Sometimes you need thorough research to confirm what common sense tells you but ideology wants you to ignore.

Digital Rights Management (DRM) is a technological dream: technology which will control how and when and who views digital copyrighted content. For users it is a cumbersome nightmare which will prevent you from using the material in normal everyday work and play.

A UK researcher (Dr Akester) has confirmed this notion: out of desperation even normal people will start to circumvent the measures, creating the exact opposite of the desired outcome.

Conclusion (1): Although DRM has not impacted on many acts permitted by law, certain permitted acts are being adversely affected by the use of DRM.

The synposis is to be found over here.

RFID (Radio Frequency IDentification) is a technology which allows you to communicate wireless with a small chip/processor that (usually) has no battery of its own. The energy in radiowaves directed at the device is used to power the chip. In practice this means that the distance between a reader and a device must be relatively small (or that you can fry the chip when the radio power is too high).
These chips and devices are simple, passive and can be produced for very low costs.
The first applications were in logistics (tracking and tracing devices) . Nowadays they are used in many professional applications, such as ID-cards (OV-chip), medical environments and so on. All very professional and boring.

And now they have become available for personal use. In a very attractive design and a clever way of packaging called Mir:ror, designed and sold by a small company called Violet.  

What the Iphone was for mobile phones is the Mir:ror for RFID. It has become something my wife and children can understand, like and use. 

Magnificent, see the website and the video.

Reluctant

The European Commission has finally published its draft "Guidelines for the application of State Aid rules in relation to the rapid deployment of broadband networks" for consultation (pdf downloadable EC_NGA_guidelines_en.pdf). 

As always, there are 2 views and souls competing with each other within the EC. On one hand you have people who try to prevent terribly ineffective and expensive protectionists measures by states who pour money into badly run companies, on the other hand you have people who are fed up with the monopolistic attitude of (many) large telecom companies and want to get them moving in badly needed rollouts of next generation networks to all parts of the EU.
The dichotomy is visible in the draft guidelines. There are some openings (like definition of White, Grey and Black areas, ackowledgement that yesterdays broadband may be tomorrows narrowband and cannot be compared, acknowledgement of the roles backhaul and topology play in unbundling and open access) but they are "compensated" by restrictions and definitions.

The devil is the detail. Next Generation Networks (NGA's) are defined as:

a NGA network is further defined as involving: 
(i) laying fibre to existing street cabinets offering the
prospects of downstream bandwidths of a minimum of 40 Mbps and 15 Mbps
upstream (compared with today's downstream speeds of a maximum of 8 and 24
Mbps for ADSL and ADSL2+ access technologies, respectively); (ii) upgrading
current cable networks to deliver speeds up to and beyond 50 Mbps against the
previous maximum speed of 20 Mbps, using the new 'DOCSIS 3.0' cable modem
standard, or (iii) connecting newly built homes and offices with fibre connections
offering services up to 100 Mbps and beyond.44

Interesting: FttH to existing homes and offices is excluded in the definition? Some reality gap over there?  Docsis is mentioned as a specific technology without any upload spec, VDSL is specified. with upload? If you start to specify technology, why leave out the inherent capability of cable and fiber to support an RF overlay (for analog or DVB TV?). 
What happened to technology agnostic specifications? The worst mistakes arise from laymen trying to specifcy technology.

The most glaring "compensation" is the impossible burden of proof that is introduced. 

... for the purposes of assessing state aid for NGA networks, an area where such networks do not at present exist and where they are not likely to be built and be fully operational in the near future by private investors should be considered to be a "white NGA" area. In that regard, the term 'in the near future' should correspond to a period of [5] years.

The renowned Science philosopher Dr Karl Popper has introduced the concept of the falsification. It is usually impossible to proof the positive argument (one can go on forever supplying proof that the test is true), it is much easier to falsify a hypothesis : you need only one proof of the falsification (hypothesis is false) to proof the hypothesis is wrong.

The EC takes the opposite approach, creating an impossible burden of proof on governments where companies do not have to proof an intention to roll out to create a blockade.
If an operator claims a roll-out in the next 5 years (on paper) it blocks any initiative from a (local) government. If after 2-3 years "unforeseen" circumstances appear which "force the operator to delay investments" the cycle starts again: the government has to prove that the operator will not roll out in 5 years FROM THAT MOMENT ON, which the operator can easily claim on paper that he will do.

