Breaking: Skype Is Down
Skype, the free web based software based telephone service, is currently down for many of its millions upon millions of users.
Early afternoon, mid-morning for those in the Pacific Time period, many Skype users started to complain via Twitter that their service wasn’t work. Shortly thereafter, the company, which has its network operated by a Luxembourg-based company called Skype Limited, addressed the concerns of its users in a tweet.
“Some of you may have problems signing in to Skype – we’re investigating, and we’re sorry for the disruption to your conversations,” the company tweeted, while adding later, “Our engineers and site operations team are working non-stop to get things back to normal – thanks for your continued patience.”
The last time Skype had an outage of this magnitude was back in 2007. The company was once a property of EBay, but the voice service company separated last year.
“When we had Skype, we knew we had a good product, but there were no synergies between us and them,” Ebay Chief Executive Officer John Donahoe said at a recent
conference.

Google Chrome’s Bundled Games
The first Chrome 10 Dev Channel build bundles two HTML5 games: Poppit and Entanglement. The two games are added to the new tab page even if you’ve previously installed other apps.
Some users will probably be surprised to see two games they didn’t install, so Google should inform users that the games were automatically installed. Chrome’s source code makes it clear that Poppit and Entanglement are installed for all operating systems, except for Chrome OS. Probably a better idea would be to recommend some apps based on the browsing history.

New revision history interface in Google Spreadsheets
The newer revision history interface in Google Documents is now also available in Spreadsheets. You can now see all of the changes that collaborators have made cell-by-cell.
How to access what’s new:
- To see the new interface, go to ‘File’, then ‘See revision history’ when editing a spreadsheet.
- Click on a time stamp in the right column to see what changes were made at a given time or use the arrow keys to quickly scan through many revisions.
- Changes are color-coded based on each collaborator, making it easy to tell what has been added or deleted.
- Time stamps are also improved in the new interface.
- The interface also batches revisions into groups of changes to make it easier to understand how a spreadsheet has changed over time. To see a finer-grained list of revisions, click ‘Show more detailed revisions’.

Going green at Google in 2010
At Google committed in building a clean energy future because we we want to be good environmental stewards, and because we think it makes business sense. We’ve had a busy year with our clean energy initiatives. Take look at our redesigned green website and this new video from the Google green team to learn more about the priorities we’re pursuing:
As we look back on 2010, we wanted to highlight what we’ve been working on this year to help build a more sustainable future—for Google, and the world.
- Greening our operations. We already have the most energy efficient data centers in the world, and use renewable energy whenever possible. This year we created a subsidiary, Google Energy LLC, to enable us to purchase renewable energy on the wholesale power markets and to help spur development in the sector.
- Flexibility in buying renewable energy. In February, the Federal Energy Regulatory Commission (FERC) granted Google Energy LLC the authority to buy and sell energy on the wholesale market, giving us the flexibility to procure renewable energy at competitive prices.
- 20-year green power purchase. Our FERC authority enabled Google Energy LLC to enter a 20-year green Power Purchase Agreement (PPA) in July to buy clean energy from 114 megawatts (MW) of wind generation at NextEra’s Story County II facility in Iowa (read more about how the deal is structured). By purchasing so much energy for so long, we’re giving the developer financial certainty to build additional clean energy projects.
- Developing green products and tools. Just a few weeks ago, during the the U.N. Climate Change Conference in sunny Cancun, Mexico, we launched Google Earth Engine, a new Google Labs product. Google Earth Engine is a technology platform that makes an unprecedented catalog of imagery and data available online in one place for the first time. It enables global-scale monitoring and measurement of changes in the earth’s environment. We’re particularly excited about the initial use of Google Earth Engine to support efforts to stop global deforestation. We’ve also been busy this year incorporating green features into our products—like Google Maps biking directions and adding Carbon Disclosure Project ratings into Google Finance.
- Investing in a clean energy future. To date, Google has invested over $100 million in clean energy. Google.org has already invested in several clean technology companies. We’ve also continued our internal R&D on renewable energy technologies (RE<C), substantially growing our engineering team. And this year, Google began making project investments that offer a solid financial return, and could have a transformational impact on the renewable energy sector.
