New BCEC convention center, yet unwired

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?

The phone number is dead

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.

Upcoming conferences and speaking

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.

Hybrid RVs, more RV notes

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.

Playa phone at Burning Man

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...)

Adsense and the advertising/editorial wall

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.

Is strong crypto worse than weaker crypto? Lessons from Skype

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...

Bar Camp

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.

Universal laptop power supplies for desks, conference tables

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.

Monalithism

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.

Can we stop the loud-beep on backing up?

One of the scourages of urban areas is the requirement (I presume) that heavy equipment make a loud beeping noise when it's backing up. It's meant to warn anybody standing behind the vehicle, presumably because the driver doesn't have the same field of vision to see you, and because people are more wary of standing in front of a moving vehicle than behind it.

How about a Hugo Award for Science Fiction?

As some will know, I got heavily into the Hugo awards 13 years ago during my efforts at becoming an eBook publisher in the SF field. The Hugo award is voted on by the fans who attend the annual World Science Fiction Convention, or Worldcon, a moderately small voting pool (under 1000 of the typical 4000 to 7000 attendees will vote.)

The most important award and 2nd most voted on is the one for best Novel. The least important, but most voted on award is the one for best movie.

But still, for a long time, though both SF and Fantasy qualified for the award, the best Novel went exclusively to Science Fiction (with one dab into alternate history by Phillip K. Dick) and usually to hard, ideas-based SF. This went on until 2000 when the superb hard-SF novel "A Deepness in the Sky" won. The drama award was also heavily into SF, though it had some deviations, such as the coverage of Apollo XI and a few films in the 80s.

But in 2001, for the first time, a Fantasy novel won the best novel Hugo. Not just any fantasy novel, but a children's novel, Harry Potter 4. Of course, the Harry Potter series is the most remarkable success not just in fantasy, but in publishing, so this is not too shocking. What's surprising is that in 2002, 2004 and 2005 a fantasy novel would win best novel. At the same time, fantasies won all the best movie awards and all of the new best TV episode award until 2005.

Electric cars, perhaps not, but let's see more electric trikes

I recently picked up a surplus battery-powered motor assist for a bicycle, and it's a lot of fun. Due to lower power you have to start peddling to 3mph and then it can run the bike for 10 miles at 10mph (for normal weight people, not me.)

Editing down the funnies to those actually funny

Newspapers won't like this idea, but the truth is that most of the funnies aren't funny, certainly not every day. There are some talented people doing comic strips, but it's hard to do on a 7 days a week schedule, so they are almost all inconsistent.

Linux tester and linuxator for donated computers

A lot of older computers that people are ready to throw away can be decent linux boxes, in schools or in other charitable locations.

Sensing fog on the windshield

I'm not the first to think about it, since I see a bunch of patent filings related to it, but how hard would it be to have a sensor for windshield fog. Seems to me you could bounce light (UV perhaps which water scatters, though other colours might work) off the windshield to detect if there's fog on the inside and use that to control the defogger.

Pre-order drinks for intermission

In this new category, "What a great idea" I will document interesting ideas I have seen in my travels. Things that make you go "why didn't I think of that?" Some may be new, others just new to me.

At a recent symphony concert, I came out at intermission to see a table laid out with drinks and snacks, each with a little numbered placard. People had placed and prepaid orders before the show, and thus could get their drink without any line.

How a software monopoly arose

Recently, Joel on Software wrote an essay on good programmers and how they are qualitatively different from average ones. This is not a new realization, and he knows it and references sources like "The Mythical Man Month." It was accepted wisdom decades ago that a small team of really brilliant programmers would make a better product than a giant team of lesser ones.

Use GPS Maps to improve map databases, but protect privacy

Mapping programs, and fancy GPSs come with map databases that will, among other things, plot routes for you and estimate the time to travel them. That's great, but they are often wrong in a number of ways. Sometimes the streets are wrong (missing, really just a trail, etc.) and they just do a rough estimation of travel time.
