About the coexistence of pieces with different licenses

For a publicly distributed copyright-able work (as opposed to a mere bundle) to legally include, combine and extend varyingly licensed copyrighted resources by third parties, it is required that said resources aren't just free (i.e. libre) as for permitting usage, modification and distribution; but also that their licenses are compatible with one another (i.e. that one can possibly satisfy them all simultaneously).

Might compatibility be achieved, the larger work must be distributed under unified terms that satisfy all the criteria; for instance, by presenting a set of licenses to choose from if many of them survived the compatibility process.

Therefore, even though isacdaavid.info may be composed of files with different licenses, the work as a whole only abides by a subset (usually a single one) of them. That's the license you should observe when distributing and extending isacdaavid.info. It is still possible to pick up the parts and use them separately with their original licenses.

isacdaavid.info includes, extends, or simply offers the option to extend third party works under the following licenses (details are given below):

These licenses can be freely mixed, with the combination released as CC-BY-SA 4.0. Thus, isacdaavid.info as a whole is licensed under the Creative Commons Attribution-ShareAlike 4.0 International License.
