Back when [1] it was fashionable to advocate FOSS as ideology [2], we were thinking about tons of FOSS adversaries and how to protect from them - some real, some imaginary. The death of FOSS would come from big closed-source vendors, or from regulators (lobbied or just ignorant), from whatever.

We never envisioned that the actual FOSS death spiral would come from progress itself, much more so from AI...

[1] Oh what fun did we have. One of us in the Greek FOSS community actually put RMS in jail. [2] Something that I think nobody except RMS ever seriously believed in.

I heard there's a country where they can even SWAT you out of existence with a simple phone call, but it sounds so outrageous this must be some evil communist dictatorship third-world place. I really don't remember.

Not just C++. Even C parsing is context-dependent because of typedef. Requires a bit of hackery to parse in a conventional LL/LARL/LR parser.

No, we aren't.

It was this exact part of the conversation that touched me negatively too. marsf expresses some very valid criticism that, instead of being publicly addressed, is being handled by "let's discuss it privately". This always means that they don't want to discuss, they just want to shut you down.

And how would they know if my cheese has holes, given that there is a non-zero probability that a random cut over a piece of cheese goes through no holes at all? They would have to make so many cuts that the cheese becomes grated. And grated cheese most definitely doesn't have holes!

Having experienced several of the cuisines rated by Taste Atlas, I would not trust a comma out of their reviews :P

Swiss cheese have holes so the swiss dwarfs can hide in them.

Of all the places I've been, Singapore.

They have a population of 6 to 7 million people in an area of 700 square kilometers, resulting in a population density of 8300 people / km^2. Substantially more than that if you account for the fact that a large percentage of the island is still tropical jungle.

Despite that fact, their city planning is so good with large open spaces everywhere interspersed with greenery, that you almost never feel claustrophobic. Even the so-called "hearland" neighbourhoods with rows after rows of high-rise residential HDB buildings are quite pleasant.

The most claustrophobic place I've been in Singapore are the few squares in the center of CBD filled with skyscrapers that almost obscure you the view of the sky.

They're warning everybody, not just Singaporeans. It's just that Singaporeans are the most likely to go travel abroad, have some fun, and then come back like nothing has happened. But if somebody inbound gets caught in a random drug test at the airport (they do that), he's going to be prosecuted just the same no matter their citizenship. There were several (in-)famous examples of this happening.

Singapore does exactly that, and they explicitly warn outbound Singaporean travelers that any drug use outside Singapore will be prosecuted as if it has happened in Singapore.

Nowadays the Indonesian law requires at least two words for the person's full name, and the full name is regarded as a single entity no matter how many words it contains. Older generations of Javanese, having only a single name, usually duplicate it - I have seen such duplicate names in official Indonesian documents.

Most (though not all) Greek surnames are also gendered. The common practice is to inherit your fathers surname, changing the gender if you're born female. For example, a quite common surname is Papadopoulos (masculine) / Papadopoulou (feminine). It was usually chopped into "Pappas" when Greek immigrants to US were passing through Ellis Island.

Till the '90s at least there was an unofficial convention of anglicizing our surnames using the masculine form, ending up with things like Eleni (Helen) Papadopoulos, which in Greek sounds like a grammatical monstrosity.

Other surnames were commonly mangled in weird ways - Nicholas Metropolis (of the Metropolis-Hastings algorithm) surname was Μητρόπουλος (Mitropoulos). Metropolis is quite near phonetically but grammatically makes no sense in Greek.

Geez, you left yourselves behind. We Greeks at some point decided that 3 /i/'s are just not enough for us, so we invented some diphthongs (ει, οι) also pronounced /i/ :D

Even the assumption that people have (something that can be used as) a last name is incorrect.

Currently I'm living in Indonesia, where a surprisingly large number of people have just one name (plus, when they have many, they're more often than not completely arbitrary).

This was very common practice up to the '90s. If you have a single name, they duplicate it in your passport, and you end up like "Soekarno Soekarno". Which STILL raises eyebrows in several western countries' ignorant airline employees (and sometime even immigration officers, though they're admittedly more well educated about such issues).

Nowadays they proactively give at least two names to their children to match the western(-ized) system assumptions.

Did you ever travel internationally along with only one of your parents? I know of many cases around the world where authorities will definitely cause you some trouble if you try to do that, even more if somehow "expected" naming conventions don't match up. At least that's how it's been in the last 2 decades.
