Recently I attended a panel that covered, among other things the universal service fund. This fund, which you usually see as an add-on on your phone bill, taxes urban phone users (through their interstate carriers) to subsidize local phone service for the poor, the rural, schools and health care. Sounds noble, but it collected over 5 billion dollars in 2002, and now the question has come about how to apply it to the internet now that people are making phone calls over the internet.
The panel was asked to explain the purpose of the fund, and they cited the various reasons above. There are people who live very far from cities to whom it would not be economical to run phone wires to at their real cost, etc. I suggested the purpose of the USF was to transfer money to the states of senators who support it from the states of senators who don’t.
Established telcos, who pay into the USF (though often also get paid out of it) are pushing to apply it to VoIP telcos. They want barriers to entry against the upstart competitors.
Why the cynical view? As I noted previously in the blog, friends and I decided last month to bring internet and phone service to Burning Man, in the Black Rock desert, which is about as rural and remote as it gets in the lower 48 states. We did it just for a lark, on the budget of just a few private individuals — admittedly richer than average individuals, but nowhere near corporate budgets.
We were able to do that through the use of the tons of revolutionary low cost technologies that have appeared due to the deregulation of unlicenced spectrum and VoIP. And the cost of that is just getting lower every day.
The truth is, today you can provide phone service to the poor, and schools, and hospitals, and a great deal of the rural, for a lower price than the urban people were getting “cheap” phone service when it was decided to tax it. And that trend is going to continue, especially if more spectrum is opened up to unlicenced use or cognitive radio use.
I conceive of a relatively cheap solar powered box with motorized directional antennas which could be dropped by helicopter on ridgetops for about $3,000 (and falling.) Somebody on the ground would aim the antennas to build a redundant mesh, and data/phone could reach just about anywhere cheaply, except the most remote corners of Alaska and a few other places. This is just one plan. The reality is that the exponential progress of bandwidth and radio technologies will provide others. Instead of taxing the new technologies and those deploying them, free them to get real results.

IPTV is the new buzzword for video over IP, in particular as it relates to DSL/phone companies wanting to compete with cable companies and give you TV using your DSL. (The cable companies are hard at work at giving you phone service over your cable modem.)
I saw a demo of Microsoft’s IPTV product recently. They talked about how they had this slick interface that could show you live thumbnails of what was on several other channels while a bigger box showed your current channel. They said how doing it all at the central server (which could get access to all the live streams independently, unlike a typical tuner card or cable box) allowed this fancy multiplexing.
But then I asked them, “So, do you still watch live TV?” They admitted that, like everbody else who gets a Tivo, MythTV, Ultimate TV or other PVR that they almost never watch live TV. So why demo something that’s the wave of the past? Mostly because it looks cool.
The dream of video on demand has been with us for decades and it’s a cool dream but a silly one. Sure, it would be nice to be able to pull up anything from a giant catalog and watch it, but it turns out that watching delayed, even much delayed is fine. “Netflix is video on demand with a very high latency,” I explained.
So why don’t the cable companies get it? They are going all out to bring us 30 megabit aDSL to deliver this, and that’s great for a lot of other apps, but it turns out that with a PVR, a more modest 3 megabit (or even 1 megabit) can give you TV just fine, with some latency. They should focus there instead of trying to put it all in the central server, where it will surely die.

Recently, I discovered something that others have known for a while but many don’t know. Namely that effectively all modern cars that say they should use Premium (high-octane) gasoline run perfectly fine on regular. Since the early 90s, cars have had more advanced carb/fuel-injector systems which adjust to the octane of the gas and don’t knock. Like an idiot, I’ve been filling my car with premium. The engineers at all the major car vendors have confirmed this.
I worked out that since the USA uses 370 million gallons of gas a day, or 135 billion per year, at 12% premium sales, that’s 16 billion gallons of premium sold, almost none of it needed. Call it 15B gallons. At a surcharge of 20 to 30 cents/gallon that’s over 3 billion extra dollars charged to no purpose in the USA, and presumably another 3 billion outside (though perhaps they buy less hi-test outside.) The USA uses about 44% of world gasoline.
So why do many cars come with a line in the owner’s manual saying to use premium gasoline? Turns out the marketing departments believe customers of higher-end cars are ethralled by horsepower. They want to advertise the highest peak horsepower number they can. And you can deliver a slightly higher peak horsepower on higher octane. Nothing so big that you would notice it outside of extreme driving conditions or pro racing, but you can publish a higher number. So long as you spec the car as using premium.
So to satisfy these marketing numbers, the world is spending about 6 billion extra bucks each year on high octane fuel. And I’m not even considering all the extra infrastructure required (fancier pumps and blending systems, more tanks with risk to leak into the ground etc.)
Many people think high-octane gasoline is “more powerful.” In fact, oddly, the octane rating measures how non-explosive the fuel is. The higher the octane, the less likely it will explode under pressure. People think of high-octane fuel as more powerful because with high octane fuel, you can design a higher performance car that works at higher compression, safe in the knowledge you won’t get explosions from anything but the spark plug, ie. knocking. The fuel is not higher power, it’s the engine, which is why putting premium into a regular car is a waste unless it’s knocking. Lead cheaply reduces knocking at low pressure which is why they used to add it until they realized, “holy crap, we’re filling our fuel with toxic lead!”
There is still controversy over whether high-compression engines get better mileage than when they run at lower compression with regular.
What a scam. Spread the word.

