The purpose of art was once not to shock or transgress, but to elevate the soul.

BREAKING: MIT just completed the first brain scan study of ChatGPT users & the results are terrifying.

Turns out, AI isn't making us more productive. It's making us cognitively bankrupt.

Here's what 4 months of data revealed:

(hint: we've been measuring productivity all wrong)

@penberg We're on the same boat. I buy books to have a nice bookshelf behind me and pretend I am a prolific reader

@AJamesMcCarthy Amazing Andrew. keep up the great job.

@eatonphil Although a degree is not strictly needed, I don't have one myself, I highly recommend going after one. Depth is very important but breadth is as important for filling gaps and helping you understand how things connect with one another. It's not easy to go for breadth in your own

@VictorTaelin Take care of yourself

@JohnKoepi the original report has much more details, might shed some light on the investigation process: https://t.co/nf9IT2mDi7

I fixed linux kernel to make scylladb test suite happy. It's a nice feeling to contribute to linux after so many years, since I switched from OS to DB realm: https://t.co/MwNxUcil9O

Patch was upstreamed.

@emaxerrno this triggered some good old memories of my childhood haha

@penberg I know a world class chemist who really believes people were riding dinosaurs in the ancient china.

[Raphael (Raph) Carvalho @raphael_scarv]

@penberg never thought of it this way haha this triggered some old memories of mine of a young Raphael hosting a mmorpg called tibia, and this was the first time I had contact with sqlite. the world map had its own format, but accounts, players, items, etc were all stored on sqlite.

[Raphael (Raph) Carvalho @raphael_scarv]

retsnoop tool works amazing, and helped me to find a regression in linux kernel, triggered by usage of io_uring + buffered writes in scylladb test suite. the fix will land soon; for further details: https://t.co/SZjsisyPLL

@paulg small correction: all of them live the same way, but that 1% (maybe 1% is an underestimation? the world doesn't have a small number of hypocrites, does it?!) judges you even though they do the same.
