JVM Languages

Following on from the previous post on operator overloading I’m going to be looking at Implicit Conversions, and how we can combine them to with operator overloading to do some really neat things, including one way of creating a multi-parameter conversion. So what’s an “Implicit Conversion” when it’s at home? So lets start with some basic Scala syntax, if you’ve ...

I love me some Scala. Actually, since it’s now my day job, I love it all the time. It combines the short, expressiveness that I prized in Python with a rich library base (thanks Java) and the compiler checking that I have come to depend upon in a statically typed language. I don’t care what some people say. I recognize ...

Those who know me are aware that I’ve been following play framework, and actively taking part of it’s community, for a couple of years. Playframework 2.0 is right around the corner, and it’s core is programmed in Scala, so it’s a wonderful opportunity to give this object-oriented / functional hybrid beast a try… Like many others, I will pick a ...

Groovy is an object-oriented programming language for the Java platform and can be used as a scripting language. Most of us but instead of using Groovy alone, we use Grails (web framework based on Groovy) for developing web applications. But Groovy can be used standalone for developing your internal tools. Let me explain why Groovy scripts have simplified our development ...

Let’s imagine, your system is deployed on one node, where you running actors that literally draining out the resources. You want to add some more nodes running actors of the same type, to balance the load across the cluster. Ideally, when you add a new node to existing infrastructure you neither have to create proxies to remote actors on the ...

For over a full year now, I’ve been looking into Scala. I have heard many people talk about it passionately and it just got me interested. Also a lot of big companies are investing in this new language. I just figured I had to check it out. In my 4 years of Java programming, I’ve learned the Java EE stack, ...

I have found it both interesting and rewarding to learn a new programming language or major framework on a roughly yearly basis. If forced to self-identify with any single programming language, it would be Java. However, over the years, I’ve used C and C++ fairly extensively and have used and learned enough to be dangerous about several other languages including ...

I have been working with Scala for more than five years. In those five years, I’ve seen Scala evolve and seen the ecosystem and community evolve. An attribute of Scala is that the Scala compiler generates fragile byte-code. This means that all the code in an executable (JAR or WAR) must be compiled with the same library and compiler versions. ...

Preface This is part 12 of tutorials for first-time programmers getting into Scala. Other posts are on this blog, and you can get links to those and other resources on the links page of the Computational Linguistics course I’m creating these for. Additionally you can find this and other tutorial series on the JCG Java Tutorials page. This post isn’t so ...
