Ok, this is a silly idea, but it would make a great baby shower gift. Crib sheets — which is to say sheets to go on a baby’s bed — printed with small notes on your favourite subjects of choice — math, physics, history, as you would need for taking an exam. And who knows, maybe you can pretend if the baby sleeps surrounded by Maxwell’s equations she’ll become a genius.
I’m not a gamer. I wrote video games 25 years ago but stopped when game creation became more about sizzle (graphics) than steak (strategy.) But the story of the release of the Playstation 3 is a fascinating one. Sony couldn’t make enough, so to get them, people camped out in front of stores, or in some cases camped out just to get a certificate saying they could buy one when they arrived. But word got out that people would pay a lot for them on eBay. The units cost about $600, depending on what model you got, but people were bidding thousands of dollars even in advance, for those who had received certificates from stores.
It was amusing to read the coverage of the launch at Sony’s own Sonystyle store in San Francisco. There the press got bored as they asked people in line why they were lining up to get a PS3. The answer most commonly seemed to be not a love of gaming, but to flip the box for a profit.
And flip they did. There were several tens of thousands of eBay auctions for PS3s, and prices were astounding. About 20,000 auctions closed. Another 25,000 are still running at this time. Some auctions concluded for ridiculous numbers like $110,000 for 4 of them, or a more “reasonable” $20,000 for 5. Single auctions reached as high as $25,000, though in many of these cases, it’s bad news for the seller because the high bidders are people with zero eBay reputation who obviously won’t complete the transaction. In other cases serious sellers will try to claim their bid was a typo. There are some auctions with serious multiple bidders that got to 3 and 4 thousand dollars, but by mid-day today they were all running about $2,000, and they started dropping very quickly. As I watched in a few minutes they fell from $1,500 to going below a thousand. Still plenty of profit for those willing to brave the lines.
It’s interesting to consider what the best strategy for a seller is. It’s hard to predict what form a frenzy like this will take, and when the best price will come. The problem is eBay has a minimum 1 day for the auction, so you must guess the peak 1 day in advance. Since many buyers were keen to see the auction listing showing that the person had the unit in hand, ready to ship, the possible strategy of listing the item before going to get it bore some risks. Some showed scans of their pre-purchase.
The most successful sellers were probably those who picked a clever “buy it now” price which was taken during the early frenzy by people who did not realize how much the price would drop. All the highest auctions (including those with fake buyers) were buy-it-now results. Of course, it’s mostly luck in guessing what the right price was. I presume the buy-it-now/best-offer feature (new on eBay) might have done well for some sellers.
However, those who got a bogus buyer are punished heavily. They can re-list, but must wait a day to sell by auction, and will have lost a bunch of money in that day. If they can find the buyer they might be able to sue. If they are smart, they would re-list with a near-market buy-it-now to catch the market while it’s hot.
Real losers are those who placed a reserve on their auctions, or a high starting bid price. In many cases their auctions will close with no succesful bidder, and they’ll sell for less later. Using a reserve or high starting bid makes no sense when you have such a high-demand item. Those paranoid about losing money should have at most started bidding at their purchase price. I can’t think of any reason for a reserve price auction in this case — or in most other cases, for that matter. Other than with experimental rare products, they are just annoying.
Particularly sad was one auction where the seller claimed to be a struggling single mom who had kids that lucked out and got spots in line, along with pictures of the kids holding the boxes. She set a too-high starting price, and will have to re-list.
Another bad strategy was to do a long multi-day listing.
It’s possible the rarity of these items will grow, as people discover they just can’t get one for their kids for Christmas, but I doubt it.
The other big question this raises is this: Could Sony have released the machine differently? Sony obviously left millions on the table here, about 30 to 40 million I would guess. That’s tolerable for Sony, and they might have decided to give it up for the publicity that surrounds a buying craze. But I have to wonder, would they not have been better served to conduct their own auctions, perhaps a giant dutch auction, for the units, with some allocated at list price by lottery or for those willing to wait in line so that it doesn’t seem so elitist. (As if any poor person is going to buy a PS3 and keep it if they can make a fast thousand in any event.)
Some retailers took advantage of demand by requiring customers to buy several games with the box, presumably Sony approved that. With no control from Sony all the retailers would be trying to capture all this money themselves, which they could easily have done — selling on eBay directly if need be.
I predict in the future we will see a hot Christmas item sold through something like a dutch auction, since being the first to do that would generate a lot of publicity. Dutch auctions are otherwise not nearly so exciting. When Google went public through one, the enemies of dutch auctions worked to make sure people thought it was boring, causing Google to leave quite a bit of money on the table, but far less than they would have left had they used traditional underwriters.
On a side note — if you shop on eBay, I recommend the mozilla/firefox/iceweasel plugin “Shortship” which fixes one of eBay’s most annoying bugs. It lets you see the total of price plus shipping, and sort by it, at least within one ebay display page.
Differential pricing occurs when a company attempts to charge different prices to two different customers for what is essentially the same product. One place we all encounter it a lot is air travel, where it seems no two passengers paid the same price for their tickets on any given flight. You also see it in things like one of my phones, which has 4 line buttons but only 2 work — I must pay $30 for a code to enable the other 2 buttons.
The public tends to hate differential pricing, though in truth we should only hate it when it makes us pay more. Clearly some of the time we’re paying less than we might pay if differential pricing were not possible or illegal.
So even if differential pricing is neutral, one can rail if it punishes/overcharges the wrong thing. There might be a better way to get at the vendor’s goal of charging each customer the most they will tolerate — hopefully subject to competition. Competition makes differential pricing complex, as it’s only stable if all competitors use roughly the same strategy.
In air travel, the prevailing wisdom has been that business travellers will tolerate higher ticket prices than vacation travellers, and so most of the very complex pricing rules in that field are based on that philosophy. Business travellers don’t want to stay over weekends, they like to change their flights, they want to fly a combination of one-way trips and they want to book flights at short notice. (They also like to fly business class.) All these things cost a lot more in the current regime.
