While we still have over a month to wait for the show, Sci-Fi channel is releasing clues and has made a site with a daily clue to tease the viewers. We will not see Caprica soon, as hoped so this may be what we get.
The first clue is interesting: “You have heard my voice countless times, yet you do not know my name.”
This points to two of the more interesting candidates: The virtual being and a metal Cylon. Well, we actually haven’t heard the voices of the metal cylons much in this series, but the older characters did, long ago. We don’t know who the “you” in this phrase is — it could be the audience, or a character like Baltar or Adama.
We don’t know the Virtual being’s name. Baltar sees it as a Six or a Baltar, Starbuck sees it as a Leoben. Six sees it as a Baltar. But it never does say its name. We all assume it’s one of the 7 but it clearly isn’t.
Other clues include a clip of Apollo making a joke about somebody being the final Cylon, but the name is silenced out. And audio of Kara making some discovery. The First Hybrid’s line (discussed much here) and a photo of a Cylon fetus. Is the Cylon fetus the one in Six, perhaps where the virtual being will be incarnated? Or was it Hera? Tough to have either be a character. It may be a scene of long ago.
There’s also been a lot of talk in the past few months from insiders. Aaron Douglas has said several long spoilers that are so explicit I believe them to be plants. Several executives and actors have told us the ending will be very satisfying, very well constructed. The fifth Cylon will not be an unknown or rarely seen day player. The clues seem to cancel out almost all the favourites. Let’s hope they deliver.

Like most post-election seasons, we have our share of recounts going on. I’m going to expand on one of my first blog posts about the electoral tie problem. My suggestion will seem extremely radical to many, and thus will never happen, but it’s worth talking about.
Scientists know that when you are measuring two values, and you get results that are within the margin of error, the results are considered equal. A tie. There is a psychological tendency to treat the one that was ever-so-slightly higher as the greater one, but in logic, it’s a tie. If you had a better way of measuring, you would use it, but if you don’t, it’s a tie.
People are unwilling to admit that our vote counting systems have a margin of error. This margin of error is not simply a measure of the error in correctly registering ballots — is that chad punched all the way through? — it’s also a definitional margin of error. Because the stakes are so high, both sides will spend fortunes in a very close competition to get the rules defined in a way to make them the winner. This makes the winner be the one who manipulated the rules best, not the one with the most votes.
Aside from the fact that there can’t be two winners in most political elections, people have an amazing aversion to the concept of the tie. They somehow think that 123,456 for A and 123,220 for B means that A clearly should lead the people, while 123,278 for A and 123 and 123,398 for B means that B should lead, and that this is a fundamental principle of democracy.
Hogwash. In close cases such as these, nobody is the clear leader. Either choice matches the will of the people equally well — which is to say, not very much. People get very emotional over the 2000 Florida election, angry at manipulation and being robbed but the truth is the people of Florida (not counting the Nader question) voted equally for the two candidates and neither was the clear preference (or clear non-preference.) Democracy was served, as well as it can be served by the existing system, by either candidate winning.
So what alternatives can deal with the question of a tie? Well, as I proposed before, in the case of electoral college votes, avoiding the chaotic flip, on a single ballot, of all the college votes would have solved that problem. However, that answer does not apply to the general problem.
It seems that in the event of a tie there should be some sort of compromise, not a “winner-takes-all and represents only half the people.” If there is any way for two people to share the job, that should be done. For example, the two could get together to appoint a 3rd person to get the job, one who is agreeable to both of them.
Of course, to some degree this pushes off the question as we now will end up defining a margin between full victory and compromise victory and if the total falls very close to that, the demand for recounts will just take place there. That’s why the ideal answer is something that is proportional in what it hands out in the zone around 50%. For example, one could get the compromise choice who promises to listen to one side X% of the time and the other side 100-X% of the time, with X set by how close to 50% the votes were.
Of course, this seems rather complex and hard to implement. So here’s something different, which is simple but radical.
In the event of a close race, instead of an expensive recount, there should be a simple tiebreaker, such as a game of chance. Again, both sides have the support of half the people, they are both as deserving of victory, so while your mind is screaming that this is somehow insane because “every vote must be counted” the reality is different.
