Node.js has memory limitations that you can hit quite easily in production. You'll know this if you ever tried to load a large data file into your Node.js application. But where exactly are the limits of memory in Node.js? In this short post we'll push Node.js to it's limits to figure out where those limits are. We'll also cover some practical techniques you can use to work around the memory limitations and get your data to fit into memory. »
I've been doing a lot of data analysis in JavaScript. It makes sense for me to work in JavaScript, because I already use it and that's where my visualizations normally end up. JavaScript has a very rich ecosystem of visualization libraries so that's not surprising. All these visualization libraries are browser based... which is great if that's where you want your visualization to be. It's not so great if you just want to render a chart to an image, say to store for later or to include in some kind of report. »

Have you ever struggled to keep a game or application working as it evolves and as the complexity ramps up? Software is composed of a suite of interacting components that are wired together in a particular way. As the number of interacting components grows the wiring and the number of connections between components grows exponentially (a phenomenon known as Metcalfe's law). »
