How WikiLeaks has changed today's media

(CNN) -- While investigating a recent story about the geopolitical battle for natural resources in the Arctic, I searched for unfiltered, candid dialogue on the issue.

Instead, I found a web of conflicting theories, opinions and political doublespeak.

So, as many journalists have done since 2009, I went to WikiLeaks.

Mining through the treasure trove of diplomatic cables released by the organization, I found recaps of blunt conversations between American ambassadors and foreign diplomats describing their thoughts on this geopolitical tug-of-war in the Arctic.

It is the kind of access that veteran journalists once spent their careers cultivating. Years ago, such conversations may have taken place in muted whispers in the back of a restaurant, an off-the-record conversation with a confidential source.

Today, these details are laid out for everyone to read, digitized and accessible with a quick keyword search.

This isn't gossip in the school lunch cafeteria; this is more like having a hidden camera in the principal's office recording 24 hours a day.

Leaks as a tactical weapon

WikiLeaks has been credited as a force for political change, from Egypt's revolution to the battle for resources in the Arctic Ocean.

Classified State Department cables released by the organization in late 2010 provided some of the spark that fueled the Tunisian revolution. Sympathetic detonations created a chain reaction that touched Egypt, Libya, Syria and Yemen.

Opinion: How WikiLeaks helped fuel Tunisian revolution

Julian Assange, the controversial founder of WikiLeaks, stops short of taking credit for the Arab Spring that has changed regimes in North Africa and threatens others in the Middle East.

It is apparent, though, that this kind of global change is exactly what Assange envisioned.

Assange believes that information kept classified by governments should be distributed freely. Leaks are the tactical weapon, redistribution of power the strategic objective.

There is no definitive manifesto written by Assange. My CNN colleagues and I talked to multiple sources, studied endless hours of behind-the-scenes footage of Assange and read nearly all his publications to develop a portrait of a shifting organization inextricably linked to an enigmatic leader.

Assange in the spotlight

Before founding WikiLeaks, Assange published his musings in an online community of digital anarchists known as Cypherpunks.

A sensor network in the rainforest - Next at Microsoft - Site Home ...

We’ve talked about the home and cities as connected places – how about the rainforest? Why does a rainforest in Brazil have a ton of sensors installed? Read on..

When we talk about the great advances that are being made in technology we often talk about the big ideas and the sweeping projects. We don’t always spend as much time thinking about the massive volume of fine details that go into those projects, but in the case of the Atlantic Rainforest Sensor Network that’s where the real work lies. Microsoft Research is working with researchers from Johns Hopkins and the University of Sao Paulo to gather minute-by-minute climate data from a small section of the Brazilian rainforest. These rainforests help regulate climate temperatures, create rainfall and provide a habitat for biodiversity.

This is both a fine-scale and a massive-scale undertaking . Fine-scale because there are 600 sensor nodes deployed throughout the Serra do Mar rainforest that are measuring and storing data on temperature, water vapor and solar radiation, at different elevations, above and below the rainforest canopy, every minute — and have been doing so since November 2009. Massive-scale because those individual measurements yield an enormous amount of data about how the climate of this specific area interacts with the global climate - the 600 sensors nodes deliver 18 million observations per month . Understanding the microclimate — through micrometeorology — is essential to understanding the macroclimate.

The sensor network is another example of connecting “things” in our physical world to the digital world. It also illustrates some fantastic work in solving specific logistical problems, such as how to ensure that sensitive electronic equipment functions in a wet environment and how to maintain battery life when you can’t be frequently scaling the trees to swap out the power source. The researchers have deployed light-footprint devices and use wireless connectivity to download and relay data for processing so they can avoid intruding on the environment they’re observing.

We’ve had sensors in our world for quite some time – think about the door that opens when you approach a store – that’s a motion sensor in action. In your pocket, you very likely have a GPS, digital compass and accelerometer, all of which are connected to the Internet. All of these sensors can start to enable completely new scenarios for making our lives easier. In the case of the rainforest, it’s more of a macro thing – using tiny devices to understand our physical world and tackle some big societal challenges.
