Major power and telephone grids have long been controlled by computer networks, but now similar systems are embedded in such mundane objects as electric meters, alarm clocks, home refrigerators and thermostats, video cameras, bathroom scales, and Christmas-tree lights - all of which are, or soon will be, accessible remotely.

For the average home-user, anti-virus software is a must. A personal firewall such as Zone Alarm and running a program like HFNetcheck, which is a free download for personal users. It checks your system to see if anything needs to be patched. I'd also recommend a program such as SpyCop to periodically check for any spyware on your system.

In 2006, I appeared before a House subcommittee considering real estate reform. It was like visiting the capital for the 'Hunger Games' as an outsider in a glamorous and byzantine fairy tale: I couldn't believe how beautiful all the congressional aides were, and I never understood the system of bells and alarms warning legislators to vote.

The thing that alarms me is that there are so many clergymen who say that the so-called 'new morality' is all right. They say we're living in a new generation; let's be relevant, let's change God's law. Let's say that adultery is all right under certain circumstances; fornication's all right under certain circumstances. If it's 'meaningful.'

I typically set at least three alarms. I have two alarms set on my iPhone, I still use a Blackberry for work, so I set my alarm on that, and then if I'm staying in a hotel, I request a wake-up call. I've never overslept - knock on wood. But I have had an instance where one of my four alarms has failed, so that's why I stand by the multiple alarms.