- North Dakota wind farms. In May, we invested $38.8 million in two North Dakota wind farms that generate 169.5MW, enough to power 55,000 homes. It was our first project investment, and uses some of the latest wind turbine technology and control systems to provide one of the lowest-cost sources of renewable energy to the local grid.
- Offshore wind transmission. In October, we made a development stage investment in a project to build a backbone transmission line off the Mid-Atlantic coast. The project will put in place strong, secure transmission, removing a major barrier to scaling up offshore wind. When finished, the 350-mile line will connect up to 6,000MW of offshore wind energy—enough to serve approximately 1.9 million households!
It’s been a busy year at Google, and we believe the world needs better options in the future. As we head into the new year, we look forward to continuing our work to find and support innovative clean energy solutions.

Chrome OS Is All About the Missing Features
Here’s an interesting quote from Ted Power, a former designer for Google’s mobile web apps:
“Chrome OS could potentially mark a profound leap forward. For the first time, all the layers between the network and the computer have been removed. The device itself is of little consequence; you can ‘feel right at home’ from any networked device. Chrome OS isn’t so much about what has been added, but what has been stripped out; no more complicated file systems, software updates, etc.”
Paul Buchheit, the ex-Googler who created Gmail, thinks that the ideal design of a computer that acts like a local node of a global super-computer matches the design target of Chrome OS. “It should be relatively cheap and reliable, secure (no viruses or anything), zero-administration (I don’t want to be a sys-admin), easy to use, and fast.” Paul says that Chrome OS is unnecessary because iOS and Android devices meet the same ideal and there are already millions of devices that run these operating systems.
There are already millions of people who use Chrome and some of them would like to buy a computer that’s as fast as their browser. Mobile phones are not yet powerful enough to handle complex web apps, but that will change and, at some point, web apps will be indistinguishable from native apps. You’ll be able to use your favorite web apps from almost any device, but why not use a device that removes everything that’s unnecessary and slows you down?
Google Wave on Google Shared Spaces
What happens with all the Google Wave gadgets, now that Google Wave has been discontinued? They’re available in Google Shared Spaces, a small Google Labs project that helps you collaborate with other people by adding information to a gadget. You can add placemarks to a map, draw on the same white board, play Sudoku, create lists, find the best budget accommodation, brainstorm, create diagrams and answer to polls.
“Google Shared Spaces allows you to easily create a space with a collaborative gadget and a chat box in it. The gadgets are based on the Wave gadgets technology, so there are already more than 50 gadgets across different categories, like games, productivity, and event planning. Anybody can create a new space by going to the gallery and clicking on one of the featured gadgets. Spaces can easily be shared by just pasting the URL into a chat window, an email or a content sharing platform like Google Buzz or Twitter. And if you know a little Javascript, it is easy to get started building your own real-time, collaborative gadgets and create new spaces based on those,” explains Google.
Maybe Google Wave would’ve been more successful if it didn’t have so many complicated features and ambitious goals. Google Wave could’ve been the back-end technology for many cool web apps, instead of trying to incorporate all the use cases in a single interface.

Blogger Templates for Mobile Users
This year, Blogger’s team added so many new features that it’s difficult to count them: dynamic templates, comment spam filtering, a new way to manage comments, real-time stats, better post preview, static pages and so much more. Blogger is one the few Google products that have improved dramatically this year, after many years when it was neglected.
Since a lot of people use phones to browse the Web, it makes a lot of sense to add a mobile interface for Blogger and to create mobile versions for Blogger’s templates. There’s no mobile Blogger yet, but all Blogger blogs have a mobile version optimized for WebKit browsers. Just add ?m=1 to the URL of any Blogger blog, and you’ll get a simplified version that works well on an iPhone, Android phone and probably other phones that use a browser based on WebKit. Here’s an example: http://googlesystem.blogspot.com/?m=1.
