Over the past few years, it's become difficult to find a website that is just "http:// …" This is because the industry has finally realised that security on the web is "a thing," and also because it has become easy for both servers and clients to set up and use HTTPS connections. A similar shift may be on its way in computing across cloud, edge, Internet of Things, blockchain, artificial intelligence, machine learning, and beyond.

When you work with computers all day, it's fantastic to find repeatable commands and tag them for easy use later on. They all sit there, tucked away in ~/.bashrc (or ~/.zshrc for Zsh users), waiting to help improve your day! In this article, I share some of my favorite of these helper commands for things I forget a lot, in hopes that they will save you, too, some heartache over time. read more

Contributing to open source as a hobby is a great way to dip your toes in the water on a new technology—and maybe even advance your career in the process. IBM software engineer Tara Gu found both of those things to be true when she started contributing to the Kubernetes container engine project in 2018.

Back in early 2014, I purchased my first ARM-based computer, a SolidRun CuBox-i4. My goal for the CuBox was to have a headless device (e.g., no display) that takes up minimal space in the audio equipment shelf, makes minimal noise, and serves music files to my digital-to-analog converter (DAC) and thus to the rest of the stereo. On paper, the CuBox was a perfect fit. read more

In my work as a programming language researcher, I need to create artifacts that are easy to understand and well-documented. To make my work easier, I found a simple way to automate generating source code documentation, creating HTML and PDF versions of user documentation, compiling a technical (research) document to PDF, generating the bibliography, and provisioning of virtual machines with the software artefact installed for ease of reproducibility of my research.

As a sysadmin, every day I am faced with problems I need to solve quickly because there are users and managers who expect things to run smoothly. In a large environment like the one I manage, it's nearly impossible to know all of the systems and products from end to end, so I have to use creative techniques to find the source of the problems and (hopefully) come up with solutions.

Sway is a tiling Wayland compositor which has mostly the same features, look and workflow as the i3 X11 window manager. Because Sway uses Wayland instead of X11, the tools to setup X11 don’t always work in sway. This includes tools like xrandr, which are used in X11 window managers or desktops to setup monitors. […]

When you're standing on a stage or doing a live demo in an online session, getting your project into a perfect-looking state may appear easy. But a lot of work goes on behind the scenes to create working, easy to use, and repeatable demo projects. When you're doing a demo, the technology in a project must support your bigger story about the project without failing. My fellow JBoss technology evangelists and I often have to set up different technologies, so it became necessary for us to tune some sort of generic framework or template to put these demo projects into. read more
