Packt Publishing is having their end of year sale, all of their ebooks and apparently their video courses are $5! I just purchased a CCNA course for $20, which was three ebooks and a complete video course, normal cost would be around $260! I formerly was CCNA certified and have been thinking about doing a refresher and maybe reacquiring that cert. I know they expanded the knowledge required to include firewall configuration, so it should be interesting, plus now everything is GUI-based for router/firewall configuration compared to all of the command-line stuff that I had to know. Plus my knowledge of IPv6 is really dated as back when I was certified it was REALLY early v6, I have no idea how they're doing routing of it these days. Should be interesting.
Sale should be running until about the end of the year if past trends are any indication. Their books are typically in PDF, Epub, or Kindle format, all DRM-free. Some time in January they'll go back to having one book a day available for free: I've acquired approx 500 ebooks and many zip files of code samples this way over the years. Many topics that I have no personal interest in currently, but you never know when interests might change and you need to bone up on something.
