The times when Java was available on almost every desktop are long gone but you can still distribute your desktop applications written in Java in a user friendly way. Since the release of OpenJDK and OpenJFX 9 we can benefit from the JVMs modularization efforts and easily build executables with a bundled JVM trimmed to the needs of our application. In this article we will show you how we ported our small desktop app called PDF Decorator initially to OpenJDK 11 and used tools like jlink and jpackage to start distributing our app without requiring any third party software on our clients machines.

Problem: we want queries to our entities to eagerly fetch only the fields that we need in the given context (for example to show in a specific UI data table). Requirement: our solution must be able to accept dynamic filter compositions. Possible solutions: Named Entity Graphs from the JPA standard or Projections mechanism from Spring Data.

In the past months we could hear many controversies surrounding an upcoming coin developed by FutureNet called FuturoCoin. FutureNet is a social network and Multi Level Marketing (MLM) platform. Most of the cryto-community didn't take them seriously and ware expecting another DasCoin - a coin which had little do to with the term 'cryptocurrency' but was heavily marketed as such using MLM. Both FutureNet and the creators of DasCoin (Netleaders) are under investigation by the Polish government under the suspicion of being a ponzi-scheme. The fact that FutureNet promoted their FuturoCoin without even publishing a whitepaper also didn't help. Now that they finally have one and also published their source code we can see what this coin really is.
