This year in my ITP Introduction to Computational Media course, we added an two new weeks of material about Strings, server-side programming, and databases. These tutorials can be found here: Part I, Part II.

The most common question I’ve received since then is “What if I want to request the data continuously in draw()?” And to answer this question, I’ve posted a new tutorial on the Processing wiki page about Threads:

In addition, related to my last post about streaming video in Processing, you can download an example that receives the video stream in separate thread.
