[2/2] The Philosophy of Architecture - Barry O'Reilly - NDC Oslo 2024 (Category Architecture)

Continue. philosophy and architecture I'm going to talk to you about Barry's concept for dealing with complexity.

1. Substance philosophy The Western approach to philosophy focuses on things and is like an intellectual prison. But there's a way.
2. Process philosophy pointy

• Identity is about becoming
• Nothing is truly static
• Including our phenomena - every time we look at a static thing we contemplate it differently So the question is, how do we get knowledge? In the old approach, we have observations, fixing the properties of objects, categorizing them, launching experiments if we are not sure, and then understanding the true essence of things. But for architecture, the author suggests thinking about the concept of an architectural walk, when we work on one topic from different angles to get an idea of the problem area in which we plan to develop something.

3. From here the author draws The concept of criticalityIt's about being able to withstand conditions that weren't in the specification. In fact, this property described by the author is more like survival. (survivability). The author says that biological systems have such properties, but there is such a fork in software engineering that

• SDE (software developemnent engineers) They are more focused on the correctness of systems, that is, the system does what it is asked to do. Architects aim more for survivability when the system adapts to conditions and continues to operate.
• And that's two big differences.

Next, the author shows how the key concepts inherent in the creation of the system break down with changes. This example is based on the concept of "Customer", which is first a natural person, then a legal entity is added, and then foreign legal entities. This leads to a change in architecture, or rather a paradigm shift. (Like Thomas Kuhn in the book.Structure of scientific revolutions"). And here comes the concept of residue, which is based on the approach of the author, which he outlined in a scientific article.Residuality Theory, random simulation, and attractor networksAnd I told you in a great talk, an introduction to this theory, which I'm already talking about. told. The main point is that the residue according to the author of the theory

• Is a unit of software architecture Is a container for components Describes architecture for alternative timelines Every architecture consists of residues.
• They happen in sequence.
• We're finding them. We accept hypotheses through random modeling.
• We have significant results.

As a result, the old approach was about linear thinking, and the new approach was about non-standard thinking and the ability to think outside of rigid logical structures. Architects must be able to use both types of thinking to successfully design and develop software. (But even I find it hard to think outside the box.). Architects should take responsibility for their philosophy of architecture and not accept what industry and education impose on them. Reading books on a wide range of topics, not just your specialty, can help with this.

P.S. I recommend reading books about systems and critical thinking, which I have already read. wrote earlier.
