  • Snooping on Internet Archive’s Wayback Machine bot

    I’m reading Jon Duckett’s “PHP & MYSQL” and got up to a section where he discusses $_SERVER, which contains info on HTTP headers, etc. I thought it might be fun to see what Internet Archive’s Wayback Machine bot looks like in terms of this. So, here’s my take on dumping parts of $_SERVER: https://github.com/fadend/server-vars-php/blob/main/server_vars.php. Hopefully…

  • Wolfram’s Cellular Automata

I was inspired to do this because in looking for costs to cut, I decided to stop paying for Photobucket.

    Mandelbrot Set in Autoplot

    My older brother Jeremy was the first person to help me with programming. (And I’ve never stopped asking him for programming advice since then!) My first computer was a Commodore 128 that my mom picked up at a garage sale (it turns out from one of Jeremy’s high school friends); it was quite ancient even…
