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.

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.

I think it's important that we stop burning petrofuels or indeed any fuels and get energy from better sources.

But there's a disturbing phenomenon I have seen from people who believe the same thing too much. They want to believe so much, they forget their math. (Or I may be being charitable. Some of them, trying too hard to sell an idea or a product, may be deliberately forgetting their math.)

I see this over and over again in articles about photovoltaic solar, wind and other forms of power. They suggest you could put in a PV panel array for $20,000, have it provide you with $1,000 worth of electicity per year and thus "pay for itself" in 20 years. Again and again I see people take a series of payments that happen over a long time and just divide the total by the monthly or annual amount.

When you call most companies today, you get a complex "IVR" (menu with speech or touch-tone commands.) In many cases the IVR offers you a variety of customer service functions which can be done far more easily on the web site. And indeed, the prompts usually tell you to visit the web site to do such things.

However, have we all not shouted, "I am already at your damned web site, I would not be calling you to do those things!"

Every driver of a regular car knows this frustration well. You're behind a big SUV or Minivan and you can no longer see what's happening ahead of you, the way you can with ordinary cars. This is not simply because the ordinary cars are shorter, it's because you can see through the windows of the ordinary car -- they are at your level.

We should all be disturbed by the story of a man who was questioned and missed his flight because he spoke on his cell phone in Tamil. Some paranoid thought it was suspicious, reported it, and so the guy gets pulled and misses his flight.

This is not the first time. People have been treated as suspicious for speaking in all sorts of languages, including Arabic, Hebrew, Urdo or just being Arabs or Sikhs. Sometimes it's been a lot worse than just missing your flight.

More cars are being made "drive-by-wire" where the controls are electronic, and even in cars with mechanical steering, throttle and brake linkages, there also exist motorized controls for power steering and cruise control. (It's less common on the brakes.)

As this becomes more common, it would be nice if one could pop in a simple, short duration control console on the passenger's side. It need not be large, full set of controls, it might be more of the video game console size.

Some time ago I modified this blog softare (Drupal) to ask a very simple question of people without accounts posting comments. It generally works very well at stopping robot posting, however the volume of spam has been increasing, so I changed the question. Volume may have dropped a touch but I still got a bunch, which means the spammers are actually live humans, not robots.

As most people in the VoIP world know, the FCC mandated that "interconnected" VoIP providers must provide E911 (which means 911 calling with transmission of your location) service to their customers. It is not optional, they can't allow the customer to opt out to save money.

It sounds good on the surface, if there's a phone there you want to be able to reach emergency services with it.

The meaning of interconnected is still being debated. It was mostly aimed at the Vonages of the world. The current definition applies to service that has a phone-like device that can make and receive calls from the PSTN. Most people don't think it applies to PBX phones in homes and offices, though that's not explicit. It doesn't apply to the Skype client on your PC, one hopes, but it could very well apply if you have a more phone like device connecting to Skype, which offers Skype-in and Skype-out services on a pay per use basis and thus is interconnected with the PSTN.

Here's the kicker. There are a variety of companies which will provide E911 connectivity services for VoIP companies. This means you pay them and they will provide a means for you to route your user's calls to the right emergency public service access point, and pass along the address the user registered with the service. Seems like a fine business, but as far as I can tell, all these companies are charging by the customer per month, with fees between $1 and $2 per month.

This puts a lot of constraints on the pricing models of VoIP services. There's a lot of room for innovative business models that include offering limited or trial PSTN connection for free, or per-usage billing with no monthly fees. (All services I know of do the non-PSTN calling for free.) Or services that appear free but are supported by advertising or other means. You've seen that Skype decided to offer free PSTN services for all of 2006. AIM Phoneline offers a free number for incoming calls, as do many others.

It's common in the blogosphere for bloggers to comment on the posts of other bloggers. Sometimes blogs show trackbacks to let you see those comments with a posting. (I turned this off due to trackback spam.) In some cases we effectively get a thread, as might appear in a message board/email/USENET, but the individual components of the thread are all on the individual blogs.

At the blogger panel at Fall VON (repurposed to be both video on the net as well as voice) Vlogger and blip.tv advocate Dina Kaplan asked bloggers to start vlogging. It's started a minor debate.

My take? Please don't.

In an earlier blog post I attempted to distinguish TVoIP (TV over internet) with IPTV, a buzzword for cable/telco live video offerings. My goal was to explain that we can be very happy with TV, movies and video that come to us over the internet after some delay.

Trade show booths are always searching for branded items to hand out to prospects. Until they fix the airport bans, how about putting your brand on a tube of toothpaste and/or other travel liquids now banned from carry-on bags?

(Yeah, most hotels will now give you these, but it's the thought that counts and this one would be remembered longer than most T-shirts.)

As a hirsute individual, I beg the world's makers of medical tapes and band-aids to work on an adhesive that is decent at sticking to skin, but does not stick well to hair.

Not being versed in the adhesive chemistries of these things, I don't know how difficult this is, but if one can be found, many people would thank you.

Failing that would be an adhesive with a simple non-toxic solvent that unbinds it, which could be swabbed on while slowly undoing tape.

While it will be a while before I get the time to build all my panoramas of this year's Burning Man, I did do some quick versions of some of those I shot of the burn itself. This year, I arranged to be on a cherry picker above the burn. I wish I had spent more time actually looking at the spectacle, but I wanted to capture panoramas of Burning Man's climactic moment. The entire city gathers, along with all the art cars for one shared experience. A large chunk of the experience is the mood and the sound which I can't capture in a photo, but I can try to capture the scope.

I'm back fron Burning Man (and Worldcon), and though we had a decently successful internet connection there this time, you don't want to spend time at Burning Man reading the web. This presents an instance of one of the oldest problems in the "serial" part of the online world, how do you deal with the huge backup of stuff to read from tools that expect you to read regularly.

One of the few positive things over the recent giant AOL data spill (which we have asked the FTC to look into) is it has hopefully taught a few lessons about just how hard it is to truly anonymize data. With luck, the lesson will be "don't be fooled into thinking you can do it" and not "Just avoid what AOL did."

You probably heard yesterday's good news that the ACLU prevailed in their petition for an injunction against the NSA warrentless wiretapping. (Our case against AT&T to hold them accountable for allegedly participating in this now-ruled-unlawful program continues in the courts.)

However, the ruling was appealed (no surprise) and the government also asked for, and was granted a stay of the injunction. So the wiretaps won't stop unless the appeal is won.

But this begs the question, "Why do you need a stay?"

Last week at ZeroOne in San Jose, one of the art pieces reminded me of a sneaky idea I had a while ago. As you may know, many camcorders, camera phones and cheaper digital cameras respond to infrared light. You can check this out pretty easily by holding down a button on your remote control while using the preview screen on your camera. If you see a bright light, you're camera shoots in infrared.

Everybody's pulling out IBM PC stories on the 25th anniversary so I thought I would relate mine. I had been an active developer as a teen for the 6502 world -- Commodore Pet, Apple ][, Atari 800 and the like, and sold my first game to Personal Software Inc. back in 1979. PSI was just starting out, but the founders hired me on as their first employee to do more programming. The company became famous shortly thereafter by publishing VisiCalc, which was the first serious PC application, and the program that helped make Apple as a computer company outside the hobby market.
