Codemaxxed – 350M+ LOC and a GitHub cease and desist
Built this code art project as a commentary on the recent wave of using LOC as a primary measure of engineering productivity It's now up to 350M lines of useless (but hopefully funny) code, constantly growing using GitHub actions and https://github.com/jshchnz/codemaxxing Unfortunately, GitHub has now sent me a notice to remove the repo within the next 14 days, so enjoy it while you can

I hit my Claude Code usage limit yesterday in the middle of regular work. Not doing anything unusual - just a couple of coding sessions. It felt like it came out of nowhere. Then today Anthropic announced they're tightening 5-hour limits during peak hours. It feels like a rug pull is coming and we're all just supposed to accept "you've used too much" with no explanation of what "too much" means. Usage limits have always been opaque.

- IBI built a 500K LOC production app alone in 7 months. Here is the proofMay 2026 · ▲5

I believe I am the first human to have done this in a documented, verifiable way: maintaining a stable production-grade 500,000-line TypeScript codebase as a solo developer, using an AI coding assistant I built myself. If you know someone who has done the same, one person, 500k lines, documented proof, please write their name in the comments.

My weekly(ish) video logs tracking my progress of building a completely sound statically typed language and structural editor. The motivation is to make lots of invalid programs unrepresentable.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
