What's this? Open Source isn't made from galvanized code, impervious to attack? This can't be! Only Micro$oft software has vulnerabilities, right? Call me sick, but I get smile on my face every time a flaw is discovered in Linux or other notable open source software. It just further validates my long standing belief that "free" software is actually just as bad, if not worse, in terms of security and reliability as any commercial product. Security is an illusion. Every piece of software written by human hand has holes. If you don't believe me, disable your firewall in Linux and OSX and post your IP address. Then sit back and wait for vandals to have their fun with your supposedly "secure" system.

Yes, Windows may be full of holes, but at the end of the day, so is any other OS developed outside Fortress Redmond. Link
