As you may know, Scala.js 1.0.0 just went final.
For end-products, the upgrade is rather simple, just bump the plugin version and fix potential compile issues. If
you’re maintaining a library, cross-building for 0.6.x and 1.0.x is still a bit tricky, but possible…

I personally like the Spring Framework and its security components, because it’s pretty full-featured and easy to use, but when it comes to Spring Security OAuth2, there’s a huge quality breakdown. In this (probably series) of blogposts, I’ll try to sum up the good, the bad, the evil and why I ended up completely dropping Spring Security OAuth2.

When it comes to importing data into a BigData infrastructure like Hadoop, Apache Spark is one of the most used tools for ETL jobs. Because input data – in this case CSV – has often invalid values, a data cleaning layer is needed.Most tasks in data cleaning are very specific and therefore need to be implemented depending on your data, but some tasks can be generalized…

Every Java library can be used in Scala, which is, for me, one of the good parts of the JVM world. But Java libs are mostly object-oriented and not functional, therefore full of side effects and somtimes “ugly” to use in Scala. But there are some approaches how to make Java libs (or their interfaces) more functional, so they can almost be used like a Scala lib.

In Java 8, the long awaited Lambda came to live, making it easy(-er) to do FP in Java. One problem I came across is, that most Java code throws checked exceptions which leads to IMHO ugly try/catch blocks in lambdas:

This is the first post of my series about functional programming in Java. There’s a lot of functional stuff one can do. Everyone knows the Java 8 Lambda expression, but with a little library support, there is way more… In this series, I’ll coder som libraries which provide functional paradigms and constructs for Java:

You may have noticed, that I had not much time to blog about something in the past months… One thing was, that we all need money, so I had to work very much. And as some of you know, I’m also studying in the evenings.

Working with the Play! Framework means working with Akka, intentionally or not. But working with Akka Actors can be
tricky, especially when it comes to dependency injection. Play! 2.4 uses Google’s
Guice for DI and of course it has the
ability to also bind Actors so an ActorRef can be injected anywhere.

As my Scala projects go on, I want to share some compiler configuration and tricks with you, which I use on many projects. Some tiny configuration options can greatly improve your code and warn you about things, you would probably never discover.

I am interested in NLP and have already some experience with Apache Solr. It’s time to dig a little in-deep regarding stemmers. First of all, I was looking for a general definition of what a stemmer is, and I found this one, which IMHO is quite good:
Read Morestemmer — an algorithm for removing inflectional and derivational endings in order to reduce word forms to a common stem
