Some reviews:
  • the keyboard is kind of crap. Notably the key "a" is very hard to press!!
  • the lack of a sleep state indication LED and "I'm powering on LED" compared to Lenovo is really sad
  • it gets way too hot doing work (Monero bootstrap) with lid closed, likely brought system down

It must have taken about one week running full time to sync the Monero blockchain which at the time was at about 3.1M blocks! I checked on system explorer, and CPU and internet usage was never maxed out, suggesting simply slow network. But the computer still overheated quite a bit and froze a few times.
The only cases where formal proof of theorems seem to have had actual mathematical value is for theorems that require checking a very large number of case, so much so that no human can be fully certain that no mistakes were made. Some examples:
If you ask for something, and they don't want to do it for whatever reason, they won't say no. They will say "I could do it, sure, no problem" and just never do it, nor explain why they don't want to do it!
And then if you don't understand that this actually meant "no" and push things further, they might eventually say "no", but they might become offended that you didn't understand them at first!
Please just say at least "yes" or "no". And if you're feeling specially nice, say "why no" which helps a lot the asker sometimes, though that's optional since people are entitled to their privacy. Just don't waste our poor foreigners' time with "bhlarmeh"!
Perhaps East Asia is a similar and more severe case of the same problem. But at least in their case it is so obvious that you already expect it.
The polar opposite apparently being Germans and the like.
Why we can't find more bibliography on this?

How I Faked Being American interview with Jack Barsky
. Source. The former East German spy undercover in the USA says:
I had learned to speak English and write it as well as anybody, but I hadn't become an American culturally.
My behavior was still very German.
Having now learned the difference between the German style and the American style, I have been trying to adjust and soften the way I'm approaching things.
Germans are in your face, they will tell you what they think even if you don't ask for it, and they will criticize you at any chance they get.
And that was me.
And there's still a residue of that left.
Americans will be a little more passive, sometimes passive aggressive, and they wrap everything, every piece of bad news, in some kind of a velvet cloth so it doesn't hurt that much.

Cryptocurrency swapper by Ciro Santilli 37 Updated 2025-07-16
A "Cryptocurrency swapper" is a service that swaps one type of cryptocurrency for another.
It is basically the same as buying and selling from exchanges for fiat, except that you only get fiat.
Swappers are in general able to receive send coins from any address, including self custody addresses.
Centralized swappers were a good way to workaround the endless Monero bans from exchanges circa 2024, e.g. x.com/cirosantilli/status/1771900725649371240 as they effectively serve as proxies for exchanges that are still legal in other countries.
They will eventually have to ban Monero of course, and then the only way left will be decentralized exchanges.
This leads to a scenario where the only effective way to ban Monero is to also ban all other cryptocurrencies. The question is if countries will go that far or not.
