  • Impressions of the first JVMCON (Feb 1, 2018)

    Last Tuesday was the first edition of JVMCON. This conference has a special programme committee: its audience. When the Call for Papers closed, everyone who had a ticket could see the submitted papers. Only, they could not see who submitted the paper - which let them focus on the papers themselves. Out of almost 180 papers, they had to select 13…

  • I upgraded to Java 9 - Part II (Jan 23, 2018)

    A few weeks ago, I wrote about migrating an existing Spring-application to Java 9. When I finished, two things remained to be investigated:

Many of them promise you (to some extend) ultimate flexibility and endless possibilities. My preference is for “lean and mean” approaches where I can pick the building blocks that I need. In the long run, that offers more flexibility. After all, you could replace building blocks. Having small building blocks makes it less tempting to put any kind of business logic in such a gateway. Doing that must sooner or later lead to some kind of vendor lock-in.
