Programming From Angela Bradley, your About Programming Editor Dear Subscriber, Welcome to this week's edition of your About Programming Newsletter. This week we take a look at geometry and PHP, Kinect, adding a grab bar to the TSplitter, and the JVM language summit. Have a great week! Geometry & PHP In this first part of a two part tutorial, we explore how to calculate Pi, how to convert from degrees to radians, and how to calculate the sine, cosine and tangent. All of these are very useful functions if you need to make geometric calculations.

An array of four microphones make it easy to locate a sound source, and the 3D infra red laser can map out a space around it. Think of it as a clever and programmable web cam. Add A Grab Bar To The TSplitter The TSplitter Delphi control does a nice job of allowing the user to resize user elements like panels on a form to make the user interface more flexible. A nice to have for a splitter would be to have a grab bar - and here's how to easily paint one on all your splitters - without having to redesign your user interface. The JVM Language Summit 2012 The date for the annual JVM Language Summit has been set for July 30th-August 1st, 2012 at Oracle's Santa Clara campus. It's a chance for VM implementers to get together and talk about "language design and implementation on the JVM, and the present and future capabilities of the JVM itself". The agenda will be updated when the speakers have been finalized.
