This week we chat with Chris Dixon, a general partner at Andreessen Horowitz, where he helps lead its Crypto Fund. Dixon and a16Z are now launching a new Crypto Sartup School devoted to educating young developers and entrepreneurs interested in the crypto space.

You can check out the back story of Dixon’s first company, SiteAdvisor, here. It was built during a time when spyware was a booming business and browsers had few systems in place to combat bad actors. The company was acquired by McAfee in 2006. It’s a great trip through the history of web security at the time. …

Considering the code works and all you seem to want is a review of the code, then I suggest you post on the Code Review SE site instead. — Some programmer dude 17 secs ago

By asking if the code was a security risk, the assumption was that it was working code, but maybe not the best code it could be... that's why I suggested the codereview site. I would write a new question, and make it clear (with better formatted code, so it's not in a single line) that your code isn't working... and explain what the issue is... what it's doing, what it's not doing etc. There's no point trying to resurrect this question with -5 — freefaller 29 secs ago
