This is the last Fridaygram of 2011, and like most everybody else, we’re in a reflective mood. It’s also the 208th post on Google Code Blog this year, which means we’ve averaged more than one post every two days, so that’s plenty of stuff for you to read. What did we write about?

At Google, we love to launch. Many of our posts were about new APIs and client libraries. We also posted a bunch of times about HTML5 and Chrome and about making the web faster. And we posted about Android, Google+, and Google Apps developer news.

Many of our 2011 posts were about the steady progress of App Engine, Cloud Storage, and other cloud topics for developers. We also published several times about commerce and in-app payments.

2011 was a stellar year for Google I/O and other developer events around the world. Some of our most popular posts provided announcements, details, and recaps of these events. And we welcomed a couple dozen guest posts during Google I/O from developers with cool stories to tell.

The two most popular Code Blog posts of the year were both launches: the Dart preview in October, and the Swiffy launch in June.

Last, and surely least, I posted 26 Fridaygrams in an attempt to amuse and enlighten you. Thank you for reading those, and thanks for dropping by and reading all the posts we’ve thrown your way this year. See you in 2012!

And finally, please enjoy one more Easter egg.

Earlier this week, we launched a single Terms of Service for most of our APIs. You might know the Terms of Service (ToS) as those legal documents you click through quickly when you start using a new product, but they’re vitally important, as they specify exactly what you and we can expect from each other when you use our APIs. (Internally, we refer to the new terms as uToS [universal terms of service], pronounced "you toss".)

The project began some time ago as a general developer ToS cleanup. At the time, we looked at the Google Terms of Service shared across many consumer products, and figured developers deserved equal consideration. In reviewing the developer ToS documents, it became clear that there was plenty of language in common among various products. And this week, the new Terms launched, covering most APIs, with more to come in time. Of the APIs that are included, a few have additional terms, but these tend to be brief. And things overall are much simpler and cleaner than before.

This project is an example of something that affects every Google developer and Google too, and yet it’s not really a technical topic. This ToS simplification was no minor project: it was over two years in the making. Getting to simplify an important set of documents by removing over 125,000 words of text is a wonderful thing.

Speaking of universal things, the incredible Voyager 1 spacecraft is now about 18 billion kilometers from the sun and is nearing the end of our solar system. Voyager now inhabits a part of space between planets and other stars that has an intense magnetic field, among other unusual properties, and we’ll learn more about the place from Voyager itself. One scientist says that Voyager is now in a "stagnation region", and I think we all know what that feels like.

And finally, if you’re planning your holiday vacation over the weekend, you might want to see what happens if you ask Google Maps for walking directions from Rivendell to Mordor.


Fridaygram posts are just for fun, and sometimes even legal stuff can be 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.

This week we celebrated the 197th birthday of computing pioneer Lady Ada Lovelace with a nifty Google Doodle. Among other accomplishments, Ada is credited with publishing the world's first algorithm for use with Charles Babbage’s Analytical Engine.

Coincidentally, also this week we launched the latest episodes in our Women Techmakers series on Google Developers Live. We're highlighting women who are making big social impacts through their innovations in tech. Please check it out.

In other areas of science this week, researchers in Spain used zebra fish to test an idea about limbs evolving from fins. The scientists ramped up the activity of a particular gene, which caused the fish to produce rudimentary limbs instead of fins. This might be an evolutionary clue about where our own arms and legs came from.

Finally, it looks like the mystery of line drawings in the Peruvian desert has been solved, according to Clive Ruggles, who is an archaeoastronomer (which might be the coolest job title ever) and archaeologist Nicholas Saunders. Ruggles says the drawings are a labyrinth, and "This labyrinth was meant to be walked, not seen". Well said, and in that spirit, we hope you get out and take a walk of your own this weekend, even if you don’t have an awesome ancient labyrinth nearby.


Each Friday on this blog we skip our usual developer topics and offer interesting (we hope) stuff that’s not directly related to writing code.