Because of this, almost all the travel industry has put a giant surcharge on flexibility. It makes sense that it might cost a bit more — it’s much easier to schedule your airline or hotel if people will book well in advance and keep to their booking — but it seems as though the surcharge has gotten immense, where flexible travel can cost 2 to 4 times what rigidly scheduled travel costs. Missing the last flight of the day can be wallet-breaking. Indeed, there are many arguments that since an empty seat or hotel room is largely wasted, vendors might be encouraged to provide cheaper tickets to those coming in at the last minute, rather than the most expensive. (And sometimes they do. In the old days flying standby was the cheapest way to fly, suitable only for students or the poor. There are vendors that sell cheap last minute trips.)
Vendors have shied away from selling cheap last-minute travel because they don’t want customers to find it reliable enough to depend on. But otherwise it makes a lot of sense.
So my “Solve this” problem is to come up with schemes that still charge people as much as they will tolerate, but don’t punish travel flexiblity as much.
One idea is to come up with negative features for cheap tickets that flexible, non-business travellers will tolerate but serious business travellers and wealthy travellers will not. For example, tickets might come with a significant (perhaps 10-20%) chance of being bumped, ideally with sufficient advance notice by cell phone that you don’t waste time going to the airport. For example, the airline might sell a cheap ticket but effectively treat the seat as available for sale again to a higher-paying passenger if they should come along. You might learn the morning of your trip that somebody else bought your seat, and that you’ll be going on a different flight or even the next day. They would put a cap on how much they could delay you, and that cap might change the price of your ticket.
For a person with a flexible work schedule (like a consultant) or the retired, they might well not care much about exactly what day they get back home. They might like the option to visit a place until they feel like returning, with the ability to get a ticket then, but the risk that it might not be possible for a day or two more. Few business travellers would buy such a ticket.
Such tickets would be of most value to those with flexible accomodations, who are staying with friends and family, for example, or in flexible hotels. Rental cars tend to be fairly flexible.
Of course, if you’re willing to be bumped right at the airport, that should given you an even cheaper ticket, but that’s quite a burden. And with today’s ubiquitous cell phones and computer systems there’s little reason not to inform people well in advance.
This technique could even provide cheaper first-class. You might buy a ticket at a lower price, a bit above coach, that gets you a first class seat half the time but half the time puts you in coach because somebody willing to pay the real price of first class bought a ticket. (To some extent, the upgrade system, where upgrades are released at boarding time based on how many showed up for first class, does something like this.)
Any other ideas how airlines could provide cheaper flexible tickets without eating into their business flyer market? If only one airline tries a new idea, you get an interesting pattern where everybody who likes the new fare rules switches over to that airline in the competitive market, and the idea is forced to spread.
Added note: In order to maintain most of their differential pricing schemes today, airlines need and want the photo-ID requirement for flying. If tickets (including tickets to half a return trip) could be easily resold on the web to anybody, they could not use the systems they currently use. However, the system I suggest, which requires the passenger be willing to be bumped, inhibits resale without requiring any type of ID. A business traveller might well buy a cheap ticket at the last minute from somebody who bought earlier, but they are going to be less willing to buy a ticket with unacceptable delay risks associated with it.
I’ve written before about one of the greatest flaws in the modern political system is the immense need of candidates to raise money (largely for TV ads) which makes them beholden to contributors, combined with the enhanced ability incumbents have at raising that money. Talk to any member of congress and they will tell you they start work raising money the day after the election.
Last year I proposed one radical idea, a special legitimizing of political spam done through the elections office. That will take some time as it requires a governmental change. So other factors are coming forward.
In some states and nations, efforts are already underway to have the government finance elections. The Presidential campaign fund that you contribute to whether you check the box on the tax return or not is one effort in this direction.
I propose that the operators of the big, advertising-supported web sites, in particular sites like Yahoo, Google, Microsoft, Myspace and the like join together to create a program to give free web advertising to registered candidates on a fair basis. This could be done by simply providing unsold inventory, which is close to free, or it could be real valuable inventory including credits for targetted ads.
Of course, not everybody reads the web all day, so this only reaches one segment of the population, but it reaches a lot. The main goal is to reduce the need, in the minds of candidates, to raise a lot of money for TV ads. They won’t stop entirey, but it might get scaled back.
Such a system would allow users the option of setting a cookie to provide preferences for the political ads they see. While each candidate would get one free shot, voters could opt-out of ads for specific candidates or races. (In some cases the geography-matcher would get it wrong and they would change the district the system think they are in.) They could also tone down the amount of advertising, or opt in or out of certain styles (flash, animated, text, video.)
It would be up to candidates to tune their message, and not overdo things or annoy voters, pushing them to opt out.
There can’t be too much opting out though, because the goal here is to deliver the same thing that candidates rely on TV for — pushing their message at voters who have not gone seeking it. If we don’t provide that, we’ll never cut the dependency on TV and other intrusive ads. Allowing these ads to be intrusive seems wrong, but the real thing to do is consider the competition, and what its thirst for money does to society. Thanks to the internet, we’ve reduced the price of advertising by an order of magnitude. If the price of advertising is what corrupts the political system, it seems we should have a shot of fixing the problem.
Ads would be served by the special consortium managing the opt-out system, not the candidate, in order to protect privacy. So if you click on an ad for a candidate, the first landing page is not hosted by the candidate, but may have links to their site.
A system would have to be devised to allocate “importance” to elections. Ie. how many ads do the candidates for President get vs. those for state comptroller.
One risk is that the IRS or other forces might try to declare this program a political contribution by the web sites. If applied fairly to all candidates, we’ll need a ruling that states it is not a contribution. This is needed, because otherwise sites will balk at the idea of running free ads for candidates they dispise.
If the system got powerful enough, it could even make a bolder claim. It could only allow the free advertising to candidates who agree to spending limits in other media. On one hand this is just what most campaign finance reform programs do to avoid the 1st amendment. On the other hand, it may seem like an antitrust violation — deliberately giving stuff away not just to kill the “competition” but actually forbidding the candidates from spending too much with the competition.
