For the relaunch of my personal website, I used the awesome Hugo static website generator, and for a shorter leadtime, extended it with two custom Hugo Shortcodes I use frequently.

Having used legacy PHP-based CMS solutions such as Wordpress or Typo3 for a long time, I finally switched back to a static website generator, for various reasons. In this article, I want to outline a setup which makes it possible to treat distributed website development as clean as any other software, including versioning and continous deployment.

Given an overall systems architecture or infrastructure which gets the “IoT” box ticket, the will probably be a place where data transfer and size will come into account, for instance if constrained devices are using a potentially unreliable or expensive connection, such as a cellular data connection. For instance, an enbedded monitoring device which serves the purpose of delivering real-time telemetry to the core system of a car manufacturer will quickly come to a point where…

Thank you very much for attending my first conference talk on JCON which was, besides many talks at smaller user groups, actually my first big conference talk.

This is a companion article for my first talk at the Go User Group “Gophers” Aachen about Protocol Buffers and coupling Go services with Java.

In various test cases, primarily those covering components that interact with the filesystem and use filesystem entitites for a convention-based operation, it perfectly makes sense to provide a filesystem resource in an expected state to assess the component-under-test’s behavior.

Designing and implementing distributed systems, both customer-faced or just datacrunching farms, one is soon required to determine performance impacts and possible bottlenecks.

Let the code speak for itself.

While I was preparing the deployment of a private pet project, I got the impression that my approach had significant room for improvement in the front-facing reverse-proxy department. The project consists of a scalable set of microservices serving several tasks in the backend, tied together with a message bus protocol.

My company gave away a couple of abandoned spare devices previously used for evaluation purposes. So, I got hands on a dreamplug, a socket-plugin sized mini computer (ARM based) with decent power, low energy consumption, integrated dual Ethernet, WiFi, Bluetooth and, most important, an optical audio output - in other words: a Raspberry PI with a housing and the IO I was missing. The digital output was the primary reason for using it as an addon to my stereo.

As the mayority of the Alexa Skill developer tutorials are focusing on Node or Python, I would like to highlight the Java way and point out some things that I missed in the official trainings and some things that I would personally have solved differently.

After various encounters and two projects which employed MQTT, I thought it was a good idea to write a summary about my experiences and my point of view. As my new job is very close to the IoT and Industry 4.0 sector, it did not take much time to encounter the hype. Once upon a time

When I completed my compiler design studies, I felt it was not appropriate for me to give my exercise projects any fancy names and put them on Github. With this in mind, I was used to question any new language which came out of nowhere and wait for a number of readings on my technology radar before considering to deal with it.

Calling myself a passionate cyclist and having some time off left after coming back from a bike tour to Denmark, I decided to ride three climbs which are used frequently on the Tour de France: Mont Ventoux, Col de Galibier, and Alpe d’Huez, with a break on the Cote d’Azur. This is my report about the Giant of Provence, Mont Ventoux.

During the evaluation period of two new projects with an expected lifespan of 10 years, free from any legacy constraints, I recently had to decide on a method to provide data persistency.