You might already know that Google Search makes a handy calculator. Just type any calculation into a Google search box, and the answer is computed for you. Earlier this week, we added an even cooler, more powerful feature. Now, when you type a function, you’ll see it graphed.


As you can see in this image, you can graph more than one function at a time by separating them with commas. Once the graph is drawn, you can zoom and pan to see the sections and details you want. And the Google colors are a nice touch.

In other calculation-related news this week, the Hubble Space Telescope counted to 10,000. That’s the number of published scientific papers based on data gathered from Hubble. Although the telescope was launched back in 1990, it’s said to be in great shape and is taking great pictures, thanks largely to frequent service missions by astronauts. That should inspire you to change the oil in your car.

Finally, here’s one especially for you babies out there, and for those who know or are related to babies. The Nerdy Baby coloring book for very young scientists looks like a great way to nudge very small kids toward a proper nerdy upbringing. And when you’re not coloring, you can spend some time this weekend coming up with cool functions to graph on Google Search.


Fridaygram posts are just for fun. They're designed for your Friday afternoon and weekend enjoyment. Each Fridaygram item must pass only one test: it has to be interesting to us nerds (sometimes including nerdy babies).

This week Google Giving launched the Global Impact Awards, to recognize and reward achievements that use technology to improve people’s lives. The awards go to groups that have already accomplished dramatic results and provide continued funding so they can keep changing the world by providing clean water, protecting endangered species, and doing other wonderful things.



If you want to find out more about the Global Impact Awards, visit the home page, or learn about the other grant programs of Google Giving.

Meanwhile, near the moon, scientists have published the first mapping images from the tandem spacecraft Ebb and Flow, which reached lunar orbit about a year ago. This program, called GRAIL (Gravity Recovery and Interior Laboratory), uses the two spacecraft to study lunar features in great detail, providing unprecedented information about Earth’s moon. So far, the data shows craters, peaks, and volcanic formations, but no huge surprises like giant alien transformer robots.

Speaking of transformer robots, here’s one you can enjoy on video. Sure, it’s neither giant nor alien, but it’s still very cool, don’t you think? Have a great weekend!


On Fridays we depart from our usual developer topics and post a Fridaygram, which features interesting nerdy stuff for fun and knowledge. This week we acknowledge Walt Disney’s eleventy-first birthday, and the happy news that his creation Oswald the Lucky Rabbit will finally get a voice after 85 years of silence.

The latest version of Google Maps for Android can take you somewhere new: indoors. The Google Maps folks have plotted out a bunch of airports, shopping centers, stores, and other locations in the U.S. and Japan. Now you have one fewer excuse for staying at home.



From the shops to space: last Saturday NASA launched the Mars Science Laboratory (MSL), including the Curiosity rover. MSL will travel to Mars over the next 8 months before a planned touchdown next August 6th. Once there, Curiosity will conduct experiments to figure out if life was ever feasible in the landing area.

Finally, if you haven’t decided yet what you’re going to do this weekend, maybe you could fly in formation with jets like this dude did. Or you could clean out the fridge.

This week we launched a campaign to keep the Internet #freeandopen, ahead of a meeting of government agencies next week that could increase censorship and regulation of the Internet. We believe that Internet policies should be discussed and decided by the people who use it, not just governments. You can go to the site to learn more and find out what you can do. You can also watch Google Developers Live next Tue., Wed., and Thu. for live Hangouts on this topic. Your opinion matters!



Speaking of matter, researchers are eyeing data from the Large Hadron Collider for evidence of a new form of matter that has been theorized to exist but never seen. The new matter is a kind of gluon called color-glass condensate. Scientists noted that some wacky particles unexpectedly showed quantum entanglement when they traveled in the same direction after collisions. A new state of matter is a possible explanation.

Finally, take a look at this video of erupting lava from the Kilauea Volcano flowing into the ocean. You can also see a webcam view of the caldera, including some brave people watching from a safe distance. Maybe they’ll wave!


