Opinion-driven Design: Simplicity Over Flexibility

Leider ist der Eintrag nur auf English verfügbar.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 ...

A Concise Overview of Java’s Instant, LocalDateTime, ZonedDateTime and When to Use Which

Leider ist der Eintrag nur auf English verfügbar.The authoritative answer to a question on Stack Overflow on the difference between Instant and LocalDateTime covers various classes from the Java 8 Date/Time API and how those are actually meant to be used. Names such as LocalDateTime can be misleading in that they suggest a specific locale or locality rather than any locality (as that name is intended). This, in turn, can give rise to problems with inaccurate date and time values if timezones ...

Keeping a Record of Software Architecture Decisions

Leider ist der Eintrag nur auf English verfügbar.The need for asynchronous communication in organisations has become particularly obvious since 2020, when remote work and distributed work environments rapidly became the default setting for knowledge workers. Asynchronous communication essentially means that instead of exclusively communicating objectives, goals and the way by which to achieve them in-person (i.e. synchronously with everyone involved present at the same time - whether on-site or in a virtual space such as Slack or Zoom) we try and keep ...

A Simple Yet Powerful Tool: Decision Tables

Leider ist der Eintrag nur auf English verfügbar.Decision tables are a tool for specifying which actions to perform given a number of conditions. They represent business logic in terms of rules for connecting actions with required conditions for those actions. While they might appear deceptively simple and trivial they can be a tremendously powerful tool for defining business logic and certain types of software requirements. This article on Decision Table Patterns by Hillel Wayne describes the general concept as well as patterns, ...

Cloudcraft – Cloud Architecture Diagrams and Visualisations

Leider ist der Eintrag nur auf English verfügbar.After recently having written about AWS cloud visualisation and management tools such as CloudMapper and Vantage I was made aware of yet another such tool by Sebastian Reuße: Cloudcraft allows you to not only visualise your AWS cloud architecture with beautiful as well as somewhat playful isometric infrastructure diagrams reminiscent of turn-based strategy games but also provides live connectivity with your actual AWS infrastructure and so-called "smart" components. Using these features you don't have to manually ...

Vantage – A Unified AWS Console

Leider ist der Eintrag nur auf English verfügbar.In last week's blog post I casually mentioned that out-of-the-box with AWS there's no single unified console providing you with an overview of your deployed infrastructure. Thankfully, there's Vantage - a centralized dashboard that provides you with such an overview and cost transparency across AWS regions and accounts through views, global search, and actionable insights. Up to $500 in monthly AWS spend Vantage is free. Beyond that there are Pro and Business plans at a monthly ...

CloudMapper: An AWS Visualisation Tool

Leider ist der Eintrag nur auf English verfügbar.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 ...

Beautiful Presentation of Code Snippets

Leider ist der Eintrag nur auf English verfügbar.In case you need to document and present source code and would like to do so in a visually appealing manner these tools might come in handy: Ray.so Carbon Source Code Shots With Ray.so being the most recent one and arguably also the one with the most stylish output, all of those generate decent-looking images of your source code snippets for embedding into documentation, blog posts, or eBooks, for example.

Five Articles on Software Quality and Design Patterns

Leider ist der Eintrag nur auf English verfügbar.This week I'd like to point you to five articles I previously posted on this blog and from which I think that they're as relevant as they were at the time. The first three are about general software design principles, software architecture and software quality while the final two refer to specific best practices and common design patterns for Angular: Writing Disposable Code, Not Reusable Code (November 06, 2016) What Causes Over-engineering and How Can You ...

Two Hard Things in Computer Science

Leider ist der Eintrag nur auf English verfügbar.I've always liked Jeff Atwood's variation on Phil Karlton's original quote "There are only two hard things in Computer Science: cache invalidation and naming things.": There are two hard things in computer science: cache invalidation, naming things, and off-by-one errors. However, with reactive programming these days this version by Dave Stagner probably is even more appropriate (especially since it uses zero-based numbering, which of course is the only decent way of indexing elements in a sequence ...
