Bing + Alpha Even better!

Few months ago, I blogged about a niche new search engine Wolfram Alpha is serving and its product positioning within that space. Turns out, Wolfram Alpha and Microsoft management is moving into exactly that direction. Microsoft's Bing is licensing technology from Wolfram Alpha to serve niche results. This is even better! Now Wolfram Alpha is getting mainstream traffic and serving outstanding search results within its special niche, while bing will serve most other results. This is win-win case for brilliant technology of WFA and promising counter attack by Bing...

is facebook defying gravity?

Social networks usually have a very strong network effects. Meaning, I don't give a damn about ANY social network unless I have my friends/ family on the network. So I would not care about facebook otherwise, but since most of my friends are on facebook, I am on facebook and vice-a-versa. (Ok you can imagine other example of network effects, eg. Phone! I have a phone because other people have a phone and I can call them! ok enough of being pedantic..)

IMHO, establishing a new product by breaking these network effects is as good as defying gravity. I'd not put my money on such product/ service. But it's apparent to me that facebook is eventually going to beat Orkut in Indian market. Not long ago Orkut was the norm. Everybody is/ was on Orkut in India. But something happened, and suddenly people are moving to facebook. In my small test sample of my own friends, I have added 100+ friends on facebook in last 2 months who also happen to be my friends on Orkut. I have over 20+ wall posts on facebook, and have just under 5 'scraps' on orkut...

What you think? What could be the reason behind this kind of abnormal phenomenon? What is the secret sauce facebook have that orkut doesn't? After all, orkut is a Google venture!

Update: !so Google - Orkut's response to stop the exodus to Facebook - stor from tech crunch

Digitizing Books One Word at a Time

UPDATE: Google buys ReCaptcha | official one

Original Blog
Continuing my curiosity with CAPTCHA's, I came across this amazing initiative here.

This project involves digitizing books using solved CAPTCHA's. Over 200 million CAPTCHA's (words) are decoded by real people everyday. So this novel idea involves using this effort to convert books into digital books. In the past we have used OCR (Optical reader) software. But OCR's are not accurate enough. Combining OCR + human intelligence with CAPTCHA's is a killer idea!

Similar efforts were implemented by Google to improve its image search results called 'Google Image Labeler'. But reCAPTCH project is taking social human intelligence to the next level.

What can be other ideas of using human effort to make meaningful contributions? Few ideas I can think of are - music tagging, video tagging, using spelling mistakes as a feedback to spell checkers.... What else? Any suggestions?

Kai Fu Lee and doing web business in China

Last week Google China VP Dr. Kai Fu Lee left Google to start his own venture capital firm to back China based high tech innovation. Last year as a student at Carnegie Mellon University, I had a chance to listen to his interesting lecture on Google's China strategy. I highly recommend watching his full lecture to anyone who is interested in understanding China's technology landscape, and how it is different. He shared some very interesting observations like -

In China - people do not have access to Wikipedia!
It is belied that to be successful in China one needs to take long term view, Google fully understands this -

"We will take long term view in China, China has 5000 years of history and Google has 5000 years of patience in China" - Google CEO, Eric Schmidt

Finally, the way Chinese users view a search page is far different than the way americans do - here are the results of an eye tracking study of a Goole search page!

Here is the full lecture -

Solving maths problems using Wolfram Alpha

Recently, I won a maths challenge (ok, I am kidding... but anyways), and the secret sauce behind my quick problem solving ability was - Wolfram Alpha.



Lets look at how it solves some complex high school maths problems -
1. Find LCM (least common multiple of 5, 21, 87) = LCM(5,21,87) = answer

2. Remember quadratic equations ? Lets give it a try, solve 3x^2 + 6x -15 = 35
3. Moving on - solving linear equations? Lets try to find values of x, y and z from following :
7x + 8y - 3z = 80, 2x - 3y + 4z = 35, 6x + 2y + 3z = 50 - here is the answer
4. Finally, (I was lost by this point) - remember chain rule for solving differential equations ? Lets try differentiating (4x + x ^ -5) ^ 1/3 and the answer (Tip: All steps included)

Btw, here is complete list of examples. Wish I had this cool tool when I was in school - and the case for not having one, and a smart get away.

Entrepreneurs

Last week two of my friends launched their own businesses - this blog is a tribute to their promising ventures -

My Carnegie Mellon friend Ankush Gupta - recently launched his venture Vigyaapan technologies - a targeted advertising product focused on leveraging social networks. Unlike most ventures of ad-targetting on social networks, Vigyaapan is building product based on social connections (network) formed over a "phone" network.. His venture was also featured under "top 10 hottest start ups" in India.


My high school friend Vipul Shah has also launched a very promising business - Trias Advisory - Firm aimed at providing financial advisory solutions. Vipul and his partners hold an MBA from reputed institutes and vital experience in wealth and financial management.

So, if you want to market your product, contact Ankush, or if you are rich and need a new and promising money manager contact Vipul. My best wishes to both these ventures...

Miles Miles Miles

If you are a "semi frequent" flyer - or a frequent flyer but not really loyal to an airline - there is a good chance that you will end up with "miles" way away from 20000 or 25000 miles required to get your free round trip.. This is your dead beast - essentially of no use but the savings number. Recently I figured out a way to use this dead beast rather meaningfully -

It turns out we can subscribe to many news papers and magazines at relatively cheap miles! Here is a quick summary of what you can get for round trip miles that you have earned on your last NY-SFO flight...

Fortune Magazine for 12 Months (1200 Miles)
Forbes Magazine for 12 Months (1400 Miles)
Wall Street Journal (Daily) for next 8 Months (2600 Miles)
Barrons for 12 Months - (1200 Miles)
Your Local news paper for 2 Months (600 Miles)
Econmist (51) - 3100 Miles

I guess thats an impressive list - if you are one like me - who loves reading all these business articles - and specially in a print format this is a free treat with your dead miles - Enjoy!

(Btw, now you know secret behind my daily wall street - Also eventually no one is going to pay any money for this - you can read this case here)
