What is the best way to trace down memory leaks?

The RTL uses FastMM as its memory manager. FastMM supports memory leak reporting and tracing. The native version of FastMM that is included in the RTL is a stripped down version, but it does support minimal leak reporting.

You can set the RTL's global ReportMemoryLeaksOnShutdown variable to true at run-time and FastMM will generate a basic leak report when the app is closed. For more advanced usage, you can download the full version of FastMM and add it to your app, which will replace the RTL's native version. You can then configure FastMM as desired.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
