There have been many efforts at internet "identity" systems, such as Microsoft Passport, Liberty Alliance, and a variety of others. A recent conference was held in SF, though I didn't go, but I thought it was time to put forward one important idea.

I've written before about the dichotomies between serial and browseable, between writer-friendly and reader-friendly.

One idea that now seems obvious is to integrate wiki functions into a mailing list manager (particularly one that does a web interface to the mailng list.)

On both a personal and professional note, I am happy to report that the federal courts have unanimously ruled to strike down the FCC's broadcast flag (that's a PDF) due to our lawsuit against them.

Update: A more active thread on how this relates to Goodmail and other attempts at sender-pays traffic

There is much talk these days of "who invented the internet?" Most of the talk is done wearing a network engineer's hat, defining the internet in terms of routing IP datatgrams, and TCP. Some relates to the end to end principle with a stupid network in the middle and smart endpoints. These two are valid and vital contributions, and recognition for those who built them is important.

But that's not what the public thinks of when it hears "the internet." They think of the collection of cool applications they use to interact with other people and distant computers. Web sites and mailing lists and newsgroups and filesharing and VoIP and downloading and chat and much more. Why did these spring into being in this way rather than on other networks?

I believe a large and necessary ingredient for "the internet" wasn't a technological invention at all, but a billing system. The internet is based on what I call the "internet cost contract." That contract says that each person pays for their own pipe to the center, and we don't account for the individual traffic.

"I pay for my half, you pay for yours."

While the end-to-end design allowed innovation and experimentation, the billing design really made it possible. In the early days of the internet, people dreamed up all sorts of bizarre applications, some serious, some entirely frivolous. They put them out there and people played with them and the most interesting thrived.

Many other networks had users paying not by the pipe, but based on traffic. In that world, had you decided to host a mailing list, or famously put a webcam up in front of your company fishtank, the next day the company beancounter would have called you into the office to ask why the company got a big bandwidth bill in order to show off the fishtank. The webcam -- or FTP site or mailing list -- would have been shut down immediately, and for perfectly valid reasons.

Pay-based-on-usage demands that applications be financially justifiable to live. Pay-per-pipe allowed mailing lists, ftp sites, usenet, archie, gopher and the web to explode.

While for various reasons I believe that the efforts to enforce E911 requirements on Voice over IP phones are bogus and largely designed to make it harder for smaller players to compete with established companies, there is a legitimate need for ways to give your location to emergency services.

George W. Bush names Jesus as the philosopher he admires the most. The most central of the teachings of Jesus can be found in the Sermon on the Mount.

I have come upong Bush's edited version of the sermon, amended to make the dictates of his Saviour easier to follow in these modern times.

Enjoy here in the Sermon on the Mount (George Bush Version)

During the 1990s, the US Government made a major effort to block the deployment of encryption by banning its export. We won that fight, but during the formative years of most internet protocols, they made it hard to add good authentication and privacy to internet tools. They forced vendors to jump through hoops, made users download special "encryption packs" and made encryption the exception rather than the norm in online work.

When people watch TV with a hard disk video recorder, they always watch the show delayed, often by hours or many days. They all watch it at a different time.

Dear [[blog-reader's name]]:

When it first started arising, in the 60s and 70s, everybody thought it was so cute and clever that computers could call us by name. Some programs even started by asking for your name, only to print "Hi, Bob!" to seem friendly in some way.

And of course a million companies were sold mailing list management tools to print form letters, filling in the name of the recipient and other attributes in varous places to make the letter seem personal. And again, it was cute in its way.

It seems that whenever you have a popular event, notably concerts in smaller venues and certain plays, the venue sells out their tickets quickly, and then ticket speculators leap in and sell the tickets at high margins. Ticket speculating (aka scalping) is legal in some areas and illegal in others. I don't think it should be illegal, but I wonder why the venues and performers tolerate so much of the revenue going to the speculators.

Linux distributions with package managers like apt, promise an easy world of installing lots of great software. But they've fallen down in one respect here. There are thousands of packages for the major distributions (I run 3 of them, debian, Fedora Core and Gentoo) but most packages depend on several other packages.

In this article about a wall-building robot we see another step towards automatic construction, moving the 3-D printer concept onto the grand scale. This is very interesting and could be expanded quite a bit. It notes that arms could add texture to ceramic walls, but I would go further.

Earlier I reported on Peerflix, which is implementing a P2P DVD sharing system with similarities to some of my own ideas. I have tried it out a bit now, and learned a bit more. I also have updated experiences with Peerflix.

