I've read some things recently about choosing the right tool for the job, from a technology and programming language perspective. Most recently it was a post by Jeremy Bowers.
In it, he pokes at Python's weaknesses, but he isn't really writing about Python (as he says …
Raspberry Pi Pico Apology Button
When playing Call of Duty, I like "hardcore" mode, where a bullet or two is enough to send someone off to respawn land rather than having to empty half a clip. That mode also allows for friendly fire, which is a challenge. I appreciate that the game starts reflecting damage …
Thoughts on A Philosophy of Software Design
John Ousterhout's A Philosophy of Software Design sometimes aligned with and other times challenged my opinions about building software. The overall theme could be summarized with a Ray Ozzie quote: "Complexity kills. It sucks the life out of developers, it makes products difficult to plan, build and test, it introduces …

I encountered the following quote by Clive Thompson a while back:

Review of "Waxing On: The Karate Kid and Me"
Hollywood memoirs aren't things I normally read. I like movies, but usually I prefer the characters to the actors, so I'm fine being ignorant. Waxing On: The Karate Kid and Me by Ralph Macchio ended up in my hands after helping a neighbor with a computer problem. The problem was …
Experimenting with Stable Diffusion on my own machine
AI generated artwork has been in the news a lot lately, from the person who won an art contest with a computer-generated image, to Microsoft recently announcing that they'd include AI image generation in their Bing search engine. I've fiddled a little with online services for AI image generation, but …
PyCon US 2022
I wrapped up my participation in this year's PyCon last night. Being in Salt Lake City was great, since that's just a half-hour drive from my house, but it also means that I don't have the "completely focused on this" experience that traveling to a conference gives you. For example …