Each Friday on this blog we depart from the usual developer topics and present fun and interesting stuff that’s not necessarily related to writing code. Sometimes we even veer into an important topic, like the #freeandopen program mentioned in this post.

Earlier this week, our Google Maps API got a great new feature. When you build an application with the Maps API, you can now enable users to draw on the maps. There are tools for various shapes, so your users can draw circles or boxes to highlight locations, just like they would with physical maps. And to be even more like physical maps, users can use the tools to approximate drawing a coffee cup stain or a big crinkle.



Speaking of physical things, here’s one that exists in the real world, but barely makes a dent. Researchers in California have created what they say is the world’s lightest material. The material has a density of 0.9 mg/cc and is light enough to sit atop the fluff on a dandelion, although that usage seems impractical.

Finally, for weekend fun, take a look at this peer-reviewed paper entitled "A Vicious Cycle: A Cross-Sectional Study of Canine Tail-Chasing and Human Responses to It, Using a Free Video-Sharing Website". It will make you want to spend more time on YouTube, in the name of science.


Fridaygram is our weekly nerdy attempt at fun for developers. Fridaygrams have Google things, science stuff, and sometimes, Easter eggs.

Google Developers Live (GDL) is designed to bring you great technical content, live as it happens and archived for whenever you need it. We want GDL to teach you about our tools and platforms, but Eiji Kitamura, a Google Developer Advocate in Tokyo, had another idea: use the captions on GDL videos as a tool for picking up English while learning about technology. As Eiji says, “Learning English and technology at the same time is a killer feature, because it is time efficient, practical, and enjoyable”.


For the best translation, click the CC button and make sure English is selected (shown circled in red in the image above), and not English (transcribed). The English translations are usually available about a week after each event.

Eiji posted about this idea on the Google Developer Relations Japan Blog, and it proved to be very popular, so several other Googlers around the world picked up the thread and created their own versions of the post, translated into Korean, Spanish, and Hebrew, with more translated posts in the works. If you’re a developer learning English while studying a new technology, now you can absorb both at the same time.

Switching our focus to nature, we’ve often wondered: how many legs are enough? 2? 4? 100? The answer turns out to be 562 to 750, which is the number of legs you’ll find on llacme plenipes, a rare millepede species. This creature was long thought to be extinct, but according to a recent journal was rediscovered in 2006 in a densely foggy area of central California. (Note: humans thought the species was extinct, but llacme plenipes itself was not fooled.)

Finally, if you need some new gaming fun this weekend, check out Ingress, a game that takes place online and in the physical world. Just be sure to stop playing and come back to your family at some point.


On Fridays we depart from our usual fare of new tools and events, and instead tell you about general cool stuff you might find interesting. This week we’re wondering: are you disappointed to learn that millipedes don’t really have 1000 legs?

One of the most rewarding aspects of working on neat technology is when you can make a difference in the real world. Our Custom Search team has been collaborating with U. S. agencies to produce a job search engine for use by returning military veterans. This is especially cool because today is Veterans Day in the U. S.


Once you’ve seen the customized job search engine, I hope you’ll be inspired to use Custom Search or some other interesting technology to make a difference with your own projects. And speaking of interesting projects...

Wan and exhausted, a team of six men emerged last week from a mock spacecraft after spending almost a year and a half on a simulated trip to Mars. The six lived in windowless capsules in Moscow for 520 days to see how they would react to the confinement.

One physiologist, a trainer, a surgeon, and three engineers made up the diverse crew, who were said to be in good health at the end of the mission. Their virtual trip to Mars qualifies as either a really grueling job or a bizarre vacation.

Wonderful as the simulated Mars mission was, it can’t compete with this classic video – especially today. Have a great weekend!


Wondering what this post is doing on Google Code Blog? Once a week, on Friday, we lighten up and have a little fun, posting curious, clever, and interesting bits and pieces. One more thing: we hope you find one not-so-hidden date-appropriate message in this post.

