Great Interfaces: The Scale of the Universe

February 11, 2012 I love how much information is communicated in such a simple interface. I also like the fact that data appears when it is needed, but doesn't clutter up the screen when it is not needed.

cucumber says, "no such file to load -- spec/expectations"

Setting up a Rails3 application quickly, I ran in to this error... no such file to load -- spec/expectations easy fix... I had gem 'rspec' but needed to add gem 'rspec-rails'

May 21, 2011
Here's how I typically setup my rails environments. NOTE: I don't include stored procedure or view permissions because Rails doesn't ever use those. Wouldn't it be great if Rails used views or stored procedures? Actually, I kinda like it the way it is. Stored Procedures are nice but the tradeoff, IE having business logic in the app and in the...

Capistrano says, "sh: bundle: not found"

"Twilio": apparently offers a "telephone api": and also an SMS API. I get how you could easily set up an SMS API. Pretty cool stuff. But what amazed me what the idea that someone could call a telephone number, which would result in a post to my website... and I would respond with...
