  • Make XML Sitemaps Easily with PHP!
    I am a huge fan of simple solutions for the web. So many solutions require tons of tooling or a giant content management system and those things are brittle over the long haul of time. XML Sitemaps help search engines, notably Google but other search engines too. In October 2009 I created this code to…

  • Adding tags to blog posts retroactively.
    I’ve been reflecting my instagram posts back to this blog for a while now. One of the conventions there is mentioning people with the @mention and hashtagging posts with #hashtags. It has bothered me for a while that I didn’t ingest those tags and mentions in some manner. I left this lay for a long…

  • CALL CHAR
    100 CALL CLEAR 110 CALL CHAR(96, “FFFFFFFFFFFFFFFF”) 120 CALL CHAR(42, “0F0F0F0F0F0F0F0F”) 130 CALL HCHAR(12,17,42) 140 CALL VCHAR(14,17,96) 150 FOR DELAY=1 TO 500 160 NEXT DELAY The first time I ever programmed it was from this page.

  • Color the Smiley
    Over the years I have made a lot of little web experiments and geegaws. I’ve made hangman games and drawing programs and random text generators. At one place I worked I helped make a thing that would turn an uploaded photo of a face into a Terminator face! I’ve made so many of these kind…

  • I blogged for 17 years and all I got were these lousy Markov chains.
    In which I turn my experiments with turning written text into Markovify-generated sentences into a cool Twitter bot.


  • Markov Chains are hilarious.
    I’ve wanted to make Markov chain generated sentences based on this blog for a long while. Wednesday night, I did. It took me under an hour! Why have I avoided it thinking it’d be difficult? Probably I thought it’d take a long time and would be lame. NOT SO First, I exported the contents of…
