One common theme in discussions of persistence is to be critical of the traditional SQL databases, which have been successfully used in business applications for decades. As alternative to these SQL databases, often so called NoSQL solutions are advocated. NoSQL, essentially, dramatically simplifies the kind of data, which can be
Exceptions are a necessary evil of most software development endeavours. As much as we would like to design applications, which are equivalent to mathematical functions 'give me one input and always I will trustfully return you the same output', the real world IOExceptions, OutOfMemoryExceptions, DivideByZeroExceptions and their various
Formatting JavaDoc using plain HTML can be a troublesome and time-intensive experience. Today I installed the JDocEditor plugin for eclipse, which allows editing JavaDoc in eclipse using a small rich text editor.

Although an SVN server is possibly a fixed anchor in dynamic and distributed development efforts, even these servers might have to be relocated from time to time. Surprisingly, this can be done quite swiftly, even in complex set ups, for instance an eclipse workspace comprised of dozens of projects stored
There has been not little critizim of the slow progress made in the core of Java. Java 6 has been released on the 11th of December 2006 (!). Java 7 saw the light of the day almost five years later this July. Competing languages, most notably C# in Microsofts .NET environment
