For Open magazine subscribers 

As part of the e-commerce push, the E-SIGN Act makes it possible for
companies to contract, buy and sell on the web. But to do so requires
trusted e-signatures. Enter Yozons, whose web service lets business
customers confidently send, receive, and authenticate documents. This
week, Yozons' chief software architect talks about building e-commerce
architectures with federated Open Source solutions using Apache and
PostgreSQL.

On the database front, we ask you: What do you know about Open Source
SAP DB? If you say not much, SAP's own database experts won't be
surprised, just very, very eager to turn up the volume. This week, we
talk to Dr. Rudolf Munz, one of the SAP Open DB seers now plotting
guerilla tactics against the RDBMS ruling class.
