We chatted a little bit, and just sat for a little bit, and she occasionally reached down to poke at me or nibble on my arm. Then she explained object-oriented programming to me ( Read more... )

Random request, but does anyone happen to have python (or javascript) code for finding the area of the convex hull for a series of points?

This realization, regarding programming, which, like natural language, can, in the hands of the unskilled, contain clauses that are, though excessive, meaning ( Read more... )

Hey, programmer folks. I'm doing that crazy thing where you use PHP to take users' form input, use it to generate SQL queries, and later get info out of the database and display it on a page.

This doesn't ensure equal cell sizes, but it comes close. For this web-based study we wanted to have different numbers in different conditions, but rather than just assigning to the cells randomly ( Read more... )