This is effectively a free (no obligation, no costs, no commitment) blocking trigger which can be used by any operator almost indefinitely to block any initiative from a municipality or government. Very lopsided. A enforceable burden/commitment of the operator to roll out if they want to excercise the blockade would have been more balanced.

What a difference with other bold and audacious initiatives such as the Singapore NGA investments, or the Australian NGA plan to force the roll out of a fiber network all over the country.

Pretty soon laptops will be replaced by what we now call netbooks: powerful (enough for everyday use), low weight, high connectivity, long batterylife and sleek design. 
And very versatile in unexpected situations (see the video).


Solar PC

|
The race for longer batterylife in netbooks creates technology which can have wide ranging effects on the energy requirements for home computing. Just look at the specifications of the first PC which uses the Atom chip from Intel. 
300px-Hands.jpg

Only 8 watts with the CPU running at full power. With a CPU running at 1,6 Ghz and a hardware video accelerator supporting 1080p full HD it is a machine adequate for most tasks.

Lets assume you want to run this PC on solar power only. All you need are some batteries at 12 V and a solar charger....
briefcase solar generator.jpg
such as this one available through Amazon for 70 USD, rated at max 30 Watts.

Crossover

|
Instead of packaging more power into a computer we are experiencing a shift in developments towards mobility and ubiquitous computing. Lower power consumption, less weight, more connectivity, like in netbooks. Approaching the same spot from another angle are the smartphones. So new entrants see a window of opportunity for the key component: the operating system. Why leave everything to MS or Apple or Symbian? 
Google has introduced Android for smartphones which already has been ported to netbooks by some enthousiasts. And Intel steps in with Moblin. Officially for netbooks, but when you see the beta movie you can'y help thinking it would make a great OS for a smartphone.
And again: a Linux derivative...

I would be very worried if my name was Microsoft.

Mobile traffic jams (2)

|
We have written earlier about the need to upgrade the backhaul network which connects the approx. 25,000 antenna-towers in the Netherlands with the Internet.

One potential solution apparently is not viable: connect the antenna-towers with the existing cable-networks. 
Cable networks cover a large part of the Netherlands and overlap with the copper networks used for telephony, connect every home as well. The speeds advertised by the cable networks (such as UPC Fibre Power 120 Mpbs/10 Mbps) appear to be at least 5 times better than the SDSL and microwave connections which are used now. Upgrading to cable connections must be a lot cheaper than digging new fiber all the way to central exchanges.
And yet this is apparently not an option, nobody uses a cable connection for backhaul.

The only logical conclusion is that the shared architecture of cable networks and the already limited backhaul capabilities of these networks prohibit any garantuee of service levels. 
Which says something about the inherent limitations of these networks versus the advertised claims.

( My sources tell me that the mobile operators have sent their RFI's for upgrades to the cable networks, but the response was "yes we can if we dig and lay fiber all the way").

'Action through thought'

Controlling computers with your mind......hmmm.

The French are trying to tackle the problem, with promising results. 



Free or Fantastic

|
Governments have resorted to spending hundreds of billions in a bid to recover the economy. The spending frenzy has attracted a lot of industries that were under pressure anyway: why not get a bailout as well?
One of the industries under attack are newspapers. What is the business model to survive in the Internet age where news is no longer the exclusive domain of journalists?

The wrong answer is proposed in the WaPo by 2 lawyers. Create crazy laws like:

Change copyright law so that "the taking of entire Web pages by search engines, which is what powers their search functions, is not fair use but infringement." 

One commenter  describes their proposal as the "Dinosaur Recovery Act". 
But if they have the wrong answer, what is the right answer? 
Recently the former chairman of Nokia has given a speech to newspaper companies about their future. His message was simple: "Become Free or Fantastic". 
I agree. I will pay for extra information, good background research and so on, not for fleeting "news". But why do I have to pay for a large organization, overhead and so on, and for journalists that do not add value for me? 

I see a future where we pay individual journalists/bloggers (or maybe a small group of journalists) directly for their contributions. Does it add up? Lets assume a contribution of one (1) euro per month per subscriber. With 10.000 subscribers or more you are in business.

