Try this line of javascript in a browser:

<pre id=p><script>n=setInterval("for(n+=7,i=k,P='p.\\n';i-=1/k;P+=P[i%2?(i%2*j-j+n/k^j)&1:2])j=k/i;p.innerHTML=P",k=64)</script>

Nice! I feared rm -rf / 😌

Woah

@lo98be yes this too, it added the task to be executed when you write more than 20 lines of code without saving

This is a sudoku solver, it works just passing an array of 81 numbers as first parameter (0 for void tiles):

function R(a,i,j,m,g){for(i=80;a[i];i--||A);for(m=10;g=a[i]=--m;g&&R(a))for(j in a)g*=i==j||a[j]^m||i/9^j/9&&i%9^j%9&&i/27^j/27|i%9/3^j%9/3}

@apisarenco Wow, can you come to my party! You sound fun :D
