This one was satisfying. Spend today fiddling with force-directed layouts for my Hollywood graph. Each dot is an actor, connected to others via films they've been in together. Check it out: hollywood.six-degrees.app/explore

TIL you can set a limit for YouTube shorts - it's always pissed me off how some apps become doomscrollified, and I'm extremely susceptible. I set it to 0 🙏

I made something to generate blueprints for solves of my son's railcube, using every piece. How long until it finds a duplicate? (hint: it's at 2k an hasn't found one yet)

AI certs these days: "An SME is an AI skeptic. What's the most appropriate action to take?" 1. Call them a woke snowflake 2. Agree with them: AI is stupid 3. Do the middle finger wind up crank thing 4. Listen to them, show them quick-wins that will make their day-to-day easier

I'm gonna post soon about how I made a program to generate thousands of possible solutions for my son's railcube. It will involve using my js port of google or tools to solve real-time in the browser. It's very fun

One of my biggest pet peeves of appearing competent is that people will just send me links to tech stuff with no context. Why are you sending me this? What do you want me to do with this information? Can I just say "cool" and not read it?

I built an interactive guide on how Shazam (the music identification app) works! This is the next installment in my newly coined "How The Heck?" series, where we explore everyday tech that can feel like magic (QR Codes, GPS, and now this one). Hope you enjoy it! perthirtysix.com/how-the-heck...

I made a contexto.me solver. I was able to zero in on it using the GloVe 300d dataset. Uses lemmas under the hood (runs, run, runing -> run), and then "just" find the word(s) where the guess is X distance away. I think my best score before this was like 50.

I spent 2 months learning about quantization and am extremely proud of the post I've written about it. I think these are some of the nicest visuals I've ever made, and I love how this compression technique invented in 1898 is being used on the bleeding edge in 2026. ngrok.com/blog/quantiz...
