(Note I have a simpler article for those just looking for advice on how to get their Widescreen TV to display properly.)

Very commonly today I see widescreen TVs being installed, both HDTV and normal. Flat panel TVs are a big win in public places since they don't have the bulk and weight of the older ones, so this is no surprise, even in SDTV. And they are usually made widescreen, which is great.

Everybody's got old cell phones, which sit in closets. Why don't the wireless carriers let customers cheaply have two or more phones on the same line. That would mean that when a call came in, both phones would ring (and your landlines if you desire) and you could answer in either place. You could make calls from either phone, though not both at the same time.

(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.

3-D printing is getting cheaper. This week I saw a story about producing a hacked together 3-D printer that could print in unusual cheap materials like play-doh and chocolate frosting for $2,000. Soon, another 3-D technology will get cheap -- the 3-D body scan.

In one of my first blog posts, I wrote about virtual right-of-way, a plan to create dedicated right of way for surface rail and bus transit, but to allow cars to use the RoW as long as they stay behind, and never in front of the transit vehicle.

I proposed one simple solution, that if the driver has to step on the brakes because of a car in the way, a camera photographs the car and plate, and the driver gets a fat ticket in the mail. People would learn you dare not get into the right-of-way if you can see a bus/train in your rearview mirror.

Join me next Thursday (one-eleven) at the one-eleven Minna gallery in San Francisco to celebrate EFF's 16th year. From 7 to 10pm. Suggested donation $20. Stop by if you're at Macworld.

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 wrote earlier about the controversial topic of discriminatory pricing, where vendors try to charge different customers different prices, usually based on what they can afford or will tolerate. One particularly vexing type of such pricing is the mail-in rebate. Mail in rebates do two things. In their pure form, they give a lower price to people willing to spend some time on the bureaucracy. As such, they would work at charging richer customers more because richer customers tend to value time more than money compared to poorer customers.

I've thought digital picture frames were a nice idea for a while, but have not yet bought one. The early generation were vastly overpriced, and the current cheaper generation still typically only offer 640x480 resolution. I spend a lot to produce quality, high-res photography, and while even a megapixel frame would be showing only a small part of my available resolution, 1/4 megapixel is just ridiculous.

While I've written before about the trouble in making solar competitive with grid power, this is not true when the grid is being blown up by geurilla fighters on a regular basis. Over the past couple of years, Bechtel has been paid over 2 billion dollars, mostly to try to rebuild the Iraq electrical infrastructure. Perhaps it's not their fault that power is only on in Bagdadh for 2 hours a day after these billions have been spent -- but their might have been a better way.

I was seduced by Google's bribe of $20 per $50 or greater order to try their new Checkout service, and did some Christmas shopping on buy.com. Normally buy.com, being based in Southern California, takes only 1 or 2 days by UPS ground to get things to me. So ordering last weekend should have been low risk for items that are "in stock and ship in 1-2 days." Yes, they cover their asses by putting a longer upper bound on the shipping time, but generally that's the ship time for people on the other coast.

Last week, I wrote about new ideas for finding the lost. One I've done some follow-up on is the cell phone approach. While it's not hard to design a good emergency rescue radio if you are going to explicitly carry a rescue device when you get lost, the key to cell phones is that people are already carrying them without thinking about it -- even when going places with no cell reception since they want the phone with them when they return to reception.

This week I participated in this thread on Newcomb's Paraodox which was noted on BoingBoing.

The paradox:

A highly superior being from another part of the galaxy presents you with two boxes, one open and one closed. In the open box there is a thousand-dollar bill. In the closed box there is either one million dollars or there is nothing. You are to choose between taking both boxes or taking the closed box only. But there's a catch.

I've been writing recently about the linux upgrade nightmares that continue to trouble the world. The next in my series of ideas is a suggestion that we try to measure how well upgrades go, and make a database of results available.

I've spoken before about ZUI (Zero User Interface) and how often it's the right interface.

One important system that often has too complex a UI is backup. Because of that, backups often don't get done. In particular offsite backups, which are the only way to deal with fire and similar catastrophe.

Here's a rough design for a ZUI offsite backup. The only UI at a basic level is just installing and enabling it -- and choosing a good password (that's not quite zero UI but it's pretty limited.)

A new program has appeared at San Jose Airport, and a few other airports like Orlando. It's called "Clear" and is largely the product of the private company Clear at flyclear.com. But something smells very wrong.

To get the Clear card, you hand over $99/year. The private company keeps 90% and the TSA gets the small remainder. You then have to provide a fingerprint, an iris scan and your SSN, among other things.

Normally I'm a general-purpose computing guy. I like that the computer that runs my TV with MythTV is a general purpose computer that does far more than a Tivo ever would. My main computer is normally on and ready for me to do a thousand things.

But there is value in specialty internet appliances, especially ones that can be very low power and small. But it doesn't make sense to have a ton of those either.

Last week I wrote about linux's problems with dependencies and upgrades and promised some suggestions this week.

There are a couple of ideas here to be stolen from (sacrilige) windows which could be a start here, though they aren't my long term solution.

Microsoft takes a different approach to updates, which consists of little patches and big service packs. The service packs integrate a lot of changes, including major changes, into one upgrade. They are not very frequent, and in some ways akin to the major distribution releases of systems like Ubuntu (but not its parent Debian ), Fedora Core and SuSE.

Installing a service pack is certainly not without risks, but the very particular combination of new libraries and changed apps in a service pack is extensively tested together, as is also the case for a major revision of a linux distribution. Generally installing one of these packs has been a safe procedure. Most windows programs also do not use hand-edited configuration files for local changes, and so don't suffer from the upgrade problems associated with this particular technique nearly as much.

There is a story that Ikonos is going to redirect a satellite to do a high-res shot of the area where CNet editor James Kim is missing in Oregon. That's good, though sadly, too late, but they also report not knowing what to do with the data.

We still see a lot of thermal printers out there, particularly for printing labels, receipts and the like. They are cheap, of course, though the paper costs extra so it's not always a long term win.
