I have a friend that works at a famous credit checking company in their data research team, here in Latin America. He told me that IBM's data service (ie Watson) was not at all impressive. At the time (about a year ago) their service w

Some people are anti-automation. I am an economist, turned into "data scientist" since I've learned to program in the past 5 years (hate that name...). At a macro consultancy firm I worked, everybody lost it when I suggested

I have read about what reddit does, but idk if it was a simple (or hashed) database lookup or maybe a BF.

So, which one do you use?

by in9 9y ago
Disagree.. A book could easily show you some basics for project/directory structure, basic code organization, documentation, simple defaults that can really make life easier for a noob. With that he can get used to it and compare code

How easy is it to embed custom D3.js visualizations with Dash?

by in9 9y ago
I think shinny is awesome, but for online dashboards for my company, Dash seems awesome for one reason: no R. :D Don't get me wrong, I use R almost everyday in my analysis, but setting up a dashboard that connects to a remote data sour

In my mind, the JS stack is not the most useful for a non programmer, and I'd go with python. It makes easy to have decent scripts/programs for office work (pandas + directory handling) imo

Something that I do now and then, that really screws up the readability, is when I want to join a dataframe with another, but forget to manipulate the second. And it turns to something like: df %>% select(var_1, var_2, var

Idk why, but looking at the traditional base-R functions really hurt my eyes. The inconsistent api (like in gsub, where the string comes last) together with the unclear naming (very Unixy when you think about it) made it very hard for me wh

it is quite simple in pandas, but as a said in another comment, your example is a bit weird, since it turns all values of x into the same. But this is how to do it: df.assign(x = lambda x: x.ix[2, 'y']).query('x > 3')

If you are not using indices and multi-indices you are missing out in the awesome advantages in using pandas. If you come from an R background, indices (or rownames in R) are a real hassle, and you always want to keep them in columns. But i

by in9 9y ago
This example seems a little odd, since it takes a data frame and mutates the x column to be equal (all entries of the column) to the sum of the second component of the y column/vector to the 3rd component of the z column/vector. I

I didn't even read the article, but I agree with the title already. The amount of companies asking for knowledge in Hadoop for data only bigger then excel limit is not trivial... At least in the area where I work, this is the case

His second channel is very nice as well. More casual and conversation based, and a bit less interesting on the topics it self. But nice nonetheless