Hey, wanna start a band? A new Chrome Experiment, JAM with Chrome, lets you play music in a web app and jam with others online in real time. You get to pick from 19 different instruments, including drums, guitars, and keyboards. Once you get really good, you can use shortcuts on your (computer) keyboard to play your instrument.



When you’ve had enough fun making music with your friends, you can explore how JAM with Chrome works. Take a look at the tools and technologies that were used to make this app, and for details, read the case study. Then you can decide whether you want to build the next great web app or become a rock star instead.

Speaking of stars, scientists have astonishingly figured out how to learn about light from every star that ever existed. Researchers used the orbiting Fermi Large Area Telescope to look at distant galaxies and measure photons from various places around the universe. This data goes back to the formation of the first stars more than 13 billion years ago.

Finally, back on our own planet, you might have noticed that Google Maps recently added more building footprints to map displays. In case you didn’t count them, over 25 million new building footprints have been added to both desktop and mobile versions of Google Maps. Maybe you’ll see the new footprints while exploring your favorite city this weekend.


On Fridays we detour slightly from our usual posts and publish a Fridaygram, a fun compilation of nerdy stuff to amuse you (and us). And how cool is it that we have orbiting telescopes?

Seems like every few days, Google+ adds a new feature or three. Sometimes the features are small and useful, and sometimes they’re very cool – like the new YouTube playlist feature that automatically finds music from your favorite artists on YouTube and plays it.

Part of the fun of this feature is how easy it is to use. From your Google+ page, mouse over the YouTube button at the top right, click in the box that slides out, and type the name of an artist. Just like that, you have a YouTube playlist from the artist you chose. You can +1 the videos or even share them back to your circles. It’s low friction and very handy.


Not all sounds are pleasant, and one of the worst is that old classic, fingernails on a chalkboard (did you just shudder?). Because science is awesome, scientists have studied exactly what makes this sound so awful. It’s not the high-pitched screech, they found: it’s the mid-range. They think it’s because our ears have evolved to be sensitive to those sounds. And watching it done makes it sound even worse.

Finally, while you’re enjoying your weekend, take a moment to go to google.com and search for do a barrel roll. This one is extra fun for you Star Fox fans.


Fridaygram is not the typical APIs and tools stuff we usually post about here. Instead, we find fun and cool facts and features to tell you about, from Google and other places. And I’m sorry about the screeching thing.

This year marks the 100th anniversary of El Ajedrecista, a very cool chess-playing machine that is credited as the first computer game. To celebrate El Ajedrecista and its creator, Leonardo Torres-Quevedo, Google and the Technical University of Madrid are holding a conference next week. This event will discuss Torres-Quevedo’s many inventions, which included a cable car that still runs over the Niagara Whirlpool and an arithmometer that could perform calculations.

The conference takes place on Wednesday, November 7th and features lectures and exhibits, including El Ajedrecista itself. If you’re going to be in Madrid, you can request an invitation. Note that if you play against El Ajedrecista, you’re going to lose: Torres-Quevado cleverly designed the machine to play an endgame from a superior position.

Speaking of moving pieces around, Angkor Wat is a huge temple complex, made from literally millions of massive sandstone blocks. Historians have wondered how ancient laborers moved these blocks to the building site. According to a new study reported by +LiveScience, the blocks were made in quarries and transported 37 kilometers via a network of canals. A previous theory suggested the blocks spent part of their journey going upstream in a river, but the newly discovered canals make the trip much shorter, and a shorter route is important when you’re pushing multi-ton hunks of sandstone around.

Finally, if you’re have some time this weekend, you can lose yourself in a bunch of new works available from the Google Art Project, including collections from Italy, Turkey, Peru, the U.S., and China. Beautiful.


Every Friday, we take a break from technical posts and publish Fridaygram, which contains stuff about science, history, the arts, and anything else cool and nerdy. And then pretty soon it’s Monday again.

