Nice Hacks

• Using git bisect for finding the "broken commit": https://stackoverflow.com/a/4714297/1948946
• Using git pickaxe for searching commits that added a certain string: https://gist.github.com/phil-blain/2a1cf81a0030001d33158e44a35ceda6

Migrate from Bitbucket to GitHub

1. Make sure your SSH public key is here: https://github.com/settings/keys (you will find a .pub file in ~/.ssh in your machine)
2. Make sure you have custom routing for your new organization email (https://github.com/settings/notifications)
3. Run git config --global user.email and git config --global user.name to make sure your name and email are correct
4. Use the GitHub Import tool (temporarily remove 2-factor auth from BitBucket account) as this will migrate all the branches/tags, etc.

Event Loop

• SetInmediate vs. nextTick: In essence, the names should be swapped. process.nextTick() fires more immediately than setImmediate(), but this is an artifact of the past which is unlikely to change. We recommend developers use setImmediate() in all cases. https://nodejs.org/en/docs/guides/event-loop-timers-and-nexttick/#process-nexttick-vs-setimmediate

canary (canary test, canary deployment): In software testing, a canary is a push of programming code changes to a small group of end users who are unaware that they are receiving new code. Because the canary is only distributed to a small number of users, its impact is relatively small and changes can be reversed quickly should the new code prove to be buggy. Canary tests, which are often automated, are run after testing in a sandbox environment has been completed.

greenfield: In many disciplines a greenfield project is one that lacks constraints imposed by prior work. The analogy is to that of construction on greenfield land where there is no need to work within the constraints of existing buildings or infrastructure.

Cattle-not-pets: You should treat your servers as cattle, not pets. Servers are immutable. Once created they cannot be changed. To be changed they need to be generated.