Bloggers can enable the mobile version of their blogs, so that visitors are automatically redirected to this version when they’re using a supported mobile browser. This option is only available if you go to Blogger in Draft, click on “Settings”, switch to “Email & Mobile” and enable “Yes, On mobile devices, show the mobile version of my template.” This didn’t work for me, so you’ll still see the regular mobile version of this blog that uses a custom stylesheet.
Google says that the new feature only supports 12 existing templates (6 variants of the Simple template and 6 variants of the Awesome template) and that all the other templates will be rendered as the Simple template. The mobile version drops the sidebars and most of the gadgets, shows small excerpts from the posts on the homepage, hides the comment form (but you can still post comments), resizes images and videos, adjusts fonts and converts AdSense ads into mobile ads. Unfortunately, you can’t customize mobile templates, at least not yet.
Now Picasa Web Users, Forced to Link Their Google Profiles
Google tries to make Picasa Web Albums a little more social, but it’s not easy to convince users that this is a good idea. I posted in August that Google will link Picasa Web Albums with Google Profiles. On the surface, this is a minor feature, but Google didn’t manage to explain users why it’s important.
If you visit Picasa Web Albums, you’ll see a huge modal dialog:
“Together at last! Picasa Web Albums now uses your public Google Profile to display your name and profile photo on your albums and next to your comments. This will help improve your experience in two ways. First, the quality of interactions across Picasa Web Albums will improve as friends can see and recognize whom they are interacting with. Second, using multiple Google products will be easier because you can now update your profile in one place.”
It makes sense for Google to have unified public profiles that integrate will all services, but users may find this disconcerting. Why take away my hard-earned alternate username and change it with a number? Why not use a different number in the URL than the Google Profiles ID, like Google Reader does? Why associate my photos with a public profile that includes my name and my Google Buzz messages?
Custom usernames were useful and I don’t see why Google isn’t more flexible. You should be able to keep the existing username or at least pick an URL that can’t be guessed from your profile address.
Instead of trying to make profiles more flexible, Google decided to disable most of the features until you link your Google Profile. You can no longer share a photo, favorite a user, add a comment. If you still don’t like the new feature, you have the one-time opportunity to transfer your photos to a new account.
You can’t force users to use a new feature by crippling the other features and then expect them to like the new feature.
Here’s how a Google employee tries to address this issue:
the chief reason for this profiles change is because we want the vast majority of pwa users to have a quality experience with other pwa users. right now, its common for a pwa user to get a comment on a photo from another user, and have the comment be effectively meaningless because it was posted by ‘DJJazzyJeff01234′. we’ve heard from many users how this freaks them out, and makes pwa a scarier place. we think this makes for a low quality social interaction between users and does not cause further engagement.
the other main reason we’re doing this is to simply help users manage their google profiles better across multiple google products. the reality is that many of our users use several google products, not just picasa. the new model lets you manage your profile ONCE, and you’re done.
in the end, you still will have total control over what others see. you can set your profile to show your full name publicly OR simply opt-out of your name being found in search. also your profile won’t display any private information unless you’ve explicitly added it.
New YouTube’s Watch Later Feature
YouTube’s embedded player has a new feature that lets you add a video to a special playlist and watch it later. This only works for the videos embedded using the new iframe-based code.
After clicking on “watch later”, the video is added to your homepage, so you can quickly find it.
It’s not very useful for Read it Later or Instapaper fans, but everyone else will probably enjoy the new feature. What’s surprising is that YouTube doesn’t add the videos to the queue, which is “a list of videos to watch later in your session”.

Google Maps 5.0 for Android and Vector Graphics
Now Google Maps are built using vector graphics to dynamically draw the map as you use it. Building a vector graphics engine capable of achieving the visual quality and performance level you expect from Google Maps was a major technical challenge and enables all sorts of future possibilities. So we wanted to give you a closer look under the hood at the technology driving the next generation of mobile maps.
