git rebase –edit-todo

As of git 1.8.0, git rebase learned “–edit-todo”. This is something you can use to edit the todo list while in the middle of a rebase. For example, if you mark a commit as e (for edit) when you initially edit the todo list, when git stops at that commit allowing you to edit it you can then git rebase --edit-todo to edit the remaining portion of the todo list.

Dave suggested to_string is for Java developers. Cathy will look into this more today and report back.

Interesting

• Using jasmine’s pretty-print with ember.js was causing the browser to crash as it was recursively going through the object graph trying to construct a string representation of the object. Defining Em.Object.Prototype.jasmineToString() to return this.toString() fixed this.
• We were having trouble screen sharing to some of the mac minis connected to the TVs, the screen sharing app would hang on “receiving first screen”. The fix for this is to command+k from finder and enter vnc://machine-name
• Bootswatch is cool. It contains a bunch of different styles for Bootstrap.
• Corey Innis has a fork of bootstrap which removes classes like span12

“Brent and Kris asked if anyone had encountered an after_destroy callback being called twice?”

“Joe asked about how to set default_url_options for? There are no mailers involved as far as he knew.”

“New Lee asked about were there any updates/alternatives for AccessList as the gem is causing him grief with sorting.”

Ian knew of an alternative to AccessTree, Lee is still looking.

Interesting Things

• Jonathon pointed out that background-color: cover and :clipping were useful for playing with background images
• New Lee brought up that if you’re using a form builder on a collection Rails will create a hidden for ID which will always get inserted (and may cause a problem if you’re nesting things in a ul or table). To get around this put in a hidden for ID in an appropriate place and Rails will stop generating one.
• Jonathon ended up being pointed towards Heydown as an alternative to ShowOff for presentations by Davis
