The Data Visualization Beginner’s Toolkit #2: Visualization Tools

The Data Visualization Beginner’s Toolkit #2: Visualization Tools
(Note: if you are new to this series, the DVBTK doesn’t teach you how to do visualization. Rather it is meant to help people find a less chaotic and more effective path towards the acquisition of the necessary skills to become a data visualization pro. To know more, make sure to read the introduction to the series first.) The DVBTK #1 introduced books and study material to make sure you acquire the right knowledge in the right order. That said, it is extremely important to realize that good visualization cannot happen without practice. But if you want to do visualization you need some tools right? Here is the guidance. And there is more to come! I felt you needed to know more about each tool, so I decided to interview (at least) one data visualization professional with proven and long-lasting experience with it. Golden Rules of Visualization Tools First of all you need some fundamental rules. Rule #1: No tool will turn you into a pro. Rule #2: First learn one single tool very well. Excel

Tal Raviv — Being a Developer Makes You Valuable. Learning How to Market Makes You Dangerous Being a Developer Makes You Valuable. Learning How to Market Makes You Dangerous I love engineering, and not just because I’m a nerd. The best part of engineering isn’t the technical details or the particular science behind it, rather, it’s the opportunity to solve an unfairly hard problem in a way no one has before. In business and marketing there’s a word for that kind of person – hustler – or, in the software startup space, growth hacker. As much as engineers like to joke about our counterparts in sales and marketing, the most successful sales and marketers think like engineers. I got an email from a student who reached out via our “breaking every rule” page. He described his previous entrepreneurial experience: I started a small startup which unfortunately has refused to take off am guessing the idea wasn’t all that awesome or it will pick up after a year, whatever. I checked out Wasswa’s site. After exchanging some links for getting started, Wasswa sent me this: Becoming Dangerous

Think Twice: How the Gut's "Second Brain" Influences Mood and Well-Being As Olympians go for the gold in Vancouver, even the steeliest are likely to experience that familiar feeling of "butterflies" in the stomach. Underlying this sensation is an often-overlooked network of neurons lining our guts that is so extensive some scientists have nicknamed it our "second brain". A deeper understanding of this mass of neural tissue, filled with important neurotransmitters, is revealing that it does much more than merely handle digestion or inflict the occasional nervous pang. The little brain in our innards, in connection with the big one in our skulls, partly determines our mental state and plays key roles in certain diseases throughout the body. Although its influence is far-reaching, the second brain is not the seat of any conscious thoughts or decision-making. This multitude of neurons in the enteric nervous system enables us to "feel" the inner world of our gut and its contents. The second brain informs our state of mind in other more obscure ways, as well.

Teaching my 5 year old daughter to code… | In The Attic So I decided to try and teach my 5 year old daughter some basic logical thinking and development principals. My little girl's shown a keen interest in what I do for a job amongst other things recently. She's a great reader and writer for her age and so I started looking around for a simple scripting language or similar that I could teacher her. Now the thing to remember about kids is this, no matter how smart they are they all have the attention span of a gnat! I spent the next 45 minutes talking to her about how to make the robot move, at first she thought it was a game and that she had to click on stuff but she quickly got the hang of it. Here she is trying to figure out how many squares to make the on-screen robot move. This is the program before script execution. This is the program after execution. In total I spent a good hour going through stuff with her, helping her out and debugging the code with her to produce this.

Set up Jenkins-CI on Ubuntu for painless Rails3 app CI testing - Nepal on Rails D3.js - Data-Driven Documents Designing Better JavaScript APIs Advertisement At some point or another, you will find yourself writing JavaScript code that exceeds the couple of lines from a jQuery plugin. Your code will do a whole lot of things; it will (ideally) be used by many people who will approach your code differently. They have different needs, knowledge and expectations. This article covers the most important things that you will need to consider before and while writing your own utilities and libraries. Peter Drucker once said: “The computer is a moron.” Table of Contents Fluent Interface The Fluent Interface1 is often referred to as Method Chaining (although that’s only half the truth). Aside from major simplifications, jQuery offered to even out severe browser differences. Method Chaining The general idea of Method Chaining6 is to achieve code that is as fluently readable as possible and thus quicker to understand. Note how we didn’t have to assign the element’s reference to a variable and repeat that over and over again. Going Fluent

We'll get it right next time: Gut vs Head Dan Gardner's Risk: The Science and Politics of Fear offers a psychological model for how we, as ex-hunter-gatherers, make decisions about stuff. Apparently we have two separate modes of thought, which psychologists call System One and System Two and Gardner, with rather more of an eye on bestseller status, calls Head and Gut. Instinctively, you can guess what those mean and some careful thought plus a bit of research would tell you you were right. Gut is where elections are won and lost. Head might sway politicos, journalists, academics and hobbyists/junkies; a full 1% of the population taken care of. Everyone else has better things to do with their time than read economic history or position papers, and so relies on headlines, soundbites and topical comedy shows to tell them what's going on. Gut is what's killing Labour right now. Doesn't matter. There's a point to this, but at the risk of creating an artificial sense of suspense, I'm going to leave it to my next post.
