It's way more likely the Supreme Court judges have him under their heels like the cockroach he is.

(+) where he'd have Milei's full support. I still believe our Supreme Court and Federal Police wouldn't be that dumb (although they snoozed and many of the Jan 8th vandals fled to Argentina). Fingers crossed, I sincerely hope he rots in jail.

So do I. But some snakes are plain dumb, which he heartily was. He played escape cards twice: once, fleeing to the US before ending his mandate, second, hiding in the Hungarian embassy during a paranoid surge fearing being arrested. It'll be shameful if he manages to flee through Argentina, (+)

I don't believe so. He attempted a coup (don't forget our history, we were through a 20 year bloody military dictatorship that started with a coup) and is politically much weaker. He pulled a tug of war with the Supreme Court, but he's far, INFINITELY far from being Donald Trump.

More Brazilians are acutely aware of Biden's "reverse 64" (love the expression) than you'd think. Yes, it's uncomfortable, but this has been brought up quite a few times even in the mainstream media. You're correct, however; when he's arrested, this probably won't be even vaguely remembered.

Also: his passport has been seized months ago, soon after he returned. He won't enter the US unless Trump will let an illegal alien willingly 😈

Not yet. The due legal process in Brazil is long and slow. He'll probably be arrested in nine to ten months - unless he attempts to flee (but his passport has been confiscated).

He already did when his mandate ended. He returned, probably for fear of burning all his money (the exchange rate was 1 USD = 5 BRL; also, although he had more than 1M USD, he's a scrooge and still delusional about returning to power). The Federal Police are probably monitoring him. No escape 🤞🏻🤞🏻🤞🏻🤞🏻🤞🏻🤞🏻

Yes, we can! (This topic is the only politics you'll see from me here - but boy, are the champagne and Orval already chilling in my fridge...)

We should do things because we believe they're right, not because lots will also do it. Just picture those who did it before it was popular! If you keep doing it, you'll be making the same difference as before but, in times like these, that small difference will be a much bigger one, in a sense.

Thanks!

Would you know where this was published?

Not a typo. Perfect Spanish/Portuguese spelling (pick your favorite).

Sorry for the imprecision about the license fee!

Hope they release it for Plus subscribers soon. How did you prompt it to get ideas?

Oh, I'm older. I ran Windows 95 on a 386...

Wouldn't that be awesome 😎

I found a Siesta benchmark in their homepage: siesta-project.org/siesta/bench...

FHI-Aims is paid but there's a possibility of them waiving it.

There are also CP2K, which uses pw for valence electrons and localized basis sets for core electrons, and runs on GPUs, and Crystal. They're paid, however, and I've never used them (yet).

(open-source) codes with localized basis sets that come to my mind: Siesta and FHI-Aims. FHI-Aims comes with a set of optimized basis sets for all elements of the periodic table (they call it Tier-1, 2, 3, differing in the number of basis functions, I think). Siesta is free for academia, (+)

didn't extend far enough to properly describe the interaction with the surface. I also remember having had a lot of trouble optimizing a basis set when there were no tools available to do it. I implemented my own solution at the time, but the result wasn't so good.

Currently there are two main(+)

I used Siesta for about 20 years. Never did a benchmark, though. I suppose it shouldn't be difficult to find one. The main difficulty is to get a really good basis set. For example, I remember a paper where the Siesta developers commented on a result for polymer adsorption because the basis set (+)

Congrats!

Seriously thinking about entering this field with a more physical approach, without leaving quantum chemistry aside. #CompChemSky

You definitely should. I hope that, if you do, you'll finally be able to enjoy it! It's a place that, despite its problems, is worth visiting.

I'm so sorry to hear that. Good riddance, then.

What a gorgeous photo of Urca! Hope you had a good time in Rio.

Energy barriers for catalytic processes. I'm so glad my current collaborators are swedes and Brazilians with a position in Belgium...
