Four short links: 6 September 2010

Akihabara (Github) — open source (GPL2 and MIT dual-licensed) HTML5/Javascript engine for classic arcade games. (via chadfowler on Twitter)
Eureka Streams — open sourced Java app for enterprise Twitter-like activity: build a profile, join groups, post updates, subscribe to updates from individuals or groups. (via dlpeters on Twitter)
Open Microbiome — hoping to build open tools, standard samples, data, and metadata for analysis of the microbiome (all the microorganisms that live in, on, and with macroorganisms like us). Early days, but glad to see people are already thinking of building this research open from the ground up. And if you think sequencing the human genome gave us a lot of data we struggle to find patterns in, wait until you start including microorganisms: we have 10x as many bacteria in us as we have cells and the species variety is vast.

Habits of Mathematical Minds — fantastic list of skills and approaches that are hallmarks of many successful minds, not just in mathematics. (via ddmeyer on Twitter)
