Frequently these days I will see some shocking statistic reported:
The top 1% of earners receive over 18% of all the income (or 23% including cap gains)
The top 5% sickest Americans account for half of all healthcare costs
These numbers suggest a shocking inequality. And there might even be an unusual inequality but you won’t see it from these numbers. What’s vital when people report things like this is that they outline what the ratio should be given what would be an expected distribution. You should expect the top 1% or top 5% of any unevenly distributed thing to be consuming a much larger share of the pie. That’s what it means to have an uneven distribution. If the top 1% of income earners only earned 1% of income, you would be in a communist utopia, and that’s true even if they earned 5%. That’s what it means to be one of the top earners.
To make this clear, I present the following statistic I suspect to be generally accurate: 99% of the fire insurance payouts in a given year go to the top 1% claiming policyholders. I have not got an actual source, but it is presumably the case because fewer than 1% of people have their house burn down. You would expect that the top 1% would get essentially all the fire insurance money in any given year.
So when you see a claim about distribution involving the top x% getting much more than x%, the right response is, “sounds normal, show me why this is unexpected or unusual.” It may well be, but you need the numbers to back it up.
A new robocar project named “Quasper” has emergence in France from the IRSEEM Esigelec lab and IFSTTAR. This vehicle uses a commercial actuator robot to control the wheel and pedals for drive-by-wire, and features a variety of typical sensors, though it only has a couple of smaller SICK LIDARSs rather than a high resolution LIDAR like the Velodyne used by many other projects. Their work is fairly basic for now. Because the DBW system occupies the driver’s seat, manual control is done through a joystick which controls the drive-by-wire robot. As a nice aesthetic touch, they have put much of the electronics in a standard roof box on top of their minivan. (Some of the early robocars did have a certain mad-science look with all their gear covering the roof.)
At the Consumer Electronics Show in Las Vegas this week, which I attended, most of the car announcements were for information and entertainment systems in cars. The one positive light is that many car vendors now realize they no longer can own and control all the digital systems in a car, and are making tools to connect with the driver’s phone and tablet for various purposes. They are not quite ready to use the phone as their data connection, though so most mean you will be paying for 2 data connections.
Mercedes and Audi had displays relating to ADAS and autonomous driving. While there was no sign of the Mercedes 2013 S class that will feature an autopilot, they did show a rather strange demo of a future self-driving car where the windshield was now a giant augmented reality screen. There, using hand gestures, you could point and objects in the real world and learn more about them. Of course, if your car is self-driving, you could use any interface, not just a gestural one. Today, gestural interfaces are not very well developed and most people prefer touchscreens and keyboards.
Audi showed their lane-keeping system and crash avoidance tools. While they didn’t make a deal about it, reports say they are planning to have a traffic-jam autopilot like the Mercedes one, but up to 60kph instead of just 40kph. This means combining their lane-departure-correction system, which steers you back into the lane using the steering motor, and their automatic cruise control which follows the car in front. It’s now up to Audio and Mercedes to see who comes out first. It will be very interesting, as well, to see how the public responds to it.
Mercedes is downplaying the value of a self-driving car. In a keynote by M-B boss Dr. Dieter Zetsche, he said the following (as reported by Motor Trend):
“We don’t believe that autonomous driving is the ultimate goal. We still want the driver to be in charge, in control, be the pilot. But when you are stuck in a traffic jam, when you are driving five hours straight through Nebraska, it might not be the most fun (to drive). And at that time you can switch and say, ‘Take over, I’ll read a nice book, look at movies, or listen to music.’ So it’s your choice, you’ll always be in control, but you have the choice to hand (the controls) over to an autonomous car.”
High end brands like Mercedes are in an uncomfortable situation. For a long time, they have sold their product based on the excitement of driving. They are torn between that message and the value of the robocar. My own prediction is that initially, people will indeed be keen on cars which do the boring driving, but take them to places where the driving is more fun. While fun driving will not go away, I predict people will start feeling that more and more driving is a chore to leave to the robot, and less and less is a thrill that demands taking the wheel. Look at how readily people who move to New York or other non-driving cities adapt to not driving. But that’s not a message sporty car brands will want to say. At the same time, self-driving will be a desired luxury feature and so luxury cars will have to offer it. The problem is that high end brands tend to offer both sport and luxury, often in the same vehicles.
Back to wishlists on credit cards: Every year, for tax time, I go over my downloaded credit card records and I classify them into categories. I could just try to divide out the business and personal expenses (which I handle by having credit cards for business only and for personal only) but I try to do a bit more categorization, and from time to time there’s a reason I don’t follow the strict rule about what card to use.
So I would like, when I do an online purchase, to have an optional field in the form in which I can type anything. This would get put in or added to the memo field that you get when you download your transactions into accounting software. A quick script could then turn these memos into the categories we need for accounting.
