Q:Alan from Japan: I'm not a security expert, but didn't you just show your PayPal account user name to everyone. If it's a time based system as you say then anyone who also has the same device would be able to enter your PayPal account?
A:During episode 163, Sean demonstrated how the PayPal Security Key worked, by visually showing a one time use key that also requires his password to login to his PayPal account. Each PayPal Security Key is unique to each individual who utilizes this PayPal feature.
Q:Harry from Reading, PA: I have a question about 2.4 and 5 GHz wireless networks. What is a difference and which should I use?
A:The 5 GHz band has a significantly shorter range and cannot penetrate walls and floors containing specific material. While 2.4 GHz has been known to be the best yet alternative to the wired connection. You can get a 802.11n routers today, however the specification will not be finalized until January 2010. 802.11n routers utilize both the 2.4 GHz and the 5 Ghz wireless bands.
Q:Chris: My friend and I have been arguing about which mobile gaming system is the best. We both have a Sony PSP, he has a Nintendo DSi, and I have Apple iPod Touch. Which is better?
A:It's a personal choice. All the handhelds listed have their place. Sean says it really depends of what type of games you like and want to play. The system that plays those games is the right one for you!
Q:Taylor from Wisconsin: I was interested as to how the super computers work and how Folding@Home cluster works. I got started on the project in 2008 at college and since then have built a computer for the dual purpose or high performance and processing power for the research. It might be interesting to see the power of the cluster grow if your viewers were to run this free application on their computers while not in use or during times that the usage is light.
A:Andy and Sean both say it's a worth while project for viewers to consider if they have an idle machine.
Q:Justin from Duluth, MN: I have been watching your show for about a month now and I was wondering if you could explain those who do not know what crossfire and SLI is?
A: Both are competitive gaming technologies that utilize two separate video cards that communicate between the two video cards to enhance the graphics experience.
