Useful Hugo Shortcodes for PDF lists and Image galleries

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. Automatic Gallery The template I am temporarily using for the launch phase already contains basic gallery support with the primary aim of styling based on Fancybox, but it lacked automatic serving of a directory as a gallery. What I knew was that I wanted to drop my galleries under /static/galleries/{name}, as I heavily prefer the convention-over-configuration maxime.

Data Serialization Frameworks in Java

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 JSON-Encoding might exceed the computing power required for the actual job.

Using Google Protocol Buffers as Glue between Java and Golang

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 a distributed system it is required to go beyond communication by shared memory, and even cross technology borders. This is nothing uncommon, it is more or less standard for a contemporary system to be designed as a distributed, interlinked collection of software modules which are not necessarily implemented in the same technology or even computer architecture.

A brief history of persistence in software engineering

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. Starting from scratch in 2015 prompts the architect with quite a lot of interesting solutions, especially because the more and more mature solutions which are not strictly pursuing the Relational Database approach. In this article I will summarize my personal “history” of how I dealt with persistency and which way I am going to choose.
