Tales From the (en)Crypt(ion). Protoype The Back End, And Do It Your Way With Sinatra.

Rapid Prototyping with Sinatra

by Al Shaw · 11 Comments

If you’re a web designer or developer, you're well acquainted with prototyping. From raw wireframing to creating interfaces in Photoshop, designers map out how sites will work before they create them. Over the past few years, the protoyping process has changed significantly. With browser makers generally agreeing on web standards and the rise of tools such as Firebug and WebKit’s web inspector, we can sometimes skip Photoshop and go straight to the browser. Plus, JavaScript frameworks like jQuery let us play with browser events with only a few lines of code. But what if we need to do even more? As websites increasingly become web apps, we now need to prototype backend functionality, too. Learn how Sinatra, a so-called “micro” web framework, helps you create real (albeit simple) web apps extremely fast, letting you prototype flows and behavior you may want to integrate into a final product.

Web Cryptography: Salted Hash and Other Tasty Dishes

by Lyle Mullican · 30 Comments

One of the most powerful security tools available to web developers is cryptography, essentially a process by which meaningful information is turned into random noise, unreadable except where specifically intended. A web developer working on an underpowered netbook in his basement now has access to cryptosystems that major governments could only have dreamed of a few decades ago. And ignorance of cryptography is not bliss. You may think your web app’s profile is too low to worry about hackers, but attacks are frequently automated, not targeted, and a compromise of the weakest system can often give access to better-protected systems when people re-use passwords across multiple sites. Learn the three broad categories of cryptosystems that commonly relate to web applications and begin strategizing how to make your site secure.

How Big is Big Enough to Pick On?

Businesses aren't all faceless juggernauts. Some are just one or two people. Yet when we interact with them through reviews or social media, we fall into the notion that there's no real individual in the other side whose feelings can be hurt. Laura Kalbag asks us to be sure to criticize the work and not the person.

Thoughtful Modularity

What can we learn from the Mars rover about building the web? Anthony Colangelo describes NASA's new modular approach to mission planning, and suggests a similar strategy for our work on the web. The details of our work may change, but building with thoughtful modularity can help us reap the benefits of the future.

Pinpointing Expectations

In my work as a front-end developer, I’ve come to realize that expectations, and how you handle them, are one of the most integral parts of a project. Expectations are tricky things, especially because we don’t talk about them very much.
