Honored to play a small part in making this episode!
Thanks to @michaelhobbes.bsky.social for reaching out to me. My job was mostly starting to write down "he should also talk about this study" and then said study getting mentioned before I finished writing

I feel like I say this every year but I really need people to hear it. Halloween is the best American holiday. Just kids outside welcomed into their world, marching around together, showing off their costumes to the elderly, parents meeting parents, neighbors catching up with neighbors.

Happy Halloween! My algorithm is haunting me by serving videos of someone trying to build an ML model with 100% accuracy. Time to go celebrate my friend's spooky birthday and do zero math

Made a small React app with Typescript so friends could do a scavenger hunt during our Halloween party!
Main request was for a more extensive + harder hunt, which I'll take as a win. Time to level up my front-end game before next year!

This is a good example of why I yell at people for sharing poll results as screenshots/text without linking back to the actual poll toplines. It breaks the chain of information and makes it way easier for bad actors to thrive.
This ME-Sen poll and this account are fake. No such poll on Emerson Polling's website or X feed. And take a close look at the account's handle: @PoliticPollss when the real one it's impersonating is @Politics_Polls.

I'm proud of the knowledge I've cultivated in social science methods and more tech-y stuff. This combination also threatens to make me one of the most annoying people in the world
The superpower of books like Sapiens is that they require expertise in like 12 academic fields to debunk. So you get these super detailed takedowns of small sections that look to laypeople like nitpicking.

My favorite part about this is the camera work. Absolutely no idea where the ball is, like a guy with a flip phone trying to take a picture of Mars.

In a first, renewables generate more power than coal globally
In a first, renewables generate more power than coal globally
Solar and wind power aren’t just keeping up with global electricity demand anymore – they’re pulling ahead. According to a new analysis from energy think tank Ember, solar and wind combined outpaced global electricity demand growth in the first half of 2025. That shift led to a drop in both coal and gas generation compared to the same period last year. For the first time ever, renewables generated more power than coal globally.

One of the most powerful skills you get with more and more experience is just understanding what you can ignore lol.

Also, Twitter and Bluesky helped me get every single job I've had since 2019. Being (perhaps too) online has been more professionally useful than I ever would have imagined
