Django's Cached Template Loader

Quick tip on fixing an error that may confuse you. Namely, because in the settings file, we have to give string names - so errors are somewhat abstracted from your input.

Basically, when you give the argument to TEMPLATES["OPTIONS"]["loaders"],

• the argument is a list of loaders;
• for the cached loader, the first argument is the cached loader,
• but it needs 1+ args - what it's caching.
• You pass this as a tuple of the loader, and its args.

How to recover a dropped stash in Git?

1. Find the stash commits:

git log --graph --oneline --decorate $( git fsck --no-reflog | awk '/dangling commit/ {print $3}' )

This will show you all the commits at the tips of your commit graph which are no longer referenced from any branch or tag – every lost commit, including every stash commit you’ve ever created, will be somewhere in that graph.

Question:

What could I try for doing Test Impact Analysis for Python projects?

Answer:

There are a few libraries out there you could try. Here are some entrypoints:

• python-tia - this is my preference
• "Potential Alternatives" page in pytest-tia's docs. You can use this as a starting point to comparing alternatives.

I've self-educated as a developer; now almost 10 years into it, it's worked out for me. But why? What was the deciding factor?

Looking back, I think I can see the inflection point.

I had a mentor who helped me use interactive approaches, and test-driven development. This led to a test-driven mindset.

The core of this mindset is the empirical attitude: that you can know nothing without testing. I learned to iterate in a more directed way. And by always beginning with failing tests,
