Recently I attended a panel that covered, among other things the universal service fund. This fund, which you usually see as an add-on on your phone bill, taxes urban phone users (through their interstate carriers) to subsidize local phone service for the poor, the rural, schools and health care. Sounds noble, but it collected over 5 billion dollars in 2002, and now the question has come about how to apply it to the internet now that people are making phone calls over the internet.

IPTV is the new buzzword for video over IP, in particular as it relates to DSL/phone companies wanting to compete with cable companies and give you TV using your DSL. (The cable companies are hard at work at giving you phone service over your cable modem.)

Recently, I discovered something that others have known for a while but many don't know. Namely that effectively all modern cars that say they should use Premium (high-octane) gasoline run perfectly fine on regular. Since the early 90s, cars have had more advanced carb/fuel-injector systems which adjust to the octane of the gas and don't knock. Like an idiot, I've been filling my car with premium. The engineers at all the major car vendors have confirmed this.

Klein Gilhousen, one of the founders of Qualcomm, proposed this evening at Gilder's Telecosm that cell phones be modified, if an emergency shuts down the towers, to do some basic mesh networking, not so much for voice, but for text messaging and perhaps pust-to-talk voice packets, as well as location information from their internal GPS if present.

At every conference I go to, with a few rare exceptions, we always see people wasting time fiddling with computers and projectors in order to show their presentation, which is (sadly) almost always in powerpoint. Many laptops won't switch displays until they see a monitor on the VGA port, which makes things take longer.

So how about a wireless protocol for sending presentations from laptops to projectors or a computer connected to the projector. Over 802.11 or bluetooth, presumably.

In recent times, I and my colleagues at the Foresight Nanotech Institute have moved towards discouraging the idea of self-replicating machines as part of molecular nanotech. Eric Drexler, founder of the institute, described these machines in his seminal work "Engines of Creation," while also warning about the major dangers that could result from that approach.

Recently, dining with Ray Kurzweil on the release of his new book The Singularity Is Near : When Humans Transcend Biology, he expressed the concern that the move away from self-replicating assemblers was largely political, and they would still be needed as a defence against malevolent self-replicating nanopathogens.

I understand the cynicism here, because the political case is compelling. Self-replicators are frightening, especially to people who get their introduction to them via fiction like Michael Chrichton's "Prey." But in fact we were frightened of the risks from the start. Self replication is an obvious model to present, both when first thinking about nanomachines, and in showing the parallels between them and living cells, which are of course self-replicating nanomachines.

The movement away from them however, has solid engineering reasons behind it, as well as safety reasons. Life has not always picked the most efficient path to a result, just the one that is sufficient to outcompete the others. In fact, red blood cells are not self-replicating. Instead, the marrow contains the engines that make red blood cells and send them out into the body to do their simple job.

Many are commenting on the gasoline shortages and price increases involved with hurricane evacuation and other emergencies. Some people can't get gas to get out of the city. Others full up giant tanks even when they don't need it. Stations raise prices as supply drops and demand increases, as per the normal rules of the market. Some suggest the stations be price-controlled to stop this, but that would only result in even more gas hoarding by the public.

The reason that eBay paid such a huge price for Skype has now become clear. There were several companies competing to buy Skype, and just before the bidding closed, eBay decided the best way to win was to place a giant bid just a few seconds before the end. (This might be known as bid skyping.)

When I left high school, I didn't look back. I have a few friends from HS, but mostly I found many more like minded people in university. That seems to be a male trait, in that more women seem to keep a circle of friends from HS than men do, but for those that find themselves at university, this is where the social circle that may stay with us our entire lives is formed.

Attending a convention in the new Boston Convention and Exhibition Center (BCEC) I found one thing very surprising. The show organizer had to install wireless APs all around the building on poles, with long wires leading to power and ethernet. How can a new convention center not already be set up for wireless?

Here at the VON conference, there's lots of talk about numbering. While SIP had a dream of calling people using an E-mail address, the market has delivered devices with numeric keypads only, particularly in the mobile space. So nobody uses SIP URLs or domain names of any kind, and everybody worries about mapping to and from numbers. (Another thing Skype mostly ignored.) The regulators try to regulate VoIP by claiming they have the power when it makes calls to and from the legacy PSTN with its numbers.

In addition to the EFF party, here are some upcoming conferences I will be attending and/or speaking at:

• Sunday, a half-day at Accelerating Change 2005, Stanford

• Monday, Sept 19th at 10pm, panel on CALEA Wiretap rules for VoIP, at Pulver Voice on the Net conference in Boston at The BCEC (not Hynes as I reported earlier) Convention Center. I'll be at the conference for most of the week.

