If you have a Raspberry Pi running Raspberry Pi OS (previously known as Raspbian) operating system, you know it's an awesome little computer with a great operating system for beginners that includes just about everything you could possibly want. However, once you become familiar with the Pi and want to start using it for other things, you might want an operating system (OS) that doesn't include everything in the default build. read more

The Homebrew project began its life as an unofficial Linux-style package manager for the Mac. Its users quickly fell in love with its friendly interface and helpful prompts, and—in what may seem like a strange twist of fate—it got ported to Linux. read more

If you've ever written code, whether it's a shell script, a Python script, C++, or even Scratch, then you know that variables are vital. Computers and coders use variables as waystations, where they surreptitiously pass information back and forth. For instance, if you need to process a user's name in a shell script, you might set up a variable, put the username into the variable, and then instruct the computer to do something to the variable (check it against a list of authorized users, for example). read more

If you run a server with a public-facing SST access, you might have experienced malicious login attempts. This article shows how to use two utilities to keep the intruder out of our systems. To protect against repeated ssh login attempts, we’ll look at fail2ban. And if you don’t travel much, and perhaps stay in one […]

Productivity is a subjective term, but essentially, it's a measurement of how efficiently a particular task is completed. Everyone has different things that keep them productive—some people need help staying on task, some people need a particular kind of work environment, some people need alerts and reminders to avoid missed deadlines, and some need assistance with repetitive, manual chores. read more

Visual Studio Code, also known as VS Code, is a code editor for Linux, Windows, and macOS. It's the kind of editor that walks the line between editing text and managing your entire codebase, like an integrated development environment (IDE). It's extensible through plugins and has proven to be a reliable text editor that's easily beaten out formidable non-open rival editors. read more
