While not impossible, you have to try fairly hard to fuck up your phone like this. I’d be actively impressed if your story is true (particularly as you used the plural), and if so I’d like to know what they were specifically trying to install that fucked up their phones.

It’s just statistically more likely they downloaded a malicious app from the Play Store than had any chaos side loading.

No you fool! Don’t you see that because Wish exists buying from Best Buy is also a scam?!

Honestly I don’t get people like this. Are they trying to protect other people? I’ve never seen it framed that way, but it’s the only reasonable explanation.

Of course WeChat dominates china when they ban other apps from even operating. WhatsApp can’t operate there. Facebook is entirely banned in fact. Twitter is blocked as well.

Amazon failed to get a foothold due to complex regulations restricting them, which forces them to shut down their marketplace there.

So you can’t really compare that to a much freer market.

Except the point of this post is that a different sort with worse Big O could be faster with a small dataset.

The fact that you’re sorting those 64 ints billions of times simply doesn’t matter. The “slower” sort is still faster in practice.

That’s why it’s important to realize that Big O notation can be useless for small datasets. Because it can actually just be lying to you.

It’s actually mathematical. Take any equation:

y = x^2 + x

For large x the squared term dominates. The linear may as well not exists. It’s O(x^2). But when x is below 1? Well suddenly that linear term is the more important one! Below 1 it’s actually O(x) in practice.
