A plot here would go a long way.

roberto··on Facebook reveals its cryptocurrency Libra
> Is HN really more anti-Facebook than the general population?

Yes, definitely.

> If so, why?

Because the general population cares less about privacy than HN. But I (not OP) think it goes deeper than that, and I've seen people here deliberately spreading lies about FB.

roberto··on Milankovitch Cycles
I have a friend who did his PhD studying Milankovitch cycles in the Netherlands.

When he defended his thesis, his friends presented him with the "milankofiets": a bicycle ("fiets", in Dutch) where the wheels were off-center, and the crown was elliptical (and also off-center). Biking it was very hard, and the speed would vary depending on the phase of each part of the bicycle.

roberto··on Foreign Minister Taro Kono to ask media to switch order of Japanese names
Not necessarily. My last name is Ferreira De Almeida. "Ferreira" comes from my mother, and "De Almeida", with space, comes from my father.

roberto··on 93% of Paint Splatters Are Valid Perl Programs
The name "Ruby" is also a play on "Perl" ("pearl").
roberto··on The Mystery of Time’s Arrow
What if time's arrow can be reverted, and is being reverted all the time, but we don't notice it because, just like and omelet would become an egg, our brain state would revert to a previous one?

As far as we know time could be running in reverse, but the process in our brains would make us feel like it flowing forward. The book "Permutation City" explores this idea, albeit in simulated brains.

roberto··on Brazil waives visas for visitors from U.S., Canada, Australia, Japan
> At the same time, the aforementioned party gave billions of dollars in infrastructure projects throughout Latin America bolivarian states, that without a doubt won't make returns in any way.

First and foremost, the money went to Brazilian companies that built that infrastructure.

Second, it was a loan that has to be paid back by those governments.

Third, the loan is covered by insurance.

2^225 < 52!
roberto··on Boardgame.io: State management and more for turn-based games
Seems like if you click on an already marked square it still counts as a turn, so if you double click you get this behavior.
roberto··on What if other professions hired like software development?
Exactly! I used to be a climate scientist, and wrote open source libraries on my free time. I now work as a software engineer, and I love my job. But on my free time I now make music.