This tiebreaker, however, can’t simply be “throw dice if the total is within 1%” because we have just moved the margin where people will fight. It must be proportional, something like the following, based on “MARGIN” being the reasonable margin of error for the system.
- If A wins 50% + MARGIN/2 or more, A simply wins. Likewise for B.
- For results within the margin, define an odds function, so that the closer A and B were to each other, the closer the odds are to 50-50, while if they were far apart the odds get better for the higher number. Thus if A beat B by MARGIN-epsilon, Bs odds are very poor.
- Play a game of chance with those odds. The winner of the game wins the election.
A simple example would be a linear relationship. Take a bucket and throw in one token for A for every vote A got over 50%-MARGIN/2, and one token for B for every vote they got over that threshold. Draw a token at random — this is the winner.
However, it may make more sense to have a non-linear game which is even more biased as you move away from 50-50, to get something closer to the current system.
This game would deliver a result which was just as valid as the result delivered by recounts and complex legal wrangling, but at a tiny fraction of the cost. The “only” problem would be getting people to understand (agree to) the “just as valid” assertion.
And the game would be pretty exciting.

I now have a gallery up of the panoramas from Stockholm, Sweden. While this was not the best time of year to be photographing that far north (except for the availability of fall colour) I generated a lot of panoramas of various sorts. The main reason was I am trying some new panorama software, known as AutoPano Pro. This software is one of the licencees of the interesting SIFT algorithm, which is able to take a giant pile of pictures, and figure out which ones overlap and setting up the blend. The finding algorithm isn’t as important to me, because I recently wrote a perl program that goes through my pictures and finds all the runs of portrait shots with fixed parameters taken over a short period of time, and that helps me isolate my panoramas. However, the auto blending, even for handheld shots, means that it’s a lot easier to put together a larger number of panoramas.
I will be doing a more full review of the software later. Unfortunately while this is great in finding and building panos, and does an automatic job a fair bit of the time, when it does goof up it’s harder to fix it, so no one tool is yet ideal. This software also does HDR and not just multi-row but random “shoot everywhere” panos so you may see more of these from me.
One difference — because this made it easier to assemble my lesser and redundant panos, I did assemble them, and they can be found on a page of extra panoramas of Stockholm.

I gave a few visits to the RoboDeveloper’s conference the past few days. It was a modest sized affair, one of the early attempts to make a commercial robot development conference (it’s been more common to be academic in the past.) The show floor was modest, with just 3 short aisles, and the program modest as well, but Robocars were an expanding theme.
Sebastian Thrun (of the Stanford “Stanley” and “Junior” Darpa Grand Challenge teams) gave the keynote. I’ve seen him talk before but his talk is getting better. Of course he knows just about everything in my essays without having to read them. He continues (as I do) to put a focus on the death toll from human driving, and is starting to add an energy plank to the platform.
While he and I believe Robocars are the near-term computer project with the greatest benefit, the next speaker, Maja Mataric of USC made an argument that human-assistance robots will be even bigger. They are the other credible contender, though the focus is different. Robocars will save a million young people from death who would have been killed by human driving. Assist robots will improve and prolong the lives of many millions more of the aged who would die from ordinary decrepitude. (Of course, if we improve anti-aging drugs that might change.) Both are extremely worthy projects not getting enough attention.
Mataric said that while people in Robotics have been declaring “now is the hot time” for almost 50 years, she thinks this time she really means it. Paul Saffo, last weekend at Convergence 08, declared the same thing. He thinks the knee of the Robotics “S Curve” is truly upon us.
On the show floor, and demonstrated in a talk by Bruce Hall (of Velodyne Lidar and of Team DAD in the Darpa Grand Challenges) was Velodyne’s 64 line high resolution LIDAR. This sensor was on almost all the finishers in the Urban Challenge.
While very expensive today ($75,000) Hall believes that if he had an order for 10 million it would cost only hundreds without any great advances. With a bit of Moore’s law tech, it could even be less in short order.
