a few weeks ago I wanted to see if Opus 4.5 could build and improve upon a real open source library from scratch.

so I specced out globlin, a drop-in replacement for glob v13. up to 7.5x faster than glob, and up to 3.2x faster than fast-glob. all powered by Rust.

I defined the architecture, the API surface, every edge case I could think of: broken symlinks, extglobs, Windows drive letters, cyclic directories, permission errors.

kept asking Opus to poke holes until there were none.

then I let it cook.

158 commits. 21,000 lines of code. 1,451 tests across 53 files. cross-platform CI. all green.

it wrote fuzz tests. property-based tests. UNC path tests. macOS sandbox tests. more thorough than most human-written test suites I've seen.

npm install globlin, drop it in, done.

fully open source and MIT licensed under the Cap umbrella.

I don't know how to feel. this is insane. it works.

Hey everyone! Richie here, founder of Cap. After nearly a year of building Cap, we’re thrilled to unveil our latest relaunch.

Back in April, we introduced the first early version of Cap, and the response blew us away. We gained thousands of users, hit #1 on Hacker News (Show HN), and trended on GitHub with over 5k stars. Most importantly, we received incredible feedback that’s shaped the new direction we’re excited to share today.

The star of this release, v0.3.1, is our biggest feature yet: Cap Apps.

These are community-submitted apps that extend Cap’s functionality in exciting ways. The first app launching today is S3 Config, which lets you connect your own S3 bucket. With this, all new shareable links are stored and served directly from your bucket, giving you 100% ownership of your data.

One day!

thanks for this! agreed, will fix.

Definitely agree with what you're saying.

It's easier for us at the start to get some attention from Loom specific users by mentioning Loom directly, but it's not a sustainable strategy going forward.

Will update the marketing copy etc over the coming weeks/months to be more about the problem we're solving specifically.
