I built a new web page for my work history. A single HTML file with no dependencies or build process. Just index.html. All the CSS is in the <head> with support for system display modes (light/dark), a few media queries for mobile, and some web fonts hosted on my CDN.

One of my favorite details from the new site that we just shipped, are these lil' tiles. So fun to make. I've never done any kind of icon/illustration design professionally, but I think these came out pretty nice👀

Building a good looking webpage with just a single html file and < 100 lines of css in the <head> is extremely satisfying in 2024. Also not using classnames and just styling element types is elite AF.

Popular opinion?: Apple Music should be the best music service for people who already use Apple products, but it’s not. The search is dogshit, navigating the UI is buggy AF (and weird!), discovery features aren’t mature, and it’s not joyful to use on any platform.

@matiasbaldanza That’s certainly a nice side effect. The biggest reason is that lately, the default has been to add too much complexity for simple things. I believe that the complexity of the internals should scale in proportion to the complexity of the result.
