I'm sorry. How do you expect a jet flying to get even close enough to a satellite to accelerate a missile to it?

Highest ever flow fixed wing "aircraft" is SpaceShipOne with rocket engines. Well above what a typical fighter jet might do: 112km height at 910m/s And a typical rocket will go what? Mach 2 or 3? So let's say Mach 4 at 112 km, which is 1096 m/s

A typical Starlink orbit is either around 340km height or more typical 550km at either 7726 m/s or 7613 m/s at the different heights.

That gives a minimum distance traveled of at least 228km and a speed gap of 6630 m/s or 23868 km/h that the missile still needs to close.

There are probably ways that Brazil could try and destroy satellites if they want to. But launching missiles from (rocket powered) jets definitely isn't one of them.

How is it nonsense?

The EU law is that the reject all should be exactly as easy as the accept all button. 1 extra click, however minor of an inconvenience it is, is extra effort. And therefore strictly speaking in violation of the law.

Nothing will ever happen but it's valid criticism.

It's just a guy talking 99% of the time and the few visuals that are in the movie are not required to understand the story. I'd just listen to it like a podcast. The guys voice and pronunciation probably beats text to speech from a blogpost with images.

But MS had nothing to do with both the testing and rollout?

It's a broken 3rd party component. Croudstrikes testing and rollout procedures were inadequate.

It is not, but a write amplification of 36704:1 is one hell of an exploitable surface.

With that same Raspberry Pi and a single 1gbit connection you could also do 333333 post requests of 3 KB in a single second made on fake accounts with preferably a fake follower on a lot of fediverse instances. That would result in those fediverse servers theoretically requesting 333333 * 114MB = ~38Gigabyte/s. At least for as long as you can keep posting new posts for a few minutes and the servers hosting still have bandwidth. DDosing with a 'botnet' of fediverse servers/accounts made easy!

I'm actually surprised it hasn't been tried yet now that I think about it...

There are inverters that support battery backup, recharging from solar and grid power that are supposed to go between your grid tie-in and the rest of your house. Quite a ways more expensive, but the battery capacity is probably relatively cheap compared to UPS power and is essentially a backup for your entire house.

The one I read about a while ago was a Growatt that is basically an all in one box. Can provide power from batteries, recharge from solar or grid power, feed back excess solar power to the grid, etc, you name it. And I can imagine other brands producing the same solution.

I'm lucky enough to live in a country with almost no power cuts though. I think we have at most 1 a year for max 10 minutes. So can't say I have any experience with it myself.

That is not the correct analogy. Offcourse you can customize it. Just like you can customize or mod the game.

But you won't get the actual designs to the bicycle. You will not get the blueprints to send to a factory to create exact duplicates or with your modifications.

The biggest red flag is probably that they claim to just be the WireMin protocol, but haven't published any protocol specifications. In the spirit of open and unmoderated communication I would hope they would at least publish their protocol specifications, even if they won't opensource their own client for it.

Releasing the source code would allow anyone to copy AND modify or extend the game as they see fit. Including all the inner logic that is normally compiled away.

Piracy or a compiled release without DRM (like GOG) only allows you to play the game and maybe modify some parts of it through modding after a significant amount of effort.

Honestly the default config is good enough to prevent brute force attacks on ssh. Just installing it and forgetting about it is a definite option.

I think the default block time is 10 minutes after 5 failed login attempts in 10 minutes. Not enough to ever be in your way but enough to fustrate any automated attacks. And it's got default config for a ton of services by default. Check your /etc/fail2ban/jail.conf for an overview.

I see that a recidive filter that bans repeat offenders for a week after 10 fail2ban bans in one day is also default now. So I'd say that the results are perfect unless you have some exotic or own service you need fail2ban for.

There is also a much more in depth blogpost by Stephen Wolfram about his work for this movie. I don't think it goes much more in depth on the language aspect but he tells a lot more about the process and questions he got from the movie creators.

Exactly. They are being transparant, it looks like it will be an opt-in when the time comes and are already telling you why they are collecting data. Now if they will tell you exactly what data they will be collecting in a short way before asking approval this is a textbook example of how analytics data collection should be done.
