Kernel development is always strange. Andrea Parri recently posted a patch to change the order of memory reads during multithreaded operation, such that if one read depended upon the next, the second could not actually occur before the first.

At a recent Ansible London Meetup, I got chatting with somebody about automated hardware builds. "It's all cloud now!" I hear you say. Ah, but for many large organisations it's not—they still have massive data centres full of hardware. Almost regularly somebody pops up on our internal mail list and asks, "can Ansible do hardware provisioning?" Well yes, you can provision hardware with Ansible… read more

In this tutorial, I will show you how to set up a development environment for Ruby on Rails applications using Docker and Docker compose. We will be using Ubuntu 18.04 as the hosts operating system.

If you live your life in plaintext, there invariably comes a time when someone asks for a word processor document. I run into this issue frequently, especially at the Day JobTM. Although I've introduced one of the development teams I work with to a Docs Like Code workflow for writing and reviewing release notes, there are a small number of people who have no interest in GitHub or working with Markdown. read more

In my first article in this series about Source-to-Image (S2I), we examined the required files and discussed how the S2I standard works with any programming language, from Python to Ruby to Go. Now let's explore designing an S2I build specifically for a Go application. A disclaimer: I still like to call Go "Golang" even though it's not officially called that. read more

Audeme has released a $6.50 “Raspberry Pi MOVI Adapter” board and API to enable a Raspberry Pi pairing with its MOVI Arduino Shield for offline speech recognition and synthesis. We’re used to seeing Arduino compatible, MCU-driven HATs and other add-ons for the Raspberry Pi, but in 2015 Audeme flipped that combo on its head with […]

Telnet is a client-server protocol that connects to a remote server through TCP over port 23. Telnet does not encrypt data and is considered insecure and passwords can be easily sniffed because data is sent in the clear. However there are still legacy systems that need to use it. This is where stunnel comes to […]

Source-to-Image is an excellent tool for building container images for applications in a fast, flexible, and reproducible way. Usually abbreviated as S2I, Source-to-Image takes a base "builder" image with all the libraries and build tools needed to compile an application or install dependencies (like Python's PIP or Ruby's Bundler) and a set of scripts in predefined locations that are used to build, test, and run the application. read more

Configuring a network connection from a Linux machine can be challenging. Fortunately, many new Linux distributions come with some type of network management tool that can help you automatically connect to a wireless network. read more