The web site is marked beta and still very buggy, which is bad, but my first try on the service was first-rate. I mailed off my first DVD, Eternal Sunshine of the Spotless Mind,

on Wednesday to somebody in San Jose (who almost surely got it today) and got the replacement for it -- by strange coincidence another memory-related movie called Memento in the mail today. That is faster than most of the services, though people like Netflix could be this fast if they decided to take the same step and trust you when you said you mailed a disk, rather than waiting for it to arrive.

All this is good, but there's still a killer flaw in the idea of actually selling the DVDs. All DVDs will have a limited lifetime of high-demand. As demand drops below supply, somebody holding the DVD at that time will get "stuck" with it, though you can fix that by being fast on the draw in agreeing to be the one to mail any new requesters that do come along.

Perhaps this is one of those ideas that some car has implemented and I haven't yet seen it. As many people know, in several years ago a number of cars arranged so that their interior lights would not go off immediately when you closed up the car. This gives you the ability to still see shortly after closing up the car and walking away.

Of course this also drives people nuts, because in many cases you can't tell if the lights stayed on because you didn't close a door properly, and you would end up waiting around to see if they would go off.

Death Valley normally gets 1.5" of rain a year, but this year it got over six, so we headed down the greatest spring wildflower show in 50 years and were not disappointed.

Here's a business idea for both mobile phone companies and people who operate those giant digital signs in public places (such as malls and the Times Square jumbotron.)

For the past couple of years, I've been mulling over an idea for a different kind of DVD "rental" company, similar in ways to the popular NetFlix. Now I have encountered a new company called Peerflix which is doing something similar. Is it annoying or vindicating to see somebody else run with something? :-)

So instead I will comment on Peerflix, which I am going to try out, and what I planned to do differently.

Here John Dunn suggests sending an AI to negotiate with any aliens we discover via SETI.

This raises an interesting question. If SETI worked, and we got a signal from an alien intelligence, and the signal was understood to be a description of a computer architecture and then a big long, and undecipherably complex computer program -- possibly an AI -- could we dare run it?

I have looked at a lot of image management programs, though not all of them, and been surprised that none match what I think should be a very common workflow. Sure, they all let you browse your photos and thumbnails of them, move them around, and rename them. And some let you do the functions I describe but usually doing them to a lot of photos is cumbersome because they only have a slow mouse interface or a poor keyboard interface.

Here's what I want to do, and right now use a combination of programs to make happen.

On a recent roadtrip, I did some "wardriving" where you scan for 802.11 (wifi) access points. Today they are everywhere. The scanning program lists the network name (SSID) as well as other information like the model of access point and whether it has encryption on. Often the SSIDs are informative, with the names of families and companies. Mine is an web address that would let a neighbour contact me.

All this happens because most access points transmit a regular "beacon" packet which lists their SSID and other information needed to connect to them. Seeing that the SSIDs were sometimes interesting, I wondered if we might do much more with a special beacon.

This beacon would deliberately tell you a bit about the access or location. It would contain a mixed XML/HTML packet with a variety of useful fields and general text. These could range from simple descriptions ("This access point belongs to Joe Smith, I'm a programmer") to information ("On this site, Paul Revere stopped on his ride to consult with local minutemen") to street directions ("Turn right to get to highway 101, left for downtown") to, of course, advertising ("We sell fresh fruit and have a special on plums today.")

In other words, a replacement for signs and billboards and markers. And perhaps much more. Access points would also talk about themselves, declaring, for example, if the owner is offering open internet access for free or for fee, or has a local database of information, and what classes of information are in the main text. The local lattitude and longitude for those without a GPS could be useful, along with local map data in a compact form.

Users could quickly get a program for their laptop (such as Netstumbler) to read and display such virtual annotations to the world as they drive. Primarily for passengers to use, of course. Eventually dedicated boxes would become available, and onboard car computers and GPS units could understand the protocol. Mass market access points would include a set-up screen in their web interface to let the owner enter the information beacon text and enable it. (Today some APs have open source firmware and an energetic programmer could do this right away.)

All of this might be both useful and entertaining. Children might enjoy reading all the random bits of information that flow by and stop asking "are we there yet?" The journey can become the reward. (Of course remember to look out the window sometimes.)

I can imagine vendors making a cheap solar powered access point that, during the day at least, sends out information beacons as soon as enough power is stored in the capacitors to send one. These could operate on a small, cheap solar cell (the more power, the more frequent the beacon) and be placed anywhere. "I'm an oak tree!"

Below, I will get into some technical issues and discuss the unanswered question, which is how to avoid abuse by excessive advertisement, spam and falsehoods.