Since getting a new field in forms is a lot of work, card companies could also offer me a small set of similar card numbers, though there might be only one on the physical card. This could be used to do some very basic categorization on the same card. They would all download to the same account, but the last digit would show up in the memo field. I know there are cards that issued a new number for every internet transaction back in the more paranoid days, but I’m talking about a series of cards where only one digit changes (if accepted by the processors because they pass it fully along,) and I can fill in the digit I like for a given transaction. (If I wish I could also get another card made of course. In fact, that would be handy if I decide to get two cards on the same account when giving a sub-card to a family member but not wanting a completely independent account for them.)
Over the years I have come to the maxim that “Everything should be as secure as is easy to use, and no more secure” to steal a theme from Einstein. One of my peeves has been the many companies who, feeling that E-mail is insecure, instead send you an E-mail that tells you you have an E-mail if you would only log onto their web site (often one you rarely log into) with the password you set up 2 years ago to read it. I often get these for things like bills and statements — “Your statement is now available online.” A few nicer ones tell me that my statement is online but the e-maiil does contain the total in the statement. Only if the total is unexpected do I need to login to see the statement.
None of these sites seem to offer me the option of saying, “My E-mail is secure, at least if you are doing your job, so just send me the data in E-mail” or of using one of the end-to-end encrypted E-mail systems. Alas, there is more than one E-mail system, but it’s not hard to do the two most popular, PGP/GPG and S-Mime and they are fairly widely supported in mailers.
As I noted, my own mail is secure in that I run an SMTP server on my home server, and only access it over encrypted IMAP. If they have set up their server to do encrypted SMTP (which should be the default by now, frankly) then the mail is generally secure (though it does do a brief unencrypted stop at my spam filter system.)
However, somtimes the contents of the mail need no security, and so instead it’s just annoyance. I have an acccount with Wachovia bank, and yesterday got an E-mail that there was an “important, secure E-mail” I should read on their server. After logging in, I found that all they had to say was public information about their merger with Wells Fargo, and how accounts would be shifted over. There was no reason that needed to be secure, since the only secret to reveal was that I had an account there, and the E-mail revealed that.
So I wrote a note back to complain, telling them not to make me jump through hoops to read public information. What’s so much fun is the response I got back:
Thank you for contacting Wachovia. My name is Tulanee E, and I am happy
to assist you.
Mr. Templeton, I would be happy to assist you. However, to guarantee the

Like many, I go to a lot of conferences and events. And many of those events have decided that they should give everybody a bag. Most commonly it’s a canvas laptop sized bag, though sometimes it’s a backpack and at cheaper events just a tote. Some of the bags are cheap, some are quite nice. Some come with just the logo of the event on them, and others come festooned with many logos from sponsors who bought a space on the bag.
The bags are too nice to throw away, so I’ve kept most of them, usually tossing them in a storage crate. I decided to get the bags from the last decade out and lay them out for a photo. I’m guessing a lot of people have similar collections. We’re undergoing a serious bag spam problem.
I have used some of these bags but of course the vast bulk have either gone unused entirely, or were just used at the conference or just on the day they handed out the bag. Making the conference logo visible at the conference is pointless, though perhaps with the sponsored bags, all they want is to plaster their logo at the conference. It’s actually risky to use the conference bag at the conference, especially for things like your laptop, as it’s way too easy to mistake your bag for somebody else’s.
I don’t see other people using these bags much either. Sometimes on the flight back from the conference. Or if the conference is an invite-only conference that has some cachet to its sachet. It’s very rare to see people walking around with a bag with 6 sponsor logos on it. We conference-goers aren’t the type that like to be seen as carrying around somebody’s advertising, or being too cheap to buy our own briefcase.
This isn’t even the whole collection, there’s 50% more out there. I have actually used a few bags if I happened to particularly like their design, or they came from places I actually worked at. Messenger bags which wear comfortably on the body seem to meet my approval over yet more laptop briefcases.
And I have disposed of or given away a few, or they weren’t in the crate I put bags into.
If you’re getting ready to hand out a conference bag, here are some things to consider:
Realize that almost everybody you give a bag to has a box full of bags at home. Being a really nice expensive bag might help a little but it’s costly.
Face it, unless you are TED, the vast majority of the bags you give out are going to sit in storage. Consider something else. Just don’t do it.
If you feel you have to have a bag, also have an alternative schwag that’s just as valuable people can pick instead of a bag.
Consider the bold move of putting the logos on the inside flap of the bag. That gives up the exposure you were never going to get much of anyway, and makes it more likely I will use the bag, and be reminded of you every day — and possibly even remind some of the folks I meet with who see me open my bag.
Forget about putting 6 logos on the bag unless all you want is to plaster those logos around your show floor. You can’t even give those bags away.
If you must have a bag, go cheap with a tote, and make it a zippered tote. We can always find uses for those, they make decent reusable grocery bags, for example. Then I’ll keep them in the trunk and remember you on grocery trips. Or go fancy and make it an insulated grocery bag.
This is not to say you could not impress me with something clever, perhaps for a short time. For example I would not mind a bag that integrated a universal power supply and had retractable cords so I did not have to take it out. Or one of those new photographers sling backpacks that you can pull around to access stuff without removing the straps from your shoulder. But if you do that, soon somebody else will have it too and I’ll have a box of them.
