The Emergence Of The Connected City


Glen Martin at Forbes: “If the modern city is a symbol for randomness — even chaos — the city of the near future is shaping up along opposite metaphorical lines. The urban environment is evolving rapidly, and a model is emerging that is more efficient, more functional, more — connected, in a word.
This will affect how we work, commute, and spend our leisure time. It may well influence how we relate to one another, and how we think about the world. Certainly, our lives will be augmented: better public transportation systems, quicker responses from police and fire services, more efficient energy consumption. But there could also be dystopian impacts: dwindling privacy and imperiled personal data. We could even lose some of the ferment that makes large cities such compelling places to live; chaos is stressful, but it can also be stimulating.
It will come as no surprise that converging digital technologies are driving cities toward connectedness. When conjoined, ISM band transmitters, sensors, and smart phone apps form networks that can make cities pretty darn smart — and maybe more hygienic. This latter possibility, at least, is proposed by Samrat Saha of the DCI Marketing Group in Milwaukee. Saha suggests “crowdsourcing” municipal trash pick-up via BLE modules, proximity sensors and custom mobile device apps.
“My idea is a bit tongue in cheek, but I think it shows how we can gain real efficiencies in urban settings by gathering information and relaying it via the Cloud,” Saha says. “First, you deploy sensors in garbage cans. Each can provides a rough estimate of its fill level and communicates that to a BLE 112 Module.”
As pedestrians who have downloaded custom “garbage can” apps on their BLE-capable iPhone or Android devices pass by, continues Saha, the information is collected from the module and relayed to a Cloud-hosted service for action — garbage pick-up for brimming cans, in other words. The process will also allow planners to optimize trash can placement, redeploying receptacles from areas where need is minimal to more garbage-rich environs….
Garbage can connectivity has larger implications than just, well, garbage. Brett Goldstein, the former Chief Data and Information Officer for the City of Chicago and a current lecturer at the University of Chicago, says city officials found clear patterns between damaged or missing garbage cans and rat problems.
“We found areas that showed an abnormal increase in missing or broken receptacles started getting rat outbreaks around seven days later,” Goldstein said. “That’s very valuable information. If you have sensors on enough garbage cans, you could get a temporal leading edge, allowing a response before there’s a problem. In urban planning, you want to emphasize prevention, not reaction.”
Such Cloud-based app-centric systems aren’t suited only for trash receptacles, of course. Companies such as Johnson Controls are now marketing apps for smart buildings — the base component for smart cities. (Johnson’s Metasys management system, for example, feeds data to its app-based Paoptix Platform to maximize energy efficiency in buildings.) In short, instrumented cities already are emerging. Smart nodes — including augmented buildings, utilities and public service systems — are establishing connections with one another, like axon-linked neurons.
But Goldstein, who was best known in Chicago for putting tremendous quantities of the city’s data online for public access, emphasizes instrumented cities are still in their infancy, and that their successful development will depend on how well we “parent” them.
“I hesitate to refer to ‘Big Data,’ because I think it’s a terribly overused term,” Goldstein said. “But the fact remains that we can now capture huge amounts of urban data. So, to me, the biggest challenge is transitioning the fields — merging public policy with computer science into functional networks.”…”

What Jelly Means


Steven Johnson: “A few months ago, I found this strange white mold growing in my garden in California. I’m a novice gardener, and to make matters worse, a novice Californian, so I had no idea what these small white cells might portend for my flowers.
This is one of those odd blank spots — I used the call them Googleholes in the early days of the service — where the usual Delphic source of all knowledge comes up relatively useless. The Google algorithm doesn’t know what those white spots are, the way it knows more computational questions, like “what is the top-ranked page for “white mold?” or “what is the capital of Illinois?” What I want, in this situation, is the distinction we usually draw between information and wisdom. I don’t just want to know what the white spots are; I want to know if I should be worried about them, or if they’re just a normal thing during late summer in Northern California gardens.
Now, I’m sure I know a dozen people who would be able to answer this question, but the problem is I don’t really know which people they are. But someone in my extended social network has likely experienced these white spots on their plants, or better yet, gotten rid of them.  (Or, for all I know, ate them — I’m trying not to be judgmental.) There are tools out there that would help me run the social search required to find that person. I can just bulk email my entire address book with images of the mold and ask for help. I could go on Quora, or a gardening site.
But the thing is, it’s a type of question that I find myself wanting to ask a lot, and there’s something inefficient about trying to figure the exact right tool to use to ask it each time, particularly when we have seen the value of consolidating so many of our queries into a single, predictable search field at Google.
This is why I am so excited about the new app, Jelly, which launched today. …
Jelly, if you haven’t heard, is the brainchild of Biz Stone, one of Twitter’s co-founders.  The service launches today with apps on iOS and Android. (Biz himself has a blog post and video, which you should check out.) I’ve known Biz since the early days of Twitter, and I’m excited to be an adviser and small investor in a company that shares so many of the values around networks and collective intelligence that I’ve been writing about since Emergence.
The thing that’s most surprising about Jelly is how fun it is to answer questions. There’s something strangely satisfying in flipping through the cards, reading questions, scanning the pictures, and looking for a place to be helpful. It’s the same broad gesture of reading, say, a Twitter feed, and pleasantly addictive in the same way, but the intent is so different. Scanning a twitter feed while waiting for the train has the feel of “Here we are now, entertain us.” Scanning Jelly is more like: “I’m here. How can I help?”

