Towns lament the coming of big-box stores like Wal-Mart and Costco. Their cut-rate competition changes the nature of shopping and shopping neighbourhoods. To stop it, towns sometimes block the arrival of such stores. Now web competition is changing the landscape even more. But our shopping areas are still “designed” with the old thinking in mind. Some of them are being “redesigned” the hard way by market forces. Can we get what we really want?
We must realize that it isn’t Wal-Mart who closes down the mom’n’pop store. It’s the ordinary people, who used to shop at it and switch to Wal-Mart who close it down. They have a choice, and indeed in some areas such stores survive. read more »

I’ve written before about the problems with TV advertising. Recently I’ve been thinking more about the efficiency of various methods of advertising — to the target, not to the advertiser. Almost all studies of advertising concern how effectively advertising turns into leads or sales, but rarely are the interests of the target of the ad considered directly.
I think that has to change, because we’re getting more tools to avoid advertising and getting more resistant. I refuse to watch TV with ads, because at $1.20 per hour of advertising watched, it’s a horrible bargain. I would rather pay if I could, and do indeed buy the DVDs in many cases, but mostly my MythTV skips the ads for me. The more able I am to do this, the more my desires as a target must be addressed.
Advertising isn’t totally valueless to the target. In fact, Google feels one big reason for their success is that they deliver ads you might actually care to look at. There are other forms of advertising with the same mantra out there, and they tend to do well, such as movie trailers and Superbowl ads.
Consider a video ad lasting 30 seconds, with a $10 CPM. That means the advertiser pays one cent per viewer of the ad. The viewer spends 30 seconds. On the other hand, a box with 3 or 4 Google ads, as you might see on this page, is typically scanned in well under a second. These ads also earn (as a group) about a $10 CPM though they are paid per click. Google doesn’t publish numbers, but let’s assume a $10 CPM and a 1% click-through on the box. It’s actually higher than this.
In the 30 seconds a TV ad takes, I can peruse perhaps 50 boxes, bars or banners of web ads. That will expose me to over 100 product offers that in theory match my interests, compared to 1 for the video ad. The video ad will of course be far more convincing as it is getting so much attention, but in terms of worthwhile products offered to me per second, it’s terrible.
It isn’t quite this simple though, since I will click on one ad every every minute spent looking at ads (not every minute on the web) and perhaps spend another minute looking in detail at what the ad had to offer. That particular, very well targeted site, gains the wealth of attention the video ad demands, but far more efficiently.
I think this area is worth of more study in the industry, and I think it’s a less understood reason why Google is getting rich, and old media are running scared. In the future, people will tolerate advertising less and less unless it is clearer to them what value they are getting for it. Simply being able to get free programming is not the value we’re looking for, or if it is, we want a better deal — more programming in exchange for our valuable attention. But we want more than that better deal. We want to be advertised to efficiently, in a way that considers our needs and value. The companies that get that will win, the dinosaurs will find themselves in the movie “The Sixth Sense” — dead people, who don’t know they’re dead.

In the Temple of Five, #3 (D’Anna) seeks to see the faces of the Final Five. Cavil says “That can’t happen” and tries to shoot her. Later she is boxed for her quest (and also because the actress is only contracted for so many episodes, but we’ll ignore that.:-)
As she enters the projection, she looks with some surprise at the 5 robed figures laid out before her. Curiously, there are six drapes, but they stand on only 5 of them, leaving the one on her left empty. Then she approaches one with a look of shocked recognition and issues the apology:
You… Forgive me I…I had no idea
(By the way, in a nice irony, as she gives up everything to see the faces of the Final Five, two of them are outside, getting shot at by her own Centurions.) read more »

