The Domains

The building blocks required to achieve success in a business domain and differentiate the company from its competitors:  Core domains : The interesting problems. These are the in-house activities the company is performing differently from its competitors and from which it gains its competitive advantage.  Generic domains : The solved problems. These are the things all companies are doing in the same way. There is no room or need for innovation here; rather than creating in-house implementations, it’s more cost-effective to adopt \ buy existing solutions. Supporting domains: The problems with obvious solutions. These are the activities the company likely has to implement in-house or outsourced, but that do not provide any competitive advantage. Domain experts are subject matter experts who know all the intricacies of the business that we are going to model and implement in code. In other words, domain experts are knowledge authorities in the software’s business domain. T

The Sweetness at the End

A million times more bits enter our heads than consciousness perceives. Consciousness lags behind what we call reality. It takes half a second to become conscious of something, though that is not how we perceive it. Outside our conscious awareness, an advanced illusion rearranges events in time. Our consciousness lags behind because it has to present us with a picture of the surrounding world that is relevant. But it is precisely a picture of the surrounding world it presents us with, not a picture of all the superb work the brain does. The sequence is: sensation, simulation, experience. But it is not relevant to know about the simulation, so that is left out of our experience, which consists of an edited sensation that we experience as unedited. What we

The Tree of Talking

A tree shows how the writer compresses a lot of information into very little information. Exformation is generated. Exformation is the discarded information, everything we do not actually write but have in our heads when and before we write anything at all. Information is the measurable, demonstrable utterances we actually come out with. Little amount of information is transferred as text and is received unchanged. The reader associates outward and up the tree, obtaining all the associations needed to understand the text. [The User Illusion: Cutting Consciousness Down to Size (1999) by Tor Norretranders]

Some People

Vera was good-looking, not at all stupid, quick at learning, was well brought up, and had a pleasant voice; what she said was true and appropriate, yet, strange to say, everyone — the visitors and countess alike — turned to look at her as if wondering why she had said it, and they all felt awkward. [Leo Tolstoy (1869), War and Peace]
