Random Hacks of Kindness is a global initiative that was started by Google, Microsoft, Yahoo, NASA and the World Bank.
It brings hackers together with experts in things like bushfire response, climate change and other natural disasters. The aim is to spend the weekend building practical, open source solutions to real world problems.
On the 1st and 2nd of June, 32 cities around the world will be joining in to Hack for Humanity. If you're in Sydney - it would be great to see you at the RHoK Sydney event in the Sydney CBD.
