Packt Publishing is currently running a "Skill Up" promotion with the tagline, "Learn More to Earn More." There are three separate special offers associated with the Skill Up promotion. One option is to purchase any e-book or video for $10 (USD). Another option is to select a "bundle" of five e-books for a total of $25 (USD) for that bundle ($5 per book). The third option is one year's access to PacktLib for $80 (USD).
The "bundle" offer (five e-books for $25 USD) appears to apply to any five e-books or videos in Packt Publishing's large catalog. However, there are several pre-selected bundles ("tech playlists") available for developers wishing to purchase these books in one category. For example, here are some of the available pre-selected bundles:
- "Skill Up | All You Need AngularJS"
- AngularJS by Example (March 2015)
- AngularJS Web Application Development Cookbook (December 2014)
- Mastering Web Application Development with AngularJS (August 2013)
- AngularJS Web Application Development Blueprints (August 2014)
- AngularJS UI Development (August 2014)
- "Skill Up | Comprehensive Android"
- "Skill Up | Functional and Reactive Programming"
- "Skill Up | Dedicated DevOps"
- Continuous Delivery and DevOps – A Quickstart Guide - Second Edition (December 2014)
- Mastering Python [Video] (30 April 2015)
- Mastering Git [Video] (31 December 2014)
- Mastering Puppet (July 2014)
- Jenkins Continuous Integration Cookbook - Second Edition (January 2015)
These are several more pre-selected bundles available than those shown above, but I created and purchased my own "tech playlist" with a PostgreSQL database theme:
- "Dustin's Skill Up | PostgreSQL"
The "list" prices for the above five PostgreSQL books would have totaled over $140. It was nice to pay only $25 for all five of them.
As part of the "Skill Up" promotion, reports on developers' salaries are available. The purpose of these appears to be for developers to determine the salary ranges associated with certain types of skills and then, in theory, a developer could purchase e-books and videos on those topics of interest (and associated with promising salaries) to learn those skills.
The "Skill Up" promotion appears to have just started, but I don't know when the "Skill Up" promotion ends.
