Would you like to upgrade your ereader, or give an ebook reader to a friend? This post you’ll find suggestions and advice on ebook format, digital rights management, and improved night reading.

Book Format

If you aren’t sure about the recipient’s favorite way to read ebooks, give them an ereader that will read ePub books. This standard format is supported on every platform by dozens of e-reading applications. A book published in the ePub standard format will be available no matter what happens in the marketplace, or whether they shift to a different reading platform in the future. Furthermore, there are numerous easy ways to convert an ePub book to be read on Kindle readers.

A book based on the proprietary Kindle format can be converted to other formats, but the process isn’t easy and the results are less than ideal. However, if you know absolutely that the user has and prefers an Amazon Kindle, then you can gift them either format. They have already accepted the technology risk associated with the Kindle format.

Digital Rights Management (DRM)

If a book is protected by Digital Rights Management (DRM) it may be difficult to read on other platforms. If possible, purchase a book without DRM protection.

If the publisher of the book insists on DRM protection, your choice of platform could become important. Apple and Amazon books with DRM cannot be read on any third-party device or application.

In contrast, Barnes & Noble, Kobo, and many other stores sell book with the standardized Adobe ADEPT DRM technology that third-party ereaders can properly decode and display on any platform.

LED versus e-ink

For the choice of reading device, the only significant criteria I have found is the choice of LED screens versus e-ink screens. Some people have a difficult time reading LED screens for a long period. Other people (myself included) can comfortably read LED screens for any length of time. If you want to gift someone with a new or upgraded reading device, try to learn how they feel about reading on LED screens.

The following readers provide front-lit displays that don’t shine light directly into your eyes:

  • $99 on sale: The Nook Glowlight Plus is a dedicated e-reading device. This device can display any book in ePub format, ensuring upgrade protection and allowing purchase from many book vendors.
  • $99 on sale: Kindle Paperwhite can only display Kindle-format books.
  • $119: Kobo Glow HD is a dedicated reading device which uses Kobo’s reading software.
  • €119: inkBook Obsidian is a full featured Android e-ink device which can utilize any Android reading app, including Kindle and Nook apps.

There is a wide variety of devices with LED screens, so you can pick any one which meets your needs. I recommend that you acquire and use blue light filters at night to prevent the well-documented effects of reduced serotonin generation.

My favorite writing tool is Scrivener. I wrote the Learning MCollective book for O’Reilly Media entirely in Scrivener. I was afraid this wouldn’t work very well, but it ended up working just great.

To do this, I created a Scrivener compile format which set up chapter headings correctly with a link target above them as recommended. Then I wrote some scripts to process the output from Scrivener compile to make AsciiDoc in the flavor that O’Reilly wanted.

I have released my Scrivener compile settings and scripts so that others can use them should they want to produce asciidoc from Scrivener. They are open source under an Apache license at https://github.com/jorhett/scrivener-asciidoc.

As previously reported in my ActiveMQ 5.9.1 RPM post, I’ve created an RPM for Active 5.9.1 on RHEL/CentOS that matches the one published on the Puppet Labs EL6 dependencies repository.

I discovered last night that I hadn’t included the new REST apis in the image. So there is now a new version. I’ve bumped the release version so that you can upgrade if you installed the previous version.

Learning MCollective is now available in Early Release.

This has pretty much every chapter and subchapter we expect to have in the final book, but my editor and I are still polishing some rough edges. As O’Reilly says on their website:

You’ll receive updates when content is added, as well as the completed ebooks. You get free lifetime access, multiple file formats, and free updates.
