There has been no appreciable improvement in our country's ability to produce the kind of talent we need in this space. There have been some small initiatives around the country that have been noteworthy.

What we are seeing now is customers shifting their attention from security products like firewalls and intrusion sensors, to the policies that need to be in place, and the technologies that help them enforce policy compliance.

Right now we have a closure rate between discovery and exploitation of four to six months. We need to be more in the realm of seven to 10 days. That is an enormous challenge.

Second issue is the rapidly accelerating increase in the number of vulnerabilities that get discovered every day. And, equally importantly, is the shortening of time between the discovery of the vulnerability and the release of an exploit.

The interesting thing about the Internet is that it has created a kind of alternative circle of friends for people.

A goal of Twitch is to be wherever gamers are, whether it's on laptops and handheld devices or integrated into gaming consoles and software.

Not to be biased, but digital wallets are awesome.

The new freedom of expression brought by the Internet goes far beyond politics. People relate to each other in new ways, posing questions about how we should respond to people when all that we know about them is what we have learned through a medium that permits all kinds of anonymity and deception.
