Show HN: Monochess – A chess variant with rule-bending action cardshttps://monochess.pages.devHey HN,A while back I saw a video[0] of people playing chess but using action cards to modify the rules mid-game (skip turns, reverse, draw 2, etc.). It looked incredibly chaotic and really fun to play, so I decided to actually build it as a playable online game. A small difference in Monochess is there's no need to call out a phrase if you just have one piece. I noticed while testing with the mrs. it became really annoying to keep doing this every move.That also gave me a really good reason to build on Cloudflare using their entire stack, something I've been meaning to get my hands dirty with for quite some time. The app is built using SvelteKit and hosted on Pages, there's a Durable Object worker-backed game server, and D1 as the database layer for accounts/games.This project included:- A Custom Engine: Standard chess engines panic when forced into illegal board states. The engine wraps standard chess logic to allow for mid-turn state changes—handling concepts like rolling back a comMay 28, 2026 1:58 PM

Show HN: Monkdev is a toolkit and methodology for coding with LLMshttps://github.com/oeo/monkdevI'm sure many people have some solutions similar to this but I've been using some variation of this since roughly the release of Opus 3 to get higher quality results. Like, significantly higher. So I decided to make it into a more structured package.Problem: bad decisions and short sighted solutions due to the LLM not having enough context before acting. They'd read one file, or a few segments of a set of files using a super conservative offset and limit, guess about the rest, apply a patch, run a unit test and then tell you with its entire chest that the code is production-ready.Those bandaids over time became debt, drift, complexity. Unnecessary LOC in a codebase where I find myself wondering is this thing even making me more efficient or should I be in VIM more often and just save myself the API costs (I use OpenCode + OpenRouter and have been known to blast through hundreds of dollars a day in spend using Frontier models).I found that, for whatever reason, LLMs respond to role-playMay 26, 2026 7:08 PM

Is it too soon to built software factories?https://news.ycombinator.com/item?id=48268815I keep hearing about “software factories” / background coding agents that can autonomously work on production repos.

Show HN: Objo Studiohttps://objo.devObjo Studio is a new development environment for building desktop and command line apps. It has a visual designer, a debugger, a compiler, and a modern BASIC-like language called ObjoBasic. The aim is simple: make it enjoyable to build real applications for macOS, Windows and Linux and learn how to program.I've been working on Objo Studio in one shape or another since about 2019. I've always loved tools that let you move quickly from idea to working prototype and that abstract a lot of complexity and get out of your way. This has been tried before (VisualBasic, Xojo, etc) but have either been abandoned, become expensive or lost focus on hobbyists.The whole stack is written in C#. There's a custom stack-based VM that is roughly on-par with Python for speed but this is not a high performance tool. It's an all-in-one IDE for visually developing cross-platform desktop apps. It tries to make it simple for users, abstracting runtimes and libraries to help newcomers learn but also let them thMay 11, 2026 3:38 PM

There is not a strong open-source drawing engine beyond toy demos. Thus, mobile-ink aims to solve this problem and provide a state-of-the-art mobile note-taking canvas package.mobile-ink uses native Skia/Metal to address issues with native rendering, pencil latency, eraser behavior, page virtualization, preview caching, memory stability, page interactivity, etc. It has many advanced features such as shape-snapping, primitives to integrate figures, custom backgrounds, pdf import, stroke selection, smooth zoom/scroll, and more.The package is iOS + React Native as of now.May 8, 2026 5:01 PM

Show HN: An Agent First Slack CLIhttps://github.com/tilework-tech/nori-slack-cliHey folks,My team and I have been building a background agents as a service product. One of the things we needed pretty early on was for some way for the agents to be able to drive slack.Right now, I don't think there are many good agent-first ways of doing this. I don't love MCP -- it's just too many tokens in the context window, and agents seem to do better with CLIs because they can embed them in code and so on. But other CLIs that exist are either a) subsets of the web api that only focus on human needs and b) have polished terminal UIs with spinners and colors and interactive things that make it hard for LLMs to actually use them.nori-slack-cli is a very thin dynamic wrapper over @slack/web-api (i.e. bolt). Whatever the SDK can call, the CLI can call. When slack adds a new method it should just work without a new release on our end. (Inspired by the GWS cli: https://github.com/googleworkspace/cli).So you(r agent) can do things like:`nori-slack chat.postMessage --channel C123 --texMay 1, 2026 7:05 PM

Ask HN: Macbook or Linux Laptop for devs and heavy users?https://news.ycombinator.com/item?id=47974702Hey everyone, I'm really curious to hear from people who pushes high end MacBooks and Linux laptops to their limits in daily use. I'll share my daily experience with my Linux laptop below, and I'm hoping to use the feedback from those who have been on both sides to decide if I should make the jump to a MacBook in the future. My experience: I'm a web developer doing both frontend and backend. I also do some mobile dev with Flutter. Personally, I prefer using an Android phone and a Linux machine. I'm currently using an Acer laptop with an i7-13700H and 32GB of DDR4 RAM. I got my company to buy it for way cheaper than similar models on the market. While the overall performance is really good for the price, the speakers are absolute trash and the screen is just okay. Here is what's on my mind: Even though I can get about 3-4 hours of coding done on battery, it's obviously nowhere near a MacBook. I don't really need that long battery life most of the time, but it still sounds nice to have. May 1, 2026 1:40 PM

This encourages care and consideration. - Nobody knows who you follow or what posts you react to, besides you and the other user. These stats are personal, so people view your logs free of outside influence. - Posts are rich text-only, no images or videos, in an effort to reduce mental clutter. - Your feed only features users you follow, to give you increased control of what you see, unless you click the "global" checkbox to see all posts.quick demo: https://www.youtube.com/watch?v=7CTnORsGnL8 overview page: https://www.weekly-log.com/about/overview---I have soft-launched this website, and a handful of my friends have signed up aApr 21, 2026 2:02 AM

Getting back into photography, ditching the phone camera in 2026?https://news.ycombinator.com/item?id=47842292I've been looking through twenty-five-odd years of my own photos. The collection includes scanned 35mm and medium format images; digital pictures from a few Canon Powershot generations and a 20D SLR; and about five iPhones.I've noticed that the non-cell-phone pictures tended to be better, and that in general I seemed to have quite a bit more fun with photos taken with, well, "real" cameras. Probably the best ones were taken with the 20D, which for its time was a really nice camera, for which I was able to bring over some lenses from my film days.I wouldn't rule out more film photography but I think of that as a somewhat separate track. I'd like to get a digital camera that captures a bit more of what I enjoyed about film photography - that high image density, looking through a physical viewfinder, not necessarily curating images in real time... looking, shooting, and moving on.I've been following Fujifilm cameras for awhile in this market, having read about them here a few years ago.
