I am happy to give you an interview or provide you with a consultation.
I am very interested in innovative ways to secure property and personal interactions: all the way from cryptography to user interfaces. I am not interested in trading, mining or building exchanges.

Github > Rubyforge

I have removed EMRPC project from Rubyforge because it is not fun to work with their fucked up API. Github is much nicer (just update a gemspec and wait for 10 minutes). Add github to your gem sources list (if you haven’t done it already): 

$ gem sources -a http://gems.github.com
Remember, that github names gems in form of “username-projectname”, not just a “projectname” as rubyforge does. To install EMRPC: 
$ sudo gem install oleganza-emrpc
