The hypothesis underlying our work is that the character of an urban area is defined not just by the the types of places found there, but also by the people who make the area part of their daily routine. To explore this hypothesis, given data from over 18 million foursquare check-ins, we introduce a model that groups nearby venues into areas based on patterns in the set of people who check-in to them. By examining patterns in these check-ins, we can learn about the different areas that comprise the city, allowing us to study the social dynamics, structure, and character of cities on a large scale.

There’s a lot to be lost. For example, all the information in apps – that data is not crawlable by web crawlers. You can’t search it.

The ways in which people connect to the internet are also much more varied today than they were in 2000. As a result, internet access is no longer synonymous with going online with a desktop computer.

On 8 June, 2011, Google, Facebook, Yahoo!, Akamai and Limelight Networks will be amongst some of the major organisations that will offer their content over IPv6 for a 24-hour “test flight”.

Not need to worry about access. IPv4 access will still be available. But you should know that IPv6 is designed to succeed Internet Protocol version 4. The new address space will support 2^128 addresses. To make things clearer, every person on Earth could get a-29-digit number of IPv6 addresses. That’s a lot. Why? Because we are running out of IPv4 addresses.

Taking advantage of this new Internet Protocol version could not only take care of our need for more IP addresses but also lead to great innovation. Imagine a world where you can control every device on your home remotely, let’s say from your mobile phone. Of course you can already do this. But this is something slightly different.

You can test your IPv6 connection on ipv6test.google.com. If you need a more technical take on IPv6 you should read RFC 2460.

ifttt works like this: ifthisthenthat.

Having thought about it for a while I came up with this task:

if New starred item in your Google Reader then Read later with Instapaper

So now every time I star an item in Google Reader, I know this will automatically send the item to Instapaper. Note that ifttt is currently in beta and tasks poll for new trigger data every 15 minutes.

The yellow pins are stations, the red pins trains. The trains move in approximately real time.

Apart from that you can also stalk all trains currently on approach to a particular station via this live train map.

Note that this was done in only a few hours at Science Hackday.

First and foremost, the VP8 codec. Last summer Google acquired On2 for its video compression technology. Today, Google announced VP8 codec as part of a new project named WebM. By the way, VP8 is now open-source.

The WebM project is dedicated to developing a high-quality, open video format for the web that is freely available to everyone.

One of the most important things about this is that the WebM launch is supported by Mozilla, Opera, Google and more than forty other publishers, software and hardware vendors! Read more here.

…including Microsoft!

In its HTML5 support, IE9 will support playback of H.264 video as well as VP8 video when the user has installed a VP8 codec on Windows.

What’s Great About WebM

• Very high quality video
• Great video playback performance, even on older computers
• 100% free and open to everyone
• Supported on popular video sites like YouTube

Later on, Adobe shared some HTML5 love on the stage.

The keynote continued with the Chrome Web Store. The Chrome Web Store opens later this year.

Users will be able to discover a broad range of amazing web apps while developers will be able to reach millions of new users.

Next was Wave. Google Wave has been opened up to everyone as of today (also part of Google Apps as of today).

The keynote ended with an extensive reference to App Engine, GWT and some great things coming from Google + VMWare.

VMWare has been working with Google to bring an open-source layer for the cloud

I am guessing Day 2 will be all about Android. Woo hoo!

P.S. By the time I am writing this Google Buzz APIs come into play. Take a look here.

Outdated plugins are a major source of security and stability risk for web users, and some studies have put the proportion of users with older versions as high as 80%.

Just visit mozilla.com/plugincheck/ to run a plugin check for your browser.

You should also check out SecBrowsing, another powerful tool that helps you keep your browser and plugins up-to-date. If you are using Google Chrome, there is a SecBrowsing extension that alerts you if plugins are out-of-date.
