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...)
Programmers have a head start over the rest of humanity in leading happy, meaningful lives. If you have not yet reached complete enlightenment, I encourage you to sign up and invest 30 minutes listening to this call. It might improve your life.
I’ll be going to the UKOUG Tech 14 conference in Liverpool in December to give one of my favorite presentations: “APEX or ADF? From Requirements to Tool Choice”. I’m also leading the Development Tools roundtable, which is always lively at the UKOUG conference. If you want to discuss your options as a developer in the Oracle world, UKOUG Tech 14 is the place to be.
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...)
One of the great things about working in IT is that you can often win an argument simply by being right. Not because of who you are or because you are more eloquent than others, but because the facts support your position. Almost every IT person I have ever met respects facts.
In order to win arguments this way, you of course need some facts to work with. And that’s where too many people fail. (more...)
Each year at the annual Oracle ACE Director briefing, I look around at the laptops my fellow ACE Directors are carrying. More and more of them are MacBooks – I think we were up to around 50% last year.
That makes it all the more puzzling that the installation guide for the latest version of Oracle JDeveloper (12.1.3) does not mention OS X installs at all. The 12.1.2 version had sections (more...)
Everybody knows they need good dental hygiene – daily brushing and flossing, regular checkups at the dentist. But many IT professionals don’t realize they need good IT hygiene as well – regular maintenance, security patches, etc.
If you don’t practice good IT hygiene, you will experience pain down the line. I’d like to help you avoid that – get in touch.
My carpenter has been putting in a new floor in a room in my house, and I noticed that he makes some of his tools as he goes along.
It’s not that he doesn’t have a hammer and a cordless electric screwdriver. But every once in a while, he needs to move, align or support something in a way that his standard tools do not support. So he immediately builds an ad-hoc tool out of (more...)
Packt Publishing has a “buy one, get two” offer that runs until Wednesday. If you don’t have my ADF books, this would be a great opportunity to buy my new book Oracle ADF Enterprise Application Development – Made Simple: Second Edition and get a free copy of Developing Web Applications with Oracle ADF Essentials (or the other way around
AMIS and Oracle are pulling out all the stops – Oracle is flying in their top UX talent to speak, AMIS has lined up some of their experienced consultants, and they’ve even invited a few outside experts (like me).
I’ll be co-presenting with Killian Evers (more...)
Again and again, I’ve seen significant decisions made based on defective reasoning. One of the most common errors is the fallacy of the converse – the belief that if A leads to B, and B happened, then A must have happened.
This fails to take account of all the other things that might have caused B. But many people don’t see this because these other explanations are beyond their cognitive horizon.
