Exactly the same in Japan; moreover, many e-commerce sites reject foreign credit cards, even those of international brands (Visa/MasterCard).

What I heard was that payment providers charge higher fees for allowing foreign cards, so website owners (who focus on domestic business anyways) just won't bother.

In Japan, eSIMs are exclusive to Japanese citizen and permanent residents. Not sure about the reason behind this but I don't think they're going to change policies just because Apple is pushing.

Card companies _do_ charge interest if you pay in (usually) 3 or more installments, unless explicitly mentioned being interest-free.

I once bought a TP-Link Wifi router as it was pretty high-speced at the time and people recommended it. I was happy with it until it hijacked my HTTP connection to tell me there's a firmware update. Will never consider their products again.

That depends on the modulus being divisible by 8, which is not always the case. A common example is modulus = 2^31 - 1 [0] which is prime.

The article claims that "it is indeed a uniform distribution" so I wanted to point it out.

1. You don't turn PRNG into "true" RNGs simply by picking seeds from environmental randomness. The seed is just the initial state, as long as the output is generated by a deterministic algorithm, by definition it's a PRNG. At the very best you can make a CSPRNG, but not a "true" RNG.

2. The dice roll example is not uniform distribution, I think this is a common pitfall when generating random integers of a range. `randomNumber % 6` results in a slight bias towards 0 and 1, since 2^31 % 6 == 2, there are more numbers in the range [0, 2^31-1] that map to 0 and 1 than those that map to 2...5. To make it uniform, for example, you should always discard if `randomNumber < 2` and regenerate another number for use.

But you're not forbidden from talking about what you mentioned, that's why you're posting here, no? Try to post anything about Tiananmen on any forum based in China. To me this is the key that makes CCP strictly worse than the US govt.

Firefox will eventually follow up as well:

"To continue to promote the use of HTTPS and properly convey the risks to users, Firefox will eventually display the struck-through lock icon for all pages that don’t use HTTPS, to make clear that they are not secure." [1]

I guess design patterns should never be applied. Those are simply optimal solutions to common design problems in OOP. When you encounter your own problem, derive your own optimal solution, and you call it some "pattern" if it happens to resemble one.

IMO pattern names are merely for communication purposes, like saying "abstract factory" instead of having to say "I have an interface F for creating instances of interface A, where different implementations of F can be chosen at runtime to create different instances of implementation of A". And also you are not required to call your factory "Factory".

I've been using WSL + wsltty [1] + Xming [2] for months and didn't encounter major issues. wsltty also added support to the Microsoft Store version recently.

For Xming, simply set DISPLAY in shell and local GUI programs just work, as well as SSH X forwarding.

Can't agree more that URL syntax is overcomplicated. Even existing URL parsing libraries behave inconsistently and lead to security vulnerabilities [0].
