I am currently dealing with a lot of libraries at work. Both third party as well as libraries written or being currently in process of being written by me. I absolutely love writing and working with libraries. Especially if they present or bring me to either a new or different approach to solve a problem. Or at least provide a different view.
Over time I noticed however that quite regulary we had to decide that we cannot use a third party library. Often it is the usual reason.

Minimal D3D11 reference implementation: An uncluttered Direct3D 11 setup + basic rendering primer and API familiarizer. Complete, runnable Windows application contained in a single function and laid out in a linear, step-by-step fashion that should be easy to follow from the code alone. ~200 LOC. No modern C++, OOP or (other) obscuring cruft. View on YouTube
Also check out Minimal D3D11 part 2, reconfigured for instanced rendering and with a smaller, tighter, simplified overall code structure, or Minimal D3D11 part 3, with shadowmapping + showcasing a range of alternative setup and rendering techniques.
