Visual information is not structured as computers would like. Processing visual data in code effectively requires a simply measurable hook -- the T-shape described by (binocular) eyes/nose/mouth, for instance, or the shadow patterns inside eye sockets. But re. visual information from sporting events, Luis Sobrecueva realized something cool: most games are played on a grass surface; so items moving on the surface (ball, people) can be detected as less-green fields. so he tossed together a cool Canvas with some sweet JavaScript that looks for the ungreen, and stitches the ungreen together...

Isolated testing lets you quickly find and correct particular problems, but does a poor job locating site-wide and integration errors. For end-to-end functionality testing, Zombie.js makes quick checks easy -- and, besides, lets Daniel Mohl use his very own ExpectThat project, a CoffeeScript library for writing expressive, self-documenting unit tests. In this post Daniel explains exactly how to use ExpectThat with Zombie.js, with a simple code example.

I really love Python & its wonderful frameworks - they brought me pure joy & satisfaction for the past 6 years. However, I'm forced to acknowledge that the times they are a-changin: logic moves back to the client-side, leaving the server-side to do almost nothing (just data access, usually). Further more, the server side turned into a series of disporate API's, which the client consumes, provided by different vendors - so now even the data access moves to the client, which talks directly with datastore providers.

In the 1st post I explained my assumption that there is no more need for server back-end for user-facing applications, which should just be client-side applications accessing cloud API's for resources & services (whether our own or 3rd-party). I'm targeting the Web as initial platform for the example application, so I chose to write the application in JavaScript. The person who did the most to revive & evangalize JavaScript - Douglas Crockford - is also the one who pointed out the many weaknesses it has, due mainly to the very short time in which it was developed. These weaknesses cause you to use overly-complex & error-prone syntax which is a real bummer for someone switching from Python.
