Gordon Brown: Wiring a web for global good

There's been some follow-up from Rafael Behr's piece in the Observer saying 'The Tories think the internet favours them. They're wrong' which repeats the meme that Gordon Brown is a web luddite whilst 'webcameron' gets it.

This is just wrong and the following talk by Brown at TedGlobal last month shows why.

Yes, Labour has a crap web operation. Yes, Gordon should stop jigging around in Downing Street videos.

But this presentation off the Westminster bubble circuit is seemingly effortless and masterful and demonstrates that he 'gets it' web-wise.

Another way to look at lawnmowing



The great Michael Pollan interviewed by Bill Maher about the new documentary Food Inc.



Here he explains a plant's-eye view in a fantastic TED talk.



"I'm a dupe of the lawns, whose goal in life is to out compete the trees"

"Looking at the world from another species point of view is a cure for the disease of human self-importance"

Incidentally, WTF can't Oxbridge do something like TED online?

Tech lessons from Africa

Ushahidi: Crowdsourcing Crisis Information

Ushahidi, which means ”testimony” in Swahili, is an open source engine. The project was developed in the effort to better map out reports of violence in Kenya. This was after the post-election fallout at the beginning of 2008.

The aim of Ushahidi is to create a platform that any person or organization can use to set up his or her own platform for collecting and visualizing information. They explain that, ‘the core Ushahidi platform allows for a plug-in and extensions that can be customized for different locales and needs. The tool is open source allowing others to download, implement and use the engine so that they can bring awareness to crises in their own region.’

The core engine is built on the premise that gathering crisis information from the general public provides new insights into events happening in ‘near real-time.’

Ushahidi is also being utilised in the Indian election by Vote Report India.

Users contribute direct SMS, email, and web reports on violations of the Indian Election Commission’s Model Code of Conduct (PDF). The platform will then aggregate these direct reports with news reports, blog posts, photos, videos and tweets related to the elections from all relevant sources, in one place, on an interactive map.

Vote Report India aim is to not only increase transparency and accountability in the Indian election process, but also provide the most complete picture of public opinion in India during the elections.

Vote Report India is a non-partisan all-volunteer collaboration between software developers, designers, academics, and other professionals.

Here's Erik Hersman, aka WhiteAfrican, talking to TED about Ushahidi:



Here's a paper on the use of the Ushahidi platform in the Gaza war. Scroll to sec.5 for new media.

Recent research from ResearchICTAfrica reveals that Kenyans are spending incredible amounts on mobile communication as a proportion of income.

Here’s how it breaks down. The average Kenyan spends over 50% of their disposable income on mobile communication. For the bottom 75% of the population, that figure goes up to 63.6%. In terms of total individual income, the average Kenyan spends 16.7% of their income on mobile communication. That figure rises to 26.6% when looking at the bottom 75% of the population.

Africans are paying for mobile communication in spite of how expensive it is, not because of how affordable it is and because access to mobile communication is critical for people. Even if you are digging a ditch by the side of the road, day labour is now organised via SMS.

Nathan Eagle of MIT recently gave a talk to eTech where he explained about the mobile scene in Africa.



Entrepreneurs are constantly finding new uses for the technology.

A Kenyan water pump manufacturer combines an mobile-mPesa-enabled, solar-powered metering system with their water pumps. They give water pumps away for free and then make a profit by selling access to water via Safaricom’s mPesa service. Send the pump 20 Kenyan Shillings and it pumps 20 litres of water for you. This has increased the water pump companies business and made water more accessible to those who need it.

However, as Steve Song points out:
When a single mobile operator is a gatekeeper to water supply, something is wrong. For any village in this situation, [Kenya's largest mobile network]Safaricom can charge whatever they like.

If we accept the premise that, in places like Kenya, no one can afford not to have access to a phone, then one cannot help but feel that something needs to be done. A flour milling company in South Africa was recently fined more than 45 million Rand by the Competition Commission for price fixing and collusion. I think it is time to take a serious look at mobile operators.

Imagine an alternate reality where Africans paid less than 5% percent of their income on mobile communications and all phones operated on an IP-based network so that any new African innovation might be unlimited in terms of scope. Then we would see mobile-enabled social and economic innovation taking off in Africa.

As Nathan explains, African colleges and universities are turning out a lot of entrepreneurial tech talent. Unfortunately, much of this then migrates. Things like his work and the establishment of companies like Google Kenya is helping to stem this flow. Barcamp's have been held in Kenya and are coming up in Nigeria.

London is hosting a chance for sponsors and African innovators to meet up this weekend at Africa Gathering.

WhiteAfrican's blog is full of tales of tech innovation in Africa. Here he talks about the problems facing the next generation of techies in Liberia. Here's his list of African tech events.

Here Jonathan Gosier explains about his work in developing a tech hub in Uganda.




The rest of the world has a lot to learn from Africa, most obviously in developments around mobile phones.