Join us for a party.

When:  Sunday, October 2nd, 2005 at 5 p.m.

Where:  EFF Headquarters in San Francisco, 454 Shotwell Street, 94110

EFF is 15 years old this year, and we are going to celebrate! We're having an anniversary bash at our San Francisco headquarters on Shotwell Street on Sunday, October 2nd, 2005. The party starts at 5 p.m.

Every time I take an RV trip (ie. each Burning Man) I come up with more observations. The biggest one is that it cost $360 in gasoline to go from the bay area to the black rock desert, about 800 miles. And that's at a price still well below world price. The RV owner said he was planning to get out of the business, people no longer want to pay the gas price.

If you noticed a long break in the blogging, it's because I was at Burning Man. And while people do blog from Burning Man, it's not what you want to spend your time doing. I will have more entries in the future, but let me relate some stories of the network and the phone booth first.

Last year, we erected a free phone booth in the desert to great results. This year, it was going to be even better because of a plan for a new internet connection. In the past, John Gilmore had brought his satellite dish, which had all the latency and bandwidth limits of satellite. This year he splurged on getting a microwave link in, which will be even faster next year. Sadly, much of that money was wasted because we never got the "first mile" -- the on-playa 802.11 network -- operating at a satisfactory level. There was huge packet loss and jitter in most places, when it was up at all. Next time some of the money will go into better equipment and planning for the local network.

As such, the phone booth, located in our camp on 7:30, only worked intermittently and rarely with great voice quality. We eventually decided to sacrifice the aesthetic purity of a booth sitting in the desert, connected to nothing, and moved it on its wagon by trike to the center camp, home of the incoming microwave link. The we set it up on the street, with an ethernet wire snaking in. We were no longer wireless, but the voice quality was top notch. I wasn't able to spend much time with it but reports were that the line got very long at times.

In our own camp, you could tell if it was working or not based on whether there was a line. Even waiting for it to work was better than the 2-3 hour time investment of taking the bus to the phone booth in Gerlach.

Last year, I recounted the emotional experience people had using an unexpected and impossible phone to hear the voices of loved ones. This year, this was magnified by Katrina. I learned of Katrina, in fact, when people came to ask to use the phone to contact their relatives in NOLA. (Read on...)

You are probably familiar with Google adsense, which is providing the ads you see on the right hand side of this page. Adsense code examines the text of pages, and tries to match Google adwords bids against it. The publisher of the page gets some undisclosed share of the Google revenue.

A mantra in the security community, at least among some, has been that crypto that isn't really strong is worse than having no crypto at all. The feeling is that a false sense of security can be worse than having no security as long as you know you have none. The bad examples include of course truly weak systems (like 40 bit SSL and even DES), systems that appear strong but have not been independently verified, and perhaps the greatest villian, "security through obscurity" where the details of the security are kept secret -- and thus unverified by 3rd parties -- in a hope that might make them safer from attack.

On the surface, all of these arguments are valid. From a cryptographer's standpoint, since we know how to design good cryptography, why would we use anything less?

However, the problem is more complex than that, for it is not simply a problem of cryptography, but of business models, user interface and deployment. I fear that the attitude of "do it perfectly or not at all" has left the public with "not at all" far more than it should have.

An interesting illustration of the conflict is Skype. Skype encrypts all its calls as a matter of course. The user is unaware it's even happening, and does nothing to turn it on. It just works. However, Skype is proprietary. They have not allowed independent parties to study the quality of their encryption. They advertise they use AES-256, which is a well trusted cypher, but they haven't let people see if they've made mistakes in how they set it up.

This has caused criticism from the security community. And again, there is nothing wrong with the criticism in an academic sense. It certainly would be better if Skype laid bare their protocol and let people verify it. You could trust it more. Read on...

Just back from a day at Bar Camp which was quickly put together as a tongue-in-cheek response to Tim O'Reilly's Foo Camp and folks who had not been invited. Foo Camp is great fun, and Tim does it all for free, so it's not suprising he has to turn people away -- even me :-) -- but Bar Camp was surprisingly good for something thrown together at the last minute with no costs.

I've called before for a system of Universal DC Power and I still want it, but there is a partial step we could take.

I have a laptop power supply that comes with a variety of tips. The tips tell (through something as simple as a resistor) the power supply how much voltage and current to supply for the laptop they are designed for. I bought mine for use in an airplane, others are sold that do both 12v and AC power.

Hot in the blogosphere these days, as a result of the Creationism/ID vs. Evolution debate is Pastafarianism, the worship of the Giant Flying Spaghetti Monster. The idea is to show that something as made up as the GFSM is as consistent as ID.