Social media in crisis events: Open networks and collaboration supporting disaster response and recovery


Paper for the IEEE International Conference on Technologies for Homeland Security (HST): “Large-scale crises challenge the ability of public safety and security organisations to respond efficient and effectively. Meanwhile, citizens’ adoption of mobile technology and rich social media services is dramatically changing the way crisis responses develop. Empowered by new communication media (smartphones, text messaging, internet-based applications and social media), citizens are the in situ first sensors. However, this entire social media arena is unchartered territory to most public safety and security organisations. In this paper, we analyse crisis events to draw narratives on social media relevance and describe how public safety and security organisations are increasingly aware of social media’s added value proposition in times of crisis. A set of critical success indicators to address the process of adopting social media is identified, so that social media information is rapidly transformed into actionable intelligence, thus enhancing the effectiveness of public safety and security organisations — saving time, money and lives.”

Open Government Strategy Continues with US Currency Production API


Eric Carter in the ProgrammableWeb: “Last year, the Executive branch of the US government made huge strides in opening up government controlled data to the developer community. Projects such as the Open Data Policy and the Machine Readable Executive Order have led the US government to develop an API strategy. Today, ProgrammableWeb takes a look at another open government API: the Annual Production Figures of United States Currency API.

The US Treasury’s Bureau of Engraving and Printing (BEP) provides the dataset available through the Production Figures API. The data available consists of the number of $1, $5, $10, $20, $50, $100 notes printed each year from 1980 to 2012. With this straightforward, seemingly basic set of data available, the question becomes: “Why is this data useful“? To answer this, one should consider the purpose of the Executive Order:

“Openness in government strengthens our democracy, promotes the delivery of efficient and effective services to the public, and contributes to economic growth. As one vital benefit of open government, making information resources easy to find, accessible, and usable can fuel entrepreneurship, innovation, and scientific discovery that improves Americans’ lives and contributes significantly to job creation.”

The API uses HTTP and can return requests in XML, JSON, or CSV data formats. As stated, the API retrieves the number of bills of a designated currency for the desired year. For more information and code samples, visit the API docs.”
 

Introduction to Linked Open Data (LOD)


Paper by Ivan Herman, presented at the International Conference on Dublin Core and Metadata Applications 2013: “The goal of the tutorial is to introduce the audience into the basics of the technologies used for Linked Data. This includes RDF, RDFS, main elements of SPARQL, SKOS, and OWL. Some general guidelines on publishing data as Linked Data will also be provided, as well as real-life usage examples of the various technologies.”