The human voice is a pretty versatile instrument, and many skilled vocalists have been able to do convincing imitations of other sounds, and we’ve all heard “human beat box” artists work with a microphone to do great sounds.
That got me thinking, could we train a choir to work together to sound like anything, starting with violins, and perhaps even a piano or more?
The idea would be to get some vocalists to make lots of sounds, both pure tones and more complex ones, and break them apart with spectrum analysis. Do the same for the target sound — try to break it up into components that might be made by human vocal cords with appropriate spectrum analysis.
Then find a way to easily add the human sounds together to sound like the instrument. Each singer might focus on one of the harmonics or other tonal qualities of the instrument. Do it first in the computer, and then see if the people can do it together, without being distracted. Then work on doing the attack and decay and other artifacts of the start and end of notes.
If it all worked, it would be a fun gag for a choir to suddenly sound like a piano or violin playing a popular piece. Purer tones like a flute might be harder than complex tones. Percussion is obviously possible though it might need some amplification. Indeed, amplification to adjust the levels properly might help a lot but would be slightly more artificial than hearing this without any electronics. Who knows, perhaps a choir could even sound like an orchestra playing the opening to Beethoven’s 5th, something everybody knows well.

My father was famously a preacher turned agnostic. We used to argue all the time about the difference between an agnostic and an athiest. I felt the difference was inconsequential, he felt it was important. And I’ve had the same argument with other proclaimed agnostics. I found an amusing way to sum up my view of it in one answer.
What is the difference between an atheist and an agnostic?
The difference is the atheist says she’s an atheist, while the agnostic says she’s an agnostic. read more »

If you’ve looked around, you probably noticed a high-def DVD player, be it HD-DVD or Blu-Ray, is expensive. Expect to pay $500 or so unless you get one bundled with a game console where they are subsidized.
Now they won’t follow this suggestion, but the reality is they didn’t need to make the move to these new DVD formats. Regular old DVD can actually handle pretty decent HDTV movies. Not as good as the new formats, but a lot better than plain DVD. I’ve seen videos with the latest codecs that pack a quite nice HD picture into 2.5 to 3 gigabytes for an hour. I’ve even seen it in less, down to 1.5 gigabytes (actually less that SD DVDs) at 720p 24 fps, though you do notice some problems. But it’s still way better than a standard DVD. Even so, a dual layer DVD can bring about 9 gb, and a double sided dual layer DVD gives you 18gb if you are willing to flip the disk over to get at special features or the 2nd half of a very long movie. Or of course just do 2-disk sets.
Now you might feel that the DVD industry would not want to make a new slew of regular DVD players with the fancier chips in them able to do these mp4 codecs when something clearly better is around the corner. And if they did do this, it would delay adoption of whatever high def DVD format they are backing in the format wars. But in fact, these disks could have been readily playable already, with no change, for the millions who watch DVDs on laptops and media center PCs. More than will have HD DVD or Blu-Ray for some time to come, even with the boost the Playstation 3 gives to Blu-Ray. read more »

One of my current peeves is just how much time we spend maintaining and upgrading computer operating systems, even as ordinary users. The workload for this is unacceptably high, though it’s not as though people are unaware of the problem.
Right now I’m updating one system to the beta of the new Ubuntu Feisty Fawn. (Ubuntu is the Linux distro I currently recommend.) They have done some work on building a single upgrader, which is good, but I was shocked to see an old problem resurface. In a 2 hour upgrade process, it asked me questions it didn’t need to ask me, and worse, it asked them at different times in the process. read more »

This year’s theme for Burning Man is “the Green Man.” It represents a lot of things. For many it just is an inspiration for art centered on nature or the environment. Others are taking it as a signal to try to be better environmentally. That’s going to be a very tough road for a festival centered on building a temporary city far from everything and pyrotechnic art.
So I wrote up some thoughts on the challenges involved. The toughest problem is that transporting an entire city to the desert and then taking it back is a great personal and artistic endeavour, but not one that can be considered green. All efforts to reduce the pollution at the event are dwarfed by the fuel burned to get there. So what can be done?

