I created a space-themed browser game called Wild Black Yonder. Due to neglect, it has languished; its only denizens are wayward spambots who broke the captchas and managed to create accounts.
Perhaps someday I will return to this project. In the meantime, feel free to log in and play. I am open to any feedback, good or bad. I don't mind sharing the code either, so feel free to ask about that.
This script checks my website for broken hyperlinks, of which there are many. The php code is short and can be modified for your own website. Download the necessary files by right clicking here and selecting "save as".
This script models heat flow in a grid discretely. No differential equations needed. It's very simple and based on an undergrad homework assignment. I redid it on a whim.
This script uses a web crawler to help the user search for a person's phone number. Just enter the name to search for and then submit and the script will crawl Yahoo and Bing, searching the results for any phone number-like strings. I created this to play around with web crawlers.
