Net Neutrality and the Berner Convention

|

The Berner Convention (originally 1886, latest revision 1979) is the mother of international copyright law.  An international treaty  "For the Protection of Literary and Artistic Works". The treaty automatically assigns copyright to an author for his/hers lifetime plus 50 years. The right is a monopoly and extends to almost any form of publication. As the revision date shows it does make some allowances for broadcasting audio and TV (wireline/cable, terrestrial or satellite) but not explicitly for the Internet, as it was not yet invented in 1979.  

In practice a body of (case) law has been formed  (and still is being formed: for example the Cablevision DVR-on-the-net in the USA) to accommodate both the broadcasting and the Internet environment.

There are some interesting differences: a cable company delivering linear analog or digital TV (DVB or some other encoding method) is seen as the publisher of copyrighted material and has to get permission from the authors (meaning: has to pay them). The same applies for walled garden IP-TV offerings by telco's. But if the same customer uses the broadband connection of the same cable company or telco and views a video over the Internet, the law does not regard these companies as the publisher. The owner of the website where one can find the video is seen as the publisher of copyrighted material and has to get permission of the authors.

Why? Copyright-lawyers have explained that the difference is the concept of "Common Carriage". The Internet access provider has no relationship with and does not interfere with the content of the messages which he transports. Message and content agnostic. In that case (and only in that case) the company which transports content to and from your home is not held responsible and therefore is not regarded as a publisher of copyrighted material.

Enter Network Neutrality. Wouldn't it be a very nice twist if we use the above mentioned definition, the existing body of (case) law and its consequences as the basis for Net Neutrality? The threat would be: if you mess around with IP-traffic you are in danger of losing the "Common Carriage" status, you risk to be regarded as a publisher of copyrighted material with all consequences attached to that status. You would become responsible and liable if you mess with traffic.

As I am not a lawyer I might have missed something, it might not cover everything (VOIP traffic for instance), but at the least it would cover a large part of the Internet. The beauty with this approach is that nobody will try to change existing copyright case law. 

Maybe......

Jamiton

|
A "soliton" is a self-reinforcing solitary wave (a wave packet or pulse) that maintains its shape while it travels at constant speed (Wikipedia). Researchers at MIT have discovered that the mathematics describing traffic flow under high densities are quite similar to the fluid dynamics equations that describe solitons. 
They have coined the term "jamiton" (jam-soliton) to describe the well known effect that in dense traffic a traffic jam appears for no apparent reason. 

Hopefully this breakthrough will lead to knowledge how to prevent these traffic jams.

The future of TV

|
Classical music is one of the most demanding performances for audiovisual encoding and decoding. Wide dynamic range, listeners with trained ears, many benchmarks. The highest barrier for using the Internet to show performances.

Medici.tv is a French company that shows how far we have come with recording and playing back live shows of classical music. Open the website, click the "high" button in the upper right hand corner, get full screen and open up your speakers or headphones.
Enjoy and be amazed.

As our desire to get hyperconnected is insatiable, airlines (at least in the USA) are responding fast.  

USD 12.95 for good wifi on a 3 hour flight is worth it. And when its good enough to support a video chat (see this video) I will not complain. When will we get this in Europe?


While rather naieve politicians in the Netherlands blindly follow propaganda of the media industry about file-sharing, while the UK is no different, some researchers from Harvard Univiversity have tackled the real hard question: does file-sharing stifle content creation?
As they rightly state, copyright laws have never been designed to protect an industry, their purpose is to foster and reward creativity for the benefit of us all.

Ars Technica has an excellent analysis of the report (work in progress).

The authors construct a bit of a causal chain between file sharing and the intent of copyright law to foster creative works. First, you'd need to know that file sharing was harming music sales, and that the music industry wasn't finding alternative ways of generating income. Then you'd need to show that the loss of income provided a disincentive to musical creativity.

The authors show that the first two arguments do not hold: the loss of some revenue of direct sales is offsett by higher fees for concert tickets.

