All around me architects and business managers are beginning to mandate that internal software applications be built (and sometimes rebuilt) as microservices so that we can reuse them and compose applications more quickly. I do admit that the idea of a curated catalog of well designed microservices is attractive. Contrary to all the buzz that this is a new approach and will produce huge efficiencies, there is a lot of history that points to serious barriers to a microservice economy. Microservices are Not New What is being referred to as microservices today is......

Last week I spent way too much time integrating Apache Wicket and Google Guice. Yikes! The most difficult part for me was getting the initialization to happen in the right order.

The information below was delivered to one of my programmers as direction for how to implement a rather big change in an existing software product that I sell. I thought it was potentially useful to a broader audience, so I’m posting it here: …The rest of this is rather complicated to explain online. I’ll do my best.

This is a more segmented approach than I have seen in the past, and I can see some benefits and drawbacks to it. Based on other......
