In my quest over the leak/sale of the entertainment.com mailing list, I have some amusing updates.

After telling them you don't respond to a "You sold my name" complaint with a request for all of the person's personal information, I got back yet another stock message, "Here's how you can get off our mailing list." I'm getting a lot of companies who use customer service reps for E-mail who clearly never read the E-mails. Yes, I also get software that auto-responds, but amazingly we also get humans who auto-respond.

Creationists regularly complain that schools teach evolution improperly and should also offer creation science as an alternative. They went so far as to push one school board to put stickers on biology textbooks remindng students that evolution is a theory and should be critically viewed.

When I give an E-mail address to a web site, I give a different one to each site. I have many domains, including one where all addresses are forwarded to me unless I turn them off.

I have been building an HDTV PVR with MythTV and the pcHDTV tuner
card. It's been a major adventure, not yet ready for prime time, but
it's lead me to have some thoughts about things you want to think about
in a PVR that particularly relate to HDTV.

For people of my generation, a great deal of history was seen on regular low-resolution TV. But a lot of it, up to the 70s or so (and often after) was shot on film, at higher resolution. Older generations saw some of this (once or twice) in newsreels at the movies.

So as HD sets become common, it would be great to see this old film footage of events like the wars, the Olympics, famous speeches, the moon landing and other space program material in high definition. I saw a DVD of the 1936 Olympics on a good screen and even that was surprising.

A short note, as I've been busy with a number of things including trying out PC based HDTV recording and mythtv, which I will write about shortly.

In a VoIP pricing debate, I calculated an interesting observation. Today we have voice codecs that can do very fine voice quality in about 25 kilobits. FM radio quality. Cell phone quality can be done in 7 kilobits. Anyway, that means all 200 million adult Americans could be on the phone at once and it would use 5 terabits.

This is a science-fictional idea, but strikingly probable. You are probably aware the brain is split into two halves, joined by a nerve bundle called the corpus callosum. People with severe epilepsy have had the callosum severed, and ended up having two brains in one body. A left brain controlling the right half, and a right brain controlling the left half. The left brain can speak and can lie, the right brain can write with the left hand to communicate.

There are a number of Linix "Live CD" distributions out there. These allow you to boot Linux from a CD and run it (somewhat slowly) without ever touching the hard disk in the machine. (They can access the disk however, which makes them good for system repair, both for Linux and Windows.) One popular one is Knoppix, and Mandrake makes one called MandrakeMove, which takes the important next step of letting you store your personal config choices on a USB thumbdrive or floppy.

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.
