No, this is not a real Sinatra error :).
This is the personal homepage of Elad Meidar, a web developer and an entrepreneur specializing in Ruby on Rails. I hang around in Israel, and i am currently having the best time of my life over at Fiverr.com
I am a proud member of RailsBridge, Helping new Rails developers get into our world and also contributed a few Patches to the Ruby on Rails core.
For a while i was interested to see how many of the rails developers i know, use macs. After talking about this urge of mine with the awesome @hakunin we have decided to collect a bunch of our colleagues desktop portraits. almost everyone is on a mac (duh!).
Foolishly, i forgot to notate some of the pictures people sent me with the name of the developer, so if you recognize yours and want to link the image/title to somewhere, lemme know.
You're seeing this error because I think it is funny.
