Topic:    The Lively Kernel
          A Self Supporting System on a Web Page

Speaker:  Daniel Ingalls
          Sun Laboratories, Menlo Park

About the talk:

The Sun Labs Lively Kernel is a new approach to web programming.
It provides a complete platform for web applications, including
dynamic graphics, network access, and development tools, and
requires nothing more than available web browsers. We call the
system lively for three reasons:

It comes live off a web page. There is no installation. The
entire system is written in JavaScript, and it becomes active as
soon as the page is loaded by a browser.

It can change itself and create new content. The Lively Kernel
includes a basic graphics editor that allows it to alter and
create new graphical content, and also a simple IDE that allows
it to alter and create new applications. It comes with a basic
library of graphical and computational components, and these, as
well as the kernel, can be altered and extended on the fly.

It can save new artifacts, even clone itself, onto new web pages.
The kernel includes WebDav support for browsing and extending
remote file systems, and thus has the ability to save its objects
and "worlds" (applications) as new active web pages.

The Lively Kernel uses only existing web standards. The
implementation and user language is JavaScript, known by millions
and supported in every browser. The graphics APIs are built upon
SVG (Scalable Vector Graphics), also available in major browsers.
The network protocols used are asynchronous HTTP and WebDav.

The Lively Kernel is being made available as Open Source software
under a GPL license. While it is not ready for use as a product,
we expect significant participation from adventurous developers
and academia.

About the speaker:

Dan Ingalls is the principal architect of five generations of
Smalltalk environments, culminating in the release of Squeak, an
open-source Smalltalk system written in itself. He designed the
byte-coded virtual machine that made Smalltalk practical in 1976.
He invented BitBlt, the general-purpose graphical operation that
underlies most bitmap graphics systems today, and also pop-up
menus. He has received the ACM Grace Hopper Award for Outstanding
Young Scientist, and the ACM Software Systems Award.

Dan is currently at Sun Microsystems where he is working on the
Lively Kernel, a self-supporting computing kernel that lives on a
web page and requires no installation.

Dan Received his B.A. in Physics from Harvard University, and his
M.S. in Electrical Engineering from Stanford University.