How could you introduce such a model and garantuee payments? Use a modified form of RSS and create a billing/aggregation intermediary role (the new "newspaper"?). Lets call the intermediary "Newspal". Independent journalists/bloggers establish a relationship with Newspal and define their business model/prices. Newspal publishes through open RSS excerpts of their work  As a reader you subscribe at Newspal for the journalists/bloggers you value, Newspal feeds you through a special RSS feed their pieces. Newspal pays the journalists according to the amount and price of the subscriptions. 

Simple.
Lets start this company. 



Jeffersons Warning and Macaulays Evil

|
publicdomaincover1.jpg
"The Public Domain"  by James Boyle is undoubtedly one of the best introductions to the origins, concepts and dangers of copyright law you can find. Not only available in print but also online.

One of the gems in his book is what great minds in the past have said and written about copyright, such as Thomas Jefferson. (see this page).

"Considering the exclusive right to invention as given not of natural right, but for the benefit of society, I know well the difficulty of drawing a line between the things which are worth to the public the embarrassment of an exclusive patent, and those which are not."

The Jefferson Warning boils down to 5 cautions.
• First, the stuff we cover with intellectual property rights has certain vital differences from the stuff we cover with tangible property rights. Partly because of those differences, Jefferson, like most of his successors in the United States, does not see intellectual property as a claim of natural right based on expended labor. Instead it is a temporary state-created monopoly given to encourage further innovation.
• Second, there is no "entitlement" to have an intellectual property right. Such rights may or may not be given as a matter of social "will and convenience" without "claim or complaint from any body."
• Third, intellectual property rights are not and should not be permanent; in fact they should be tightly limited in time and should not last a day longer than necessary to encourage the innovation in the first place.
• Fourth, a linked point, they have considerable monopolistic dangers--they may well produce more "embarrassment than advantage." In fact, since intellectual property rights potentially restrain the benevolent tendency of "ideas . . . [to] freely spread from one to another over the globe, for the moral and mutual instruction of man," they may in some cases actually hinder rather than encourage innovation.
• Fifth, deciding whether to have an intellectual property system is only the first choice in a long series.13 Even if one believes that intellectual property is a good idea, which I firmly do, one will still have the hard job of saying which types of innovation or information are "worth to the public the embarrassment" of an exclusive right, and of drawing the limits of that right.

Thomas Macaulay repeated this position in England 30 years later:

"It is good that authors should be remunerated; and the least exceptionable way of remunerating them is by a monopoly. Yet monopoly is an evil. For the sake of the good we must submit to the evil; but the evil ought not to last a day longer than is necessary for the purpose of securing the good."

I wonder if any politician who is discussing copyright extensions to 99 years or "three strikes you are out" proposals has ever bothered to read what great minds have thought and said...

It has been all over the news: the French government has passed a law (HADOPI) that gives an agency the power to cut off your Internet access if you download illegal content, without a court order or the intervention of a judge.

One of the legacies of the Enlightment is the idea that you can isolate object and subject, that you can decompose reality into its parts (deterministic) and recompose it again, that you can change one parameter while everything else stays constant. This fallacy is widespread and leads to "unintended consequences": big surprises.

As most likely in this case. 
The detection methods and identification methods of illegal downloaders rely on IP-adresses and checking packets. The "digital natives" are very aware of ways to bypass these methods (such as widely available VPN services that for instance bypass geographical lockouts for services like Hulu. Usenet is quite popular as well). 
The geeks can go one step further and spoof IP-adresses, taking over someone elses identity (if you rely on an IP-adress). So what would be more satisfying than to:
- get hold of the IP-adress of a celebrity, minister, judge who is a supporter of HADOPI and is a naieve "digital tourist"
- get a bot to spoof this adress and start to download continuously illegal content
- expose the illegal downloads in the press and ask the agency to shut down the celebrity or politician

How long will it take before we see the first politicians trying to explain in public that they did not download as recorded?

Why wifi does not work

|
Wifi often does not work like you would like it to ( see Wifi War ). 

Ofcom (the UK telecom regulator) has commissioned an interesting report (wfiutilisation.pdf) to find out why. 

What they discovered is that while Wi-Fi users blame nearby networks for slowing down their connectivity, in reality the problem is people watching retransmitted TV in the bedroom while listening to their offspring sleeping, and there's not a lot the regulator can do about it.

Outside central London that is: in the middle of The Smoke there really are too many networks, with resends, beacons and housekeeping filling 90 per cent of the data frames sent over Wi-Fi. This leaves only 10 per cent for users' data. In fact, the study found that operating overheads for wireless Ethernet were much higher than anticipated, except in Bournemouth for some reason: down on the south coast 44 per cent of frames contain user data.

