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

10 Tools for Creating Infographics and Visualizations The author's posts are entirely his or her own (excluding the unlikely event of hypnosis) and may not always reflect the views of Moz. Hello there! I'm Miranda Rensch, Product Manager at SEOmoz and lover of visual communication. Communicating visually is one of the most effective ways to explain complex concepts and relationships, and can be a great way to explain your services/products and create valuable site content. I often use diagrams and whiteboarding in order to communicate new features and concepts internally with my team. I've compiled a list of tools you can use to create visualizations, or simply use to communicate visually with your teammates. Tools for creating simple infographics and data visualizations 1. Piktochart is a web-based tool that has six decent free themes (and a whole bunch more for the paid version) for creating simple visualizations. 2. Easel.ly is another free web-based tool for creating infographics. 3. 4. 5. [Bonus!] Tools for diagraming and wireframing
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.
