So you’re trying to build apps huh? You’re going to need to serve them from somewhere, so do you go with Apache? Perhaps something lighter like Lighttpd or Nginx? What about picking a server-side language? Java? PHP? Or perhaps we just go with a JavaScript solution and pick Node? Let’s examine the differences in these choices…

When it comes to process-based servers, Apache is undoubtedly the most popular. In a process-based server, each simultaneous connection requires a thread, which in turn, requires some overhead. On the other hand, an asynchronous server is event-driven, and mostly handles all requests in a single thread. Asynchronous web servers include the more lightweight Lighttpd and Nginx, as well as Node’s HTTP server. They use a non-blocking I/O event loop running in a single process to serve requests.

As far as languages go, you would typically use something like Java or PHP on a synchronous server like Apache. Th

A couple of months ago, I saw a great presentation by Laurie Voss (@seldo), cofounder of NPM, on Node Microservices. Here’s a nice summary of what I got out of it:

Microservices (AKA Service Oriented Architecture) work well in the Node environment. The microservices paradigm essentially splits your ginormous monolithic app into smaller applications that run on separate machines, and interface with each other. Such a distributed system usually comes with technical and organizational advantages, as well some some improvements in resource efficiency. It does, at the same time, introduce some new problems, most of them stemming from the need for concurrency/synchronization between services.

I recently saw a presentation by Swizec Teller, a geek with a hat (@Swizec), about brining React into D3 and it was awesome! I mean, D3 and React fit together really really well. React improves a lot of things for D3: a component-like syntax, more understandable structuring, ease of modification and maintenance, and others…

For instance, you don’t need to use the complicated D3 data-setup functions, such as enter() anymore. This is because React takes over the DOM manipulation, and all you need to add are basic D3 shapes to render your data visually in a familiar React component structure. This makes things easier since React is declarative and resembles HTML. You can also take advantage of Dev Tool’s React panel on Chrome to easily see where all of your visual data components are being rendered. But let’s look at how D3 actually integrates with React. Is it really worth adding another technology to D3? We still need to use D3 for anything number
