You know, we use ad-blockers as well.
We gotta keep those servers running though. Did you know that we publish
useful books and run
friendly conferences — crafted for pros like yourself?
E.g. our upcoming SmashingConf New York, dedicated to smart front-end
techniques and design patterns.

In case you're wondering what OAuth2 is, it's the protocol that enables anyone to log in with their Facebook account. It powers the “Log in with Facebook” button in apps and on websites everywhere.
This article shows you how “Log in with Facebook” works and explains the protocol behind it all. You’ll learn why you’d want to log in with Facebook, Google, Microsoft or one of the many other companies that support OAuth2.
Let’s get a few things out of the way first. This isn’t your regular Smashing Magazine article. It’s not a “how to“; it won’t show you how to build a better menu or improve your project tomorrow. This article shows you how a core problem in computer science works and why we're all pretending we know something for certain when we really have no idea.
You’re looking at Smashing Magazine right now because you’re standing on the shoulders of a giant assumption called "P versus NP". It’s a math problem that protects governments, runs the Internet and makes online shopping possible.
Static analyzers look at code and find problems before you run it. They do simple checks, like enforcing syntax (for example, tabs instead of spaces), and more holistic checks, like making sure your functions aren’t too complex. Static analyzers also find errors that you can’t find with testing, like instances of == when you meant ===.
Static typing is great because it keeps you out of trouble. Dynamic typing is great because it gets out of your way and lets you get your work done faster. The debate between strongly and dynamically typed languages rages on, but understanding the issue starts with weak typing and languages such as C.
C treats everything like a number. A character like a or 7 or % is the number of the ASCII symbol representing it; “true” and “false” are just 1 and 0. C defines variables with types such as int for integer and char for character, but that just defines how much memory to use. To access the variable and print it out, I need to know the type.
Animation makes games real. Movement adds excitement to a game and makes the characters more realistic. In this article, we’ll look at the Cocos2D library and how it supports programmatic animations in iPhone games.
This article is part of a series that teaches you how to create iPhone games based on the open-source game Seven Bridges. Make sure to check out the first article in the series, “Designing an Open-Source iPhone Game” and look at the source code in the Seven Bridges GitHub repository.
I love games and I’m a huge math nerd, so I made a new iPhone game based on a famous math problem called The Seven Bridges of Königsberg. I’m selling it in the App Store, but I also want to share it with everyone, so I made it open source.
This article is the first in a series that will walk through iOS programming using this game as an example. This first article gives you an overview of the game and of iOS programming in general. We’ll look at a few specific pieces and see how the whole project fits together.
You've presented the new website and everyone loves it. The design is crisp, the code is bug-free, and you're ready to release. Then someone asks, “Does it work in Japanese?”
You break out in a cold sweat: you have no idea. The website works in English, and you figured other languages would come later. Now you have to rework the whole app to support other languages. Your release date slips, and you spend the next two months fixing bugs, only to find that you’ve missed half of them.
Your website works. Now let’s make it work faster. Website performance is about two things: how fast the page loads, and how fast the code on it runs. Plenty of services will make your website load faster, from minimizers to CDNs, but making it run faster is up to you.
Little changes in your code can have gigantic performance impacts. A few lines here or there could mean the difference between a blazingly fast website and the dreaded “Unresponsive Script” dialog. This article shows you a few ways to find those lines of code with Chrome Developer Tools.
