Don't teach how to remove viruses. That is a moving target. Teach how viruses spread though specific examples. I think cross site scripting (XSS) is easy to teach them once they've done a little html authoring and had a little javascript programming. For this socially networked generation it applies to stuff they use EVERY hour of every day. A few of there were probably hit by that mouseover twitter exploit a few weeks ago. You can run an intentionally vulnerable server such as mutillidae to practice the exploits. http://www.irongeek.com/i.php?page=security/mutillidae-deliberately-vulnerable-php-owasp-top-10 Read up on current exploits at http://owasp.org/ The future needs people to know how to not create exploits, and patch the ones they do. We don't need more IT "next clickers" who only know how to run third party solutions.

For me it's a matter of music I know versus Music I don't. At my job as a software developer for a sales company the office is always loud. So I need music to drown out people discussing there projects in the cube next to me, or sales ringing the "I just closed a deal bell". I find instrumental music of all kinds great for blocking the background noise. If the music has lyrics I need to have already heard the song a few times otherwise I get distracted by the songs lyrics. I don't mean to eavesdrop, but without headphones I get distracted by ever conversation in earshot. If my boss said no more headphones, I'd need to find new work ASAP. It would be too frustrating otherwise. So anyone else think it's a matter of music you know versus music you don't?

well some really cheap sensor ideas shared with me by the YAAARC guys at the con was a laserpoint fixed in relation to a cheap webcam. the lower the dot the closer the object. survey quality GPS is out there and commercially available. it can get resolutions in feet and inches. it is rather pricy for a user but ORPP is for consultants.
