Hi folks 👋
I haven’t started a new social in like a decade. How does this work again?
Right now I’m 3 chapters from finishing a book manuscript, and recently started a high intensity rocketship job. Saw a prancing unicorn and jumped on
Mostly posting in-progress ideas from the book.

Got @swizec.com 's new book, and dang, the bit describing standup hell, and PR drudge is extremely triggering.
So far, I'm really enjoying the read. It's quick, to the point, and educational!

People say AI will replace all the jobs shortly and the quality of output is shockingly amazing.
Until you ask “what about your job?”
Oh no it could never do that. Too nuanced and complex. I tried it last week and AI made a decently okay first draft that was almost useful.

"joins are slow" is like the worst myth bigtech propagated. the awful awful things I've built in my early days because I read one or two blogs about slow joins ...
*obviously* doing the join + filter in PHP is faster than using the database -.-
