This week we announced Project Loon, a cool and kind of crazy project that launches Internet-connected balloons and shares their connection with people below on Earth. These are not your typical birthday balloons: they’re 15 meters wide, and they rise to an altitude of 20 km, where winds carry them around the world. Software computes where the balloons should go to provide the best network coverage, and the balloons are then steered and moved as necessary.



Sailing along in the stratosphere is an essential aspect of Project Loon. The stratosphere is far above general air traffic and weather, so Loon balloons don’t have to worry about that. On the other hand, the environment is not friendly, with thin atmosphere and -50°C temperatures. But because the balloons are designed for these conditions, they can survive happily.

Moving further away from Earth, all the way to deep space, astronomers have found 26 new black holes right here in the neighborhood, in the Andromeda galaxy next door. Scientists using the Chandra X-Ray Observatory detected the black holes by observing telltale bursts of X-rays as the black holes ingested the outer atmosphere of ordinary stars. And this is just the start: there are likely thousands more black holes in Andromeda. So if Internet balloons ever make to Andromeda, we now know some places to avoid.

Finally, if you’re looking for something fun to do this weekend, you can spend time with a trio of nifty Chrome Experiment games released over the past couple of weeks: Roll It is a classic boardwalk game with the modern twist of using your mobile device as a controller, Racer builds a race track and soundtrack from several mobile devices put together, and Cube Slam lets you play an old-school arcade game over the Internet with friends (and if you have no friends, you can play against a virtual bear). Have fun!


From distant galaxies to ursine videogame opponents, Fridaygram rolls wide and deep. We cover fun stuff that isn’t always directly related to writing code, just in case you need an end-of-week break. If you’re having too much fun with our trio of games and you want to learn something instead, you can read about how we built each of them: Roll It, Racer, Cube Slam.

Did you notice the new Interactive Transcript feature that lets you scan quickly through the full text of any owner-captioned video that you’re watching on YouTube? For videos from I/O, that means you can quickly scan through a 60 minute talk to find just the part of the talk that you need to see. Or use your browser search with the Interactive Transcript to find a mention of an API call, and then click on a word in the transcript to jump straight to that part of the video.

Because developers don’t all speak English (and because some developers speak really fast when presenting) we caption every video that we post to http://www.youtube.com/googledevelopers. Most of the year, that’s a pretty easy thing to keep up with. But last year, when we posted all the videos for Google I/O 2009, it took us months to get everything done.

This year, we captioned everything within 24 hours or less of the videos going live. I’m excited about that, because it wouldn’t have been possible without the new auto-caption and auto-timing features in YouTube. We also did something a little nerdy -- we used four different methods of captioning.

If you use YouTube to share talks from your own developer events, you might find this summary useful.

The two fastest options for producing and cleaning up our captions used auto-timing. We uploaded a transcript and had YouTube’s speech recognition calculate the timecodes for us.

The two auto-timing methods were:

• CART live real-time transcript + auto-timing
  Because we had professional real-time transcriptionists at I/O, we could instantly caption anything that had a live session transcript. That’s how we got the keynotes captioned on the day of the event. We also used this method for the android talks.

• Professional transcription + auto-timing
  This was less expensive than CART, and faster than full captions with timecodes, but slower than real-time transcription because we had to get video files to the transcribers.

Although these methods were fastest, auto-timing turned out not to be perfect for all videos. When mic quality varied, or we had too many speaker changes in a short period of time (e.g panel discussions or fireside chats), the timing sometimes slipped out of sync. You can still use the Interactive Transcript to see what was said, but it’s not ideal.

The two slower methods that we used were:

• Pure 'traditional' captioning
  This is what we did last year for Google I/O 2009 videos. It’s slower, and more expensive, because you have to transcribe and set all the timecodes correctly. But the end result is 100% accurately timed. We did this to fix a video that the auto-timing had a lot of difficulty with.

• Speech recognition (auto-captions) with human cleanup and editing
  This gave us perfect timecodes, just like traditional captions, and took less time than traditional captioning. It took slightly longer than auto-timing alone because we had to download the machine-generated auto-captions from YouTube to do the edits.
  
  Automatic captions are fantastic if you don't have time or budget to put any work into your captioning. But for I/O, we wanted our captions to be perfect on technical terms, so fully automatic captions weren't the best fit.

Not all of these methods are equal in terms of quality, but it’s interesting to compare. To see which method was used on a video, look for the track name in the caption menu. To compare owner-uploaded captions with pure machine-generated auto-captions, you can always choose ‘Transcribe Audio’ from the caption menu for our videos.

If you’d like to help improve caption quality, please watch a video and fill out our caption survey to tell us what you think of these captions! We know some of them are going to be a little off -- if you report issues, we’ll fix them.

salam every one, this is a topic from google web master centrale blog:

Webmaster level: All

To help webmasters manage the verified owners for their websites in Webmaster Tools, we’ve recently introduced three new features:

• Verification details view: You can now see the methods used to verify an owner for your site. In the Manage owners page for your site, you can now find the new Verification details link. This screenshot shows the verification details of a user who is verified using both an HTML file uploaded to the site and a meta tag:

  

  Where appropriate, the Verification details will have links to the correct URL on your site where the verification can be found to help you find it faster.

• Requiring the verification method be removed from the site before unverifying an owner: You now need to remove the verification method from your site before unverifying an owner from Webmaster Tools. Webmaster Tools now checks the method that the owner used to verify ownership of the site, and will show an error message if the verification is still found. For example, this is the error message shown when an unverification was attempted while the DNS CNAME verification method was still found on the DNS records of the domain:

  

• Shorter CNAME verification string: We’ve slightly modified the CNAME verification string to make it shorter to support a larger number of DNS providers. Some systems limit the number of characters that can be used in DNS records, which meant that some users were not able to use the CNAME verification method. We’ve now made the CNAME verification method have a fewer number of characters. Existing CNAME verifications will continue to be valid.

We hope this changes make it easier for you to use Webmaster Tools. As always, please post in our Verification forum if you have any questions or feedback.