Klein Gilhousen, one of the founders of Qualcomm, proposed this evening at Gilder’s Telecosm that cell phones be modified, if an emergency shuts down the towers, to do some basic mesh networking, not so much for voice, but for text messaging and perhaps pust-to-talk voice packets, as well as location information from their internal GPS if present.
Thus, in New Orleans, everybody would have been able to text in and out, at a battery cost to those who relay the messages to the working cell towers. Texting doesn’t require continuous connectivity. In time, of course, towers would be repaired or they could be flow in on blimps or choppers.
I suggested that in fact this could be a commercially viable service, allowing people to text who are beyond the range of cell towers, possibly quite a bit beyond the range. Operators could still charge for this. (Others, more cynical, felt operators would never want stuff in phones that made them usable without the carrier.)
He also suggested some simple improvements. During Katrina, people who did get their cell phones out of town could not make calls because the databases that let them roam were “under water.” The databases need to be backed up, or more simply during an emergency, switch so that unknown phones are allowed to make calls if their home system does not respond, rather than blocking them.
This requires hardware mods, unfortunately (phones today can’t transmit and receive on the same bands) but otherwise is easy and could keep comms up in an emergency. A number of other cheap devices can keep power to phones.
Another person suggested phones have an ELT-like mode, where a person can enter a text message of the SOS form. Messages might indicate if the person is just advertising their location, or needs urgent help. Helicopters flying overhead could identify the phones, triangulate on them and locate all mobile owners who need rescue.

At every conference I go to, with a few rare exceptions, we always see people wasting time fiddling with computers and projectors in order to show their presentation, which is (sadly) almost always in
powerpoint. Many laptops won’t switch displays until they see a monitor on the VGA port, which makes things take longer.
So how about a wireless protocol for sending presentations from laptops to projectors or a computer connected to the projector. Over 802.11 or bluetooth, presumably.
Of course, if the presentation is powerpoint or other popular slideshow format, all this needs is a way to transmit the file, and then the control keystrokes. There are already protocols to do this for teleconferneces, where people in another city are watching the slides on their own computer, but I have not yet seen this used at a conference. There could also be a video protocol where the laptop screen is mirrored to the projector through an efficient screen transfer system. These already exist and are free (VNC, for example) but they could be improved by pre-sending the next slide, if it’s static, for instant transition. Fancy animations (which are a curse anywhere) and videos would be a bit slower but should be fine over a good network.
An authentication protocol would be needed, the speakers would get a passcode for access.
Of course, this can also be sped up if speakers are told to set up their laptop in advance, while the
prior speaker is speaking, with a good video switch that simulates a monitor so the laptop can be put into external mode. With a wireless protocol, some advance setup would be needed but it need not be on the stage.

In recent times, I and my colleagues at the Foresight Nanotech Institute have moved towards discouraging the idea of self-replicating machines as part of molecular nanotech. Eric Drexler, founder of the institute, described these machines in his seminal work “Engines of Creation,” while also warning about the major dangers that could result from that approach.
Recently, dining with Ray Kurzweil on the release of his new book The Singularity Is Near : When Humans Transcend Biology, he expressed the concern that the move away from self-replicating assemblers was largely political, and they would still be needed as a defence against malevolent self-replicating nanopathogens.
I understand the cynicism here, because the political case is compelling. Self-replicators are frightening, especially to people who get their introduction to them via fiction like Michael Chrichton’s “Prey.” But in fact we were frightened of the risks from the start. Self replication is an obvious model to present, both when first thinking about nanomachines, and in showing the parallels between them and living cells, which are of course self-replicating nanomachines.
The movement away from them however, has solid engineering reasons behind it, as well as safety reasons. Life has not always picked the most efficient path to a result, just the one that is sufficient to outcompete the others. In fact, red blood cells are not self-replicating. Instead, the marrow contains the engines that make red blood cells and send them out into the body to do their simple job.

