MIND CONTROL COPTERS!, Better Security, Ratings Systems, and Lightweight Reference

  1. Continuous Three-Dimensional Control of a Virtual Helicopter Using a Motor Imagery Based Brain-Computer Interface (PLOSone) — direct brain control is becoming a reality, tiny step by tiny step. Also: HELICOPTERS!
  2. Forward Secrecy for HTTPS — Google contributed a better HTTPS cipher suite to OpenSSL, one that doesn’t share keys between conversations. Yay the Goog for giving back.
  3. Ratings Systems (Quora) — very good answer from the VP of Engineering at Netflix about the purposes and effects of different ratings and feedback systems. Full of pithy and true guidelines like: Your users have a certain mental budget they will invest in your rating system. The more work you make each decision, the fewer decisions you will get. This is true in many contexts other than rating systems as well. You can’t randomly throw feedback mechanisms into your app, you must design them as deliberately and thoughtfully as the rest of your site.
  4. InstaCSS — very simple very useful reference site. Grod like simplicity.
