Reviewing a book draft and remembering what @martinfowler told us when we were writing #eip:
Writing a book, whenever you think you're almost done, that's when the real work starts.

[Alberto Brandolini @ziobrando]

A Bounded Context is not a purely logical (language consistency, unity of purpose) or physical (code separation, deployment unit) concept. It's an obligation to maintain integrity between those views. #DDDesign

Even just a few years ago, "software architecture" was not a topic that people were interested in ... "because agile". Times are changing?

[Kamil Grzybek @kamgrzybek]

In your system you should have 3 types of events:
1. Private, domain events (sth important occured in your domain)
2. Private, persisted events (based on 1, for later async processing)
3. Public,integration events (based on 2, to integrate with another contexts, part of contract)

[Kamil Grzybek @kamgrzybek]

Related to my last tweet - the difference between event types.

One problem with "mostly right" takes on my dissertation is when they see the trees but not the forest. REST isn't about APIs; it's about system interaction for network-based apps. But the constraints were also designed to induce a uniform network-based API (URI+HTTP+HTML+etc).

Happy that our paper on a move operation for CRDT trees has finally been accepted by IEEE TPDS! We've spent over two years trying to get this thing published, eventually successful on the sixth submission… https://t.co/sFQgNaF8cq