A permanent hacker space in the Brazilian Congress


Blog entry by Dan Swislow at OpeningParliament: “On December 17, the presidency of the Brazilian Chamber of Deputies passed a resolution that creates a permanent Laboratório Ráquer or “Hacker Lab” inside the Chamber—a global first.
Read the full text of the resolution in Portuguese.
The resolution mandates the creation of a physical space at the Chamber that is “open for access and use by any citizen, especially programmers and software developers, members of parliament and other public workers, where they can utilize public data in a collaborative fashion for actions that enhance citizenship.”
The idea was born out of a week-long, hackathon (or “hacker marathon”) event hosted by the Chamber of Deputies in November, with the goal of using technology to enhance the transparency of legislative work and increase citizen understanding of the legislative process. More than 40 software developers and designers worked to create 22 applications for computers and mobile devices. The applications were voted on and the top three awarded prizes.
The winner was Meu Congress, a website that allows citizens to track the activities of their elected representatives, and monitor their expenses. Runner-ups included Monitora, Brasil!, an Android application that allows users to track proposed bills, attendance and the Twitter feeds of members; and Deliberatório, an online card game that simulates the deliberation of bills in the Chamber of Deputies.
The hackathon engaged the software developers directly with members and staff of the Chamber of Deputies, including the Chamber’s President, Henrique Eduardo Alves. Hackathon organizer Pedro Markun of Transparencia Hacker made a formal proposal to the President of the Chamber for a permanent outpost, where, as Markun said in an email, “we could hack from inside the leviathan’s belly.”
The Chamber’s Director-General has established nine staff positions for the Hacker Lab under the leadership of the Cristiano Ferri Faria, who spoke with me about the new project.
Faria explained that the hackathon event was a watershed moment for many public officials: “For 90-95% of parliamentarians and probably 80% of civil servants, they didn’t know how amazing a simple app, for instance, can make it much easier to analyze speeches.” Faria pointed to one of the hackathon contest entries, Retórica Parlamentar, which provides an interactive visualization of plenary remarks by members of the Chamber. “When members saw that, they got impressed and wondered, ‘There’s something new going on and we need to understand it and support it.’”

A World Of Wikipedia And Bitcoin: Is That The Promise Of Open Collaboration?


Science 2.0: “Open Collaboration, defined in a new paper as “any system of innovation or production that relies on goal-oriented yet loosely coordinated participants who interact to create a product (or service) of economic value, which they make available to contributors and non-contributors alike” brought the world Wikipedia, Bitcoin and, yes, even Science 2.0.
But what does that mean, really? That’s the first problem with vague terms in an open environment. It is anything people want it to be and sometimes what people want it to be is money, but hidden behind a guise of public weal.
TED’s lesser cousin TEDx is a result of open collaboration but there is no doubt it has successfully leveraged the marketing of TED to sell seats in auditoriums, just as it was designed to do. Generally, Open Collaboration now is less like its early days, where a group of like-minded people got together to create an Open Source tool, and more like corporations. Only they avoid the label, they are not quite non-profits and not quite corporations.
And because they are neither they can operate free of the cultural stigma. Despite efforts to claim that Wikipedia is a hotbed of misogyny and blocks out minorities, the online encyclopedia has endured just fine. Their defense is a simple one; they have no idea what gender or race or religion anyone is and anyone can contribute – it is a true open collaboration. Open Collaboration is goal-oriented, they lack the infrastructure to obey demands that they become about social justice, so the environments can be less touchy-feely than corporations and avoid the social authoritarianism of academia.
Many open collaborations perform well even in ‘harsh’ environments, where some minorities are underrepresented and diversity is lacking or when products by different groups rival one another. It’s a real puzzle for sociologists. The authors conclude that open collaboration is likely to expand into new domains, displacing traditional organizations, because it is so mission-oriented. Business executives and civic leaders should take heed – the future could look a lot more like the 1940s.”

Building Creative Commons: The Five Pillars Of Open Source Finance


Brett Scott: “This is an article about Open Source Finance. It’s an idea I first sketched out at a talk I gave at the Open Data Institute in London. By ‘Open Source Finance’, I don’t just mean open source software programmes. Rather, I’m referring to something much deeper and broader. It’s a way of framing an overall change we might want to see in the financial system….

You can thus take on five conceptually separate, but mutualistic roles: Producer, consumer, validator, community member, or (competitive or complementary) breakaway. And these same five elements can underpin a future system of Open Source Finance. I’m framing this as an overall change we might want to see in the financial system, but perhaps we are already seeing it happening. So let’s look briefly at each pillar in turn.
Pillar 1: Access to the means of financial production
Very few of us perceive ourselves as offering financial services when we deposit our money in banks. Mostly we perceive ourselves as passive recipients of services. Put another way, we frequently don’t imagine we have the capability to produce financial services, even though the entire financial system is foundationally constructed from the actions of small-scale players depositing money into banks and funds, buying the products of companies that receive loans, and culturally validating the money system that the banks uphold. Let’s look though, at a few examples of prototypes that are breaking this down:

