A Front-End Developer’s Ode To Specifications

In the physical world, no one builds anything without detailed blueprints, because people’s lives are on the line. In the digital world, the stakes just aren’t as high. It’s called “software” for a reason: because when it hits you in the face, it doesn’t hurt as much. No one is going to die if your website goes live with the header’s left margin 4 pixels out of alignment with the image below it.

A Front-End Developer's Ode To Specifications

But, while the users’ lives might not be on the line, design blueprints (also called design specifications, or specs) could mean the difference between a correctly implemented design that improves the user experience and satisfies customers and a confusing and inconsistent design that corrupts the user experience and displeases customers.

Mobile Design Pattern: Inventory-Based Discrete Slider

Sliders are cool. When they’re done well, customers love to interact with them. When they're not done well, they can cause a lot of frustration (not to mention lost sales) by standing between your customers and what they want. And getting them wrong is surprisingly easy.

Mobile Design Pattern: Inventory-Based Discrete Slider

In this article, we will present a solution, including the design and code, for a new type of Android slider to address common problems, along with a downloadable Android mini-app for you to try out. It’s a deep dive into sliders based on a chapter in Android Design Patterns. The experimental inventory-based slider we will look at would be at home in any application that asks for a price, a size, or any other faceted input within a widely distributed range.

An Introduction To Unit Testing In AngularJS Applications

AngularJS has grown to become one of the most popular single-page application frameworks. Developed by a dedicated team at Google, the outcome is substantial and widely used in both community and industry projects.

An Introduction To Unit Testing In AngularJS Applications

One of the reasons for AngularJS’ success is its outstanding ability to be tested. It’s strongly supported by Karma (the spectacular test runner written by Vojta Jína) and its multiple plugins. Karma, combined with its fellows Mocha, Chai and Sinon, offers a complete toolset to produce quality code that is easy to maintain, bug-free and well documented.

The Skeptic’s Guide To Low-Fidelity Prototyping

Designer Paul Rand once said, “An understanding of man's intrinsic needs, and of the necessity to search for a climate in which those needs could be realized, is fundamental to the education of the designer.” Prototyping helps us to unveil and explore these human needs, opening the door to insightful interaction and more empathetic design solutions.

The Skeptic’s Guide To Low-Fidelity Prototyping

Low-fidelity prototypes, in particular, are rough representations of concepts that help us to validate those concepts early on in the design process. Throughout this article, we will look at some of the features that make low-fidelity prototyping a unique tool to radically improve your work and to build an environment in which users’ needs can be truly realized.

Icons Of Digital Design

Apple launched the Macintosh personal computer in 1984. It was more user-friendly than other PCs at that time — and, with its desktop publishing software, graphical user interface and mouse (all novel at the time), the Mac was uniquely geared to designers. Compared to what we can create on the computer today, the original Macintosh, with only 128 KB of memory, had limited capabilities. At the time, though, it opened up so many new possibilities.

Icons Of Digital Design

Of course, using a computer didn’t automatically make designers better at their craft. Instead, the new technology gave them more control and sped up their exploration process. As with anything unfamiliar, the Mac sparked debate among designers during this time: While some saw the computer as simply another tool for creating work, like a drawing pen, others saw its potential as a medium in itself.

What Every App Developer Should Know About Android

In today’s fast-paced mobile market, consumers have no patience for mobile apps that compromise their experience. “Crashes” and “Not working” are the most common feedback on Google Play for unstable or sluggish apps (including games). Those comments and ratings make hundreds of millions of potential downloaders skip those lousy apps. Sounds harsh, but that’s the way it is.

What Every App Developer Should Know About Android

An app succeeds not by chance. It is the result of the right decisions made at the right time. The most successful mobile app developers understand the importance of performance, quality and robustness across the array of mobile devices that their customers use.

“There Are More Bugs In Mobile Than… Particles In The Universe!”

Mobile is a difficult, unpredictable beast. If you run into technical problems in mobile, then you’ll know how annoying fixing them can be. That’s why we’ve teamed up with Peter-Paul Koch to create The Mobile Web Handbook, our practical new guide to dealing with front-end challenges in mobile. The book is finally ready and is now shipping worldwide. It’s available in print and as an eBook.

There Are More Bugs In Mobile Than... Particles In The Universe!

We have all been there. Whether you are developing a responsive website or an app or just dealing with WebViews, you always end up running into annoying technical problems that all of those quirky (and not so quirky) mobile browsers throw up so very often. Weird browser bugs, inconsistent CSS and JavaScript support, performance issues, mobile fragmentation and complicated nuances such as device pixels, viewports, zooming, touch event cascade, pointer and click events and the 300-millisecond delay. No, mobile isn’t actually dark matter, but it does require you to learn a few new things, some of which are quite confusing.
