Here is a list of resources that I have read either fully, or at least to an extent with which I am comfortable with endorsing them.

I've used these resources in different ways:

Direct application: Some bits and pieces of advice can be applied very directly.
Reflection: For organizational things, sometimes I would try to write down how I felt my work environment mirrored, and how it differed from the situation described in some work. Writing things down is a useful forcing function to think clearly.
1:1 discussions with my manager: We'd take the first 15-20 minutes of

Programming as Theory Building

Peter Naur

Peter Naur's classic 1985 essay "Programming as Theory Building" argues that a program is not its source code. A program is a shared mental construct (he uses the word theory) that lives in the minds of the people who work on it. If you lose the people, you lose the program. The code is merely a written representation of the program, and it's lossy, so you can't reconstruct

Stuff I wish I'd known sooner about service workers

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.

I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.

Use Canary for development instead of Chrome stable

~~Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.~~
