Various components in this repository were obtained from other sources, all of which have compatible licenses, and all of which are listed below. Anything not listed below is released under the CC BY-SA license mentioned above.

• reveal.js (used for the slides), released under an MIT license
• Some of the images
  • The green double arrow (slides/images/green-double-arrow.png) was adapted from openclipart.org, specifically here; the red double arrow (slides/images/red-double-arrow.png) was adapted from that as well. These images are released into the public domain with no restrictions; see here for details.
  • slides/images/menu-icon.png is from here
  • slides/images/print-icon.png is from here; the license requires a linkback, which was that link.
• Some of the code in canvas.js was adapted from two Stack Overflow posts: here and here (which code was adapated from those posts is described in the canvas.js file).
• The DHTML Window Widget (in dhtmlwindow.js and dhtmlwindow.css file) was taken from Dynamic Drive, along with the various images (close.gif, max.gif, min.gif, resize.gif, and restore.gif); the full license is in the dhtmlwindow.js file.
• The UNIX tutorials are from here, and is released under a CC BY-NC-SA 2.0 license.
• The How can I serve an evil genius flowchart and prediction flowchart for geek gifts were both from here. The license description is here, which states that it may be used for “non-commercial” purposes.
• While the xkcd images in the daily announcements are not included in this repository, the xkcd heap/tree image, from xkcd #835 is included so that this slide set can be viewed off-line. The license for the xkcd material is a CC BY-NC license, which means it’s compatible to include it in this repository.
• The airline route image in the Graphs slide set is from Openflights (it’s this image on the bottom of this page), and their FAQ states that their license allows for non-commercial use.
