Relearning Functional Service Design for Microservices: Uwe Friedrichsen at microXchg
The opening talk of the microXchg microservices conference was delivered by Uwe Friedrichsen, and discussed “Resilient Functional Service Design”. Key takeaways included: microservice developers should learn about fault tolerant design patterns and caching; understanding Domain-Driven Design (DDD) and modularity is vital; and aim for replaceability of components rather than reuse.

Eric Evans: DDD is Not for Perfectionists
A problem with Domain-Driven Design (DDD) since the beginning has been the too common hunt for perfect designs, but DDD is not for perfectionists. In order to stop that hunt you need to have some idea of how to create software that is well designed, yet not perfect, Eric Evans noted in his presentation at the recent DDD Europe Conference in Amsterdam.

Date and Time Formatting in Java 9 Will Get Closer to Unicode Locale Standards
Several parsing and formatting changes have been incorporated to bring the functionality closer to Unicode Locale Data Markup Language (LDML). These changes have been supervised by Stephen Colebourne, creator of the popular library JodaTime, precursor of the new java.time component in Java 8. Abiding by the Unicode standard will provide better interoperability with other non-Java systems.

NIST Guidelines Require Second Auth Factor When Using Biometrics
NIST has released a public draft of new Digital Identity Guidelines, described as “a significant update from past revisions.” The guidelines describe acceptable use of multi-factor authentication (MFA). Furthermore, when using biometric data as one authentication factor, it must be combined with something you have, and not something you know, such as a password.

The Dangers of If Statements in Domain Logic
The if statement found in most programming languages has two major roles, validating input to protect the domain from erroneous data, and for dealing with business logic inside the domain. Unfortunately, we spend too little time managing the risks from a business or domain perspective, Udi Dahan claimed in his presentation at the recent DDD Europe Conference in Amsterdam.

Bringing the Domain Back to Software Development
If you read the business press of today, you will find that the business side of the world sees IT as an impediment that holds them back. To overcome this, we need to shift focus from the machines to the domains and start reading and learning about the domains we are working in, David West noted in his presentation at the recent DDD Europe Conference in Amsterdam.

MicroProfile Becomes Eclipse MicroProfile
MicroProfile, the community initiative to provide a microservices standard for enterprise Java, has joined the Eclipse Foundation. The move is aimed at ensuring that MicroProfile remains a vendor-neutral project, and hopes to leverage the resources and momentum of the Eclipse Foundation. The decision has caused some arguments and temporarily diverted efforts from other objectives.
