Microsoft says Hotmail is now 10x faster. What do you think?

Posted: 03 Jul 2011 09:06 AM PDT

Windows uploaded a video on youtube a week back, and it tells about how the June 2011 version of Hotmail is 10x faster as compared to their prior version.

Check it out here:



But how did Microsoft manage to find so much extra speed in a service that’s been online for 15 years?
Three techniques were used: caching, preloading, and asynchronous operations. These are not new concepts, but the recent update to web technologies in modern browsers has made them much easier to implement and more useful for web-based services such as Hotmail.

Could any hotmail users give reviews for the same?

Help a 2nd year CSE student

Posted: 03 Jul 2011 06:15 AM PDT

Hello CEans!

I am a 2nd year(3rd semester) student in the CSE department at NIT(National Institute of Technology). I am very confused about some learning topics. My current technical knowledge is: C, C++, HTML(XHTML), CSS and Javascript. And I am also about to start learning Java, PHP, Python and C#.
Its my aim(or desire) to build some small apps for windows. I also want to contribute to community forums of microsoft like that for silverlight, etc. But building windows apps is my first desire. I googled it and found some techs like .NET, Visual studio, etc. I really don't understand what is this .NET!? And is visual studio needed to build the apps?? Can I use any programming language to code in Visual studio?? Lastly, could you please explain "Google app engine". What it is? Do we create apps and put it there???
I would request you to assume my tech knowledge zero about the questions I have asked. It would really help me greatly to understand.
Thankyou in advance:).

Why to become an entrepreneur?

Posted: 03 Jul 2011 05:07 AM PDT

I have been thinking constantly about this topic for a few monts. And I am sure most of you must have thought about it once in a lifetime. Can we mention reasons why/ why not should we try a hand at business?

For me? May be I want to have a small start up whether successful or not in next 10-15 years

Transformers : Dark of the Moon - Any Reviews?

Posted: 03 Jul 2011 01:01 AM PDT

I am sure there will be a lot of Transformers fans here.
The 3rd part of Transformers : Dark of the Moon was released recently.

The theme: The Autobots learn of a Cybertronian spacecraft hidden on the Moon, and race against the Decepticons to reach it and to learn its secrets.

Any reviews, engineers?