This need not be limited to the web of course. Other media could join in, though the ones that already make a ton of money from political advertising (TV, radio) are not so likely to join.
This won’t solve the whole problem, but it could make a dent, and even a dent is pretty important in a problem as major as this.
I go to many conferences, and most of them seem to want to give me a nice canvas bag, and often a shirt as well. Truth is though, I now have a stack of about 20 bags in my closet. I’ve used some of the bags, typically the backpacks, but when I have so many other bags I don’t feel a strong motivation to walk around with a briefcase or laptop bag with a giant sponsor’s logo on it, or worse, a collection of 10 logos. No matter how nice the bag is. In addition, even if I got logo-free bags I have no need for 20 of them, but I can’t really give away logo covered bags as gifts.
Which means the sponsor wasted their money. And I think this is common, for while I sometimes see people carrying a sponsor bag outside the confines of a conference, it’s pretty rare compared to the number given out. You want me to be your billboard, I want more than a bag for it.
Might some sponsors take the plunge and make a bag with the sponsor’s logo inside the bag? Or perhaps if on the outside, in a more subtle way. This seems stupid at first, but a bag I actually use, which at least reminds me of the company when I use it, is better than a bag that stays stacked in a closet. (Of course, logo-inside bags would be given away more, which may not accomplish much.) Perhaps the sponsors should go in for designer bags, and turn their logos into desirable designer logos?
If your name is Versace, you can get people to pay to carry your advertising, but sorry, not if your name is AT&T. I hope you can get over it. And while a bag is useful for carrying stuff home from the conferences and even storing literature, truth is you can use a $1 bag for that, not a $15 one. We really have to hunt to find better conference giveaways than bags, at least at conferences whose attendees all attend other fancy conferences.
It does get hard to be a privacy advocate when it’s easy to think of interesting apps that make use of tracking infrastructure. Here’s one.
How often have you wanted to talk to somebody in a car next to you on the road? Consider a system where people could register their licence plate(s) with their cell phone account. Then, if they had done this, you could call a special number on your own cell phone, and enter the numeric part of their licence plate.
If both you, and the other car were close by (for example in the same cell, but often the cell companies have much closer tracking information) and both of you were moving, it could then complete the call to the other car. The other car might get to screen the call (ie. you would have to enter the reason for the call and they would hear, “Will you accept a call from
Sounds like a good product for the cell companies, able to generate minutes. Easy enough to do if both people use the same cell company, lots more work between two different companies where a protocol would be needed. Would be easier to do with texting but you don’t want people texting in cars.
Could have used it last night, was tailing a friend on the road to her house, did not have her cell number but could see her plate.
As I’ve described the system it’s opt-in, nobody calls you unless you sign up for it and register a plate. However it could be made fairly safe to opt-in with a number of protections. As noted, the system could demand the cars are moving (cell network can see that) so that it can’t be used to reach your cell phone while you are not driving. You could have screening.
It should also have a reputation system. For example, if you call me, then after we disconnect I can leave a negative reputation comment on you. Get a few of these and you’re out of the system. This assures people don’t use it simply to express road rage at the next driver or other things that are largely annoying. On the other hand you can use it to tell people their blinker is blinking or their trunk is open. (Mind you, once you are aware of a problem you would want a function to tell callers you are aware of a driving problem and to press 2 if they are calling about something else.)
And sure, for those open to it, it would be used for flirting with the cutie who gave you the eye when you were both stopped at the light.
You can of course just stick your cell number on your bumper to do this, but it would not have the opt-out and reptuation systems. With today’s cheap phone numbers, however, you could get a special number that forwards to your cell and performs the screening/reputation/etc. but is not able to use the location awareness.
If the digits are not unambiguous (or, like me, you have a custom plate that’s all letters) the system would need to offer you the cars close to you that match.
This weekend I experienced an air travel policy that I had not seen before and which I found quite shocking. I was flying on United Express (Skywest)’s flight from San Francisco to Calgary. As we waited for the early morning flight, they announced this “weather warn.” Visibility was poor in Calgary due to low clouds. Below 0.5 miles they plane would not be allowed to land there. They rated about a 1/3rd chance of this happening, 2/3 chance we would land normally.
The catch was this, if, when they got to Calgary, they found they could not land, they would divert to Great Falls, MT. After dropping the passengers in Great Falls, we would be entirely on our own, with no assistance at all with getting to Calgary via ground or air. (United Express and a few other airlines do sell tickets from Great Falls to Calgary, though all via fairly distant hubs like Denver, Salt Lake etc.) The important point about this is that the diversion is to an airport in a different country from the intended destination. This makes ground transportation particularly difficult, as car rental companies are disinclined to offer economical one-way rentals between countries — not to mention the 6 hour drive. (Hertz will do it for about $320/day.)
I just checked and Greyhound will get you there in 1 day, 14 hours via Seattle and Vancouver. Amtrak doesn’t even go there.
Now the other passengers who had seen this before said that it usually works out, so we got on with a sense of adventure. But it would have been a big adventure had we been diverted, and just seemed to be a rather strange state for the airline to leave passengers. Yes, they did say that if we elected not to get on the flight, we could try a later one (with no assurance there would not be the same weather warning on that flight.) Most of the passengers got on, and we did land OK, but a few backed out.
Some international bureaucracy, they said, forbids them from landing at another Canadian airport, such as obvious choices like Edmonton, or even various smaller airports since this was a Canadair regional jet able to land at small airports. But just about anything would have been superior to Great Falls in the USA — some city with a means of getting to the destination. Indeed, the plane after landing in either GF or Calgary would have headed on to Chicago, which while far away, is at least a city one could find a flight to Calgary from, and from which United could certainly have arranged travel for the passengers.
I’m taking a wild guess that this bureaucracy is 9/11 related, but I could be wrong. But if it is, it’s another secret burden of that day.
