Ask HN: What single line of code would you put on a programming shirt?

12 pointsby codingclawsvor 2 Jahren41 comments

If you were going to make a programming shirt with one line of code or one expression on the front of the shirt right in the middle what would it be? Examples:

(+ 1 2)

or

++i;

or

x ? x : y

If it has to be one line, the comment:

    You are not expected to understand this.

Though, now that I think about it, I'm pretty sure I've already seen that as a t-shirt.

Is that a shell script? Doesn’t seem to do anything on my linux server.

trealiravor 2 Jahren

It's a fork bomb in shell script. It's more human readable like this:

  bomb() { 
    bomb | bomb &
  }; bomb

Apparently this trick doesn't work nowadays due to cgroups:

Just kidding :)

First thing you learn in unix is to not paste gibberish in terminal.

If the footwear was appropriate, you could say something like:

>BOOT DEVICE NOT FOUND;

>FALLING BACK TO SNEAKERNET . . .

Bash fork bomb. In fact, I have the tshirt.

    import pdb; pdb.set_trace()

Or as one of these 'modern' 'linters' like to 'fix' it to:

    import pdb
    
    
    pdb.set_trace()

I second your annoyance with linters doing that.

You can add #noqa at the end of the line to avoid the linter rewrite.

I’d put $year: ERR_REQUIRE_ESM require of ES module strip-ansi not supported, cause people should know that it’s 202x and we are still practically almost already there.
