Significantly improve your productivity when running multiple instances of Fedora Linux by installing the DNF local plugin!

Like many people, I've been exploring lots of new TV shows during the pandemic. I recently discovered a British game show called Countdown, where contestants play two types of games: a words game, where they try to make the longest word out of a jumble of letters, and a numbers game, where they calculate a target number from a random selection of numbers. Because I enjoy mathematics, I've found myself drawn to the numbers game. read more

Because so much of our personal and professional data is available online today, it is important for everyone—from professionals to general internet users—to learn the basics of security and privacy. As a student, I've been able to gain experience in this area through my school's CyberPatriot initiative, where I've had the opportunity to interact with industry experts to learn about cyber breaches and the basic steps to establish a system's security.

When the personal computer was young, a household was likely to have one (or fewer) computers in it. Children played games on it during the day, and parents did accounting or programming or roamed through a BBS in the evening. Imagine a one-computer household today, though, and you can predict the conflict it would create. Everyone would want to use the computer at the same time, and there wouldn't be enough keyboard and mouse to go around.

Most people tend to take name services for granted. They are necessary to convert human-readable names, such as http://www.example.com, into IP addresses, like 93.184.216.34. It is easier for humans to recognize and remember names than IP addresses, and name services allow us to use names, and they also convert them to IP addresses for us.

Shortcuts? What shortcuts! Sponsored Without a doubt, Kubernetes is the most important thing that has happened in enterprise computing in the past two decades, rivalling the transformation that swept over the datacenter with server virtualization, first in the early 2000s on RISC/Unix platforms and then during the Great Recession when commercial-grade server virtualization became available on X86 platforms at precisely the moment it was most needed.…

Linux is famous for its commands. This is partially because nearly everything that Linux does can also be invoked from a terminal, but it's also that Linux as an operating system is highly modular. Its tools are designed to produce fairly specific results, and when you know a lot about a few commands, you can combine them in interesting ways for useful output. Learning Linux is equal parts learning commands and learning how to string those commands together in interesting combinations.

Anyone who spends a lot of time working with Git will eventually need to do some form of context switching. Sometimes this adds very little overhead to your workflow, but other times, it can be a real pain. Let's discuss the pros and cons of some common strategies for dealing with context switching using this example problem.