  1. Peer-to-peer finance models: If you decide to lend money to your friend, you directly perceive yourself as offering them a service. P2P finance platforms extend that concept far beyond your circle of close contacts, so that you can directly offer a financial service to someone who needs it. In essence, such platforms offer you access to an active, direct role in producing financial services, rather than an indirect, passive one.
  2. There are many interesting examples of actual open source financial software aimed at helping to fulfil the overall mission of an open source financial system. Check out Mifos and Cyclos, and Hamlets (developed by Community Forge’s Matthew Slater and others), all of which are designed to help people set up their own financial institutions
  3. Alternative currencies: There’s a reason why the broader public are suddenly interested in understanding Bitcoin. It’s a currency that people have produced themselves. As a member of the Bitcoin community, I am much more aware of my role in upholding – or producing – the system, than I am when using normal money, which I had no conscious role in producing. The scope toinvent your own currency goes far beyond crypto-currencies though: local currencies, time-banks, and mutual credit systems are emerging all over
  4. The Open Bank Project is trying to open up banks to third party apps that would allow a depositor to have much greater customisability of their bank account. It’s not aimed at bypassing banks in the way that P2P is, but it’s seeking to create an environment where an ecosystem of alternative systems can plug into the underlying infrastructure provided by banks

Pillar 2: Widespread distribution
Financial intermediaries like banks and funds serve as powerful gatekeepers to access to financing. To some extent this is a valid role – much like a publisher or music label will attempt to only publish books or music that they believe are high quality enough – but on the other hand, this leads to excessive power vested in the intermediaries, and systematic bias in what gets to survive. When combined with a lack of democratic accountability on the part of the intermediaries, you can have whole societies held hostage to the (arbitrary) whims, prejudices and interests of such intermediaries. Expanding access to financial services is thus a big front in the battle for financial democratisation. In addition to more traditional means to buildingfinancial inclusion – such as credit unions and microfinance – here are two areas to look at:

  • Crowdfunding: In the dominant financial system, you have to suck up to a single set of gatekeepers to get financing, hoping they won’t exclude you. Crowdfunding though, has expanded access to receiving financial services to a whole host of people who previously wouldn’t have access, such as artists, small-scale filmmakers, activists, and entrepreneurs with no track record. Crowdfunding can serve as a micro redistribution system in society, offering people a direct way to transfer wealth to areas that traditional welfare systems might neglect
  • Mobile banking: This is a big area, with important implications for international development and ICT4D. Check out innovations like M-Pesain Kenya, a technology to use mobile phones as proto-bank accounts. This in itself doesn’t necessarily guarantee inclusion, but it expands potential access to the system to people that most banks ignore

Pillar 3: The ability to monitor
Do you know where the money in the big banks goes? No, of course not. They don’t publish it, under the guise of commercial secrecy and confidentiality. It’s like they want to have their cake and eat it: “We’ll act as intermediaries on your behalf, but don’t ever ask for any accountability”. And what about the money in your pension fund? Also very little accountability. The intermediary system is incredibly opaque, but attempts to make it more transparent are emerging. Here are some examples:

  • Triodos Bank and Charity Bank are examples of banks that publish exactly what projects they lend to. This gives you the ability to hold them to account in a way that no other bank will allow you to do
  • Corporations are vehicles for extracting value out of assets and then distributing that value via financial instruments to shareholders and creditors. Corporate structures though, including those used by banks themselves, have reached a level of complexity approaching pure obsfucation. There can be no democratic accountability when you can’t even see who owns what, and how the money flows. Groups likeOpenCorporates and Open Oil though, are offering new open data tools to shine a light on the shadowy world of tax havens, ownership structures and contracts
  • Embedded in peer-to-peer models is a new model of accountability too. When people are treated as mere account numbers with credit scores by banks, the people in return feel little accountability towards the banks. On the other hand, if an individual has directly placed trust in me, I feel much more compelled to respect that

Pillar 4: An ethos of non-prescriptive DIY collaboration
At the heart of open source movements is a deep DIY ethos. This is in part about the sheer joy of producing things, but also about asserting individual power over institutionalised arrangements and pre-established officialdom. Alongside this, and deeply tied to the DIY ethos, is the search to remove individual alienation: You are not a cog in a wheel, producing stuff you don’t have a stake in, in order to consume stuff that you don’t know the origins of. Unalienated labour includes the right to produce where you feel most capable or excited.
This ethos of individual responsibility and creativity stands in contrast to the traditional passive frame of finance that is frequently found on both the Right and Left of the political spectrum. Indeed, the debates around ‘socially useful finance’ are seldom about reducing the alienation of people from their financial lives. They’re mostly about turning the existing financial sector into a slightly more benign dictatorship. The essence of DIY though, is to band together, not via the enforced hierarchy of the corporation or bureaucracy, but as part of a likeminded community of individuals creatively offering services to each other. So let’s take a look at a few examples of this

