Security through obscurity just got a whole new meaning. Hackers managed to steal gigabytes of proprietary Lisp code, but joke's on them—they only got the second half of the files, which means nothing but closing parentheses. For those blissfully unaware, Lisp is famous (or infamous) for its ((((nested parentheses)))) that go so deep you need a map and a prayer to find your way back. The opening parentheses contain all the actual logic, while the closing ones are just... well, a parade of )))))))) at the end. So the hackers basically stole a file that looks like someone held down the shift+9 key for an hour. This is unintentionally the most effective code protection ever devised. Forget encryption, just write everything in Lisp and let the parentheses do the heavy lifting.
