Today I will start a new brand of posts: “Honey! It’s not what it looks like”. The idea here is to present some concepts about terms commonly used, but sometime misunderstood or just not clear enough to give a common ground for a good conversation. Some confusion could raise when we use those kind of … Read More
Well this kind of question is quite common (unless you don’t care at all about the subject).

Everyone knows that float point numbers are far from been precise. In fact they are as precise as any other number, the problem is that they work in a different base (2 instead of 10).

Yes that is true, the GOF Design Pattern book is not the bible of the OO design patterns; it is just The Book of Genesis, the beginning but it is far away of the end. In fact new problems, causes new common ways to solve them and at a final stage new patterns. In a … Read More
Back to the middle of 2003 I have spent sometime reading and investigating how to use Java in the factory field, based on some standards like Fieldbus, Profibus, Supervisory Systems and so on.

Yesterday we “finally” deployed in production a version of the software that took quite a long time to go.

When we find ourselves developing software for “internal” costumers is quite easy to forget that your … Read More
These last two weeks I have read many articles about Document-Oriented databases, for sure they have potential and also it is true that it is not the panacea to all our problems.
