Show HN: Nixcage – Sandbox AI coding agents per project with Nix and direnv

Posted by hamidr on Friday March 13, 2026 @11:42AM
from the show-hn dept.

https://github.com/hamidr/nixcage

I built nixcage to solve a problem that's been bugging me: AI coding agents like Claude Code have broad access to your filesystem, network, and system. That's powerful but uncomfortable, especially on client projects or machines with sensitive data.nixcage creates per-project sandboxes that activate automatically when you cd into a directory (via direnv). It uses bubblewrap on Linux and...

Imagine a world where you are only allowed to work for cooperations such a this. Putting all the bureaucracy aside, to be filtered like this is such a Kafkaesque feeling.

Hmm, so you can hear noises? Doesn’t seem much of a capsule to me! How is ventilation done? Is that noisy too?

Re:Why is the Iranian government opening the world’s biggest bookstore? on Saturday July 09, 2016 @02:55PM (#12062752)
Disclaimer: from Iran

The fun thing about printed books in Iran(well im not sure about other states but at least about Tehran) is that you can almost find any censored book you want if you try, maybe just not in the bookstores, perhaps street.

Also the censorship in Islamic TV is just stupidly ridiculous but it's not that stupid comparing it to printed books.

Another fun thing about this topic is that I wouldnt have heard about this biggest(?! come on :|) bookstore if it werent for the folk who submitted this link.

Re:Introducing Verve: minimalistic, static, functional language on Friday July 08, 2016 @05:53PM (#12058896)
What do you mean by minimal? The syntax? I guess not since it's not that much minimal to other fp-langs such as clojure or even Rust.

Hmm I actually like the fact that the arguments of a function are defined using square brackets. It just reminds me of Clojure, especially the "defn" macro, which sounds pleasant to me.

I wonder what Lispers would say about that since I heard that not having a homoiconic syntax might cause some troubles at metaprogramming(macro) level.
