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.

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.

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.

We are running the above pi tests with an extra (Gradle based) build plugin so that it only runs mutations for the changed lines in that pull request. That drastically reduces runtime and still ensures that new code is covered to the mutation test level we want. Maybe something similar can be done for C or C++ projects.

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.