Satellite images make the world seem smaller by letting us view images of buildings and neighborhoods that are thousands of miles away. The satellite views in Google Earth and Google Maps are updated periodically. Want to know when that happens? This week we added support for 43 more languages to Follow Your World, a web site that emails you when satellite images are updated for anywhere you like. Just enter a location and your email address, and you’ll be notified when a new aerial image is available.

Back on earth, engineers at UC Berkeley’s Biomimetic Millisystems Lab have an awesome job: they get to build little robot bugs. Recently, the team added wings to its 10-centimeter Dynamic Autonomous Sprawled Hexapod (DASH) robot to see how the alteration would affect mobility. The plastic wings helped DASH move faster and climb steeper hills, among other improvements.

Finally, here’s a tiny new feature: if you do a Google search for ip, you’ll see your computer’s IP address. Handy!

And also: check out today’s Google Doodle, which honors the birthday of Mary Blair, a Disney Legend known for her work on It’s a Small World and many other theme park and movie projects. (If you’re reading this after October 21st, you can see the Doodle on our archive page within a few days.)


Small explanation: Fridaygram posts are lighter than our usual stuff, meant to provide a little geeky fun at the end of the week.

Updated at 4:30 PM to say that Follow Your World added language support this week, rather than launching.

We have never said much about our data centers, but this week that changed in a very cool way. We launched a new site that takes you inside our data centers, with lots of great photos, a walkthrough courtesy of Street View, plus a WIRED story by Steven Levy about how our data centers have changed since the earliest days of Google.



Secret tip: there might be Easter eggs in the Street View tour.

Looking back a bit, about 250 million years ago, scientists have now figured out why there were no new species for 5 million years in the Early Triassic period. It turns out to be a simple answer: the weather was really hot. A study found that the average land temperature near the equator was 50 to 60°C, which was enough to keep new species from developing.

Returning to the present, this past week saw the final journey of the Space Shuttle Endeavour to its new museum home. This event provided some incredible juxtapositions as the spacecraft rolled down Los Angeles city streets past homes, restaurants, and onlookers. It was definitely not typical L.A. traffic.


The tagline of Google Developers Blog up there at the top is “News and insights on Google platforms, tools, and events”. This is somewhat less true on Friday, when we publish Fridaygram, a post containing stuff that’s simply interesting and nerdy.

We’ve posted before on Fridaygram about the Google Cultural Institute, which helps get historical material out of boxes and museums and onto the web for everyone to see. This week, the Institute added some really cool new exhibitions online that take you inside major historical events, such as color photos and personal memories of D-Day, the story of anti-Apartheid activist Steve Biko, and the 1953 Coronation of Queen Elizabeth II. These exhibitions features amazing photos, videos, and documents, and make great use of the web.



The planet 55 Cancri e is not receiving explorers or tourists at this time (as far as we know), but that might change once word gets out that some of the planet is made of diamond. 55 Cancri e orbits very closely around its star, completing a full circuit in just 18 hours. This close orbit raises the surface temperature to a balmy 2,100 degrees Celsius, so maybe hold off on those diamond-mining travel plans after all.

Finally, here’s a story to convince you that your dad and your mummy were right: brush and floss your teeth!


After a long week of writing code, and before a long weekend of writing code, take a pause to enjoy Fridaygram, which generally has nothing to do with writing code. And as a bonus for those who have read this far, here’s a tip on how to win a Nobel Prize: eat chocolate (and then brush).

If you’re a teacher, happy World Teachers' Day! Whether you’re a teacher or not, you might take a moment today to think of your favorite teacher, that one who made a big difference to your education and general life outlook. We support education in a bunch of ways, such as YouTube Edu, App Engine Education Awards, and Google Apps for Education. And recently we’ve been observing World Teachers' Day by recognizing a few amazing teachers on our +Google in Education page. Here on Fridaygram, we try to honor our teachers by using good spelling and grammar.

Savvy history and science teachers might have told their students that yesterday was the 55th anniversary of the Sputnik launch. Sputnik was the first human-made object to reach space. Sputnik looked like a basketball with antennas stuck to its side, and the little (585 mm diameter) spacecraft beeped its way around the world. Sputnik only lasted about 3 months in orbit, but it was a huge milestone.

