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! 3 seconds max, if it's not interesting then they're not interested, period! 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.

From game jam to mobile and Firefox OS I love participating in game jams, where game developers get together to craft games in a very short amount of time. I thought it would be cool to take one of my past Game Jam games, Metal vs Hipsters, and port it to the mobile web and Firefox OS. Adapting ...

NowJS and Node.js Tutorial – Creating a multi room chat client | Aditya Ravi Shankar
Node.js is a server side environment for Javascript. NowJS is a framework built on top of Node.js that connects the client side and server side Javascript effortlessly. The core of NowJS functionality lies in the now object.The now object is special because it exists on the server and the client.This means variables you set in the now object are automatically synced between client and server. Also server functions can be directly called on the client and client functions can be called directly from the server.All in realtime. You can have a working HTTP server up and running in Node.JS with just a few lines of code. This little snippet of code will create an HTTP server, listen on port 8080, and send back “Hello World” for every request. Using NowJS, communication between the client and server side is just as simple. Client Side: <script type="text/javascript"> now.ready(function(){ now.clientSideVariable = 'someValue'; now.serverSideFunction(); }); </script> Server Side: 1. 2. 3. 4. 5.
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. Studying is the first step and there’s no level of practice that can substitute for it. 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. Damn it!
Serving Static Files from Node.js
Posted: 5/6/2011 12:14 PM In the last post I showed you how to get started with Node.js on Windows. Easy, wasn’t it? Remarkably so since there was no install requirement. Note, for posterity's sake, that all of this is based on node.js as of version 0.4.7. Making Things Easier Last time we got started by unzipping the file that contained all the node files. Computer > Right-click and hit properties > Advanced System Settings (on the left) > Environment Variables > System Variables > Path > add “C:\Program Files\Node” So now the files that we use can be in a directory all their own and you still only have to type “node.exe server.js” to get started. And another tip, keep Fiddler open while you mess around with node. Serving Up A File So starting a server and returning some Html hard-coded in Javascript is awesome like we did last time, but it would be even better if we could do this by serving up Html files. First, let’s create a very basic html page. Serving Up Files And voila!
