So, Brit is smart and figured out some dumb stuff

• El Capitan breaks how Postgres previously loaded and ran ...
• So basically we have to update homebrew, and then reinstall postgres ...

1. Run brew update - Pull down the latest changes to homebrew for El Capitan
2. Run brew upgrade postgres - Update to the latest postgres release in homebrew
3. Run launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist - Stop the old version of postgres
4. Run launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist - Start the new postgres database

Read the manual page for a unix command with man or woman. What command did you read about? What does it do?

I read about grep which can be used to search inside a file or files for specific text.  We talked about it a bit in class but I learned that it can also search for regular expressions.  This makes grep an extremely powerful command line tool which allows you to easily find text inside your code.

I've used it before a little at work but not enough to consider myself a "power user."  I am interested to learn how often people use this in the Ruby and Rails world.
