It’s interesting how often 3D computer graphics comes up in my work-life. I guess it’s mainly a function of being vaguely good at it. In any case, it’s quite a bit of fun sometimes. A project I’m working on for a client now integrates 3D graphics and physics to do a vehicle simulation. It’s really getting me in the mood to make some sorta video game. I can think of this simulation as my first little 3D game, I guess, and see where that leads.

By the way, hurray for open source again. Irrlicht and ODE are both doing a very nice job, though I have to admit that there are some steep learning curves on some bits for both, since there are holes in the documentation (and the code). Still, glad I didn’t have to start this project writing code to pump tris and solve 20-some dimensional linear equations efficiently. I’ll get back to writing my own engines some other day :-).

I don’t have all my thoughts well-formed on this yet, but I should post something lest I have a genuine lull here…

I’m just going to put this is basic scenario-outline form. Please leave comments to fill in some details so that we can all think about this more. (Hehe, he thinks he has readers).

Say I want to build a weather website.

As a technologist, I ask: what kind of database will I use? Where will I host the site? What features will I assume in the users’ browsers? How can I reuse existing infrastructure and code?

As an HCI practicioner, I ask: what sort of tasks will the user be performing? What’s the best way to scope the information presented to the user? How should the site be customizable? How can I make this more useful to more users?

As a business developer, I ask: what is the value of this site? How can I get people to use it? Where will I get the data and labor necessary to maintain it? How can I integrate this service with others?

One can think about business as the art and science of incorporating human values as explicit variables into system design. A proper understanding of this, then, can lead to more robust, useful and long-lived systems, building on the previous layers of HCI and raw technology.

This is quite impressive, at least to me. Who’da thought that they’d keep coming up with uses for that there quantum mechanics knowledge? 🙂
EETimes.com – Micron-sized refrigeration device has no moving parts
I think the thing that was most impressive is the idea of using it for cryogenic cooling in sensor applications. Some day your blender and your cell phone will have a little 100mK chamber in it, and you won’t even realize how fantastically cool that is.

A friend of mine once related a story about a programming class he took in college. There was another student in the class who asked the professor on the first day: “This is all fine, but, how do we know what computers can do?”. The professor tried to give him an answer. But clearly the answer wasn’t good enough, because he asked the question each day for a few days, then dropped out of the class.

While one could have a little snicker about that story (I know I did :-)), it’s not that there was anything at all wrong with the question, it was just in an unexpected context. Had it been a philosophy-of-technology class, that would be the perfect way to lead off the semester.

Which leads me to my main point: that sort of simple question is worth pondering for oneself: “How do I know what I can do?”, or in a social context, “How do we know what we can do?”.

It’s not an easy question to answer, at least for me, but an important one, even if it’s only asked implicitly. I’m not likely to embark upon something unless, in some sense, I think it’s within the realm of possibility for me to do it. But how do I know what I can do? Having a clear understanding of where my confidence (and lack thereof) comes from would allow me to systematically probe the borders in different directions, rather than just waiting to accidentally get there by magic.

It occurs to me as I write that that the concept of confidence, and some ideas related to it, can be hollow if it is understood as some sort of a tank in a person that must be filled, but without knowing of what it is filled or how.

(Umm, this came out less well-formed than I thought it would, mainly because I’m learning about the topic as I write about it. Hope it was useful to you to read it…)

I take it back: it is possible to turn off almost everything but the focus-follows-mouse behavior in the True X Gizmo (that I mentioned earlier). Here’s a .reg that sets things the way I like ’em.

For the lighter side of and more serious discussion of how to do consulting badly, may I suggest:
Huhcorp: We do stuff. and Compass Newsletter (see the “Naked Consulting” series).

The sort of stuff touched on on these two sites is a reason to avoid calling oneself a consultant. But I don’t have any better word yet for what I do and wanna do. I suppose, though, that if someone’s view of me is materially informed by a single word, then I’m already headed down the wrong path with that that person.

Some stuff I’ve started listening to: U B U W E B :: Marshall McLuhan. Always good to hear from ol’ Marshall. I had not previously been exposed to his sound-collage facet. Cool.

Speaking of innovation and hence entrepreneurship, Lifestyle Entrepreneurs is a series of pretty interesting columns about people who have intertwined their entrepreneurship with their lives in general to get something that’s ‘not just a living’ (the title, by the way, of a book by Mark Henricks, the author of those articles (loc, amaz)).

That’s my goal with my consulting career, although there are times when that seems less possible than pithy titles would suggest. It’s nice, then, to see books and articles like these as a reminder that people can do this and also some details about how. I think there are still a few books to be written about this topic, because I haven’t been completely satisfied with any that I’ve seen yet.

I saw Jeff Lindsay giving a presentation called “The Magic of Patents” at ISU. Pretty entertaining to mix in some magic tricks, woven in in a way that actually made some sense to the presentation.

I’m still not sure how much magic there is in patents, though. The deepest feeling I had coming away from the talk was that patents were going to keep me from doing great things for the world. That feeling wasn’t permanent or well-reasoned, but it was still there. The fact that it’s so expensive and time-consuming to get a patent means that it would be hard for me to get one, yet (relatively) easy for some big company to come up after the fact, get a patent on something I’ve used successfully, then use the patent against me. I guess I just have to make sure to get some prior-art evidence documented for anything I think _might_ be patentable, then worry about all that stuff if it ever gets to that level.

But, like I said, the fear was not long-lived or necessarily reasonable. That’s the way I start to feel sometimes, though, when I hear legalistic stuff in its various forms. The sharp edges give my brain papercuts.

Patents are pretty interesting, though. That they’re (ostensibly) built around the idea of forcing inventors to divulge their work for the common good in order to get the incentive of enforced exclusivity for a period is a pretty neat idea in itself. Lindsay gives that idea credit for forming the core of the power of American innovation, and it’s hard to argue against that.

However, there’s still a big part of me that feels that there’s something not quite right about the way patents work. At this point, though, I can’t clearly articulate that, so I’ll just take comfort that it all seems to work pretty well pretty often as a component of an economic engine and a social structure that I can’t pretend to understand well enough to solidly critique :-).

I’m thankful for… communication networks. I wonder how different my life would be if I didn’t have ready access to such a vast variety of people and their works through a few simple portals like computers and phones.
