One more year Apiumhub sponsors JBcnConf and gives a talk there. In this article we would like to highlight the best things of the event and key facts that make a difference in the industry!

Apiumhub sponsors JbcnConf

Let’s start with Apiumhub collaboration with BarcelonaJug community, we co-organize events in Barcelona and help each other to promote them in our communities.

BarcelonaJug organizes JbcnConf – an annual event in Barcelona and we strongly support this initiative because everything starting from location to speakers is on a very high level.

This year we couldn’t miss this chance to get reunited with the Java community and got a stand in CCIB to have face-to-face conversations with developers, speakers and companies that are eager to grow in the Java field. It was an absolutely amazing experience because we met a lot of like-minded people, who also got interested in Apiumhub software development services and Global Software Architecture Summit, which will take place in the same venue in October.

Severn Everett – Backend developer at Apiumhub gives a talk about The Exceptional Performance of Kotlin at JbcnConf

Severn Everett – backend expert in Apiumhub gave a talk about “The Exceptional Performance of Kotlin”. There is a saying”don’t use exceptions as flow control”, but why? In 2014 Aleksey Shipilëv published “The Exceptional Performance of Lil’ Exception”, an excellent article on the performance characteristics of the exception system in Java and how different exception handling strategies in various scenarios work out to demonstrate why the adagio exists. Since then, the Kotlin programming language has exploded in popularity, and this language introduces new options for handling exceptions, for example inline classes and sealed classes. With the help of the Java Microbenchmark Harness, this presentation explores the benefits, drawbacks, and performance characteristics of various exception handling strategies that can be employed using these Kotlin features.
