So here is my (currently growing) collection of stuff, including writings and notes.
Unless otherwise noted, artworks (i.e. music, images) are licensed under the Creative Commons Attribution license, documents under the GNU Free Documentation Licence, and code under the 2-clause BSD licence.
Note: If, like me, you're unwilling to wade through the legalese, basically this means that for artworks, you can do anything you want with them (share, modify, or even sell them!), provided that you give me proper credit; for documents, this means that you may share, modify, or sell them, provided that you reproduce the licence and grant the same rights to whoever receives them; for code, this means that you may use the code for any purpose, as long as it retains the licence and you promise not to sue me if things go bad:)About me