If the first two links in the chain are tenuous, the last one pretty much gets demolished. There's essentially no indication that the more challenging economics are slowing down creative content production. In the five years prior to 2007, film production is up 30 percent, album releases have doubled, and book releases are up by two-thirds.

Although the paper could be improved and is not yet been scrutinized by the community, it is al least a solid evidence based approach to the issue. Something which cannot be said for most others.

Two is not enough

|
One of the mantra's of (telecom) competition authorities is that competition will lower prices and improve services.
Some economists (like the chief of the CPB (Bureau for Economic Policy Analysis) Coen Teulings) believe that "2 is enough" to create adequate competition, relating to the reality that cable and the phonelines (DSL) used to be the only options for the last mile to your home. Another option (a 3rd operator with fiber for instance) would not be needed to have a real market, therefore the market was not distorted, therefore there was no justification for any intervention.

GigaOM reports how the latest Pew Internet & American Life Project poll on U.S. broadband trends shows that this assumption turns out to be false.

The other interesting observation is that DSL is still big but on its way out: cable and fiber will become dominant, reducing (in the long run) the number of options again. When fiber fulfills its promise and starts to leave cable behind the number of options will be reduced again.

A strong case for structural separation of the physical network and unbundling of fiber loops.

The Cost of Clean Energy

|
The proverb "where the rubber meets the road" points to the reality check one has to do with any concept: what will be the cost? 

Altenergystocks has an interesting post on this subject: the available numbers (USA), the sensitivity for interest and depreciation, and a graphical comparison of the integral cost per MWh. Food for thought.

Is it a car, is it a motorcycle? Nowadays you see more and more hybrid designs, with 3 and 4 wheels. Like the Piaggio MP3, the Carver, the T-rex, the Aptera and many others (see a list of 3 wheelers over here).

You have to hand it to the French to come up with yet another variation. 
A 4 wheeled, 1 person (electric) vehicle which tilts in corners. 
Nice design, very small which is great for commuting in cities. It will keep you safe and dry which is another advantage.
Range up to 150 km with a 10 KWh battery, speed up to 130 kph. Not bad.

Only the price: 24,500 euros is way too much. The lower fuel bill (approx 1200 euro per year) will not compensate for the higher investment. Too bad.

Smart use of technology

|
pulse_paper.jpg
I like really smart implementations of technology.
 
Marjolein just demonstrated the Pulse smartpen from Livescribe to us. A pen with an integrated voice recorder. 
The really clever bit is the combination of the camera in the tip and the special micro-dotted paper you write on.
The dotstructure in a given location is unique so the camera can tag voice recordings to your writing and the image of your writing.. See this movie over here.  

So you sit in a meeting, take notes and record at the same time. Afterwards you can read your notes on a PC, tap a word and hear the corresponding voice recording.

Clever.

How traffic jams are created out of thin air

The power of connectivity

It is amazing to follow the smart use of Twitter and its API's, Facebook en Flickr by protesting Iranians today. Bypassing the blockade of professionals journalists, using the tools the Chinese protesters did not have 10 years ago.

See for instance:
- pictures of todays rally (large masses out there) and killings
- twitterfeed persiankiwi , Iranriggedelect ,  or search for #iranelection

Twide a year the sun sets in a spectacular way in Manhattan: almost a third millenium Stonehenge. Neil deGrasse Tyson, director of the Hayden Planetarium in New York, identified the cosmic event over a decade ago and coined it Manhattanhenge. 

Lies, damn lies and productivity statistics

|
One of my favourite blogs is Evolving Excellence, dedicated to Lean Thinking in production and services. Outspoken, opiniated but well researched, practical.
Bill Waddell , one of their prominent bloggers referred in one of his blogs to a stunning fact.

The productivity statistics as published by the Bureau of Labor Statistics of the USA are fundamentally flawed and overrate the actual productivity.


"Conceptually, the impact of offshoring is more pronounced in manufacturing measures than in business sector measures, provided the domestic manufacturer is purchasing the offshored goods or services as inputs. ... If a domestic computer manufacturer switches from domestic to foreign suppliers of intermediate parts such as memory chips or call center services, real manufacturing sectoral output is unchanged because the real value of the computer is unchanged. Because U.S. jobs are lost (all other things unchanged), labor productivity will rise. If the U.S. manufacturer switches most of its production to off-shore facilities, labor productivity might rise substantially." 

