I have added some new apps to my Web site. One, a bit serious, the other, less so.<\/p>\n

The serious one: a technology demonstration, showing that it is not black magic to use a Web camera and try to extract from its feed an estimate of a person’s heart rate and (less reliably) respiratory rate. The measurement is not perfect, of course, but it works surprisingly well at least some of the time.<\/p>\n

Meanwhile, I also resurrected an old project of mine, one I initially did in 1993: itself a resurrection of an even older game from back in the heroic 8-bit days. I was inspired by a DOS version on Usenet, itself derived from an earlier X11 version; it became my first “full-featured” Visual C++ project, originally developed for Windows 3.1. A 32-bit version followed two years later, and that was the basis of my current, Web-based reimplementation. I called my version Rubble Rush, to avoid infringing on the original’s (still extant, as far as I know) trademark.<\/p>\n

These implementations also showcase how easy it is, using modern JavaScript, to develop solutions with real-time interactivity, also using real-time media streams to boot.<\/p>\n<\/fb:like>","protected":false},"excerpt":{"rendered":"
