Mijn advies aan Min. EZ over breedband buitengebied

RBI Fiber-to-the-Farm

Fiber-to-the-Farm (FttF)

1. Weergave van mijn vertoonde sheets : Freq beleid Tafel 2, 4 feb. prof van Till (1)   op 4 April 2016 te Den Haag

2. Korte samenvatting:

” Om een discussie over breedband in buitengebieden te starten, geeft Dhr. Jaap van Till een presentatie. Samengevat concludeert hij dat 228.000 adressen in Nederland geen toegang tot snel internet (via DSL, kabel of glas) hebben. Het aanleggen van glasvezel (fibre-to-the-home) + een eigen small cell (bijv. in 700 MHz) op woning, bedrijf of schuur; is de enige toekomstvaste oplossing.

3. Mijn conclusie:

Naar aanleiding van mijn onderzoek in de maanden december en januari 2016; en de
discussie na afloop van mijn korte inleidende presentatie gisteren 4 februari, adviseer ik het Ministerie om als beleidslijn m.b.t. breedband netwerktoegang in de buitengebieden,
voor de genoemde 223.000 (post) adressen, die thans geen coax aansluiting
en geen twisted pair koperdraden aansluiting met > 30 Mbps hebben,
te kiezen voor het aanmoedigen van investeringen in:
– vaste aansluitingen met behulp van optische fiber kabels tot in de
   woning/boerderij/landhuis/camping/bedrijfsvestiging/school/etc.
PLUS
– draadloze verbindingen vanuit/op bovengenoemde vestigingen met behulp van
  of: Wi-Fi + (verbeterde versies van huidige Wi-Fi)
  of: zelf opgestelde 4G small cell apparatuur met sub licentie van een operator
  of: zelf opgestelde small cell apparatuur met licentie van AT in 700 MHz
 .
ten behoeve van gebruik binnen de woning/stallen/schuren/gebouw/laboratorium/ buiten op het eigen veld; op camping. Met name voor bewegend cq nomadisch gebruik.
Reden is dat dergelijke combinaties toekomstbestendig zijn de komende tien jaar, qua
benodigde toenemende datacommunicatiebehoefte, thans geschat op verdubbeling
elke 9 maanden. En qua kosten in Capex + Opex over een langere periode veel goedkoper
dan volledig draadloos of via VDSL+ vectoring.

Can computers be trusted ? Probably not. Cartoon # 3 of 3

myth3

Found on our attic, partly eaten away by bookworms (!!?): three drawings called “Computer Myths Explained“, of a series of 8, which I bought from Creative Computing in 1979, by the famous Monte Wolverton, see Wikipedia https://en.wikipedia.org/wiki/Monte_Wolverton and his website: http://www.wolvertoon.com/

This is no.3 : Myth = Computers can’t be trusted and when finally imbued with higher reasoning powers they will do evil, treacherous things !

That is what Wolverton wrote in 1979 below this cartoon. It reflects fears for computers that are still in the minds of many people. And…. they probably are right. Computers are power tools programmed to do specific tasks and now able to do many things that only humans could and faster. Internet of Things (IoT) , AI built after how we now think that brain functions work.

IMHO we should not be too nervous about “robots” because their computer power is still not exceeding that of a fly. What we should closely watch is how networks of computers are interconnected to process information and make decisions, ike for example the distributed computer systems that buy and sell stocks. Even quants can not see through how those systems have been constructed and even they wonder if that financial system is stable any more, or can be made stable. Maybe a redesign should be started, which includes the decentral blockchain ledger system to reassign trust between parties that transact. “Have a nice day !!!”.

Views on PC usefulness in 1979, no 2 of 3

Myth2

Found on our attic, partly eaten away by bookworms (!!?): three drawings called “Computer Myths Explained“, of a series of 8, I bought from Creative Computing in 1979, by the famous Monte Wolverton, see Wikipediahttps://en.wikipedia.org/wiki/Monte_Wolverton and his website: http://www.wolvertoon.com/

This is no.2 : Myth = Home Computers are useless and boring

” If Home Computers (now called PCs, laptops, tablets and smartphones) Really cant’t do Practical things, like washing the dishes, vacuuming the carpets and doing the laundry, then they are poor investment for the average person, except for maybe an occasional game of pong, which will quickly become a bore. ”

Things in the home have indeed not become easiers with pc’s  but now most of our family members uses several computers so intensive that it looks as if they are addicted. And the number of users is huge. For instance take a look at the “Facebook Community”, which has more inhabitants than the Republic of China.

