I just launched Hakiri—a web app that gives you peace of mind about your web projects' security. Just select versions of technologies that you use in your projects and Hakiri will notify you via email when new vulnerabilities are discovered so you can update quickly.

Hakiri currently supports a limited set of technologies like Ruby/Rails, Postgres, Java, etc. I plan to add more soon.

I just released an update for Almanac mountable blog engine. Version 0.9 includes a bunch of bug fixes as well as Disqus commenting support. Give it a try!

I just published an article on Machine Learning in Ruby. It uses the JRuby Mahout gem to show how to create a simple recommendation engine.

I just pushed the first public version of Jruby Mahout gem.

Jruby Mahout is a gem that unleashes the power of Apache Mahout in the world of Jruby. Mahout is a superior machine learning library written in Java. It deals with recommendations, clustering and classification machine learning problems at scale. Until now it was difficult to use it in Ruby projects.