Mobile traffic jams

|
We all have become used to mobile Internet. When EDGE came along the access bandwidth speeds became acceptable. UMTS and HSDPA have been deployed and LTE is on the horizon, promising even more speed. 
But can these speeds be supported in real life? HDSPA is advertised with a download speed of max 3.6 Mbps (as my modem tells me at this moment) but I have never experienced anything close.

The reason might be the limitations of the backhaul network. There are approximately 25.000 antenna locations in the Netherlands. All traffic (voice and data) generated by mobile users connected to any particular antenna must be transported from the antenna location to and from the Internet (for data). In practice: to Amsterdam to locations near the AMSIX. 
Only a few of these locations have a fiber based backhaul. Most of them have either a SDSL connection (2/2 Mbps) or a microwave uplink of 2/2 Mbps. For ALL data of ALL users. In some cases a lot of these microwave uplinks are concentrated into a 34 Mbps uplink to the next concentration level,  where a fiber takes over.

It is clear that the advertised speeds can never be met without a serious upgrade of the backhaul network. Some operaters have started to do so, others are hesitating and asking for quotations. Some are hoping that the FttH-rollout will be quick enough so they can use this infrastructure for the upgrade: much and much cheaper than dedicated digging (many thousands of euros per mast).
One thing is sure: it will take time. In the meantime: don't be surprised when you have some traffic jams in your mobile internet.

Unbundling Japanese style

|
One of the benefits of participating in an emailgroup on next generation networks (Cook's List) is that you meet interesting people. This morning Tim Poulus and myself had a great chat with Adam Peake, Associate Professor at the International University of Japan, exchanging information on the developments in Japan and the Netherlands.

Japan is the frontrunner in deploying fiber, there are more fiber connections than VDSL connections (the latter are even dropping in numbers). The plan is to have very high speed broadband everywhere in a couple of years, aka the ubiquitous deployment of fiber-to-the-home. So already the strategic process has been started: what's next? How can Japan leverage the infrastucture to develop new skills and exportable services/products? Already products like TV's all have an Ethernet RJ-45 connector, and are specified for a given minimal bandwidth.

Fiber is deployed by several companies. NTT is by far the biggest (over 75%), but some utility companies have done the same. NTT is continuing deployment, the utility companies seem to have slowed down or even sold their networks. They are competing where their footprint overlaps, but that happens rarely, and only in bigger cities. (Cable networks are fast (Docsis 3.0), cheap and seen as reliable, but they have a minor footprint and do not expand)
NTT is the only one expanding outside the main cities, interestingly enough often in cooperation with districts and municipalities. 

The architecture of the fiber network is shared,  a PON-network. (a feeder fiber is distributed near the homes by optical splitters into individual fibers, the electronics do a time-division-multiplex to give each user his own Internet.)

To my surprise a different operator can rent fibers from NTT, for 5000 Yen (Eur 38) per month per 8 users.  Why per 8? The PON network is first split in 4 fibers, afterwards each fiber again in 8, giving a total of (industry standard) 1:32 split. This way a relatively low level of granularity is achieved, allowing for a sort of unbundling Japanese style.

In reality operators compete for buildings, for multidwelling units. As a building you choose for an operator. In advertisements for apartments it is normal that the seller specifices which operator supplies the Internet connection, next to other services that are supplied.

I wonder how long it will take before we see in real-estate ads in the Netherlands "fiber connected"....

I love simple and clever solutions to seemingly difficult problems. Like how to scan a book and transform the image to digital text..
Traditional scanners require flat pages pressed to a transparant plate, but that is impossible with a book without damaging it. It is also slow and time consuming to press pages against a plate, scan them, remove the book from the plate, flip a page and repeat the process.
If you open and handle the book and the pages as if you are reading it yourself  it is easy and fast. You can take a picture with a camera of a page, but the image is severely distorted so the error-rate of OCR programs skyrockets. 

Google has come up with the solution. Ingenious: Occam's Razor applied to an engineering problem.

Google_figure_3.jpg
 
An extra infrared camera-set  creates a 3-D image of the curved bookpages. This information is used to correct the image of the bookpages for spatial distortions. And voila, the OCR programs can work like advertised.
