Making the tough decisions early make the other decisions easier
To do agile you should be standing on a firm foundation
Stability != Static

YAGNI?  not extremely!
Fainting Ignorance :Don’t Play dumb! If you know some stuff celebrate that you know it and put a peg in the ground.
It is ok to know stuff, it is alright.

Crosswords :: Should Architecture Rewrite be Avoided?

Filed under: Architecture, Refactoring — Sadache @ 7:08 pm

As it gets more and more difficult to adapt software to new demands, the temptation to rebuild it in order to update the architecture grows stronger. For this risky undertaking it is essential to choose the right strategy. Several authors provide insights into advantages and disadvantages of different possible options in terms of cost, technical complexity and potential commercial risk.

Insights: You don’t need your DSL to be English-like

Filed under: Agile Programming, Domain Driven Design, DSL, Useability — Sadache @ 7:49 pm

There is a widespread opinion that a good DSL has to be English-like. Dave Thomas advocates against such approach asserting that DSL are not about getting as close as possible to natural languages and that having this as a guiding principle of DSL design can be rather detrimental. He also highlights what he believes is important in DSL design and provides some examples of successful DSL.

Programming Languages: More Powerful with less Freedom?

Filed under: Agile Programming, Functional Programming, Haskell — Sadache @ 6:46 pm

In quest for more power, languages are often grown with new features. While it provides programmer with more freedom, does this actually achieve more power? Reg Braithwaite believes that this is not necessarily true and argues that it is possible to render language more powerful yet limiting options offered to programmers.

Obsev:: Mutability is addictive like drugs, Mutation can become a cancer!

Filed under: Architecture, C#, Refactoring, Domain Driven Design, Functional Programming, Paradigm Oriented Programming Language, Haskell, Mutability, Decipline — Sadache @ 11:51 pm

This is really crazy!

The first time I got introduced to mutation, I had a bad feeling. How can x:=x+1 be logical at all?

It felt so unnatural, scary, or maybe like a hack. Then, because of society constrains, I got to forget the bad feeling about that. Well, my mind started to tolerate with counter-logic logic. And that is how I became an enterprise developer. I am not sure how proud I am with this title anyway. I feel that tolerating and accepting the counter-logic logic is one, and most important one, of the prerequisite to this title.

Crosswords:: Testing and Recoverability: Object Oriented vs. Functional Programming Languages

Filed under: Agile Programming, Functional Programming — Sadache @ 12:53 am

In his latest blog post, Michael Feathers’ argued that object oriented programming languages offer some built-in features that facilitate testing and are therefore more recovery friendly than functional languages. Proponents of functional languages expressed strong disagreement with this statement, which provoked a very passionate debate in the blog community.

On JAOO 2007 I could, with the help of Floyd, organize a debate between Bob Martin and James Coplien about TDD and DbC. This is the most interesting debate about the subject I’ve ever heard of. A lot of things I wanted to say have been said here. And I am proud to announce it :)

Communicating Intent through Idiom and Paradigm Selection

Filed under: Agile Programming, Functional Programming, Paradigm Oriented Programming Language — Sadache @ 8:44 pm

What about using idioms and programming conventions as signals to achieve more readability and expressiveness? This is what Reg Braithwaite advocates for, suggesting that syntax or even paradigm choices can be a means to communicate the intent.

Refex:: Does code become better as it approaches English?

Filed under: Architecture, Agile Programming, DSL — Sadache @ 5:50 pm

Achieving readability and expressiveness by writing English-like code is one of the trends on the rise in today’s industry. Michael Feathers advocates for considering other alternatives that can be instrumental for improving code expressiveness. He argues that in some circumstances symbolic approach is more appropriate than the narrative one and highlights some trades-offs between them.
