By Matt Atterbury and Joshua Marantz, Pagespeed Automatic Team @import helps web designers modularize the implementation of their sites. The drawback to using @import is performance. Each @import is a new HTTP request, and every level of @import costs an additional serial round-trip between browser and server, since the browser does not know the URI of the imported CSS file until it downloads, parses, and executes the file that’s importing it. Here’s a waterfall diagram of a simple HTML page that uses @import to load a CSS file that includes a background image:mod_pagespeed 0.10.21.2 , which supports the new feature flatten_css_imports .child themes that override their parent theme (http://codex.wordpress.org/Child_Themes) because that feature uses @imports. But every web page and web user benefits from CSS that’s fast and well-structured, so if you’re an Apache administrator, download mod_pagespeed today and read more on our code site .Matt Atterbury and Joshua Marantz are Software Engineers on Google’s Pagespeed Automatic team in Cambridge, MA, which is dedicated to making the web faster for everyone. When not coding, Matt is probably on his bike. Josh has been working on making software run fast for several decades, at Google and before that on accelerated chip simulation.

By Nicolas Garnier, Developer Relations we launched the OAuth 2.0 Playground , a tool enabling you to easily experiment with the OAuth 2.0 protocol and APIs that use the protocol.
The OAuth 2.0 Playground
Support for the OAuth 2.0 Client-side flow Client-side flow by simply changing a setting in the OAuth 2.0 configuration dialog. Once set, every subsequent authorization request is performed using the client-side flow, and the playground’s interface and logic adapt accordingly.
Setting the OAuth flow type
Support for newer OAuth 2.0 drafts Bearer prefix and the access_token URL parameter locations. This makes the playground compatible with most APIs supporting OAuth 2.0 drafts 10 to 25 .
Setting the access token location
Display available API operations Find available Request URIs button, the operations along with their associated HTTP Methods and URIs are displayed on the right-hand side. This should help you quickly set up your request to the Google APIs without needing to search through the online documentation.

By Amit Fulay, Product Manager, Google+ Hangouts
Cross-posted from the Google+ Developers Blog
launched a preview of the Hangouts API a few months ago. Today we're moving this API out of preview, and enabling developers to launch and share their hangout apps with the entire Google+ community!
Initiate a group video chat with up to 10 people
Control hangout microphones, cameras, speakers and volume levels
Add sound effects and attach image overlays to faces
Set UI elements such as the video feed, chat pane, and notifications
It’s easy to get started: read the documentation , build and publish your app, and then let users know. You can easily get the word out in one of two ways: 1) post a link to it on Google+, and/or 2) add the new hangout button to your website. In either case, anyone who clicks will start a new hangout with your app running inside. It then appears in the “Recent” apps pane for future hangouts.Aces Hangout , Cacoo , Scoot & Doodle , Slideshare , Clubhouse Challenge by Bravo, and Google Effects. We’re looking forward to seeing what you can dream up in the weeks and months ahead.Google+ , and happy building!Amit Fulay is Product Manager for Google+ Hangouts.Posted by Scott Knaster , Editor

By Scott Knaster, Google Developers Blog Editor Street View as the cool Google Maps feature that gives you a peek at your destinations as you map them out. This week, Street View went off-road – way off, all the way to the Amazon Basin . Instead of streets, the Street View team photographed forests, villages, and rivers . The team used more than 50,000 photos to build the Amazon views, and the scenery is much more beautiful than most streets.

By Navneet Joneja, Product Manager Google Cloud Storage enables you to use our storage and network infrastructure to store and access your data with high reliability , scale and performance. Today, we’re launching several frequently requested new features:Signed URLs and updated browser uploads short-lived signed URLs to address any object stored in Google Cloud Storage. This feature gives your application another powerful tool to control access to any piece of data. You can also use this feature to enable browser-based uploads from your end users to Google Cloud Storage without requiring them to have Google accounts (browser-based uploads were previously limited to the interoperable API). URL signing is implemented using PKCS-12 keys and the industry-standard RSA algorithm and is currently experimental.Cross-Origin Resource Sharing configuring storage buckets to return appropriate Cross-Origin Resource Sharing (CORS) headers, which streamlines the development of advanced JavaScript applications (such as browser-based games) using Google Cloud Storage. Other uses include serving web fonts from Google Cloud Storage and enabling trusted JavaScript access from your App Engine applications.gsutil 3.0 A refactored, cleaner code-base

Google Prediction API
Google URL Shortener
Google OAuth 2.0 Authorization Server
Google APIs Console
Google APIs Client Libraries for Python, Java, and PHP
draft 25 of the OAuth 2.0 specification . An application implements the following steps to authenticate with a Service Account:Generate a JSON structure.
Sign the JSON structure with a private key, and encode it as a JSON Web Token (JWT).
Send the JWT to Google’s OAuth 2.0 Authorization Server in exchange for an access token.
Send the access token to Google Cloud Storage or the Google Prediction API.
Python , Java , and PHP wrap these steps into a few lines of code and abstract the error-prone signing and encoding operations from your applications. We strongly encourage you to use these libraries for this type of interaction. We will be expanding support to other client libraries (including Ruby and .NET). Library developers can find the specifics of the protocol in the OAuth 2.0 Service Accounts documentation .App Engine & Storage , App Engine & Prediction . Service Accounts generalize this App Engine capability by making it available to other server-side platforms. When using another server-side platform, you can create a Service Account through the Google APIs Console . See the Google APIs Console documentation for more information on creating a Service Account.OAuth 2.0 Google group .Justin Smith is a Google Product Manager and works on authentication and authorization technologies.

Because neutrinos rarely collide with other particles, the message was able to pass through the Earth successfully. The team used a binary code to send the word neutrino to the other side. And once again, science fiction becomes fact, sort of.Hide personal results , then search for binary and see how many results you get.Once a week we post a Fridaygram, in which we take a break from the real news and have some fun.
