my blog. for you.

Let’s talk digital.

I’m an independent IT consultant and entrepreneur in the Internet and software business. I’m interested in design, enterprise applications, web apps and SaaS products. I design and develop business solutions and applications. I help companies in terms of software quality and knowledge transfer, e.g. with Angular and Spring Boot.

User Experience Design Methods & Deliverables

As I previously wrote about, design and user experience (UX) design are disciplines defined and governed by rules, principles, and constraints. The highly recommended Laws of UX provides an in-depth overview of principles and best practices in UX design. Coming from a slightly more hands-on perspective, designer Fabricio Teixeira compiled a comprehensive list of UX design methods & deliverables such as service blueprints, personas, or user journeys.

A Collection of for a Improving the UX of Signup  and  Login Workflows

Independent UX designer Erik D. Kennedy recently published an article with 15 Tips for Better Signup / Login UX on Learn UI Design - a website through which he provides acclaimed courses on both UI and UX design. The article lists general suggestions such as autofocusing on the first field (i.e. the username, or rather: email, field), immediately validating form values, or making input labels clickable, as well as more specific - but no less expedient - ones like making password requirements explicit to ...

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 ...

Second-order Affordances: Design & Quantum Superposition

A few years ago, having read a thought-provoking article by Csongor Bartus I wrote about design & quantum superposition. The main idea behind this article, and my interpretation, is that - similar to a particle, which exists in a state of quantum superposition - a design doesn't exist by itself but can only ever be realised in a given context and at a specific moment through observation by a user and possibly a device that design is observed with. The gist, ... Read more

Cloud Design Patterns

In the past few months, I've been working a lot with distributed applications and more complex cloud architectures, both in terms of Stratospheric - From Zero to Production with Spring Boot and AWS (the eBook I'm currently writing together with Tom Hombergs and Philip Riecks) and client work. Microsoft's library of Cloud Design Patterns (as previously mentioned in this blog post) is a collection of cloud-related software and infrastructure design patterns that can help you with weighing up the merits of common ...

(Deutsch) Lösung für die COVID-19 Pandemie: Schnelltests als Zugangsberechtigung

Sorry, this entry is only available in German.Contrary to my usual writing habits the remainder of this post will be in German. The reason for this is that although the subject most certainly is of interest to everyone the specifics of the solution outlined in the following mostly apply to the current COVID-19 situation in Germany and my personal experience with that situation. The article therefore is mostly relevant to a German audience. If you're interested in discussing the potential for ... Read more

Five Articles on Software Quality and Design Patterns

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 Prevent It? (April 16, 2017) Less Is More ... Read more

Latency by The Radiophonic Workshop

On the 22nd of November, the electronic music pioneers of the BBC's Radiophonic Workshop (of "Doctor Who" theme music fame, amongst others) performed a unique piece of music called 'Latency', in which they make clever use of network latency to create a musical loop. Each of the musicians involved sequentially played his part in a loop. The result then was sent via the Internet to the next musician at another location, who in turn built upon what had been played until ... Read more

The Laws of UX

For a discipline that's commonly seen as being mostly fuelled by creativity rather than being particularly rule-governed, principles, maxims, and laws seem to abound in the world of design. This perception of design being about creativity, first and foremost, rather than deliberate thought is a naïve and superficial one, though. Design of course has always been about principles and constraints, Dieter Rams' famous Ten principles for good design being a particularly good example. UX designer Jon Yablonski created Laws of UX, where he ... Read more

Tools for Working With CSS Grid Layouts and Flexbox

CSS Grid Layout and CSS Flexible Box Layout, commonly known as Flexbox, are powerful techniques for implementing flexible grid and column- or row-based layouts with CSS. These two techniques enable designers and web developers to accurately and fluidly position elements and content on web pages and web applications. While Flexbox (see A Complete Guide to Flexbox by CSS-Tricks) predominantly works along a single principal dimension, called the main axis or flex direction (either row or column), and therefore essentially is a one-dimensional ...
