Your applications contain 20-30% dead code that is never executed. Not just commented-out code that programmers have left in “just in case”, but routines never called, branches never executed and screens never displayed.
The cost of software maintenance depends on the size of the code base, but systems with dead code are more expensive to maintain. This is because every time a developer comes across a dead piece of code, he becomes unsure: “I wonder (more...)

I’m proud to be one of the Oracle ACE Directors. Watch the video for some viewpoints on the Oracle ACE program from both Oracle and other Oracle ACEs.
Not all documentation is created equal. Too much time is spent on formal design documents that are immediately outdated, and too little is spent on writing code comments.
Make sure your process requires and rewards good code comments. And make sure your architecture diagrams are kept up-to-date.

If you want to discuss your options as a developer in the Oracle world, UKOUG Tech 14 is the place to be.
APEX or ADF? From Requirements to Tool Choice
Quick, how many different Web Service specifications are there?
- less than 20
- between 20 and 40
- more than 40
I was in doubt whether the answer would be 1) or 2) – after all, there is a lot of WS-* stuff. Turns out the answer is 3) – there are currently 50 web service specifications.
A technology with 50 specifications is unlearnable. The basics of web services is simple and useful, but the IT industry (more...)
I was recently advising a transition project where a customer was switching support and maintenance supplier. This means that one organization must take over a system that has been maintained by another organization for a number of years.
A lot of information is lost in these transitions because knowledge of the problem domain has been accumulated in the heads of developers over many years. This loss cannot realistically be mitigated.
But sometimes, specific information about (more...)
