Internet Archive
These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to. That way, as the pages that are referenced are changed or taken from the web, a link to the version that was live when the page was written will be preserved.
Then the Internet Archive hopes that references to these archived pages will be put in place of a link that would be otherwise be broken, or a companion link to allow people to see what was originally intended by a page's authors.
The goal is to
fix all broken links on the web .
Crawls of supported "No More 404" sites.
A daily crawl of more than 200,000 home pages of news sites, including the pages linked from those home pages. Site list provided by

[Cross-posted on the Google Research Blog and the Google Online Security Blog ] protect our users' security and privacy . One such project, RAPPOR (Randomized Aggregatable Privacy-Preserving Ordinal Response), provides a new state-of-the-art, privacy-preserving way to learn software statistics that we can use to better safeguard our users’ security, find bugs, and improve the overall user experience.randomized response , RAPPOR enables learning statistics about the behavior of users’ software while guaranteeing client privacy. The guarantees of differential privacy , which are widely accepted as being the strongest form of privacy , have almost never been used in practice despite intense research in academia . RAPPOR introduces a practical method to achieve those guarantees.on the Internet, nobody should know you’re a dog . To do this, you could ask each friend to answer the question “Are you a dog?” in the following way. Each friend should flip a coin in secret, and answer the question truthfully if the coin came up heads; but, if the coin came up tails, that friend should always say “Yes” regardless. Then you could get a good estimate of the true count from the greater-than-half fraction of your friends that answered “Yes”. However, you still wouldn’t know which of your friends was a dog: each answer “Yes” would most likely be due to that friend’s coin flip coming up tails.unwanted software is hijacking users’ settings.open-source project so that anybody can inspect and test its reporting and analysis mechanisms, and help develop the technology. We’ve written up the technical details of RAPPOR in a report that will be published next week at the ACM Conference on Computer and Communications Security .feedback we’ve received so far from academics and other stakeholders, and we’re looking forward to additional comments from the community. We hope that everybody interested in preserving user privacy will review the technology and share their feedback at rappor-discuss@googlegroups.com .
Every so often when reading a page written in a different language—especially Chinese, Korean, or Japanese (CJK) pages—you might see little boxes where letters should be, something that we call “tofu”. What's happened is that some of the characters are not supported by your computer. In July Google released Noto Sans CJK , the newest font in a family designed to cover 200+ languages in a harmonious way. As of Chrome OS 38, Noto is now the default sans serif and UI font for CJK languages.
Pan-CJK: Simplified and Traditional Chinese, Japanese, and Korean, all in a single font.Seven weights: Thin, Light, DemiLight, Regular, Medium, Bold, Black. ChromeOS has default support for Regular and Bold, with more coming soon.Free and open source: Freely available for everyone under the Apache License, v2.0 .Comprehensive character coverage: Covers all the CJK Ideographs in the Unicode Basic Multilingual Plane and a few hundred Ideographs in Unicode Plane 2. Also covered are over twelve thousand Korean Hangul characters with full support for Old Hangul. The total number of glyphs in each font instance is exactly 65,536, the maximum number of glyphs allowed by the OpenType font specification. Region-appropriate glyph forms: CJK-shared ideographic characters follow region writing conventions to look appropriate to Chinese, Japanese, and Korean users. Harmony: Noto Sans CJK and all other members of the Noto family are visually compatible with Noto Sans for English, so that text mixing English with another language looks harmonious.

Shipping Noto by default on ChromeOS is one step towards making “tofu” a thing of the past. You can learn more at the Noto homepage .
Today’s Chrome Beta channel release includes new tools to make web application development simpler and more powerful. Unless otherwise noted, changes described below apply to Chrome for Android, Windows, Mac, Linux, and Chrome OS.JavaScript Generators less than straightforward . It often involves several nested functions and non-linear program execution, making it hard to develop, maintain and debug. This is such a common pain point for developers that they've given it a name: callback soup.read more about them or see them in action .Web Animation Playback Control Web Animations is a powerful new API that unifies all of the animation APIs on the web. We shipped basic support in May with Chrome 36. In this release we've added playback control, with methods such as play() , pause() , and reverse() , and the ability to jump to a specific point in an animation's timeline. With our initial support, developers could create animations but not precisely control their playback. This next iteration enables animations that can react in real time to user input - as well as a variety of other creative uses.Web Application Manifest <meta> and <link> tags to trigger this behavior and deliver relevant resources such as icons. Having this embedded in every page was not only repetitive, but was a waste of bandwidth and put extra bits on the critical path .Manifests provide a way to wrap metadata about a web application into a single file, reducing duplication. Developers seeking to enable "add to homescreen " can define a title, landing page, default orientation, and different icons depending on size and screen density. You can see how it works today , but stay tuned for more properties to be added in later releases.Other updates in this release
The Beacon API enables developers to queue asynchronous network requests that will be sent, regardless of whether the user navigates to a new page
Scroll offsets (scrollTop , scrollLeft ) now return high-precision fractional values in preparation for high-DPI support
XMLHttpRequest progress event properties position and totalSize are now deprecated in favor of the loaded and total properties
