The cloud has become synonymous with all things data storage. It additionally equates to the many web-centric services accessing that same back-end data storage, but the term also has evolved to mean so much more. This weekend join us as we explore the cloud. CloudWatch Is of the Devil, but I Must Use It by Corey Quinn Let's talk about Amazon CloudWatch.

Continuous integration and continuous delivery (CI/CD) is all the rage in the modern world of software development. But actually what is this pipeline process? It's a method or set of principles for which development teams implement and deliver code more frequently and reliably. Continuous integration embodies a coding philosophy and set of practices propelling teams to implement small and frequent code changes into version control repositories, while the continuous delivery picks up where the CI ends and automates the application's delivery

  In my first post on removing duplicate PATH entries I used an AWK one-liner. In the second post I used a Perl one-liner, or more accurately, I tried to dissect a Perl one-liner provided by reader Shaun. Shaun had asked that if I was willing to use AWK (not Bash), why not use Perl? It occurred to me that one might also ask: why not just use Bash? So, one more time into the void.

Docker provides a powerful tool for creating lightweight images and containerized processes, but did you know it can make your development environment part of the DevOps pipeline too? Whether you're managing tens of thousands of servers in the cloud or are a software engineer looking to incorporate Docker containers into the software development life cycle, this article has a little something for everyone with a passion for Linux and Docker.

An introduction to an application server that allows you to build MySQL user interfaces without programming. Assume you are tasked to write a browser-based, MySQL user interface for the table called CITY. CITY has two columns. The column names are city_name and state_code—each combined are the primary key. Your user interface must enable users to execute the four main SQL operations: select, insert, update and delete. The main characteristics for each operation are:

Learn how to embrace open standards while you remove stubble.

Testing functions isn't hard, but how do you test user input and output? In my last article, I started looking at "pytest", a framework for testing Python programs that's really changed the way I look at testing. For the first time, I really feel like testing is something I can and should do on a regular basis; pytest makes things so easy and straightforward.

Is there room for FOSS in the AI, VR, AR, MR, ML and XR revolutions—or vice versa? Will the free and open-source revolution end when our most personal computing happens inside the walled gardens of proprietary AI VR, AR, MR, ML and XR companies? I ask, because that's the plan.

This series covers sysadmin basics. The first article explains how to approach alerting and on-call rotations as a sysadmin. In the second article, I discuss how to automate yourself out of a job, and in the third, I explain why and how you should use tickets. The fourth article covers some of the fundamentals of patch management under Linux, and the fifth and final article describes the overall sysadmin career path and the attributes that might make you a "senior sysadmin" instead of a "sysadmin" or "junior sysadmin", along with some tips on how to level up.
