This Jekyll plugin is heavily inspired by Gerby, the tool used to build the Stacks Project and Kerodon. It allows you to build math textbooks as static websites which require no complex infrastructure to run.

Usually Resque workers work on queues in the given order (if there is something in the first, work it, otherwise if the there is something in the second, work on it, and so on). This plugin randomizes the order of the queues based on weights, so that a given queue will be the first queue to try b...

Chef report handler that uses pony to send an email. Based on Mathieu Sauve-Frankel's chef-handler-mail

Ruby developers have, for as long as I can remember, had a disheveled heap of scientific and mathematical libraries - many of which operate in pure ruby code. Given a problem we either kludge together some cobbled mess or turn to Python/R/etc. And to this I say no more! rb_maxima allows a ruby de...

This is a simple gem that helps to implement a couple of math operations such as addition, substraction, multiplication, division, roots, power and percents. Enjoy!

Kame (Japanese for turtle) is an implementation of the Logo programming language built as a challenge to myself. I wanted a simple way to introduce programming in Ruby to my daughter and thought this would be fun. With Kame, you control the movement of a turtle around the screen by programming co...
