Re: Just Another <insert language here> Hacker,

C:

main(){int j,u[22]={0};while(!u[12]){while(u[j=rand()%22]++);putchar("atCorhnhteua\nsk eJcr  "[j]);}}

I liked this one a lot!  Can I ask how you came up with it?
Unfortunately it was missing a comma on the end, so I fixed it.  I hope you don't mind:

main(){int j,u[23]={0};while(!u[19]){while(u[j=rand()%23]++);putchar("uatChks rteJ r hon,\neca"[j]);}}

Re: Just Another <insert language here> Hacker,

Oh right, thanks!  I dunno how I came up with it; the typical C hack involves something usually, but not technically, portable (this should work on any system using glibc).  And this was more interesting than printf("Just another C Hacker,\n").

Re: Just Another <insert language here> Hacker,

Just another attempt to write JAPH in assembly.
Definitely not a one-liner.
Works only on x86_64.
Non-optimized (the very code costed me more time than expected, so let it simply work).
PS. Base address 0x004000B0 is vital for the word "Just" to render properly, keep this in mind when linking!
