What A/B Testing Taught Us About App Store Optimization

1.5 million apps in Apple’s App Store and another 1.5 million in Google’s Play store. That’s a lot of apps, and for a growing number of mobile users. An average user in the US will download only three new apps per month (at best), according to comScore’s “US Mobile App Report.”

What A/B Testing Taught Us About App Store Optimization

Competition in the App Store is fierce, and if an indie app developer wants to get noticed, having an amazing product is no longer enough.

Understanding Critical CSS

The web is slow, yet there are a few simple strategies to make websites faster. One of them is inlining critical CSS into the <head> of your pages, yet how exactly do you do it if your site contains hundreds of pages, or even worse, hundreds of different templates? You can't do it manually. Dean Hume explains an easy way to get it done. If you're a seasoned web developer, you might find the article obvious and self-explanatory, but it's a good piece to show to your clients and junior developers for sure. — Ed.

Understanding Critical CSS

Delivering a fast, smooth web experience is an important part of building websites today. Most of the time, we develop websites without understanding what the browser is actually doing under the hood. How exactly does the browser render our web pages from the HTML, CSS and JavaScript that we create? How can we use this knowledge to speed up the rendering of our web pages?

Efficient Image Resizing With ImageMagick

Responsive images have been keeping us on our toes for quite some time, and now that they are getting traction in browsers, they come with a scary problem: the need to efficiently resize all our image assets. The way responsive images work is that an appropriately sized image is sent to each user — small versions for users on small screens, big versions for users on big screens.

Super-Efficient Image Resizing With ImageMagick

It’s fantastic for web performance, but we have to face the grim reality that serving different sizes of images to different users means that we first need to create all of those different files, and that can be a huge pain.

A Better Way To Design For Retina In Photoshop

Recently, I had a project in which I needed to produce high-fidelity screens for a tablet. I was to present these screens on the device and also produce a clickable prototype. They needed to be pixel-perfect. The timeline was tight (as always), so I went with my go-to tool, Photoshop. I’ve been using it for over 10 years, and it gives me the fastest high-quality output.

A Better Way To Design For Retina In Photoshop

Are you designing at “Retina” resolution in Photoshop? If the answer is yes, then this article is for you. I will walk you through the problems I faced in creating Retina mockups to be displayed on a tablet device. I will then explain a way to work that is easier and gives you better performance. This is about my experience with Photoshop, but it could be applied to Illustrator and other software.

Extending In Sass Without Creating A Mess

The @extend directive in Sass is a powerful directive that facilitates the sharing of rules and relationships between selectors. However, it can produce undesirable side effects if it is not carefully implemented. Thankfully, there are many strategies for using @extend effectively that can prevent these side effects and produce clean, organized CSS.

Extending In Sass Without Creating A Mess

By examining @extend in detail and exploring these various strategies, you can accurately predict exactly what happens when you use @extend, and make more informed decisions about when to use a @mixin and when to use @extend, to ensure optimal organization and to restrict unused styles in your style sheets.

Controlling The Cache: Using Edge Side Includes In Varnish

I’m a firm believer that the best way to optimize for fast-loading mobile sites is to optimize for everyone. We don’t know when someone is on a non-mobile device but tethered to their phone, or just on awful Wi-Fi.

Controlling The Cache: Using Edge Side Includes In Varnish

In a previous article for Smashing Magazine I explained how you can speed up your websites by serving dynamic pages from a reverse proxy like Varnish. If you are new to Varnish then that article is the place to start as I'll be diving straight into configuration details here. In this article I’ll explain how you can benefit from using Varnish even when there are parts of your pages that can’t be cached for long periods, using Edge Side Includes.

A Quick Tour Of WordPress 4.0

Today, WordPress has released the first release candidate (RC) for the upcoming 4.0 version. According to the official version numbering, WordPress 4.0 is no more or less significant than 3.9 was or 4.1 will be. That being said, a new major release is always a cause for excitement! Let's take a look at the new features the team at WordPress has been working on for us.

A Quick Tour Of WordPress 4.0

Since I've always used WordPress in English, it took me a while to realize how important internationalization is. 29% of all WordPress.com installations use a non-English language which is huge and not that far from a quarter of all installations. Version 4.0 makes it much easier to get WordPress to speak your language. In fact, the first installation screen asks you to choose your native tongue. Nice!

Cache Invalidation Strategies With Varnish Cache

Phil Karlton once said, "There are only two hard things in Computer Science: cache invalidation and naming things." This article is about the harder of these two: cache invalidation. It’s directed at readers who already work with Varnish Cache. To learn more about it, you’ll find background information in “Speed Up Your Mobile Website With Varnish.”

10 microseconds (or 250 milliseconds): That’s the difference between delivering a cache hit and delivering a cache miss. How often you get the latter will depend on the efficiency of the cache — this is known as the “hit rate.” A cache miss depends on two factors: the volume of traffic and the average time to live (TTL), which is a number indicating how long the cache is allowed to keep an object. As system administrators and developers, we can’t do much about the traffic, but we can influence the TTL.
