Do We Have To Synchronize Everything?
Evaluation of ThreadSafe made me think about the Java Memory Model and its implications on threaded programs.
Is The Double-Check Idiom Really Really Fixed?
The double-check idiom is a way to reduce lock contention for a lazy initialized thread safe class. Unfortunately it used not to work. Luckily it was fixed. ...
Java Polymorphism And equals()
How should equals() behave in case of polymorphic classes? What are the pitfalls here?
Memory leaks even with WeakReferences
A crash report arrived at my desk the other day. The system crashed because it ran out of memory. And the major memory consumer was a WeakHashMap. Very inter...
A Executor Is Not A Thread - or: Correct ThreadPoolExecutor Error Handling
Java 1.5 introduced the Executor framework. In summery: if you have some tasks and you want them to be processed in parallel by a couple of threads, then a E...
Linux Process Memory Layout
This article describes how the memory structure of each Linux process does look like.
It’s not my code! I googled it.
Actually this blog post is not about Google. And it is even not about copying code. But it is indeed about code which I did not write.

Resolving circular dependencies in C++
I stumbled several times already upon situations where I created a circular dependency between two classes. A circular dependency is a code smell.
It’s not my code! I googled it.
