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.

Keeping database schemas up-to-date with Flyway

At least ever since Ruby on Rails' Active Record Migrations put an emphasis on keeping database schemas consistent with your software's source code both during development and in production database migration tools have become a staple in modern software development. Database migration (or database refactoring as this technique is sometimes called as well) tools allow you to apply data definition language (DDL) statements like "CREATE TABLE ..." or "ALTER ..." to databases in an automated, consistent and traceable manner instead of either ...

Learning React Native Through Responsiveness and Instant Feedback

React Native Express is an interactive guide that enables you to learn React Native right in the browser. Getting started with React Native - and React for that matter - can be quite daunting. While the framework itself isn't all that difficult to grasp there are quite a few tools like transpilers such as Babel and state management libraries like Redux which are required for getting productive with React Native. React Native Express attempts to ease you in and make that initial ...

Design & Quantum Superposition

Last year, Hungarian designer Csongor Bartus published a thought-provoking article I've only recently come across. Quantum mechanics and design are two words you don't often see juxtaposed and probably rightfully so. No, I've not gone crazy and I'm not going to go down some weird esoteric "Quantum Design" rabbit hole here. However, Csongor borrows the term superposition from quantum mechanics as a metaphor for an interesting new angle on design for the web: To cut in, let's equip all content with all states ...

Documentation and Spreadsheets with an API: GitBook and Fieldbook

Continuing on last week's post about RunKit - a Node.js prototyping environment for the browser - here are two interesting tools that make use of RunKit: GitBook is a collaborative documentation tool that allows you to create beautiful, version-controlled documentation for your software. It's used by software components like Redux and it leverages RunKit to embed live, reactive code examples in your documentation. Fieldbook is was a database creation tool thats touted as "A database with an API – as simple as a ...

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 ...

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 ...

Exporting table data in web applications as CSV or Excel files

In business applications being able to export data to Microsoft Excel is a very common requirement. In most business environments Excel is the go-to tool for business analytics and quick-and-easy data processing. Hence, being able to communicate with Excel is an essential feature for most kinds of business software. The usual approach for meeting that requirement is generating a CSV file on the server. However, while simple this approach can come with a few downsides: While CSV is a useful, accessible plain text ...

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 ...

Golan Levin on Software (as) art

I'm very interested in generative art and creative data visualisation techniques by designers and artists such as Mike Brondbjerg, Jared Tarbell and Joshua Davis. In this 2004 TED talk media artist Golan Levin showcases some of his brilliant work that uses software to generate sound and accompanying visuals:

Googling For Developers

I sometimes jokingly say: "I’m not a good programmer. I just know how to use Google effectively." When programming and being confronted with an unknown error, stack trace or a specific exception message I usually turn to Google in order to find out how other developers with similar problems previously approached these issues. While at face value this might sound easy this requires experience. You have to know enough about software development in general and the environment (language, framework, library, you name it ...
