I wanted to know that is YSlow effective for any particular kind of web sites , for e.g. would it really help in data intensive sites.
And is there any way to test how much improvement (may be what grade it could bring up to) it can give before actually implementing the changes it suggests?
No, YSlow is not designed to improve data intensive, if you meant heavy Ajax; it's more for page load and consecutive loads of a given page, although there're 2 ajax rules.
If you run yslow on a page you can share the results via Twitter or Facebook, the generated link points to YSlow Scoremeter which allows you to play with each individual rule scores so you have an idea what changes to implement. e.g.:
YSlow grade C for http://www.cnn.com/ http://yslow.org/scoremeter/?url=http%3A%2F%2Fwww.cnn.com%2F&grade=C&ynumreq=0&ycdn=0&yexpires=0&ycompress=78&yjsbottom=75&yexpressions=88&ydns=50&yminify=90&yetags=45&ymindom=49&ycookiefree=55&ynofilter=55&yfavicon=90 via #yslow

Note
I barely have any knowledge on web development but got some idea.
What I'm doing
I'm trying to make a Rust program to scrape any link to a media in a website, like how JDownloader 2 does. Not required to find all media, just any media this is simple enough to get.
Problems
Resolving links to media (Blob, Data)
Site that result differently on browser to a single get request (I have some idea that this might need a web driver but I want to have least dependency as much as possible)
Question
How did JDownloader find these media so I can implement it in my crate? (Just enough information to get start)

I went through the online Falcor videos and tutorials and it sounds very interesting. I am trying to determine if this would be a good fit for our application needs. Somewhere in the presentation I heard that it is very well suited for fairly static application, meaning the data is huge but mostly static. In our case, the data is huge but also gets updated frequently. So, the question how Falcor works when the backend data gets updated frequently.
If data held in client memory becomes stale due to its server-side representation changing (e.g. two separate users manipulating the same part of the graph) then you'll need some sort of server-push-to-client event stream thingy to notify the client of changes so it can keep its data cache fresh.
To my knowledge Falcor doesn't have any built-in hooks for this sort of thing. That doesn't mean Falcor can't be used for dynamic data; most MVC framework have this caveat. Just something to be aware of.

click on it to see the data in nse website to know how data represents
Here I will not do your home work to select the features(attributes) but I can help you so that you can also select features:-
You can use Minimum-redundancy-maximum-relevance.
Do by choosing that features which are less repeating and giving giving high co-relation with output.You must google for more information about mRMR algorithm.

Google Translate. Bing Translate. You can add a widget. You can select "Spanish" and the page will translate to Spanish.
I do not want to user to have to select "Spanish". I want the page to load in Spanish automatically. Never mind why I want these things. They are necessary parameters.
You could start by looking at navigator.UserLanguage in javascript. It's not entirely foolproof, but it's a good starting point, and provided the users aren't messing with what the navigator object actually pulls (fairly easy to fake) it should give you a reasonably good start.....you don't really have what language(s) you're using on your page tagged, so it's sorta hard to provide specific help.

I was wondering what would be the best strategy to implement a badges system using asp.net mvc. The one that stackoverflow has is pretty interesting. What do you suggest?
I guess I need to clarify the question a bit. The problem would be the different criteria for earning every badges. How do make that logic extensible?
I'd do it purely in T-SQL, and set up a SQL job that runs periodically (Jeff did it using C#, and has a goofy system where it runs the process based on a page request).
Basicly, in your SQL Job, scan your member tables and calculate if anyone is qualified for a badge, if so, update the badge table(s).
Then in the front end, do a query to retrieve new badges for a member on each request.
