    There is Carriage Return (CR), and also Line Feed (LF, often called New Line). If you think about old mechanical printers with the metal arm sticking out, a CR operation would move the type head to the far left column, and a LF operation would advance the paper by one line. Variously through the years depending on hardware (typewriter, teletype, those early CRTs that you had to refresh the screen, or modern computers) you would get one or both of those if you pressed Return/Enter, and it’s configurable in software, depending on the software. I don’t know what windows does these days with notepad, but at one time the Enter key sent both (CRLF). UNIX style systems tended to use LF, and older Macs as someone else referenced used CR. If you wrote a generic program to handle anything you had to account for all of them. Mostly these days it gets abstracted away which generally works well enough unless a team of people used a random collection of software to edit a text file.

    printf "\r\nHexadecimal, like that scene from The Martian.\n" | hexdump -C
00000000  0d 0a 48 65 78 61 64 65  63 69 6d 61 6c 2c 20 6c  |..Hexadecimal, l|
00000010  69 6b 65 20 74 68 61 74  20 73 63 65 6e 65 20 66  |ike that scene f|
00000020  72 6f 6d 20 54 68 65 20  4d 61 72 74 69 61 6e 2e  |rom The Martian.|
00000030  0a                                                |.|
00000031

    The 0a is a Line Feed character, and the 0d is a Carriage Return character. In my terminal without piping it through hexdump you get:

    printf "\r\nHexadecimal, like that scene from The Martian.\n"

Hexadecimal, like that scene from The Martian.

    The LF at the end of the string makes it so that the prompt at the terminal doesn’t appear on the same line as the output, and the blank line before the text is caused by the LF at the beginning. I don’t know/care/have to worry about what eats the CR.

    There are so many timelines where this guy ends up dead or in jail. This timeline depended on his ability to get a rep from Jaguar on the phone on a weekend. I can kind of understand the four car response; the system kept dropping him and they finally had positive confirmation this was the car and where it was. I wonder how often clerical/technical errors happen and how early in the process they normally get caught. This could’ve ended as badly as some of the swatting cases have and started out much the same way: an input into a system drives a forceful output. It doesn’t matter to the recipient of the force if it was a prank, a malicious act by someone, or a glitch in the matrix. If someone dies because a bad actor swatted someone there are consequences. What are the consequences if the entire Flock system is pure happy path from lens to server?

    It’s not fear, it’s a mindset that starts with the idea that what they personally want is how the world ought to work. People don’t generally make public arguments that go against their own self interest. Dudebro from the OP’s screengrabs obviously has his sights set on multiple women, so he’s going to say whatever dumb shit that can drag that mindset into whatever group he considers himself to be a part of.

    Or it’s satire and this is Poe’s law in action. Dude should’ve had a winky.
