If anyone is following me here, I tend to prioritize updates on 🦋 nowadays. Twitter simply became unusable for my usage.

We somehow got put in the spotlight the last few days! First we'd like to thank the organizers of the AI show for that, we can't get enough of this stuff. I'll say a few things about where we are and what we do.

You owe 107,000 USD per person in federal debt. We owe close to nothing and have a huge surplus on both our trade balance and our government budget. Our standard of living is better in almost every way. We have no idea why you think that the US is so attractive for everybody.

Kinda easy to say when your ass isn't on the pan when "it doesn't pan out". The US were a segregated country only 60 years ago, and even today your "exceptionalism" means some of your citizens are unable to even vote.
Replying to @dhh
And letting US be US means doubling down on building, on progress, on optimism, on innovation, on pragmatism, and all the rest of it. I don't know if it's all going to pan out, but I'm excited to see a team with Musk, RFK, Vance, Vivek, and even Trump try.

Oh look, someone trying to be relevant again
Félicitations Président Donald Trump. Prêt à travailler ensemble comme nous avons su le faire durant quatre années. Avec vos convictions et avec les miennes. Avec respect et ambition. Pour plus de paix et de prospérité.

I probably should explain better; peer dependencies have a direct impact on how far hoisting algorithms are allowed to host packages. Without this annotation, we may generate hoisting trees that don't respect the proper dependency versions.

Chrome should deprecate the Ctrl+Shift+P = print shortcut and let webpages bind it to command menus🔥
