... no, don't tell me you like Perl. Because you don't. You never did. It does horrible things. It makes your code look like... Perl made heavy use of operator overloading and used operators for a variety of things. A similar tendency can be seen in C++ and Scala. See also people comparing the two. … Continue reading Why Everyone Hates Operator Overloading

Typesafe’s Slick is Not About SQL
We have stumbled upon an interesting thread on the Typesafe SLICK user group where Slick was compared to jOOQ. In that thread, Christopher Vogt has made a couple of interesting statements. But let us have a look at the broader context, first. Unifying Stuff Ever since the proclamation of UDDI or RUP, we may think that … Continue reading Typesafe’s Slick is Not About SQL
Top 10 Ceylon Language Features I Wish We Had In Java
What does one do when Hibernate is "finished" and feature complete and one needs new challenges? Right. One creates a new JVM language called Ceylon. On November 12, 2013, Ceylon 1.0.0 was finally released and we congratulate the whole team at Red Hat for their achievements in what looks like a very promising new JVM … Continue reading Top 10 Ceylon Language Features I Wish We Had In Java
Will Another Play-Style Framework Make its Way to Java?
I've just discovered the Ninja Web Framework. This one isn't "yet another framework", it's actually heavily based on the very popular Play Framework ideas. It seems to provide a substitute for the latter, since Zenexity and Typesafe have formed an alliance to further support Play primarily in the Scala ecosystem. Some people may feel that this … Continue reading Will Another Play-Style Framework Make its Way to Java?
Fast File System Operations with Xtend, Lambdas, and ThreadPools
Recently, I've blogged about 10 Subtle Best Practices when Coding Java, and I have mentioned that you should start writing SAMs (Single Abstract Method) now, in order to be prepared for Java 8. But there's another language gem out there, which comes in handy every once in a while, and that's Eclipse Xtend. Xtend is a … Continue reading Fast File System Operations with Xtend, Lambdas, and ThreadPools

Twitter and the JVM
Here's an interesting read about Twitter and why they had chosen to migrate to the JVM for scalability. A must-read for everyone working on Java, Scala, or other JVM languages: http://www.forbes.com/sites/oracle/2013/08/01/theres-java-in-your-tweets/
Duck Typing in Scala: Structural Typing
Scala goes very far with its loads of features improving the JVM world. Sometimes, a bit too far, maybe. But this feature here is just plain awesome! Typesafe duck typing! An example: def quacker(duck: {def quack(value: String): String}) { println (duck.quack("Quack")) } The above quacker method accepts any "duck" that can quack. Read the full … Continue reading Duck Typing in Scala: Structural Typing
SLICK, integrating SQL into Scala
Now it's official - even if version numbers are still preceded by a "zero" major release: SLICK has been publicly announced by Typesafe: http://blog.typesafe.com/introducing-slick http://finance.yahoo.com/news/typesafe-announces-scala-language-integrated-100000262.html http://java.dzone.com/articles/slicker-scala-stack-qa-martin SLICK stands for Scala Language-Integrated Connection Kit, which is more or less the Scala equivalent for LINQ-to-SQL. Note that I say LINQ-to-SQL, not LINQ in general, as Scala already has … Continue reading SLICK, integrating SQL into Scala
When will we have LINQ in Java?
LINQ is one of Microsoft's .NET Framework's most distinct language features. When it was first introduced to languages such as C#, it required heavy changes to the language specification. Yet, this addition was extremely powerful and probably unequalled by other languages / platforms, such as Java, Scala, etc. Granted, Scala has integrated XML in a similar fashion into … Continue reading When will we have LINQ in Java?
