JPA is the main building block in most Java projects. However, a lot of developers still use it without a deep understanding of the technology, relying mainly on applying the copy-paste methodology from StackOverflow or existing system entities. During this presentation recorded at Devoxx Poland 2017, Jakub Kubrynski consolidates knowledge about object-relational mapping. We see […]

Cloud native applications are popular these days. They promise superior reliability and almost arbitrary scalability. They follow three key principles: they are built and composed as microservices. They are packaged and distributed in containers. The containers are executed dynamically in the cloud. But which technology is best to build this kind of application? This talk […]

Everyone worries about performance but few of us have the time to truly understand it. Fortunately, our modern JVMs and CPUs are capable of some amazing performance tricks, but those same tricks only make reasoning about performance that much harder. In this talk, we’ll take a look at some surprising and often unintuitive performance problems […]

Giving food for thought this week are newbie container virtualization startup BanyanOps, who claim to have found that over 30% of official images in the Docker Hub (the central repository for  developers to pull and push container images) are riddled with “high priority security vulnerabilities.” For “non-official” images which are yet to be “explicitly verified,” […]
