dont fuck up merges to gaia

1. do you have r+ from a peer?
2. are all the tests green in travis?
3. have you squashed all the commits?
4. have you updated the commit log to include r=foo?
5. is the commit log of the form "Bug XXXXXX - TITLE OF BUG r=foo" ?
6. is the branch good to merge, or does it need to be rebased?

ok, go ahead and merge using the github interface.

Sometimes a Gaia bug only shows up in User, not Engineer, builds.

How to get this to a debuggable state?

This works for me for 2.1 aurora builds. It might be wildly inaccurate by the time you read this ^_^

1. Enable developer menu

• this recently changed; you have to go into Device information > more information, then scroll to the bottom

2. Enable ADB and Devtools debugging inside Developer.
3. Enable debugging of certified apps

I want to improve how I document the work I do.

Idea: for each bug, keep a text file collecting my thoughts.

Also: create a pull request from my branch to my own fork, and put comments in there on the diff itself.

Maybe this will help me to recall earlier decisions in more detail.

Let's see :-)

1. declarative programming sucks horribly

• because you have to, in your brain, understand every fact in the system and how they interact
• this is not how human brains work, we think in narratives, in linear flows
• this is why it's impossible to debug CSS (or Puppet, or XML...)

2. there is a fix

• instead of a huge graph of possible interacting facts,
• just eliminate the cascade as much as humanly possible

3. there are two ways

• one is to overspecify every property of every node. this is how less/sass work.
• two is to use lots of generic classes, like how css frameworks work (oocss, etc).

I have like, so many old local branches. how to get rid of the ones I don't need any more?

courtesy of [1], the answer is: "delete the ones that have been merged":

git branch --merged | grep -v \* | xargs git branch -D
