David Brin, whom I debated on the topic of Transparency yesterday, has been putting forward for some time the general idea of a henchman's amnesty law. Namely that, in the event of a criminal conspiracy, the first underling who whistle-blows can get some level of amnesty, witness protection and/or cash reward. A serious reward, in the millions. Such a rule would make it harder to pick henchmen, since in effect you're making them a millionaire if they turn on you.

We see the talk of an America divided in 2, but in fact it's not. There are more viewpoints than that. Normally a 2 party system tends towards the middle, this election was unusual in having a larger than normal difference among the candidates.

But perhaps now is the time to take the Democratic energy and try to push it into a movement for real reform. Not ballot recounts, not crazy dreams that can never happen.

Idea futures are interesting, so I went to tradesports.com to buy Kerry Futures contracts, since I believe pre-election polling is notoriously poor in quality. They were trading at 43 for a contract that pays 100 if he wins, and that seemed a good buy. By the time I could buy them (slow site, overloaded) they were 50 but now they are at 71. The bidders clearly have developed a strong reversal of feeling.

Today the word went around about mypollingplace.com, a site that helps people find their local polling station, running out of bandwidth from their provider and needing somebody to help it.

At the same time I did an interview for opinions about bitTorrent, and the idea came to me that a really useful application would be a P2P generalized web hosting tool aimed at spikes.

Volunteers who have a reachable IP address (including people who can open holes in NATs) would install software to volunteer to help host sites in need during a spike. This could be client software in a browser or permanent server software.

Then a few different things could happen. Ideally a site would install a tool which activated the sharing network when their load got high (but well before their provider cut them off.) People fetching static pages that weren't sharing bandwidth would be redirected to a port willing to share. The page would also be modified to encourage folks to join the process. Folks who were willing to share might get access or be redirected, and they would cache the page, declare where it resides and serve it there for some period of time or number of hits.

If a site didn't install the fancy redirector, they could redirect all web hits to a volunteer tracker that would do a further redirect to a real location willing to host the item.

Finally, for sites totally unaware of this, a browser plug-in could notice when access to a page is very slow or gets a "bandwidth limit exceeded" message. It could then query to see if any of the P2P folks have cached the page, and fetch from there, or offer the user a button to check or fetch from that network.

This latter mode is good because it strongly encourages having the magic plug-in with your browser. If you don't have it, you can't get at the P2P cache.

I've been informed that Coral from NYU does some of this, though it doesn't do the "on demand" aspect that leaves the web in normal state when not overloaded, and switches to cacheing only when needed. With Coral and other redirects, your Google adsense doesn't show up either!

There has been much writing (including here) about problems with the Electoral College in the USA, and I've even proposed solutions such as a tiebreaking system for close votes. I also noted the amazing coincidence that in the 4 times the winner of the college lost the popular vote, 3 were the 3 times we had a son or granson of a President elected.

But I thought it might be worth exploring the merits of the college, even though most individuals want it abolished. (Though no smaller states want it abolished since it gives them disproportionate power.)

Tonight, I saw for the first time (for me) a drive-by trick-or-treating. I'm not talking about the growing phenomenon where parents drive their kids to wealthier neighbourhoods for a better class of candy. We had put out a ghost made from gauzy material with a very bright cold-cathode light inside, and hung it over the street. As I stood on the street a minivan pulled up and quickly stopped. Two children went to our front door and Kathryn gave them candy. Then we watch them get back into the van and it continued down the street, out of sight. The appeared to be cruising and stopping at houses with decorations they noticed, which can be found in many neighbourhoods.

You may have heard of the vote-trading concept, where a voter in a "decided" state (whose vote will make no difference) who wishes to vote for a major candidate pairs up with a voter in a swing state who wants to vote for a minor candidate. The idea is they swap choices. The swing state minor party supporter votes for the major party candidate (typically Kerry this time) and has a chance at making a difference in the swing state.

We've seen the explosion in Voice over IP phone companies, using lower IP costs (and regulatory bypass) to offer very cheap long distance. Today, in the wholesale market, you can place VoIP calls to regular phone numbers in the major cities of the world for between 0.5 cents and 1 cent per minute. So cheap that companies are routinely offering people "unlimited" long distance plans for a flat monthly fee.

The rates are cheap, but they aren't yet free, so calls don't happen without contracts and plans and arrangements.

Here's something begging to be done: The cellular carriers in the USA and Canada should allow people calling in from the internet to call any cell phone for free.

This would cost them the tiny amount they get for terminating long distance calls to cell phones, but the end result would be their own customers billing more minutes. That's what they want (sort of.) They could release a free program for use on common PCs to call any cell phone. They could have a java applet or ActiveX control to make a web page to let you call any cell phone for free, just as they let you send an SMS from a web page for free. (If you have a headset with a mic, at least.)

