What you might be referring to is the question whether you’d like to import the GPG key for that repository. That happens when you first install a package from that repository. Could that be the one? I’m not aware of any other prompts.

It is, though. Safari has native support for 3rd party adblockers, it’s just that many people don’t know. AdGuard is one of the good options. Safari is doing the actual blocking for the most part (the extension just hands over the filterlists), but nowadays some of the adblockers include an optional extension that applies some rules for complex ads that are not supported by the Apple API, such as on YouTube. As an end user you just have to install and enable the adblocker.

Then there are also other browsers available with built-in adblockers. Admittedly those are all limited in some ways because they’re forced to use the same browser engine (outside of the EU), but they are very effective at blocking ads.

It’s Markdown syntax. You can actually format it nicely in a code block:

bool isEven( long long x ) {
  if ( x < 0 ) x = -x;
  if ( x == 1 )
    return false;
  if ( x == 2 )
    return true;
  return isEven( x - 2 );
}

You do that by adding ``` above and below it. To force single line breaks, you can terminate your sentences with two spaces, or a backslash.

Not only that, but there are also two arrows on this map going into the UK. It’s up to the UK to take care of how well these arrows connect to important locations within their borders. There really doesn’t appear to be an issue whatsoever.

Agreed. In the past you would pay for calling and text messages and data was often unlimited at the higher tiers, but since nobody pays extra for calling and texting anymore, they’re now charging for data. Luckily they can’t charge extra for EU roaming anymore.

Data caps on landlines is something that I haven’t seen for a very long time in my EU country. The last time I had a subscription with a data cap must have been with a 56k modem, if at all. Cable and DSL might have had fair use policies back in the day (or maybe they still do, who knows), but no hard cap. Or at least not that I can remember.

Internet nowadays is way too important to have data caps, especially at home. 5G should definitely be next. Differentiate in speed all you want, but ditch the caps.

Some of those options exist in Bash too, but need to be enabled in your profile: https://www.gnu.org/software/bash/manual/html_node/The-Shopt-Builtin.html. Bash is also more like to be available on random machines that you have access to. Lastly, if you’re working a lot with Bash scripts in your (work) environment you might feel more at home using Bash in interactive mode too.

Those are just some counter arguments for the sake of completeness. I think zsh is great, even though I personally don’t use it (yet).
