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.

Recently, I demonstrated how to implement full-drive encryption on Linux with LUKS and the cryptsetup command. While encrypting a whole drive is useful in many cases, there are reasons you might not want to encode an entire drive. For instance, you might require a drive to work across several platforms, some of which may not have Linux Unified Key Setup (LUKS) integration. read more
