Ports allow network and internet-connected devices to interact using specified channels. While servers with dedicated IP addresses can connect directly to the internet and make ports publicly available, a system behind a router on a local network may not be open to the rest of the web. To overcome the issue, port forwarding can be used to make these devices publicly accessible.
Internet Relay Chat, or IRC, is one of the most popular chat protocols on the internet. The technology can be connected to the Tor network to create an anonymous and secure chatroom — without the use of public IP addresses.

Private vehicle ownership to a transportation-as-a-service model has already started, and high capability SAE Level 4 vehicles will complete this trend.

First, I would like to explain that among my family members, I am considered somewhat of an oddball. Mostly because of some of the mods that I have performed on a few of my woodworking tools. After I show you what I did to my drill press, you may be inclined to agree. When I first hatch an idea in my little pea brain, the first thing I take into consideration is whether or not this mod is irreversible and will destroy my tool. In the case of my drill press, I determined that it was safe to pr...

Since the invention of the mechanical clock, enclosure of the commons, and proletarianization of labor, the alarm clock has been the bane of our existence.

Microcontrollers are great. You can do anything from water your garden to catch wildlife trash diggers in the act—and on the cheap. I prefer to use the Arduino microcontroller because of the large and helpful community built around the website. Though it is my favorite, there are some drawbacks to using an Arduino board in every project. It gets expensive, the board can take up too much space, and the rat's nest of breadboard wires are a pain to repair.