(The likely result — passengers would probably have formed up in groups of 5 to rent Hertz cars and drive to Calgary. The cost — $320 plus $50 of gas — would have been tolerable shared among 5 people who would know one another much better by the end of the day. Of course we didn’t know this when making the decision.) There are also some slight cheaper but inconvenient tricks involving an in-Montana rental which drives to an Alberta town near the border, where one of the passengers rents a car there, and both cars drive to a Montana drop-off and then the Alberta car continues to Calgary. You would need a sense of adventure to do that.
I'm in Edmonton. Turns out to be the farthest north I've been on land (53 degrees 37 minutes at the peak) after another turn through the Icefields Parkway, surely one of the most scenic drives on the planet. My 4th time along it, though this time it was a whiteout. Speaking tomorrow at the CIPS ICE conference on privacy, nanotechnology and the future at 10:15.
Idea of the day. I joined Fairmont Hotels President's Club while at the Chateau Lake Louise because it gave me free internet. When I got to the Fairmont Jasper Lodge my laptop just worked with no login, and I was really impressed -- I figured they had recorded my MAC address as belonging to a member of their club, and were going to let me use it with no login. Alas, no, the Jasper lodge internet (only in main lobby) was free for all. But wouldn't that be great if all hotels did that? Do any of the paid wireless roaming networks do this? (I guess they might be afraid of MAC cloning.) It would also allow, with a simple interface, a way for devices like Wifi SIP phones to use networks that otherwise require a login.
Of course, as we all know, the more expensive the hotel, the more likely the internet is not only not included, it's way overpriced. At least Fairmont gave one way around this. Of course I gave them a unique E-mail address created just for them, so if they spam me I can quickly disable them. But once again I, like most of us, find myself giving up privacy for a few hotel perks.
When I’m having a problem with a company, I try sometimes to remind them of a principle of customer service I worked out when I was running ClariNet. Namely that when a company screws up, it should more than fix the problem, even to the point of losing money (for a while) on that customer. The reason, in brief, is that this does more than make the customer happy with the transaction. It signals in the strongest possible way that the screw-up is a rare event, which makes the customer come back for more.
I have outlined it in this page on Brad’s principle of customer service.
You’ve seen the flap recently because a student, to demonstrate the fairly well discussed airport security flaw involving the ease forgeability of boarding passes, created a web site where you could easily create a fake Northwest boarding pass. Congressman Markey even called for the student’s arrest, then apologized, but in the meantime the FBI raided his house and took his stuff.
As noted, this flaw has been discussed for some time. I certainly saw it the first time I was able to print my own boarding pass. However, it’s not really limited to print-at-home boarding passes, and it’s a shame the likely reaction to this will be to disable that highly convenient service. Airline issued boarding passes are just thicker paper. I don’t see it being particularly difficult with modern colour printers — which are able to pull off passable money given the right paper — to produce good airline printed boarding passes.
It’s possible the reaction to this will be to simpy add a gate ID check for people with home printed boarding passes, which will at least retain those passes without slowing down the boarding process even more, but it doesn’t actually fix the problem.
The current system of easy to forge boarding passes, combined with ID check at TSA security and boarding pass check at the gate, has the following flaws:
- You can, as noted, fly if you are on the no-fly list with no problems. If I were named David Nelson I would consider it.
- You can bypass the selectee system, where they print SSSS on your boarding pass to mark you for “full service” searching. (I’ve been told an additional stamp is placed on your boarding pass after the search, you need to forge this too.)
- You can transfer your ticket to another person without telling the airline or paying them. You also earn flyer miles even though somebody else got on the plane
- It allows people to enter the gate area who aren’t actually flying. This is not a big security risk, but it slows down the security line. You don’t want to miss your flight because people slowed down the line to meet their friends at the gate.
Some airports have the TSA ID-checker put a a stamp on the boarding pass. However, this is also not particularly difficult to forge. Just have somebody go through once to get today’s stamp, have them come back out and now you can forge it.
The simplest answer is to have ID check at the gate. This slows boarding, however, which is bad enough as it is. The hard answer is to have unforgeable boarding passes or an unforgeable stamp or non-removable sticker at TSA.
Probably the best solution is that the TSA station be equipped with an electronic boarding pass reader which can read the barcodes on all types of boarding passes, which themselves must be cryptographically secure. Then the name printed on the pass becomes unimportant, except so you can tell yours from your companion’s. The scanner would scan the pass, and display the name of the passenger on the screen, which could then be compared to the ID.
Sadly, I fear this suggestion would go further, and the full panopticon-enabled system would display the photo of the passenger on the screen — no need to show your ID at all.
Though mind you, if we didn’t have the no-fly-list concept, one could actually develop a more privacy enhancing system with photos. When you bought your ticket, if you didn’t care about FF miles, you would provide a photo of the passenger, not their name or anything else about them. The photo would be tied to the boarding record. To go through security or board the aircraft, you would present the boarding pass number or bar-code, and TSA, gate and luggage check agents would see your photo, and pass you through. The photo confirms that the person pictured has a valid ticket. This meets most of the goals of the current system, except for these:
- It doesn’t allow a no-fly-list. But the no-fly-list is bad security. Only random screening is good security
- It doesn’t allow gathering marketing data on passengers. But the frequent flyer system does.
- It doesn’t allow the airline to generate a list of dead passengers in the event of a crash.
As noted, the marketing data goal is met by the FF program. It would be possible, by the way to build a fairly private FF program where you don’t give your name or address for the program. You just create an FF account online, and get a password, and you can place a picture in it and associate it with flights. You can then redeem flights from it, all online. But I doubt the airlines will rush to do this, they love selling data about you.
The dead-passenger problem can be solved to some degree. They would have, after all, pictures of all the passengers so they could be identified by people who know them. In a pinch, identity could also be escrowed, with the escrow agency requiring proof of the death of the passenger before revealing their identity. That’s pretty complex.
There’s no good way to solve the no-fly-list problem unless you have credible face recognition software. Even that wouldn’t work because it’s not hard to modify a photo to screw up what the face recognition software is looking for but still have it look like you. But frankly the no-fly-list is bad security and it’s not a bug that it doesn’t work in this system.
