Er der nogen der har erfaring med udskiftning eller reparation af Tesla Model S batteri (Model 85D) i Danmark?

@boyney123 I would also add that it’s not all internal events that are relevant to publish as external events

What are internal vs external events in event-driven architectures? I like to group services and events by domains. Depending on where my events live, depends on what goes inside my events, how they are managed, and the cognitive load required when dealing with them. What are internal events? Think of internal events as events raised within a bounded context. The relationship of these events are completely different to events that are raised for external/other contexts. You may see examples of teams owning particular context/services, and using messages/events within these services. These teams are close to the events, so management of these events might seem easier. For example if the team is the only one consuming the events/messages making changes to the events becomes more flexible as no external party is using these events. Private/internal events can also expose implementation details, the domain has a clearer understanding of the events. What are public/integration events? Think of these events as events raised for integration, events consumed by other domains, these have more strict rules. Making changes to the events are more risky. You might not know who is consuming them. Are you going to break downstream consumers? Exposing implementation/domain information might be an anti-pattern. Do your consumers of these events really need to know about your database implementation details, or your domains ubiquitous language? Probably not. Use language/contracts that can be understood, that are clear so consumers can integrate with them without needing too much domain information.

I saw 2 main ways to structure service. 🅰 /services -/MyService1 --/IService1.cs --/Service1.cs -/MyService2 --/IService2.cs --/Service12cs 🅱 /serices -/interfaces --/IService1.cs --/IService2cs -/implementations --/Service1.cs --/Service2cs What's your choice?

@seldon_raven Everytime (EU standard) 🥳

In ~4 years of driving an EV I have never touched a CCS charger. Have you?

@patrickmagee I'd say that's nearly 100% of companies, and yes, this is the problem. If each company dedicated a few hours once a month to fixing the libraries they depend on, or donating money, the problem would be solved.

@stilkov @jeppec Let me record the updated URL here because, hey, this is still the best article I know on the subject :-) cramonblog.wordpress.com/2014/02/25/mic…

Jeg forstår ikke Evida’s brug af queueit for aflæsning af forbrug. Der er tale om en hurtig validering af 2 nøgler ,der skal matche (simpel læse model), og derefter kan de gemme aflæsningen i en kø der stille, roligt og asynkront kan opdatere deres bagvedliggende systemer 🤕

If you use Wikipedia, you've seen pop-ups like this. If you're like me, you may have donated as a result. Wikipedia is an amazing website, and the appeals seem heartfelt. But I've now learnt the money isn't going where I thought...

"Events are actions..." Events are *not* actions and don't necessarily represent future actions. A command represents the potential for future action. An event is a factual record that an action took place. Consumers should translate events to commands to react to the events.

@kelseyhightower Many retailers have been building up inventories at a rate that far exceeded their current sales in the hope that people would buy when items were in stock. Some financial analysts predicted the current status long ago and they predict that prices soon will go down substantially

-= The Myth That Renewables Need Weeks Of Battery Storage =- 🧵 This one has been circling a lot recently, so I might as well nip it in the bud. It goes like this: "To save the planet with renewables, you need weeks of battery storage to keep the lights on. Impossible!"

As event-driven architecture continues to gain in popularity, I feel the need to remind folks about the risks of coupling caused by sharing raw business data via events, often occurring with noun-oriented services (like User, Product, Order, etc). youtube.com/watch?v=Fuac__…