Their LIDAR sees out to 120 meters. Hall says it could be tuned to go almost 300 meters, though of course resolution gets low out there. But even 120 meters gives you the ability to stop (on dry road) at up to 80 mph. Of course you need a bit of time to examine a potential obstacle before you hit the brakes so hard, so the more range the better, but this sensor is able to deliver with today’s technology.
The LIDAR uses a class 1 (eye-safe) infrared laser and Hall says it works in any amount of sunlight, and of course in darkness. He also says having many together on the road does not present a problem and did not at the Urban Challenge when cars came together. It might require something fancier to avoid deliberate jamming or interference. I suspect the military will pay for that technology to be developed.
This LIDAR, at a lower cost, seems good enough for a Whistlecar today, combined, perhaps with tele-valet remote operation. The LIDAR is good enough to drive at modest urban speeds (25mph) and not hit anything that isn’t trying to hit you. A tele-valet could get the whistlecar out of jams as it moves to drivers, filling stations and parking spots.
These forecasts of cheap, long-range LIDAR make me very optimistic about Whistlecars if we can get them approved for use in limited areas, notably parking lots, airports, gated communities and the like. We may be able to deploy this even sooner than some expect.

I’ve written before about microphones and asking questions at conferences. Having watched another crazy person drone on and on with a long polemic and no question, this time on a wireless mic, I imagined a wireless microphone with a timer in it. The audio staff could start the timer, or the speaker could activate the microphone and start the timer. A few LED would show the time decreasing, and then music would rise up to end the question, like at the academy awards. (In a more extreme version, those who did not turn the mic back off would get a small electric shock which increased in voltage, making it harder and harder to hold the mic.)
However, you do want a way, if the question is really interesting, to let the person speak if the moderator wants them to. This would suggest the music should come from the sound board and be optional. The electroshocks, too.

Once they made rules that political ads had to specify who was sponsoring them, we started seeing a lot of ads that would say they were sponsored by some unknown organization with a good sounding name. You see this from all sides of the equation; everybody picks a name that sounds like they are for truth, justice and the American Way, and anybody against them is against those things.
But what does a name like the “League of Concerned Citizens” (I made this up) mean? Very little. So what if we extended the requirement that, at least in the political ads, the name had to talk about how many concerned citizens they represented. You might pay more attention to the “League of 84,000 concerned citizens” than a league of 25 of them.
The number would have to represent paying or contributing members, not just people who put their name on a petition. And even so, special interests would try to game it. But still, “The Sierra Club of 750,000” would hold more weight than “The union of 84 homeowners.”

Here are some notes based on my recent trip to Finland, Sweden and Russia. Not about the places — that will come with photos later — but about the travel itself.
The ferries between Helsinki and Stockholm are really cruise ships. It takes about 16 hours and is a very popular method of travel between the cities, especially for families. There is no really practical land route, and the competition keeps the prices of these things down. In addition, they play tricks to allow duty free shopping, and unlike many duty free shops which are just ripoffs, these ones are competitive and do a brisk business. I’m told they are also party boats, but due to jet lag I was asleep not long after the Smörgåsbord. Unlike most cruise ships, these have almost nothing included, not the sauna, not the food and probably not even the mandatory showing of Abba’s “Mamma Mia.”
Because it the boat left at sunset and I planned to be awake and above at sunrise for photography of the Swedish Archipelago, and the moon was new, I decided there would be nothing to see, and I took an inside cabin. I was surprised to learn that, even though I knew it was dark and largely featureless outside, it bothered me to be in the sealed room. I reiterate my call that ship inside cabins come with a TV showing a closed circuit view of the outside in the correct direction. If they are not ready to do that (this ship didn’t even have TVs) I think a light behind the curtains of the fake window which simulates, based on just the clock, what the light should be like outside, would actually still be a positive step.
Or, failing that, if they put internet in the rooms, people could display the closed circuit video on the screen they brought with them…
On a ship like this, the shower takes up a lot of a very small room while being very cramped anyway. While most people want a toilet in their room, some communal locker room showers might make sense for preserving space. Of course, you still need a lot of them as demand comes at the same time, but not quite as many.
