Preparing for Oracle OpenWorld

The big annual Oracle event is almost here – starting Sunday 28 Sep with the User Group Sunday followed by four days of presentations in around 50 tracks!

If the agenda seems a bit overwhelming, read the OTech Magazine Special OpenWorld Issue to find some of the highlights and can’t-miss sessions.

My sessions are:

  • Mastering Oracle ADF Bindings: Advanced Techniques (UGF3484). Sunday Sep 28 at 10am in Moscone South room 270
  • Starting Your Oracle Application (more...)

The Oracle ACE programme

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.

Useless Documentation

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 Too much time is spent on formal design documents that are immediately outdated, and too little is spent on writing code comments.

Useless DocumentationMake sure your process requires and rewards good code comments. And make sure your architecture diagrams are kept up-to-date.

The Spiritual Programmer

Based on my article in the latest issue of OTech Magazine, I am offering a free teleseminar (by phone or Skype) on how to live a happy, meaningful life in IT.

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.

UKOUG Tech 14 in Liverpool

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.

Are Web Service a Mistake?

Quick, how many different Web Service specifications are there?

  1. less than 20
  2. between 20 and 40
  3. 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...)

Learning It All

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...)

Being Right and Proving It

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...)

Debugging Faulty Assumptions

I wanted to install Oracle JDevelper 12.1.3 – a version that I had been eagerly awaiting. Since my primary machine is a MacBook, I wanted to install it on OS X 10.9.3.

I downloaded the generic installer and found that the install didn’t run. Since OS X had disappeared from the documentation, I assumed that I would have to fiddle around until I found a combination of JDK and OS (more...)

Development Platform Disconnect

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...)

Why you’re not getting hired

If you’re applying for permanent positions and not getting hired even though you have the skills the organizations asks for, consider whether you are proving your ability to learn new things.

I’m often talking to people who believe their 20 years of experience with technology X or Y should make them shoo-ins for a job. However, they are not getting hired.

The reason is that a modern organization can’t depend on the same skill being (more...)

Good IT hygiene

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.

Toolmaking

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...)

ADF Book Bundle – get one free!

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 ;-)

The Future of User Experience

I’m off to the Netherlands for the first and finest Oracle User Experience Event in Europe, arranged by Oracle Platinum Partner AMIS Services BV at their offices in Nieuwegein.

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...)

How many stars do you need?

The latest Michelin Guide is out, and Copenhagen added another two stars for a total of 15 of the coveted Michelin Stars across 13 restaurants.

In order to reach the exceptional level of a Michelin-starred restaurant, you need to have an absolute world-class chef. And he (almost invariably a “he”) needs a good team around him.

However, most development team does not need temperamental world-class artists. For independent software vendors, who can sell thousands of (more...)

Defective Reasoning

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.

Defective ReasoningThis 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.

I’ll talk more about (more...)

User Experience Event in the Netherlands

Together with other leading experts on User Experience from Oracle like Vice President Jeremy Ashley, Managing Partner Lonneke Dikmans from Vennster and CTO Lucas Jellema from AMIS, I’ll be speaking at the OAUX Expo in the Netherlands on March 18th.

I’m speaking on two topics:

  • How to tailor an application to your user’s needs without coding
  • How to implement a good User Experience in Oracle ADF for the cases where you do need to write (more...)

The Long Tail of Application Usage

A long tail is a distribution of some data point where a few data point have a high value, but most of the data points have a much lower value. When sorting the data points by value, there will be a large “head” and a long “tail”.

Application usage displays the “long tail” characteristic: A few screens are used much more than others.

Long tail of app usage

If you are re-developing your application, for example moving from Oracle Forms (more...)
