When Pointers Attack (or How to Save 26-36 bytes of Memory in a Week)
You may have noticed, I’m currently running experiments where I have a lot of small things. So many, that I computed I had an overhead of 16 bytes apiece (12 bytes per state and 4 bytes for a pointer to it), and was too [...]
Memory-Efficiency in Java
I like to generate state-spaces. I generate a lot of them. And I have made the code efficient enough that I can generate very large ones. Normally, when you code, using hundreds or even thousands of bytes for an object is no issue, but [...]
Memory Leaks in Java Code
I’m working on some Java code I’ve inherited. I’m doing some speed improvements in critical places, and to test my improvements, I need test cases to compare different implementations. Unfortunately, manually generating test cases is way too time consuming (need need thousands and generating [...]
