In this article I’m going to give a brief overview of some techniques to build ’least privilege’ roles in AWS. This assumes a basic knowledge of AWS and Identity and Access Management. It uses the (at time of writing) newly announced features in the AWS IAM Access Analyser I’ll be demoing the techniques using a project built on The Serverless Framework but you don’t need to know anything about how this framework works to follow the article - it is just used to demonstrate the concepts.

I’ve been updating some of my .NET projects recently (read more about this in Modernising .NET projects for .NET Core and beyond!). In one of these projects I have to work with the Windows Registry - which can be quite painful, particularly if you want to make your code unit test friendly. In this article I’m going to introduce a simple approach to make testing the registry a little easier. If you are just interested in the code and not so much the story behind it, you can skip straight to the project at github.

The world of .NET is going through a transformation. The .NET Framework is reaching end of life, .NET Core is an increasingly feature rich and robust platform to develop solutions which target Linux, MacOS, embedded devices, containers and more. There’s also the .NET Standard. But what does this mean for .NET Framework projects? In this article I’ll describe how to modernise your .NET Framework projects for .NET Core, the .NET Standard and .

In this article I’ll share some observations, tips and tricks for the Linux Foundation’s “Certified Kubernetes Administrator certification and exam. I’ve been operating Kubernetes in multiple environments for a few years now. I thought this would be an easy certification to get, but I was surprised by how hard it was! I took this exam without doing any formal training, I mostly focused on the areas of the curriculum which I knew I was a little weak at.

In this article we’ll look at a few simple techniques which can really supercharge your Java project and make them much easier to work with! Semantic Versioning Why Does This Matter? The Semantic Versioning Specification Using Semantic Versions The Challenge of Semantic Versions Conventional Commits Time for Magic Enforcing Conventional Commits with Git Hooks How the Hook Works Creating the Initial Release Go Forth And DevOps The Gradle Version That’s It tl;dr If you know the concepts, then just jump straight to my fork of standard-version at github.

I have rebuilt my “Effective Shell” series as an online book - it’s available now on: https://effective-shell.com The whole site is built from a GitHub repo at github.com/dwmkerr/effective-shell. It is open for contributions, changes, issues and suggestions. I’ve also added a comment section to each page to get input. To keep the material as accessible as possible, I have added a new section for beginners, to help anyone who has not used a shell before.

With a little bit of free time for a change, I decided to finally migrate my blog from Ghost to a static site generator. I’ve been putting this off because it’s one of those things that I knew would take longer than I’d expect, and to be honest, it it ain’t broke, then don’t fix it. So, Why Bother? Reason 1 - I write in vim Reason 2 - I backup on GitHub Reason 3 - My workflow sucks for images Reason 4 - I have two sources of truth Reason 5 - I want to allow people to contribute Reason 6 - I don’t want to manage a server Reason 7 - I need to learn how do this Reason 8 - Static Sites are Fast and Simple Picking a Generator Jekyll Gatsby Hugo The Migration Process Automating Build and Deploy Changing Front Matter to YAML Normalising Newlines Restructuring the Content Bringing the images to the posts Was It Worth It?

In this chapter, we’ll take a look at the various different types of shell commands that exist and how this can affect your work. By the end of this chapter, you might even be able to make sense of the horrifying and perfectly syntactically valid code below: which $(where $(what $(whence $(whereis who)))) Part 1: Navigating the Command Line Part 2: Become a Clipboard Gymnast Part 3: Getting Help Part 4: Moving Around Part 5: Interlude - Understanding the Shell Part 6: Everything You Don’t Need to Know About Job Control Part 7: The Subtleties of Shell Commands What Are Commands?

Job control is a feature of most shells, which is generally not particularly intuitive to work with. However, knowing the basics can help prevent you from getting yourself into a tangle, and can from time to time make certain tasks a little easier.
