25 years ago today Welles Crowther gave his life helping others on 9/11. This is the best story @espn has ever done. Share it with your kids and any others who may not have been alive on 9/11 and don’t know what true bravery in the face of evil is.

"Was the hitter not on time or not on plane?" 😂 @CraigStem breaks down how you should be reading swings on the mound and how to leverage a whiff. 📝

Once upon a time, there was a CS AB AP exam that was the equivalent of two semesters of freshman CS. It was killed in 2009, leaving CS A, where high school students take a full year to cover one semester of material. TIL that in 2025 they dumbed it down further and removed polymorphism entirely. I'm cheering for @tracewoodgrains and @educprogress but man if you want your kids to be challenged you probably just need to home school somehow, it's like America is now terrified of demanding anything from the children it's nominally educating.

On the left, you can see child autism diagnoses. On the right, you can see states with policies that give schools more money when their students are diagnosed with autism. When these policies pass, autism diagnoses increase by almost 25% in one year!

Fuzz testing is an absolute must for any database (or any sophisticated system/program whatsoever). Trying to compose the edge-cases manually is tedious, hard to review, and is likely to still live a lot uncovered. Randomised tests are easier to develop, maintain and run.

If you step on the mound and you don't believe you're at least a little bit invincible, then your physical/mental preparation probably wasn't good enough.

The next throwing arm that gets “flushed” after a high-pitch outing by running, will be the first in history.

When MLB expands to 32 teams, it should forget the AL and NL. Embrace a dramatic geographic realignment. Here's one way @JimBowdenGM thinks it could look ⤵️

If you think it’s weird that your kids watch YouTube videos of other people playing Minecraft, just remember you watched a TV show about other people reading books.

Whether you’re an 8 year old with great mechanics or an MLB pitcher throwing upper 90s in a bullpen, somebody will always find something negative to say. Nothing you do will ever be good enough. Eat Arbys.
