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.
This extended category features articles on client-side and server-side programming languages, tools, frameworks and libraries, as well as back-end issues. Experts and professionals reveal their coding tips, tricks and ideas. Curated by Dudley Storey and Rey Bango. Subscribe to the RSS-Feed.
Once someone starts using your app, they need to know where to go and how to get there at any point. Good navigation is a vehicle that takes users where they want to go. But establishing good navigation is a challenge on mobile due to the limitations of the small screen and the need to prioritize content over chrome.
Different navigation patterns have been devised to solve this challenge in different ways, but they all suffer from a variety of usability problems. In this article, we’ll examine five basic navigation patterns for mobile apps and describe the strengths and weaknesses of each of them. If you’d like to add some patterns and spice up your designs, you can download and test Adobe XD for free and get started right away.
Voice-based interfaces are becoming commonplace. Voice assistants such as Siri and Cortana have been around for a few years, but this past holiday season, voice-driven devices from Amazon and Google made their way into millions of homes.
Recent analysis from VoiceLabs estimates that 24.5 million voice-driven devices will be shipped this year, almost four times as many as last year. As experience designers, we now have the opportunity to design voice experiences and interfaces!
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.
As a designer, you will be facing more demands and opportunities to work with digital systems that embody machine learning. To have your say about how best to use it, you need a good understanding about its applications and related design patterns.
This article illustrates the power of machine learning through the applications of detection, prediction and generation. It gives six reasons why machine learning makes products and services better and introduces four design patterns relevant to such applications. To help you get started, I have included two non-technical questions that will help with assessing whether your task is ready to be learned by a machine.
Today, CSS preprocessors are a standard for web development. One of the main advantages of preprocessors is that they enable you to use variables. This helps you to avoid copying and pasting code, and it simplifies development and refactoring.
We use preprocessors to store colors, font preferences, layout details — mostly everything we use in CSS. But preprocessor variables have some limitations.
In the first article of this series, we walked through how to put together the hardware board and all of its additional components into a single rig. I also gave you a glimpse of the decision-making process behind the selection of the board.
In this second (and last) article of the series, we will go over the code that will drive the sensor and the communication to the cloud. Additionally, we will configure a custom dashboard on Adafruit IO, so that we can visualize our data in real time.
For the past few months, I’ve been building a software-as-a-service (SaaS) application, and throughout the development process I’ve realized what a powerful tool Slack (or team chat in general) can be to monitor user and application behavior.
After a bit of integration, it’s provided a real-time view into our application that previously didn’t exist, and it’s been so invaluable that I couldn’t help but write up this show-and-tell.
The world is constantly evolving with frameworks, such as the Internet of Things (IoT) and virtual reality (VR). These and many others are opening opportunities to rethink how we approach prototyping: They introduce avenues to marry the digital software with the tangible aspect of the overall user engagement.
This two-article series will introduce readers of different backgrounds to prototyping IoT experiences with minimum code knowledge, starting with affordable proof of concept platforms, before moving to costly commercial offerings.
The landscape for the performance-minded developer has changed significantly in the last year or so, with the emergence of HTTP/2 being perhaps the most significant of all. No longer is HTTP/2 a feature we pine for. It has arrived, and with it comes server push!
Aside from solving common HTTP/1 performance problems (e.g., head of line blocking and uncompressed headers), HTTP/2 also gives us server push! Server push allows you to send site assets to the user before they've even asked for them. It’s an elegant way to achieve the performance benefits of HTTP/1 optimization practices such as inlining, but without the drawbacks that come with that practice.
I'll explain how you can install this extension that supports the web extension model (i.e. Edge, Chrome, Firefox, Opera, Brave and Vivaldi), and provide some simple tips on how to get a unique code base for all of them, but also how to debug in each browser.
Web applications, be they thin websites or thick single-page apps, are notorious targets for cyber-attacks. In 2016, approximately 40% of data breaches originated from attacks on web apps — the leading attack pattern. Indeed, these days, understanding cyber-security is not a luxury but rather a necessity for web developers, especially for developers who build consumer-facing applications.
HTTP response headers can be leveraged to tighten up the security of web apps, typically just by adding a few lines of code. In this article, we’ll show how web developers can use HTTP headers to build secure apps. While the code examples are for Node.js, setting HTTP response headers is supported across all major server-side-rendering platforms and is typically simple to set up.
Data visualization has become an important part of our everyday life, allowing us to quickly assess information. And with so many chart types out there to choose from, it should be possible to effectively solve almost any task, whether it's exploratory (i.e. researching and analyzing data to better understand it for yourself) or explanatory (i.e. reporting and communicating data to end users).
However, variety can also cause confusion, making it difficult to clearly understand the purpose of each form of data visualization. As a result, when an inappropriate type of chart is applied to data, the user not only might be confused by the information, but, more importantly, could make bad decisions based on such a presentation.