But allowing free and open calling would encourage lots of innovating applications from the marketplaces. Smart PBXs would coordinate and connect with company cell phones over the internet. More advanced apps would link cell phones closer to PBX functions. People who use their cell as their home phone would have another reason to do it -- now all their friends can call free from VoIP phones or any PC. Companies like Vonage would offer free calls to cell phones even for people not on the unlimited plan.

Soon as it was out, I bought the EOS D20. I sold my D60, which I had replaced my D30 with, so I am obviously generally pleased with Canon's line. The new camera has a lot over the D60 -- 2 more megapixels (or 3500 high for panoramas), much better low-light shooting ability with low-noise high-ISO, and fast shooting (5 frames/second for 25 frames.) It also has better focus, better controls, and an orientation sensor, something I've been wanting for a long time.

Many people like the idea of soda fountains, but the official fountains that mix soda and pre-mix concentrate are quite expensive and work to maintain.

To gain some of the convenience and efficiency, how about a quasi-real fountain using existing 2-liter pop bottles? Such a fountain would be designed to look like a regular one. Inside, ordinary 2-liter bottles would be attached. In a "party" model, they would just be in an icebox, in a full-time model it would have refrigeration.

I've written about a few plans to get rid of the headache (and travel killer) that airport security has become. One of the great curses is that because you can't predict how long security might take, most people end up arriving way, way ahead of their flight in case the line is long, but often they clear it in just a few minutes. (Ditto the immigration/customs line at Canadian airports going to the USA.)

I have often heard it said that being a Senator is a good stepping stone to President of the USA. Research shows this to be really false, and that's bad news for Kerry. Oh, many sitting senators run for President, but for over 120 years, they have rarely and barely won.

Well, a couple of weeks ago when I announced the phone project at Burning Man, I implicitly was linking to my new galleries for Burning Man 2004. However, let me officially announce those galleries now, plus the addition of a new gallery today.

An out of left-field idea. It doesn't happen a lot, but one of the things people fear deeply is being bitten by a shark. Sharks sometimes bite surfers, because, it is suspected that 4 paddling arms lying on a surfboard triggers the "tasty seal" match in the shark's brain.

(Reportedly sharks don't actually like how we taste that much, and have spit out human limbs they bit off. I dunno, but somehow that's adding insult to major injury.)

Ok, it's not like we're crying for a new word, since we already have so many: Generation Y, Generation Next, Boomlets, Echo-boomers, Millenials etc. But still, I like to throw out new words so mine is "Boomerangs" which nicely captures the concept of the rebound of the Baby Boom, and a few other concepts as well.

I'll be speaking at three conferences in the near future, and can offer discounts to blog readers for two of them.
VoIP
Coming up October 19, I will be speaking on the future of SIP, and whether IAX2 or Skype might kill it, at the Pulver Voice on the Net conference in Boston.
Nanotech and Privacy

Tested my UPS systems and found them wanting in Friday's 10 hour Cupertino blackout. Last week I wrote about my longtime desire for a PC power supply that let you plug in an external battery for a cheap, long lasting UPS. But here are some other ideas.

We've gotten used to a painful, privacy invading security process when we fly. But why should we do this for shot-hop, small aircraft. Those ones on the 20 seat Canadair Business Jets and similar. Secure the cockpit with a sealed door and arm the pilot so that terrorists can't take control of the plane. Put in sealed transponders so ATC knows if the plane goes astray. Give the pilot a "disable" button that limits what can be done with the plane in the event of attempted hijack.

I like fine camera lenses, but the best quality are very expensive. There are many things that are hard to do in a good lens -- you want a sharp image, of course, over the full flat plane. Over the whole image plane you want low flare, high contrast and low chromatic abberation (ie. red and blue focus in the same spot.) And you want low distortions.

Most camera lenses try to be "rectilinear." That means they try to make a straight line straight in the image. This isn't actually natural, due to perspective straight lines are not straight.

So I wonder if we might soon see a new lens where no effort is made to fix distortions or make the image rectilinear, and all effort goes into the other factors. You are thus expected, with every image, to do digital post-processing to get a non-distorted rectilinear image. That will mean some small loss of image quality at the edges of the image, but probably a less distorted image than ordinary lens physics can deliver -- and a lot less cost -- in exchange.

Of course, this would primarily be for digital cameras, but a film user could also use the lens if they planned to scan their film for digital processing, as most do these days.

Down the road, each lens might contain within it the specifics of its own particular distortions, and the camera might be able to fetch this and either process directly or store it with the image for post-processing. Indeed, the lens might be a cheaply made lens with distortions due to the poor quality elements, or it might be a fine lens with deliberate distortions. (I have wondered if some P&S digicams might be doing this already.)

A lot of our democratic process involves our elected officials voting and presiding over things that voters are not going to change their vote over. Oh, they are important things, and the voters actually do care about them, but they are not going to change many votes.

That's especially true now. In deciding whether to re-elect your congresscritter, is how they voted on say FCC spectrum policy going to make a difference to you, compared to their stance on bigger issues like the war and the economy? Even when spectrum policy matters a lot to you?