Many are commenting on the gasoline shortages and price increases involved with hurricane evacuation and other emergencies. Some people can’t get gas to get out of the city. Others full up giant tanks even when they don’t need it. Stations raise prices as supply drops and demand increases, as per the normal rules of the market. Some suggest the stations be price-controlled to stop this, but that would only result in even more gas hoarding by the public.
The government could instead have a strategic emergency gasoline reserve. However, it need not keep this reserve in tanks, it could “keep” it in the storage tanks of all the private gas stations, by arranging a special emergency-based futures contract with the station owners, in advance. Not all stations need participate, as long as enough gas for evacuation can be reserved.
During the emergency, it would be calculated how much fuel will be needed per vehicle. Each station would provide that much fuel to each vehicle. The simplest way to do this is to devise some long-lasting mark that will last at least a few days to a week, and for each station to put it on a car after delivering the fuel. Perhaps something as simple as a sharpie mark or other semi-permanent mark on the gas cap. This is unfair in that people with multiple cars could get extra fuel, but other systems, like vouchers and databases have their own problems. Vouchers would be lost or sold on the black market, unfortunately.
Any fuel over and above the contracted amount could be sold at market prices to those who want more fuel and/or wish to hoard. Probably quite high market prices. Fuel tankers could also be arranged to resupply stations with emergency reserve needs. Note that the customers could still pay a normal price for the reserve gas, reducing the cost of the contract. They would also sign a voucher at the station, on which random audits could later be done to confirm compliance. Stations would contract to deliver based on the minimum reserve they keep in their own tanks. There could also be a true reserve in government owned tankers to cover the slop factor.

The reason that eBay paid such a huge price for Skype has now become clear. There were several companies competing to buy Skype, and just before the bidding closed, eBay decided the best way to win was to place a giant bid just a few seconds before the end. (This might be known as bid skyping.)
On a serious note, it has long been eBay policy, it is reported, to not want to facilitate communications between buyers and sellers, because they will just arrange to avoid eBay fees by selling outside eBay. Either this has changed, or the “obvious” parts of the plan — Skype presence on eBay auctions, “Skype the seller” buttons and so on, are not part of the value for eBay.

When I left high school, I didn’t look back. I have a few friends from HS, but mostly I found many more like minded people in university. That seems to be a male trait, in that more women seem to keep a circle of friends from HS than men do, but for those that find themselves at university, this is where the social circle that may stay with us our entire lives is formed.
However, today, university frosh, both male and female, and keeping in constant touch with their HS friends via instant messaging and VoIP. They don’t remove you from their buddy list because you went to different schools. This means they are keeping more and closer friends from their HS days and also are more in touch with life at other universities.
I expect this will have far reaching consequences, not all predictable today. To how people live their lives, how they socialize and go on vacations, and how aware they are of the world outside their new university life. With buddy list presence, these remote friends are gaining an intimacy in some ways higher that we used to give to local friends.

Attending a convention in the new Boston Convention and Exhibition Center (BCEC) I found one thing very surprising. The show organizer had to install wireless APs all around the building on poles, with long wires leading to power and ethernet. How can a new convention center not already be set up for wireless? I will admit, in some ways it is correct to anticipate that the radios that would do the work will be quickly obsolete, and thus should not be so permanently installed, but it seems crazy to me that a new CC would not have been built with spaces in the ceilings or upper walls ready for some sort of wireless network.
The meeting room halls also don’t have tons of power jacks in the floors. Today, at modern conventions, everybody brings laptops and they want to plug them in. Better conventions in older halls run extension cords and power strips, and there are a few of those here, but why should a new convention center not be ready to go?

