redletterdave writes "Thanks to a newly developed audio extraction technology called optical scanning, the Smithsonian was able to recover the voice of Alexander Graham Bell from one of his hundreds of discs he donated to the museum, which were once considered 'mute artifacts.' Since many of the collected recordings are very fragile due to their age and experimental nature, optical scanning is a non-invasive procedure that creates a high-resolution digital map of the disc or cylinder, which is then reconstructed and used to simulate the motion of a stylus moving through its grooves to reproduce the original audio content. Bell, who created this recording on a wax and cardboard disc on April 15, 1885, can be heard clearly saying, 'In witness whereof — hear my voice, Alexander Graham Bell.'"

Google has released documentation for the Mirror API, the interface that programmers will use to write services for Glass. The contents include everything from quick start guides for Java and Python to in-depth developer guides and best practices, and starter projects and libraries are available for download. The news comes just as the first Glass units are beginning to roll off the production line.
Glass is a web app
We already saw many of the implementation details in Google's SXSW presentation, but everything is presented here in much more detail. Services are "installed" by authorizing them to post to your Glass timeline with OAuth 2.0, and those apps post text, images, and other data to your device using JSON objects and HTTP...
Today, a large collection of Web hosting and service companies announced that they will support Railgun, a compression protocol for dynamic Web content. The list includes the content delivery network and Web security provider CloudFlare, cloud providers Amazon Web Services and Rackspace, and thirty of the world’s biggest Web hosting companies.
Railgun is said to make it possible to double the performance of websites served up through Cloudflare’s global network of data centers. The technology was largely developed in the open-source Go programming language launched by Google; it could significantly change the economics of hosting high-volume websites on Amazon Web Services and other cloud platforms because of the bandwidth savings it provides. It has already cut the bandwidth used by 4Chan and Imgur by half. “We've seen a ~50% reduction in backend transfer for our HTML pages (transfer between our servers and CloudFlare's),” said 4Chan’s Chris Poole in an e-mail exchange with Ars. “And pages definitely load a fair bit snappier when Railgun is enabled, since the roundtrip time for CloudFlare to fetch the page is dramatically reduced. We serve over half a billion pages per month (and billions of API hits), so that all adds up fairly quickly.”
Rapid cache updates
Like most CDNs, CloudFlare uses caching of static content at its data centers to help overcome the speed of light. But prepositioning content on a forward server typically hasn’t helped performance much for dynamic webpages and Web traffic such as AJAX requests and mobile app API calls, which have relatively little in the way of what’s considered static content. That has created a problem for Internet services because of the rise in traffic for mobile devices and dynamic websites.
