The most awesome 450 page presentation ever." That's how the authors call this slide show—and I agree. It is awesome. But knowing that it was made using only Google Docs and no extra software whatsoever, makes it truly unbelievable.

If you invited me to try and crack your password, you know the one that you use over and over for like every web page you visit, how many guesses would it take before I got it?

One of the simplest ways to gain access to your information is through the use of a Brute Force Attack. This is accomplished when a hacker uses a specially written piece of software to attempt to log into a site using your credentials.

And how fast could this be done? Well, that depends on three main things, the length and complexity of your password, the speed of the hacker's computer, and the speed of the hacker's Internet connection.

Google Breadcrumb allows you to create an easy-to-use mobile learning application without any programming experience; your application works with only three additions to plain text. Easy to create and readable on Internet-enabled smart-phones or computers, Google Breadcrumb gives you maximum output for the development time.

Impressive services

Only last week Google splashed out on Writely, a web-based word processor that requires no downloads or installation and just runs in a browser window.

They are just the tip of an iceberg

a lot of work around standards for Web 2.0 work has yet to properly started, let alone finished.

Some of this work has happened. Things like RSS feeds, XML etc have made it simpler for computers to share complicated bits of data. But it hasn't gone far enough and it's not just data.

This new system of farming was remarkable because it was sustainable; the output of food was increased dramatically, without endangering the long-term viability of English agriculture. But just as a sustainable agriculture had been achieved, the development of chemical fertilisers and other external inputs undermined this sustainability. An essentially organic agriculture was gradually replaced by a farming system that depended on energy-intensive inputs dependent on the exploitation of fossil fuels.

A gigantic Chinese dairy farm is now the world’s largest methane farm, turning a massive source of greenhouse gas emissions into a lucrative renewable energy source.

The jury system may not survive if it is undermined by social networking sites

"We cannot stop people tweeting, but if jurors look at such material, the risks to the fairness of the trial will be very serious, and ultimately the openness of the trial process on which we all rely, would be damaged."

The strength of currencies has become a source of tension between some of the world's biggest economies, especially the US and China. Brazil's finance minister went as far as to warn that his country would not stand idly by as international currency wars threatened its competitiveness. What was he talking about? Watch this animated guide to find out about why countries are falling out with each other because of their currencies.

These days one witty Tweet, one clever blog post, one devastating video - forwarded to hundreds of friends at the click of a mouse - can snowball and kill a product or damage a company's share price.

It's a dramatic shift in consumer power. But what if companies could harness this power and turn it to their advantage?

At the most basic, these tools measure the volume of social media chatter. Researchers at Hewlett Packard showed that they can accurately predict a Hollywood movie's box office takings by counting how often it is mentioned on Twitter before it opens.

"What we think is good for the consumer doesn't matter - it's what the consumer thinks is good that matters."

When you link the consumer to the manufacturer there are huge areas of opportunity

It's the internet, of course, that makes crowdsourcing possible - on a global scale.

If the company could monitor sales of ice cream - or bottled water or sun tan cream - on hot days like this one and then gauge future demand, he said, it could alter the way the company behaved

Real-time - the act of responding to events as they happen - is changing the way that the world behaves.

The software has also been blamed for exacerbating the financial crisis. Computer programmes automatically sold stocks as fear spread in the markets, because their algorithms have built-in "sell" orders.

by watching his Chatter dashboard, Benioff says he can spot - and reward - pivotal individuals who might not have come to his attention in the past

If these tools take off, then perhaps 'pivotal individuals' within companies really will get noticed, and businesses will become better meritocracies as a result.

Of 3,500 employees in a range of companies and economies, 58% said they would contribute more ideas to their company if they were more likely to be rewarded for them.

The lone genius, beavering away in the seclusion of his lab is how most of us imagine the great moments of innovation have come into being. But is this really the whole story?

"[Good ideas] come from crowds, they come from networks. You know we have this clichéd idea of the lone genius having the eureka moment.

"And so much of that is because it's wonderfully set up for other people to build on top of other people's ideas. In many cases without asking for permission.

How could you survive without the media, the internet and a mobile phone for 24 hours?

I didn't expect it, but being deprived of the media for 24 hours resulted in my day-to-day activities becoming so much harder to carry out than usual.
