one recent learning from wearing an oura ring is that I burn a decent number of calories when giving an academic talk. just one more incentive to get out there and promote your research, i guess

nosferatu feels like a supercut of diablo iv cutscenes (non-derogatory), right down to the fact that ralph ineson (the voice of lorath in diablo iv) has a big role in the movie

At the Drive In - One Armed Scissor (Live at David Letterman)
YouTube video by gusbucker At the Drive In - One Armed Scissor (Live at David Letterman)

saw the new documentary about omar rodriguez-lopez and cedric bixler-zavala last night.

1st, the doc is so good. 2nd, it includes footage from this 2000 ATDI performance of one armed scissor on letterman, which i had never seen before. it goes so hard!

the way the norcal earthquake caused a tsunami warning that then got canceled made me realize how cruel it was to shake your world, cause a wave of emotions, and then call things off. if you give me another shot, we can build a relationship with a strong foundation on solid ground. hope you’re well.

“this actually involves you in the news” is a good one-liner of that Twitter magic that has felt missing for a bit.

On top of this, probability of winning the challenges changes as a function of how many people are in the field. As N gets smaller, Kyle would’ve been more likely to win.

Despite this, I agree with Andy’s back of the envelope calculation and was also surprised it got so much pushback!

1) having the guy who played Russ Hanneman record an announcement video on cameo when I accepted my job at Berkeley

2) tweeting about my stay in a London Airbnb that was basically a bathroom with a bed in it (link below):

OK, one of my favorite things about X/twitter was the survivor community, so I’ve done the public service of putting together a #Survivor starter pack.

Still very much a WIP - please reply with accounts I should add!
