Today we're announcing the API dashboard in Google Merchant Center, which makes it easier for online merchants who use the Google Content API for Shopping to debug their API requests.

If you’re an API user, you can now view a comprehensive timeline and list of errors that occurred while making requests to the API, sorted by the number of times the errors occurred for faster prioritization. For each error, the dashboard also displays example request and response pairs, making it easier to locate and fix errors in your requests.

The Web Audio API, currently available in Chrome, provides a considerable amount of aural power to developers interested in integrating audio into their apps and games. Low latency audio playback, audio generation and realtime effects are available with a sensible API in Chrome stable.

We worked with to develop Technitone, a web audio experience that lets you join other players to plot tones on a grid, construct melodies and modify the output with a robust toolset of effects.

Click on over and poke around.
  • Your tone samples can come from your own recordings, or any of the available samples.
  • The left side Tools panel offers realtime audio filters, like echo reverb and pitch shift.
  • We keep you connected to other players in realtime using WebSockets and Node.js.
  • You can drop into solo mode or invite your friends to join you in a session.
  • Get inspired by others’ audio creations in the gallery.
If you’re interested in the techniques and software behind the project, take a look at the case study with plenty of sample code and demos on HTML5 Rocks:

Google Translate is designed to help people understand each other regardless of which human language they use. So it’s appropriate that Google Translate now includes Esperanto, which was created more than 100 years ago to further the goal of a universal language. Esperanto is the 64th language supported by Google Translate, which makes it extra-special to nerds because, of course, 64 is 2^6, or 1000000 binary.

Going back before human language (or humans), a research team in China has discovered a forest that was buried in ash 300 million years ago. The team found intact trees and plants preserved just as they were back then. Now they just have to bring in some very large vacuum cleaners to tidy up the place.

Finally, here’s some astronomy fun for your weekend. On Saturday and Sunday, Jupiter, Venus, and the Moon will converge and shine brightly in the night sky.

Go out and take a look!

Hey, glad to see you made it over to our new home on Google Developers Blog! We like it here and hope you do too. As you might know, on Fridays we take a break and do a Fridaygram post just for fun. Each Fridaygram item must pass only one test: it has to be interesting to us nerds. Ĝuu vian semajnfinon!

Last September we announced the Google+ API and introduced our Google Developers site as our planned new home for developer information. Since then, we’ve made steady progress in building - by migrating existing content from, and by adding new pages and features to the new site. Our goal with the Google Developers site is to bring together all developer resources, programs, events, tools, and community into one place. wasn’t built in a day (it’s been around for almost 7 years), and it will take some time to make the new Google Developers site at your single destination for all the resources we offer. But we’re working toward that goal every day. Soon, all our information will be on this new Google Developers site, and Google Code will return to its roots as an open source project hosting service.

Google Developers logo

As part of this project, today we’re introducing a new identity, complete with a new look, to unify all of our developer offerings. Our new logo says Google Developers, and that's intentional: it reflects our focus on you, not just the tools we provide.

Another part of this update is the new blog you’re reading right now: Google Developers Blog. We’re going to use this blog to continue to provide you with useful news and updates about new developer tools and technologies, ways to speed up your apps and sites, upcoming events, and of course, fun stuff on Fridays. In addition to the blog, we’ll continue to share and converse on our +Google Developers page.

Thanks for all your support over the years, and welcome to the new Google Developers community!

Google Public DNS is a fast, free DNS service that we introduced a little more than 2 years ago. As the Official Google Blog post aptly puts it, “DNS acts like the phone book of the Internet”, translating from human-readable URLs to all-numeric IP addresses. Google Public DNS started as an experimental service and has now become the most-used public DNS service in the world with over 70 billion requests per day, mostly from outside the U.S. Will the next step be support for users in more distant places? (Probably not there.)

Speaking of faraway places, astronomers using images from the Hubble space telescope have found black hole HLX-1, which appears to be all that’s left of a dwarf galaxy that once contained other stars. The theory is that this late galaxy was torn apart by a nearby spiral galaxy, leaving only HLX-1. The other stars became part of the larger galaxy.

While you’re musing on this supermassive black hole, consider some much tinier creatures: little chameleons, just about one inch long, recently discovered in Madagascar. Scientists think this miniaturization might be an evolutionary response to limited resources.

