What the hell do you mean, "One typo slipped into the commit message", and how do you typo a Chinese character?
I promise Anthropic I'm not coming for your crown with this 20 million param chess prediction model. You don't have to sabotage my "research" with this nerfed Fable

Yes, the United States has the most progressive tax system in the world. The top 1% pay 40% of taxes, the bottom 50% pay 3% of taxes. We can make it even more progressive by zeroing out taxes on the bottom half. It’s a small amount of the total tax revenue but very meaningful to people in this group.

Jeff Bezos said the bottom half of Americans should pay zero federal income tax.
He cited a nurse in Queens making ~$75K and paying ~$12K in taxes saying “we shouldn’t be asking this nurse in Queens to send money to Washington.”

I've never been more thoroughly owned than when I ordered a shake in the company Doordash order, it exploded over the other items in-transit, and @delk called it a highly asymmetric downside play
8yo [to 5yo precariously balancing her cup on her plate]:
"That's literally asymmetric downside. Like dad talks about."

Don't worry, you're not bad at chess. You're actually bad at everything. Chess is just one of the only things with a good rating system.

Decades of Clean Code obsession has poisoned AI training
When you say "simplify this", they hear "move this stuff around to other places"
Guaranteed net-positive lines of code via any AI "simplification"

95% of X ads engagement is fake, because advertising posts react on tap start instead of tap end, so they accidentally activate all the time while trying to scroll your feed.
This is both terrible for users (me), and advertisers (also me) @nikitabier

This "Horizon Beta" model is sort of GOATed. I gave it a prompt to figure out a non-negative loss function for a gamma distribution head, to prevent gradient interference, and it nailed it.
Sonnet, Grok, Qwen3 275B, Kimi K2 had all fallen flat on their face on the same task

Solid is by far the most sensible thing to build your web app in.
The mild discomfort of creating signals absolutely pales in comparison to the endless grind of dependency arrays and unnecessary rerenders.
I will die on this hill. The hook emperor has no clothes.

A story in two parts. How does a project as big as React Native not have a way to profile release builds.
I cannot tell you how many times I have a large issue with React Native, only to find an open issue from 4 years ago with no activity
