(n) A Linux user capable of Ninja-like actions. Usually the user has several years of experience in reverse-engineering, exploitation,
scripting, and/or system administration. A linja is not necessarily malicious, but is more concerned with stealth, knowledge, and the yin/yang of computer systems.
Update your Windoze system regularly with all the latest, greatest security patches, or you might get pwned by a Linja Master like r00t or Aleph One.
