- My notes from this talk by Alexander Petros at Big Sky DevCon 2026. Alex starts by noting how “modernize” used to mean something along the lines of “update this thing that was made before I was born”. But now “modernize” means something more like “update this thing from 5-10...

- End of July? Seriously? Feels like yesterday when I celebrated New Year’s Eve, and all of a sudden it is the end of July. Can we all slow down a little, please? Not a little. Slow down! You, time, the world. Pretty please! I’m in a good mood today, but not in a good one to write...
- There are two wolves inside of me, lol. Some days I want to be a “designer”. Other days I want to be a “developer”. On the days I find myself wanting to feed the developer, it’s often because making something “work” seems easier (and more impressive) than making something...

- Pretty big month for the web. Tons of great posts came out, Apple WWDC took place and a few shocking acquisitions happened as well. I have been travelling for work and with family this month a lot so no other crazy updates from my personal life this month, but as always great...
- I recently gave a talk on customizable (as in fully-stylable) <select>, and as I was building demos I realised there's a sizing 'pattern' that's almost always the-one-you-want, but it took me a long time to figure out how to do it in CSS. Well, I say I figured it out. I actually...