As Bill says " In other words, if the furniture factory lays off all of the people who make legs, seats and backs, and buys those parts from China, but keeps the few people who do the final chair assembly, the jobs lost to China are called "productivity"."

I remember all the economists and journalists praising the USA for its high productivity growth, compared to the EU. The better system...
Apparently at least a part of it was a (convenient) damn lie, keeping the foreign investment dollars coming to the USA.
 
A recent article in The New Scientist touts a catchy header: "A plane can be worse for the climate than a train". The header will most likely be found very soon in many newspapers and blogs, because hardly anyone will bother to read the original, thorough and comprehensive study. 

The conclusion of the study, if you read carefully and study the graphs, is the opposite. Trains are almost always better than airplanes and have a lot of room for improvement (renewable electricity, less concrete while constructing railways and stations).

This is not journalism, it is manipulation.

It's kind of ugly, but still.....A build-it-yourself plug-in hybrid vehicle, capable of doing (claimed) 100 km on 2 litre of diesel.  You can purchase all the plans and CAD designs for a few hundred dollars and build it in your garage.
Could anyone interest a European designer in creating a more continental and sophisticated body? Please?

Telepresence as killer app

|
NEC_CRV_43_1.jpg


Some years ago I supervised a test of a sophisticated videoconferencing solution. The purpose of the test was to see what use a wide range of people (young, old, background) would have of a smooth and natural video-communication solution. 
One of the surprises was the reaction of elderly (less mobile) citizens: they immediately saw it as a method to keep their social life active, to compensate for their reduced mobility. And one-on-one video-calling? Too limited, they would like to be able to play a game of bridge as a social occasion (not a game). We recognized immediately that if you could create that telepresence experience the number of applications would be virtually unlimited, bith professionally and socially. It would change our way of life and work.
When you start to consider the technological challenges implicit in this seemingly simple request it is clear we have some way to go, starting with fiber networks to the home. 

Visualization is another challenge but progress is being made.
Like this amazing NEC 43 inch curved monitor with 2880x900 pixels, available on pre-order now for less than 8000 USD. A big step forward. Imagine it with 3D technology and we would be getting close.




Negative emissions

|
One of the taskforces of the IEA (International Energy Agency) is taskforce 33: Thermal Gasification of Biomass, sharing the knowhow on how to build large scale biomass gasification factories. Gasification has the potential to generate Synthetic Natural Gas (SNG) from biomass: it even makes sense to import biomass.

Recently it has become clear to me that there is another big advantage to this process.
Thermal gasification produces enough heat to keep the gasification running and some more. At the end of the process you have invested 30 % of the raw energy input (wood) in the gasification and the transformation of syngas to 2 seperated streams of gases: SNG and pure CO2. When you store the CO2 underground the nett result is NEGATIVE CO2 emissions: a CO2 sink! As far as I know the only process with a negative CO2 impact.

Even more reason to invest money and energy in this process.




Pressure

One obvious method to reduce the fuel consumption of internal combustion engines is to reduce the energy losses.
Losses like moving large pistons, pumping a minimal amount of air inside the cilinder: which is just the average status if a large engine is delevering a low amount of power (idling, city use, low speeds).

The trend in all cars is to reduce the cilinder size and increase the amount of air you can push inside the engine with a turbo so you can get the same amount of maximum power. It reduces the fuel consumption, but with a price: the bigger the turbo the bigger the delay in response. The dreaded "turbo-lag" translates to a negative driving experience and potentially unsafe situations.

Researchers in Switzerland experiment with a novel solution to the problem. If the engine can function as an air pump when you are braking you can store air in a pressure tank. If you want to accelerate again and the turbo is lagging, pressurized air is used to fill the gap.
Smart engineering.
However: you wonder if this added complexity will ever be able to compete with serial hybrids where combustion engines mainly function as generators: fundamentally no problem with a turbo-lag.
