Howard Stearns works at High Fidelity, Inc., creating the metaverse. Mr. Stearns has a quarter century experience in systems engineering, applications consulting, and management of advanced software technologies. He was the technical lead of University of Wisconsin's Croquet project, an ambitious project convened by computing pioneer Alan Kay to transform collaboration through 3D graphics and real-time, persistent shared spaces. The CAD integration products Mr. Stearns created for expert system pioneer ICAD set the market standard through IPO and acquisition by Oracle. The embedded systems he wrote helped transform the industrial diamond market. In the early 2000s, Mr. Stearns was named Technology Strategist for Curl, the only startup founded by WWW pioneer Tim Berners-Lee. An expert on programming languages and operating systems, Mr. Stearns created the Eclipse commercial Common Lisp programming implementation. Mr. Stearns has two degrees from M.I.T., and has directed family businesses in early childhood education and publishing.

Touchability Cues

When I wrote “Touchability,” it had already been a while since a buddy had shown me a haptic mouse he was working on. For example, you could feel an actual bump when the mouse enters and leaves an object (a real version of what developers sometimes call rollover). Force feedback was such an obviously good thing that I didn’t even mention then the cool stuff that’s now happening in this area.

As much as I think physical touchability is good, I want to be clear that I want to make Croquet applications be emotionally touchable, too. I want to capture what it is that makes things seem (be?) real. Even without physical force feedback, it should still be fun to fondle stuff because of active visual and aural responses and good 3D design.

To be sure, I’d love to add to the effect with more sensory stimulus. There are huge possibilities, and I hope folks will explore them. This stuff is cool. There’s someone working on stereo display for Croquet. Others working on large screens in public spaces. I don’t doubt that we’ll see Croquet on small or cheap devices. There’s plenty of room for innovation.

Them's Fitin' Words, Craig

When I first heard about the $100 laptop project, I didn’t get it. Sure, I saw the value in having one laptop per child worldwide – I’m not stupid or mean – but I didn’t see why it wouldn’t just happen on its own. Prices are falling all the time. To make this project happen, it didn’t require a world-class engineering team, it required a team of world-class shoppers, I thought. My mother-in-law should run this project. I even argued with Alan Kay about it, to the point where folks had to come take him away before I was able to understand why so much effort needed to be poured into this right now.

I was wrong, and Alan was absolutely right. (Big surprise, no?) I have been convinced by these dismissive remarks by Intel Chairman Craig Barret.

Network Model Security

Last week I described the network model we’re building for Croquet, and was asked about some security issues. I think the main security weaknesses to what I have described come from the ability to misrepresent oneself as the Introducer or as a machine responsible for a World, or to deny others access to a World or the Introducer by sending a bunch of messages to it that demand its attention. Part of the answer in both cases is to distribute the roles of Introducer and of Worlds among many machines

ICANN Considered Boring

Last week was the World Summit on the Information Society in Tunisia (“the land of civilization, culture and enlightened thinking”, according to the official Web page). It has been reported that the conference was supposed to be about narrowing the digital divide. Croquet architect and all-around Computer God Alan Kay presented a model of the dynabook, er, $100 laptop to UN Secretary General Kofi Annan, while his buddy Nicholas Negroponte presented one to the Pope. Picture here. (And there was much amusement in the Stearns household when we realized that this made me one degree of separation from Annan and two from the Pope.) A lot of world leaders were taking this theme very seriously, but I hear the conference turned out to be all about US control over the ICANN system for Internet domain names. Even more leaders were taking seriously this idea, as argued by countries like China and Iran, that the world can’t accept ICANN to be under the control of a rogue state that practices state censorship, executions, unilateral invasion, torture, use of chemical weapons, etc. President Bush chose not to attend, in order to that he might visit Asia and criticize China regarding human rights.

The ICANN flap is interesting in several ways. There’s the timely main story in the news about the relationship between the US and the rest of the world. Then there’s the timeless backstory about the idea that progress is not achieved by consensus or committee, but by someone actually doing something that works. That’s what the US did. We only got into trouble because it was successful. I’m fascinated by this idea lately as it relates to development within Croquet. It’s hard for people who feel excluded to do other than to demand sharing, and particularly hard for them to realize that nobody “anointed” the folks who are producing the stuff they want to be shared. People do stuff and it works. Then other people want it. The trick, if it were possible to optimize such things, would be to share when things aren’t yet working so that others might join in the creative fun. But too many cooks and the management cost of such “optimization” can easily spoil the soup. It’s a dicey thing. I know, because I’m on both sides of the problem right now.

But the most noteworthy thing of all, to my mind, is that the ICANN flap is all so unecessary. US officials say the current system works just fine, technically, and they’re sort of right, except that the rest of the world says it doesn’t, and they’re right too. But I think there’s a much better way to handle the mapping of addresses, which we’re currently trying to build out in Croquet. Whether we’re the ones to do it or not, there’s no technical reason that the whole thing can’t be done in a way that makes the whole political argument moot.

Eroica

Today was my boss’s last day, and, ironically, my first anniversary. Julian Lombardi will be Duke’s Assistant Vice President for Academic Services and Technology Support. He’ll be responsible for the university’s IT customer service and development.

They made him an offer he couldn’t refuse.

Touchability

I’ve been trying to capture “what it is” about software that has a sense of fun, is toylike, and which allows users to feel they are directly manipulating “real” objects that they more-or-less understand. I want to shorten the link with pen pointers instead of mice. That’s a lot of words. There’s something more basic.

Touchability. I think human beings are uniquely wired to fondle stuff, and to want to do so. My dog sniffs and tastes. Ants use their antennae. We comprehend and alter the world with our hands. I play with my so-touchable wine glass, but not with the utilitarian water glass next to it. No child can resist touching a musical instrument left out, particularly strings and pianos because they don’t need lips. I always reach for my leather coat before my ski jacket. Bad Flash sites are visually stimulating, but good ones make me want to touch it all over to be rewarded with workings and sounds.
