Git pre-commit hook for large files

This hook warns you before you accidentally commit large files to git. It's very hard to reverse such an accidental commit, so it's better to prevent it in advance.

Since you will likely want this script to run in all your git repos, a script is attached to add this hook to all git repos you create / clone in the future.

Of course, you can just download it directly to the hooks in an existing git repo.

If you find this script useful, you might enjoy our more heavy-duty project FastDS, which aims to make it easier to work with versioning in data science projects.

The problem with authentication of web sockets is that you can only authenticate a http request once against a authentication scheme. After that the authentication is cached and will always yield the same result.

A web socket connection starts over HTTP. A HTTP request with the Upgrade header is send to the back end. This request is then "upgraded" into a web socket that runs over the web socket pipeline. The main issue with web sockets is that you cannot set additional headers with this initial HTTP header. Therefore the authentication will fail and the request will be unauthenticated. The HTTP context of the initial request will last as long as the web socket connection is running.

The trick we do is that we add a stub authentication scheme:
