The Pragmatic Programmer – Review / Summary Notes.

I recently finished The Pragmatic Programmer, to be completely honest this had been the 3rd attempt to read it, although the book is good and well worth the read, I had unfortunetly learnt most of the lessons the hard way on my own over the last decade or so of being a software developer, so I found often myself easily ...

You are working on that fresh project and you see a bad piece of code somewhere. The wrong way to approach it is “nah, that’s someone else’s code, I’m not doing anything about it”, “I don’t have time to fix that – I have other tasks”, “I’ll surely break things if I change this”.

More on Creating Stubs for Legacy Code – Testing Techniques 7

In my last blog, I talked about dealing with the badly behaved untestable(1) SitePropertiesManager class and how to create stubs by extracting an interface. But what happens when you don’t have access to the source code of the legacy class because it’s locked away inside a third party JAR file? The answer is one of those things that you really don’t ...

Java Recursion basics

For those who don’t know what recursion is (and like a good laugh), click on this link: Google search: Recursion and click on the “did you mean…” item. Hopefully you’ve finally figured out that recursion is anything that refers to itself (if not, then you may be stuck browsing google forever trying to find out what recursion is!). A fairly ...
