My current passions are object-oriented programming, Java,
the open-source movement, data mining, spatial interfaces,
and adaptive software,
as exemplified by the Java open-source
A related project,
is intended to give
infrastructure support for remote peer-to-peer Java development.
Symphony will carry a new class of user interfaces,
built with yet another project,
2005, design document)
an editable, exportable, and sharable user interface builder intended
partly for non-programmers (also called `end-users')
as well as programmers.
These are all application projects of my ongoing
design patterns seminar,
Alpha versions are here:
KnownSpace is a visual and adaptive personal data manager.
Why do I feel it's necessary?
Here is a
fable on web data management,
an explanation of
what's wrong with today's interfaces,
a Star Trek example of
how context can improve search,
a comment about
why personal computers don't exist yet,
a discussion of
why software designers make us monkeys at the keyboard,
a sketch of
how much more personal computers could easily become,
and a story explaining
why today's computers suck.
KnownSpace is related to several other projects
in interfaces, adaptive software,
intelligent agents, collaborative filtering, networking, searching,
TimeScape (pdf file),
the open-source projects:
and the commercial efforts:
and now (Spring 2008)

Here's an overview paper,
A New Data Model: Persistent Attribute-Centric Objects,
with Ricardo Baeza-Yates and Terry Jones.
I also write books.
