After a mere 10 years in limbo, I've finally finished Homespring.cloud, an online interactive debugger for the Homespring language, based on my JavaScript interpreter. It makes writing and running Homespring programs easier to learn and much more fun!
Mar 4th: It's from a few years back, but "How much should you lie?" is a great piece about startup story telling and what's acceptable.
Feb 28th: It's honestly pretty magical what you can do in CSS these days. You don't need JS for so many things now - and centering content is pretty easy!
Feb 28th: Not only are the curling stones used at the Olympics (and pretty much everywhere) made by a single company in Scotland, they took the stones used in Cortina and cut them down into little commemorative mini stones (which unfortunately sold out right away)
Feb 28th: I didn't realize that the apple 'sleeping light' pulsed at a human breathing rate - I love these little details.
Feb 21st: I'm not great at the dialed.gg color memory/matching game, probably due to being color blind, but it's pretty fun!
Jan 30th: I've been thinking about Logo/Turtle recently and was looking for some good Scratch-like environments for kids to get started in (besides Scratch's own Pen extension). Trinket looks interesting (as an intro to Python), but Turtle Blocks is just what I was looking for. The official hosted version is extremely slow to load for some reason, but it's open source - you can host your own copy and add extensions.
Jan 21st: Nikita's critique of the Mac OS Tahoe icons is accurate and awful. The slow enshittification of everything.
MapToPoster is a fun little project that takes open street map data and creates beautiful posters of different cities/locations. More geo projects like this, please.
Another year, another 121 books completed, or about 1 every 3 days. My 2025 reading list has a very brief review/summary of each one.
Highlights were The Thursday Murder Club by Richard Osman, Piranesi by Susanna Clarke, The Repeat Room by Jesse Ball and Little Eyes by Samanta Schweblin.
While I strive not to be, I can be pretty inconsistent in my reading pace. More books take 1 day to read than any other length of time, with 72% in 3 days or less and 93% within a week. The longest took a full 23 days (because I was on a vacation where I didn't read much).
I read much less on vacation than when I'm at home, and I read the most when I get really dug into a series I love - October was 13 books from Mick Herron's Slough House.
With ~20 years of my reading history tracked, my biggest take away is that there are still so many great books to find :)
