I'm working on porting KiCad to the browser. It's a lot of sweat and tears, multithreading issues and some more sweat. I've updated a port of WxWidgets and now I support all the features KiCad needs with ~200 tests. Right now I have a build that loads in the browser, but I really want to have "multithreading" which means workers in the web. One can use asyncify with emscripten to translate blocking C++ to WASM, but t…

#874Basically personalized meal planning and grocery integration. Since the Show HN I posted a couple months back I've been incorporating user feedback to add things like meal prepping, better ingredient reuse across meals, and cooking style preferences.
One of the biggest points of feedback has been adding more grocery stores but I'm really limited by who has APIs to actually integrate with, which is basically just Kroger and Instacart. Walmart has an API but ignored my API access request. Would love to hear if anyone has ideas on how to approach this.

#875SecurityBot.dev is an all-in-one uptime, performance, security, and SEO monitoring tool. I launched it a few months ago and have been iterating on it ever since. Later this week SecurityBot.dev will log its 1 millionth uptime check which is pretty cool to see.
It includes the usual uptime monitoring service that you see everywhere else, but also features such as a PageSpeed Insights monitor (https://securitybot.dev/pagespeed-insights) and a broken link checker (https://securitybot.dev/broken-link-checker). I continue adding new monitor types as I personally need them (and also based on use feedback).

#878I shared this last month, but I’m still having a lot of fun working on it. I made a daily word puzzle called Tiled Words. https://tiledwords.com Currently about 2,000 people play every day and I’ve released 59 puzzles! One feature I’m excited about is crowdsourcing puzzles. Today’s puzzle is a “community puzzle” made entirely from clues that players submitted! I plan to do this every week or two. I wrote about launch…

#880An AI coding tool desktop application written in Rust and Javascript. Cursor, Windsurf and etc uses too much memory on my machine. As an engineer it is important that the tools I use daily are performant and fast and I could use while watching a youtube video or browse hackernews.
While working on the tool I am building some boilerplates to start from, starting with mobile games targeting arcade games like Flappy Bird.
