Four short links: 16 December 2014

1. Effectively Managing Memory at Gmail Scale — how they gathered data, how Javascript memory management works, and what they did to nail down leaks.
2. tigon — an open-source, real-time, low-latency, high-throughput stream processing framework.
3. Robo Brain — machine knowledge of the real world for robots. (via MIT Technology Review)
4. The Structure and Interpretation of the Computer Science Curriculum — convincing argument for teaching intro to programming with Scheme, but not using the classic text SICP.

Update: the original fourth link to Depeche Mood led only to a README on GitHub; we’ve replaced it with a new link.