Facebook community

Key is that the computers are interconnected by ethernet and/or Wi-Fi and that they are connected on the internet by ADSL, Cablemodems or FttH. And that the users have somthing to talk about or exchange. Communication and group membership, and collaboration , see my 4 network effects blog, are the driving force for the global computer networks for billions of people.

Views on IoT in 1979, no. 1 of 3

Myth 1

Found on our attic, partly eaten away by bookworms (!!?): three drawings called “Computer Myths Explained“, of a series of 8, I bought from Creative Computing in 1979, by the famous Monte Wolverton, see Wikipedia https://en.wikipedia.org/wiki/Monte_Wolverton and his website: http://www.wolvertoon.com/

This is no.1 : Myth = Home Computer Housekeeper

” Home Computers free you from the household chores by doing home cleaning, change diapers, clean dust, do the dishes, etc. etc. ”

Things in the home will at last start to interconnect in 2016 and will cooperate (with us too, I hope, but it will still take a while to be useful. We need a neutral ‘Inhouse Internet Infrastructure’ first. That means NOT verticaly integrated from suppier/app down to links. That would lock us in and will be obsolete in no time. My guess is that communication infrastructure will be built by using combinations of indoor Wi-Fi and electricity power cables with at least 2 plastic optical fibers in it, to hauled through the present inhouse yellow plastic pipes. Indoor Ti-Fi light links (my invention) will appear later.

Do Support “TransTribal Collaboration” #TransTco

Screen Shot 2016-01-20 at 09.12.05

This is urgent. We have to recognize and support #Btwieners who can bridge the fences and borders between groups of people by connecting able and creative specialists who can solve problems together by contributing proven knowhow from different perspectives and backgrounds.

  1. What is the problem: We have to find a remedy against the recently floods of xenophobia and fear of foreigners and people with other skin colours,  cultures and religions.

There is a recent flood of protests against inflow and reception of migrants from outside the EU. In a number of countries, like France, England, Sweden, Russia and Germany, at the same time large parts of society are voting and joining political groups protesting against immigrants and asylum seekers. These groups insist on closing borders with vocal xenophobia and talk about ‘authonomy’ and ‘sovereignty’ looking inwards, which is ridiculous since in the present world business, networks and social ties are getting more and more interconnected and interdependent. 

  • Being ‘stand alone’ & living on mental islands does not exist any more. Everything and everybody is connected. 

The underlying fear of those groups is that they are uncertain about their jobs and future. They feel threathened by the outside world and seek the comfort of bygone days and certainties of cultural identities, political ideologies or religious systems that feel good and seem to have an explanation for all evils. Result is extremism, ethnic cleansing , intolerance and violence against the outsiders to show you are member of the clan or tribe.

Especially  the recently converted sect members are real blind dog zealots who act violent in their quest to find connection to the ‘pure’ core of the tribe. And they are active to convert others to their ‘idea system’. Which is applauded by the hierarchical leaders, from maffiose bosses to dictators, who like to have a big following by attacking others hope to show their potency by fights about hegemony and POWER. This is destructive and it kills lives. Closing up within your own tribe or nation state and hating or even shooting, bombing and killing (IS) all outsiders is not a solution. It even can turn out to to be suicidal since the outsiders can have the same violent sentiments about YOU. 

2. What can we do about this downward spiral of hatred and violence? Not by destroying, shooting by militia / police persons or by droning tribesmen and their families. The solution IMHO is to have a  better and more constructive idea: openly interconnecting people from different tribes and backgrounds. The exact opposite from the ever more isolated tribes. No this is not a soft idea from vague ethical idealism. It is done right now by young people all over the world already. My generation unfortunately, consisting of hateful old men have difficulty with that, afraid as they are to lose power, authority and influence. 

Sure, tribes are no longer geographical bounded, since the internet makes distances less relevant, although the core of many of the most hateful tribes members are the old who have never left their village and consider those on the other side of the mountains, or other cities as sworn hostile and mortal enemies, having raided them for ages. No for instance members of the Ajax football supporters association are now located everywhere in The Netherlands instead of only in Amsterdam. But still the Ajax, ADO, PSV and Feyenoord hooligan supporters fight each other violently, and even take their sons and daughters to the cellphone organized fights.

