New programming techniques and the productivity curve

Though I love learning new programming techniques and technologies, I often struggle to make them a part of my normal development processes. For example, it took years before I finally started using regular expressions on a normal basis. The reason? The productivity curve:               You may have seen a chart like this before; the ...

Using Your RDBMS for Messaging is Totally OK

Controversial database topics are a guaranteed success on reddit, because everyone has an opinion on those topics. More importantly, many people have a dogmatic opinion, which always triggers more debate than pragmatism. So, recently, I posted a link to an older article titled The Database As Queue Anti-Pattern by Mike Hadlow, and it got decent results on /r/programming: Mike’s post ...

WORA Is Better Than Native

When “Write Once Run Anywhere” is done right it can produce applications that are “better” than native apps by targeting the highest common denominator. Some would claim that native is the best approach, but that looks at existing WORA tools/communities, which mostly target cost saving. In fact, even native Android/iOS tools produce rather bad results without deep platform familiarity. Native ...

Apache Camel for Micro­service Architectures

java-interview-questions-answers

I’ve been using microservice architectures before I knew they were called so. I used to work with pipeline applications made up of isolated modules that interact with each other through queues.
