I started brewing my own beer more than 10 years ago. Like most homebrewers, I started in my kitchen making extract-based brews. This required the least equipment and still resulted in really tasty beer. Eventually I stepped up to all-grain brewing using a big cooler for my mash tun. For several years I was brewing 5 gallons at a time, but brewing 10 gallons takes the same amount of time and effort (and only requires slightly larger equipment), so a few years ago I stepped it up. read more

Off-the-shelf, consumer home automation has fallen into a pretty standard pattern. You have a smart device (like a lightbulb or door lock) that talks to some kind of hub that you put on your network. It communicates with a cloud service owned by the device vendor, and you interface with that service via a mobile app. This provides an easy out-of-the-box experience and lets the vendor iterate on its service both in the cloud and on mobile; however, this model has a lot of weaknesses and is extremely limiting with what it can do. read more

If you use open source software, chances are you'll encounter a .tar file at some point. The open source tar archive utility has been around since 1979, so it is truly ubiquitous in the POSIX world. Its purpose is simple: It takes one or more files and "wraps" them into a self-contained file, called a tape archive because when tar was invented it was used to place data on storage tapes.

If you're looking for a tool that lets you do all this (and much more), you will be glad to know there exists a command - dubbed date - that does all this.