So what other schwag can you give out? That is a challenge of course, and there’s a whole industry trying to sell you stuff. It varies with the time, and it has to be something new so that I don’t have a box of them at home. Consumable stuff (chocolate bars etc.) are always welcome but you fear that this means your logo will be forgotten. But it’s better than being in a crate. Travel stuff is usually a hit but duplication is again a risk — retractable cables etc. Or spend your money on a nice mobile schedule for your event, one that doesn’t suck (most of the ones out there suck) and put some logos on that.
I am told that homeless shelters like donations of backpacks and other useful bags. I suppose if we all did this, and companies found their logo hanging from the shoulders of homeless dudes, they might think twice about giving out so many bags. A system to arrange donation to poor folks in Africa might also be good.
Almost all credit cards will let you download transactions. Many will e-mail you a balance or payment reminder once a month, or a warning if your balance goes above a certain amount. And I’ve seen a small number that will e-mail you on every transaction.
But does anybody have a smart notification system which I can set, allowing me to be comfortable that there is no misuse of my card without filling my mailbox?
At a basic level, notification (email or SMS) of transactions above a certain amount
Combine that with notification when a group of small transactions exceed a set amount or an amount of time goes by (E-mail only)
“You don’t need to notify me of this transaction” for your repeating transactions
Easy console to turn on or off warnings and fraud alerts on foreign locations
For those of us who are on e-mail or SMS literally every day, this is a lot better fraud protection for us than the systems they use now, especially the one that find us with denied transactions in unusual places.
Update: Thanks to all commenters — some cards are providing many of these services.
Spokesmen for the MPAA, RIAA and several other content industry companies recently issued a statement of support for the new “Stop Airline Piracy Act” or SAPA, now before congress.
SAPA seeks to address the massive tide of copyright infringing material flowing into the USA on commercial airlines and delivery services. Today in China and many other countries, bootleg DVDs, CDs and software disks are being manufactured in bulk, and sold to visitors on the streets of these cities in illicit malls. Then, these visitors fly back to the USA with the pirate disks in their suitcases, taking them into the USA. Other Americans are ordering these pirate DVDs and having them shipped via both airlines and other shippers directly to their homes.
SAPA addresses this problem by giving content owners tools to cut down this pirate flow. A content owner, once they learn of an airline or shipping service which is regularly and repeatedly bringing pirated material into the country, can file claims alleging the presence of this infringement. The bill allows them to shut off the flow of money, traffic and customers to the airlines, by getting US companies to stop directing people to the airlines, and stopping payment services from transferring money to them.
“Last month, we worked with customs and border patrol to inspect planes coming into LAX from overseas,” said Pearl Alley, a spokesperson for the MPAA. “We found that every single plane of an unnamed airline had pirated material in passenger bags or in the hold. Not just a few planes, every single plane. Most planes had multiple pirated products, including DVDs and CDs, and files on laptops and music players.” Customs is able to seize any laptop or music player coming into the country for any reason and copy its drive to see what’s on it, according to CBP officials.
“These airlines and shippers are enabling and facilitating infringement. This has got to be stopped, and SAPA will stop it,” said Alley.
Under SAPA, an airline alleged to have been regularly carrying in pirated material can be blacklisted. Travel agents will be forbidden from booking passengers on the airline. Travel web sites can be ordered not to list flights or even the existence of the airline. Phone book and Yellow page companies can be ordered to remove any listings for the airline, and in some cases, phone switches can be ordered to not complete calls directed at airline phone numbers. Travel review books and sites can be ordered edited to delete mention of the airline or recommendations to fly on it.
To shut off the money flow, an accusation of alleged infringement under SAPA can result in an order to Visa, Mastercard, Paypal and other financial processors to not accept payments for the airline or shipping company. “They may be overseas, but we can stop them from destroying American jobs with tools we have at home,” said Senator Dianne Feinstein (D-CA), co-sponsor of the senate version of the bill.
Airports can also be prohibited from allowing the planes to land. However, planes in the air can file a counter-notice within 5 days of a claim, providing they subject themselves to US jurisdiction and agree to be liable if they are found to have copyright material in their holds. Aircraft which can’t file a counter notice are free to turn around on approach to LAX and return over the Pacific, but may not land at any airport in a country which has signed the Anti-Counterfeiting Trade Agreement with the USA.
“Legitimate Airlines, ones that are not carrying in pirated material every day, will not be harmed by this act, because of the counter-notice provision. In addition, if a rightsholder files a false claim, and there are no copyright violations on board the plane, the airline has a right to sue for damages over misuse of the act — so it’s all safe and does not block legitimate trade,” said Alley.
Several airlines, travel agencies and travel sites have, not surprisingly, filed opposition to this bill, but it is supported by a broad coalition of US job creators in Hollywood and Redmond, as well as domain name site GoDaddy.
This time of year I do a lot of online shopping, and my bell rings with many deliveries. But today and tomorrow, not Saturday. The post office comes Saturday but has announced it wants to stop doing that to save money. They do need to save money, but this is the wrong approach. I think the time has come for Saturday and Sunday delivery to be the norm for UPS, Fedex and the rest.
