Earlier, I wrote in the post All you need is love of a philosophy of A.I. design, which I will call "Lennonism," where we seek to make our A.I. progeny love their creators.

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.

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.

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.

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.

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.

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.

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.

We need renewable energy, such as solar power. Because of that, companies are working hard on making it cheaper. They can do this either by developing new, cheaper to manufacture technologies, cheaper ways of installing or by simply getting economies of scale as demand and production increase. They haven't managed to follow Moore's law, though some new-technology developers predict they someday will.

The latest tome -- and at 900 pages, I mean tome -- from Neal Stephenson (author of Snow Crash, the Diamond Age and Cryptonomicon) is Anathem. I'm going to start with a more general review, then delve into deep spoilers after the jump.

This book is highly recommended, with the caveat that you must have an interest in philosophy and metaphysics to avoid being turned off by a few fairly large sections which involve complex debate on these topics. On the other hand, if you enjoy such exploration, this is the book for you.

Anathem is set on a planet which is not Earth, but is full of parallels to Earth. The culture is much older than ours, but not vastly more advanced because on this world scientists, mathematicians and philosophers live a cloistered life. They live in walled-off communities called Concents, with divisions within which only have contact with the outside world, and with each other, for one 10 day period out of each year, decade, century or millennium.

As such the Avout, as they are called, lead a simple life, mostly free of technology, devoted to higher learning. It's a non-religious parallel to monastic life. In the outside "saeclular" world, people live in a crass, consumer-oriented society both like and unlike ours.

I give the recommendation because he pulls this off really well. Anathem is a masterwork of world-building. You really get to identify with these mathematical monks and understand their life and worldview. He really builds a world that is different but understandable.

One way he does this, which does frustrate the reader at first, is through the creation of a lot of new coined terms. Some terms are used without introduction, some get a dictionary entry to help you into them. The terms are of course in a non-Earth language, but they are constructed from Latin and English roots, so they make sense to your brain. Soon you will find yourself using them.

So, if you like clever, complex worldbuilding and the worlds of science and philosophy, this book, long as it is, is worth it for you. However, I will shortly talk about the ending. Stephenson has a curse -- his world building is superb, and his skill at satisfying endings is not up to it. Anathem actually has a decently satisfying ending in many ways -- better than he has done before. There is both an ending to the plot, and some revelations at the very end which make you rethink all you have read before in the book. This time, I find fault with the consistency of the metaphysics, and mainly because I have explored the same topic myself and found it very difficult to make it work.

It's not too much of a spoiler to say that after we are shown this remarkable monastic world, events transpire to turn it all upside-down. You won't be disappointed, but I can't go further without getting into spoilers. You will also find spoilers in my contributions to the Anathem Wiki. That Wiki may be handy to you after you read the book to understand some of the complex components.

Two disturbing trends are moving upwards in the area of blog comment spam.

You may want to note that I have changed the challenge question for posting comments on this blog. It is no longer my last name.

I've written a few times about the "Selfish Merge" problem. Recently, reading the new book Traffic: Why We Drive the Way We Do by Tom Vanderbilt, I came upon some new research that has changed and refined my thinking.

The selfish merge problem occurs when two lanes reduce to one. Typically, most people try to be "good" and merge early, and that leaves the right lane, which is ending, mostly vacant. So some people zoom ahead of everybody in the right lane, and then merge at the very end. This is selfish in the sense that butting into any line is selfish. Even if overall traffic flow is not reduced (and even if it is increased) the person butting in moves everybody back one slot so they can get ahead by many slots. This angers people and generates more counter-productive behaviour, including road rage, and attempts to straddle the lanes so that the selfish mergers can't move up to the merge point.

In Traffic, Vanderbilt writes of surprising research that changed his mind, which showed that, in simulations, some merging forms provided up to 15% more traffic throughput than proper attempts at a zipper merge. In particular, a non-selfish merge fully using the vanishing lane worked better than the typical butt-in situation described at the top.