When I watch SF TV shows, I often try to imagine a backstory that might make the story even better and SF like. My current favourite show is Battlestar Galactica, which is one of those shows where a deep mystery is slowly revealed to the audience.
So based on my own thoughts, and other ideas inspired from newsgroups, I’ve jotted down a backstory to explain the results you see in the show. Of course, much of it probably won’t end up being true, but there are hints that some of it might.
In my Battlestar Galactica back-story I explain why
- Why everybody — even the so-called humans — is a Cylon
- Who the Final 5 are and what they are doing
- Why all this has happened before and is happening again
- How the Cylons were made, and where they got their biotech
Of course, ignore this if you don’t watch the show. It’s pure fanfic/speculation.
The show remains one of the great SF TV shows, though it has been bogging down of late. This timeline may be a plea to return the show to some good hard SF roots. Posthumanism and strife between humans and AIs are hot themes in modern SF, and BSG is most interesting if it’s set in our future with things to say about the relationship between man, machine and artificial biological intelligence.
Update: I have updated the article based on the season finale, which confirmed a number of my speculations though of course not all of them.

It’s nice to have a headset on your desk telephone, for handsfree conversations. A number of phones have a headset jack, either of the submini plug used by cell phones, or using a phone handset jack. Many companies buy headset units that plug into the handset line to provide a headset, some of them are even wireless.
But bluetooth headsets today are cheap, standardized and have a competitive market. And they are of course wireless. Many people already have them for their cell phone. I have seen a very small number of desk phones support having a bluetooth headset, and that shouldn’t be al that expensive, but it’s rare and only on high-end phones.
Here’s the idea: Put bluetooth headset support into the PBX. Bluetooth headsets can’t dial, they can effectively only go on-hook and off-hook with a single button. You would associate (in the PBX) your bluetooth headset with your desk phone. A bluetooth master would be not too far from your desk, and tied into the PBX, or into a PC that talks to the PBX. When your BT headset was in range of this master, it would be tied to ith with Bluetooth. (You would have to do an actual bluetooth pairing in advance. In addition, many people have bluetooth headsets normally linked to their cell phone, and call attempts from the headset go to the cell phone. The system would have to switch that over to the PBX.) read more »

When I watch the boundless energy of young children, and their parents’ frustration over it, I wonder how high-tech will alter how children are raised in the next few decades. Of course already TV, and now computers play a large role, and it seems very few toys don’t talk or move on their own.
But I’ve also realized that children, both from a sense of play and due to youthful simplicity, will tolerate some technologies far before adults will. For example, making an AI to pass the Turing Test for children may be much, much simpler than making one that can fool an adult. As such, we may start to see simple AIs meant for interacting with, occupying the minds of and educating children long before we find them usable as adults.
Another technology that young children might well tolerate sooner is virtual reality. We might hate the cartoonish graphics and un-natural interfaces of today’s VRs but children don’t know the interfaces aren’t natural — they will learn any interface — and they love cartoon worlds. read more »

I've ranted before about just how hard it has become to configure and administer computers. And there are services where you can hire sysadmins to help you, primarily aimed at novice users.
But we advanced users often need help today, too. Mostly when we run into problems we go to message boards, or do web searches and find advice on what to do. And once we get good on a package we can generally fix problems with it in no time.
I would love a service where I can trade my skill with some packages for help from others on other packages. There are some packages I know well, and could probably install for you or fix for you in a jiffy. Somebody else can do the same favour for me. In both cases we would explain what we did so the other person learned.
All of this would take place remotely, with VNC or ssh. Of course, this opens up a big question about trust. A reputation system would be a big start, but might not be enough. Of course you would want a complete log of all files changed, and how they were changed -- this service might apply more to just editing scripts and not compiling new binaries. Best of all, you could arrange to have a virtualized version of your machine around for the helper to use. After examining the differences you could apply to them to your real machine. Though in the end, you still need reputations so that people wanting to hack machines would not get into the system. They might have to be vetted as much as any outside consultant you would hire for money.
There seems a real efficiency to be had if this could be made to work. How often have you pounded for hours on something that a person skilled with the particular software could fix in minutes? How often could you do the same for others? Indeed, in many cases the person helping you might well be one of the developers of a system, who also would be learning about user problems. (Admittedly those developers would quickly earn enough credit to not have to maintain any other part of their system.)
The real tool would be truly secure operating systems where you can trust a stranger to work on one component.

