I learned a couple of days ago my mail server got blacklisted by spamcop.net. They don't reveal the reason for it, but it's likely that I was blacklisted for running an autoresponder, in this case my own custom challenge/response spam filter which is the oldest operating one I know of.
I've written before about the desire for a new universal dc power standard. Now I want to rethink our systems of household and office power.
These systems range from 100v to 240v, typically at 50 or 60hz. But very little that we plug in these days inherently wants that sort of power. Most of them quickly convert it to something else. DC devices use linear and switched mode power supplies to generate lower voltage DC. Flourescent lights convert to high voltage AC. Incandescent bulbs and heating elements use the voltage directly, but can be designed for any voltage and care little about the frequency. There are a dwindling number of direct 60hz AC motors in use in the home. In the old days clocks counted the cycles but that's very rare now.
On top of that, most of what we plug in uses only modest power. The most commonly plugged in things in my house are small power supplies using a few watts. Most consumer electronics are using in the 50-200w range. A few items, such as power tools, major appliances, cooking appliances, heatters, vacuum cleaners and hairdryers use the full 1000 to 1800 watts a plug can provide.
So with this in mind, how might we redesign household and office power...
One particularly interesting argument seen in the Underwatergate scandal is the one that the NYT, by revealing the existence of warrantless wiretaps on international communications lines, compromised national security.
Reporters asked how that can be. After all, surely the bad guys knew the U.S. had the ability to perform surveillance on them, and has a secret intelligence court, and was presumably getting lots of secret warrants to watch them, and was furthermore watching them overseas without being subject to the 4th amendment.
I've written before about automatic self-driving cars, both their risks (overregulation due to fear of their use by terrorists) and possible driving forces (oil companies excited by people taking longer trips) and more.
Generally, except for a few specialized applications (such as the automatic parking lot) such cars, if they are to be used where people or cars that may not under network control are present, must start with a basic ability to avoid accidents. In a vigourous debate with friend Charles Merriam last night, the question came up about where the value will lie. Charles is a big proponent of worrying first about crash-avoiding cars.
Right now we all pay from $250 to $500 per year, and often much more, for insurance to cover the risk of accidents. Of course, that's just the financial cost, and financial proxies for suffering, so the real value we would put on an accident resistent car might be much higher. Perhaps $5,000 to $10,000 over the life of the car.
That seems like a highly lucrative market on its own. While the self-driving car has many other long term merits (because you can do other work while moving, and you don't have to park it, and it can appear on demand as a taxi for you) we should be very close to financially justifying the accident-avoiding car today...
The AP reports that the DoJ is going to investigate the Underwatergate "leak" to the New York Times. Many of course wish they would investigate the program instead, but since the AG was involved in it, that's difficult.
But this puts forward the complex problem of how to deal with, and stop, illegal classified programs. Because they are classified, they lack many of the checks and balances that exist for other government operations. Indeed, it is suspected that many programs get classified entirely or in part in order to avoid scrutiny.
I was visiting a senior citizen today who rarely leaves her house due to lack of mobility. Like many her age, she is not connected to the net, nor interested in it. Which makes the following idea a challenge.
Could we design a really engaging game/online community for seniors? Especially those who have had to give up much of their old community because of infirmity? They don't want to slay monsters like in Evercrack or Warcraft. They won't build objects like in Second Life.
Here's a festive idea for a robotics company -- a giftwrapping robot, able to take a standard, not particularly fragile rectangular box and perfectly giftwrap it.
This might be a viable product for online stores that offer giftwrapping options, but I think one decent market would be malls at Christmastime. Aside from making money charging for wrapping, it would be an attraction (expecially in Japan where they love gifts) that brought in shoppers. I suppose some might worry it could deprive the charities that sometimes do giftwrapping in malls of a fundraising opportunity.
All the shipping companies today support very nice package tracking with web interfaces that let you see your package move through all the depots. Some day they might even send you an alert when it's half an hour before delivery.
However, more than a few times I've wished for something else -- package redirection, either at the behest of the recipient or the shipper. I talked earlier about my Addresscrow system, which would let you change your alias to mean different addresses as you move around, but this is more than that.
A lot of new developments in the warrantless wiretap scandal. A FISA judge has resigned in disgust. A Reagan-appointed former DoJ official calls the President a clear and present danger. And the NSA admits they have on rare occasions tapped entirely domestic phone calls, because sometimes people calling to or from international cell phones while those phones are in the USA would see the traffic go overseas and come back again. I have made such calls to Europeans and Australians visiting the USA.
