  • Set the order of task execution in Ansible with these two keywords | Enable Sysadmin

    Regular readers of Enable Sysadmin know that most of us are big fans of Ansible. We particularly like using Ansible roles to design reusable code effectively. A playbook follows a specific execution order when it runs, and there are several ways to control the order in which your tasks run. In this article, I'll look at two particularly useful Ansible features, pre_tasks and post_tasks. I'll walk you through some real (and simple) examples of how these features can add additional flexibility to your playbooks by executing tasks at different points during a playbook run.

A deep dive into Raspberry Pi Zero 2 W’s power consumption

When I completed my review of Raspberry Pi Zero 2 W, I mentioned I would test the power consumption of the board later. It took a while, but I’ve finally come around it using Otii Arc from Qoitech and Otii software to provide some pretty power consumption charts, and even energy consumption. Since the Raspberry Pi Foundation recommends a 5V/2.5A power supply, I’ll first try to get as close as possible as 2.5A, then I’ll go through tricks to reduce idle power consumption to less than 75 mA / 375 mW, and finally check the energy consumption under various CPU core count and frequency. I started with the latest Raspberry Pi OS Lite “BullEyes” image and connected my Raspberry Pi Zero 2 W board to Qoitech Otii Arc tools as shown below. It used to cost around $500, but now pricing starts at $699, and it’s a great tool for people developing battery-powered devices, and I admit it’s a bit over the top, but the purpose of this post, but it still does the job.

13 Best Free and Open Source Build Systems

Build automation is the process of automating the creation of a software build and the associated processes including: compiling computer source code into binary code, packaging binary code, and running automated tests. This type of software takes as input the interdependencies of files (typically source code and output executables) and orchestrates building them, quickly. In the beginning, Make was the only build automation tool available beyond home-grown solutions. Make has been around since 1976. Make remains widely used, especially in Unix and Unix-like operating systems. But there are lots of other high quality build systems Here’s our recommendations captured in a legendary LinuxLinks chart. Read more

Jolla: Congrats UK, we’re back!

Last month, as part of our 10-year celebrations, we announced that we’re working to expand the Sailfish X availability to include new countries in addition to the current EU, Norway, and Switzerland. Now we have great news for you: we have re-opened Sailfish X sales in the UK! The UK has always been a stronghold for Sailfish OS. This started already in the early days when many Brits decided to purchase the Jolla phone and start their Sailfish OS journey. Over the years, our developer community and fan base has grown in the UK, and many of our employees (aka sailors) are also from this great island nation. All this in mind, we were disappointed when we had to leave the UK for a while (Brexit), but now we are thrilled to start again! Read more
