Architecture Weekly #157 - 11th December 2023
Welcome to the new week! I’m feeling like a surgeon in recent days. And that may also happen to you! Who knew that changing the connection management in the storage library would be a delicate thing to do? I did, but it’s still an intriguing feeling. Event Sourcing is hard, complicated and impractical. At least, so they say. I think that's the contrary. It can be straightforward, practical and helpful. Ok, but who's right? You may find out in my recent webinar: I showed how to build a simple but close to real-world application, explaining the foundational aspects of Event Sourcing one by one. I used C# and Marten as an example, but I tried to make it accessible even if you’re not a .NET developer. If you’re interested in the more advanced stuff, check out an excellent write-up on the bi-temporal aspects of looking at the events’ timeline. It shows nicely and practically how to analyse data from the perspective of where it happened and when it became effective. This is critical for business reports like budgeting and analysing the state of the systems as in, as of, etc. As architects, we also need to include a lot of bi-temporal thinking into our considerations. We need to learn from the past, observe current trends and make predictions. I brought you some food for thought for all those aspects. Future: Present: Past: I like Werner Vogels’ takes; they are usually nuanced, and even if he tries to convey his agenda, it’s balanced by explaining his biases. He predicts that:
Read the whole article to get a nuanced view. I’m happy that Werner Vogels, one of our industry thought leaders, is so optimistic about upcoming changes. Still, I’m not so positive. Yet, it’s good that one person who makes the strategic impact sees FemTech, cultural differences and education evolution as important aspects. It might not improve upcoming tech changes, but we already have too many tech bros, ignoring those crucial aspects. So the more people think about that, the more likely some positive change will happen. Check also a talk by Trond Hjorteland showing why we should centre our system design around humans: I’m showing a lot of case studies in the newsletter releases, as I believe it’s important to know how far we can go. I’m trying to show case studies both from Big Techs and smaller companies. Knowing how big tech are solving their issues gives us a horizon, smaller, something to relate to and build our paths. We need to remember that we will probably never get close to the scale that those Big Techs have. Thus, if we try to follow their practices blindly, we will probably end up with overengineering and too much ceremony. Did you wear your older siblings' clothes? Did you like it? Nah? That's how you will feel if you blindly try to apply best practices from big tech. Still, it’s worth taking cautious inspiration. Read more on tech case studies: And organisations: Remember also that there are things that, even in big tech, are coming more from trends and financial practices than rationality. For instance, their stock will increase when they hire, which means they’re growing. When laying people off, because they overhired, they’re also winning because they’re making necessary hard decisions. And their stocks will also increase: Sometimes, they just make not aligned business decisions: And those hard decisions, are usually not hard for decision-makers, but those that were laid off. From the other topic, I loved Kent Beck's last article: I’m against so-called emergent design. I haven’t seen yet a proper design emerge. I like that TDD is about a quick feedback loop about your design, crafting your API and seeing how it works.

It already contains the exclusive Discord channel for subscribers (and my GitHub sponsors), monthly webinars, etc. It is a vibrant space for knowledge sharing. Don’t wait to be a part of it! p.s.2. Ukraine is still under brutal Russian invasion. A lot of Ukrainian people are hurt, without shelter and need help. You can help in various ways, for instance, directly helping refugees, spreading awareness, and putting pressure on your local government or companies. You can also support Ukraine by donating, e.g. to the Ukraine humanitarian organisation, Ambulances for Ukraine or Red Cross. ArchitectureAI