I think I’ll go back to a window for my next cruise cabin. But not a balcony. I have found that when I’ve had a balcony I sat on it for an hour of the entire week, and it took a lot of space out of the cabin.
The nice thing about the overnight cruise, of course, is that it made the trip between cities happen at night, offering a near full day in each city on either end. The arrival is a bit late at 10am, but that time is spent on a cruise of the islands, which all Stockholm tourists want anyway. It made me wonder if it was possible to arrange that sort of travel among close coastal cities in the USA or Canada (Boston to DC?) but perhaps the seas are not as reliable. And of course there is the Jones Act.
For the tourist, it also means the cruise is one of your hotel nights, and it costs only a little more for two people than a typical Stockholm hotel.
Taxi in Stockholm
Arriving in Stockholm, I was advised I should take a cab to our hotel and it would cost under $20. I had to eat my own words about cab competition because I got into a predator cab in the line at the ferry terminal which charged 5 times the typical rates. A few blocks away we noticed the meter going up one SEK (13 cents) per second and asked the driver to stop. He got abusive and threatening, and with my luggage implicitly hostage, I paid $25 to be dumped on the street in the rain with 3 suitcases and no SEK. Turned out there was a subway stop not far away, though that’s no fun with lots of bags.
Turns out the cabs do have their prices on them in the window, and no Swede would hire such a cab, but tourists unaware of the system can be easy marks, so no surprise this cab was at the ferry terminal. I had written earlier that I don’t believe in the heavy Taxi regulation most cities have, though I had come so much to expect it I got burned. The main argument for the regulation is that you can’t shop while standing waiting to hail a cab, but I can now see another argument about it on taxis serving people who will not know the local markets.
Stockholm transit was quite good, and we got an unlimited pass so used it a lot, though in many cases a cab would have probably saved valuable time. But we were so burned by our first Stockholm taxi experience that we just never felt the desire to use one again until the trip to the airport, which we had the hotel arrange.
Transit in St. Petersburg
St. Petersburg transit is a very different experience. It’s cheap: Typical fare of 16-18 rubles (around 60 cents) for official transit, 23 rubles for private buses that are more common. It’s very heavily used. Oddly, there did not appear to be transfers. If you wanted to change from trolley to bus, you seemed to pay again, or so our host told us. While at the low price this should not be a problem, it does mean you’re more likely to walk if you only have to go one or two stops on the 2nd leg.
The subway (which is quite grand, a Soviet showpiece) was packed to the gills on Sunday afternoon. We didn’t ride it during rush hour, and I’m glad. The subway isn’t actually terribly useful for the city core where the tourist sites are, though there happened to be a stop near our nice B&B.
Transport to/from the airport is another story, with most services seeming to run 40 to 60 Euros, though our host arranged a private car (by which I mean, just some guy’s Volga) for 30 Euros. We didn’t try it, but there is also an ad-hoc private taxi system. Stick out your arm and a private citizen will come pull over and negotiate a price, if they are going your way.
As noted, our driver had a Volga, but generally the streets are full of foreign cars. The car everybody wants is a Corolla. Ford is making big inroads too, along with Hyundai.
Finnair is charging for soft drinks on board, that trend is growing. ?????? (Rossiya) airlines still uses paper tickets, that was strange and frustrating. United Airlines won’t let a Premier member upgrade on a United Flight if their ticket came from Lufthansa (which I needed to do to make the Finnair connection as UA doesn’t partner with them.)
When I got my HTC Mogul phone, it had a GPS inside it, but the firmware didn’t enable it. So while in Germany in January, I used an external bluetooth GPS which worked OK, if being a bit silly. After I got back I got a phone firmware upgrade, which enabled the internal GPS, which has been very handy since then. When I got back to Europe I discovered two annoying things:
- While the GPS does use assisted GPS from the cell towers to work faster in the USA, it is a full GPS able to work away from them. But not in Europe, where it refused to work, even when it could see 5 or 6 satellites. Some report getting the phone GPS to wake up after 10-20 minutes but it never did for me.
