Google Buzz! Will it really Buzz?

by 2 Comments

Google has launched its latest in social networking Google Buzz. This puts Google in direct competition with the top shots like Twitter.

Our belief is that organizing the social information on the web — finding relevance in the noise — has become a large-scale challenge, one that Google’s experience in organizing information can help solve. We’ve recently launched innovations like real-time search and Social Search, and today we’re taking another big step with the introduction of a new product, Google Buzz.

From Google Blog

Now the million dollar question that arises is, will it really buzz? I don’t have the answer as I am still waiting for my account to be activated with buzz. But I tried it on my iphone and was not too impressive. Will use it more and comment again here! Will appreciate your comments.

Google Apps: latest updates

by 3 Comments

Today google announced that in last 1 week they have upgraded google apps with the following two services:

  1. Upload any file to Google Docs
  2. Default https access for Gmail

As I extensively use google apps both of these features were something that I was really waiting for. I used to always wonder why it is not https by default and finally they made it. Following are the key features of the new additions as mentioned on google blog:

Upload any file to Google Docs
Last Tuesday, we began rolling out the ability for you to upload any type of file to Google Docs, not just documents, spreadsheets, presentations and PDFs. This lets you access and share anything up to 250MB from the cloud. You get 1GB of storage for uploaded files for free, and you can purchase additional storage for file uploads. (Additional storage plans are coming soon for schools and businesses, too.)


Google Apps Premier Edition customers can also use the Google Documents List Data API to programatically add files to Google Docs, and purchase third-party applications so employees can sync files between their computers and Google Docs.

Default https access for Gmail
In the past, you had the option to always use https encryption in Gmail to help protect your data as it travels between your browser and our servers. After evaluating the trade-offs between security and latency, as of last week https encryption is now the default in Gmail.

If you trust your network’s security and want to disable always-on https for performance reasons, you can change your preferences in Gmail settings. Employees and students whose admins have not already defaulted their entire organizations to https will also see this option. The Gmail sign-in page will still always use https to help keep your password safe.

ENJOY the new updates to google apps!