Vector graphics
Before diving into how Maps uses vector graphics, it may be helpful to understand how maps were created before. Previously, Google Maps downloaded the map as sets of individual 256×256 pixel “image tiles.” Each pre-rendered image tile was downloaded with its own section of map imagery, roads, labels and other features baked right in. Google Maps would download each tile as you needed it and then stitch sets together to form the map you see. It takes more than 360 billion tiles to cover the whole world at 20 zoom levels!
Now, we use vector graphics to dynamically draw the map. Maps will download “vector tiles” that describe the underlying geometry of the map. You can think of them as the blueprints needed to draw a map, instead of static map images. Because you only need to download the blueprints, the amount of data needed to draw maps from vector tiles is drastically less than when downloading pre-rendered image tiles. Google Maps isn’t the first mobile app to use vector graphics—in fact, Google Earth and our Navigation (Beta) feature do already. But a combination of modern device hardware and innovative engineering allow us to stream vector tiles efficiently and render them smoothly, while maintaining the speed and readability we require in Google Maps. Just try it out and see for yourself!
One map, many perspectives
Using vector tiles instead of image tiles gives Maps the flexibility to re-draw the same map from different perspectives using the same set of data. Zooming is one example of this at work. If you magnify an map image tile by 2x, lines such as roads and text would get twice as wide and appear blurry. As a result, we had to constrain Maps to 20 fixed “zoom levels,” each one twice as close as the last. Every time you zoomed in further, you’d need to download a completely new set of image tiles. It took time to load new data over a mobile data connection, and would fail when you lost your connection in a subway or large building.
With vector graphics, you no longer need to “round” to the nearest zoom level and then download all the tiles for that level. One vector tile has the underlying vector data (or blueprints) to draw the map at many different levels of scale. So when you zoom, the map stops when your fingers stop, and roads and labels always stay crisp. This same technique powers the new 3D map interactions: tilt, rotate and compass mode. Just like with zooming, Maps uses the same vector data to draw the map from any angle or direction as you tilt or rotate.
We can also display entirely new levels of detail that weren’t possible with flat image tiles. For example, in the 100+ cities where we have 3D building data, each building is drawn in 3D using a polygonal building footprint and heights for different parts of the building. And with tilt and rotate, you can see them from a variety of different angles.
Reading the map
Just like other map features, labels are dynamically drawn so they continue to face you and stay legible if you rotate the rest of the map or use compass mode. Maps also “chooses” the best labels to show you based on several factors. You’ll notice labels fade in and out as you interact with the map so that the most useful ones appear and the map never gets too cluttered.
Vector graphics also allow us to draw additional data on the map more clearly. For example, traffic or transit lines no longer block the labels beneath them. We can also draw the same map in different styles—like “satellite view” where the roads are translucent over aerial imagery, or Navigation’s “night mode” where a darker palette helps your eyes adjust quickly in the lower light.
Offline reliability
Vector graphics also enable another significant new feature: the ability to continue viewing maps even when you have poor—or no—network connections. Because each vector tile works across multiple zoom levels, it requires more than 100 times less data to view maps across all zoom levels than before, allowing Maps to cache much larger areas of the map on your device.
With this first version, Maps proactively caches map data for the places you use Maps the most—where you’re actively using it as well as places for which you search or get directions. Then when you’re plugged in and connected over WiFi, caching happens automatically. Near your frequent places, you’ll get detailed vector tiles for city-sized regions so you can see every road labeled. Further away, you’ll have less detail but will typically have towns and highways labeled for miles. We’re continuing to work on these algorithms, so you’ll see improvements over time.
Offline rerouting
With Google Maps Navigation (Beta), you’ll also see the benefits of additional caching with offline rerouting. This feature is only possible because Navigation caches not only map data but also data like turn restrictions for the areas surrounding your route. You’ll still need to be connected when you first start a trip to download and cache your route. But this way, even if you take a wrong turn after losing your connection, Navigation can use the cached data to get you back on your way. We will be rolling this feature out gradually over the next few weeks.
This is just the start, and we’re really excited about all the possible ways to use vector graphics technology for the next generation of Google Maps. So please stay tuned!
Update 12:43 PM: Tweaked the description of the difference between image maps zoom levels.
