I observed that provided one considered “real” aardvarks and zebras — addresses that received good email amongst the spam — then aardvarks got 35% spam and zebras a mere 20%.

This has been widely picked up, first in the Guardian, and later in many other papers as well (even in Danish). However, many of these articles have got hold of the wrong end of the stick. So besides mentioning A and Z, it looks as if I should have published this figure from the paper as well…

… the point being that the effect I am describing has little to do with Z being at the end of the alphabet, and A at the front, but seems to be connected to the relative rarity of zebras.

As you can see from the figure, marmosets and pelicans get around 42% spam (M and P being popular letters for people’s names) and quaggas 21% (there are very few Quentins, just as there are very few Zacks).

There are some outliers in the figure: for example “3″ relates to spammers failing to parse HTML properly and ending up with “3c” (a < character) at the start of names. However, it isn’t immediately apparent why “unicorns” get quite so much spam, it may just be a quirk of the way that I have assessed “realness”. Doubtless some future research will be able to explain this more fully.

...doctored photographs are the least of our worries. If you want to trick someone with a photograph, there are lots of easy ways to do it. You don't need Photoshop. You don't need sophisticated digital photo-manipulation. You don't need a computer. All you need to do is change the caption.

The photographs presented by Colin Powell at the United Nations in 2003 provide several examples. Photographs that were used to justify a war. And yet, the actual photographs are low-res, muddy aerial surveillance photographs of buildings and vehicles on the ground in Iraq. I'm not an aerial intelligence expert. I could be looking at anything. It is the labels, the captions, and the surrounding text that turn the images from one thing into another. Photographs presented by Colin Powell at the United Nations in 2003.

Powell was arguing that the Iraqis were doing something wrong, knew they were doing something wrong, and were trying to cover their tracks. Later, it was revealed that the captions were wrong. There was no evidence of chemical weapons and no evidence of concealment. Morris's mockery of the sweeping interpretations made in Powell's photographs.

There is a larger point. I don't know what these buildings were really used for. I don't know whether they were used for chemical weapons at one time, and then transformed into something relatively innocuous, in order to hide the reality of what was going on from weapons inspectors. But I do know that the yellow captions influence how we see the pictures. "Chemical Munitions Bunker" is different from "Empty Warehouse" which is different from "International House of Pancakes." The image remains the same but we see it differently.

Change the yellow labels, change the caption and you change the meaning of the photographs. You don't need Photoshop. That's the disturbing part. Captions do the heavy lifting as far as deception is concerned. The pictures merely provide the window-dressing. The unending series of errors engendered by falsely captioned photographs are rarely remarked on.

Blue Box listeners,

Well, it's been a while. A long while. This summer turned out to be a bit crazier than Jonathan or I ever expected. The good news is that the renovation at my home is finally done and I've moved into my home office. The box of podcasting gear has come up from the basement. I'm not traveling for several weeks... so everything looks good to finally get the huge queue of back episodes out the door.

My goal this week is to get some of the older main shows out first followed by some of the excellent Special Editions that our volunteer production team has put together. If things work out the way I hope I should be getting you a show a day for the rest of the week. (We'll see.)

Thanks for your patience and continued interest in the show. We have very definitely not "podfaded"... and we'll be back with more shows and interviews in the weeks and months ahead! Thanks for continuing to listen.

Dan & Jonathan

"consumers hate tokens."

"Everyone wants to be the single federation platform for everyone else."

"Federation will never work. It won’t work because the single most important consumer Web applications in the world are scared of it. Banks hate the concept because it becomes a weakest link in the chain problem."

"Tokens don’t actually solve most security problems, like man-in-the-middle, phishing, and keystroke-logging malware."

"Oh yes, and finally, consumers are going to have to carry around 13 of them just to make sure they can log into whatever they need to log into since no one will federate."

"Global federation is nowhere near a solid concept in the consumer space, despite what the vendors will try to sell you."

"This is a long term problem. If you work on it and make any progress against it, you'll find yourself much smarter at the far end, than you were at the near end.

When I was in Norway about 5 years ago, I was there very close to the summer solstice. I was wandering around town at 2 o'clock in the morning and there was plenty of light out. You come to a sign that says New Minsk about 60 km and it points south.

And I ask the lady "what country is this?"

She scratched her head for a bit, and said "well I think its Norway"

I said "well who plows the roads?"

"well Norway does, but he have to pay them."

There is a triple boundary in this town that I was in between Norway, Finland and Russia.

But what I did there, was, I had a card about wallet size, I stuck it into a machine, I punched in four digits, and it gave me about 2,000 krone, whatever the hell that is.

Now there are a lot of participants in that transaction. When I put a card into that machine, punch in a pin, and it gurgles for awhile, and finally gives me, a fairly large amount of money. There are a lot of participants in that transaction. The bank that owned the machine that gave me the money, it gave some money away -- that bank wants it back. The pin is necessary to convince my own bank that I'm me. But I don't want my pin to be broadcast all over the world. My bank in the us, it hasn't really given out or taken in any money, really. But there is a lot of credits involved here. Somebody needs to charge somebody else for having more money available. Even though there was actually no cash transfer.

And the problem that I have in mind is
- who are all the participants in an ATM transaction?
- what do those participants need to satisfy their problems?
- how is that in fact done?

In a general way, does the atm system actually work in some reasonable sense? To which the answer is by the way: yes. The atm system damn well works. With extremely high reliability and accuracy. It surprises me. Its quite a bit different than voting machines.

When I'm not traveling, I like to work from home some days rather than endure the trek from Seattle to Redmond (although it's much better now that our own employee transit service has expanded into my neighborhood -- the existence of which is sad commentary on the availability and reliability of Seattle's public transit companies).

This means, of course, that I need fast and stable network connections. Comcast with their PowerBoost is working very well for me. But I just can't find a decent wireless router at all. My Lenovo T61p (with Intel 4965abgn adapter) just won't stay connected to my D-Link DIR-628 and IT'S DRIVING ME CRAZY! (Yes, I've tried various driver versions, from both Lenovo and Intel.)

My house is in an area with a lot of wireless activity -- sometimes I can see nine or ten SSIDs. I'm running draft N on 2.4GHz (which occupies two non-adjacent channels, currently 1 and 4), and I suspect the problem is collision interference. I could shift the router to 5.2GHz, which I probably would help, but then the rest of the computers in my house won't connect. Why, you ask? Well get this: the DIR-628 is part of D-Link's RangeBooster N family. So I stayed in the family and got two DWA-542 adapters for the desktop computers. Yet they only do 2.4GHz! Silly me, I assumed that being in the same family means full support of the router's capabilities.

I'm very tempted to replace my router again -- and I'm thinking that the best option is to get one with dual radios. That way I can move my T61p to 5.2GHz and replace the desktop adapters, while still having single-channel 802.11b/g on 2.4GHz for the Wii and my PlayStation Portable.

Now my request: tell me about your experience with home routers. What do you really like, and why? What should I buy?
