When Postgresql complains user does not exist
View gist:e680b5a22d9b4d76f0f2
This can happen when active directory or someone else installed postgresql without proper right like a sudo brew install postgres instead of a brew install postgres.
To fix you can entirely destroy the db and recreate it with your user:
rm -rf /usr/local/var/postgres && initdb /usr/local/var/postgres -E utf8

140 char limit sucks
Node.js matters because:
- JS programmers now have access to their language on the server (ignoring Netscape server for a minute).
- concurrent programming is the hot topic "du jour" and languages that embrace events like JS make for a good mix with this topic "du jour"
- Node.js is faster than Ruby yet still very expressive
- JS has a good chance to become the lingua franca for programmers much like PHP is for the web today.
You can’t perform that action at this time.
