I did another Whitebook (in dutch). This time the subject is New Features in the APEX 4.0 Early Adopters release.
You can find it at the Whitehorses website.
By the way; besides this personal blog I also publish articles on the blog at the Whitehorses site together with the other Oracle, Java and SOA specialists of the company. These blogs are in english. A direct link to the list of my blogs is in my profile.
Last week my latest Whitebook article was published at the Whitehorses company website.
The article is on the RFID implementation at Centraal Boekhuis. That is the biggest partner in logistics for books in the Netherlands and Benelux region. There I worked on the first big RFID implementation for a retail supply-chain in the Netherlands.
