Work related: We sell solutions including CCTV and video-intercom and we have only recently started providing customers with stickers they can use to make those installations comply with regulations. Technically, it has been the responsibility of the customer installing the device, so us doing this is just nudging people towards compliance because nobody cares. I can guarantee you that there are tens of thousands of cameras here filming public ground and it is not prosecuted. In fact, someone at the office put one up a long time ago for a PTZ demo (not recording) that was not compliant and it took almost 10 years until we got ordered to take it down.

Most of these are not recording, only recording situationally or only locally. Still not legal technically. However, ever since cheap cloud-connected doorbells have become available, they have definitely been installed here. They do not comply with regulations whatsoever and next to nothing is done about it.

Hope this clears things up. My main point was that there is in fact an incentive for users to check the app beyond setting up payment and forgetting about it. Even if it is not the only way such content is available, it certainly is a convenient one.

However, I do strongly agree with you that setting a boundary to "normal" and therefore implying these states to be abnormal and something that needs to be fixed is not helpful. We should be able to label a wide spectrum of neurological wiring quirks without nudging people towards changing them, unless it actually negatively impacts their ability to live a fulfilling life.

Task failed successfully.

Humans should be able to interact politely in any setting and if they don't, the issue needs to be settled with good old human interaction anyways.

It's free, including exercises and an (also free) solutions book.

I agree that this is not an ideal start - at least without any further clarification - for beginners but I think it works well for people that already known mathematical notation but not many specifics of linear algebra.

Also, I don't want to be the preacher bringing this into every argument but this is one of the genuinely good uses for AI that I have found. Bringing the beginning of a beginner friendly work down to my level. I can have it explain this if I'm unsure about the specific syntax and it will convey the relevant idea (which is explained in a bit of unnecessary complexity / generality, yes) in simple terms.

Talking about stuff like this:

      nodes =
        node_data
        |> Input.split_by_line(trim: true)
        |> Enum.map(fn <<
                         t::binary-size(3),
                         " = (",
                         l::binary-size(3),
                         ", ",
                         r::binary-size(3),
                         ")"
                       >> ->
          {t, {l, r}}
        end)
        |> Enum.into(%{})
