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

By Dave Borowitz, Google Git Engineer, with thanks to Augie Fackler, Lucas Bergman, Jacob Lee, and Shawn Pearce Cross-posted from the Google Open Source Blog Git . Git is a popular distributed version control system (DVCS) like Mercurial, and it is used by many popular projects including the Linux kernel and Android.Now, when you
create a project or visit your existing project’s Administration > Source tab, you have the option of choosing Git as your version control system. You’ll enjoy all the same great Google Project Hosting features, like project updates, advanced issue tracking, and an easy-to-use VCS-backed wiki—only now, you can do it with Git. You can also create an instant server-side clone of any existing Git repository by clicking the "Create a clone" button on the project’s checkout page.
For more information, including an introduction to Git and tips on converting existing Subversion and Mercurial repositories, see the new
Git section of our support wiki.
Under the Hood
Since our original announcement of
Mercurial support , Git has grown significantly more popular and user-friendly, and on the technical side, it has added an efficient "smart" HTTP protocol that fits with Google’s HTTP-based infrastructure. (Note that this feature is only available in version 1.6.6 and later.)
Like our
Mercurial implementation , our Git implementation stores object data in a custom data store built on
Bigtable , which provides us with efficient, scalable source code repositories with near-instantaneous replication to multiple datacenters around the world. To fit with our existing Python-based system, our Git server implementation is powered in part by
Dulwich .
By Ali Pasha, Google Code Search distributed version control systems get more popular. Linux has been using one for several years and several large open source projects have migrated to using one in the last few years. In recognition of that, we are now announcing that we crawl Git and Mercurial repositories. GitHub and repo.or.cz . In addition to that, we also crawl Android , Chromium and Linux code. For Mercurial repositories, we now crawl most popular open source repositories including Mozilla, JDK, and NetBeans.
Feel free to provide feedback to let us know how we're doing.
