As part of Google’s initiative to make the web faster, over the past few months we have released a number of tools to help site owners speed up their websites. We launched the Page Speed Firefox extension to evaluate the performance of web pages and to get suggestions on how to improve them, we introduced the Speed Tracer Chrome extension to help identify and fix performance problems in web applications, and we released a set of closure tools to help build rich web applications with fully optimized JavaScript code. While these tools have been incredibly successful in helping developers optimize their sites, as we’ve evaluated our progress, we continue to notice a single component of web pages is consistently responsible for the majority of the latency on pages across the web: images.
Most of the common image formats on the web today were established over a decade ago and are based on technology from around that time. Some engineers at Google decided to figure out if there was a way to further compress lossy images like JPEG to make them load faster, while still preserving quality and resolution. As part of this effort, we are releasing a developer preview of a new image format, WebP, that promises to significantly reduce the byte size of photos on the web, allowing web sites to load faster than before.
Images and photos make up about 65% of the bytes transmitted per web page today. They can significantly slow down a user’s web experience, especially on bandwidth-constrained networks such as a mobile network. Images on the web consist primarily of lossy formats such as JPEG, and to a lesser extent lossless formats such as PNG and GIF. Our team focused on improving compression of the lossy images, which constitute the larger percentage of images on the web today.
To improve on the compression that JPEG provides, we used an image compressor based on the VP8 codec that Google open-sourced in May 2010. We applied the techniques from VP8 video intra frame coding to push the envelope in still image coding. We also adapted a very lightweight container based on RIFF. While this container format contributes a minimal overhead of only 20 bytes per image, it is extensible to allow authors to save meta-data they would like to store.
While the benefits of a VP8 based image format were clear in theory, we needed to test them in the real world. In order to gauge the effectiveness of our efforts, we randomly picked about 1,000,000 images from the web (mostly JPEGs and some PNGs and GIFs) and re-encoded them to WebP without perceptibly compromising visual quality. This resulted in an average 39% reduction in file size. We expect that developers will achieve in practice even better file size reduction with WebP when starting from an uncompressed image.
To help you assess WebP’s performance with other formats, we have shared a selection of open-source and classic images along with file sizes so you can visually compare them on this site. We are also releasing a conversion tool that you can use to convert images to the WebP format. We’re looking forward to working with the browser and web developer community on the WebP spec and on adding native support for WebP. While WebP images can’t be viewed until browsers support the format, we are developing a patch for WebKit to provide native support for WebP in an upcoming release of Google Chrome. We plan to add support for a transparency layer, also known as alpha channel in a future update.
We’re excited to hear feedback from the developer community on our discussion group, so download the conversion tool, try it out on your favorite set of images, and let us know what you think.

The Google Web Toolkit can be used to create applications that, in the same code base, work well on an iPhone and a traditional desktop browser.
Our developer program started in 2005 with a handful of APIs and developer advocates. Fast forward to today: Google offers over 100 APIs, dozens of developer tools, and a raft of developer advocates around the world. Obviously, a lot has changed and the Web has matured significantly. Google has also evolved and matured, and we felt that it was time to step back and rethink how we interact with and support our developer community. We believe we can make it easier to find what you’re looking for, and facilitate connections with others in the Google Developer community. We know we can do better and we want your input so that we can understand your needs — and what drives you — better.
We want to know what inspires you as a developer and how Google can support you. What does being a Google developer mean to you? Tell us what’s important to you and how we can make your experience as a Google developer better. Like any good open source project, the Google developers project needs your contributions. Share your story so we can we better support your success — and we may just pick you to be featured.
You can add a video (it's easy, really!) directly from the page, on your mobile phone, or write to us here. However you share with us, we’re looking forward to hearing what you have to say.

Social bookmarking is a method for Internet users to organize, store, manage and search for bookmarks of resources online. Unlike file sharing, the resources themselves aren't shared, merely bookmarks that reference them.
"Social bookmarking" allows you to save
and
share links to your favorite stories, tools, blogs
and communities on iVillage, like creating a "Favorites" menu that you can access from anywhere, and that you can allow friends to see.
What is social bookmarking? It is tagging a website and saving it for later. Instead of saving them to your web browser, you are saving them to the web. And, because your bookmarks are online, you can easily share them with friends.
What Can Social Bookmarking Do For Me? :
Not only can you save your favorite websites and send them to your friends, but you can also look at what other people have found interesting enough to tag. Most social bookmarking sites allow you to browse through the items based on most popular, recently added, or belonging to a certain category like shopping, technology, politics, blogging, news, sports, etc.
Social Media
The best way to define social media is to break it down. Media is an instrument on communication, like a newspaper or a radio, so social media would be a social instrument of communication.
In Web 2.0 terms, this would be a website that doesn't just give you information, but interacts with you while giving you that information. This interaction can be as simple as asking for your comments or letting you vote on an article, or it can be as complex as Flixster recommending movies to you based on the ratings of other people with similar interests.
Think of regular media as a one-way street where you can read a newspaper or listen to a report on television, but you have very limited ability to give your thoughts on the matter.
Social media, on the other hand, is a two-way street that gives you the ability to communicate too.

Google Apps is designed to provide a secure and reliable platform for your data. Until today, Google Apps administrators had to sign requests for calls to Google Apps APIs using their username and password (this is called ClientLogin Authorization).
Yet sharing passwords across sites can pose security risks. Furthering our commitment to make the cloud more secure for our users, today we are pleased to announce support for OAuth authorization on Google Apps APIs.
There are several advantages to using OAuth instead of the username/password model:
The Google Apps APIs that support the OAuth signing mechanism are:
OAuth support for Google Apps APIs is another step towards making Google Apps the most secure, reliable cloud based computing environment for organizations. To learn more about OAuth support and other administrative capacities launched in Google Apps this quarter, join us for a live webinar on Wednesday, September 29th at 9am PT / 12pm EST / 5pm GMT.
Administrators for Google Apps Premier, Education, and Government Editions can use OAuth authorization for Google Apps APIs starting today.For more information about the OAuth standard, visit http://oauth.net.