As I wrote before, I want power plugs and jacks to be smart, so they can negotiate how much power the device needs and how much the supply can provide, and then deliver it.
However, sometimes, what the supply can provide changes. The most obvious example is a grid power failure. It would not be hard, in the event of a grid power failure, to have a smaller, low capacity backup system in place, possibly just from batteries. In the event of failure of the main power, the backup system would send messages to indicate just how much power it can deliver. Heavy power devices would just shut off, but might ask for a few milliwatts to maintain internal state. (Ie. your microwave oven clock would not need an internal battery to retain the time of day and its memory.) Lower power devices might be given their full power, or they might even offer a set of power modes they could switch to, and the main supply could decide how much power to give to each device.
Of course, devices not speaking this protocol, would just shut off. But things like emergency lights need not be their own system — though there are reasons from still having that in a number of cases, since one emergency might involve the power system being destroyed. However, battery backup units could easily be distributed around a building.
In effect, one could have a master UPS, for example, that keeps your clocks, small DC devices and even computers running in a power failure, but shuts down ovens and incandescent bulbs and the like, or puts devices into power-saving modes.
We could go much further than this, and consider a real-time power availability negotiation, when we have a power supply or a wire with a current limit. For example, a device might normally draw 100mw, but want to burst to 5w on occasion. If it has absolutely zero control over the bursts, we may have to give it a full 5w power supply at all times. However, it might be able to control the burst, and ask the power source if it can please have 5w. The source could then accept that and provide the power, or perhaps indicate the power may be available later. The source might even ask other devices if they could briefly reduce their own power usage to provide capacity to the bursting device.
For example, a computer that only uses a lot of power when it’s in heavy CPU utilization might well be convinced to briefly pause a high-intensity non-interactive task to free up power for something else. In return, it could ask for more power when it needs it. A clothes-dryer or oven our furnace or other such items could readily take short pauses in their high power drain activities — anything that uses a cycle rather than 100% on can do this.
This is also useful for items with motors. A classic problem in electrical design is that things like motors and incandescent lightbulbs draw a real spike of high current when they first turn on. This requires fuses and circuit breakers to be “slow blow” because the current is often briefly more than the circuit should sustain. Smart devices could arrange to “load balance” their peaks. You would know that the air conditioner compressor would simply never start at the same time as the fridge or a light bulb, resulting in safer circuits even though they have lower ratings. Not that overprovisioning for safety is necessarily a bad thing.
This also would be useful in alternative energy, where the amount of power available changes during the day.
Of course, this also applies to when the price of power changes during the day, which is one application we already see in the world. Many power buyers have time-based pricing of their power, and have timers to move when they use the power. In many cases whole companies agree their power can be cut off during brown-outs in order to get a cheaper price when it’s on. With smart power and real-time management, this could happen on a device by device basis.
These ideas also make sense in power over ethernet (which is rapidly dropping in price) which is one of the 1st generation smart power technologies. There the amount of power you can draw over the thin wires is very low, and management like this can make sense.
In the 90s, when I had more money, I did some angel investing. One of the companies I invested in, Sierra Sciences was started by an old friend and business associate, Dan Fylstra, who had also founded Personal Software/VisiCorp, the company that sold VisiCalc.
Sierra Sciences was also founded by Bill Andrews, who had done important work on Telomeres at Geron. Together, we hoped to follow promising leads on now to safely lengthen the telomere.
Telomeres are strands on the end of chromosomes. Each time a chromosome is duplicated, they shorten, acting like a decremating “counter.” After so many duplications (50 to 60) the telomere is too short and the cell can’t divide. That gives a fresh gamete 2^50 cells to produce, which is a ton, but of course we are the result of highly specialized duplication so it turns out to not be enough. Telomeres are in part a defence against cancer. If a cancer forms, and starts duplicatating like crazy, it hits the limit of the telomere and stops — unless it has found a way to generate Telomerase, the enzyme that resets the counter. We need that enzyme in order to make babies, and certain types of immune cells and IIRC marrow, but in most of our cells it is repressed, in order to stop cancer.
They’ve known how to turn on telomerase and make immortal cell lines for a while, but this would increase the risk of cancer. The trick is to lengthen them just a bit. This would, in theory, give you some of the healing ability of a baby. Old people’s skin wounds heal very slowly because their cells are all divided out — they can’t produce endless new cells quickly.
A study a few years ago showed that people with naturally longer telomeres (just a bit longer) live about 4 years longer on average than those with shorter ones. That’s a big difference, and we hoped even a larger effect could be generated. We identified the sites that repress telomerase and found antagonists for the chemicals binding those sites.
But, after several years and a lot of money, have not yet found a drug to make the magic happen. The major investors have decided not to go forward. The company is for sale. While the investors won’t make much, if anything from it, I hope it is bought not just for the lab equipment but by somebody interested in carrying on the research. Most of the investors not only knew that anti-aging drugs would be very lucrative, they sort of hoped to be on the customer list someday.
It generated some interesting issues. Getting approval for such drugs would be a hard slog. It was debated that an animal drug be developed, as people would pay a lot for longer lived pets and racehorses. I was scared of this, knowing that humans would take the animal drug in desperation — with possible scary results due to lack of testing and refinement. The other hope was for a topical skin cream that really made skin be younger, not just look younger. This would be medically valuable and of course sell a lot for cosmetic applications. But it’s not to be for now.

In thinking about how to reduce the cost of bringing fiber to everybody (particulaly for block-area-networks built by neighbours) I have started wondering if we could build a robot that is able to traverse utility poles by crawling along wires — either power, phone or cable-TV wires. The robot would unspool fiber optic cable behind it and deploy wire-ties to keep it attached. Human beings would still have to eventually climb the poles and install taps or junctions and secure these items, but their job would be much easier.
