C (K&R) program that calculates PI number by measuring circle that is its code: https://en.wikipedia.org/wiki/International_Obfuscated_C_Cod...
Perl one-liner that checks if a number is prime: perl -lne '(1x$_) =~ /^1?$|^(11+?)\1+$/ || print "$_ is prime"'
I like this bit of JavaScript for uniquifying an array: array.filter((item, index, arr) => arr.indexOf(item) === index) It works because indexOf returns the index of the first occurrence of the item, so you're asking whether this occurrence is the first occurrence.
array.filter(Boolean)Earlier quoted context omitted.
I love the SQLite guy. His own version control, his own DB engine; you can tell from the site that he’s an individualist!
He mentioned on a podcast that he even uses his own text editor.
For me it's a BASIC one-liner which generates mazes 10 PRINT CHR$ (205.5 + RND (1)); : GOTO 10 I found this specific one via slashdot[1], but something similar, which I've never managed to find/replicate, was used to generate mazes on the Atari 800 XL at my school when I was a kid.

perl -C -e 'print chr(9585.5+rand) while 1'

I remember being fascinated with Pascal program that makes snow fall.
Basically, it was white dots on a blue background in an infinite loop. :)

I dunno. The security ramifications of those few lines of code make me squirm. It's like looking at a very beautifully constructed foot gun. I wonder how much damage that code has caused.
At the time the code was written, the security ramifications were not quite the same as they are now. Even now, I would suggest that there are times where such a construction would be just fine.

No, it does not generate a maze. It generates a random sequence of \s and /s, that can trigger a maze being generated in a typical user's mind. This is the art of illusion.
What is a maze? One could argue that if the user perceives a maze, then it produces a maze.
I began coding in IBM/LCSI PC Logo. The first line of code I ever wrote was: FD 100 That's the "hello, world" of turtle graphics in Logo. While probably not as beautiful as the several splendid examples posted in this thread, that simple line of code changed my world. I could make stuff happen in an otherwise mostly blank monochrome CRT display. Until then I had seen CRTs in televisions where I had very little contro…
Oh man, PC Logo takes me back down the memory lane. We were introduced to PC Logo in 4th grade, that's about 9 years ago. I instantly fell in love with it. The amount of power I had over the computer - ordering it to draw what I want, how I want was really exciting. My father had installed Kubuntu on our home computer which had an amazing suite of educational applications, including KTurtle which was (almost) the sam…
