DayZ Safe Zone Maker

I didn't see a tool for this out there, so I thought I'd write this as a mobile-friendly web page hosted on GitHub pages that can be used from a browser.  100% JavaScript.

DayZ community server admins sometimes create "safe zones" on the map where players can go to trade or buy a house.  Admins often want to remove all the hostile spawns from that safe zone but there is no easy way to find all the edits that need to be made.

Raspberry Pi for your home network

The Raspberry Pi can provide a great deal of functionality to your home network.  Here are some uses I recommend:

1. Encrypted DNS
   So your ISP can't log what sites you visit and sell this data to marketers
2. Ad Blocking
   Significantly speed up browsing for all your home devices
3. Encrypted FTP
   Securely send and receive large files with friends and business partners
4. Route 53 Dynamic DNS
   So your FTP address (ftp.domain.tld) always points to your public IP

Raspberry Pi Security Camera Viewer

Most high-definition televisions have a "Picture-in-Picture" feature that is useless; if you are watching a HD input the PIP window can only display a low-resolution input such as RF or Composite SDTV.  Furthermore the sole Composite video input is often combined with the Component video input which may already be used by your older video game console. 

What's left?  I'll show you how to use your HDTV's coaxial cable TV RF input to view up to four network security cameras in the PIP window so you can keep an eye on your perimeter while watching something else.