When I was young almost all retailers closed on Sunday and even had limited hours on Saturday. Banks never opened on the weekend either. But people soon realized that because the working public had the weekend off, the weekend was the right time for consumer services to be operating. The weekend days are the busiest days at most stores.
The shipping companies like Fedex and UPS started up for business to business, but online shopping has changed that. They now do a lot of delivery to residences, and not just at Christmas. But Thursday and Friday are these odd days in that business. An overnight package on Friday gets there 3 days later, not 1. (If you use the post office courier, you get Saturday delivery as part of the package, and the approximately 2 day Priority mail service is a huge win for things sent Thursday.) In many areas, the companies have offered Saturday and even Sunday delivery, but only as a high priced premium service. Strangely, the weekend also produces a gap in ground shipping times — the truck driving cross-country presumably pauses for 2 days.
We online shoppers shop 7 days a week and we want out stuff as soon as we can get it. I understand the desire to take the weekend off, but usually there are people ready to take these extra shifts. This will cost the delivery companies more as they will have to hire more workers to operate on the weekend. And they can’t just do it for ground (otherwise a 3 day package sent Friday arrives the same time as an overnight package.)
Update: I will point out that while online shipping is the David to the Goliath of brick & mortar, changing shipping to 7 days a week will mean a bunch more stuff gets bought online, and shipped, and will bring new revenue to the shipping companies. It’s just just a cost of hiring more people. It also makes use of infrastructure that sits idle 2 days a week.
This is particularly good for those who are always not hope to sign for packages that come during the work week. The trend is already starting. OnTrak, which has taken over a lot of the delivery from Amazon’s Nevada warehouse to Californians, does Saturday delivery, and it’s made me much more pleased with Amazon’s service. When Deliverbots arrive, this will be a no brainer.
Here the court held that Citizens United, a group which had produced an anti-Hilary Clinton documentary, had the right to run ads promoting their documentary and its anti-Clinton message. It had been held at the lower court that because the documentary and thus the ads advocated against a candidate, they were restricted under campaign finance rules. Earlier, however, the court had held earlier that it was OK for Michael Moore to run ads for Fahrenheit 9/11, his movie which strongly advocated against re-electing George W. Bush. The court could not find the fine line between these that the lower court had held, but the result was a decision that has people very scared because it strips most restrictions on campaigning by groups and in particular corporations. Corporations have most of the money, and money equals influence in elections.
Most attempts at campaign finance reform and control have run into a constitutional wall. That’s because when people talk about freedom of speech, it’s hard to deny that political speech is the most sacred, most protected of the forms of speech being safeguarded by the 1st amendment. Rules that try to say, “You can’t use your money to get out the message that you like or hate a candidate” are hard to reconcile with the 1st amendment. The court has made that more clear and so the only answer is an amendment, many feel.
It seems like that should not be hard. After all, the court only ruled 5-4, and partisan lines were involved. Yet in the dissent, it seems clear to me that the dissenters don’t so much claim that political speech is not being abridged by the campaign finance rules, but rather that the consequences of allowing big money interests to dominate the political debate are so grave that it would be folly to allow it, almost regardless of what the bill of rights says. The courts have kept saying that campaign finance reform efforts don’t survive first amendment tests, and the conclusion many have come to is that CFR is so vital that we must weaken the 1st amendment to get it.
With all the power of an amendment to play with, I have found most of the proposed amendments disappointing and disturbing. Amendments should be crystal clear, but I find many of the proposals to be muddy when viewed in the context of the 1st amendment, even though as later amendments they have the right to supersede it.
The problem is this: When they wrote that the freedom of the press should not be abridged, they were talking about the big press. They really meant organizations like the New York Times and Fox News. If those don’t have freedom of the press, nobody does. And these are corporations. Until very recently it wasn’t really possible to put out your political views to the masses on your terms unless you were a media corporation, or paid a media corporation to do it for you. The internet is changing that but the change is not yet complete.
Many of the amendments state that they do not abridge freedom of the press. But what does that mean? If the New York Times or Fox News wish to use their corporate money to endorse or condemn a candidate — as they usually do — is that something we could dare let the government restrict? Would we allow the NYT to do it in their newspaper, but not in other means, such as buying ads in another newspaper, should they wish to do so? Is the Fox News to be defined as something different from Citizens United?
I’m hard pressed to reconcile freedom of the press and the removal of the ability of corporations (including media ones) from using money to put out a political message. What I fear as that to do so requires that the law — nay, the constitution — try to define what is being “press” and what is not. This is something we’ve been afraid to do in every other context, and something I and my associates have fought to prevent, as lawsuits have tried to declare that bloggers, for example, were not mainstream press and thus did not have the same freedom of the press as the big boys. read more »
Earlier I wrote about desires for the next generation of DSLR camera and a number of readers wrote back that they wanted to be able to swap the sensor in their camera, most notably so they could put in a B&W sensor with no colour filter mask on it. This would give you better B&W photos and triple your light gathering ability, though for now only astronomers are keen enough on this to justify filterless cameras.
