These days they are looking north towards the functional territories and watch with interest as the new cities Kotlin and Ceylon are being built. Many Java inhabitants are tired of the city they live in. Not just since [ READ MORE ]

The functional breakthrough … the back door

Ever since my first encounter with Haskell in my very first week at university I have been waiting for functional programming to become more widely spread and to find acceptance in the industry.

So, today I took the time to get my IDE up [ READ MORE ]

The Bowling Game Kata in Scala

Comparing this piece of code with the Java implementation from Uncle Bob (who, no doubt, knows how to write clean Java code) I would conclude that it is more expressive [ READ MORE ]

What I like and don’t like about Scala

ThoughtWorks’ technology radar suggested to start thinking about ‘Java end of life‘ in its January 2010 issue. In following issues of the same document they list several languages that strive to be Java’s successor on the JVM. In order to lure the Java community into their net all these languages promise to run on the [ READ MORE ]
