instead of QDD motors, and using a wheel base instead of legs. We assemble each robot in San Francisco and have designed it to be easy to manufacture and repair (we offer 3D files to print repairs). Our open SDK includes teleoperation and demonstration tools: https://ift.tt/C7B0Ivh We also built a browser-based simulator so you can try it out: https://ift.tt/A4djy2C We’ve shipped our first robot and are building the next batch. Eventually, we want people without robotics experience to teach Nori tasks and share them with other owners. Currently the hardware is already capable of basic cleaning tasks, opening drawers, restocking shelves and pouring beers. Here is a video of Nori doing things: https://youtube.com/shorts/VRfVXHfQvD8 We make money by selling the hardware for $1,688, with optional paid software on top. Parts of hardware are open source. More details are in our hardware paper: https://ift.tt/zR8IbDc If you work in robotics, what would you build with a robot at this price? What would you change about the hardware?
