I’d never used the TikTok app in my life, but I just uploaded a video and now I feel famous.
The internet has warped my perception of numbers, but ~3,000 people seeing my thing is CRAZY

It's so easy for personal biases to become systems if you aren't careful. I was testing my name-identification heuristics and look which names it doesn't think are names. (Spoiler: It's the ones with accents.)

I've been leaning into very personal branding. Shuffle Buddy was made by me, for you.
I plan to share it via word-of-mouth, face-to-face at actual meetups. I am designing landing pages with my face all over. Even the app itself has a very prominent photo of me on the home screen.

Why did I include a very prominent photo of myself in the blog design? It's not narcissism. It's a marker against AI slop.
The article exists primarily for the purposes of SEO, but it's also a real article with real advice written by a real person.

I probably spent ~6 hours designing this multi-select dropdown menu, and it still has major issues that need to be fixed.
Programmers know how long it takes to build things that users should take for granted.

Looking back at "Clown School", an interactive math textbook I started building a while ago, and I am *shocked* by how good it is. Past me cooked.
Are there people who would pay for this?

I love being a color DJ. Left hand on the keyboard, right hand on the pen.
It was really satisfying to master the skill of choosing colors seamlessly while speaking.

I built a React app using @tldraw.com that assigns the number keys to different pen colors so that I can color-code my math while talking & writing.
