Random Hacks of Kindness, or RHoK, is a joint Microsoft, Google, Yahoo!, HP, NASA, and World Bank initiative that teams subject-matter experts on global challenges with technical expert volunteers for a 48-hour hackathon. This weekend, June 2-3, RHoK events will occur in over 20 cities around the world.

This coming weekend marks the 6th edition of RHoK. What started as an experiment in 2009 has now grown into a global movement involving an international community of 4,000+ people in 50 cities on 6 continents.
