Two open-spec boards with Lattice ECP5 FPGAs can run Linux via a VexRiscv softcore. GsD’s $99 Orange Crab has a tiny Feather form factor while Radiona.org’s $115 to $155 ULX3S supports beefier ECP5 models and adds an ESP32. Almost all the FPGA-based development boards we cover use SoCs that also provide Linux-friendly Arm Cortex-A cores, […]

Grammarly is popular among many teachers, students, business people, and others who need to write or process a lot of words on a regular basis. It's a useful tool, but you're required to register and log in to use it, and I rarely keep website login data in my cache.

DevOps? On a mainframe!? Yes, it's true. Red Hat is bringing Ansible to the IBM Z.

Google Compute Engine lets you use virtual machines that run on Google's infrastructure inside the Google Cloud Platform. In this article, we will demonstrate how to create a virtual machine (vm) using the Ubuntu 18.04 boot disk image in Google Cloud Platform (GCP).

If you work from home, you know how important it is to have a great set of tools that stay out of your way and let you focus on what matters. The harder you work during work hours, the more easily you can relax once the workday is through. I've been working from home for years, and here are my top picks for the best tools open source has to offer the remote worker. Jitsi video conferencing read more

I've had moments as a software engineer when I'm asked to do a task that sends shivers down my spine. One such moment was when I had to write an interface between some new hardware infrastructure that requires C and a cloud infrastructure, which is primarily Python. read more

The Twisted Requests (treq) package is an HTTP client built on the popular Twisted library that is used for asynchronous requests. Async libraries offer the ability to do large amounts of network requests in parallel with relatively little CPU impact. This can be useful in HTTP clients that need to make several requests before they have all the information they need. In this article, we'll work through an example of making async calls to explore using treq. read more

Many open-source projects are taking on the challenge of conquering COVID-19.

X-Cart is an extremely flexible open-source eCommerce platform with tons of features and integrations. This guide describes the process of installing X-Cart 5 on Debian 10 by using Nginx as a web server and MariaDB as a database server.

During the 1960s and 1970’s, software developers typically used monolithic architectures on mainframes and minicomputers for software development, and no single application was able to satisfy the needs of most end-users. Vertical industries used software with a smaller code footprint with simpler interfaces to other applications, and scalability was not a priority at the time.

Chai is prepping a Coronavirus Environmental Testing Kit for its open source, BeagleBone-based Open qPCR system. The kit can test surfaces for Covid-19 from swab samples and return results within the hour. BeagleBoard.org announced that it will be donating BeagleBone Black SBCs for Chai’s project to widely deploy a Covid-19 environmental test kit that will […]

MySQL is a free, open-source and one of the most popular database systems around the globe. In this tutorial, we will show you how to install MySQL 8 on CentOS 8 server.

Testing often begins with what we hope happens. In my previous article, I demonstrated how to virtualize a service you depend on when processing the "happy path" scenario (that is, testing the outcome of a successful login attempt). But we all know that software fails in spectacular and unexpected ways. Now's the time to take a closer look into how to process the "less happy paths": what happens when someone tries to log in with the wrong credentials?

Glance is an image service that allows you to discover, provide, register, or even delete disk and/or server images. It is a fundamental part of managing images on OpenStack and TripleO (which stands for "OpenStack-On-OpenStack").

Adafruit’s DIN Rail Mount Bracket for the Raspberry Pi, BeagleBone, and Arduino costs $20, or $37 with a terminal block breakout adapter and cable. We also look at RPi DIN rail housings from DINrPlate, Phoenix Contact, and Zihatec. We have covered plenty of compact industrial computers with optional or standard DIN rail mounts, including Kunbus’ […]