I’m not sure how easy it would be to make a sensor that could be swapped, due to a number of problems — dust, connectivity and more. In fact I wonder if an idea I wrote about earlier — lenses with integrated sensors might have a better chance of being the future.
Here’s another step in that direction — a “foveal” digital camera that has tiny sensors in the middle of the frame and larger ones out at the edges. Such sensors have been built for a variety of purposes in the past, but might they have application for serious photography?
For example, the 5d Mark II I use has 22 million 6.4 micron sensors. Being that large, they are low noise compared to the smaller sensors found in P&S cameras. But the full frame requires very large, very heavy, very expensive lenses. Getting top quality over the large image circle is difficult and you pay a lot for it.
Imagine that this camera has another array, perhaps of around 16 million pixels of 1.6 micron size in the center. This allows it to shoot a 16MP picture in the small crop zone or a 22MP picture on the full frame. (It also allows it to shoot a huge 252 megapixel image that is sharp in the center but interpolated around the edges.) The central region would have transistors that could combine all the wells of a particular colour in the 4x4 array that maps to one large pixel. This is common in the video modes on DSLR cameras, and helps produce pixels that are much lower noise than the tiny pixels are on their own, but not as good as the 16x larger big pixels, though the green pixels, which make up half the area, would probably do decently well.
As a result, this camera would not be as good in low light, and the central region would be no better in low light than today’s quality P&S cameras. But that’s actually getting pretty good, and the results at higher light levels are excellent.
The win is that you would be able to use a 100mm/f2 lens with the field of view of a 400mm lens for a 16MP picture. It would not be quite as good as a real 400mm f/2.8L Canon lens of course. But it could compare decently — and that 400mm lens is immense, heavy and costs $10,000 — far more than the camera body. On the other hand a decent 100mm f/2.8 lens aimed at the smaller image circle would cost a few hundred dollars at most, and do a very good job. A professional wildlife or sports photographer might still seek the $10K lens but a lot of photographers would be much happier to carry the small one, and not just for the saved cost. You would not get the very shallow depth of field of the 400mm f/2.8 — it would be about double with a small sensor 100mm f/2 — but many would consider that a plus in this situation, not a minus.
You could also use 3.2 or 2.1 micron sensors for better low-noise and less of a crop (or focal length multiplier as it is incorrectly called sometimes.)
One other benefit is that, if your lens can deliver it, and particularly when you have decent lighting, you would get superb resolution in the center of your full frame photos, as the smaller pixels are combined. You would get better colour accuracy, without as many bayer interpolation artifacts, as you would truly sense each colour in every pixel, and much better contrast in general. You would be making use of the fact that your lens is sharper in the center. Jpeg outputs would probably never do the 250 megapixel interpolated image, but the raw output could record all the pixels if it is not necessary to combine the wells to improve signal/noise.
In the case of the helicopter, which is still moving as it was just a regular tour helicopter, the challenge is to shoot very fast and still not make mistakes in coverage. I took several panos but only a few turned out. Victoria Falls can really only be viewed from the air — on the ground the viewing spots during high water season are in so much mist that it’s actually raining hard all around you, and in any event you can’t see the whole falls. One lesson is to try not to be greedy and get a 200m pano. Stick to 50 to 100mm at most.
On this trip I took along a 100-400mm lens, and it was my first time shooting with such a long lens routinely. I knew intellectually about the much smaller depth of field at 400mm, but in spite of this I still screwed up a number of panoramas, since I normally set focus at one fixed distance for the whole pano. Stopping down 400mm only helps a little bit. Wildlife will not sit still for you, creating extra challenges. I already showed you this elephant shot but I am also quite fond of this sunset on the Okavango delta. While this shot may not appear to have wildlife, the sun is beaming through giant spiderwebs which are the work of “social spiders” which live in nests, all building the same web. I recommend zooming in on the scene in the center. I also have some nice regular photos of this which will be up later.
I am still a bit torn about the gallery of ordinary aspect ratio photos. I could put them up on my photo site easily enough, but I’ve noticed photos get a lot more commentary and possibly viewing when done on Google+/Picasa. This is a sign of a disturbing trend away from the distributed web, where people and companies had their own web sites and got pagerank and subscribers, to the centralized AOL style model of one big site (be it Facebook or Google Plus) which is attractive because of its social synergies.
The video is very science-fictional, though they have built a concept to look at without the auto-driving. Amusingly, they do show something I have always thought would be a nice ironic demo — playing a car racing game while in a self-driving car. While we are some distance away form a car where the entire surface, inside and out, is a display, I do think we’ll see display panels on robocars to help them act as taxis. Those display panels will say who the taxi is for, and might even have your favourite bumper sticker slogan while you move inside. Inside displays will be useful for all the things you would expect — dashboard, work and entertainment.
Toyota is also showing a Prius with a system them call AVOS (Automatic Vehicle Operation System.) While this is said to be a longer-term self-driving systems, report suggest that what will be done at the motor show is back-seat rides demonstrating parking ability and pickup at the door, similar to Nissan’s Pivo and Stanford’s Junior 3, but with some added obstacle avoidance. I have not seen reports of rides as yet. The Prius itself is use more basic sensors than the Google car and other major robocars.
