First, read https://raw.githubusercontent.com/nicl/nicl.github.com/master/_posts/2018-07-12-branching.md.

Now let's take an example from DCR:

https://github.com/guardian/dotcom-rendering/blob/master/src/web/components/MediaMeta.tsx

This file handles media meta for galleries, photos, and videos. It is an example of what the blog post is talking about: it handles different things but doesn't keep branches separate.

To illustrate, look at the following:

Git commands sufficient for 99.9% of the time:

git status
git add -A
git branch
git checkout [-b]
git rebase [-i] master // interactive rebase is amazing
git reset HEAD [file] // when I accidentally add something
git reset HEAD^1 // for when you accidentally commit on master

If you were to draw your code flow as a graph, what would it look like?

It's a useful question I've found in discerning what a good and bad architecture looks like.

Consider, the following two cases:

1)  /\

/ \

How I write Scala

Note, this is a living document. If there are bits of Scala you think deserve to be called 'good' or 'bad' let me know and I'll add them to the discussion below.
