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 Barcelona, dedicated to smart front-end techniques and design patterns.

Despite improvements in broadband and wireless Internet, load is in many ways more of an issue now than it was five years ago. The proliferation of mobile devices, increased user expectations, and the very real risks of losing customers and dropping in search result rankings have laid a heavy burden on developers to optimize loading time at all costs.
In building websites primarily for the desktop environment, the Web development community previously didn’t spend much time concerning itself with load issues. Selecting the proper image formats and saving our JPEGs for the Web was about as far as many of us would go. On the whole, our hardware and software tools are forgiving enough to accommodate sloppy code. Our production environments can handle thousands of visitors per day, and our clients tend to have predictably manageable traffic.Read more...
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
% 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.
There are several ways to make navigation responsive, and usually the solution we need is quite straightforward. But despite the apparent simplicity, there are many underlying factors which, when thought through and implemented properly, can make a simple solution even better without adding more complexity to the user interface.
One of the problems I’ve encountered while building responsive navigations is that browsers currently don’t support CSS3 transitions to a height which is defined auto. Most of the time, we shouldn’t use fixed height either because the height of menu items might not be the same in all browsers, and the number of items may change. I also always try to reduce the weight of pages I build, so I’ve been wanting a solution that doesn’t require a big library such as jQuery to work.Read more...
Since the introduction of the iPhone in 2007, touchscreen mobile devices have exploded in popularity. They have introduced new problems, new solutions, new interactions, new ways of thinking and, of course, new costs to our clients.
The most important question on everyone’s mind — clients and developers alike — is, “How can we provide a great Web experience to our users on mobile?”Read more...
Responsive Web design has been evolving rapidly ever since Ethan Marcotte coined the term two years ago. Since then, techniques have emerged, become best practices and formed part of our ever-changing methodology.
A few obvious examples are the multitude of responsive image techniques, conditional loading, and responsive design and server-side components (RESS), among many other existing and emerging strands stemming from the core concept of responsive Web design.Read more...
Earlier this year, I was in the beginning stages of a redesign for our company’s website. We had already been planning to use a straightforward responsive approach to Web design, which is our preferred solution for multi-device support.
After hearing some frank discussions at An Event Apart conference in Boston about the limitations and challenges of responsive Web design, I realized that our solution needed a bit of adjustment.Read more...
Whether it’s V8, SpiderMonkey (Firefox), Carakan (Opera), Chakra (IE) or something else, doing so can help you better optimize your applications. That's not to say one should optimize for a single browser or engine. Never do that. There are many common pitfalls when it comes to writing memory-efficient and fast code, and in this article we’re going to explore some test-proven approaches for writing code that performs better.Read more...
We all know that WordPress is awesome - but being awesome isn't always enough. Does it perform well under pressure? Can it deal with traffic from millions of visitors every month? There's no question that WordPress can be used for your or my blog, but what about multi-authored blogs with thousands of comments? How do developers make it scale and perform?
I talked to the developers behind some of the biggest WordPress blogs on the planet and asked them to tell me their secrets. Now I get to share them with you.Read more...
If you’re a developer of mobile Web apps, then you’ve heard this before: Native apps perform better than Web apps. But what does “perform better” mean? In the context above, performance is usually about measurable aspects such as loading time and responsiveness to user interaction. But more often than not, statements about performance lie within the realm of animations and transitions and how smooth they are. [Links checked February/21/2017]
We humans tend to perceive a transition as being “smooth” when the number of frames per second (FPS) drawn on the screen is above a certain cognitive threshold — about 30 or so, arguably.Read more...
The beauty of WordPress is in how easy it is to adapt for different tasks. One can extend it with just a couple of lines of code. In this post, we’ll review 10 shortcode snippets that will tweak and optimize your WordPress theme. You can add all of these code snippets to the
functions.php file in your WordPress theme.
One thing that can go wrong in WordPress magazine themes is when users include too many words before the
more tag. Sure, they could handcraft the excerpt in the dedicated field, but on a website that has hundreds of posts and on which the text above the
more tag has always been used as the excerpt, going back to create excerpts for all of those posts by hand would be cumbersome. In this case, we can limit the number of words shown in the excerpt by using the code displayed below.
Images have always been the heaviest component of websites. Even if high-speed Internet access gets cheaper and more widely available, websites will get heavier more quickly. If you really care about your visitors, then spend some time deciding between good-quality images that are bigger in size and poorer-quality images that download more quickly. And keep in mind that modern Web browsers have enough power to enhance images right on the user’s computer. In this article, I’ll demonstrate one possible solution.
Let’s refer to an image that I came across recently in my job. As you can see, this image is of stage curtains and has some (intentional) light noise:
Optimizing an image like this would be a real pain because it contains a lot of red (which causes more artifacts in JPEG) and noise (which creates awful artifacts in JPEG and is bad for PNG packing). The best optimization I could get for this image was 330 KB JPEG, which is quite much for a single image. So, I decided to do some experiments with image enhancement right in the user’s browser.Read more...
In this article I'll be reviewing a few techniques that will help Web designers and UI professionals to improve their error pages in order to engage visitors and improve overall website experience. As C. S. Lewis once said, “Failures are finger posts on the road to achievement”. Web designers should take this to heart.
I’ll be focusing on error and maintenance pages, both from tracking as well as usability perspectives. I’ll also be providing a good number of examples on how to use analytics and defensive design in order to optimize user experience for such pages. First, let’s go over the error pages and cover the questions on how to optimize them efficiently.Read more...
