Don't pay for an AI sandbox — build one locally with Docker

Don't pay for an AI sandbox. Build one locally that's secure with Docker.

Here's a practical guide that spins up a locked-down environment with a TUI, a persistent config volume, and a proxy to your local Ollama:

https://github.com/cheikh2shift/godex/tree/main#running-securely-with-docker

Why this setup?

Runs locally (no vendor lock-in)
Sandboxed tools (bash, filesystem, webscraper)
Config persisted in a Docker volume
Works from any project directory via WORKSPACE_DIR

Quick start

UID=$(id -u) GID=$(id -g) WORKSPACE_DIR="$PWD" docker compose -f $HOME/godex/docker-compose.yml up -d && docker attach godex && docker compose -f $HOME/godex/docker-compose.yml down

Ollama note
If you're using a host Ollama instance via the nginx proxy, make sure Ollama listens on 0.0.0.0:11434 (not just 127.0.0.1).

Go 1.23’s Iter package

A post about writing a custom iterator that returns a map’s values in a constant order.

Maps are notoriously known for changing their iteration order during each range loop. “When iterating over a map with a range loop, the iteration order is not specified and is not guaranteed to be the same from one iteration to the next.” The solution proposed by the Go team was to define a separate data structure that explicitly specifies the order of iteration; this may be a slice or array with the keys in the desired order.

In this post, we’ll look at a recent approach to solving the iteration order problem; as well as understand how to define a really basic iterator with the iter package.
