Dear Diary,

I’m off to Japan Tuesday for the big conference. Better take a snapshot of what I’ve been doing, because I expect my world to change by the time I get back. My first six weeks on this radical Croquet project were spent with very general learning of what’s what. Drinking knowledge from a firehose. For the next six we’ve been prototyping some of the features from conference papers written by my boss, Julian, and his counterpart at U. Minnesota. We’re going to demo these at the conference, and we go on right after Alan Kay’s keynote address. Yikes. Good thing Julian gives great demos! I imagine the conference organizers know that and put him in that slot accordingly. (Cast of characters here).

So, you join a university team that is in the middle of a project that is throwing away the models of how computer programs and interfaces work and starting again from scratch. Where do you begin?

There's a nice outside review of the scope and implications of the Croquet project in
this person's blog.

This is deep stuff — too deep for me to fully grasp in my first two months. So I started by sorting out the people and their projects. [Read More!]

Croquet is still being designed. Personally, I’d like to see something useable this summer, but that remains to be seen.

There is a “developer's version” available now, called Jasmine, but there's some confusion as to what Jasmine is in relation to the real thing. I’m going to try to straighten that out here. [Read More!]

In this information-laden world, who really wants to deal with addresses, ss#'s, a bevy of phone numbers, even more account numbers, part numbers, and on and on? It seems we sometimes need the precision afforded by (usually non-mnemonic!!!) names, but we don't like it. What if it's not necessary?

My boss has blog on blogger, which I gather is now owned by Google. Hard to believe that the “Don't be evil” folks have a hand in this monstrosity. [Read More!]

Here's a glimpse of the future. Can't wait 'till Croquet is ready to play.

There's a new PlayStation 2 game called Karaoke Revolution. You sing into the computer while an animated character lip-syncs. The game grades you on your pitch and timing, and the animated crowd goes wild or boos you off stage as appropriate. [Read More!]

Croquet is “about” real-time collaboration. A bunch of people can be in the same virtual environment and see the live effects of each other moving around and manipulating things. It seems natural to add audio chat using existing Voice Over Internet Protocol (VoIP) technology. So now you can talk to folks in the same space while you work together. We're working on Webcam video, too, so that it's generally suitable for holding distance meetings in a Croquet place. I didn't think much about displacing land-line telephones. Who cares.

We thought a bit about how you could connect the telephone system so that you could call in to a Croquet place and join a meeting (audio only?) from a cell phone.

But then I read this quote from Patrick Scaglia, Vice-President and Director of the Internet and Computing Platforms Research Center at HP Lab:

“Croquet is a first in many ways. It represents a major step in our vision of computation as a communications platform and service, available anytime, anywhere, from any device. Soon, Croquet will run on everything, from a PDA through a set-top box; persistent Croquet worlds will be ubiquitous on the Internet, routed intelligently to each user through computational services overlays like PlanetLab. This will change the way people think about software and computation, from today’s device-oriented perspective to a perspective of computation as a persistent, pervasive, service”.

It took a day to sink in.

Eventually, people will want and get always-on connectivity for mobile devices, just as over half of American Internet users now get for fixed-position access. After demand evens out, I think device costs are first-order proportional to the number of chips, with the complexity of chips being a second-order effect. So the cost of a PDA capable of running Croquet will someday not be inherently much more expensive then a cell phone such as is now being given away by providers.

So, will we have telephones? Of any kind?

As far as I know, the Croquet developers didn't set out to replace the telephone. If I had, my wife would have threatened divorce for such a hair-brained idea. And I'm not predicting that Croquet will displace the telephone. But it is interesting that progress in solving an abstract and general problem
mightlead to the merging of computers and telephones.

The real-time collaboration in Croquet is cool. It provides a very different way of structuring applications that will allow things that nothing else can. The croquet team is working hard on this aspect. But we're just begining to consider the implications of shared persistence. I think this is just as radical in itself, and will inspire truly extroadinary software when combined with Croquet's other aspects. [Read More!]

Croquet is an ambitious project to develop an entirely new way to work with computers, including 3D user interfaces and real-time collaboration between separate people manipulating the same virtual objects. Although this could be used in many domains, the focus of the core developers is on educational uses.

Imagine you could make computers work however you wanted. What would you have them do? That’s what we’re trying to figure out. Fast machines. Graphics coprocessors. Fast worldwide networks. And it’s only going to get better.