Nissan has announced a new version of their Pivo concept car. The Pivo 3 here’s a story with a video offers 4 wheel steering and automatic parking, including a claimed functionality for automated valet parking. In the AVP case, the car requires a special parking lot, though it is not said what changes are needed. A few years ago the Stanford team demonstrated Junior 3 which could valet park in a lot to which it had a map, and which had no civilian pedestrians.
The Pivo 3, it is reported, “will come and pick you up when you summon it.” Presumably this involves both the parking lot and the path to the door where you summon it containing the special infrastructure it needs, but this is not described. What’s also described is something fairly important — automatic charging, where the car takes itself to a charging station and hooks up.
They say they have no commercial plans for the car, but that they do expect to put such functionality into other cars around “2016 to 2017.”
With the Tokyo motor show about to start, expect new announcements from Japan in the days to come — for example Toyota has promised a self-driving Prius at the show, in a similar parking lot mode to the Pivo.
In contrast to the optimism I usually present here, and last week’s article about a self-driving Mercedes just a year away it’s worth noting this interview with various BMW folks where they provide a much more cautious timeline of at least a decade. Part of their concern comes from the use of computer vision systems. These are much cheaper than laser scanners but do not provide the reliability needed; it’s no accident that all the successful teams in the Darpa urban challenge relied very heavily on laser scanning.
I’m enough of an optimist that I am ready to bring forward the question “When will a child be born that never drives because of robocars?” Of course there are many people in the developed world who never get a licence for a variety of reasons, particularly people who live their lives in Manhattan and other transit-heavy cities. But for most of us, getting a licence and getting on the road is a rite of passage. Yet studies are showing that teens are now waiting longer to get a licence with various reasons speculated.
Nonetheless eventually we will see somebody who would normally have been jumping at the chance to get a licence and get out on the road who never gets one because they have a robocar. It won’t be easy of course, since even those who have robocars will still need to travel to places that don’t have them and rent cars, but many people who don’t have licences today just make use of taxis and transit in those situations.
I will put forward the proposal that this child may already have been born. When I see a baby today, I wonder, “will this child ever learn to drive?” While 16 years is aggressive for the ubiquitous fully autonomous operation needed for this, I do think we’re on the cusp, and if that child has not yet been born, it’s not too far away.
One reason for this is all the forces that are already reducing teen driving. A teen debating whether to take the effort to learn to drive might easily be swayed not to because mom has bought him a robocar. Once a successful safety record for robocars is demonstrated, parents will buy them for teens — instead of buying them driving lessons — and pressure the teens to not take the risk of driving themselves.
In other news, here’s a pointer to work by designer Charles Rattray on the look of future robocars. His designs match with my position that many robocars should be half the width of today’s cars, carrying only 1-2 people, since the vast majority of cars today only carry 1-2 people. Today’s car buyers insist on 5 passenger sedans (or larger) but when you have mobility-on-demand you can use the right vehicle for the trip on every trip, and that’s going to mostly be one person vehicles. This in turn, is the real key to efficient transportation, because while you can do great things with more efficient or electric power trains and more aerodynamic cars, nothing compares to making the car smaller, lighter and narrower in a major way. He has many design sketches and a video of how he sees the cars in action.
For the first time, a car company has put a date on shipment of a car with self-driving ability.
According to British site Auto Express, Mercedes has revealed that their 2013 S-class will feature self-driving. Not clear if there is an official company press release, though the company has been talking about such features, as have many other companies. Realize that the 2013 model year is just a year away.
The car will feature radar based automatic cruise control, combined with lane-marker following, and the automatic driving will only operate below 40kph. In other words, this is designed to let you take your hands off the wheel in stop-and-go traffic jams, not to drive you at actual open driving speeds. You’ll need to pay attention to the road, not read a book, but at that low speed you’ll have decent warning if something goes wrong and the car starts drifting, so I suspect that in spite of warnings not to do so, people will get away with minor tasks like reading a few e-mails or even sending some.
While a very basic level introduction, this is still a milestone and will pave the way (love those road metaphors) for other companies. While the focus of the DARPA grand challenges and most visions of the robocar future has been on cars that can drive completely on their own, there are now strong signals that the technology will arrive in the form of driving assist, and human drivers will be called upon to still do much of the driving, in particular the tricky bits the systems aren’t safe to handle. In my article a few years ago the roadmap to robocars I suspected we might see a few specialized applications first, such as robot valet parking and even autonomous vehicles for military delivery applications, but now the autopilot is on track for showing up commercially first.
I shoot with the Canon 5d Mark II. While officially not a pro camera, the reality is that a large fraction of professional photographers use this camera rather than the Eos-1D cameras which are faster but much bulkier and in some ways even inferior to the 5D. But it’s been out a long time now, and everybody is wondering when its successor will come and what features it will have.
Each increment in the DSLR world has been quite dramatic over the last decade. There’s always been a big increase in resolution with the new generation, but now at 22 megapixels there’s less call for that. While there are lenses that deliver more than 22 megapixels sharply, they are usually quite expensive, and while nobody would turn down 50mp for free, there just wouldn’t be nearly as much benefit from it than the last doubling. Here’s a look at features that might come, or at least be wished for.