Lots of people love model airplanes, and I bet they would love to simulate dogfights. They can't fire actual projectiles, as that would be dangerous, expensive, unworkable due to the weight and actually damage planes.
It should be possible to set up a system for dogfights using light, however. One way would be to have planes mount lasers that send out a coded pulse with a bit of dispersion, and have the other planes mount receivers with diffusers to pick up light from a lot of directions. It might be better to go in reverse, the way many shooting games do -- the planes broadcast a coded pulse from some bright LED in a specific colour and the "gun" is just a narrow sight that tries to pick up these pulses. When the gun gets one, it sends it down to the coordinator on the ground, and that tells the target plane it's been hit (possibly forcing it to leave the airspace after some number of hits, or impair the flying controls, etc.)
Of course you need authenticated equipment. If people provide their own it's too easy to cheat, and one could also just make a gun that has no barrel instead of a wide one, or have one on the ground. So some honour might be required here.
It would of course be hard to do, with no cockpit view. Some larger model planes can carry small video cameras for a more realistic dogfight of that sort, but I suspect people could figure something out. The gun could have sensors for the pulses that are wider than the actual "direct hit" sensor, allowing them to tell you when you're getting close, and even showing a screen on a laptop that is not a camera view from the plane but at least a view of how close you are to the target.

I wrote earlier about the bluetooth vibrator watch. I pushed this in part to promote the idea that phones should (almost) never ring. That ringing is rude to others and violates your own privacy, too.
Sony, Citizen and some others are now releasing bluetooth watches that go beyond this. Your watch should become a very small control station for your larger PDA/phone. Of course digital watches have a small screen, and there are also some nice analog watches where the background of the watch is secretly a screen. This should become cheaper with time.
As before, when a call comes in, your watch should gently vibrate or even just tingle your skin with a small charge. On the screen should be the caller-ID, and the buttons should be marked with choices, such as rejecting the call or accepting it. (These features will be in some of the upcoming bluetooth watches) If you accept it, the caller would hear you saying that you are getting out your real headset/handset and will talk to them in a few seconds. If you were in a meeting, they might be told it will be more than a few seconds, as you must excuse yourself from the room.
Your watch of course knows if it is on your wrist in many ways, including temperature, so the phone can know to actually ring if you’ve taken the watch off — for example when going to bed, if you want it to ring when you’re in bed, that is.
As the screens increase in resolution, they could also show things like the subject of emails and pages. No more pulling out the blackberry or cell phone — just a subtle glance at your watch when it tingles. Be nice if you can set your presence on your watch so that all calls go to voice mail, too.
Most flip phones have a 2nd small screen on them so you can see the time and caller-id when the phone is closed. This would not be needed if you use a watch like this, so the cost of the phone can be reduced to make up for the more expensive watch.
Your watch could also bind to your desk phone at the office. And the phone would also know if you are in the office or not.
Imagine a world of peace where you’re never hearing phones going off, and you aren’t seeing people constantly pulling out phones and blackberries to check calls and messages. Imagine a world where people no longer wear cell phones on their belts, either.
The watch could have a small headset in it too, but that would add bulk, and I think it’s better to pull out a dedicated one.
The only real downside to this — you would probably have to charge your watch once a week. This might not easily fit in with the smaller ladies’ watch designs. It should be possible in any larger design. E-ink technology, which takes no power to run a display, could also make a great material for the background of your watch dial, or even display a tolerable virtual watch dial for the many who prefer an analog set of hands. It might be necessary to design a protocol even lower power than bluetooth to give the watches even better battery life, and of course a standard charging interface found in hotels and offices would be great.
I think once this happens it will be hard to imagine how we tolerated it any other way. Yes, people get fun and status from their ringtones, but I think we can handle sacrificing that.
The watch could also be a mini-screen for a few other PDA and phone functions. For example, if you use a bluetooth earpiece, you can keep your phone in your pocket or purse, which is really nice, but sometimes you want a bit of display, for example to assist with voice command mode.
(Of course if you know about Voxable, you know I believe phone calls should simply not happen at all at the wrong times, but that’s a different leap.)

