4 Mac terminal customizations even a curmudgeon can love

My Linux story: From Linux user to contributor

1 hour 5 min ago

I am an IT professional with over 15 years of experience in a number of different roles—systems administrator, senior Linux administrator, DevOps engineer, automation consultant, and senior scrum master. I started learning Linux on Ubuntu but shifted to CentOS as a sysadmin, and later I moved to Fedora for personal use.

What you need to know about automation testing in CI/CD

Thursday 9th of July 2020 07:02:00 AM

"If things seem under control, you're just not going fast enough." —Mario Andretti

Test automation means focusing continuously on detecting defects, errors, and bugs as early and quickly as possible in the software development process. This is done using tools that pursue quality as the highest value and are put in place to ensure quality—not just pursue it.

Expand your Raspberry Pi with Arduino ports

Thursday 9th of July 2020 07:02:00 AM

As members of the maker community, we are always looking for creative ways to use hardware and software. This time, Patrick Lima and I decided we wanted to expand the Raspberry Pi's ports using an Arduino board, so we could access more functionality and ports and add a layer of protection to the device. There are a lot of ways to use this setup, such as building a solar panel that follows the sun, a home weather station, joystick interaction, and more.

Making compliance scalable in a container world

Thursday 9th of July 2020 07:00:00 AM

Software is increasingly being distributed as container images. Container images include the many software components needed to support the featured software in the container. Thus, distribution of a container image involves distribution of many software components, which typically include GPL-licensed components. We can't expect every company that distributes container images to become an open source compliance expert, so we need to build compliance into container technology.

Program IoT systems using Python with this VSCode plugin for RTOS

Wednesday 8th of July 2020 07:02:00 AM

The pervasiveness of the Internet of Things (IoT) means nearly every product, from refrigerators to pocket watches, can connect to a network. For that to happen, all these products must have an embedded computer running a networking stack, and some of these products are almost impossibly small. That's where embedded software comes in: modern technology provides a tiny computer, hard-coded into a hardware chip, without any need for offboard CPU, RAM, or hard drive.

Why I stick with xterm

Tuesday 7th of July 2020 07:01:00 AM

What's my terminal of choice?

I use xterm. That's right, xterm. It may seem like an old school choice, and I do use GNOME 3 now as well, but after many years of trying some and ignoring others, then going back to old standbys, I find I don't need (or like) newer stuff like GNOME Terminal.

My philosophy: Start simple, improve over time, and aim for productivity.
