Git Submodules as a Package Manager

https://nesbitt.io/images/boxes.png
I added a worktree to a repository last week to try a branch alongside the main checkout, ran git submodule update --init in it because the build needed the vendored dependencies, and when I was done went to clean up with git worktree remove, which git refused. Per the man page only clean worktrees can be removed, and “unclean worktrees or ones with submodules” need --force. Submodules get ...

The process involves installing Tor and its arm, configuring port forwarding on a router, and serving an "about this node" page over HTTP to provide information about the exit node's activity.

“Next-token predictor” is the wrong mental model for LLMs

Large language models are next-token predictors, but this is an incomplete description as they also learn from new sequences generated through exploration. They predict the next token based on existing data and rewards during post-training techniques like reinforcement learning with verifiable rewards.
