100% my experience with this service. The intent is good, but it seems they're still in the "fake it until you make it" stage.

Historically, I did it the other way around: have some autogenerated shell commands (dev, test, pull...etc) on my local machine that detect which language the project in the current folder is using, and calls commands accordingly. I did it this way because, in my case, it was challenging to consolidate multiple projects across multiple organizations under a single tool.

It's public, but I realize I haven't pushed my local updates for a while now. https://github.com/Betree/dev-commander

Show HN: Movement-based captcha – temporal reasoning to foil AI vision

betree — Thu, 12 Feb 2026 12:50:14 +0000

I built a proof-of-concept captcha that uses motion rather than distortion or object recognition. Solution characters move along a shared path with coordinated momentum; noise characters may follow shapes too but out of sync. You observe, identify the group by how it moves, type the code.

Rationale: static captchas are increasingly solved by vision models. Temporal reasoning over multiple frames is harder and more expensive for frame-by-frame AI analysis.

Client-side only, solution is visible in memory. Accessibility caveats apply (motion, vestibular, seizures).

Curious what the HN crowd thinks.

Title is misleading, Open Collective is not shutting down. See the other thread for more details: https://news.ycombinator.com/item?id=39540919.
