Installing Adobe Air and Elance Tracker on Ubuntu 13.10 (Saucy Salamander) 64 bit
Update: Following instructions also work for Ubuntu 14.04 LTS Trusty Tahr 64 bit. After upgrading to Ubuntu 13.10 (Saucy) 64 bits, I had troubles installing Adobe Air and Elance Tracker air application. None of the guides available online worked for me. The guide that I used to install it on Ubuntu 13.04 didn’t work either.

Multiple file upload with Rails 3.2, paperclip, html5 and no javascript
Today, I was looking for a simple multiple file upload solution for Ruby on Rails 3.2 with paperclip 3.0.4 and found several jQuery and Flash solutions, like Uploadify or jQuery-File-Upload, buy they seemed to be too heavy and complicated for my case. I didn’t need asynchronous upload and other features they provide, I only needed really simple (ideally pure html) solution to save several images for my Item model with regular form submit, but with possibility to select all images at once (in one input field).

Testing authorization using RSpec parametrized shared examples
I have a rails app, that uses Devise for authentication and CanCan for authorization. There is a group of controllers in my application, that should be accessible by administrators only. I was thinking about a DRY way to test these resources and their accessibility by administrators only (using request specs with RSpec and Capybara). The idea is to have shared examples, which try to visit resource url as unauthenicated user, authenicated non-privileged user and administrator, and check if desired resource was loaded or not.
