Git Pull Request Hygiene

It seems that pretty much everyone is using some sort of UI for their git interactions.

Which is obviously fine, until they are about to create a commit, in which case it’s using the “add all changes”-button and commit.

Good PR hygiene starts with keeping your commits small and focused: check your changes and exclude everything that is not part of the UserStory per se.

That’s why I advocate the use of git add --patch which gives you fine-grained control of exactly what you’re going to commit!

Talk to the Duck

When confronted with a problem, don’t ask the person next to you for help right away, he’s probably doing something important as well!

Instead, first tell the duck about it - out loud. If you don’t get to a solution, start explaining your problem in more and more detail until it hits you. If the mere explanation led to a solution, you avoid unwillingly turning your colleague into a CardboardProgrammer.

Autohotkey Tutorial - hotkeys

First we’ll cover the basic Autohotkey hotkey syntax. Which is arguably already pretty confusing for newcomers in and by itself.

But we don’t stop there as after adding more and more hotkeys, it will also become harder and harder to think of new key combinations that are somehow still memorable. There is only so much you can do with the # (Windows) key etc.

Time for some creative hotkey combinations! ‘Advanced Hotkeys’ covers code snippets on how to run different scripts on single, double or triple key presses as well as how to differentiate between long(ish) key presses or mouse clicks. And more…

If this returns nothing, there is room for improvement there!

# Short version
git config --global core.pager "less -eFiJM~ -j3 --tabs=3"

# Not so short version

    .map(x => x * 10)
