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?

Readers of this blog will know I used to talk a bit about Personal Rapid Transit (PRT) but have switched to a belief that it is now likely that robocars might fulfill the PRT vision before actual PRT can. To understand that, it is necessary to explore just why PRT has never really come about, in spite of being promoted, and possible for almost 40 years.

A friend (Larry P.) suggested that the time was here for serious (ie. DSLR) cameras to undertake a design revolution. The old SLR design, with a mirror that flips up and must sit between the last lens element and the sensor, creates a lot of problems in designing the lens and camera systems. Yes, being able to view directly through the lens with your eye is a very useful thing. But at what cost?

As a Canadian, and one of libertarian bent, I hope I have a better perspective on the two parties in the USA. What I see does not bode well for the Democrats. I think they understand the Republican side poorly, worse than the Republicans understand them. And, over the last two elections, they have shown little willingness to learn about it.

The law is full of defaults, as it is supposed to be. Some are in statutes, some are the result of many years of history of common law. They define the duties that people have in many ordinary transactions.

In my previous post, I noted that I had not done many night panoramas of Burning Man. I thought I should outline just why they are such a challenge.

Back from Burning Man and still dusty, here are five large panoramas to give you a sense of it.

It's amazing how much preparation is required for Burning Man. Or at least if you are crazy like me and plan to spend 11 days there, have 4 art projects, manage a new camp and still survive.

NBC has had just a touch of coverage of Michael Phelps and his 8 gold medals, which in breaking Mark Spitz's 7 from 1972 has him declared the greatest Olympic athlete, or even athlete of all time. And there's no doubt he's one of the greatest swimmers of all time and this is an incredible accomplishment. Couch potato that I am, I can hardly criticise him.

Photographers constantly debate about jpeg. Should they shoot in RAW or JPEG, for example. RAW preserves everything, but is much harder and bulkier to work with, so you will see serious pro photographers, who you think would always vote for the "never throw away" logic of RAW, tell you they work mostly in JPEG. I'm one of them. I use raw only for shots with high dynamic range, like night photography, and often shoot RAW+JPEG to work with the JPEGs and pull the RAWs if you need it.

Ok, this is something I have to believe somebody else has thought of, but I haven't seen it, so I thought I would ask readers if they have, and if not, to put it forward.

Everybody has a socket wrench set. The wrench heads tend to come with a square hole in the top, typically 1/2" or 3/8" square, into which the square drive from the ratchet inserts. There are sometimes spring-locks to keep it in place.

I've just returned from Denver and the World Science Fiction Convention (worldcon) where I spoke on issues such as privacy, DRM and creating new intelligent beings. However, I also attended a session on "hard" science fiction, and have some thoughts to relate from it.

Defining the sub-genres of SF, or any form of literature, is a constant topic for debate. No matter where you draw the lines, authors will work to bend them as well. Many people just give up and say "Science Fiction is what I point at when I say Science Fiction."

You may not know it, but any cell phone -- whether it has an account with a carrier or not -- is able to call 911. You can leave one of your old phones (and a car charger) in your car if you just want a way to reach emergency services.

There's a bit of an internet buzz this week around a video of a law lecture on why you should never, ever, ever, ever talk to the police. The video begins with the law professor and criminal defense attorney, who is a good speaker, making that case, and then a police detective, interesting but not quite as eloquent, agreeing with him and describing the various tricks the police use every day with people stupid enough to talk to them.

I often rant here about the need for better universal power supply technology. And there is some progress. On a recent trip to Europe, I was astounded how much we took in the way of power supply gear. I am curious at what the record is for readers here. I suggested we have a contest at a recent gathering. I had six supplies, and did not win.

Here's what the two of us had on the German trip in terms of devices. There were slightly fewer supplies, due to the fact several devices charged from USB, which could be generated by laptops or dedicated wall-warts.

• My laptop, with power supply. (Universal, able to run from plane, car or any voltage)
• Her laptop, with power supply.
• My unlocked GSM phone, which though mini-USB needs its dedicated charger, so that was brought
• My CDMA phone, functioning has a PDA, charges from mini-USB
• Her unlocked GSM phone, plus motorola charger
• Her CDMA Treo, as a PDA, with dedicated charger
• My Logger GPS, charges from mini-USB
• My old bluetooth GPS, because I had just bought the logger, charges from mini-USB
• My Canon EOS 40D, with plug in battery charger. 4 batteries.
• Her Canon mini camera, with different plug in battery charger. 2 batteries.
• Canon flash units, with NiMH AA batteries, with charger and power supply for charger.
• Special device, with 12v power supply.
• MP3 player and charger
• Bluetooth headset, charges from same Motorola charger. Today we would have two!
• External laptop battery for 12 hour flight, charges from laptop charger
• Electric shaver -- did not bring charger as battery will last trip.
• 4 adapters for Euro plugs, and one 3-way extension cord. One adapter has USB power out!
• An additional USB wall-wart, for a total of 3 USB wall-warts, plus the computers.
• Cigarette lighter to USB adapter to power devices in car.

That's the gear that will plug into a wall. There was more electronic gear, including USB memory sticks, flash cards, external wi-fi antennal, headsets and I've probably forgotten a few things.

There are a variety of tools out there to help recover stolen technological devices. They make the devices "phone home" to the security company, and if stolen, this can be used to find the laptop (based on IP traceroutes etc.) and get it back. Some of these tools work hard to hide on the machine, even claiming they will survive low level disk formats. Some reportedly get installed into the BIOS to survive a disk swap.

Last weekend I had a great trip to Wyoming, staying in Jackson for a bit and then into Yellowstone with a Cody side-trip.

As always, tons of photos and a new gallery of panoramic photos of the area. My last trip to Yellowstone featured poor weather and a very early (low quality) digital camera so I was pleased to photograph it again.

Last weekend I attended a small gathering in the Grand Tetons where Boone Pickens came to promote his new energy plan. The billionaire oilman is spending $56M of his own money per year on ads for this plan, and you will see them if you watch ads. Otherwise they are at his Pickens Plan web site.

This special chapter in my series of essays on Robocars describes a fictional week in the Robocar world, with many created examples of how people might use Robocars and how their lives might change.

If you haven't been following my essay on Robocars, this may be a good alternate entry to it. In a succinct way, it plays out many of the technologies I think are possible, more about the what than the how and why.