Here at the VON conference, there’s lots of talk about numbering. While SIP had a dream of calling people using an E-mail address, the market has delivered devices with numeric keypads only, particularly in the mobile space. So nobody uses SIP URLs or domain names of any kind, and everybody worries about mapping to and from numbers. (Another thing Skype mostly ignored.) The regulators try to regulate VoIP by claiming they have the power when it makes calls to and from the legacy PSTN with its numbers.
But here’s something I learned putting out my free phone at Burning Man. Most of the people said, “I don’t know any of my friends’ numbers!” They did not have their cell phones or PDAs on them. The new generation of phone users is treating numbers as a one-time thing, to enter into the speed dial and forget. They know their own number, and perhaps a few other people, as well as their parents.
However, they do know how to TXT on a numeric keypad. So it makes me wonder, at least for the new generation, if the fuss about numbers is worth anything. What if we did switch back to names or SIP URLs (with short domains) and expected people to use various accelerated typing systems to enter numbers for the first time, and then have the phone remember after that.
One could easily create a service with an 800 number that let people dial it and then use digits to type in a SIP URL or e-mail address and connect to that person when not on their main phone. This is actually better, since even though it’s longer to type, it’s possible to remember it. On VOIP phones and Cell phones and smarter PSTN phones, people would switch to the names or speed dial. And the phone number would die the death it deserves.
More from VON later. VoIP is beyond heating up. As one speaker indicated, it’s past the tipping point. Its dominance over the PSTN is now assured. The only question is when it flips. People say things like, “And when the PSTN dies” here and nobody blinks. Though the regulators, pushed by the legacy lobby, still say things that make me throw my hands up in disgust. I asked Senator Sununu today if Congress had ever looked back and said, “I wish we had protected the legacy systems more?” To be fair, he’s one of the better members of congress on these issues.
Follow-up: Later at the conference, during the concert by Huey Lewis & the News, I thought it would be a nice romantic gesture to call home during his song “The Power of Love.” I suggested that to a friend whose cell phone battery had died and said she could use my phone. “I don’t know my boyfriend’s number. I am not even sure of the area code,” she said. Meanwhile others took cameraphone pictures of the performance and send them along with texted captions in similar romantic gestures. Mr. Lewis even took a cell phone from the audience and sang into it for whoever was on the other end.

Every time I take an RV trip (ie. each Burning Man) I come up with more observations. The biggest one is that it cost $360 in gasoline to go from the bay area to the black rock desert, about 800 miles. And that’s at a price still well below world price. The RV owner said he was planning to get out of the business, people no longer want to pay the gas price.
So why is it taking so long to produce a hybrid RV? Hybrid cars are great of course, but trucks and RVs are what really suck gas and need the improved efficiency. And they have the room for larger and more unusual engine configurations. Most of all, RVs also mostly come with expensive generators and batteries, and a hybrid RV would of course have a super duper power plant and batteries and inverters, presuming the engine was efficient at lower revs. The Hybrid RV’s power plant could also be a backup generator when parked at the non-moving home. Probably make the most sense with diesel fuel, or as I have suggested before, even the highly efficient stirling engine. (Stirlings are big, and take time to warm up, but an RV with batteries is fine with this.)
Every RV’s shower has this hose based showerhead with an on-off dial with a slight leak. Our camp built a much nicer shower using a standard kitchen sprayer. A kitchen sprayer with a lock-on would be much better and would make it easier to conserve water by letting you pulse water where you need it when rinsing.
Cleaning the RV, especially when back from the desert, is hard. RV renters charge fat cleaning deposits and fees. Why doesn’t some company that hires out housekeepers do an RV service. You could come to them. Drive in, and a team of 5 attacks your RV, cleaning it in minutes. Do it at a car wash to also handle the outside if needed. Espcially after Burning Man there’s a business here.
I’ve said these before: Paper towel racks, built-in soap dispensers, inverters, flourescent lights. Why aren’t these everywhere in the RV world, instead of being rare?
Stabilizers jacks are great, but how about something simpler, some way to lock the springs or shocks (of course with an interlock to prevent starting the vehicle!) And while slide-outs are great, why do we never see flip out beds the way pop-top campers have, or a pop-up on the cab-over bed? (Most RVs don’t have any spare wall space except in the master bedroom, which does limit the flip-out bed concept. You also almost never see murphy beds.) Flip-out beds don’t take away your dinette or couch as do the extra beds commonly found. And how about a seat belt design for use on the beds for safe sleeping while driving? You can do this now but it doesn’t seem super safe.

