I have published my very first project on GitHub: Allocator Builder

From the summary:

A highly composable, policy based C++ allocator based on ideas from Andrei Alexandrescu, presented at the C++ and Beyond 2013 seminar.

The background behind the idea is to compensate the main problem of ::malloc() and the other standard allocators, the separation of memory pointer and the allocated size. This makes it very difficult for all kind of allocators to handle in a fast way memory allocations and deallocations.
