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

12 pointscodingclaws41 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)

++i;

x ? x : y

If it has to be one line, the comment:

    You are not expected to understand this.

from https://en.m.wikipedia.org/wiki/A_Commentary_on_the_UNIX_Ope... .

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.

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.

// DON'T TRY TO FIX THIS, IF REMOVED BREAKS PRODUCTION

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.

Good explanation here: https://www.cyberciti.biz/faq/understanding-bash-fork-bomb/

The export-restricted perl munition t-shirt text:

#!/bin/perl -sp0777i<X+dlMLa^lN%0]dsXx++lMlN/dsM0<j]dsj

// TODO: Fix me

Haven't seen this in a while;

There are 10 kinds of people in the world, those who understand binary and those who do not.

and those who mistake it for binary.

that's why it works better with 11

Fast inverse square root

    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.

I have a shirt from WWDC 2014 that I find humorous:

func yTown() { print("San Francisco WWDC 2014") }

body { display: none !important; }

I'm not sure exactly, but I'd probably write it in Whitespace.

20 GOTO 10

  10 PRINT CHR$(205.5+RND(1)); : GOTO 10

System.out.println("Hello World");

const y = f => (x => f(x(x))) (x => f((...y) => x(x)(...y)))

for (;;) { printf("%s\n", "I'm in danger!"); };
