For as popular as this JavaScript run-time has become, you might be surprised to find out that it actually still isn't very easy to install Node.js on Ubuntu and other Linux distributions. It's still more of a manual process than it should be. I find myself Googling this just...

Writing about Passport.js the other day got me thinking about how authentication actually works, and more importantly how many ways it can go wrong. The naive solution is to just store a user's username/email and password directly in the database, and then check the submitted password against the...
Pretty much every user-based app and website needs to send an email to the user at some point, so eventually you'll have to deal with the joyous world of programmatic emailing. There are quite a few services popping up to help you with this, but with every app having its...
For many of us, we started out programming on desktops and servers, which seemed to have infinite memory and processing power (well, depending on when you started programming, I guess). There was little reason to optimize your code since you weren't likely to exceed the system's limits anyway. And then,...
As you probably know (or have heard), Arduino is a great platform to learn and hack on electronics that would otherwise be very difficult to use for a beginner. It's a great introduction into programming, electronics, and engineering in general. But even then, as much of an improvement as Arduino...
Node.js is great for a lot of reasons, one of which is the speed in which you can build meaningful applications. However, as we all know, this comes at the price of performance (as compared to native code). To get around this, you can write your code to interface...
Express is by far the most popular web framework for Node.js thanks to its simple API, available plugins, and huge community. Thanks to the community, there is no shortage of documentation and examples on how to use the core Express API, which is great, but it's not always immediately...
I'll admit that I was one of those people that decided to learn Node.js simply because of the buzz around it and how much everyone was talking about it. I figured there must be something special about it if it has this much support so early on in its...
First we explained how it worked, and now, thanks to Jared Stafford (and stbnps on GitHub for explanations) we can show you how to exploit it. Heartbleed is a simple bug, and therefore a simple bug to exploit. As you'll see below, it only takes about a single page of...
