Indian Business Schools Alumni try to grow more equal

A message from one the IIM (Indian Institute of Management) alumni networks, just an example of how any global organization should make extra efforts to make things more equal- and (thus position their brand for a differentiated place for attracting talent)

http://en.wikipedia.org/wiki/Indian_Institutes_of_Management

The Indian Institutes of Management (IIMs), are graduate business schools in India that also conduct research and provide consultancy services in the field of management to various sectors of the Indian economy. They were created by the Indian Government[1] with the aim of identifying the brightest intellectual talent[1] available in the student community of India and training it in the best management techniques available in the world, to ultimately create a pool of elite managers to manage and lead the various sections of the Indian economy.

The IIMs are considered the top business schools in India.[3] All the IIMs are completely autonomous institutes owned and financed by the Central Government of India. In order of establishment, the IIMs are located at Calcutta (Kolkata), Ahmedabad, Bangalore, Lucknow, Kozhikode (Calicut), Indore, Shillong, Ranchi, Rohtak, Raipur, Trichy, Kashipur and Udaipur. (My alma mater is Lucknow)

 

IIMs being role models have shared knowledge and skills with other institutions to improve their quality and standards in management education


————————————————————————————————————–
IIM A Alumni Association has been reaching out to the alumni associations of other IIMs to broad base the brotherhood (no offense to the fairer sex. Couldn’t think of a replacement word).

IM Calcutta Alumni Association has been conducting a lecture series and has invited us for the next edition. The topic is “The Unlimited Person”

India’s ambitions today – particulary reflected in the Corporate Sector – are Unlimited. What mind-set does it take to realise these ambitions ? Minds that live in the past or in the future – as too many Indian minds do – limit themselves, their companies and their country.

This presentation gives several examples of our current average mind-set and talks about ways in which an unlimited mind-set can emerge, creating “The Unlimited Person”

The speaker will be IIM Calcutta alumnus Shashi Maudgal, Chief Marketing Officer of Hindalco Industries of the Aditya Birla Group. The date is Friday June 24th at Gulmohar at the India Habitat Centre . Time 7 pm.

We hope you will come for this lecture and benefit from Shashi’s experience and insights.

Calling #Rstats lovers and bloggers – to work together on “The R Programming wikibook”

so you think u like R, huh. Well it is time to pay it forward.

Message from a dear R blogger, Tal G from Tel Aviv (creator of R-bloggers.com and SAS-X.com)

———————————————————————————————————-
Calling R lovers and bloggers – to work together on “The R Programming wikibook”
Posted: 20 Jun 2011 07:05 AM PDT

This post is a call for both R community members and R-bloggers, to come and help make The R Programming wikibook be amazing:

Dear R community member – please consider giving a visit to The R Programming wikibook. If you wish to contribute your knowledge and editing skills to the project, then you could learn how to write in wiki-markup here, and how to edit a wikibook here (you can even use R syntax highlighting in the wikibook). You could take information into the site from the (soon to be) growing list of available R resources for harvesting.

Dear R blogger, you can help The R Programming wikibook by doing the following:

Write to your readers about the project and invite them to join.
Add your blog’s R content as an available resource for other editors to use for the wikibook. Here is how to do that:
First, make a clear indication on your blog that your content is licensed under cc-by-sa copyrights (*see what it means at the end of the post). You can do this by adding it to the footer of your blog, or by writing a post that clearly states that this is the case (what a great opportunity to write to your readers about the project…).
Next, go and add a link, to where all of your R content is located on your site, to the resource page (also with a link to the license post, if you wrote one). For example, since I write about other things besides R, I would give a link to my R category page, and will also give a link to this post. If you do not know how to add it to the wiki, just e-mail me about it (tal.galili@gmail.com).
If you are an R blogger, besides living up to the spirit of the R community, you will benefit from joining this project in that every time someone will use your content on the wikibook, they will add your post as a resource. In the long run, this is likely to help visitors of the site get to know about you and strengthen your site’s SEO ranking. Which reminds me, if you write about this, I always appreciate a link back to my blog

* Having a cc-by-sa copyrights means that you will agree that anyone may copy, distribute, display, and make derivative works based on your content, only if they give the author (you) the credits in the manner specified by you. And also that the user may distribute derivative works only under a license identical to the license that governs the original work.

———-

Three more points:

1) This post is a result of being contacted by Paul (a.k.a: PAC2), asking if I could help promote “The R Programming wikibook” among R-bloggers and their readers. Paul has made many contributions to the book so far. So thank you Paul for both reaching out and helping all of us with your work on this free open source project.

2) I should also mention that the R wiki exists and is open for contribution. And naturally, every thing that will help the R wikibook will help the R wiki as well.

3) Copyright notice: I hereby release all of the writing material content that is categoriesed in the R category page, under the cc-by-sa copyrights (date: 20.06.2011). Now it’s your turn!

Tor Browser Bundle

The Tor software protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, it prevents the sites you visit from learning your physical location, and it lets you access sites which are blocked.

The Tor Browser Bundle lets you use Tor on Windows, Mac OS X, or Linux without needing to install any software. It can run off a USB flash drive, comes with a pre-configured web browser, and is self-contained. The Tor IM Browser Bundleadditionally allows instant messaging and chat over Tor. If you would prefer to use your existing web browser, install Tor permanently, or if you don’t use Windows, see the other ways to download Tor.

Freedom House has produced a video on how to find and use the Tor Browser Bundle. If you don’t see a video below, view it at Youtube . Know of a better video or one translated into your language? Let us know!

 

 

 

and if you now want to see or check your own website for a Denial of Service attack , download this

http://sourceforge.net/projects/loic/

This is the software for which 32 Turkish teenagers got arrested for bringing down their govt websites. Do NOT USE it for ILLEGAL purposes,

because 1) it is hosted on a western website that due to Patriot Act would tracking downloads as well as most likely be inserting some logging code into your computer (especially if you are still on Windows)

2) Turkey being a NATO member got rather immediate notice of this – which makes it very likely that this tool is compromised in the Western Hemisphere. You can probably use this in Eastern Hemisphere country excluding Israel, Turkey, China, India ,Korea or Japan because these countries do have sophisticated hackers working for the government as well.

3) This is just a beginners tool to understand how flooding a website with requests work.

http://sourceforge.net/projects/loic/files/

Basically download, unzip the file

Enter URL and click Lock on to know IP address.

use HTTP Method. Make say 1000 threads.

Then press the IMMA CHARGING MY LAZER big button.

Note the Failed Tab tells you how good or bad this method is.

Note – it wont work on my blogs hosted on wordpress.com- but then those blogs had a root level breach some time back. It did work on both my blogspot and my tumblr blogs, and it completely shattered my son’s self hosted wordpress blog (see below)
