Video Content

  • Hokie doodles! We make a lot of video, and have been doing so since 2007! Browse this site to check out some of the great content, and enjoy! We give it away for free.

System Administration

  • NEMS Linux
    Robbie's world-famous enterprise asset monitoring distro for single board computers. Because sysadmins can't be standing in front of every computer all the time, NEMS Linux will alert you to potential problems, failures and more.




  • Current IP Address
    Output your current IP address without any extra junk like ads. Also supports programmatic and JSON output because that's how Robbie rolls.


  • Set Linux Date and Time
    If your single board computer's date is wrong, you won't be able to browse the web, do system updates, or even perform an NTP clock sync (perhaps ironically). Robbie wrote a tool to make it easier for users to quickly fix this issue with a quick copy-and-paste line of code.

3D Printing

  • Timelapse GCODE Injector
    Take a picture with your DSLR in between each layer of your 3D print by injecting it with Robbie's Timelapse GCODE.
