The Unfinished Conversation Concept in Maemo 5 (posted by Fabien Villard)

Maemo 5 Maemo is the framework used in Nokia Internet tablets since the N770, and today in the N900 phone which combines a cellular phone and an Internet tablet. Though I’m very found of this little thing that starts to look like the Star Trek communicator I wanted when I was a kid (except for [...]

PxFAQ – Why are CRUD operations generaly located in Set Business Logical Machines? (posted by Fabien Villard)

Related questions: Why separate Elementary and Set machines/operations? Would it be interesting to add a CRUD Business Logical Machine next to the Elementary and Set ones? It is clear that we are considering things in the Logical Aspect and that no justifications will come from Technical Aspect. First shot CRUD operations are not high level [...]

Praxeme and Complex Systems (posted by YvesC)

This is a follow-up to a conversation that started during the meeting of the “Collège des contributeurs” last week. Although I do not have the time to post a proper discussion, I’ll start with a few headlines to “get the ball rolling” : start a discussion. Hence I’ll use an “outine style” and leave the [...]

PxFAQ: What is this strange thing called Logical Aspect? (posted by Fabien Villard)

Related questions: Can we use upstream models directly in implementations? What is the interest of the Logical Aspect if I want to build an SOA? We put important efforts in upstream aspects, can we make some savings in the logical one? The logical aspect is sometimes considered useless and we hear some people willing to [...]

PxFAQ: What are the services we *need*? (posted by Fabien Villard)

Related questions: How to find them? How to assert that they are the right ones? How to respect the decoupling principle? By giving clear procedures to deduce services from business inputs, Praxeme solves the problem of finding the right services in the only available way: changing intuition only procedures to analytic thinking. By structuring precisely [...]

BPM and SOA (posted by Fabien Villard)

We see more and more attention on relations between SOA and other parts of IT, with important questions like the one raised in the following blog post: http://www.jpmorgenthal.com/morgenthal/?p=103. Relations between SOA and BPM is like relations between bass guitar and drums. They live separately and have their own rules, but they can produce great music [...]

Security is a strategic concern (posted by Fabien Villard)

Here is an interesting point of view on security business today from an IBM Security Strategist: http://www.networkworld.com/news/2009/081709-8-dirty-secrets-of-the.html Among the eight points some are tightly related to enterprise strategy and enterprise architecture. Points 2, 6 and 7 focus on external concerns, regulations and security product vendors, but  others may be summarized like this: what do I [...]

Get out of the immaturity model (part 2) (posted by Fabien Villard)

[Part 1] Here are some points to focus on to try to get out of the immaturity model. Some are obvious. Some may sound like weird ideas. But do not underestimate culture: obvious points may not be obvious for everyone and weird things may well be weird only for those who see them for the [...]

Get out of the immaturity model (part 1) (posted by Fabien Villard)

“IT is a young discipline” syndrome For as long as I have worked in IT I have heard this dogmatic explanation. It is used for all sorts of issues ranging from hardware failures to heavily bugged software including huge and astonishingly complex IT solutions without strong relations with business problems. Each time, the maturity idea [...]

Movies errors, a wish list (posted by Fabien Villard)

Lately I re-read a list of errors about computers [fr+en] (sorry for English readers, items are in English but comments are in French) found in movies. It’s not exactly the first time I’ve read such a list and it’s always amusing to see a collection of problems movie makers do about our domain, but this [...]
