An instant temporary internet kit

Over the weekend I was at the [BIL conference]http://www.bilconference.com, a barcamp/unconference style justaposition on the very expensive TED conference. I gave a few talks, including one on self driving cars, privacy and AI issues.

The conference, being free, was at a small community center. This location did not have internet. Various methods were possible to provide internet. The easiest are routers which can take cellular network EVDO cards and offer an 802.11 access point. That works most places, but is not able to handle many people, and may or may not violate some terms of service. However, in just about all these locations there are locations very nearby with broadband internet which can be used, including hotels, businesses and even some private homes. But how to get the access in quickly?

What would be useful would be an "instant internet kit" with all you need to take an internet connection (or two) a modest distance over wireless. This kit would be packed up and available via courier to events that want internet access on just a couple of days notice.

What would you put in the kit?

A universal Web-USB plugin for all browsers

As our devices get more and more complex, configuring them gets harder and harder. And for members of the non-tech-savvy public, close to impossible.

Here's an answer: Develop a simple browser plug-in for all platforms that can connect a USB peripheral to a TCP socket back to the server where the plugin page came from. (This is how flash and Java applets work, in fact this could be added to flash or Java.)

Predictive traction control

Yesterday I wrote about predictive suspension, to look ahead for bumps on the road and ready the suspension to compensate. There should be more we can learn by looking at the surface of the road ahead, or perhaps touching it, or perhaps getting telemetry from other cars.

Predictive suspension

I'm not the first to think of this idea, but in my series of essays on self driving cars I thought it would be worth discussing some ideas on suspension.

Driven cars need to have a modestly tight suspension. The driver needs to feel the road. An AI driven car doesn't need that, so the suspension can be tuned for the maximum comfort of the passengers. You can start bu just making it much softer than a driver would like, but you can go further.

Virtual machines need to share memory

A big trend in systems operation these days is the use of virtual machines -- software systems which emulate a standalone machine so you can run a guest operating system as a program on top of another (host) OS. This has become particularly popular for companies selling web hosting. They take one fast machine and run many VMs on it, so that each customer has the illusion of a standalone machine, on which they can do anything.

Laptops could get smart while power supplies stay stupid

If you have read my articles on power you know I yearn for the days when we get smart power so we have have universal supplies that power everything. This hit home when we got a new Thinkpad Z61 model, which uses a new power adapter which provides 20 volts at 4.5 amps and uses a new, quite rare power tip which is 8mm in diameter. For almost a decade, thinkpads used 16.5 volts and used a fairly standard 5.5mm plug. It go so that some companies standardized on Thinkpads and put cheap 16 volt TP power supplies in all the conference rooms, allowing employees to just bring their laptops in with no hassle.

Lenovo pissed off their customers with this move. I have perhaps 5 older power supplies, including one each at two desks, one that stays in the laptop bag for travel, one downstairs and one running an older ThinkPad. They are no good to me on the new computer.

Lenovo says they knew this would annoy people, and did it because they needed more power in their laptops, but could not increase the current in the older plug. I'm not quite sure why they need more power -- the newer processors are actually lower wattage -- but they did.

Here's something they could have done to make it better.

The impact of Peer to Peer on ISPs

I'm a director of BitTorrent Inc. (though not speaking for it) and so the recent debate about P2P applications and ISPs has been interesting to me. Comcast has tried to block off BitTorrent traffic by detecting it and severing certain P2P connections by forging TCP reset packets. Some want net neutrality legislation to stop such nasty activity, others want to embrace it. Brett Glass, who runs a wireless ISP, has become a vocal public opponent of P2P.

Some base their opposition on the fact that since BitTorrent is the best software for publishing large files, it does get used by copyright infringers a fair bit. But some just don't like the concept at all. Let's examine the issues.

A broadband connection consists of an upstream and downstream section. In the beginning, this was always symmetric, you had the same capacity up as down. Even today, big customers like universities and companies buy things like T-1 lines that give 1.5 megabits in each direction. ISPs almost always buy equal sized pipes to and from their peers.

With aDSL, the single phone wire is multiplexed so that you get much less upstream than downstream. A common circuit will give 1.5mbps down and say 256kb up -- a 6 to 1 ratio. Because cable systems weren't designed for 2 way data, they have it worse. They can give a lot down, but they share the upstream over a large block of customers under the existing DOCSIS system. They also will offer upstream on near the 6 to 1 ratio but unlike the DSL companies, there isn't a fixed line there.

Whose call is it to say what's legal?

As many of you will know, it's been a tumultuous week in President Bush's battle to get congress to retroactively nullify our lawsuit against AT&T over the illegal wiretaps our witnesses have testified to. The President convinced the Senate to pass a bill with retroactive immunity for the phone companies -- an immunity against not just this but all sorts of other illegal activities that have been confirmed but not explained by administration officials. But the House stood firm, and for now has refused. A battle is looming as the two bills must be reconciled.

Where are the savoury chocolate/cocoa dishes?