In this merge, which I'll call the "slow and fair merge," drivers are told to use both lanes up to the merge-point, and then to fairly "take their turn" at the merge point entering the continuing lane. Nobody is selfish here, in that nobody butts ahead of anybody else, but both lanes are fully utilized up to the merge point.

This problem is complex, I believe, because there is a switch-over point, which I call the "collapse" point. This is the point at which the merge flow becomes high enough that traffic collapses to "stop and go" mode, before and at the merge-point. Before that point, in lighter traffic, there is little doubt (for reasons you will see below) that the "cooperating fast zipper" merge results in the best traffic flow. In particular, there are traffic volumes where you could either have cooperating zipper or "slow and fair" but cooperating zipper would do a fair bit better. There are also traffic volumes where cooperating zipper just isn't possible any more, and we will either have "slow and fair" (which has the best volume) or "selfish merge" which has a worse volume.

Real world experiments show different results from the theoretical. In particular, many drivers, used to the anarchic selfish-merge approach, don't understand fair and slow, even when signs are explicit about it, and so they resist using both lanes and try to merge early. They also try to straddle, devolving to selfish merge. An experiment with digital signs which changed from advising drivers to zipper-merge in light traffic to advising "use both lanes" and "merge here, take your turn" in heavier traffic was disobeyed in fair and slow mode by too many drivers. The experiment ended before people could learn the system.

This week, as part of a 3-part series on the future of driving, ARS Technica has written a feature article derived from, and covering my series on Robocars. While it covers less than I do here, it does present it from a different perspective that you may find of interest.

I have tripods with both 3 segments and 4 segments. A 4-segment tripod has 3 clamps per leg, which means 9 of them to open and close in extending and collapsing the tripod. That's a pain. Enough of one that you sometimes find yourself asking whether a shot is worth setting up the tripod. But even 3 segment tripods are only a bit better.

Some upcoming events I will be involved in:

Burning Man Decompression, Sunday Oct 12

As I have for the past several years, I will show off my newest giant photographs of Burning Man at the "decompression" party, which takes place from noon to midnight on Sunday, Oct 12 (this coming Sunday) on Indiana St. south of Mariposa in San Francisco.

Ford is making a new car-limiting system called MyKey standard in future models. This allows the car owner to enable various limits and permissions on the keys they give to their teen-agers. Limits included in the current system include an 80 mph speed limit, a 40% volume limit on the stereo, never-ending seatbelt reminders, earlier low-fuel warnings, audio speed alerts and inability to disable various safety systems.

The worst thing about political debates occurs when the candidates break into their canned speeches, often repeating ones they had done before, and often when they have very little to do with the question that was asked. This happens because the candidates' teams, in negotiating debate rules, want it to happen. They want a boring debate, because they know that while it's hard (but not impossible) to win an election with a great debate performance, it is certainly easy to lose one with a bad one. So they avoid risks.

Coming up in a couple of weeks I will be speaking as a special guest at Alternative Party, a digital culture conference in Helsinki, Finland. I'll be doing my main talk on October 25th plus an extra session on either the 24th or 26th depending on schedules.

After that I will head to do some touristing in Stockholm for a few days, then for my first trip to Russia to visit St. Petersburg on the 31st.

Have some recommendations in Stockholm or St. Petersburg area? Let me know. My hosts will take care of me in Finland.

I've added a new Robocars article, this time expanding on ideas about how parking works in the world of robocars. The main conclusion is that parking ceases to be an issue, even in fairly parking sparse cities, because robocars can do so many things to increase, and balance capaacity.

Most of us have had to stand in a long will-call line to pick up tickets. We probably even paid a ticket "service fee" for the privilege. Some places are helping by having online printable tickets with a bar code. However, that requires that they have networked bar code readers at the gate which can detect things like duplicate bar codes, and people seem to rather have giant lines and many staff rather than get such machines.

Can we do it better?
