Deutsch When programming in Java, it is kind of part of the language to write classes with attributes and equip these attributes with „getters“ and „setters“. You could do otherwise, but you just don’t. But some criticism is of course allowed. Even if it only applies to the design of future languages or to minor …

I participated online in the conference „Functional Scala 2020“ in London. That it was in London had mostly one relevance, which was the time zone. There was no physical location and all talks were done online. An interesting idea was a virtual location. It consisted of rooms and we could move a dot representing ourselves …

When we create new objects, we are basically confronted with the need to provide at least one construction pattern. Of course depending on the language we have more or less three ways to go that are commonly available. Traditionally in OO it was mandatory to write setters and getters. In C++ or Java they really …

Ironically Scala at first drew my interest, because I discovered that about ten years ago there was no really good understanding of how to do a good multithreading concept for Perl 6. I thought exploring how they do it in Scala, where it was already known to be good at that time, would give a …

In December 2019 I attended the conference Functional Scala in London which was initiated and managed by John de Goes. See Skillsmatter about what happened to Scala Exchange. Of course a large part of the conference was related to ZIO, which seems to be a part of the eco system surrounding Scala with a lot …

The company Skillsmatter in London has been put „under administration“ and basically stopped its operations. The web site seems to suggest, that everything is still ok, but that is not the case and I have heard so from several sources. The owner Wendy Devolder writes on Twitter and on Linkedin. Or here are some more …

Scala Days had a tenth anniversary in 2019. It is an annual conference about Scala, which I like to visit, when possible. There is some confusion as to what is meant: Where this the 9th, 10th or 11th Scala Days? Where the first Scala Days 9, 10 or 11 years ago? The truth is, that …
In many programming languages we are urged to define methods hashCode, equals and toString. They are named like this in Java and in many JVM languages or they use similar names. Some languages like Perl and Scala provide decent mechanisms for the language to figure these out itself, which we do most of the time …

In March 2019 I have visited ScalaUA in Kiev. It was interesting. I attended the following talks: Thinking Functionally by John A. De Goes Streaming data processing with Apache Spark by Roksolana Diachuk Theory of Constraints in Programming: Beyond Problem-Solving by Anatolii Kmetiuk Video Q&A session with Martin Odersky by Martin Odersky and Jon Pretty …
There is now also an implementation of Flashsort in Scala. In order to solve the requirement of sorting part of an array that is needed as part of flashsort, an heapsort implementation in Scala that can be constrained to a part of an array has been included as well. Heapsort was chosen, because it can …
