AI has no body

AI has no body New Year in The Netherlands has always had a problematic association for me because of an experience I had as a small child. My parents and I stayed at my grandmother’s for the occasion, and I was put to bed on New Year’s Eve being to young to be able to stay up. At midnight hell broke loose. The room in the apartment of my grandmother where I slept looked out over the sports grounds where the main fireworks event took place each year. It was the most terrifying thing...

Your brain does not process information and it is not a computer | Aeon Essays

Your brain does not process information, retrieve knowledge or store memories. In short: your brain is not a computer. Written by Robert Epstein, a senior research psychologist at the American Institute for Behavioral Research and Technology in California. He is the author of 15 books, and the former editor-in-chief of Psychology Today. No matter how hard they try, brain scientists and cognitive psychologists will never find a copy of Beethoven’s 5th Symphony in the brain – or copies of words,...

von Neumann, revisited

PETER BELANGER/INTEL Intel’s Bold Plan to Reinvent Computer Memory (and Keep It a Secret) John von Neumann (during the Manhattan project, 1940-1945). Public domain, Link We all read John von Neumann’s groundbreaking paper “First Draft of a Report on the EDVAC” back when it was published in 1945, did we not (just joking)? You should. And read it well, because not many people did (I know of no-one). OK, I admit that some of the mathematics is above me as well, but one thing stuck with me: there...

Computers are not about technology

The main problem of the technological focus of computers is precisely that: that it is seen as a technology. Because of that, technologically savvy people are attracted to it, and arising problems in all areas of life are discussed within a technological mindset. Our current society is very much coloured by technology. Johan Huizinga, a Dutch historian and one of the founders of modern cultural history, pointed out the dangers of this focus in several works of cultural criticism during the rise...

The Live Domain

Conway’s Game of Life Prompted by an old discussion on Reddit (link expired), kicked off by the question: “Please explain OOP to me in the language of a five-year old”, I found myself musing on the reasons computing seems to stay stuck in the Middle Ages. It is not for lack of great minds or vision. In fact, I have the impression, the problem seems to be that nobody ever seems to read anything. Why is that? Is there some kind of unspoken consensus that, since we are in the area...

The ArchiMate metamodel

This article introduces a complete, navigable and clickable representation of the ArchiMate metamodel standard. The model is created using UML. This is not because I wanted to translate ArchiMate into UML, but because UML should be well-suited to define a language such as ArchiMate in. And after all, also the standard itself defines its metamodel using something that looks like UML. In fact I think the ArchiMate forum should decide to formally specify ArchiMate in UML and “own” the...

Grass-roots architecture governance

Introduction Most people I work with think of architecture governance as something imposed upon the populace from above. They see architects operating from a kind of control tower: architectural guidelines and rules, constantly fighting to uphold the norms they themselves concocted. I do not think that will work in the long run. For me, architecture governance works much better when it self-organises from the roots. For that, a simple model has been created that I would like to share with...

Business-centred ArchiMate

Introduction This article attempts to reconcile the ArchiMate modelling language with Business-Centred design principles, principles I strongly advocate. ArchiMate as a language (or, as some would say, a grammar, since a rigid definition of its semantics does not exist) is very “traditional” in the sense that: it is very IT-centric it explicitly invites the modeller to use a data-centric world view it does not exploit the power of distributed systems (for example as it should be doing with...

Requirements Management and TOGAF

… or any Enterprise Architecture framework. As you may know TOGAF puts Requirements Management in the centre of its ADM method: TOGAF ADM As one might expect, since this aspect of enterprise architecture is so prominently placed, it will be given a lot of attention in the TOGAF standard, right? Not so. The number of pages dedicated to this phase in the ADM in the 9.1 version of TOGAF is 8 pages. Preliminary 12 Architecture Vision  10 Business Architecture  14 Information Systems...

SmallSim

SmallSim is a business simulation tool. It helps building complex business models, and then execute these models. With SmallSim you create executable models. The important differentiating characteristic of SmallSim is that SmallSim is not only executable, but it executes inside a full-fledged simulation environment. These business models can be the centre of a business-centred software architecture for enterprise systems (also called the Business Domain or Domain Component). Using...