It's long, but I can strongly recommend the transcript of today's press briefing on the NSA warrentless wiretaps. It's rare to see the NSA speak about this topic.
One can read a fair bit between the lines. The reporters were really on the ball here, far more than one usually sees.
Particularly interesting notes include:
Major retail chains Target, Wal-Mart and others announced today they will end the so-called war on white people that had resulted in most stores posting signs welcoming "shoppers" or "customers" instead of "white patrons", even though white people represented a considerable majority of their business.
In the summer we did a road trip in the northwest, up to Calgary, through Banff in the summer and then to Oregon Country Fair. The photojournal is not yet ready, but I have prepared some of the panos. First, here is the Montana section, which means the Going to the Sun road through Glacier National Park. Truly one of the world's great roads, I'm afraid the panos don't do it justice.
Ok, so this story is almost surely just an unconfirmed rumour, but the graphic I designed below still makes a nice ribbon.
I don't know how many times I've gotten a scrape or cut from hitting a dishwasher door, while it's down, with my leg. It's very annoying how the sides are always sharp. They don't make the seal, that's on the front, so there's no reason these sides couldn't be soft, or even hard rubber that won't cut you. Perhaps some dishwashers I haven't owned do this, but I have yet to get one!
Millions now use PCs for VoIP and online audio chat, and you soon realize the quality is vastly better if everybody uses a headset.
But there's a problem on PCs. If you plug in headphones, it usually disables the regular speakers, often in hardware. So if you leave a headset connected, the system can't play a ring sound when somebody calls you.
I just got an invitation to a new event series that I was told would take place on the First Tuesday of the month. However, I already go to two different dinners that take place on the First Tuesday, and I suspect that was no accident. For social events, people use the weekends, and for other events people prefer the weekdays. They have a psychological desire for the first week of the month.
So I ran a quick set of yahoo queries to find out how many hits there were on the web for "first monday" and similar strings. I figured that would tell when the most events do occur, and help people pick a day that is likely to have the least conflicts.
The results are below:
I've been thinking more about environmental economics since I blogged about retail carbon credits. I was surprised about how cheap (some would say unrealisticly cheap) wholesale credits are -- about $2.20 per tonne of CO2. (Update: This price keeps changing. The U.S. price is clearly out of whack down to just 25 cents per tonne in 2009. The European price has declined too, from $20/tonne when I wrote this to $14/tonne in fall 2009.)
Today, many of my friends have bought a car like the Toyota Prius, feeling they are doing their bit to help the environment by burning less gas. The Prius costs around $3,000-$6,000 more than a comparable old-style engine car (in part because high demand keeps the price high), and the savings on gasoline don't justify it on a financial basis unless you do nothing but drive all day. So the main reason to buy it is to help the environment and to make a statement before your peer group. The Camry Hybrid, which gets 32mpg instead of 23mpg costs about $5,000 more than the regular Camry.)
Problem is, there's an argument that you're hurting the environment, counterintuitive as that sounds. And no, it's not just the unanswered questions about recycling the fancy batteries in the Prius when they fade, where fairly positive results have been returned so far. Read on...
This is an idea from several years go I've never written up fully, but it's one of my favourites.
We've seen lots of pushes for online identity management -- Microsoft Passport, Liberty Alliance and more. But what I want is for the online world to help me manage my physical identity. That's much more valuable.
I propose a service I call "addrescrow" which holds and protects your physical address. It will give that address to any delivery company you specify when they have something to deliver, but has limits on how else it will give away info from you. It can also play a role in billing and online identity.
You would get one or more special ID names you could use in place of your address (and perhaps your name and everything else) when ordering stuff or otherwise giving an address. If my ID was "Brad Ideas" then somebody would be able to send a letter, fedex or UPS to me addressed simply to "Brad Ideas" and it would get to me, wherever I was.

I have been quite behind in processing my photo galleries and panoramics.
I have just now put up the gallery of panoramics from the Death Valley Wildflowers trip from March of 2005. Interesting scenery, and when you get close enough lots of fields of flowers. Of course, on most of them the flowers are so tiny that they are resolved well only when the panos are seen printed at full resolution, not when shrunk for a computer screen.
