Please don't do things to make titles stand out...
If the original title begins with a number or number + gratuitous adjective, we'd appreciate it if you'd crop it. E.g. translate "10 Ways To Do X" to "How To Do X," and "14 Amazing Ys" to "Ys." Exception: when the number is meaningful, e.g. "The 5 Platonic Solids."
The word hacker here is gratuitous. The words 'open source' give a clear enough idea of how the site operates. And the site should stand on its own.
(I am amused that TrevorJ managed to think a plausible tie in.)
