Easiest Ruby GeoIP gem

http://github.com/cjheath/geoip/tree/master

There are quite a few geoip gems out there that use the free Maxmind db, but most of the seem to require you to compile another application (available from Maxmind) to use it… It’s too difficult and not even necessary. The Maxmind db is in a binary format, but it is very easy to read… Check out geoip gem on Github for a ruby gem that reads the Maxmind ip database and doesn’t even require compilation!

I recently covered Ruby block basics in my post, More Advanced Ruby Method Arguments – Hashes And Block Basics. I mentioned that blocks are not really method arguments and also covered the two different types of block syntax. Towards the end of that post I promised to examine Ruby blocks more deeply and I am going to do that here. In my opinion there are several interesting things about blocks…

A Wealth Of Ruby Loops And Iterators

http://www.skorks.com/2009/09/a-wealth-of-ruby-loops-and-iterators/

I remember when I first started looking at Ruby, I’d be browsing some code and see yet another way of looping/iterating over stuff. Whenever that would happen I would think, “…Ruby sure has a lot of different ways to iterate over things”, but I also remember wishing that someone would just put all the different ways to loop and iterate over stuff together so that you don’t have to discover them in a piecemeal fashion.

bullet - A rails plugin/gem to kill N+1 queries and unused eager loadings

http://github.com/flyerhzm/bullet/tree/master

The flyerhzm-bullet gem is designed to help you increase your application’s performance by reducing the number of queries it makes. It will watch your queries while you develop your application and notify you when you should add eager loading (N+1 queries) or when you’re using eager loading that isn’t necessary. It also provides some notification, such as javascript alert, browser console.log, bullet log, rails log and growl. [more inside]
