I started playing some work-league softball and made a fielding gaff at CF, which inspired me to write this fun piece perthirtysix.com/how-the-heck... Pretty cool how much literature is out there on this, starting with Vannevar Bush all the way to cameras on dogs catching frisbees

How The Heck Do You Catch A Fly Ball? (An Interactive Exploration)

An interactive exploration of how outfielders (and dogs) catch fly balls: the gaze heuristic, optical acceleration, and why a ball hit directly at you is the hardest one in the sport to read.

So this is an awesome first. Someone made a chalk version of the 17-0 daily challenge. Thanks mooser! This is amazing

Google is asleep at the wheel with their MCPs. Like what is this? I'm not doing all that Such a massive opportunity since their adwords and analytics UIs are overly complicated. Sheets + docs feels like table stakes now. Opportunity afoot

AI tools now generate ~7 million songs a day. And most listeners can't tell which is which, myself included. Five years into PerThirtySix, this is my favorite page on the site. @shrikhalpada.dev on whether music is just sound, from an incredible musician himself perthirtysix.com/is-music-jus...

really cool shoutout from The Guardian on my How The Heck piece (thanks @joshnicholas.com!)

🏆 JONNY B, whoever you may be, you're the first to complete the 17-0 Perfect Run challenge! Thanks for playing!

Are you taking LT + Ozzie Newsome or Jim Brown + Kellen Winslow? perthirtysix.com/nfl/17-0

The game I released 36 hours ago has been played more than 50,000 times. It's called "NFL 17-0". The premise is simple, based on NBA 82-0, where you try to assemble a perfect roster. These are the game-design decisions I think make all the difference:

Can't catch @shrikhalpada.dev at the top

Steph Curry made an absurd 44% from beyond 30 feet in 2015. So no one was really surprised when he hit this game winner from 38 feet. And that makes it all the more impressive. A short write up on game winners and what information theory tells us about the Steph perthirtysix.com/essay/curry-...

this guy is one of my favorite interactive visuals I've ever built :D (from the latest How The Heck piece, about solar panels: perthirtysix.com/how-the-heck...)

Across every NFL trade since 2006, the trade-down side wins the best-player comparison 45% of the time, the trade-up side 35%. It seems like Buffalo cracked this code. The Bills did three first-round trade-backs in 2026 (26→28→31→35) picking up two extra fourth-rounders and moving up in the 3rd.

The 12 best NFL draft classes in the last 20 years: The Seahawks 2010 (#11), 2011 (#8), and 2012 (#5) drafts were insane. Landing Russell Wilson, Bobby Wagner, Richard Sherman, Earl Thomas, Kam Chancellor, Golden Tate, and Russell Okung. Transforming them from mediocre to a juggernaut in the NFC

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...
