fork a repo manually (set source as upstream origin) rather than with the "fork" button. e.g. for in github when you want to fork a project twice.

Ripped off from adrianshort.org

List curent remotes

$ git remote -v

origin  https://github.com/hakimel/reveal.js.git (fetch)
origin  https://github.com/hakimel/reveal.js.git (push)

Rename origin to upstream and add our new empty repo as the origin.

PostgreSQL command line cheatsheet

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

  • -E: will describe the underlaying queries of the \ commands (cool for learning!)
  • -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Comparing two ways to load non-critical CSS

I wanted to figure out the fastest way to load non-critical CSS so that the impact on initial page drawing is minimal.

TL;DR: Here's the solution I ended up with: https://github.com/filamentgroup/loadCSS/

For async JavaScript file requests, we have the async attribute to make this easy, but CSS file requests have no similar standard mechanism (at least, none that will still apply the CSS after loading - here are some async CSS loading conditions that do apply when CSS is inapplicable to media: https://gist.github.com/igrigorik/2935269#file-notes-md ).

Seems there are a couple ways to load and apply a CSS file in a non-blocking manner:
