  • {play 45:04}Viewer Question: I'm very interested in using a DSLR with Wirecast. Your video using the T2i was very informative. Would using LiveView mode resolve the 30 minute record limit? Also, some people say DSLRs turn off due to overheating. Do you believe this to be true? Have you tried any other setups?
  • {play 50:31}Viewer Question: I've had a P4 3Ghz system with 512 MB RAM and an 80 GB hard drive donated to me. I'd like to stick Linux on it and give it to family to learn Linux. Is there a lightweight distro you'd recommend?
    • Robbie's first choice for a lightweight distro for a beginner Linux user would be Lubuntu. This is because of the lightweight nature of LXDE, plus its ease of use, and the good support from an *buntu-based distro.
    • Next option would be Xubuntu. It's not as sleek and definitely not Robbie's favorite desktop environment, but it's extremely lightweight and very functional.
    • Another thought may be the young Q4OS project, which is making good headway in creating a distro that is easy to use for novice users who are accustomed to Windows XP.

  • {play 57:35}Viewer Question: I'm going to be setting up a home office soon, and wonder if I should setup a NAS or a file server. One of my computers will be doing some CAD work. The other will just be word processing. What do you recommend?
