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.

Java Language Features Introduced From Versions 8 Through 17

The Java programming language and the Java Virtual Machine (JVM) are known for being very stable and favouring compatibility over new language-level features. This focus on stability arguably is one of the reasons why Java is so popular with larger companies, particularly those of the enterprise variety, where reliability, maintainability and a long-term outlook are key and typically more important than the latest and greatest features. However, starting in 2017, with the Java release cycle changed to rapid 6-months iterations, from the previous ...

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 ...

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 ...

Admiral Grace Hopper Explains the Nanosecond

Grace Hopper was a brilliant computer scientist, who - among numerous other achievements throughout her career in mathematics and computer science, the military, and the at the time nascent software business - can be credited with having had a pivotal role in the development of the business programming language COBOL (which quite deservedly got her the nickname Grandma COBOL and which in turn gave rise to enterprise software and the enterprise software industry) This is her visually explaining what a nanosecond ...

German COVID-19 Tracing App Available Now

Earlier today, the highly anticipated COVID-19 tracing app for Germany, called Corona-Warn-App, has been released. The iOS version is available on the App Store. The Android version can be downloaded at Google Play. The Corona-Warn-App is based on the DP3T (Decentralized Privacy-Preserving Proximity Tracing) architecture and the joint specification by Apple and Google for privacy-preserving exposure notification, which implements this architecture as an API for official public health providers to draw upon. The app is developed and published as open source under the Apache ...

No-code, Low-code, Some Code and Everything In-between

CTO-for-hire (through Freeman Clarke) Alex Hudson recently wrote an article about what he terms "The 'No Code' Delusion": That so-called no-code and low-code tools will replace bespoke business software development entirely, no trained software developers required anymore. In a nutshell, it's the old pipe dream of just having to write a specification (in this case a visual one) and having the actual code write itself, the fallacy here of course being that the code is the final product rather than the specification ...

Konrad Zuse: Not the most correct but the least complicated theories find practical application.

Not the most correct but the least complicated theories find practical application. - Konrad Zuse A translated quote from one of the inventors of computers and modern computer science I read last year under a bust of Zuse near Kleiner Tiergarten in Berlin this statement is more relevant today than ever. In software development in particular we often attempt to design solutions that cover each and every possible use case - however unlikely or even virtually non-existent that use case might be. ...

JSON Web Tokens: Downsides, Best Practices and Secure and Robust Alternatives

JSON Web Tokens (JWTs) nowadays are commonly used for transmitting authentication data in web applications, especially those exhibiting the widespread client-server architecture where you have a fat client / single-page application written in JavaScript as a front-end and a back-end server providing REST endpoints for use by that front-end client. However, while common there are good arguments against this practice. In a nutshell, JWT often are used for storing session data such user authorization and authentication information although they aren't particularly well-suited to ...
