A recent training I created and gave



Coursera is not a MOOC

Consider the hypothesis above and consider the facts below

massive open online course= Mooc

but coursera is not Open


  1. You cannot share Coursera content on Youtube or any non Coursera- this effectively ties in people to the website
  2. The Website does not use any social login or OpenID
  3. There is enough evidence of cross selling including branding, selling books and now 50$ certificates
  4. There is more vigor to get easily monetization course curriculum than to get subjects that are relevant to society ( eg job training for laid off workers in rural USA or for farmers in Africa or for textile mill workers in Bangalidesh)
  5. No effort in localization and customization or translation despite multiple avenues for machine learning enabled translation APIs (cough cough Machine learning= ML)
  6. Prof ML insists on using Octave and not R. Everyone knows Sheldon Cooper is more cool than Howard Wolowitz, yet Prof  ML  will say – it is easy to prototype using the latter and not the former. Plus he does not really update his slides too much
  7. With a 5% pass rate you actually dont care about the (students) education as they are just (money) bricks in your (fire) wall
  8. Blog posts are shared but data on usage and engagement is not shared openly or through an API
  9. Lame efforts at open sourcing the platform
  10. Lamer efforts at keeping clutter off the course search page ( Hint- Dont use Ctrl + F)

Revolution Analytics likes FOSS and becomes seriously awesome

and I mean Free and Open Source (FOSS not Fuss)

Hopefully teachers in academia can start using the flavor of R that will help their students get more jobs

Hopefully analysts in industry can start using this flavor of R without worrying on costs or vendor lock in

It’s all here folks and its seriously awesome

How to be a good blogger

1) Be Honest. Internet and Google are good at recognizing fakes

2) Always keep an eye on web analytics to receive feedback on what works and what does not work

3) Categories and Tags help people and search engines find your content easily

4) Trust in God but use Spell Check.

5) Interesting blog beats non interesting blog

6) Curiosity and Utility are the two things you need for a blog.

7) Artists steal. Bloggers get inspired. Search Engines catch thieves. So modify when you get inspired. Use original words

8) Benchmark with the best blogs in your subject. Read others. What does your blog aspire to do?

9) People who know CSS and HTML are better at changing blog layouts. Or people who are better at finding WordPress themes.

10) Plan your writing and always a few drafts handy.

11) Be regular in your passion for blogging. If you are not passionate about doing a good job out of it, you will NOT do a good job out of it.

12) Okay I have a superb blog. Where do I publicize without looking like a spammer?

Workspaces in Delhi and NCR – Social Offline

By DecisionStats Research Team

Workspace is an exciting concept and gives one an opportunity to work – away from home and collaborate, brainstorm, network and socialise. We are visiting workspaces this month and the following one and will be presenting a series of reviews to our readers. The first one is Social Offline that we visited on the third Tuesday of September this year and here is the review:

SOCIAL OFFLINE’S intent is connecting people offline while they are online. They come with three different offerings: Workspace, dining and bar. The Workspace and the dining restaurant operate during the day and the bar after working hours. The place is in the sideways of Hauz Khas Village in Delhi. The entry to the place is different and interesting. A graffiti alley leads you to a security check and then inside of it. The place has rustic interiors with wooden furniture, red brick unplastered walls, dim lighting with hanging bulbs from the ceiling and low volume music. It is spacious with two floors. The ground floor lounge hosts some workspace and a restaurant. The first floor is all about the workspace with a conference room and a balcony. As a workspace it offers a casual ambience, intending it to be fun though, wherein an individual can come daily at a chosen workstation or a different desk everytime and work. One can find all kinds of people here, entrepreneurs, freelancers. startup individuals, artists, work from home individuals. It offers an individual all the facilities of an office – internet connection, air conditioning, power back up, conference room with whiteboard and projector, food and drinks. The space is limited to 50 seats with a fee of INR 5,000 a month for 1 seat and that can be redeemed for food and drinks. One can apply online for a workspace and maximum two seats are allowed for a team. The selection process is little rigorous as management has its own criteria based on the profile of the applicant and some other considerations.

And about the food, the place offers a variety of food and drinks with its own unique presentation style – army plates, some of the drinks in pickle tumblers etc. The menu card is in the form of a rolled newspaper placed in a cutlery holder with a roll of tissue paper. We ordered one veggie sandwich which had four servings nicely packed on top of each other giving the sandwich a skyscraper frame. This presentation did bring a smile over our faces. The salads we ordered had veggies with semi-boiled eggs in it but could have been better if there had been an option of only veggie salad as well. The food menu was different on the two floors with fewer options on the first floor. We found the price of food a little on a higher side while drinks we have heard are reasonably priced, we didn’t try them though.

The plus point about the place for those who want to consider it as a workspace is its casual feel and the view from its balcony, which overlooks some greenery and gives the feel of a hill station. But the negative point is that the balcony is a smoking zone as well which might thwart some to enter there and enjoy. Also the dim lighting across the entire space gives Social the mood and feel of a bar and not the work ambience. For us the right work ambience will be more lighting, little more seriousness in terms of ambience, people’s speech volume and a smoke free balcony.

Social Offline as an experience does deserve a one-time visit and an exploration. And I am sure readers can then make a choice of future visits based on their preferences and likes.

Social offline has three branches – Delhi, Mumbai and Bangalore and the workspace timing is 11am to 6 pm (Monday to Friday). This place also holds art exhibits, comic acts, in-house and guest DJ events. Website:,, Address (Delhi): 9A & 12, Hauz Khas Village, New Delhi -110016, Phone: 07838652814
