It is an interesting idea to generate colorful images using or music. In both areas Clojure seems to be quite attractive. Not having explored the music side, I did find the idea of creating images fun and inspiring. It also shows us something about the functions we are working with, if we learn to read …
When exploring the usage of databases for persistence, the easiest case is a database that does only SELECT. We can cache as much as we like and it is more or less the functional immutable world brought to the database. For working on fixed data and analyzing data this can sometimes be useful. Usually our …

The idea is, that we have data that is obtained or calculated to give us on demand as much of it as we request. But it is not necessarily initially present. This concept is quite common in the functional world, where we in a way hide the deprecated concept of state in such structures, by …

Java has always not just been a language, but it brought us libraries and frameworks. Some of them proved to be bad ideas, some become hyped without having any obvious advantages, but some were really good. In the JEE-stack, messaging (JMS) was included pretty much from the beginning. In those days, when Java belonged to …
I have just visited Clojure Exchange. Since it had only one track, there is no point in listing which talks I have attended, since this can easily be seen on the web page of the conference. It was interesting and there were many great talks and I also met great people among the other participants.
As already written in Devoxx 2016 I visited Devoxx in Antwerp 2016. Hot topics where Java 9 and the functional features of Java 8. But there was a wide range of talks.
