Delightful coding lessons in Ruby. From Gregory Brown's Practicing Ruby newsletter.

This Columbia University virology course is offered each year in the spring semester. The basic thesis of the course is that all viruses adopt a common strategy. The strategy is simple: 1. Viral genomes are contained in metastable particles. 2. Genomes encode gene products that promote an infectious...

Code that writes code. Add more powerful abstractions and reduce duplication through Ruby that writes Ruby!

A new class is starting at virology blog: Virology 101. I began this blog in 2004, to give back what I’ve learned from studying viruses for 30+ years. I’ve written many posts on basic virology, but they tend to disappear with time. To remedy this problem, I’ve collected all these posts with links...

A koan-style tutorial in Java for Neo4j. This set of Koans provides a hands-on tutorial for learning the Neo4j open source graph database. It's part of a more comprehensive tutorial often presented by the authors and other folks. The Koan idea was borrowed from the Ruby Koans which provide a number...
