For most data scientists, a toolkit like scipy/matplotlib or R becomes so familiar that it becomes almost an extension of their own mind. When fleshing out an idea, we will just open up ipython, write a few lines of code, and display the plot on the screen to get ...

I've been hacking on Breeze lately, which is a scientific library for Scala which aims to replace Scipy. It's got a long way to go, but it's definitely a great library and one that I make significant use of. One of the great things about using the ...

Last week I gave a talk at Helpshift about Bayesian analysis of conversion rates, A/B testing and Bandit Algorithms. The slides are hopefully self contained and might be useful for others. You can view them here.

I was recently introduced to the scalaz-stream library by the excellent blog post Actors are Overly Nondeterministic. I decided to take a look at them, and I realize they have a lot to offer.

One of the cools things I noticed could be built with them is Clojure-style Agents. But ...

In the past couple of weeks, the excellent article A Fervent Defense of Frequentist Statistics has been making the rounds. The article makes some strong arguments in favor of using frequentist tools, since many of them are more computationally efficient than Bayesian methods.

However, the author makes a fundamental mistake ...

A lot of people believe that Bitcoin and other cryptocurrencies are a speculative bubble. Scott Sumner is a notable person who disagrees, and believes that Bitcoin may be rationally priced based on the low probability of high expected rewards.

Most of the arguments claiming BTC is a bubble are nonsensical ...

Actors are overly nondeterministic. Argues also that futures have the same property - somewhat of a counterpoint to a post of mine on the same topic. Overall an excellent article, and it makes me want to take a much closer look at scalaz-stream. The author has two other posts on the ...

Interesting, and unpleasant: Narratives of Racism in Delhi University. I've never been to Delhi, but I got the impression that Pune is not so bad. There certainly is some racism, but from what I saw the ...

If you are in need of mainframe computers in Aurangabad, you can go to this store only.

Feeling stuck in a rut? Does programming make you feel bored, staring at the ceiling, waiting for your code to compile? I was in that place too. But over time, I've learned a few tricks to spice up my life and make my code compile faster. But it's ...
