Wireless data from every light bulb

What if every light bulb in the world could also transmit data? At TEDGlobal, Harald Haas demonstrates, for the first time, a device that could do exactly that. By flickering the light from a single LED, a change too quick for the human eye to detect, he can transmit far more data than a cellular tower -- and do it in a way that's more efficient, secure and widespread

The case for anonymity online

The founder of 4chan, a controversial, uncensored online imageboard, describes its subculture, some of the Internet "memes" it has launched, and the incident in which its users managed a very public, precision hack of a mainstream media website.

How the NSA betrayed the world's trust -- time to act

Recent events have highlighted, underlined and bolded the fact that the United States is performing blanket surveillance on any foreigner whose data passes through an American entity -- whether they are suspected of wrongdoing or not. This means that, essentially, every international user of the internet is being watched, says Mikko Hypponen. An important rant,

Massive-scale online collaboration

After re-purposing CAPTCHA so each human-typed response helps digitize books, Luis von Ahn wondered how else to use small contributions by many on the Internet for greater good.

Fighting viruses, defending the net

What is the Internet, really?

Uber's plan to get more people into fewer cars

Uber didn't start out with grand ambitions to cut congestion and pollution. But as the company took off, co-founder Travis Kalanick wondered if there was a way to get people using Uber along the same routes to share rides, reducing costs and carbon footprint along the way. The result: uberPOOL, the company's carpooling service, which in its first eight months took 7.9

The Web as random acts of kindness

How the Internet will (one day) transform government

The open-source world has learned to deal with a flood of new, oftentimes divergent, ideas using hosting services like GitHub -- so why can’t governments?

Why massive open online courses (still) matter

2013 was a year of hype for MOOCs (massive open online courses). Great big numbers and great big hopes were followed by some disappointing first results. But the head of edX, Anant Agarwal, makes the case that MOOCs still matter — as a way to share high-level learning widely and supplement (but perhaps not replace) traditional classrooms. Agarwal shares his vision of

Tracking the trackers

As you surf the Web, information is being collected about you. Web tracking is not 100% evil -- personal data can make your browsing more efficient; cookies can help your favorite websites stay in business. But, says Gary Kovacs, it's your right to know what data is being collected about you and how it affects your online life. He unveils a Firefox add-on to do just

The Internet could crash. We need a Plan B

In the 1970s and 1980s, a generous spirit suffused the Internet, whose users were few and far between. But today, the net is ubiquitous, connecting billions of people, machines and essential pieces of infrastructure -- leaving us vulnerable to cyber-attack or meltdown. Internet pioneer Danny Hillis argues that the Internet wasn't designed for this kind of scale

How to separate fact and fiction online

By the end of this talk, there will be 864 more hours of video on YouTube and 2.5 million more photos on Facebook and Instagram. So how do we sort through the deluge?

Linda Liukas is helping to educate problem-solving kids, encouraging them to see computers not as mechanical, boring and complicated but as colorful, expressive machines meant to be tinkered with. In this talk, she invites us to

Technology hasn't changed love. Here's why

In our tech-driven, interconnected world, we've developed new ways and rules to court each other, but the fundamental principles of love have stayed the same, says anthropologist Helen Fisher. Our faster connections, she suggests, are actually leading to slower, more intimate relationships. At 12:20, couples therapist and relationship expert Esther Perel steps in to

Three types of online attack

Cybercrime expert Mikko Hypponen talks us through three types of online attack on our privacy and data -- and only two are considered crimes. "Do we blindly trust any future government? Because any right we give away, we give away for good."

The conversation we're not having about digital child abuse

We need to talk to kids about the risks they face online, says information security expert Sebastián Bortnik.

A Magna Carta for the web

Sir Tim Berners-Lee invented the World Wide Web 25 years ago. So it’s worth a listen when he warns us: There’s a battle ahead. Eroding net neutrality, filter bubbles and centralizing corporate control all threaten the web’s wide-open spaces. It’s up to users to fight for the right to access and openness. The question is, What kind of Internet do we want?

Art that lets you talk back to NSA spies

In 2013, the world learned that the NSA and its UK equivalent, GCHQ, routinely spied on the German government. Amid the outrage, artists Mathias Jud and Christoph Wachter thought: Well, if they're listening ... let's talk to them.

The 100,000-student classroom

Let's design social media that drives real change

Wael Ghonim helped touch off the Arab Spring in his home of Egypt ... by setting up a simple Facebook page. As he reveals, once the revolution spilled onto the streets, it turned from hopeful to messy, then ugly and heartbreaking. And social media followed suit. What was once a place for crowdsourcing, engaging and sharing became a polarized battleground. Ghonim asks:

The interspecies internet? An idea in progress

Apes, dolphins and elephants are animals with remarkable communication skills. Could the internet be expanded to include sentient species like them? A new and developing idea from a panel of four great thinkers -- dolphin researcher Diana Reiss, musician Peter Gabriel, internet of things visionary Neil Gershenfeld and Vint Cerf, one of the fathers of the

How better tech could protect us from distraction

How often does technology interrupt us from what we really mean to be doing? At work and at play, we spend a startling amount of time distracted by pings and pop-ups — instead of helping us spend our time well, it often feels like our tech is stealing it away from us. Design thinker Tristan Harris offers thoughtful new ideas for technology that creates more meaningful

The year open data went worldwide

At TED2009, Tim Berners-Lee called for "raw data now" -- for governments, scientists and institutions to make their data openly available on the web. At TED University in 2010, he shows a few of the interesting results when the data gets linked up.

Reinventing the encyclopedia game

Prompted by the Encyclopaedia Britannica ending its print publication, performance poet Rives resurrects a game from his childhood.

Governments don't understand cyber warfare. We need hackers

The Internet has transformed the front lines of war, and it's leaving governments behind. As security analyst Rodrigo Bijou shows, modern conflict is being waged online between non-state groups, activists and private corporations, and the digital landscape is proving to be fertile ground for the recruitment and radicalization of terrorists. Meanwhile, draconian

Why I keep speaking up, even when people mock my accent

Artist Safwat Saleem grew up with a stutter — but as an independent animator, he decided to do his own voiceovers to give life to his characters.

What really happens when you mix medications?

If you take two different medications for two different reasons, here's a sobering thought: your doctor may not fully understand what happens when they're combined, because drug interactions are incredibly hard to study.

In this thoughtful talk, he calls on us to strengthen the bonds between technology and the humanities, and he reminds us that

How AI can bring on a second Industrial Revolution

"The actual path of a raindrop as it goes down the valley is unpredictable, but the general direction is inevitable," says digital visionary Kevin Kelly — and technology is much the same, driven by patterns that are surprising but inevitable.
