Why The Hell Would I Use Node.js? A Case-by-Case Tutorial

by Tomislav Capan

Node.js shines in real-time web applications employing push technology over websockets. What is so revolutionary about that? Well, after over 20 years of stateless-web based on the stateless request-response paradigm, we finally have web applications with real-time, two-way connections, where both the client and server can initiate communication, allowing them to exchange data freely. This is in stark contrast to the typical web response paradigm, where the client always initiates communication. Additionally, it’s all based on the open web stack (HTML, CSS and JS) running over the standard port 80.

Build Dumb, Refactor Smart: How to Massage Problems Out of Ruby on Rails Code

by Daniel Lewis

Sometimes, clients give us feature requests that we really don't like. It's not that we don't like our clients, we love our clients. It's not that we don't like the feature, most client-requested features are aligned perfectly with their business goals and income. Sometimes, the reason we don't like a feature request is that the easiest way to solve it is to write bad code, and we don't have an Elegant Solution on the top of our heads. This will throw many of us on fruitless searches through RubyToolbox, github, developer blogs, and stackoverflow looking for a gem or plugin or example code that will make us feel better about ourselves. Well, I'm here to tell you, it's okay to write bad code. Sometimes, bad code is easier to refactor into beautiful code than a poorly thought out solution implemented under a time-crunch.

Control Your Laptop with an Android Phone using Python, Twisted, and Django

by Martin Chikilian

It’s always fun to put your programming skills on display. A while back, I figured it’d be cool to try and control my laptop via my Android mobile device. Think about it: being able to play and pause music, start and stop programming jobs or downloads, etc., all by sending messages from your phone. Neat, huh?

Init.js: A Guide to the Why and How of Full-Stack JavaScript

by Alejandro Hernandez

After much thought, I decided to engineer a solution to the idea abandonment problem. I call it the ‘Init' project (or Init.js). The core of the idea is to have a single project to start them all, to let the developer or the technical founder make all of the essential decisions at once, and receive an appropriate starting template based on those decisions.

How a Single Front-End Engineer Can Replace a Team of Two

by Tom Kozacinski

Demand within the web design scene today has changed over the past few years: designers with front-end skills, and front-end developers with design skills, are more and more in demand. Yes, you could argue that the jobs are completely different—and maybe you straight-up don't like one of them—but truth be told, in my six years as a freelance web developer and twelve years as a designer, I’ve learned that it's much harder to get by as just a web designer or just a front-end developer. Wearing both hats has a lot of advantages: from a professional perspective alone, you can find work more easily and charge a higher rate because you’re bringing more to the table.

Growing Growth: Perform Your Own Cohort Analysis with This Open Source Code

by Alejandro Rigatuso

But this isn’t just another article about cohort analysis. If you already know the importance of the topic and want to skip the introduction, you can jump to the simulator, where you can either simulate startup growth based on retention, churn, and a number of other factors, or analyze your own PayPal logs with the code I’ve open sourced. If, however, you don’t realize that these are some of the most important metrics around–continue reading.

CloudI: Bringing Erlang's Fault-Tolerance to Polyglot Development

by Michael Truog

Clouds must be efficient to provide useful fault-tolerance and scalability, but they also must be easy to use. CloudI (pronounced "cloud-e" /klaʊdi/) is an open source cloud computing platform that is most closely related to the Platform as a Service (PaaS) clouds. CloudI differs in a few key ways, most importantly: software developers are not forced to use specific frameworks, slow hardware virtualization, or a particular operating system. By allowing cloud deployment to occur without virtualization, CloudI leaves development process and runtime performance unimpeded, while quality of service can be controlled with clear accountability.
