No Deal, Charles

I agree that we are on the precipice of a disaster. I would like us to act to prevent it. I do not insist on assigning blame or even being fair in how we act, as there will be time for that later. The only thing that is required of how we act is that it solves the problem.

No one has explained to me how taking the bad loans off the books of banks actually solves the problem. What has been explained to me by the officials and the politicians is that there is far more money at risk than that tied up in these loans. The money has been promised to average Joes, governments, and wild speculators, based on the idea that other average Joes, governments, and wild speculators will pay even more for these incomprehensible instruments in the future. At the original bottom of this pyramid are the at-risk loans. Yes, I agree that there is a crisis of confidence in the market, as the President put it. But I fail to see how now the politicians now suddenly understand these instruments, and that the way to keep them from collapsing is to take the loans off the books of the banks.

Are they saying that they intend for average Joes, governments, and wild speculators to keep shoveling ever-increasing amounts of money into the derivative market based on these loans? Ponzi schemes do collapse when triggered by a failure of confidence, but a child can see that even with no failure of confidence, they can only be sustained as long as there are increasing amounts of investment at the bottom. Eventually, the world runs out of money.

Now is the time to drop a note or leave a message for your representatives and let them know how you feel. Their contact info is online. Don’t forget to tell them that you’re in their district/state.

The Other Road Ahead

, , , ,

Last time I argued that from a technical perspective, the “server”, “client”, and “P2P” labels were complicated. That narrow view deliberately ignored the roles that these technologies have on the user, and on communities and business built around them.

I’ve been looking back at Paul Graham’s 2001 essay on “The Other Road Ahead.” He laid out a bunch of benefits that accrued from his successful company’s use of what he called a server-based architecture. While Viaweb originally relied on generic “Web 1.0” clients not distributed by his company, his essay looked ahead to richer clients such as what would come to be known as “Web 2.0.” I think the essay applies just as well today to mixed-technology deployments like Google’s current development. And I think it applies to some Croquet deployments, including those by my employer Qwaq. A lot of what Paul describes turns out to be things we’re already doing. But by explicitly identifying the benefits and what enables them to be realized, even a peer/client-centric geek like me can appreciate the operational value of the different technologies I’d mentioned last time. From this perspective, I’d say we’re “half-server-based.”

Worth a read (as are his other essays). See if you don’t agree.

What's a Server?

, , , , , ,

I was taught that science is all about managing complexity by creating abstractions over different domains. A common layman’s mistake is to anecdotally observe or hear that something is true at some level, somewhere, and assume that this fact or definition applies throughout every discussion. For example:
One hears that computers are “programmed in binary,” or that they “understand binary,” but in fact, programmers don’t write in binary. Programmers work at a higher level of abstraction than binary encoding.
One hears that computers use “digital circuits,” that are simply “on” or “off”, but in fact, the physics of each electronic component is continuously variable. Device physics is at a lower level of abstraction than digital electronics.

So, what’s a server and what is peer-to-peer? It depends on what ‘s being discussed?

Computer-Generated News

,

<%image(20080830-abc-news.jpg|427|316|ABC News Story)%>

I’m old enough to vaguely remember Walter Cronkite forty years ago showing us hand painted “NASA Simulation” video of the Apollo spacecraft maneuvering in space. There simply was no way to position a news camera outside the Lunar and Command Modules to get the shot.

Now we have computer generated movies and commercials. I’ve seen computer simulations of plane crashes and of presidential candidates. But yesterday morning was the first time I’d seen computer-generated pictures of human participants in breaking news. I’m not sure I approve of the concept altogether, but given it’s existence I do like the editorial decision to render the named humans in untextured solid red.

Boring

,

We had had our usual weekly Engineering Meeting yesterday. Some slides, a couple of charts, some spreadsheet pages, and a bunch of folks arguing. Nothing exciting, although it was pretty cool for random attendees to change the slides and spreadsheet in real time, and to put post-its on them.

As usual, our weekly meeting was in-world. No one commented about the technology. No one commented about the fact that the meeting was lead by a manager away at MIT, some engineers were in Maryland and Oregon, and some folks were at home saving gas rather than in the office. Boring.

Pretty cool, no?

Going to California With…

, , , , ,

I like to think I’m particularly adaptable on those occasions when I happen to recognize that I need to be, but I perpetually feel inadequate in recognizing when the rules of the universe have changed. That’s a pretty significant skill to be lacking when you’re trying to invent the future.

So it is with even more than the usual range of emotions that I have come to “sell” our home in Wisconsin and will finally be moving to California. I am told that this is an extraordinary accomplishment, but I’ve “adapted” so much, the celebration has a Pyrrhic cast.

The US housing market has all but ceased to exist as a functioning market with any sort of liquidity. In my neighborhood, there should statistically be about one home sale each week. Ours was the seventh in the previous eight months, and I think all of those were the previous calendar year. The issue seems to be that every sale is contingent on having the buyers sell their home, which isn’t happening, so the whole country is waiting for one big circle jerk. Many housing industry folks are claiming that prices have not fallen much, but that’s disingenuous – the average selling price nationally and in most areas hasn’t fallen much only because the average home size continues to rise. The average price per square foot of any particular existing fixed-size house is dropping like a stone in a still pond. (Areas that do not see average housing sizes grow have indeed been seeing a big drop in average selling price.) And with bankers knowing this and knowing that several hundred of their ilk are being carted off by the FBI – no I’m not making this up – they’re not making a lot of bridge loans that would allow folks to buy one house before they sell the next.

So here’s what we did:

I predict a mini-rapture

, , , ,

For $40/year, this service will send an email to your loved ones after believers disappear in the coming rapture. There’s a deadman switch that will send the messages automatically if three of the five owners don’t log in every three days.

I guess I’m a believer, because I’ll bet those guys are going to disappear mysteriously. The site doesn’t say what happens to the money.

It might be kind of interesting to do this properly: let the designees of each individual account be notified if the account-holder doesn’t log in. Might be useful for journalists, abused wives, bloggers, and other folks in fear for their lives from governments and wackos.

Da5id's Vision

, ,

In January, 2005, David Smith was on stage at Kyoto University, speaking in a panel on the future of Croquet. Slouched in his chair, he pulled an iPod from his pocket and threw it on the table, along with his old-fashioned styled spectacles. “In twenty years, that will be the computer. Maybe earlier. Wearable computers and micro-projection display already exist. Virtual Croquet worlds will be layered onto the physical world around us.”

At the same time, in San Diego, CA, author Vernor Vinge was wrapping up “Rainbows End,” a novel set in 2025 in which the common person’s view of the world is augmented by wearable computers overlaying virtual worlds onto contact lenses. The central denizen of the worlds in the story is a troublesome white rabbit, which also happens to be a common avatar in the Alice In Wonderland themed Croquet worlds.
