I agree to what Hadley said in some ways. It takes a bit more time to get used to the [i, j, by] notation and I personally feels its unlike most of the R syntax. But I dont see that stopping me from using something as fast as data.table.

I should have mentioned you (arun_sriniv) as the co-developer of data.table! Thanks for all the hard work. And yes, memory usage will be interesting as that is the bottleneck when it comes to large dataset. I am working on something on those lines. Will post something soon :)

Not this again! The fact that the article shows only the under developed images (like the over crowded vehicle and the snake charmer) makes me sad. These articles and the tv shows have completely wrong images of india in their mind. You can argue why is it a big deal, but when you see the typecast running in all the articles these days it hurts mostly because it so far from the reality. I have not seen a snake charmer my entire life after staying in the country for 25 years! The problems he mentions might be true I dont have any experience but I bet its common and holds true for the entire outsourcing business.

Then why the india in the title?

Data.table package by matt dowle definitely deserves a mention! Its fast and I like the indexing functonalities it provides. The benchmark timings are pretty impressive.

I use ijulia which is based on python notebooks. Try juliabox.org which is a notebook (and more) offering by the julia folks. Then there is juno and julia studio if you are inclined towards an rstudio like interface.

Ofcourse you can! I dont know why I didnt think of that

google photos is pretty neat and space expansion is not expensive either

you mentioned questions on scalability et al, answers to those questions are very subjective. I went through a similar experience at one of the biggest tech giants out there ... went something like this - i was in the final face to face interviews and did well in all of those IMHO. It was a big interview day at the company and lot of candidates flew in all over the globe. So all interviews done, we went for lunch in the cafeteria, and before I started I was called for another round of interviews (and couple of other guys were called too). To be honest I hate lunch interviews, I think its cruel! But anyways, I was asked about design and scalability etc. and that was the last interview that day. After a few days I get a rejection email from the HR folks. I was in the same boat as you are today ...