If you noticed a long break in the blogging, it’s because I was at Burning Man. And while people do blog from Burning Man, it’s not what you want to spend your time doing. I will have more entries in the future, but let me relate some stories of the network and the phone booth first.
Last year, we erected a free phone booth in the desert to great results. This year, it was going to be even better because of a plan for a new internet connection. In the past, John Gilmore had brought his satellite dish, which had all the latency and bandwidth limits of satellite. This year he splurged on getting a microwave link in, which will be even faster next year. Sadly, much of that money was wasted because we never got the “first mile” — the on-playa 802.11 network — operating at a satisfactory level. There was huge packet loss and jitter in most places, when it was up at all. Next time some of the money will go into better equipment and planning for the local network.
As such, the phone booth, located in our camp on 7:30, only worked intermittently and rarely with great voice quality. We eventually decided to sacrifice the aesthetic purity of a booth sitting in the desert, connected to nothing, and moved it on its wagon by trike to the center camp, home of the incoming microwave link. The we set it up on the street, with an ethernet wire snaking in. We were no longer wireless, but the voice quality was top notch. I wasn’t able to spend much time with it but reports were that the line got very long at times.
In our own camp, you could tell if it was working or not based on whether there was a line. Even waiting for it to work was better than the 2-3 hour time investment of taking the bus to the phone booth in Gerlach.
Last year, I recounted the emotional experience people had using an unexpected and impossible phone to hear the voices of loved ones. This year, this was magnified by Katrina. I learned of Katrina, in fact, when people came to ask to use the phone to contact their relatives in NOLA. (Read on…) read more »

You are probably familiar with Google adsense, which is providing the ads you see on the right hand side of this page. Adsense code examines the text of pages, and tries to match Google adwords bids against it. The publisher of the page gets some undisclosed share of the Google revenue.
Recently adsense has been improving a lot for me, and my revenue from it per day has more than doubled, either due to better ad placement, better share or higher bids — it’s hard to say. It has gotten good enough that one can now readily see making a living as a good web writer through adsense. At an extreme example, my Copyright Myths article, which is admittedly very popular, is now generating over $250 per month in revenue. Just that one article. An author able to generate articles that popular (admittedly difficult, part of the popularity comes from having been around for decades and being linked to from many places) could make a living wage.
On one hand, Adsense seems like a great implementation of the wall that is supposed to exist between advertising and editorial. I have no idea what ads will appear, I don’t control it. I have no relationship with the advertisers, and there are so many advertisers that it would be hard for any one of them to hold sway over me as a writer.
However, there is an opposite factor. Clearly some topics are much more lucrative than others. My jokes and photos pay just a small fraction of what writing on copyright pays, because there are lots of copyright lawyers willing to bid high to advertise to people curious about that topic. My spam essays pay decently because of anti-spam companies. My DNS essays get little traffic, but when they do they get people selling domain names etc.
In the extreme, if you become the big expert on a disease like mesothelioma, the asbestos caused disorder, laywers hoping to sign up clients will pay many dollars for every click. (It was famously the most expensive word in a survey last year.)
So there is a strong push now, for a writer wanting to make a living (instead of one like me getting some extra change) to write about the very specific topics that get high adwords or overture bids.
Part of this is nothing new. In the past the way to make the most profitable magazine was to cover a topic that would attract readers that advertisers want to reach. Some general media, like newspapers, sought only to gain an audience, and advertisers would pay to reach the general audience.
But advertisers don’t want to reach a general audience, or only rarely do they wish to do so. Google has broken one of the great aphorisms of advertising, “90% of all advertising is wasted, the problem is figuring which 90%.” And from this they have a multi-billion dollar business. But how will this affect editorial down the road?

A mantra in the security community, at least among some, has been that crypto that isn’t really strong is worse than having no crypto at all. The feeling is that a false sense of security can be worse than having no security as long as you know you have none. The bad examples include of course truly weak systems (like 40 bit SSL and even DES), systems that appear strong but have not been independently verified, and perhaps the greatest villian, “security through obscurity” where the details of the security are kept secret — and thus unverified by 3rd parties — in a hope that might make them safer from attack.
On the surface, all of these arguments are valid. From a cryptographer’s standpoint, since we know how to design good cryptography, why would we use anything less?
However, the problem is more complex than that, for it is not simply a problem of cryptography, but of business models, user interface and deployment. I fear that the attitude of “do it perfectly or not at all” has left the public with “not at all” far more than it should have.
An interesting illustration of the conflict is Skype. Skype encrypts all its calls as a matter of course. The user is unaware it’s even happening, and does nothing to turn it on. It just works. However, Skype is proprietary. They have not allowed independent parties to study the quality of their encryption. They advertise they use AES-256, which is a well trusted cypher, but they haven’t let people see if they’ve made mistakes in how they set it up.
This has caused criticism from the security community. And again, there is nothing wrong with the criticism in an academic sense. It certainly would be better if Skype laid bare their protocol and let people verify it. You could trust it more. Read on… read more »