Robots that can crawl along cables already exist. The hard part is traversing the poles. Now it turns out finding live electric wires is something that’s very easy for a robot to do. They stick out like a live wire in the EM spectrum. The poles of course have insulators, junctions, tie downs and other obstacles. Crossing them may be hard in certain cases (in which case a human would have to help, either by tele-operation, or by climbing the pole.) It may be possible to have a very small robot that is able to follow the current (easy to tell the lines to the houses from the main lines) and cross a pole like a bug and then, once safely on the other side, pulls the larger robot with a small tether. Again, it won’t always work but if you can get it to work enough of the time, you can install fiber with far less time and labour than the manual approach. Fiber of course can be tied to power lies because it is non-conductive material, though it’s even better if you can run it along phone or cable lines.
Not that any of these companies will want to give permission to competitors. And you want to pull multiple fibers, not so much for the bandwidth — we can do terabits in a single fiber if we want to — but for the backup when one fiber breaks.
If the robots get good enough, they could even string fiber into rural areas, following long chains of power or phone lines with just a single human assistant. Of course overhead wires are going to be more prone to breakage, but with these robots, repairs could be fast and cheap.
There are already robots out there which can crawl storm sewers to install fiber. This is another alternative, though that’s good too. Indeed, a robot that can even crawl real sewage lines to put in fiber which comes out your household stack is not out of the question, if it’s in a strong enough casing.
Over 15 years ago I proposed that USENET support the concept of “replacing” an article (which would mean updating it in place, so people who had already read it would not see it again) in addition to superseding an article, which presented the article as new to those who read it before, but not in both versions to those who hadn’t. Never did get that into the standard, but now it’s time to beg for it in USENET’s successor, RSS and cousins.
I’m tired of the fact that my blog reader offers only two choices — see no updates to articles, or see the articles as new when they are updated. Often the updates are trivial — even things like fixing typos — and I should not see them again. Sometimes they are serious additions or even corrections, and people who read the old one should see them.
Because feed readers aren’t smart about this, it not only means annoying minor updates, but also people are hesitant to make minor corrections because they don’t want to make everybody see the article again.
Clearly, we need a checkbox in updates to say if the update is minor or major. More than a checkbox, the composition software should be able to look at the update, and guess a good default. If you add a whole paragraph, it’s major. If you change the spelling of a word, it’s minor. In addition to providing a good guess for the author, it can also store in the RSS feed a tag attempting to quantify the change in terms of how many words were changed. This way feed readers can be told, “Show me only if the author manually marked the change as major, or if it’s more than 20 words” or whatever the user likes.
Wikis have had the idea of a minor change checkbox for a while, it’s time for blogs to have it too.
Of course, perhaps better would be a specific type of update or new post that preserves thread structure, so that a post with an update is a child of a parent. Which means it is seen with the parent by those who have not yet seen the parent, but as an update on its on for those who did see it. For those who skipped the parent (if we know they skipped) the update also need not be shown.
I recently read how airline cabins are getting more and more grotty of late. This is due to having fewer cleaning staff on hand, shorter turnaround times for cleaning, and passengers now bringing aboard more of their own food. This got me thinking on how we might improve the airline seatback.
First of all, to help keep things cleaner, it would be nice if we could divide the stuff the airline puts into the pocket from our own stuff. I would like the airline to put in less stuff — we really don’t need a skymall and inflight magazine at every seat, those can be fetched like the other magazines. The safety card, airsick bag and headpones (if present) could be put in a small plastic pouch that goes in the seat pocket, making it clear what’s yours and what’s the airlines. This makes it easier for you to clean out your stuff, including garbage, or for the airline cleaning crews to identify what’s permanent in the pocket and quickly toss the rest.
But there are some more dramatic improvements we could make here. Many years ago, I adapted one of those book holding stands meant for tables with a book light and velcro straps to hang it on the seat in front of me. (Back then velcro on the seat top was common.) This allowed me to hang my book on the seat in front of me, which I found made for much more comfortable reading. I find reading paperbacks on the plane requires contortion to get the book in good light, or simple arm-tiring labour to hold the book up. My back of seat mount was great, and the airlines could either provide those, or provide a “mounting point” into which a passenger-brought unit could be mounted. The mounting point could be where the tray locks, or on the back of the tray.
The mounting point also could be useful for the design of special laptop holders. Using a laptop in narrow-pitch coach seats is a pain, and a serious pain if the person in front of you wants to recline. In some cases you can’t use your computer unless you recline too. Some laptops are better designed for this, moving their screen hinge inward, at the cost of reducing wrist rest space.
For many people, airline use is one of the most important functions of their laptop, so a little special equipment or redesign could make some sense. In this case, a mounting point on the seat could hold a laptop mount, which would put the screen on the seatback at a comfortable eye level. Should the person forward recline, you would want to be able to adjust the mount to keep the screen at the right angle. For laptops that can’t flip their screen, the keyboard etc. would just hang below, unused.
Instead, you would connect a remote keyboard/mouse device, which could then sit on your lap or the tray for comfortable use. And you would even have some room for papers on the tray. (This requires the mounting point to be above the tray.)
The airline could ideally provide or rent this small keyboard/mouse station, RFI insulated. In fact the arline one need not be so small, it could be full sized. Or stations in the airport (like the flight DVD rental folks) could rent the laptop mount and keyboard/pointer for drop off at the next airport. You want this because it defeats the purpose of having a small laptop to have to carry on a keyboard almost as big as the laptop.
Of course, laptops could be designed not only to hook into the mount, but have a detatchable keyboard/mouse unit so you don’t have to carry anything extra. Makes the laptop a bit bigger of course, but not much. Be nice if you could use bluetooth. Right now in theory bluetooth is not allowed but it’s in a safe band so it should not be a real problem.
This would still be useful in Economy Plus, even though there you don’t have the space crunch problem. A nice keyboard and an eye-height screen is how we like it on the desk. In Biz class, the seat in front might be too far away.
Another alternative would be provision of flat panels in the seat backs, with a VGA/DVI jack. Of course many airlines already are putting flat panels there, but only at TV resolution. Bump to XGA or better and now laptop users could keep their laptop on the table and look at the seatback. Many laptops even have a dual screen mode, so you could get double the screen real estate. Indeed, this is even valuable with a plain VGA class display in the seatback as already found. A port for that screen is also handy for the many people who use their laptops to play DVDs, though for those you want a 720x480 resolution screen which I don’t yet see in seatbacks.