More pixels may not be important, but everybody wants better pixels.
Low noise / higher ISO: The 5D2 astounded us with ISO 3200 shots that aren’t very noisy. Unlike megapixels, there is almost no limit to how high we would like ISO to go at low noise levels. Let’s hope we see 12,500 or more at low noise, plus even 50,000 noisy. Due to physics, smaller pixels have higher noise, so this is another reason not to increase the megapixel count.
3 colour: The value of full 3-colour samples at every pixel has been overstated in the past. The reason is that Bayer interpolation is actually quite good, and almost every photographer would rather have 18 million bayer pixels over 6 million full RGB pixels. It’s not even a contest. As we start maxing out our megapixels to match our lenses, this is one way to get more out of a picture. But if it means smaller pixels, it causes noise. The Foveon approach which stacked the 3 pixels would be OK here — finally. But I don’t expect this to be very likely.
Higher dynamic range: How about 16 bits per pixel, or even 24? HDR photography is cool but difficult. But nobody doesn’t want more range, if only for the ability to change exposure decisions after the fact and bring out those shadows or highlights. Automatic HDR in the camera would be nice but it’s no substitute for try high-range pixels.
Video & Audio
Due to the high quality video in the 5D2, many professional videographers now use it. Last week Canon announced new high-end video cameras aimed at that market, so they may not focus on improvements in this area. If they do, people might like to see things like 60 frame video, ability to focus while shooting, higher ISO, and 4K video. read more »
Last week, new studies came back on the California High Speed Rail project. They have raised the estimated cost to $99 billion, and dropped the ridership estimate to 36.8 million and $5.5 billion in annual revenue. Note that only around 20 million people currently fly the SF to LA corridor — they expect to not just capture most of those but large numbers of central valley trips.
Even at the earlier estimates the project was an obvious mistake, and there’s no way to financially justify spending $99 billion to pull in $5.3 billion/year even subbing zero in for the large operating cost. But for various political reasons involving getting federal money, some are still pushing for this project, and we may well build a short train to nowhere in the central valley just to get the federal bucks.
They’re planning there because the various cities in the populated areas have been fighting legal battles to block the train there, not wanting its disruption. Because the train can only stop if a very few places at the speed it wants to go, a lot of towns would end up having construction and noise and street blockage and not get a lot of use from the train.
The local opposition is a tough barrier, because the train ends up really only being useful where the people are. While I have doubts about how many people would ride the long haul, since few want to go from downtown SF to downtown LA, lots of people would ride a fast train in the urban areas. In particular, what nobody talks about is running the HSR primarily to the airport, and streamlining both security clearance and the connection with new technology. The only reason HSR is pushed as possibly competing with flights is because of the nightmare we have made of flying, where people have to get to airports 45 minutes ahead of even short-haul flights and take a fair bit of time to get out of airports on the other end and make it through traffic to their destinations. A fast train from a downtown to the airport where you clear security (and check bags) right on the train, and the train drops you right at the central gate areas post security would create an unbeatable trip from downtown anywhere to downtown anywhere.
For fast trains, the San Francisco to San Jose route is so short that a 250mph HSR could do the 48 mile trip between the towns in 12 minutes without stopping, call it 15 with the start and stop at each end. This opens up an interesting cost saving — you could build a single track, and have a train zip back and forth on it, and still provide service every 30 minutes. You could put a double-track section in the middle and have service every 15 minutes, with lots of safety interlocks of course. A single track requires less land, less of everything and could probably be built along easier routes, even highway medians in some cases. You could avoid turnaround time by having double track at the endpoints, so one train is leaving for opposite route the moment the other train arrives, giving each train quite a long turnaround — with double rolling stock.
Of course, having no stops is not that valuable because only a few people want to go from SJ to SF. People would want a stop at the airport as I have indicated, and at least one in Mountain View or Palo Alto. Each stop costs a bunch of time, and eventually the trip gets long enough that the single-track trick becomes less useful. For a while I’ve wondered if you could make trains that could dock, so that the main train runs non-stop and is able to shed cars which stop at local stops (not that hard) and to dock with cars coming from local stops (harder.) I proposed this 7 years ago near the start of this blog, and there are serious rail designers thinking along the same lines — see the video in that link.
In the Priestman Goode proposal, they have trains docking side to side. That seems much more challenging though it offers fast transfer. If you combine the two ideas, you would have two tracks — one for the nonstop trains and one for the docking shuttles which serve all the local stops. Indeed, if you could do this you could get rid of the old regular speed rail service running on existing track pairs because this would be superior in all ways except cost. My own proposals attempted to dock on a single track, which seems easier to me.
Robocars play a role in all this too. Even the HSR authority realizes they have a big problem, in that once people get quickly to an HSR station, they still have to get to their real destination. Using local transit may mean spending more time on a local bus than on the HSR. The mobility on demand of robocars is a great answer, and I’m pretty sure that with a 2030 forecast completion date (if they’re lucky) we’ll have robocars long before then. And the one thing cars can’t readily do is go very fast efficiently between cities.
