Huge list of Resources
I will keep updating this throughout the workshop.
Suggestions regarding text editors
On Mac one can use the included “TextEdit” program. However, you will have to go through a little rigmarole to have it save things in “plain text” format. Go to “Format” and “Make Plain Text”; then you will have to make sure you save your files as “file.xml” as their filename, in the proper folder.
On Windows, NotePad should work more or less okay. It doesn’t have tons of features, and you will have to make sure you save in the right place. But for beginners it is fine.
On Mac, I enjoy using Textwrangler (http://www.barebones.com/products/textwrangler/download.html), though apparently the company which makes it is eventually dropping support.
Many other MBX users enjoy Sublime Text (https://www.sublimetext.com) which is not free, but which has a package for MBX enjoyment (https://packagecontrol.io/packages/MBXTools) courtesy of Dave Rosoff of The College of Idaho.
If you like the command line already, you can use nano, vim, or even (gasp) Emacs. I won’t provide any instructions for those, other than to say that as someone who didn’t grow up with a computer in my pocket, I like that nano has hints at the bottom.
LaTeX information
This is automatic in SageMathCloud.
On Windows I hear people really like MikTeX, presumably along with TeX Live.
On Mac, I strongly recommend TeXShop (http://pages.uoregon.edu/koch/texshop/obtaining.html) and MacTeX (http://www.tug.org/mactex/mactex-download.html). These are very straightforward to install. Actually, TeXShop is completely optional, but is still nice to have anyway.
On Linux you probably should install TeX Live.
General MBX resources
https://groups.google.com/forum/#!forum/mathbook-xml-support - the official support channel for MBX, at which you'll see many posts by users such as myself as well as the main developers
http://mathbook.pugetsound.edu - the official website for MBX, with a fairly extensive gallery of existing projects at the bottom to get inspired
http://mathbook.pugetsound.edu/examples/sample-article/html/ - the sample article which shows off most of the capabilities of MBX in an entertaining, if non-exhaustive, way
General open text resources
http://aimath.org/textbooks/approved-textbooks/ - the American Institute of Mathematics list of open online texts that meet a certain minimal list of approval criteria for usefulness and broader adoption
http://open.umn.edu/opentextbooks/ - the University of Minnesota's open textbook library list, including many MBX books
https://openstax.org - another publisher of a variety of open access books, sponsored by Rice University
