Free Books and Articles For Subscribers Only

To open these PDF documents, use the password provided when signing-up or in any edition of our newsletter. The summary is accessible to everyone. When clicking on a “download” link, you get two options: view or download the file. The download option is much faster: the view option takes time to render all the fonts and pictures on the screen (up to 30 seconds for large documents). If you already have a copy of some of these documents, check out the version. The most recent version is posted here.

The LaTeX source is available to subscribers only, and contains the images, bibliography and the source code (in a zip file) used to produce the document. It allows you to easily copy and paste the Python code, change the style and formatting (such as font size) to your liking, or for easy inclusion in other documents. To access it, click on “Full version”. All the Python code is also on GitHub.
