ABSTRACT
The Archimedes Palimpsest is a 10th Century medieval manuscript that is the subject of an ongoing technical, scientific and conservation effort at the Walters Art Museum in Baltimore, Maryland. Since 1999, the multidisciplinary team has been disbinding, conserving, imaging, analyzing, transcribing and studying the 174 parchment folios – yielding approximately 400Gb of data to date. The Palimpsest, which the team affectionately calls “Archie,” includes at least seven treatises by Archimedes: The only copies of two of his Treatises, /The Method/ and /Stomachion/; the only copy in Greek of /On Floating Bodies;/ and copies of the /Equilibrium of Planes/, /Spiral Lines/, /The Measurement of the Circle/, and /Sphere and Cylinder/. It also contains 10 pages of text by the 4th century B.C. Attic Greek orator Hyperides; six folios from a Neo-Platonic philosophical text that has yet to be identified, but may be commentaries on Aristotle; four folios from a liturgical book; and twelve pages from two different books, the text of which has yet to be deciphered.

ABSTRACT

Video is becoming increasingly important content type, and it’s time to make video a first-class citizen on the web. The element is, along with JavaScript bindings, proposed as a simple solution to encourage browsers to support video natively. Equally important is the choice of video format to be used with. I will argue that the success of the web is based on using open standards, and that video should be no exception. I will demo Opera showing Ogg Theora video clips natively.

A demonstration is available here:

Web Services Middleware: All Grown Up!

ABSTRACT
The term Web services carries the connotation of (slowly) doing RPC over SOAP. While many original SOAP toolkits supported and promoted that model (including Apache SOAP which I created), that is not at all what Web services are about. Apache’s history with Web services has seen three generations of efforts: Apache SOAP, Apache Axis and now Apache Axis2.

Axis2 is fundamentally different: instead of treating XML as a hot potato that must be replaced with a language structure immediately, it treats XML lovingly and offers a very clean processing model for XML. Of course it does support data binding for those that want to look a the XML as objects but the core of Axis2 is a pure XML processing architecture.

Axis2 is the basis of a new kind of enterprise middleware. Building on that core stack we have built support for the entire security protocol (Apache Rampart and Rahas) set as well as for reliability (Apache Sandesha) and transactions (Apache Kandula). Apache Synapse is providing ESB like message and service mediation capabilities on top of Axis2.

Axis2 supports both WS-* style services as well as XML-over-HTTP (POX) style services. We’re also working on JSON support and a host of other cool stuff. We support HTTP, SMTP and JMS with other transports on the way (including XMPP).

The Axis2 architecture is being implemented in both Java and C, with the C version bound to PHP and other scripting languages as well as Firefox, IE and other hosts.

In this talk we will introduce the new generation of Apache Web services middleware. Read the rest of this entry »
