Using DD to image (backup) an entire hard drive, sector-by-sector, and why you need to save that image on a separate drive.
Viewer Question: Where can you buy Eco Alkalines batteries?
Viewer Question: It would have been nice to have an app to watch you show on my Android device.

{play 36:47}Viewer Question: My girlfriend and I are web page developers, and we love your series on PHP programming. We have a script for our online radio station which allows listeners to make a request which is meant to send an email to the DJ, but it is not working. Can you help?
Looking at the code provided by our viewer and assessing the security and why it doesn't work for the user.
Some serious security exploits in the file provided by our viewer. (Note: watching this after the fact I realize the file output is a SEVERE security risk. You're outputting to .php files, and using a register_globals environment. What that means is, I could do ?content=;exec('rm -rf ~'); from my browser and wipe out your home folder.)
Viewer Comment: The form itself was working fine, but it was only sending the email to the listener, but not the DJ.
The dangers of PHP register_global and why it was removed (see my note above).
Figuring out why this PHP script only mails to the sender, but not the recipient.
Viewer Question: Is it possible to download recorded videos from a Bell PVR to an iPad first-gen?
