Reference Architecture

This week we are going full blast at the SOA Reference Architecture.

The key to getting this right (IMO) is to make sure that the actions that people take in 'real life' are properly taken into account in the context of SOA. I.e., SOA is a means for people to act 'at-a-distance', at least indirectly.

So, we are looking at the roles that people play, the authority that a role brings and so on. Pretty interesting stuff.

The other intriguing thing is that I (at least) am learning more about UML. In particular, views and viewpoints. A little scary to think that the entire RA might be captured as a series of views and viewpoints.

Comments Should be Meaningless

This is something of a counterintuitive idea: Comments should be meaningless What, I hear you ask, are you talking about? Comments should communicate to the reader! At least that is the received conventional wisdom handed does over the last few centuries (decades at least). Well, certainly, if you are programming in Assembler, or C, then yes, comments should convey meaning because the programming language cannot So, conversely, as a comment on the programming language itself, anytime the programmer feels the imperative to write a meaningful comment it is because the language is not able to convey the intent of the programmer. I have already noticed that I write far fewer comments in my Java programs than in my C programs. That is because Java is able to capture more of my meaning and comments would be superfluous. So, if a language were able to capture all of my intentions, I would never need to write a comment. Hence the title of this blog.

Minimum Viable Product

When was the last time you complained about the food in a restaurant? I thought so. Most people will complain if they are offended by the quality or service; but if the food and/or service is just underwhelming then they won't complain, they will simply not return to the restaurant. The same applies to software products, or to products of any kind. You will only get negative feedback from customers if they care enough to make the effort. In the meantime you are both losing out on opportunities and failing your core professional obligation. Minimum Viable Product speaks to a desire to make your customers design your product for you. But, to me, it represents a combination of an implicit insult and negligence. The insult is implicit in the term minimum. The image is one of laziness and contempt: just throw some mud on the wall and see if it sticks. Who cares about whether it meets a real need, or whether the customer is actually served. The negligence is more subtle but, in the end,

Hook, Line and Sinker

It is well documented that people’s #1 fear is speaking in public ! Effective and efficient public speaking is a whole topic in its own right; but a few simple tips might help to both improve your effectiveness and help to reduce the anxiety. You may be called on to talk about your work at very short notice; or you may have a week’s notice; and you may be required to give a formal slide show or just a brief verbal update. Many, if not most of the issues, are the same. The Hook Newspaper editors call the first paragraph of an article ‘the hook’. Its meant to hook you into reading the rest of the piece. On the other hand, the classical ‘say what you are going to say, say it, and say what you said’ approach gives people plenty of time to switch off. The hook may be playful, it may be controversial, but it must communicate why the listener should pay attention. The Line Its a conversation! Even if no one says anything they are listening and thinking; and maybe replying to you in their head