Tiny chameleon: he comes and goes, he comes and goes

Finally, we can’t help but jump on the Linsanity bandwagon. Of course, we’re doing it in a nerdy way by pointing you to this article (interesting even for non-sports fans) about why talent evaluation is so tricky.

On Fridays we take a break and do a Fridaygram post just for fun. Each Fridaygram item must pass only one test: it has to be interesting to us nerds. Special thanks to Wired Science for having many excellent posts this week.

An attractive feature of Web programming is a rapid development cycle. Reloading the application after the source code has changed takes a fraction of a second. We want to offer you that same experience when using Dart, and today we’re making Mac and Linux binaries available that integrate the Dart VM into Chromium.

This technology preview allows you to run your Dart programs directly on the Dart VM in Chromium and avoid a separate compilation step. Over time, these programs will take advantage of the VM’s faster performance and lower startup latency.

Dart has been designed from the start to work with the entire modern web, and we’re simultaneously continuing to improve our fast Dart-to-JavaScript compiler. Both the Dart VM and modern JavaScript engines are first-class targets for Dart.

This release of Chromium with Dart VM integration is a technology preview, and should not be used for day-to-day browsing. After more testing and developer feedback, we plan to eventually include the Dart VM in Chrome.

Today’s release of the Chromium + Dart VM integration is another step forward for the open source "batteries included" Dart platform. Our goal is to help you build complex, high performance apps for the modern web, and we encourage you to try Dart and let us know what you think.

Anton Muhin is an engineer at Google Saint Petersburg who recently worked on making V8 VM and DOM bindings faster and now is working on integrating the Dart VM into Chromium. Before that he worked on the Google Calendar backend.

Vijay Menon is a software engineer at Google Seattle working on integrating the Dart language and runtime into the browser. His background is in compilers, runtime systems, and parallel programming.

Yesterday, the Chrome Developer Relations team launched several new resources, including the Field Guide to Web Applications. It’s a new resource that is designed to help web developers create great web apps. We’ve heard loud and clear from users that they want more and better web apps, and we hope this new field guide will enable you to create those web apps. Our fictitious author Bert Appward guides you through topics like the properties of web applications, design fundamentals, tips for creating great experiences, and a few case studies that put best practices to use. Whether you're building your first web app or are just looking for ways to improve your existing apps, I hope you'll find the field guide useful.

We built the field guide to embody the principles and best practices that it preaches. We stepped away from the normal webpage look, and instead designed the experience around a field guide. We used many CSS3 features like box-shadow, opacity, multiple backgrounds and more to provide a rich, visual experience. To make sure that it worked offline, we used AppCache and other than some URL rewriting techniques, didn't use any server-side code. We used the HTML5 History API to maintain page state even though everything is served from a single HTML page. We've started working on a new case study about the field guide, so check back soon for that!

Last year we added image results to Google Custom Search Engines to enable sites to offer image-only results that showcase photos and other digital images. For site owners who want more flexibility in presentation, they are also now available from the Custom Search API.

Read more about accessing Image Results from the Custom Search API or try it out in the Custom Search API Explorer. For billing purposes, image queries will be treated the same as web queries. If you are still using the deprecated Google Image Search API, now’s a great time to switch!

Below is an example of an image search to find small jpeg images of flowers:

With a valid key and cse id, here is a possible json result returned for an image item:
"kind": "customsearch#result",
"title": "flower-photo",
"htmlTitle": "\u003cb\u003eflower\u003c/b\u003e-photo",
"link": "",
"displayLink": "",
"snippet": "photo of flower",
"htmlSnippet": "photo of \u003cb\u003eflower\u003c/b\u003e",
"mime": "image/jpeg",
"image": {
"contextLink": "",
"height": 100,
"width": 100,
"byteSize": 6104,
"thumbnailLink": "",
"thumbnailHeight": 82,
"thumbnailWidth": 82

which you can use to render the image in your own site.

Note that you need to enable image search in your custom search engine control panel for the custom image search to work.

Nam Nguyen works on the JSON/Atom Custom Search API, which lets developers retrieve and display results from Google Custom Search programmatically. He is dedicated to making developers' lives a little easier by providing a simple API.

