Pi-hole is a little open source Linux-based DNS ad blocker that you run on your network to soak up all the ad junk before it hits your browser.

I tried it in a VM and was amazed at the speed difference it made despite the fact I already have uBlock Origin installed in my browsers.

I decided to get a Raspberry Pi 3 from Amazon (the starter kit with Pi, case, micro usb, and power cord). I had Pi-hole installed and configured within a few minutes and it works beautifully. The speed gains are very noticeable.

I strongly recommend this, and encourage anyone who uses it to support the project.
