Man she was hard to get. Helped fight off an invasion on a space station, had to save an ice planet from destruction, and helped find a wanted criminal in Space China. My friend commented that this was harder than getting a gf 🫡

Ask any statistician and they'll know 1.96 as the z-score for a 95% threshold. Ask any gacha gambler how many pulls they're gonna need for their 5 star if each pull has roughly 1% chance and they'll say 75 pulls

I love it when I’m lying in bed and I suddenly think up a potential bug in my job so I get up and write a PR at 3am to fix it

Feels good ubering from chinatown after my haircut to the office on FDR Drive. Nice views, window open, music in my ears.

Just hit a cryotherapy session and I felt like a smoker, wanting to cough after every inhale and blowing out the steam. Then a massage chair to follow it up, the best recovery I’ve experienced so far

My gamer brain hears “good luck have fun” whenever I see glTF 😭 also why tf is the magic number in a glb file literally just glTF in ASCII representation

Today I learned a new important lesson, slow code is a natural rate limiter. A job was too slow and OOMed, I was told to speed it up. I improved it so it could do ~60x more work. Accordingly, on its first day in prod it took down a downstream service cuz it was too efficient

The real problem of humanity is the following: We have Paleolithic emotions, medieval institutions and godlike technology. And it is terrifically dangerous, and it is now approaching a point of crisis overall. - Edward O Wilson

I work with bits a lot in my day to day job right now because I’m handling in memory indexes for a database. This reminds me of an optimization roaringbitmaps does to handle memory efficient bitsets