If course power at the seats is a big plus, and some airlines do this, though UAL does not yet provide it in coach. The power should be in the seatback, not the armrest, since the thing we want to power is usually on the tray table.
A snap-out, aimable book reading white LED on the seatback would also be very useful. Aside from being cheap and consuming less power, this more localized light is less likely to interfere with sleepers and movie watchers. And by being aimable, it makes reading the book much more comfortable.
Let’s get to it, airlines.
I’m enjoying the new version of Battlestar Galactica. Unlike the original, which was cheezy space opera, this show is the best SF show on TV. Yes, I watched the original when I was 18. I knew it was terrible (and full of bad science) but in the 70s TV SF was extremely rare, and often even worse.
The original show began with Pactrick Macnee narrating an opening “There are those who believe that life here, began out there, with tribes of humans who may have been the forefathers of the Egyptians…” They sought the lost tribe of Earth, and in a truly abyssmal sequel finally came to 1980 Earth, which was of course technologically backward compared to them and unable to help in their fight.
This idea was a common one in science fiction of the 20th century. It was frequent in written SF, and Star Trek twice took it up. In one 60s episode, the Enterprise met Sargon, who claimed to have sewn most of the humanoid races. Spock states this meshes with Vulcan history, but another character says that Humans appear to have evolved on Earth. A later episode of Star Trek: The Next Generation reverses this, and Picard follows clues left in DNA to discover the common ancestry of all the humanoids.
Back in the 60s and 70s, when Battlestar Galactica and Star Trek were written, you could get away with this plot. It had a romantic appeal. While there was tons of evidence, as even Star Trek of the 60s knew, that humans were from Earth, we had not come to the 90s and the DNA sequencer. Today we know we share 25% of our DNA with cabbages. We’re descended from a long line in the fossil record that goes back a billion years. If life on this planet was seeded from other planets, it was over a billion years ago. It certainly wasn’t during the lifetime of Humanity, and nor were all the animals also seeded here at the same time as we were unless the aliens who did it deliberately created a fake fossil record.
(Of course creationists try very hard to make the case that this could be true, but they don’t even remotely succeed. If you think they do have a point, you may want to stop reading. You can read on for more SF theory though.) read more »
My Canon cameras have a variety of ways you can change their settings to certain specialty ones. You can set a manual white balance. You can set an exposure compensation for regular exposures or flash (to make it dimmer or brighter than the camera calculates it should be.) You can change various shooting parameters (saturation etc.) and how the images will be stored (raw or not, large/medium/small etc.) You can of course switch (this time with a physical dial) from manual exposure to various automatic and semi-automatic exposure modes. On the P&S cameras you can disable or enable flash with such settings. You can change shooting modes (single-shot, multi-shot.) You can turn on bracketing of various functions.
And let’s face it, I bet all of you who have such cameras have found yourself shooting by accident in a very wrong mode, not discovering it quite for some time. If you’re in a fast shooting mode, not looking at the screen, it can be easy to miss things like a manual white balance or even a small exposure compensations.
The camera already features an option to auto-revert on exposure bracketing, since they decided few would want to leave such a feature on full time. But auto bracketing isn’t dangerous, it just wastes a couple of shots that you can just delete later. And it’s also very obvious when it’s on. Of all the things to consider auto-revert for, this was the least necessary.
To my mind, the thing I would like auto-revert on most of all is manual white balancing. I recently was shooting fast an furious in a plane, and learned after lots of shots I still had the camera in an artificial light balance setting from the night before. The camera can do a good job here because it can usually tell what the temperature of the ambient light is, and can notice that the balance is probably wrong. In addition, it can tell that lots of time has passed since the white balance was set manually. It really should have a good idea if it’s out in daylight or indoors, if it’s night or day.
And I’m not even asking for an auto-revert here. Rather, an error beep which also pops a message on the screen that the white balance may be wrong. And yes, for those who don’t want this feature they can disable it. However, what would be cool would be if the screen that pops up to warn about a possibly bad retained setting, would be the ability then and there to say, “Thanks, revert” or “Don’t warn me about this again” or “Don’t warn me about this until the next ‘session.’” The camera knows about ‘sessions’ because it sees pauses in shooting with the camera off, and as noted, changes from night to day, indoors to out.
Of course it would still keep shooting. For extra credit if it suspected something wrong, it could hold the image in RAW mode in its buffer memory, and if you ask to go to another setting that only changes the jpegs, it could actually redo the jpeg right.
Now of course, photographers often shoot in manual modes for a very good reason, and they are doing it because they don’t want the camera’s automatic settings. But that doesn’t mean they can’t be reminded if, after a longish bout with the camera off, they are shooting in a way that’s very different from what the camera wants. That can include exposure. I’ve often left the camera in manual and then forgotten about it until I saw the review screen. (Of course P&S users almost always look at the review screen, they don’t get this trouble.) Again, I want the camera to shoot when I tell it to, but to consider warning me if I turn warnings on that the image is totally overexposed or underexposed. At night it would take a more serious warning since in night shots there often no “right” exposure to compare with.
A smart camera could even notice when you aren’t looking at the review screen, because you are shooting so fast. But like I said, those who want the old way could always turn such warnings off.
Another option would be an explicit button to say, “I’m going to make a bunch of specialty settings now. Please warn me if I don’t revert them at the next session.” This could extend even to warning you that you turned off autofocus. Review screens don’t show minor focus errors, so it would be nice to be reminded of this.
(I actually think an even better warning would be one where the camera beeps if nothing in the shot is in focus, as is often the case here. The camera can easily tell if there are no high contrast edges in the shot. Yes, there are a few scenes that have nothing sharp in them, I don’t mind the odd beep on those.)
People are always looking for location aware services for their mobile devices, including local info. But frankly the UIs on small mobile devices often are poor. When you are on a cell phone, voice to a smart person is the interface you often want.
