Carioca··on Framework's 10G Ethernet module exposes USB-C's complexity
> The point of the "x2" modes is that they use the second pair of lanes that would otherwise go unused.

Thank you for answering a question I didn't know I had

Carioca··on U.S. science is in chaos
While this is a good long-term heuristic, I'd describe the upper rungs of government as more cynical on matters of science and theology than a typical fundie.

The only relevant difference is that you might be able to push it back a bit on "strategic interest" types of arguments

Carioca··on U.S. science is in chaos
For a country that has been a "brain magnet" for a good century, a "brain drain" might just be "talented people from wherever choosing to go somewhere else".

Case in point: an EE I know who is finishing his master's[1] is considering interesting proposals from solid (but not top tier, think Texas not Massachusetts) universities from the US, Germany and China. While he's afraid of the culture gap with China, it's clearly the one that has the more interesting things going on technically and the one he feels more excited about

[1]Engineering by itself is a bachelor's level degree here

Carioca··on WH proposes rules giving political appointees final approval on research grants
A friend in a prestigious European university said that applications were up in basically all fields
Carioca··on NPR finds "no sign" of Polymarket at its Panama HQ address
> Why would this be news?

Mostly because international litigation is, let's say, fraught issues (as in "good luck!")

Carioca··on It's time to reclaim the word "Palantir" for JRR Tolkien
I mean, could be accurate if they deliver the drones broken
Carioca··on Acetaminophen vs. ibuprofen
One weird analgesic/antipyretic is metamizole/dipyrone[1]. It's banned in the US and some of Western Europe (and prescription-only in other countries). Yet it's by far the most used medication here in Brazil and I have actually never heard of adverse effects, except some allergies

Carioca··on FFmpeg 8.1
Big difference for ffmpeg especially (but I imagine for curl too): it's not just one guy in Nebraska. Seems to have a very healthy community of devs involved in it.
Carioca··on What's Hiding Inside Haribo's Power Bank and Headphones?
Yup! And their whole social media “thing” is doing these kinds of on-topic analysis of (mostly consumer) devices
Carioca··on Why Does the U.S. Always Run a Trade Deficit?
> USG has not deleted and re-issued their USD even once so far afaik. Other countries do it more often.

Interesting side note: they did it once, just after the ratification of the US Constitution. The Revolutionary War was funded in some sense by devaluing the Continental Currency of the time, denominated in "Dollars". You could argue that the "US Dollar" only came to being with the coinage act of 1792, but as a Brazilian I'd say "Potay-to, Potah-to"

Carioca··on Students invent quieter leaf blower
Also never seen one here in Brazil FWIW
Carioca··on Why don't grocery stores stock pawpaw fruit?
And beyond pricing strategy, there are people who feel that a fair price is intrinsic to the product (e.g. the amount of work that goes into it). For example, it's pretty common in the classical guitar luthier world for there to be a decade-plus waiting list for some masters. They refuse to scale up their prices to “market-level” (i.e. a couple years max, takes months to build a guitar), because they don't want the guitars going to someone for purely economic reasons. Mind you, these are still very expensive, five figure instruments.

(edit: you could obviously think of it as a strategy that maximizes some other utility function in which profit is just one parameter)

Carioca··on UK 2022 rail station flow images
As agoose77 said on another comment, Github probably disabled the whole LFS (Large File Storage) for that repo
Carioca··on UK 2022 rail station flow images
I'm pretty sure Github disabled image downloads for that repo in the last few minutes.
Carioca··on Hyphens, minus, and dashes in Debian man pages
While I agree with most of what you've said, I'm not sure I see a use-case for the distinction between Hyphen, Minus and Hyphen-Minus. Specifically, with having all three. If I were designing Unicode, I'd remove the Minus sign specifically. That way, if you absolutely need to e.g. use an old font that used long minuses (in old texts they could be even an em-dash), it would still be _encoded_ as the parseable expected by every software to date
Carioca··on Apple CPU Architecture Through the Ages
There are a few answers to my question now, if you're still curious
Carioca··on Apple CPU Architecture Through the Ages
> such as the (in)famous evaluate polynomial instruction, POLY.

What CPU has this instruction and where can I learn more about it?

Carioca··on Small business owners say they're pressured to hire off-duty cops for security
As a Brazilian, I'm here to tell you: that's how it starts. If this isn't curbed, you'll have a presidential candidate thoroughly linked with them in ~20 years
Carioca··on Raku: A language for gremlins
I kept reading the post and had a growing feeling of “oh my god, it's like Perl but MORE.” Only when I got to the end I saw the footnote that it's indeed Perl 6
Carioca··on Sao Paulo: A city with no outdoor advertisements (2013)
Having lived in São Paulo most of my life, I'd like to corroborate this. The groups tagging buildings generally have nothing to do with (other) crimes. The only unsettling part was the time I saw that that the wall below my 6th floor bedroom window had been tagged overnight
Carioca··on Color Photos of Stalin-Era Soviet Union Taken by a US diplomat
The choice of bananas as a benchmark seems really bad given that the US invaded and supported coups throughout Latin America specifically to keep the price of bananas low.

> The idea that US and USSR were equals or even anything near it is totally absurd

That's not what I said. I said the material conditions of the population improved markedly more in the USSR than here in Latin America following WW2

Carioca··on Color Photos of Stalin-Era Soviet Union Taken by a US diplomat
I've been reading up on Soviet Rocket history and both Kurolev and Glushko were sent to Gulags for suspicion of organizing against the government. On the other hand they did do dome engineering work while there, so I suppose there were facilities that didn't conform to today's image of a Gulag
Carioca··on Color Photos of Stalin-Era Soviet Union Taken by a US diplomat
On the scale that the CIA said the average citizen of the USSR ate better than their counterpart in the US[1], while still having a lot of science and engineering going on. Material conditions in the USSR improved dramatically after WW2. A lot more than, say, here in Brazil, where we never had a communist regime though we did have a US-backed dictatorship

Nitpick: Pix is free between people. Companies pay ~1% of the transaction
Carioca··on The myth of the $600 hammer (1998)
The first version I heard went through a long diatribe on how “the US” (implying NASA) spent a long time and a million dollars creating a pen that would work in space and the punchline was “Well, the Soviets just used a pencil”.

Glad to see that this version has been losing ground to better retellings. If you check the Wiki article[1], the urban legend is mentioned

Carioca··on The myth of the $600 hammer (1998)
Reminds me a lot of the million-dollar space pen vs pencil story
Carioca··on Beans are protein-rich and sustainable. Why doesn’t the US eat more of them?
Put the two together and have a feijoada
Carioca··on Make up a guy
It's all fun and games until the chat-responder inadvertently buys the product. And when/if you reveal the deception, the other company sues. In AI court, obviously, where it will be decided by an AI judge
Carioca··on Should billboard advertising be banned?
We did it in São Paulo, Brazil a long time (15 years?) ago. It was a relief and I'm always a bit bothered when I'm on cities that allow it. It might be the case that some places in some cities should still keep it, but otherwise I'm still all for it
Carioca··on Brazil’s cars have run on ‘green fuel’ for a century, but not without costs
This is sugarcane ethanol and it is way more efficient than corn ethanol
