Java comes with a core set of libraries, including those that define commonly used data types and related behavior, like String or Date; utilities to interact with the host operating system, such as System or File; and useful subsystems to manage security, deal with network communications, and create or parse XML. Given the richness of this core set of libraries, it's often easy to find the necessary bits and pieces to reduce the amount of code a programmer must write to solve a problem. read more

These three tools are often considered the trifecta network troubleshooting tools for a reason.

Recently, my husband was telling me about an upcoming job interview where he would have to run through some basic commands on a computer. He was anxious about the interview, but the best way for him to learn and remember things has always been to equate the thing he doesn't know to something very familiar to him. Because our conversation happened right after I was roaming the grocery store trying to decide what to cook that evening, it inspired me to write about kubectl and Helm commands by equating them to an ordinary trip to the grocer. read more

When you're running containers with Kubernetes, you often find that they pile up. This is by design. It's one of the advantages of containers: they're cheap to start whenever a new one is needed. You can use a front-end like OpenShift or OKD to manage pods and containers. Those make it easy to visualize what you have set up, and have a rich set of commands for quick interactions. read more

Kickstart installations let us easily script and replicate unattended or semi-unattended installations of Fedora, Red Hat Enterprise Linux or CentOS. The instructions needed to install the operating system are specified, with a dedicated syntax, inside a Kickstart file which is passed to the Anaconda installer.

Decision making is one of the most fundamental concepts of computer programming. Python supports the common flow control statements found in other languages, with some modifications. The if control statement is one of the most basic and well-known statements that is used to execute code based on a certain condition.

I met Brendan Becker working in a computer store in 1999. We both enjoyed building custom computers and installing Linux on them. Brendan was always involved in several technology projects at once, ranging from game coding to music composition. Fast-forwarding a few years from the days of computer stores, he went on to write pyDance, an open source implementation of multiple dancing games, and then became the CEO of music and gaming event MAGFest. Sometimes referred to as "Mr. read more

MPD, as the name implies, is a Music Playing Daemon. It can play music but, being a daemon, any piece of software can interface with it and play sounds, including some CLI clients.

One of the most exciting things about YaCy, however, is the fact that it's a local client. Each user owns and operates a node in a globally distributed search engine infrastructure, which means each user is in full control of how they navigate and experience the World Wide Web. read more
