Google Launches First Beta Build of 64-Bit Chrome for Mac

Google today announced the launch of the first beta build of 64-bit Chrome for Mac, following the public release of 64-bit Chrome for Windows.

Earlier this month, Google added 64-bit support to Chrome Canary for OS X, the experimental build of its Chrome web browser, but with this new beta version, testers on the Beta channel will have access to 64-bit Chrome support.

According to Google, 64-bit support for Chrome will bring several speed and security improvements to the browser, in addition to decreasing the amount of memory it uses.

64-bit Chrome has become faster as a result of having access to a superior instruction set, more registers, and a more efficient function calling convention. Improved opportunities for ASLR enhance this version's security. Another major benefit of this change comes from the fact that most programs on a modern Mac are already 64-bit apps. In cases where Chrome was the last remaining 32-bit app, there were launch-time and memory-footprint penalties as 32-bit copies of all of the system libraries needed to be loaded to support Chrome. Now that Chrome's a 64-bit app too, we expect you'll find that it launches more quickly and that overall system memory use decreases.

64-bit support for the Windows Chrome beta was implemented in July with a stable release coming a a month afterwards, so a stable Mac release could possibly follow a similar timeline, coming in September.

It’s not just Amazon: Google is developing delivery drones too

Summary: Google is two years into developing “Project Wing,” which relies on a cross between a plane and a helicopter to deliver goods.

Amazon isn’t the only company putting serious thought into shipping packages via drone: Google is two years into building and testing a small hybrid between a plane and a helicopter that delivers items to people by dropping them down on a line.
An extensive article in The Atlantic details just how mature the technology is: Google partner Unmanned Systems Australia is already testing the drones in Australia, where unmanned aerial vehicle use is not so heavily controlled. The drones don’t land during deliveries. Instead, they quickly lower the package down on a line. The drone then pulls the line back up and flies away.

The project, which reportedly dozens of Google employees are assigned to, stems from the secretive Google X lab. It’s not yet ready for use by customers, and U.S. law would currently prohibit it, but The Atlantic reports that Google is confident the technology will be capable of making deliveries when the right time comes. MIT roboticist Nick Roy has shaped the project for the last two years, but is now returning to MIT. Dave Vos, a drone entrepreneur and 20-year veteran in the space, will replace him.

Google’s interest in drones means another deep and powerful wallet will be lobbying for their wide use in the U.S., where drone operators and the Federal Aviation Administration have been sparring over current rules that prohibit the commercial use of the vehicles. Google has been expanding its Shopping Express service, which could someday take on Amazon with same day deliveries. Like Amazon, Google understands that drones could further cut delivery times, not to mention gas use and reliance on human drivers.
