Cute Math, Fast Slo-Mo, Open Source HVAC, xkcd Hack

  1. Inside-Out Multiplication Table — very cool way to view the patterns of factors. Math is beauty with subscripts.
  2. High-Speed Camera — capture 100 frames at up to 1M frames/second. The sample videos, of a bullet liquefying on impact and a shotgun string boiling past, are stunning. The Makezine high-speed photography kit is the cheap amateur version.
  3. Open Source Energy Management for Commercial Buildingsopen source project to enable interoperable applications for integrated Building Automation Systems (BAS). From NovusEdge. I wonder how they’re planning to spread their open source and use it to disrupt. (via earth2tech and timoreilly on Twitter)
  4. xkcd Knapsack Solution — for those of you who like literal Python geeking with your comics. Have a great weekend!