Designing out racism

One of the issues which I wrote about during the US election campaign was the meme, constantly repeated in the BBC's reporting, of the 'Bradley effect'. This is when people say they will but actually don't vote for the black candidate.

One of the odd issues with this is that in the campaign for California Governor in 1982, which this 'effect' is named after, race wasn't a factor (or at least a trivial one). The reason black candidate Tom Bradley lost was because a supposedly 'anti-gun' proposition turned out larger numbers than expected of rural and small town voters.

That sort of 'wedge' issue has been used elsewhere to bring out the vote, most notably the Republicans who used gay marriage propositions in this way in 2000 and 2004.








In a presentation at the TED conference, the baseball statistician cum political pollster guru Nate Silver of fivethirtyeight.com, who most accurately predicted the US election result, elaborated on the question of race in the elections using the presidential outcomes to draw out social and design implications.

He started off by talking about quite how big of a win Obama had.

Electoral maps between 2004 and 2008 show a profound shift towards blue, or liberal, voting. But there’s a block of states - centered on Arkansas, and roughly following the Appalachians - which voted more strongly against Obama than they did against Clinton. And in Louisiana, roughly 1 in 5 white voters told pollsters that race had been a factor in choosing not to vote for Obama - that compares to roughly 4% in states like New York and California.

This made no difference overall because these are less populated states with less national electoral weight.

There's little evidence of race deciding US elections recently and Silver has statistically dismantled its role.

But Silver turns these stats inside out to ask if racism is predictable.

He looked for relationships between independent variables and racism as an electoral factor and found a strong correlation - low education levels correlate closely with racial-based voting. Highly rural states also showed this pattern, though it’s less dramatic than the educational pattern.

The General Social Survey, asks “Does anyone of the opposite race live in your neighborhood?” And, the answers to this are stratified upon density: In the city, yes. In the suburbs, mainly yes. In rural areas, not nearly as much.

He looked at political affiliation - there are more Republicans in monoracial neighborhoods, but it’s not a dramatic difference. Similarly, there’s not much difference in opinion regarding affirmative action. But a question about interracial marriage gets dramatically different results in monoracial neighborhoods - people in these neighborhoods are twice as likely to support a law banning interracial marriage.

What he gleans from this is that if something is predictable then it is designable.

The goal is to facilitate interaction with people of other races. For example a university-based mixing program, sending students from NYU to the University of Arkansas as a form of cultural exchange.

More dramatically Silver suggested that you need to try to create interracial neighborhoods, to reengineer cities.

Cities designed in the 1970s and 80s might actually have helped America become more conservative under Reagan, he suggested.

He thinks that urban design is hugely important to achieving integration: grids vs the windy streets in many parts of suburbia, where grids are better. At the end of the day, he said cul de sacs lead to conservatives.

This idea also relates to a point made by the new black Attorney General, Eric Holder:
In a speech to Justice Department employees marking Black History Month, Holder said the workplace is largely integrated but Americans still self-segregate on the weekends and in their private lives.

Even when people mix at the workplace or afterwork social events, Holder argued, many Americans in their free time are still segregated inside what he called "race-protected cocoons."

"Saturdays and Sundays, America in the year 2009 does not in some ways differ significantly from the country that existed almost 50 years ago. This is truly sad," said Holder.
Although racism in the UK has a very different history I wonder if mapping answers to “does anyone of the opposite race live in your neighborhood?” correlates to BNP voting?

Al Gore: New thinking on the climate crisis



In Al Gore's brand-new slideshow (premiering exclusively on TED.com), he presents evidence that the pace of climate change may be even worse than scientists were recently predicting, and challenges us to act with a sense of "generational mission" -- the kind of feeling that brought forth the civil rights movement -- to set it right. Gore's stirring presentation is followed by a brief Q&A in which he is asked for his verdict on the current political candidates' climate policies and on what role he himself might play in future.

Favorite line: "Junkies find veins in their toes when the ones in their arms and legs collapse."

Wow - Demo of stunning multi-touch intuitive screen



Hat tip to John Caswell.

Han is a research scientist for NYU's Courant Institute of Mathematical Sciences. Here, he demonstrates - for the first time publicly - his intuitive, "interface-free," touch-driven computer screen, which can be manipulated intuitively with the fingertips, and responds to varying levels of pressure


Here's the "demo, which drew spontaneous applause and audible gasps from the audience, begins with a simple lava lamp, then turns into a virtual photo-editing tabletop, where Han flicks photos across the screen as if they were paper snapshots" when the technology was first unveiled a year ago, from TED:



Here's another one via John about an amazing visualisation space with digital walls that become ceilings.



Found it interesting that the technology described as "a bit different from Powerpoint" actually ends in text based slides (for Nike apparently). According to John Sweller, a researcher from the University of New South Wales.

"It is effective to speak to a diagram, because it presents information in a different form. But it is not effective to speak the same words that are written, because it is putting too much load on the mind and decreases your ability to understand what is being presented."

"PowerPoint presentations can backfire if the information on the screen is the same as that which is verbalized because the audience's attention will be split between the two,"
