Fresnel 0.75.6-preview is out! 🚀 Why did it take so long? We spent the summer dogfooding with a major client. Complicated subdomain, which would normally take months to design 🗓. Fresnel let us build a deep prototype in... 10 days😎! Go check it out! nuget.org/packages/Enviv…

Domain discovery involves identifying all the elements that make up the domain. Domain modelling involves pulling all the elements apart and putting them all together again in a form that works for you.

Domain Driven Design Europe 2024 will be held at our familiar spot, The Meervaart in Amsterdam. You can expect an inspiring atmosphere and lots of talks and hands-on labs. See you there? Save the date and get your tickets early now. buff.ly/3QkTjZV

Great evening with the folks from .NET Oxford last night at Atlassian Williams Racing HQ. Learned quite a bit, and Nick Chapsas did a great job of demoing .NET Aspire. Now I know what the f*** it is!

"Fresnel Domain Model Explorer" v0.80.1-preview is out! And now it uses .NET 8! More UI enhancements ('doodle' mode has a more 'grid paper sketch' feel ✏), and other fixes. Download: nuget.org/packages/Enviv… Here's the "Shopping Cart" model in action (github.com/Envivo-Softwar…):

I've worked in/with quite a few cultures, but never took the time to really learn the 'rules of engagement'. Fascinating write up. 👍

There 2 kinds of domain models. Only one makes sense. In Domain-Driven Design, you move the business logic to the domain. Your domain objects contain rich behavior and encapsulate rules. The important parts of your business logic and rules all live in one place. This

just ran across this old rebuttal about how the antidote to requirements shift is to lock everything down tight to the nth decimal place: nope, in general, then answer is better communication. Watch:

Spot on.

Great thread. I need to get this on a wall!

People tend to look at budgets the wrong way, IMO. The cost of software development per unit time (your engineering-dept. budget) is trivial to figure. Number of people * salary * load. There. You're done. You'll pay that out even if everybody sits around playing Canasta all day.
