I made a coloring book! It's called Color the Counties (Or Equivalents): A silly map coloring book, made using Python and shapefiles from the U.S. Census Bureau. You can download a PDF copy or check out the online version. I have also made
In this post, I will explain how to make a PostScript version of the Minnesota state flag, both full-color and black-and-white line-art versions, suitable for printing. If you don't care about the code and just want the printable files, ski…
I made another thing: Float Explorer! This is a simple web app that shows you how a floating-point number is stored in your computer's memory. For example, consider the number 44.0457.1 In your computer, this number is represented as a doub…
Happy belated π Day! π Day is the 14th of March, i.e. 03-14 both the U.S. or ISO 8601 date formats. Two times in the past, I have posted some kind of method (not necessarily efficient) to approximate π as a π Day celebration: This year's en…
Yeah, if you have or frequently interact with children, you are probably familiar with the nonsense saying six seven. Is this a ridiculously silly meme? Of course it is, but so is (for example) trying to trick people into watching a particu…
Happy New Year—under the ISO week date calendar, that is! As I explained exactly 52 weeks ago, a year in the ISO week date calendar is made up of exactly 52 or 53 weeks, so that every week (Monday through Sunday) is in the same year. So eve…

I'm now indisputably middle-aged, and my eyesight isn't what it used to be. Specifically, I get very frustrated when text on screens contrasts poorly with background colors. A few years ago, I made an JavaScript color contract checker. You
I can enthusiastically recommend "Oh Shit, Git!" by @ksylor and @b0rk . Twice in the last two days I have consulted this zine to fix silly #git mistakes I have made. https://wizardzines.com/zines/oh-shit-git/ They have a no-swears version,
Anyone else keep accidentally going to "Missouri Digital News" when trying to get to MDN (Mozilla Developer Network) web docs? #programming #webdesign — Chris Phan, 2025-11-12 / 2025-W46-3T08:48:43-06:00 / 0x69149e4b I made a thing: https:/…
I think Unix time can be a lot of fun! If you don't know what Unix time is, it's the way a lot of computers (anything running Unix or Linux, which includes modern Macs, iPads, iPhones, Android devices, and so much more) keep track of time,
I made a new thing: Pwn Checker, a TUI app to check whether a password appears in Pwned Passwords' database of breached passwords. Of course, most people would be justifiably reluctant to send their passwords to a third party. However, that…