Over the past year, has become a top destination for developers craving to learn more about HTML5. Today, we have over 60 articles and tutorials covering the latest HTML5 tech, published by 30 contributors from around the world! We've worked hard to bring great content to the site as quickly as possible, but it's been challenging to consolidate so much information as HTML5 continues to push the web forward and evolve at an accelerated pace.

HTML5 Rocks logo

Today, we're launching an updated HTML5Rocks with better tools for finding content, including an edgy new look and "rocking" logo. As our content expands, finding things becomes more important. To address this, we've created "persona pages" with catered content in 3 different verticals (Games, Business, Mobile). If you're one of those developers, finding content relevant to you should now be a snap. We've also consolidated many of the different components (Updates, Studio, Playground) into the main site and have deeply integrated the HTML5 technology classes to bring a better identity to the content.

All in all, it's a little bit Punk and a little bit Rock and Roll.

Lastly, if you're interested in contributing to the site, it's an open source project and we'd love to have your expertise. See our contributors guide.

Unicode was created with the ambitious goal of representing every human language, with room left over for a whole bunch of symbols, too. More than 20 years after Unicode was started, over 60% of the pages on the web are now encoded in Unicode. That’s pretty good growth when you consider that Unicode’s coverage was less than 5% of the web in 2005. Having a standard like Unicode is important because, as Mark Davis writes, "The more documents that are in Unicode, the less likely you will see mangled characters (what Japanese call mojibake) when you're surfing the web."

In news of older stuff, a Russian expedition that has been working for 10 years has finally drilled through Antarctic ice and reached Lake Vostok, a huge freshwater lake more than 12,000 feet below the surface. The ice has covered this lake for at least 15 million years, which is well before the work on Unicode began. Eventually the team will take samples of the lake water, looking for signs of life and other ancient treasures.

Finally, you can go back even further in time and listen to the song of a cricket that was around during the Jurassic period, 165 million years ago. That cricket really sounds great for its age.

On Fridays we take a break and do a Fridaygram post just for fun. Each Fridaygram item must pass only one test: it has to be interesting to us nerds.

Today at FOSDEM I was proud to announce Google Summer of Code 2012.

This will be the 8th year for Google Summer of Code, an innovative program dedicated to introducing students from colleges and universities around the world to open source software development. The program offers student developers stipends to write code for various open source projects with the help of mentoring organizations from all around the globe. Over the past seven years Google Summer of Code has had 6,000 students from over 90 countries complete the program. Our goal is to help these students pursue academic challenges over the summer break while they create and release open source code for the benefit of all.

Spread the word to your friends! If you know of a university student that would be interested in working on open source projects this summer, or if you know of an organization that might want to mentor students to work on their open source projects, please direct them to our Google Summer of Code 2012 website where they can find our timeline along with the FAQs. And stay tuned for more details coming soon!

Most software developers started getting interested in technology at an early age. With that in mind, Google Roots in Science and Engineering (RISE) is a program that annually awards grants to groups that come up with great new ways to teach students in Computer Science (CS) and science, technology, engineering, and math (STEM). This year’s awards were just announced. The winners included a program that helps primary school students in Dublin, girls in the San Francisco Bay Area, and kids in Uganda who want to learn about technology.

Scientists love to have reproducible results so they can test theories and ideas. What if you’d like to reproduce the creation of a galaxy? That task is still out of scale for humans, but scientists at the Laboratoire pour l'Utilisation de Lasers Intenses (LULI) have figured out a lab procedure that simulates the magnetic fields in newly formed galaxies. The experimental version uses lasers and carbon rods in place of clouds of gas and dark matter, but the results are useful, and you don’t need a galaxy-sized lab to work in.

Narrowing our view from giant galaxies to little spiders, a new study says spider webs are not just strong, but also have the ability to become either stiff or soft, as necessary. Spider webs are also designed to stay as strong as possible when strands are damaged. So spiders are good engineers.

Finally, you might use some of your weekend time to ponder this Vi Hart video about SpongeBob SquarePants and Fibonacci sequences.

Fridaygram posts are just for fun. Fridaygrams are designed for your Friday afternoon and weekend enjoyment. Each Fridaygram item must pass only one test: it has to be interesting to us nerds, and we certainly love our lasers.
