7 rules for remote-work sanity

Friday 30th of August 2019 07:00:00 AM

I work remotely and have done so on and off for a good percentage of the past 10 to 15 years. I'm lucky that I'm in a role where this suits my responsibilities, and in a company that is set up for it. Not all roles—those with many customer onsite meetings or those with a major service component—are suited to remote working, of course. But it's clear that an increasing number of organisations are considering having at least some of their workers doing so remotely.

Variables in PowerShell

Thursday 29th of August 2019 07:02:00 AM

In computer science (and casual computing), a variable is a location in memory that holds arbitrary information for later use. In other words, it’s a temporary storage container for you to put data into and get data out of. In the Bash shell, that data can be a word (a string, in computer lingo) or a number (an integer).

What is an Object in Java?

Thursday 29th of August 2019 07:00:00 AM

Java is an object-oriented programming language, which views the world as a collection of objects that have both properties and behavior. Java's version of object-orientedness is pretty straightforward, and it's the basis for almost everything in the language. Because it's so essential to Java, I'll explain a bit about what's under the covers to help anyone new to the language.

Managing Ansible environments on MacOS with Conda

Wednesday 28th of August 2019 07:02:00 AM

If you are a Python developer using MacOS and involved with Ansible administration, you may want to use the Conda package manager to keep your Ansible work separate from your core OS and other local projects.

Ansible is based on Python. Conda is not required to make Ansible work on MacOS, but it does make managing Python versions and package dependencies easier. This allows you to use an upgraded Python version on MacOS and keep Python package dependencies separate between your system, Ansible, and other programming projects.

Wednesday 28th of August 2019 07:00:00 AM

Environment variables contain information about your login session, stored for the system shell to use when executing commands. They exist whether you’re using Linux, Mac, or Windows. Many of these variables are set by default during installation or user creation.

While environment variables apply to all modern systems, this article specifically addresses environment variables in the Bash shell on Linux, BSD, Mac, and Cygwin.

Why Spinnaker matters to CI/CD

Tuesday 27th of August 2019 07:01:00 AM

5 ops tasks to do with Ansible

Monday 26th of August 2019 07:01:00 AM

In this DevOps world, it sometimes appears the Dev half gets all the limelight, with Ops the forgotten half in the relationship. It's almost as if the leading Dev tells the trailing Ops what to do, with almost everything "Ops" being whatever Dev says it should be. Ops, therefore, gets left behind, punted to the back, relegated to the bench.

I'd like to see more OpsDev happening. So let's look at a handful of things Ansible can help you do with your day-to-day Ops life.

  • Repurposing A Toy Computer From The 1990s

    Our more youthful readers are fairly likely to have owned some incarnation of a VTech educational computer. From the mid-1980s and right up to the present day, VTech has been producing vaguely laptop shaped gadgets aimed at teaching everything from basic reading skills all the way up to world history. Hallmarks of these devices include a miserable monochrome LCD, and unpleasant membrane keyboard, and as [HotKey] found, occasionally a proper Z80 processor. [...] After more than a year of tinkering and talking to other hackers in the Z80 scene, [HotKey] has made some impressive headway. He’s not only created a custom cartridge that lets him load new code and connect to external devices, but he’s also added support for a few VTech machines to z88dk so that others can start writing their own C code for these machines. So far he’s created some very promising proof of concept programs such as a MIDI controller and serial terminal, but ultimately he hopes to create a DOS or CP/M like operating system that will elevate these vintage machines from simple toys to legitimate multi-purpose computers.
