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 Too much time is spent on formal design documents that are immediately outdated, and too little is spent on writing code comments.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

I’m often engaged with clients helping them respond to Requests for Proposals (RFPs), and there are way too many bad RFPs out there.
These bad RFPs not only specify what the customer actually needs, they also specify that the customer can possibly think he will ever need. Typical requirements are that the user must be able to add extra attributes to all entities, or that the user can dynamically change which attributes are mandatory, or (more...)

Gartner has just released another iteration of their classic “Hype Cycles.” They are up to more than 100 different topics now, but one interesting graph is one is the one for Emerging Technologies.

I want to comment on a couple of points from this graph:
- Internet of Things as peaking – completely agree. Everybody is talking about it but what do we have? An internet-connected smoke alarm.
- Big (more...)
I’m not in favour of calling books a “must-read”, but if you want to get your own book commercially published, I have to say you must read Write the Perfect Book Proposal: 10 That Sold and Why, 2nd Edition.
The main force of this book is that it explains the publishing industry from the inside: What a publisher is looking for. The authors honestly explain what the publisher will and will not do, and that (more...)
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.
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...)
I’m currently estimating the effort for a piece of software. With 20 years of experience under my belt, I don’t find estimating hard any longer. But back when I started out, I was terrified whenever I was asked to provide an estimate.
In most organizations, too much of the estimating is art and too little is science. Experienced developers can produce good, realistic estimates, but these are often treated as individual efforts and no organizational (more...)
The Lean Startup: How Today’s Entrepreneurs Use Continuous Innovation to Create Radically Successful Businesses by Eric Ries
My rating: 4 of 5 stars
This main point of this book is the principle of “failing fast.” Since you don’t know everything (and a startup knows very little), it is most efficient to quickly create some data to base decisions on.
The distinction between “vanity metrics” and real, useful metrics is illuminating. A “vanity metric” shows (more...)
I’ve been following the discussion on the new In-Memory option in the Oracle 22.214.171.124.0 database. As far as I can see, it’s very easy for a developer to start using this feature, which will cost your company $23,000 per CPU at the next Oracle license audit.
But the most interesting part is actually not the cost – it’s the discussion. Oracle expert Kevin Closson stated that there was a problem (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...)
Observing tourists around me, I’ve noticed that the regular selfie doesn’t cut it anymore. The essential travel accessory for the modern self-absorbed traveller is a selfie stick:
Of course, the whole selfie concept is the opposite of a traditional tourist snapshot: Not “see what I saw,” but “see me”. But while you are at it, why not make yourself a spectacle while you take the picture. Hence, the selfie stick.
The picture is pretty much (more...)
While we’re waiting for the mythical iWatch, Google has already released Android Wear, and the first two Android Wear watches are here. And they’re ugly.
If I’m going to wear something like that on my wrist, I need a really compelling usecase. I’m not sure that getting even more notifications and reacting 0.8 seconds faster is what I’m looking for.
When my latest Nike FuelBand eventually dies (they seem to last about (more...)
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...)
We’ve just had a leak of 900,000 national identifier numbers here in Denmark. That’s about 16% of the total population, so it’s pretty big. These numbers are unique identifiers for a person (similar to Social Security Numbers) and are a good starting point for identity theft.
Never ascribe to malice that which can adequately be explained by incompetence.
So how did these numbers leak? Through plain incompetence and lack of procedures. It (more...)
On Monday, a U.S. judge gave Microsoft control of 22 domains owned by domain hosting service No-IP.com. Microsoft intended to filter out some domains used by malware, but promptly screwed up. The result was that millions of legitimate users could not access their servers.
This will happen again and again as infrastructure moves to centralized cloud providers. What do you think will happen if the server just above yours in the server rack (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...)
Big Data is not necessarily about crunching massive amounts of data – it’s about finding unrealized value in a data set. This might be done on huge sets of billions of records, using Map/Reduce running on thousands of servers. But it might also be done at a smaller scale by a concerned citizen.
More and more data is being made available by municipalities and countries. These are typical “big data” collections: Just a bunch of (more...)