I have written several times before about Peerflix — Now that I’ve started applying some tags as well as categories to my items you can now see all the Peerflix stories using that link — and the issues behind doing a P2P media trading/loaning system. Unlike my own ideas in this area, Peerflix took a selling approach. You sold and bought DVDs, initially for their own internal currency. It was 3 “Peerbux” for new releases, 2 for older ones, and 1 for bargain bin disks.
That system, however, was failing. You would often be stuck for months or more with an unpopular disk. Getting box sets was difficult. So in December they moved to pricing videos in real dollars. I found that interesting because it makes them, in a way, much closer to a specialty eBay. There are still a lot of differences from eBay — only unboxed disks are traded, they provide insurance for broken disks and most importantly, they set the price on disks.
One can trade DVDs on eBay fairy efficiently but it requires a lot of brain effort because you must put time into figuring good bid and ask prices for items of inconsequential price. Peerflix agreed that this is probably a poor idea, so they decided to set the prices. I don’t know how they set their initial prices, but it may have been by looking at eBay data or similar information. read more »

Hey photo editing programs — I’m looking at you, Photoshop — a lot of you allow people to place text into graphic images, usually as a text layer. Most graphics with text on the web are made this way. Then we export the image as a jpeg or png/gif, flatting the layers so our artful text is displayed. This is how all the buttons with words are made, as well as the title banner graphics on most web sites.
So photo editors, when you render and flatten the layers, take the visible text (you know what it is) and include it in a tag inside the file, such as the EXIF information. Possibly as the caption if there isn’t already one. Let us disable this, including on just a single layer, but providing it would be a good default.
Then all the web spiders/search engines would be able to find that text. Web page editors could offer that text as a possible “alt” text for the graphic. And the blind would be able to have their web-page readers read to them the text embedded in graphics.

Recently I opened up a surprising can of worms with a blog post about CitizenRe wondering if they had finally solved the problem of making solar power compete with the electrical grid. At that post you will see a substantial comment thread, including contributions by executives of the firm, which I welcome. At first, I had known little about CitizenRe and the reputation it was building. I thought i should summarize some of the issues I have been considering and other elements I have learned.
CitizenRe’s offer is very appealing. They claim they will build a plant that can make vastly cheaper solar. Once they do, they will install it on your roof and “rent” it to you. You buy all the power it produces from them at a rate that beats your current grid power cost. Your risks are few — you put down a deposit of $500 to $1500 depending on system size, you must cover any damage to the panels, and they offer removal and replacement for a very modest fee if you need to reroof or even move. You lock in your rate, which is good if grid rates go up and bad if grid rates go down or other solar becomes cheaper, but on the whole it’s a balanced offer.
In fact, it seems too good to be true. It’s way, way cheaper than any offering available today. Because it sounds so good, many people are saying “show me.” I want to see just how they are going to pull that off. Many in the existing solar industry are saying that much louder. They are worried that if CitizenRe fails to deliver, all their customers will have been diverted to a pipedream while they suffer financial ruin. Of course, they are also worried that if CitizenRe does deliver, they will be competed out of business, so they do have a conflict of interest.
Here are some of the things to make me skeptical. read more »

