I have had the misfortune of working with Q. It's a very clever little language that could be a great platform for numerical prototyping. Unfortunately, it's hobbled by a terrible programming culture. The interpreter gives cryptic single-ch

They definitely have a physical effect, but does that effect 'treat' depression any better than, say, atropine? ( http://www.medicalobserver.com.au/news/antidepressants-vs-ac... ) The current understanding is that the difference between SSR

Regardless of whether anti-depressants are effectual, overprescribed, or totally useless: I think it's amazing that an article arguing the merits of a pharmaceutical treatment can be published without reference to any research. >But tha

Thanks for posting this. The quality of the comments here is otherwise sadly low.

You guys seem weirdly resistant on this, but can you please turn off the inline comments? Or at least provide a global option for keeping them off? It makes navigating the songs hard and almost none of the text is ever interesting.

Most of my data is too big for CSVs but too small to justify distributed storage. I use HDF5 with chunking and column compression. I think many other people in the sciences and finance also do this (along with using NetCDF).

I'm very curious to see (a) what sort of generative model they're using under the hood, and (b) how they do inference efficiently enough to not dedicate a cluster to each customer.

This is pretty close to what I'm doing for my PhD research-- it's an annoyingly hard problem! Travis will probably make smarter design choices than me, but my project has ended up being of limited use due to the non-obvious subset of Python

Their sidebar explaining IQ scores seems a little silly. I'd like to see a citations for average scores of Nobel prize winners. Also, who went back in time to administer an intelligence test to Mozart?

I hold his writing to a non-academic standard and generally enjoy it. I did, however, get very angry watching him give a lecture. He seemed so enamored with weaving a vague but sexy story that I don't think even he believed his own thesis.

I would like to ban the word smart from common discourse. It looks like it describes something, but actually masks the reality of the how someone can look 'smart' in a situation.

A doctorate in education is of dubious worth. As an academic field education research doesn't yet have the tools of structures to answer interesting questions. In place of rigorous theories there is currently a swamp of poorly verified or u

Very cool article. I have to admit I'm a little frightened of the bulk and complexity of the RPython translation pipeline. I'm not happy about the prospect of waiting an hour to learn my code runs afoul of poorly documented type inference l
