When the star is sufficiently big, it will simply generate a smaller black hole at it’s center when collapsing, and the rest of the star mass that did not get included into the black hole will suddenly lose the structural support of the star core and will swing inwards and then outwards and form an accretion disk, because it’s impossible for all the outer mass to fall exactly at the center, there will always be some rotation and wobbling, and the black hole itself is very dense, so it will consume only as much mass as it’s cross-section. So that places the upper limit on the black hole size.

There is no clear theory on how supermassive black holes were created, supposedly the specific region of space just happened to contain a lot of smaller black holes right after Big Bang, and they did not get enough time to fly away and merged, and then slowly fed on gas clouds.

The stellar bodies like stars and black holes are also located very far away from each other and are very unlikely to ever meet, so two black holes colliding usually means that they have somehow traveled at sufficiently close distance from each other and got entangled, then they rotate each other for millions of years just bleeding their kinetic energy as gravitational waves, until finally they merge. So a black hole merging with another black hole is already an improbable event, but we are catching many such events because we are listening to the whole observable universe at the same time. And now imagine the chances of that merged black hole to bump into another black hole.

For the same reason the merged black hole is always rotating, it’s just impossible for two black holes to collide exactly center-to-center, any small offset means they will orbit each other, and near collision they will orbit each other really fast.

This is a single-component rocket fuel, which means the rocket will not explode in a huge slow-burning red fireball, but detonate like a nuclear explosion, minimal visual effects but maximum shockwave, and a mushroom cloud of vapor.

What’s the total human population again, 8 billion?

At least there are separate apps, and you don’t have to register your bank card with them to use maps, you don’t even need to enable GPS.

Definitely China. You go there, and you install the Baidu Maps app, because Google Maps does not work there. But it’s not just maps, it also includes chat, banking, public transport tickets, and voice calls, all in a single app. Many street vendors don’t even have cash, they accept Baidu payments through the app. And it’s as big-brother as it gets, it immediately asks for every permission and refuses to work otherwise.

Useless drama in the article.
Yeah, cheap cable and cheap charger won’t provide 35 watts of power. However that cheap 24-pin Type-C cable costs the same as 5-pin Micro-USB cable did in 2010, and you can use your old Type-A charger with it, so you’ll getting your 5 volts 2 amperes everywhere, and did I mention that the connector is reversible?

mcedit, because I’m not nerdy enough for vim.

Because you won’t determine the type of NAT during hole punching. This requires the client sending two UDP packets to two different IP addresses, then comparing their source addresses on the server.

Normally yes, you can just assume that two clients you are trying to connect both have port restricted cone NAT, and run the hole punching algorithm, and if the connection fails after ten seconds, show message to the users ‘Error 418: your router is a teapot’.

The one use case is running STUN/TURN server for NAT hole punching, that requires two separate servers, or one server with two IP addresses. You will only need that to run masterserver for games that support hole punching, or to run VoIP telephony / teleconference server.

Another use case is reliability, when your server is connected to several network providers, it will keep working if one of them has an outage, and will naturally have a different IP address for each network link. But your VPS does not have several network links, otherwise they would advertize that in bold red letters.

It depends on how rich you are. CEOs have their own, reduced edition of the law.

Some marketing survey shown that insignificant amount of users would use desktop mode, so they bought cheaper USB electronics for their next phone, that’s all. Never mind that Samsung adverises DeX so Galaxy users ar least know there is a desktop mode in their phone.

Robotized armies are already here, and they look nothing like steel skeleton humanoid Terminators, they are more like cheapest four propeller drones with an anti-tank mine strapped with zip ties, naked wires with no cover, because it’s single use.

Yes, Android is a (extremely heavily forked) Linux distribution.

Well ackshually Android kernel nowadays is built from an upstream unmolested Linux kernel sources, straight from Torvalds’ git repository.

And the rest is just the init system, which is not systemd so it’s better by definition even though it’s written in Java, and a display server written in Java, because there was no Wayland when Android development started.
