What about having an official source code repository. Something that includes a multitude of example projects showing how to do certain things such as creating a directx or opengl window or an example input class or a starter entity-component framework. Code should be well written, straightforward and well documented. It should also have detailed information on getting setup on someone's machine. The goal would be to give gamedev people a great starting point and to give excellent examples on new concepts. All of these articles that are being written could have a place in the code repository so that someone could access the code. You could even have a community engine that people could contribute to. Hopefully with even community assets that could be freely used for things such as temporary placeholders or to show the functionality of say an animation system that has been added to the official source code repository. The source code repository could be broken up by language or even have separate repositories for different languages.