I've read studies that say that "chocolate" is the world's favourite flavour. That's not too surprising. Coming from central America after the Spanish conquest, the candy at least quickly was adopted all over Europe and to a lesser degree elsewhere. So did many other new world ingredients, such as corn, beans, squash, chiles, potatoes, vanilla, tomatoes, peanuts and many others. And we've seen many of these become common, and even essential ingredients in many overseas cuisines.

Rental car that personalizes to you

Rental car companies are often owned by car manufacturers and are their biggest customers. As cars get more and more computerized, how about making rental cars that know how to personalize to the customer?

When Hertz assigns me a car, they could load into its computer things like the dimensions of my body, so that the seat and mirrors are already set for me (simply remembered from the last time I rented such a car, for example.) If I have a co-driver, a switch would set them for her. The handsfree unit would be paired in advance with my bluetooth phone.

I'll pay a lot for the ultimate tourist's mobile device

Fast internet access at home has spoiled me. Like Manfred Macx in Tourist I feel like I've lost my glasses when I'm a tourist. I get annoyed that I can't quickly and easily get at all the information that's out there.

Put my PIN into the phone number

When you call to get your voice mail, even from your cell phone, it typically asks for a PIN. There's a reason for that -- there is no authentication on Caller ID, and anybody can forge it. So if you don't require a PIN, and the voice mail let you in directly, anybody could listen to your voice mail or hack it in other ways.

Detecting bad photos in camera and after

As I've noted, with digital cameras we all take tons of photos, and the next task is to isolate out the winners. I've outlined better workflow for this and there are still more improvements we need in photo management software, but one task both cameras and photo management software could make easier is eliminating the plain bad shots.

Automatic retracting pen

I put pens in my pockets. However, sometimes I put them in without caps, or I put in retractable pens without retracting them to keep the tip inside.

The result, as all who do this know, is from time to time a pen leaks out and ruins a pair of pants, sometimes more than that. It's expensive, and hard to solve. Since the earliest days the badge of the nerd has been the shirt pocket protector, but I put them in my pants. You could try tyvek pocket liners, I suppose, but it's hard to see how to easily add them.

eBay has announced sellers will no longer be able to leave negative feedback for buyers. This remarkably simple change has caused a lot of consternation. Sellers are upset. Should they be?

A plane that goes on a train

As I noted, at DLD Lufthansa had a contest (which I won) for suggestions on how to innovate to compete with trains. They set the time horizon out 15 years, which really means a lot is possible, so while I mostly threw in ideas from this blog which are short term, I put in some longer term ones too.

One was the equivalent of "multi modal transport." To do this, you would build new short-haul planes which consisted of an empty shell, like the cargo planes you have seen where the nose hinges up, and cargo modules are slid in on rails. This would be combine with "passenger modules" which can slide into the shell, and which can also slide into a special rail car. There might be one module on a plane, though it is also possible to have several.

Passengers would board a train normally at the train station. Then, as the train moved to the airport, they could move to the passenger module car. They would place their luggage onto a belt to put it down low into the luggage module (under the passenger module) or be assisted by a porter. They would enter the passenger module, stow their carry-ons and otherwise get ready in their seat. By the time the train got to the airport, all passengers would be in their seats, belted and ready.

The train would split up into different cars if there were several flights on it, and each would move to a terminus where the plane-shell was waiting. Yet to be invented technology would laser-align the train and the parked shell in advance, and then the passenger module would slip into the aircraft hull on special rails. Connecting passengers could board the train at the airport before it moves to the hull, and their bags could be loaded into the bottom the standard way. (Though this is for short-haul flights, so there may not be connecting passengers.) An automated system would connect power, data and air venting on the passenger modules. Water/sewage would be self-contained and processed at the train station. Catering would probably be handled there too.

The nose would come down, the pilots board via their own door and takeoff would begin shortly.

German Ideas

I'm back from my German trip, which included the DLD conference and a bit of touring in Austria and Bavaria. DLD was a good crowd of people and speakers, though the programming was a bit of a mishmash. I'll have some nice photos up soon.

A new social networking villain -- NotchUp

A couple of weeks ago many wrote about the mistakes of spock which made us call them the "evil spock" for the way they had you mass mail your friends by fooling you into thinking they were already users of Spock.

Securing home computer networks

Bruce Schneier has made a fuss by writing about how he leaves his wireless internet open. As a well regarded security expect, how can he do this. You'll see many arguments for and against in his posting. I'll expand on one of mine.

Part of Bruce's argument is one I express different. I sometimes say "Firewalls are a hoax." They are the wrong choice for security, but we sell them as a good choice. Oddly, however, this very fact does make them a valid choice. I will explain the contradiction.

Just when you thought it was safe to buy a blu-ray player

The last week saw some serious signs that Blu-Ray could win the high-def DVD war over HD-DVD. Many people have been waiting for somebody to win the war so that they don't end up buying a player and a video collection in the format that loses. (Strangely, the few players that supported both formats tended to cost much more than two individual players.)