The docking approach, should it work, has another advantage. The main train can take the best route (cheapest or shortest) without too much regard for where the stations are. People like stations in urban centers, but bringing the high speed train right through such areas (like Palo Alto) is hard and has caused the lawsuits. If the train goes through the industrial space along the Bay, and a spur goes into downtown for the shuttle that docks with it, you get a win all around.
Another approach that doesn’t require dock/undock works when you have a solid terminus like SF. You have 3 trains leave SF at the same time. The first one goes express to San Jose. The second goes express to Palo Alto and Mountain View and then switches to low speed tracks to go to Sunnyvale and Santa Clara. The third goes to SFO airport. Because SFO airport is also an origination point, it sends a train to SJ just before or after the one from SF, and another train to Mountain View right after that one. Mountain View to SJ service might be able to fit in or have to be local service. These sub-trains are just a few cars. This is not as energy efficient, though it can be if the trains are able to get close to one another and draft, sort of a virtual coupling without physical contact. You need perfect sync, and special long-spring collision bumpers in case the sync fails and they bump. The risk of higher-speed bumping must be prevented by failsafes that don’t even let the trains get on the same track until speed is matched close enough. This requires more than just a single track of course.
Congestion on the roads has a variety of sources. These include accidents of course, reductions in road capacity, irrational human driving behaviours and others, but most of all you get congestion when more cars are trying to use a road than it has capacity for.
That’s why the two main success stories in congestion today are metering lights and downtown congestion charging. Metering lights limit how fast cars can enter the highway, so that you don’t overload it and traffic flows smoothly. By waiting a bit at the metering light you get a fast ride once on the highway. Sometimes though, especially when the other factors like accidents come into play, things still gum up.
Now that more and more cars are connected (by virtue just of the smartphone the driver carries if nothing else) the potential will open up for something else in congestion — finding ways to encourage drivers to leave a congested road. read more »
A little self-plug. I have an article on an introduction to panoramic photographic technique the November issue of Photo Technique with a few panos in it. This is old world journalism, folks — you have to read it on paper at least for now.
We decided to go to Harvey’s pan in Savuti one afternoon and lucked upon a large breeding group of elephant just on their way there. I caught them in one of my first long lens panoramas. Long lens panos are fairly difficult due to the limited depth of field, but they get great detail on the baby elephant.
I’m just back from the “ITS World Congress” an annual meeting of people working on “Intelligent Transportation Systems” which means all sorts of applications of computers and networking to transportation, particularly cars. A whole bunch of stuff gets covered there, including traffic monitoring and management, toll collection, transit operations etc. but what’s of interest to robocar enthusiasts is what goes into cars and streets. People started networking cars with systems like OnStar, now known in the generic sense as “telematics” but things have grown since then.
The big effort involves putting digital radios into cars. The radio system, known by names like 802.11p, WAVE and DSRC involves an 802.11 derived protocol in a new dedicated band at 5.9ghz. The goal is a protocol suitable for safety applications, with super-fast connections and reliable data. Once the radios in the car, the car will be able to use it to talk to other cars (known as V2V) or to infrastructure facilities such as traffic lights (known as V2I.) The initial planned figured that the V2I services would give you internet in your car, but the reality is that 4G cellular networks have taken over that part of the value chain.
Coming up with value for V2V is a tricky proposition. Since you can only talk to cars very close to you, it’s not a reliable way to talk with any particular car. Relaying through the wide area network is best for that unless you need lots of bandwidth or really low latency. There’s not much that needs lots of bandwidth, but safety applications do demand both low latency and a robust system that doesn’t depend on infrastructure.
The current approach to safety applications is to have equipped cars transmit status information. Formerly called a “here I am” this is a broadcast of location, direction, speed and signals like brake lights, turn signals etc. If somebody else’s car is transmitting that, your car can detect their presence, even if you can’t see them. This lets your car detect and warn about things like:
The car 2 or 3 in front of you, hidden by the truck in front of you, that has hit the brakes or stalled
People in your blind spot, or who are coming up on you really fast when your’re about to change lanes
Hidden cars coming up when you want to turn left, or want to pass on a rural highway
Cars about to run red lights or blow stop signs at an intersection you’re about to go through
Privacy is a big issue. The boxes change their ID every minute so you can’t track a car over a long distance unless you can follow it over every segment, but is that enough? They say a law is needed so the police don’t use the speed broadcast to ticket you, but will it stay that way?
It turns out that intersection collisions are a large fraction of crashes, so there’s a big win there, if you can do it. The problem is one of critical mass. Installed in just a few cars, such a system is extremely unlikely to provide aid. For things like blindspot detection, existing systems that use cameras or radars are far better because they see all cars, not just those with radios. Even with 10% penetration, there’s only a 1% chance any given collision could be prevented with the system, though it’s a 10% chance for the people who seek out the system. (Sadly, those who seek out fancy safety systems are probably less likely to be the ones blowing through red lights, and indeed another feature of the system — getting data from traffic lights — already can do a lot to stop an equipped car from going through a red light by mistake.) read more »
