Java Design Patterns

Based on Christopher Alexander's pattern language, design patterns in software allow us to apply reusable patterns to common use cases and scenarios in software development instead of having to reinvent the proverbial wheel each time we're facing similar problems. If you'd like to brush up on design patterns in the context of Java as a programming language, Java Design Patterns has you covered. Java Design Patterns is a website "showcasing Java-based design patterns, principles, and code snippets". For a more general, language-independent overview ...

Aarron Walter – Returning to Your Maker Roots @ beyond tellerrand Düsseldorf 2022

To me - with many of the speakers (Geri Coady, Jude Pullen, Cabeza Patata, among others) talking about change and experiments - Aarron Walter's idea of reconsidering (which inspired the Re:considering podcast co-hosted by Aarron) what's truly important to you has been the overarching theme of this year's beyond tellerrand Düsseldorf:

I see numbers

Metaphors play a vital role in how human beings make sense of the world. The ways in which we view and describe both the world around us and abstract thoughts often are inherently metaphorical. When relating to time, for example, we often use spatial metaphors such as "to look forward to", "time moving forward", or "to turn back time". For some though, relating to time in terms of spatial concepts and relations can take on quite a literal meaning. I've always visualised numbers, ...

Opinion-driven Design: Simplicity Over Flexibility

Software developer Brent Roose recently wrote a blog post on what he calls "opinion-driven design". His point his that while a mindset of "high configurability and flexibility" is undoubtedly common when it comes to the development of software frameworks and libraries, it ultimately is also misguided in most cases. In an attempt to both accommodate every possible use case and to remain in control (also known as the "Not invented here" (NIH) syndrome), framework developers tend to favour flexibility at the expense of ...

CloudMapper: An AWS Visualisation Tool

CloudMapper is an AWS visualisation tool that's highly useful for getting an overview of your AWS infrastructure and network setup. Depending on the number of services, instances, VPCs, and subnets used, getting lost is quite easy, especially when considering that out-of-the-box with AWS there's no single unified console from which to get an overview of your deployed resources but rather a multitude of consoles, one for each AWS service. Therefore, keeping track of your infrastructure and keeping your costs in check can be ...

2020 in Review

May you live in interesting times. - claimed to be a translation of a traditional Chinese curse - Usually I refrain from writing one of those end-of-the-year reviews because they often amount to little more than self-involved navel-gazing (been there, done that ...). However, 2020 was a truly interesting, extraordinary and in many ways remarkable year. So, here goes, navel-gazing and all ... In December 2019 (or thereabouts) what we today know as COVID-19 or the Coronavirus pandemic started to spread causing a global crisis ...