(Note: I have posted a followup article on CitizenRe as a result of this thread.
Also a solar economics spreadsheet.)
I’ve been writing about the economics of green energy and solar PV, and have been pointed to a very interesting company named CitizenRe. Their offering suggests a major cost reduction to make solar workable.
They’re selling PV solar in a new way. Once they go into operation, they install and own the PV panels on your roof, and you commit to buy their output at a rate below your current utility rate. Few apparent catches, though there are some risks if you need to move (though they try to make that easy and will move the system once for those who do a long term contract.) You are also responsible for damage, so you either take the risk of panel damage or insure against it. Typically they provide an underpowered system and insist you live where you can sell back excess to the utility, which makes sense.
But my main question is, how can they afford to do it? They claim to be making their own panels and electrical equipment. Perhaps they can do this at such a better price they can make this affordable. Of course they take the rebates and tax credits which makes a big difference. Even so, they seem to offer panels even in lower-insolation places like New England, and to beat the prices of cheaper utilities which only charge around 8 cents/kwh.
My math suggests that with typical numbers of 2 khw/peak watt/year, to deliver 8 cents/kwh for 25 years requires an installed cost of under $2/peak watt — even less in the less sunny places. Nobody is even remotely close to this in cost, so this must require considerable reduction from rebates and tax credits.
A few other gotchas — if you need to re-roof, you must pay about $500 to temporarily remove up to 5kw of panels. And there is the risk that energy will get cheaper, leaving you locked in at a higher rate since you commit to buy all the power from the panels. While many people fear the reverse — grid power going up in price, where this is a win — in fact I think that energy getting cheaper is actually a significant risk as more and more money goes into cleantech and innovation in solar and other forms of generation.
It’s interesting that they are offering a price to compete with your own local utility. That makes sense in a “charge what the market will bear” style, but it would make more sense to market only to customers buying expensive grid power in states with high insolation (ie. the southwest.)
Even with the risks this seems like a deal with real potential — if it’s real — and I’ll be giving it more thought. Of course, for many, the big deal is that not only do they pay a competitive price, they are much greener, and even provide back-up power during the daytime. I would be interested if any readers know more about this company and their economics.
Update: There is a really detailed comment thread on this post. However, I must warn CitizenRe affiliates that while they must disclose their financial connection, they must also not provide affiliate URLs. Posts with affiliate URLs will be deleted.
Some salient details: There is internal dissent. I and many others wonder why an offer this good sounding would want to stain itself by being an MLM-pyramid. Much stuff still undisclosed, some doubt on when installs will take place.

A recent Forbes items pointed to my earlier posts on eBay Feedback so I thought it was time to update them. Note also the eBay tag for all posts on eBay including comments on the new non-feedback rules.
I originally mused about blinding feedback or detecting revenge feedback. It occurs to me there is a far, far simpler solution. If the first party leaves negative feedback, the other party can’t leave feedback at all. Instead, the negative feedback is displayed both in the target’s feedback profile and also in the commenter’s profile as a “negative feedback left.” (I don’t just mean how you can see it in the ‘feedback left for others’ display. I mean it would show up in your own feedback that you left negative feedback on a transaction as a buyer or seller. It would not count in your feedback percentage, but it would display in the list a count of negatives you left, and the text response to the negative made by the other party if any.)
Why? Well, once the first feedbacker leaves a negative, how much information is there, really, in the response feedback? It’s a pretty rare person who, having been given a negative feedback is going to respond with a positive! Far more likely they will not leave any feedback at all if they admit the problem was their fault. Or that they will leave revenge. So if there’s no information, it’s best to leave it out of the equation.
This means you can leave negatives without fear of revenge, but it will be clearly shown to people who look at your profile whether you leave a lot of negatives or not, and they can judge from comments if you are spiteful or really had some problems. This will discourage some negative feedback, since people will not want a more visible reputation of giving lots of negatives. A typical seller will expect to have given a bunch of negatives to deadbeat buyers who didn’t pay, and the comments will show that clearly. If, however, they have an above average number of disputes over little things, that might scare customers off — and perhaps deservedly.
I don’t know if eBay will do this so I’ve been musing that it might be time for somebody to make an independent reputation database for eBay, and tie it in with a plugin like ShortShip. This database could spot revenge feedbacks, note the order of feedbacks, and allow more detailed commentary. Of course if eBay tries to stop it, it has to be a piece of software that does all the eBay fetching from user’s machines rather then a central server.
