- Teach Don’t Tell — what I think good documentation is and how I think you should go about writing it. Sample common sense: This is obvious when you’re working face-to-face with someone. When you tell them how to play a C major chord on the guitar and they only produce a strangled squeak, it’s clear that you need to slow down and talk about how to press down on the strings properly. As programmers, we almost never get this kind of feedback about our documentation. We don’t see that the person on the other end of the wire is hopelessly confused and blundering around because they’re missing something we thought was obvious (but wasn’t). Teaching someone in person helps you learn to anticipate this, which will pay off (for your users) when you’re writing documentation.
Trina Chiasson argues that data has arrived at the same threshold as coding: code or be coded; learn to use data or be data.
Arguments from all sides have surrounded the question of whether or not everyone should learn to code. Trina Chiasson, co-founder and CEO of Infoactive, says learning to code changed her life for the better. “These days I don’t spend a lot of time writing code,” she says, “but it’s incredibly helpful for me to be able to communicate with our engineers and communicate with other people in the industry.”
Though helpful for her personally, she admits that it takes quite a lot of time and commitment to learn to code to any level of proficiency, and that it might not be the best use of time for everyone. What should people commit time to learn? How to use data. Read more…
A new operator from the magrittr package makes it easier to use R for data analysis.
In every data analysis, you have to string together many tools. You need tools for data wrangling, visualisation, and modelling to understand what’s going on in your data. To use these tools effectively, you need to be able to easily flow from one tool to the next, focusing on asking and answering questions of the data, not struggling to jam the output from one function into the format needed for the next. Wouldn’t it be nice if the world worked this way! I spend a lot of my time thinking about this problem, and how to make the process of data analysis as fast, effective, and expressive as possible. Today, I want to show you a new technique that I’m particularly excited about.
R, at its heart, is a functional programming language: you do data analysis in R by composing functions. However, the problem with function composition is that a lot of it makes for hard-to-read code. For example, here’s some R code that wrangles flight delay data from New York City in 2013. What does it do? Read more…

- Data Portraits: Connecting People of Opposing Views — Yahoo! Labs research to break the filter bubble. Connect people who disagree on issue X (e.g., abortion) but who agree on issue Y (e.g., Latin American interventionism), and present the differences and similarities visually (they used wordclouds). Our results suggest that organic visualisation may revert the negative effects of providing potentially sensitive content. (via MIT Technology Review)