  1. BrewDog’s ‘Equity for Punks‘ share offering is probably only going to attract beer-lovers, but that’s the point – you get together as a group who has a mutual appreciation for a project, and you finance it, and then when you’re drinking the beer you’ll know you helped make it happen in a small way
  2. Community shares offer local groups the ability to finance projects that are meaningful to them in a local area. Here’s one for a solar co-operative, a pub, and a ferry boat service in Bristol
  3. We’ve already discussed how crowdfunding platforms open access to finance to people excluded from it, but they do this by offering would-be crowdfunders the chance to support things that excite them. I don’t have much cash, so I’m not in a position to actively finance people, but in my Indiegogo profile you can see I make an effort helping to publicise campaigns that I want to receive financing

Pillar 5: The right to fork
The right to dissent is a crucial component of a democratic society. But for dissent to be effective, it has to be informed and constructive, rather than reactive and regressive. There is much dissent towards the current financial system, but while people are free to voice their displeasure, they find it very difficult to actually act on their displeasure. We may loathe the smug banking oligopoly, but we’re frequently compelled to use them.
Furthermore, much dissent doesn’t have a clear vision of what alternative is sought. This is partially due to the fact that access to financial ‘source code’ is so limited. It’s hard to articulate ideas about what’s wrong when one cannot articulate how the current system operates. Most financial knowledge is held in proprietary formulations and obscure jargon-laden language within the financial sector, and this needs to change. It’s for this reason that I’m building the London School of Financial Activism, so ordinary people can explore the layers of financial code, from the deepest layer – the money itself – and then on to the institutions, instruments and networks that move it around….”

How Big Should Your Network Be?


Michael Simmons at Forbes: “There is a debate happening between software developers and scientists: How large can and should our networks be in this evolving world of social media? The answer to this question has dramatic implications for how we look at our own relationship building…

To better understand our limits, I connected with the famous British anthropologist and evolutionary psychologist, Robin Dunbar, creator of his namesake; Dunbar’s number.

Dunbar’s number, 150, is the suggested cognitive limit to the number of relationships we can maintain where both parties are willing to do favors for each other.


Dunbar’s discovery was in finding a very high correlation between the size of a species’ neocortex and the average social group size (see chart to right). The theory predicted 150 for humans, and this number is found throughout human communities over time….
Does Dunbar’s Number Still Apply In Today’s Connected World?
There are two camps when it comes to Dunbar’s number. The first camp is embodied by David Morin, the founder of Path, who built a whole social network predicated on the idea that you cannot have more than 150 friends. Robin Dunbar falls into this camp and even did an academic study on social media’s impact on Dunbar’s number. When I asked for his opinion, he replied:

The 150 limit applies to internet social networking sites just as it does in face-to-face life. Facebook’s own data shows that the average number of friends is 150-250 (within the range of variation in the face-to-face world). Remember that the 150 figure is just the average for the population as a whole. However, those who have more seem to have weaker friendships, suggesting that the amount of social capital is fixed and you can choose to spread it thickly or thinly.

Zvi Band, the founder of Contactually, a rapidly growing, venture-backed, relationship management tool, disagrees with both Morin and Dunbar, “We have the ability as a society to bust through Dunbar’s number. Current software can extend Dunbar’s number by at least 2-3 times.” To understand the power of Contactually and tools like it, we must understand the two paradigms people currently use when keeping in touch: broadcast & one-on-one.

While broadcast email makes it extremely easy to reach lots of people who want to hear from us, it is missing personalization. Personalization is what transforms information diffusion into personal relationship building. To make matters worse, email broadcast open rates have halved in size over the last decade.

On the other end of the spectrum is one-on-one outreach. Research performed by Facebook data scientists shows that one-on-one outreach is extremely effective and explains why:

Both the offering and the receiving of the intimate information increases relationship strength. Providing a partner with personal information expresses trust, encourages reciprocal self-disclosure, and engages the partner in at least some of the details of one’s daily life. Directed communication evokes norms of reciprocity, so may obligate partner to reply. The mere presence of the communication, which is relatively effortful compared to broadcast messages, also signals the importance of the relationship….”