So here’s a possible location aware service. Let people register as a “local expert” for various coordinates. That’s probably folks who live in a neighbourhood or know it very well. They would then, using a presence system on their own phone or computer, declare when they are available to take calls about that location.
Somebody sitting with a cell phone in a location could call a special 900-like number. Their phone could just transmit their location, or they would quickly say it to a human for entry. Then, their call would be routed to a local expert who is marked as available for calls. (In some cases it may simultaneously ring several experts of possible but unsure availability and give the call to whoever answers first.)
Then they could, for a fee (perhaps $1/minute?) ask the expert questions.
- “Where’s the best Thai food?”
- “How do I get transit to such and such location?”
- “What’s a good Taxi company to call? Can you call me one?”
- “Is there a shop around here that sells widgets?”
- “Is this museum worth it?”
- “What parts of the area are dangerous?”
- “How much is real estate here?”
The expert would be expected to know how to answer questions about most of the restaurants, bars and shops. And they could also — so long as they disclosed any kickbacks very clearly — provide coupon codes to people that would rebate the cost of the call.
At the end of any call, the caller would stay on the line and be asked to rate the quality of the expert. They could also rate later. Experts would gain reputations for their skill, and the ones with the highest ratings would be given more calls, or be able to charge more.
Charging could be per minute, fixed-rate, or as noted, rebated with validation from a recommended merchant (though I would want to design a system so that advice is never biased by this.)
This could also be done by texting, which would be easier for experts to do, and probably be cheaper, but of course is slower for the mobile user. Many mobile users are getting pretty good at their texting. The experts would presumably be at computers with IM clients, but they could be at mobile phones as well.
To make this cheaper, one could arrange for trading minutes. Which is to say, if you put minutes into the system advising others, you can in turn use minutes getting advice when you need it. Some people might prefer to do this in a friendly way rather than charge or pay.
Experts could very well be just around the corner, physically, if they are being an expert on their local neighbourhood. It’s not out of the question they could then agree to help in person. In this case you would need to have some way to certify they’re not up to something nefarious. The fact that the call is logged and you know the home address of the expert in the database should be enough. The client might be up to something nefarious, but this seems a pretty low risk.
Just on the heels of my prior post on the bad math often found around alternative energy, I see a Google Blog post on Google’s solar installation. It claims Google with save money with their 1.6 megawatt solar installation.
I would be very interested to see Google’s numbers — what are they paying for this PV system, and what do they pay the power company for their grid power? Did they get rebates on the PV install? Rebates can help a single customer save money but they do it at taxpayer expense which makes it a wash, other than as a means to try to increase the market for solar and bring down the price.
Now, I’m not in any way saying that it’s bad for Google to go solar. Large grid-tie solar arrays are quite green, with minimal emissions (only those from their manufacture, shipping and install) and so it’s good to have them, even if they are more expensive than non-green grid energy.
But I want to know, is my math bad, or is Google’s? If companies can really save money with a PV array they should be springing up like weeds.
Today I also read announcements of companies hoping to bring to market new solar panel technologies with thin films that are vastly cheaper than existing tech. When that happens, the panels really should sprout everwhere, and to very positive effect.
Update: The press releases say the system is 1.6MW, and provides 2.6 million khw/year for a saving of $393K per year (about 15 cents/kwh which is about right in California.) The press release also says the system will pay for itself in 7.5 years, which at 7% interest rate means its total cost was $2.2M. (Truth is Google is able to make far better than 7% with its money, I suspect.)
This means an astounding $1.38 per watt for installed solar. I’ve never heard of anything remotely like this. Even with a bad-math 0% interest rate, 7.5 year payoff is $1.84/watt so it’s not just bad math here. Even with the California rebates of $2.60/watt and 30% federal tax credit, it’s still amzingly cheap — and almost all the savings are coming from the taxpayer.
The release also suggests that 393K per year will result in 15 million saved over a 30 year lifespan. I can’t figure the math in this number. The bad-math 30*393 is under 12 million. The real saving over 30 years at 7% interest has a present value of 4.8 million. The future value, in 30 years time, of $393/year is well over 30M at 7%. You need an interest rate of 1.5% to have a FV near $15M. I suspose the risk-free-rate-above-inflation might correspond to this but it’s not typical in expressing these numbers.
So what are the real numbers?
Last week I wrote about how the 800 number you get on the web page should be special and understand your context and how frustrating it is to get an 800 number from the Contact-Us page on a web site and then be taken through a series of menus that are a waste of time for somebody who was just at the web site.
While the best thing to do is to get an eCRM system which connects the user with a session fully informed about what they were doing on the web, that’s expensive. However, a few more thoughts have come to me.
a) Most IVRs for large companies offer the choice to use a different language, such as Spanish or French, which is good. But if I was on the web site I probably made a language choice there. So the “Contact Us” page in Spanish should give an 800 number that doesn’t bother to ask me, and the “Contact Us” page in English should probably be the same.
b) “Listen carefully because some of our options has changed” is one of the biggest lies out there. By if the Contact-Us page is going to lead the customer to an IVR, why not offer a page with a basic diagram of the IVR menus. Yes, I would like it to include the “path to an agent” sequence, and I know many companies don’t want to provide that in order to keep costs down. But at the very least you can tell me about the other choices that will be on the menu, and the fact that after I press 3 I’m going to be entering my account number followed by a pound sign.
And when the options do change, you can update the web site menus, and put a date on them so we can spot if they are old.
c) Ideally, track what I’ve been doing in my web session. Did I just book a flight? Did I just place an order? Did I just try to place an order and fail? Your web server knows this stuff. Now for some reason I’m phoning. Look at what I did and if you can’t offer me a custom 800 number just for that, at least spell out my likely path through the IVR. For example, “To amend this order in a way that can’t be done HERE, Call 1-800-xxx-yyy, press 3, wait for voice and enter your order number 123456 and then the pound sign.” (Yes, it should know my order number if I just placed an order.)
