A debugger is one of those pieces of software that most, if not every, developer uses at least once during their software engineering career, but how many of you know how they actually work? During my talk at linux.conf.au 2018 in Sydney, I will be talking about writing a debugger from scratch... in Rust! In this article, the terms debugger/tracer are interchangeably. "Tracee" refers to the process being traced by the tracer. read more

Introducing PyMOL, a Python package for studying chemical structures. I've looked at several open-source packages for computational chemistry in the past, but in this article, I cover a package written in Python called PyMOL.

How do you install an application on Linux? As with many operating systems, there isn't just one answer to that question. Applications can come from so many sources—it's nearly impossible to count—and each development team may deliver their software whatever way they feel is best. Knowing how to install what you're given is part of being a true power user of your OS. read more

This week we look at how open source projects are viewed by college students, unusual tools for agile team development, setting up a Raspberry Pi for retro gaming, the future of Kubernetes, and our annual Linux distro poll.

Reuven explores different types of multiprocessing and looks at the advantages and disadvantages of each.

Twenty years ago, when I first started using Linux, finding a distribution that worked, out of the box, was an impossible feat. Not only did the installation take some serious mental acuity, configuring the software and getting connected to the Internet was often a challenge users were reluctant to attempt. Today, things are quite different. Linux now offers distributions that anyone can use, right out of the box. But, even among those distros that “just work,” some rise to the top to stand as the best in breed.

The web browser has become a critical component of the computing experience for many users. Modern browsers have evolved into powerful and extensible platforms. As part of this, extensions can add or modify their functionality. Extensions for Firefox are built using the WebExtensions API, a cross-browser development system. Which extensions should you install?

This tutorial shows you how to install a MongoDB Sharded Cluster on CentOS 7. Sharding is a MongoDB process to store data-set across different machines. It allows you to perform a horizontal scale of data and to partition all data across independent instances.

Around this time every year, our minds turn to copyright. Or maybe they turn more to copyright. After all, open source works because of copyright law. As you may already know, copyright laws give the authors of works the exclusive right to copy (among other things) their work. These rights attach as soon as the work is fixed in a tangible medium (written down, saved to disk, etc.). So the rights that open source licenses grant rely on copyright law. read more

Most of the Linux commands you encounter do not depend on other operations for users to unlock their full potential, but there exists a small subset of command line tool which you can say are useless when used independently, but become a must-have or must-know when used with other command line operations. One such tool is yes, and in this tutorial, we will discuss this command with some easy to understand examples.

All the major Linux distributions have now released their Intel chip meltdown patches. But, someone must retune all those servers to get their performance up to speed and replace network devices and servers running up-to-date Linux distros.
