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.

RunKit: Instant, reproducible JavaScript playgrounds

I'm a huge proponent of the idea that programming tools should directly interact with coding and provide immediate, responsive feedback to changes. RunKit is such a tool that offers a comprehensive JavaScript / Node.js prototyping environment. The service supplies you with instant, sandboxed Node.js instances called "notebooks" that allow you to experiment with the whole gamut of NPM modules. Moreover, "from graphs and maps to low level hexadecimal inspectors" RunKit offers data visualisations for immediate visual feedback. Once done you can showcase your ... Read more

Deploying Spring Boot applications as old-fashioned WAR files

Spring Boot is an opinionated convention-over-configuration framework for creating stand-alone Spring-based Java applications. Its objective is to provide you with a preselected best practice choice of libraries (both from the Spring platform and by third parties) for a given task, e.g. building a web application that connects to a database and provides REST resources creating a scheduled batch task that exports and aggregates data from various data sources providing an API that connects to SOAP Web Services It both helps you with getting started quickly and ...

The Blockchain’s Potential to Change Business And Society

I'm fascinated by the blockchain and in particular the potential it holds for decentralising and disintermediating business processes. Though certainly intriguing as well I'm not so much interested in the implications the blockchain and Bitcoin, the cryptocurrency that's built on the blockchain, have for payment and financial systems. My area of interest rather is with how the blockchain enables us to rethink business processes that until now required some sort of third-party intermediary to establish trust between parties. Think of transactions in ... Read more

Spring Batch Resources: Batch Processing, ETL And Data Conversion

ETL (extract, transform, load) processes, data processing, exporting data from one business system (ERP, CRM, accounting etc.) and importing it into another are common requirements in enterprise IT. So much so that the ability to export and import data often is the key feature of enterprise software. Spring Batch is a toolkit in the context of the widely used Spring framework that allows you to define and run batch jobs and data processing pipelines. Spring Batch provides features such as: data export / ... Read more

Matt Ranney @ GOTO 2016: What I Wish I Had Known Before Scaling Uber to 1000 Services

At the GOTO Chicago 2016 enterprise software conference Matt Ranney, chief systems architect at Uber and co-founder of Voxer gave a presentation on what they learned from adopting microservices on a massive scale at Uber: "To Keep up with Uber's growth, we've embraced microservices in a big way. This has led to an explosion of new services, crossing over 1,000 production services in early March 2016. Along the way we've learned a lot [ ... ]" Now you probably aren't Uber but the ...

Mockito 2 now available

Last week version 2.1.0 of the Mockito testing framework for Java has been released. For more information on this latest iteration check out this page. As the name suggests, Mockito allows you to mock object behaviour during unit tests. When writing unit tests you only want to test a particular unit's behaviour (hence the name). Depending on the programming language used such a unit might be a function, a procedure or - most commonly in today's object-oriented programming environments - a ... Read more

Less Is More

What's true for design in general certainly is true for software design in particular: Less is more - or paraphrasing Dieter Rams - "Write less software in order to write better software." A few weeks ago I read this interesting article by web accessibility consultant Heydon Pickering. In this blog post he argues that the only foolproof way of writing performant web applications is to write less code. Sure, all that fancy minification, transpiling, JIT / AoT compilation and optimisation stuff might ... Read more

Daily Standup Meetings: Anti-patterns And What to Do About Them

Daily standup meetings are a mainstay of agile software development methods, such as XP, Kanban (which used to be an inventory control system having originated at Toyota) and Scrum, of course. Given that agile development methods are by far the most dominant ones in the software industry today, it should come as no surprise that daily standup meetings are a common feature of software development processes these days. These meetings basically serve the purpose of informing everyone on the team about these 3 ... Read more

Follow-up on “Accounting in 2016”

Two months ago, I wrote an article on how accounting in 2016 still is a manual and tedious process. What made me write this article in the first place was the problem that I couldn't automatically get the bank account statements for my business account into my accounting software because my bank's online banking service and my accounting software have incompatible import / export file formats and neither exposes a public API for facilitating communication between and automation of accounting software ...