And that is peculiar since their star teams consist rather obviously of the best professional soccer players that club money can buy. That is exactly what I see and propose to boost.

Young urban professionals, creatives and software whizz kids know that to achieve results and create value and wealth they have to set up a team consisting of the proven best skilled contributors from different fields, WHATEVER THEIR TRIBAL background, haircolor, sexual/music/food preference or shoe size. As long as they can be trusted to deliver what contribution they have promised to deliver in time and if they are interested and committed to correlate, cooperate and learn from the other top skilled kids in the team and from responses P2P from outside: clients and from other fields of knowledge however remote and weird and crazy as long as it is relevant for the project of the team.

This is TransTribal Collaboration ( #TransTco ) in its purest form. Result is that I run into whizz kids born in Chile, raised in Geneva, with job histories in Shanghai, Arnhem, Oxford, Frankfort, Cairo and Madrid. The new class of Trans-Nationals !!. Are they loyal to big branded corporations or nation states? Not really. They are loyal to their respected collegues and they flock together in the big cities of Corridoria and beyond.

3. My advice is to scale this kind of interconnections up by several proactive policies.

a. Companies and institutions: Instruct your HR people to hire very skilled professionals with a very wide diversity to collaborate and cooperate in such able and fast learning teams. If they are successful such teams work as magnets for talent. Indeed their success can be rewarded by measuring the number of people who beg to be allowed to join the team.

b. Governments Indentify who are the informal super networkers  in society I have called ” #Btwieners “. Recognize, support them and offer them financial support too !! Who are such persons and what do they do? They are highly skilled in “networking” which means that they can refer somebody with a problem to a person who has the solution or knows somebody else they can recommend who can [1]. I have studied this activity and give short effective courses in it [2]. But Btwieners are a higher level of that function. These people are respected and TRUSTED IN MORE THAN ONE TRIBE. A kind of traveling and visiting Gandalfs. It is a rare but extremely valuable breed of people.  They are able to select specialists from a number of tribes who can join in project teams described in a. to solve problems or from their unique different perspective can contribute parts of solution that have been tried and tested in other tribes. This is what happened in the Near-East ages ago when sages from widely different origins met halfway the Silk Routes to combine and synergize their knowledge and knowhow. Much of our Western and eastern cultures can be traced back to the combinations made there. Interesting is the fact that most of nature and indeed even our own bodies and brains contain btwiener-like organisms that repair, reconstruct and stabilise complex living structures. Professor Peter Csermely has described them in his “Weak Link” book [3].

“TransTribal Collaboration” : Please DO IT. Make bridges across tribal fences and borders and let the best young people connect to eachother to work and create synergy. New synthecratic structures with P2P Weavelets will emerge [4].

List of My Gurus and NewSophers

guru foto

(updated 2016 January 11, 13, 21, 26, Feb. 1, 12, 13)

My personal list of Gurus consist of wonderful teachers and visionaries who continue to spread light and life-energy each day for me, and I hope for you too. I call them my NewSophers (= New Philosophers)

  1. They are the present day likes of: John the Baptist, Rumi, Kahlil Gibran, Pytagoras, Galileo, Giordano Bruno, Joan of Arc, Erasmus, Christiaan Huygens, Spinosa, Leonardo da Vinci, Hugo de Groot (Grotius), Voltaire, Euler, Edgar Allan Poe (he proposed the Evolution Theory before Darwin did), Nicola Tesla, Brouwer, Richard Feynman, Wolfgang Pauli, Gödel, James Grier Miller, Karl Popper, George Orwell, Aldous Huxley, Lynn Margoulis, Jane Jacobs, Benoit Mandelbrot, R. Buckminster Fuller, Clare W. Graves, Elinor Ostrom, Isaac Asimov, Douglass North and Aaron Swartz, Claude Shannon, Eshel Ben-Jacob, Paul Baran and Marvin Minsky. To name a few. They share at least one very important characteristic. They have seen the future very clearly and dare(d) to write and speak about it, despite the conflicts they ran/run into with the public and their shepherds, the controlaholic kings and priests of the power hierarchy who are not amused about what these visionary men and women say and write. They are the Prophets of Renaissance2. And sometimes scientists accused them of being unscientific quacks. Which is peculiar since it is the very task of scientists to propose innovative and outlier theories which others can then try to validate or refute.  No, these ‘shapers’ where and are not directly popular, since they could look ahead through the fog of the present and through the layers and layers of filters of prejudices and mutually confirmed expectations, see the following drawing:

Filters

The unfiltered visions these exceptional people can see was/is unwelcome, and therefore these they often kept their mouth shut and wrote their private notes and visions in code or mirror image writing, showing sometimes years or decades later that they had seen things right. You need patience to do that, I can tell you. And be very brave and audacious.

