In this podcast we dive into the age-old producer and consumer problem, talked about the different aspects of it (what does it really solve?), and explain the difference between throughput vs latency. Lastly we discuss the ThreadPoolExecutor and how to fine tune it for your particular project needs!

In this episode we describe the most used collections in the Java framework, and how can they help you out. We also talk about maps (and the importance of immutable keys), and the equals/hashcode contract (why are these anyways? :). Finally we discuss how to safely access these collections/maps from different threads (and cover the check-then-act operations in maps). If you used a map, or ever got a ConcurrentModificationException, this episode is for you!

This episode goes deep into memory in Java, understanding how memory leaks happen (and how to solve them!), also how to design to avoid memory leaks, weak and soft references, and how the Garbage collector works (Eden, Tenured, Perm). This podcast will help everyone that needs to take care of a memory leak!

Kudos to VisualVM and VisualGC!