Just back from a day at Bar Camp which was quickly put together as a tongue-in-cheek response to Tim O’Reilly’s Foo Camp and folks who had not been invited. Foo Camp is great fun, and Tim does it all for free, so it’s not suprising he has to turn people away — even me :-) — but Bar Camp was surprisingly good for something thrown together at the last minute with no costs.
It makes you wonder why some conferences have to cost so much. In Foo Camp, Tim provides his campus of course, which he already owns, and some rental facilities and most expensively, food, and lets people come free. Programming is ad-hoc, in recognition that at so many conferences, people come not because of the program but because of their fellow attendees. I haven’t asked Tim what it costs him per attendee but I suspect it’s much more modest than the fees at comparable conferences. People literally camp in empty cubicles and offices, though those not up for that can get hotel rooms or bring RVs.
Bar camp was even cheaper. Socialtext provided the office space in downtown Palo Alto. In just a short time, sponsors such as Technoratti and others provided all the food people could want, and attendees brought snacks and drinks. Fewer folks camped because it was in Silicon Valley, but some of the younger set did. Talks were quickly put together, but interesting, and covered whole ranges of new and interesting software developments. And as at Foo Camp and everywhere else, hallway conversation was the real action.
With the glut of office space in this valley, and in other places, such ad-hoc conferences should not be hard to set up. Nor should sponsors be hard to find for modest food and other needs. If people become interested in having a conference rather than a business, they can do for nothing what could cost $1000 per person and with less work.
Not that I wouldn’t enjoy going back to Foo Camp, but Bar was its own rewarding experience too.

I’ve called before for a system of Universal DC Power and I still want it, but there is a partial step we could take.
I have a laptop power supply that comes with a variety of tips. The tips tell (through something as simple as a resistor) the power supply how much voltage and current to supply for the laptop they are designed for. I bought mine for use in an airplane, others are sold that do both 12v and AC power.
I would like to see one designed for the corporate market, rather than the carry-around market. Ones to be left in offices and under conference tables, so that when somebody visits with a laptop, they can plug it in. No need to get out their own supply or eventually no need to bring it.
Unlike the carry-around where you pick your tip and leave the rest, this would have an array of tips, possibly rotating on a click-wheel, or all connected to a switch where one can dial the voltage/polarity/etc.
Some companies take more drastic steps. At Google for example, I notice they have standardized on thinkpads, and so all desks and conference tables have think pad supplies. Everybody is able to roam the building and be sure of laptop power. These supplies, while a bit more expensive, could solve the same problem.
An alternate would be to standardize the special tip that describes the power needed. Everybody could get a tip or pigtail for their laptop and carry just that around. Conference rooms could in fact have single supplies that let you plug in several of the pigtail. Of course that is halfway to my original proposal.
Now it turns out a considerable majority of laptops take either 16 volts or 19 volts. The main rebel is Dell, which uses funny plugs and often over 20v. Some need more current than others, I don’t know if any need current limiting or if simply making the PS capable of 100w would do the trick. Anyway, in this case, we could develop a standard 16v plug (the thinkpad one) and a different standard 19v plug (probably an HP one), in two different shapes and colours, and people with laptops could carry a cheap converter to plug their laptop into it. Over time, laptops might come directly able to use this, if they aren’t already — on our path to a smarter power bus. Then people could say, “Oh, you have the orange plug. Great, I can plug my laptop into that.” Vendors who make laptops that won’t plug into one of these two will probably think about switching.

Hot in the blogosphere these days, as a result of the Creationism/ID vs. Evolution debate is Pastafarianism, the worship of the Giant Flying Spaghetti Monster. The idea is to show that something as made up as the GFSM is as consistent as ID.
Now as I’ve written before, I think we should teach creationism and ID in the schools as an example of bad science. All students should learn how to identify when bad science and bad math (in particular bad stats) are being used to lie to them. They should take exams where they are given examples of bad science and must spot the flaws to pass.
However, never one to pass up a joke religion, I still think the Pastafari go too far. I propose Monolithism. (Perhaps monolitheism?).
Monolithism is a variation of Intelligent Design which proposes that man was given the gift of intelligent thought by giant black alien monoliths. They came to Earth long ago and are waiting out there for us to show them the results.
Now Monolithism has great visual aids already to show the process. It meets many of the requirements of I.D. except that most people know it’s a movie.
