Full Stack Fest Barcelona CFP open

I’m one of the organizers of Full Stack Fest, a conference born from joining the quite successful Baruco and FutureJS. It takes place in the wonderful city of Barcelona this September 1-5. We’re committed to making the conference as diverse as possible, and looking at the previous edition’s attendance statistics, we feel like we can do better. We definitely strive to have a speaker roster and attendee profile as diverse as possible, as this makes for a much richer experience and higher quality.

Send in your proposals and stay tuned for Monday!

New Datafiles for Top Football Leagues (en,de,es,fr,it) - e.g. use $ sportdb new top

Hello, I’ve added some more datafiles that let you build your own football.db - using free open public domain datasets - with a single command e.g. $ sportdb new fr2014-15. The new datafiles include: de.rb and de2014-15.rb; es.rb and es2014-15.rb; it.rb and it2014-15.rb; fr.rb and fr2014-15.rb; at.rb and at2014-15.rb; top.rb and top2014-15.rb (includes top leagues e.g. en,de,es,fr,it). Cheers.

CanCan Overview

CanCan was originally introduced by Ryan Bates in 2009 and was taken over by Bryan Rite. It’s been a while since I’ve seen a post about it so I decided to do a write up on my opinion of it. See the details at Thoughts on CanCan