Finally, here’s something that might prove educational: it's a video that shows how to flip food in a pan just like a pro. Spoiler alert: you’re supposed to move the pan back and forth, rather than actually trying to flip the food into the air. This will give you something to practice over the weekend.


All week long we post about important developer topics. Once a week, on Friday, we do a Fridaygram just for stuff that’s fun and interesting, but not necessarily developer-related. Special thanks this week to Boing Boing for showing off the food-flipping video.

The Dead Sea Scrolls were lost in the Judean desert for more than 2000 years before being rediscovered in 1947. Now The Digital Dead Sea Scrolls project makes five of the ancient documents available online to everyone.



The online scrolls contain incredibly high-resolution photography (up to 1200 megapixels) and an English translation along with the original Hebrew text. Looking through the scrolls online is a remarkable mashup of ancient artifacts and modern technology.

Not everything can be done online: sometimes you need to be there. When a magnitude 5.8 earthquake struck near Washington, D.C. last August, the Washington Monument suffered visible damage. This week the U. S. National Park Service sent its "difficult access team" to rappel up and down the monument to check for damage. Civil Engineer Emma Cardini seemed to enjoy the task and was quoted as saying "It’s really cool to see the planes flying under you". See, that’s why it’s great to be an engineer.

Birds fly, too – but dinosaurs with feathers? Check out this news from Canada about the discovery of amber-bound feathers that belonged to dinosaurs and birds from the late Cretaceous period.


Fridaygram is a weekly post containing a cool Google-related announcement and a couple of fun science-based tidbits. But no cake.

If you’re making a map of the world, you have to pay attention to the large fraction of the planet that’s beneath the water. That’s why Google Maps now includes underwater panoramic images from around the oceans. Naturally, there are a lot of wonderful sights to see, including a sea turtle with a school of fish and an ancient boulder coral. And just for fun, you can watch an underwater hangout from the Great Barrier Reef, without traveling to Australia or getting wet.



We don’t know if Google Maps has yet captured an image of a vampire squid (Vampyroteuthis infernalis). But researchers have found that this creature, whose name means "vampire squid from hell", has been more than a little overhyped. The vampire squid doesn’t hunt victims for blood. Instead, it eats random detritus floating around in the ocean. Still: great name!

Finally, the people who operate the International Space Station have a lot to do, such as making sure it doesn’t plow into any space junk. With that excellent goal in mind, NASA was considering moving the ISS this week to avoid an old satellite and a piece of rocket in its path. How do you move the ISS? By firing the engines of a docked cargo ship, of course!


Fridaygram posts are mostly for fun, not necessarily for developer stuff like our posts the rest of the week. This week Google turned 14 years old, and like lots of others its age, Google is already learning how to drive.

Hackathons are a blast. There are few experiences better than writing code all night with dozens or hundreds of others, consuming free food, and converting that sweet sleep deprivation into creativity as you hack. As hackathons go, this one is spectacular: Hack4Transparency takes place in Brussels at the European Parliament. The goal of this event is to make data more accessible and intelligible to consumers and to government.


You expect food and WiFi at a hackathon. But this is really cool: if you’re selected to attend, the hackathon pays your travel and accommodation expenses, and a couple of the best hacks will win a prize of €3.000. If that got your attention, read the full story on our Open Source Blog, and then apply to attend.

When I was a wee hacker, I would sometimes break up my coding sessions with a primitive videogame called Pong. Physicists at Cambridge University are still playing this game, sort of, except now they’re knocking a single electron back and forth. As if that Pong ball wasn’t small and easy to miss enough already.

Finally, if you have some time this weekend and you’re not coding or playing video games, you can check out this excellent collection of sounds from spaceflights posted by NASA. You can even make them into ringtones, so if you want to hear a 50-year-old Sputnik beep when your friends call, go for it.
