I've recently had the privilege to work with DZone.com and write an article for their Refcardz series about HTML5 Web Workers.
The article combines the information presented in several of my blog posts and also introduces some new information and concepts like transferable objects, inline workers, as well as a link to a sample project.
The DZone.com article can be found here: https://dzone.com/refcardz/html5-web-workers
