How recursion got into programming: a comedy of errors

No Copyright Intended
On October 26, a YouTube user named crimewriter95 posted a full-length version of Pulp Fiction, rearranged in chronological order. A couple things struck me about this video. First, I’m surprised that a full-length, 2.5-hour very slight remix of a popular film can survive on YouTube for over six weeks without getting…

Photoshop’s journey to the web

For each question, the left box contains some code, while the right box contains code that purports to do the same thing, but that illustrates a particular optimization.
