Google Enables SPDY HTTP in Chrome Browser

Internet

Google has enabled SPDY HTTP in it’s Chrome Browser. “Google enabled SPDY for Chrome in mid-January 2011 in a limited way, but is now running Chrome with SPDY, which replaces portions of HTTP and adds a few features at 100% over its own servers.”, reports Conceivablytech.

“The result is a dramatically increased page load performance that only works between Chrome (as it includes SPDY support) and Google’s servers (which supports the features for Google sites.) In effect, Google sites should load much faster in Chrome than in any other web browser.

SPDY is designed to overcome the shortcomings of HTTP, which was first documented in 1995 and related to web content that was much simpler than what we are developing and consuming today. Both TCP and HTTP have evolved into a bottleneck of data downloads and are constantly under scrutiny how these protocols can be made much more efficient in today’s world.

Google said that it saw pageload times to improve by 44 to up to 64%”

Journalists Are Aggregators

Media

Journalists Are Aggregators Too (And That’s A Good Thing) reports Techdirt.

“A bunch of folks have passed along this blog post from the Zunguzungu blog, which notes that journalists are aggregating too. I don’t like the use of the word “thieves” here, as I believe (yet again) that it’s a misleading and wrong use of the term, but I believe the usage here is in comparing the claims of some journalists that aggregators are “thieves.”

The real problem, however, is that journalists are, by their nature, thieves of words. You can call it what you like; you can say “Possibly I am old-fashioned,” and talk about how “actual journalists are laboring at actual history, covering the fever of democracy in Arab capitals and the fever of austerity in American capitals” (Keller) or you can brag about the “148 full-time editors, writers, and reporters engaged in the serious, old-fashioned work of traditional journalism” (Huffington), but all this “old fashioned” stuff is just a way of covering over something really basic about what “actual” journalists “traditionally” do, all the time: write down what other people say. They can exercise editorial discretion in how they integrate and harmonize the various quotes they’ve aggregated. They can confirm, they can contextualize, and they can (very rarely) manage to witness something with their own two eyes. They can produce collages out of stolen scraps. And they should do these things. But at the core of the journalistic process is the act, inescapably, of taking other people’s texts, weaving them together, and then placing them under your byline (with appropriate citation) and profiting from the activity.”

Facebook Announce Open Compute Project

Media

Facebook have announced the Open Compute Project, an initiative to share the custom-engineered technology in its first dedicated data center in Prineville, Oregon. This advanced technology delivered a 38 percent increase in energy efficiency at 24 percent lower cost for Facebook, and the specifications and best practices behind those gains will now be available to companies across the industry.

“Facebook and our development partners have invested tens of millions of dollars over the past two years to build upon industry specifications to create the most efficient computing infrastructure possible” said Jonathan Heiliger, vice president of technical operations at Facebook. “These advancements are good for Facebook, but we think they could benefit all companies. Today we’re launching the Open Compute Project, a user-led forum, to share our designs and collaborate with anyone interested in highly efficient server and data center designs. We think it’s time to demystify the biggest capital expense of an online business — the infrastructure”

Inspired by the success of open source software, Facebook is publishing technical specifications and mechanical CAD files for the Prineville data center’s servers, power supplies, server racks, battery backup systems and building design. This technology enabled the data center to achieve an initial power usage effectiveness (PUE) ratio of 1.07, compared with 1.5 for our existing facilities, which fall into the “best practice” category as defined by the U.S. Environmental Protection Agency*. Established by the Green Grid in 2007, PUE is an indicator of data center energy efficiency, and the lower the number, the better.

Facebook is releasing these designs as open hardware, aiming to encourage industry-wide collaboration around best practices for data center and server technology.

Advanced Micro Devices, Dell, HP and Intel are among the companies that co-developed technology with Facebook. In addition, Dell’s Data Center Solutions business will design and build servers based on the Open Compute Project specification. Synnex Corporation will also serve as a vendor for Open Compute Project servers, offering fully integrated and tested solutions based on customers’ specifications.

More information about the project, specifications and CAD files are available at http://opencompute.org/ Facebook Engineering page at http://www.facebook.com/Engineering

There is a down side to this: poorly written extensions can have a severe impact on the browsing experience, including on the overall performance of Firefox itself. This article offers some best practices and suggestions that can not only improve the performance of your extension, but also of Firefox itself.”
