Web Development Tools
As a test, I re-created the HRSystem application as described in the tutorial Developing Rich Web Applications With Oracle ADF. It's more than your basic Hello World application.

Scala is an object oriented and a functional programming language. If you already know Java or C# you will find Scala an easy to learn and a powerful one. Most of the new features that were added in C# (comparing with Java) exist as well, and apart of enjoying the power of OOP you will also get to enjoy the power of Functional Programming.
There are many advantages for using Scala. However, the...

Ian Bogost's recent article Flash is Not a Right highlights some new aspects of the debate about Apple's iPhoneOS development restrictions. I have a different opinion.
I understand Ian's pain as a teacher. Programmers who aren't curious, don't like to explore varied languages and paradigms, are doomed to rank-and-file roles. But this is secondary. The purpose of computing is to serve the needs of...

It seems that when we develop a trait (that includes both abstract and concrete methods) in Scala and compile it, the outcome includes two jave byte code files. The first includes the definition of an interface with an identical name to the one we gave our trait. The abstract methods that interface includes are the same methods defined in our trait. The other file includes the definition of a...

Back in the early 80ies "of the past millenium" (As journalists call it these days - don't you feel as old as I do when reading that phrase? For me it is just "Childhood" and feels not so far ago. At least not a Millenium ago.), when I was a young boy, I teached myself BASIC programming on my father's Sinclair ZX Spectrum 48K and started coding small arcade games (what else...
