Apress is offering free ebooks online. This is not a limited time offer. You can find out more about it on their site.

Preliminarily, here are some of the offerings that I found:

  • TouchDevelop 3rd Edition
  • Managing Risk and Information Security
  • Intel® Xeon Phi™ Coprocessor Architecture and Tools
  • Intel® Trusted Execution Technology for Server Platforms
  • Building the Infrastructure for Cloud Security

I downloaded two that were not listed on their ApressOpen home page:

Thank you, Apress.
