Chromium OS Ported To The Nexus 7

Liam McLoughlin (most famously known as Hexxeh) managed to successfully port Chromium OS (the 100% Open-Source version of Chrome OS) last week on the ever-so-popular Nexus 7 tablet from Google. The build itself is not necessarily stable, but it’s still good news alongside Canonical’s release of the Ubuntu Installer for the Nexus 7  a few days back.

 Hexxeh uploaded a video showing his port and to be honest, it’s pretty cool. Check it out for yourself below:

how big is google's database

 Have any one have ever wondered hw big is the google's database.we would have searched 1000's of times in google and you even wonder .wow wat ever i search there is a lot google has lets see hw big is the google's database..

The Terabyte is a multiple of the unit byte for digital information. The prefix tera means 1012 in the International System of Units (SI), and therefore 1 terabyte is 1000000000000bytes, or 1 trillion (short scale) bytes, or 1000 gigabytes. 1 terabyte in binary prefixes is 0.9095 tebibytes, or 931.32 gibibytes. The unit symbol for the terabyte is TB or TByte, but not Tb (lower case b)

Google search crawler uses 850 TB of information, so that’s the amount of raw data from the web.

Google Analytics uses 220 TB stored in two tables: 200 TB for the raw data and 20 TB for the summaries.

Google Earth uses 70.5 TB: 70 TB for the raw imagery and 500 GB for the index data.

The second table “is relatively small (500 GB), but it must serve tens of thousands of queries per second per datacenter with low latency”.

Personalized Search doesn’t need too much data: only 4 TB.

Personalized Search stores each user’s data in Big table.

Each user has a unique user id and is assigned a row named by that user id.

All user actions are stored in a table.

Google Base uses 2 TB and Orkut only 9 TB of data.

If we take into account that all this information is compressed. For example, the crawled data has compression rate of 11%, so 800 TB become 88 TB, Google uses for all the services mentioned before 220 TB.

It’s also interesting to note that the size of the raw imagery from Google Earth is almost equal to the size of the compressed web pages crawled by Google.


Although there is not much known about the true size of Google's database (Google keeps their information locked away in a vault that would put Fort Knox to shame), there is much known about the amount of and types of information Google collects.

On average, Google is subjected to 91 million searches per day, which accounts for close to 50% of all internet search activity.  Google stores each and every search a user makes into its databases.  After a years worth of searches, this figure amounts to more than 33 trillion database entries.  Depending on the type of architecture of Google's databases, this figure could comprise hundreds of terabytes of information.

Google is also in the business of collecting information on its users.  Google combines the queries users search for with information provided by the Google cookies stored on a user's computer to create virtual profiles.

To top it off, Google is currently experiencing record expansion rates by assimilating into various realms of the internet including digital media (Google Video, YouTube), advertising (Google Ads), email (GMail), and more.  Essentially, the more Google expands, the more information their databases will be subjected to.

In terms of internet databases, Google is king.

10 Google products you (probably) never knew existed

Google Takeout – No, this is not Google’s food delivery service (although that’d be handy), this is a tool which allows you to download an archive of your data from things like your +1′s, Google+ Circles, Contacts and Picasa Web albums.

Google Mars – While you’re probably familiar with Google Earth, Google Mars is a little less well known. However, what it lacks in notoriety it makes up for in in geeky coolness. It gives you the ability to check out spacecraft landing locations, crater depth and even comes with an infrared option.

Google Health – This is one of the (many) products Google launched that didn’t quite capture the imagination of the public as anticipated. It was designed to be a portal for all of your health and wellness information. This service officially shuts down on January 1, 2013.

Google SketchUp – Now, this definitely falls into the ‘incredibly useful’ category of Google products. Google SketchUp allows you to create anything in 3D from coffee pots to skyscrapers. Check out the community gallery for added inspiration.

Google Correlate – If you’ve been watching the new TV show starring Kiefer Sutherland called Touch you’ll appreciate this one as it allows you to find patterns within data samples. Oooh yeah, go get your geek on!

Google Sites – It’s surprising Google hasn’t done more with this in light of the self-publishing explosion of the last few years. If and when you do need a spot online to share content with a specific group, this is a decent option.

Google HotPot – With SO MANY food review and recommendation services in existence, this seems like an odd one to add to the Google bucket list. And although it sits pretty seamlessly on top of Google Places. But I don’t know anyone who uses it, do you?

What Do You Love? (from Google) – You may have heard about this one when it was launched a little while back but if you haven’t, it is worth putting on your ‘to-do’ list. On the back of the ‘interest graph’ explosion, this aggregates content relating to specified topics from across the Google product network.

YouTube Feather – A slight cheat here as we’re looking at a sub-product from the Google-owned YouTube product. While it was released in 2009, it’s still being trialed and this means you may not have come across it yet. In short, YouTube Feather is a ‘light’ version of YouTube that aims to take the strain away from your browser and internet connection.

Panoramio – A photo sharing community that invites people to share their pictures of the world mashed up over the Google maps tool.
