Any route from white to white visiting N white squares must visit exactly N-1 black squares. Any route from white to black visiting N white squares must visit exactly N black squares. Therefore on a board with an equal amount of white and black squares, it's not possible to walk a route from a white square to a white square and visit all squares.

You can prove it through induction. Starting with a route that visits just one white square, you visit zero black squares. Then, if you want to extend your route with one white square, you must also visit exactly one black square to get to it, as no two white squares border one another. Meaning for a route of S steps (where each 'step' is actually two moves from a white square to the next white square), you visit S+1 white squares and S black squares, or equivalently N white squares and N-1 black squares.

Almost always South Parks villains are portrayed in a heavily satirized way. A common thing they do is to portray those attacking eg an environmentalist as 'normal', but then overly exaggerate how 'true' the attacks are. It's to ridicule the attackers, not who they attack, by showing just how ridiculous this villain has to be for the attacks to make sense.

The historical pronunciation of this letter is irrelevant because it's a modern word with a modern pronunciation.

No, the current president is also called Ferdinand Marcos.

The k-sound is used when the chi is prefixed in front of certain vowels. The ch-sound is the truly correct pronunciation here, there's no history involved for that.

Knuth, the guy who coined it, also says the ch-sound is the correct one, though he also says the k-sound is also acceptable. As long as you do not use the ks-sound at least :)

This article is overly sensationalist/alarmist and doesn't match the study behind it.

This is the study they're referencing: https://www.mdpi.com/2076-328X/5/3/388

It primarily focuses on internet addiction and video game addiction. Pornography is mostly mentioned in passing as "likely similar".

In it, they review evidence that these things can be addictive, and that people experience pleasure doing them (this is the whole "same-areas-as-coke-and-meth" thing btw; the brain is happy playing video games, and it is also happy doing coke). However, they distinctly mention that behavioral addiction is not necessarily the same as substance addiction:

Together with studies on Internet addiction and Internet Gaming Disorder we see strong evidence for considering addictive Internet behaviors as behavioral addiction. Future research needs to address whether or not there are specific differences between substance and behavioral addiction

The exact quote about areas of the brain thing:

Georgiadis and Kringelbach concluded, “it is clear that the networks involved in human sexual behavior are remarkably similar to the networks involved in processing other rewards”

The brain rewards sexual behaviour. Makes perfect sense from an evolutionary point of view, so not exactly a shocking conclusion.

And regarding the "brain-altering" thing, the study also directly mentions that this is simply what happens when the brain is activated through its reward systems. This "altering" happens for everything that triggers some kind of dopamine hit. It's not the case that porn does something special here; a model train hobby for example would do the same to enthusiasts for example.

I remember this study actually, I've seen it before. It is frequently misquoted or represented in an extremely alarmist way, mostly by people with a dislike for pornography. But the study doesn't back up their assertions that porn is anything special when compared to any other behavioral addiction, it actually expressly doesn't.

It's also wrong, it's supposed to be a ch-sound as in Bach.

It's actually a ch-sound, as in Bach. But Knuth also thinks the k-pronunciation is fine.

Apparently the reason was to make these anti-corruption agencies more efficient. But Zelensky will now propose an additional bill to secure that no interference can happen.

I mean it's a valid concern. He's also nowhere near the first to voice it. I attended a presentation from a Microsoft exec who explained that Microsoft had already developed very powerful voice mimicking technology, well ahead of anything public at the time. It required only a few seconds of speech before it could fully replicate your voice. But their ethics board or whatever stopped them, due to the massive fraud risks. Nowadays I think they've adapted the tech to voice recognition used in Teams instead.

Of course, MS wasn't the only one working on this and other people have since published these solutions, so the cat's out of the bag now.

Polls have repeatedly shown that the Israeli population is majority supportive of their government's actions in Palestine.

"Porn" is extremely broad. There's plenty of perfectly ethical porn around. Most major producers have pretty strong standards these days. It's not the same industry as it was 10 years ago.

But in this specific case they went after a porn game, not featuring real people. There's basically no real harm here. People occasionally argue that porn addiction is a problem, but that's mostly an addiction problem, which goes for most addictions. The thing addicted too isn't the problem, it's the very nature of being addicted that's causing the issue.

It's fine of course to dislike porn, but to effectively ban people from producing and consuming it is an entirely different matter. That does seem like a massive encroachment on individual rights to me.
