JSS launches special edition for GUI for #Rstats

I love GUIs (graphical user interfaces)- they might be TCL/TK based or GTK based or even QT based. As a researcher they help me with faster coding, as a consultant they help with faster transition of projects from startup to handover stage  and as an R  instructor helps me get people to learn R faster.

I wish Python had some GUIs though 😉

Sergey Brin is so funny

I searched for-

Ajay Ohri

About 97,600 results (0.37 seconds)

Then I searched for

Sergey Brin-

About 3,470,000 results (0.29 seconds)

30 times more pages in 30% less time. Huh!!!

Why show me 300,000 pages of results anyway—-

The point I am trying to make is why does Google have more than 3 pages to show in the default view-

wouldnt they save time, bandwidth and storage if they just show 3 pages for every search result and give more than 3 pages only for Advanced Search.

I personally like the high quality Number 7 ranked search for Sergey Brin-




becuase it is ranked 3 places higher than his own blog http://too.blogspot.com/

Meet Google’s new CEO

Larry Page
Co-Founder and President, Products

Larry Page was Google’s founding CEO and grew the company to more than 200 employees and profitability before moving into his role as president of products in April 2001. He continues to share responsibility for Google’s day-to-day operations with Eric Schmidt and Sergey Brin.

The son of Michigan State University computer science professor Dr. Carl Victor Page, Larry’s love of computers began at age six. While following in his father’s footsteps in academics, he became an honors graduate from the University of Michigan, where he earned a bachelor’s degree in engineering, with a concentration on computer engineering. During his time in Ann Arbor, Larry built an inkjet printer out of Lego™ bricks.

While in the Ph.D. program in computer science at Stanford University, Larry met Sergey Brin, and together they developed and ran Google, which began operating in 1998. Larry went on leave from Stanford after earning his master’s degree.

In 2002, Larry was named a World Economic Forum Global Leader for Tomorrow. He is a member of the National Advisory Committee (NAC) of the University of Michigan College of Engineering, and together with co-founder Sergey Brin, Larry was honored with the Marconi Prize in 2004. He is a trustee on the board of the X PRIZE, and was elected to the National Academy of Engineering in 2004.

and no coincidence but it reminded me of the Metallica video- Turn the Page. Forgive the Pun, herr Eric

Some slideshare.net presentations I really liked.

A tutorial on SEO and SEM-

Carole Ann Matignon deals with optimization and scheduling, rules in the…….NFL!



Carole, We are waiting for the sequel on  analytics on football and the beer game.

Social Media Screw-Ups

Social Media doesnt matter at all- Social Media matters a lot- Still undecided? Take a look

Slideshare is a great VISUAL interface on sharing content. I liked Google Docs embedding as well, but Matt Mullenberg and Matt Cutts seemed to have stopped talking. Mullenberg is going like Zuckenberg, not willing to align with Sergey Mikhaylovich Brin. or maybe they are afraid of Big Brother Brin. Google loves Java and Javascript (even when they are getting sued for it)- while Matt M  hates it- bad for RIA I guess.

Scribd also is a great way to share content- and probably is small enough for. WordPress.com to allow embedding

Thats the reason why I sometimes prefer Scribd for sharing my poetry to Slideshare and Google Docs. Also I like the enhanced analytics and the much easier and evolved interface for reading. Slideshare is much more successful than Scribd because it is open to sharing with everyone- scribd tries to get you to register …;)

(* Also see MIT’s beer game at http://beergame.mit.edu/ which is ahem different from Duke’s beer games).



Advertising Feed back Loop: Facebook and Adwords

In Systems design a feedback loop is something that measures the difference between expected and actual output and adds it back to the system to enhance it’s performance

For a better more accurate definition see http://en.wikipedia.org/wiki/Feedback

Here is how Facebook measures the satisfaction whether I got for an ad on my page- note fraudelent or systematic cheaters would be eliminated by the law of averages.

It places a very small thumbs up or thumbs down on an ad on right hand corner.

When I place a thumbs down on an ad ( note it shows only graphical ads)-it asks me why i didnt like the ad

Was it

1) Misleading
2) Offensive
3) Uninteresting
4) Irrelevant
5) Repetitive
6) Other- allows text mining of free form allowing subjective feedback.

However if I type say Business Intelligence on Google – I get the following


Open Source Ad on Pentaho at prime spot just above the results. Makes me wonder how much open source will spend.

Search Results-
Wikepedia entry usually at the top ( but no ads there*)

Search Optimization means SAS Business Intelligence is now fifth from top- which is the first mention of a BI vendor there ( Note cost to SAS is zero as you can see below). In the remaining top 4, two are similar http://www.businessintelligence.com and http://www.businessintelligence.co.uk as the title page tag remains more important than sheer consumer behaviour to Pagerank.

Right Column Sponsored Links ( These guys spend more money than SAS to be on the sponsored links and still end up in a less favourable ad page than in top vendor on search results page)-

1 http://www.brgglobal.com
2 SAP.com/India
3 IBM.com/cognos
4 http://www.BusinessObjects-India.com
5 http://www.softsmith.com
6 http://www.syncfusion.com/BizIntell
7 http://www.intelligententerprise.com/

(Note from Ajay*- A senior IIM Alumnus CK Prahlad (the first batch in fact) – first expounded the concept of core competence-

Now-what is Google’s core competence.
I believe that Google should simply donate all its information on wikipedia, and offer Google Knol to it- rather than just wallow in sunk cost theory or expect an immediate return from this transaction. It will get lots of goodwill- and maybe the Google Wikipedia Knol will take off.

Similarly sell Orkut to Facebook and just take the advertising and search functions to be combined in a seperate spin off called Google Search before Microsoft forces the Europeans and Justice department to do so.

Or continue to moon the giant.)

I didnt like the Adwords ads or the order they were in. But there is no way in Adwords for me to give feedback to it. Facebook listens. Will Adwords listen.