- Alas, when they enabled the internal GPS, they disabled the ability to use an external bluetooth GPS through the official WINCE GPS API. So I was worse off than before.
- While a few programs could use the external GPS because you could manually configure them to use a different port, the offline map program I had downloaded could not. This had a real cost, as I ended up taking a few wrong turns and taking a few wrong street cars without knowing which direction I was going.
So brickbats for Sprint/HTC for this bizarre configuration, and I hope they fix it.

I’m back from my 3-country tour that started with being guest of honour at Helsinki’s “Alternative Party” which introduced me to the Demoscene, something I will write about in some future blog posts. While I have much to say about this trip, and many gigs of photos, I thought I would start with some travel notes.
How to be nice to your guest
I don’t write this to fault the crew at Alternative Party. They were fine hosts, and great and friendly people. As a small, non-professional conference, they had to act on a budget, so they could not do everything a rich conference might do. And they did several of the things I list here as good ideas.
- Hire a local travel agent to assist the guest, and to manage payments for travel. You can give the guest the option of using their own favourite agent, but somebody who knows local stuff is always a plus. And you can control spending via your own agent, and don’t have to worry about reimbursement.
- If the guest pays some of their own expenses, reimburse as quickly as you can to make them feel good. While it’s rare, there are enough stories of guests who found out after the fact that something would not be reimbursed (including in fraudulent cases an entire trip) to provide enough jitters. Speaking fee doesn’t need to be paid as quickly because that’s a two-way street.
- Write up a local guide web page for all guests with local info and information on at-event process. Include the mobile phone numbers of local organizers so somebody can always be reached.
- If the guest is coming from another country, particularly another continent, offer them a local cell phone or local (possibly prepaid) SIM card. These are often dirt cheap and you may even have some spare. If the guest is coming with somebody else, offer two or more of such. USA guests may not own a phone that can work overseas, and many European phones won’t work in the USA/Canada. If they do work, calls are usually very expensive, both for you to reach them and them to call you. In many countries, there are providers who offer free or cheap “on-network” calling, so a pair of such cards or phones can be handy as walkie-talkies.
- If the guest likes, circulate word among conference organizers or even known attendees to see if somebody who is a fan of the guest would be willing to be a local guide or driver before/after the event. Having a local pick you up at the airport and answer questions is very friendly compared to sending a limo or taxi. If the guest wishes, also arrange a dinner at a nice restaurant with interesting people from the conference.
- Above and beyond any dinner, ask the guest what kinds of restaurants they like and prepare a list for them of some that are known to be good.
Hotels should do some of this
In St. Petersburg, we stayed at a very nice B&B. But I still had a few suggestions of inexpensive things that could improve life.
- As with the conference, hotels should make local phones and SIMs available to guests with only a modest profit margin. Program the hotel concierge into the SIM’s phonebook, too. My German prepaid SIM could not make calls in Russia (it worked in Finland and Sweden though at roaming prices) and while I could have bought a Russian SIM, shopping for this would have been time-consuming without knowing the language.
- Of course, providing wireless internet should be de rigeur. It has become essential to our travels as we read news, get weather and look up tourist information on the internet regularly. In addition, have some loaner computers available, both for those who don’t bring a laptop, and for couples who bring only one but who can then both do their E-mail at once.
- European hotels almost universally serve a couple by putting two single beds together. They then put two sets of single sheets on the bed, or a single duvet. These can’t be tucked in, and at least for me, it means they always come off. And it’s no good for cuddling as a couple. It would not be that expensive to also keep a modest number of full-bed sheets around for those who prefer that. The single duvets could still sit on top. I realize the European system may make housekeeping easier, but I find it highly annoying and I am sure many others do as well.
- Many hotels offer a laundry service at a very high price. (Often the cost of cleaning socks and underwear will exceed the cost of buying new ones at discount stores like Costco.) But for those that don’t, the hotel should offer the location of a nearby laundry that does “wash and fold” (ordinary laundry charged by the kilogram) and perhaps even have a relationship with them. Once a trip gets over 8 or 9 days, laundry is important but you don’t want to waste time on it.
