Wait, the police held your passport? Why?

If you're an American and you rent an apartment, the local police keep your passport until you leave. You keep a xerox. That's how it was at the time. I don't know if that's still the case. I didn't feel good about it when I found out (actually, the moment I signed the lease), but there was nothing I could do about it. My exit from Vietnam was almost humorous. I had about 50 DVDs in my suitcase, mostly encrypted back…

So how do you travel outside the country then, if the police are holding your passport?

It's extremely intuitive. You're trying to filter unusual, encrypted traffic. First rule exploits the IND-CPA property of most encryption. You want to kill traffic that has about 4 bits set to 1 per byte, i.e. traffic that "looks random". The following rules are exemptions for permissible encrypted or compressed traffic (note that compression, while not IND-CPA, results in high entropy and thus will trigger the first…

Cool, I'll just base32 my encrypted traffic and sail through!

Yep, or simply add "GET " in front of it. Best add it in front of all packets.

Using the same logics, one could say that:

- 'nice' means 'ignorant', - 'to travel' means 'to suffer torture',

and a lot of other interesting (but incorrect) ideas about what words mean.

Israel no longer gives you any visa stamps in passport. https://www.touristisrael.com/the-israeli-passport-stamp/974...

I visited Israel circa 2012 and this was true even then.

It used to depend on where you were coming from. When travelling to Israel for work a few years back, my passport (irish citizen) was not stamped, but my colleague's (at the time, a Turkish citizen) was.

She did commit a crime by travelling to Russia with an illegal substance, for which she got roughly the same sentence as a typical Russian would get if caught with a similar amount of drugs. This case doesn't seem to be out of the ordinary, except for the "criminal" being a famous foreigner.

Half of 20-year-olds in StP and Moscow would be in prison if that was true. Her arrest and imprisonment was entirely political.

They took your DVDs? On what pretext? Did you get them back?

I'm not sure what logic you're referring to, I'm simply stating the etymology of the word and other words in its family.

Not the person you're responding to, but it is an accurate description of genocide under its current meaning as defined by the UN (probably the most authoritative body on this kind of matter). https://www.un.org/en/genocideprevention/genocide.shtml What the Chinese are doing there is covered under Article II, c. If you are being pedantic by holding fast to the literal Greek translation of "geno" and "cide" then, well…

There is no authoritative body on the definitions of words. More generally, if genocide can mean "not killling, but very bad" then it is not much use except as an epithet - a negatively-loaded bomb to be lobbed in partisan debates at people who you think are doing something very bad. Virtually every controversial policy could be described as, "Causing serious bodily or mental harm to" some group.

> There is no authoritative body on the definitions of words.

false: there are a few. They aren't always correct, but they're more correct than you personally

> More generally, if genocide can mean...

there is no question what it means, you simply personally disagree with it

and since you definitely aren't an authoritative body on the definition of words, your personal pedantic insistence that the word mean only what the strict etymological roots imply, rather than how people actually use it, is irrelevant

> a negatively-loaded bomb to be lobbed in partisan debates

it's quite telling that you seem to view usage of the term "cultural genocide" to refer to cultural genocide as a bigger issue than actual cultural genocide

don't like people using the correct term to refer to the action? maybe get those perpetrating the action to stop, instead of telling everyone we're using the wrong words to describe it.
