I use git a lot for work and other projects, so I invested the time in creating some high quality aliases that really work for me. These just go in your bash profile (~/.bash_profile or ~/.bashrc or ~/.profile depending on your OS).

I see a lot of people go overboard with aliases, and then end up not using them. They're meant to cover 95% of the commands I use, not 100%.

alias gcam='git commit -am'
alias gs='git status'
alias gplr='git pull --rebase'
alias gpsh='git push'
alias gpo='git push -u origin `git symbolic-ref --short HEAD`'

These macros are designed to provide a literal notation for [immutable-js][1] using [sweetjs][2].

The most interesting being the Map literal

var map = im{"foo": "bar", "baz": "quux"};

This compiles to the 2d array version of Immutable.Map.

2015-01-29 Unofficial Relay FAQ

Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).

	Aloha, /r/Programming!

	Tomorrow, I'm interviewing RethinkDB's founder, Slava Akhmechet, for a podcast. Have any questions for him?
	Comment here or on Reddit and I'll ask him!

	There'll be a full text transcript of the interview posted next week, too, for those who aren't fond of podcasts.

	Thanks!