2.The following list is imperfect, unfinished and incomplete like real life. And they are presented her in no particular order or sequence. Please comment with names of those who should be on this list of NewSophs who can look over (technological and society/moral) horizons. Bien étonnés de ce trouver ensemble:

I.1 John Perry Barlow  T: @JPBarlow    W: article about the future of the state

This is my personal #NeoSophers Hall of Fame.  Yes,  these giants are often very stubborn, autistic and difficult to talk to. But they did and do amazing imaginative and relevant things, that earn them a place in history. And they have a huge advantage over the earlier Guru-Sophs: the are ALIVE and active NOW, so you can ask them questions or ….a personal mantra and just cheer them along. Let me hasten to express my gratitude to them for I have, whether they know this or not, been briefly standing on their philosophical shoulders to enjoy the view. Full of beauty into the future of the Second Enlightenment which is starting up all around us.

Solvay-Conference-1927-620x180-1

Would it be possible with some funding to get them to gather for a 2016 conference and group photo, just like that of the famous Solvay Conference in 1927 of all the then relevant theoretical physics thought leaders?  They refuted at that conference the previously prevalent notion that “all there was to know about Nature’s mechanisms was already known” :-) NOT !!

Shall we organize a Second Solvay Conference ???

#

What do these very diverse ladies and gentlemen have in common? First of all, none of them was numbed by the prevalent “common knowledge” anesthetic or educational thought control. In other words: none of these giants took the blue pill shown in The Matrix film. Each and every one of them developed a very personal breakthrough BELIEF SYSTEM *) that did drive them and us to do great things. And from that belief they spread a gospel that inspired and resonated in the beliefs of others. A belief that can cut through all those filters shown above. Interesting example was the gospel that Steve Jobs expressed at the introduction of the Apple Macintosh personal computer: his hope and belief was to prevent IBM to become the dominant big brother of all computer sales that would squash innovation. And he showed a provocative film to express that hope, showing a girl hurling a big hammer at big brother. I remember that this “1984 video” really moved me in 1984. At that moment I made Jobs’s belief system MY belief system. *) For more about “belief systems” giving people a WHY for their actions, see the brilliant TEDTalk of Simon Sinek.

Mac 1984

PS1. Yes I will try to also make a list of brave prophets that are 30 – 40 years old. Please help me find them. They deserve glory NOW. Sure, daring geniuses manifest themselves at even younger ages. And .. where kicked out of school because their intelligence and broad knowledge far exceeded those of the teacher and other kids. I still remember the panic in the eyes of my teacher when I asked him “How does a nuclear reactor work?”. I (10y) just had read it under A (for Atoomreactor -NL) in the Winkler-Prins encyclopedia, and was puzzled why he hadn’t just looked it up himself. Since then I knew that most people are frightened by new & unexpected knowledge and avoid & filter it, instead of difficult issues. 

PS2. For those who grumble that there is a lack of focus on my list, or that I should give clearly defined requirements whether or not somebody should be entered, I say NO. These Prophets are very diverse and have talents that are broad and trans-tribal && trans-subject. That is why they have exhibited helicopter view. Please start to read from those you did not hear of before!

PS3. I was critisised for including people who did things wrong and or have published nasty things they ran into. But that ladies and gentlemen is the very point of these prophets. They are not in the business of science of “Likes and Likely”. The world is full of Unlikely and Do Not Like. The media are shy or under instruction not to show those, like in the case of the Hauptbahnhof Koln @HBF KOLN, but the prophets do tell what they see coming. And we should thank them.

Is there Hunger in North-Korea? Possible actions.

Risk of hunger2

These countries are most at risk of

  1. The map shows the countries with a high risk of hunger (the Hunger Index, calculated by the World Economic Forum), from which the WEF has statistics, that is.

The full WEF article is at  Full URL: https://agenda.weforum.org/2015/12/these-countries-are-most-at-risk-of-hunger/?utm_content=buffer4e0eb&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer

For instance North Korea is known to have had very bad harvests for several years resulting in famine suffering and death for hundreds of thousands of people. Their government refuses to confirm anything about that reality for fear it might hurt the glorious image of their ruling elite.

They also refuse most help in the form of food shipments from South Korea or other countries.

2. Maybe the following inventions can help the Korean and other countries PEOPLE to grow their own food in villages and survive. And  according to my friends in Wageningen University, world famous for its agriculture research, food availability is not only a matter of production in an ecology, but also of distribution logistics, where ICT networks can help improve a lot !!

A. “Earthboxes“: Homegrown Vegetables Without A Garden.® 

See: http://earthbox.com/ The ultimate growing system: The EarthBox® gardening system! A great value—you name it, you can grow it! Poor soil conditions and small backyards are no match for this patented container gardening system, developed by commercial farmers. Proven in the lab and on the farm, you get “great results no matter what color your thumb is,” because this maintenance-free growing system controls soil conditions, eliminates guesswork, and more than doubles the yield of a conventional garden—with less fertilizer, less water, and virtually no effort. Just add plants, water, and sunlight for an easy garden that requires no digging, no weeding, and no guesswork! Grow tomatoes and other robust vegetables and aromatic herbs in any small space—a balcony, patio, or even rooftops! This revolutionary SIP (Sub-Irrigated Planter) is even ideal for urban garden settings since its compact size allows you to grow healthy, fresh—even organic!—food where it never grew before! Unlike other raised bed gardens and planters, the EarthBox® gardening system is self-watering, sustainable, easily moveable and portable, and can even be used to grow indoors. Now that’s one smart garden!

B. Aquaponics, double loop closed systems, very successfully developed for instance in Amsterdam for “urban farming”, see http://www.mediamatic.net/251284/en/aquaponics-at-mediamatic-fabriek

Aquaponics is a sustainable, recirculating ecosystem for food production made up of fish, microorganisms and vegetables. The fish feed the plants and the plants clean the water the fish swim in. The system is pretty fragile when you start out, and has to be monitored constantly. The water has to be tested for certain chemicals, for its pH-levels etc.. Small changes to the composition of the water can be deadly. As the ecosystem grows it gets stronger, until it cannot only sustain itself, but also protect itself from external influences. As of August 2012 we have built a number of aquaponic set-ups, including a 4-storey tower (1 fish tank, 3 plant containers). We are monitoring, adjusting, and keeping our fingers crossed that our fish and plants survive and prosper.

Aqua

The system

An aquaponic system consists of at least one fish tank and one plant container. In the plant container, plants are grown on a layer of expanded clay pebbles. These are bits of clay that are baked at a really high temperature, which means they are full of air and let through lots of oxygen – more than regular soil. This is good for the plant roots. After a while the roots, bacteria and worms (that live in the layer of clay pebbles) start to form a complex ecosystem. Fish are kept in another container. Water from this container is pumped into the layer of pebbles at regular intervals. The water feeds the plants. The bacteria and the plant roots work as a filter: they clean the water, which is then released back into the fish tank. We feed the fish with the gluttonous, fast-growing larvae of the black soldier fly (hermetia illucens) found near the neighborhood trash. Result: happy fish and organic plants.

Erik Cecil (<erik.cecil@  gmail.com> ) wrote to me: “Tilapia feed plants, breed like mad, mature in 8 months or so; you can also grow duckweed to feed tilapia, plants clean water – no discharge it’s a closed system.  10x protein and veg per acre.  Fish protein much more efficient because they live in zero gravity environment.    No fertilizer.  Use 10% of water.   Several companies making huge progress in this area.  I’m working with a company in Canada deploying commercial scale systems.  I run a little system at home off a 75 gallon tank – beautiful green peppers and strawberries so far.  Fish love it because the cycles also aerate the water.  You can put red wiggler worms in the grow beds to eat the dead plant roots etc.  it is incredible how efficient the systems can be.  I have some data somewhere and will share with any interested”.

Farm from a box

D. Another upcoming variant are big concrete circulating ponds with algae, fed with pig poop. The grown algae (full of Omega-3 oils, ((that is where fish get their O-3))) are then fed to pigs which thrive on it.

E. Water purification to get safe water for drinking and cooking is also something which can be supported bottom up : see https://www.kiva.org/partners/263 using the Nasava Water Filters, very successful in Indonesia.

F. General remark about bottom-up food production

This is not my field of knowledge but these 3 idea’s may set you on your own journey of exploration and experimentation in the fields that give fruitful results for the hungry and you !!!
