The Best Request Is No Request, Revisited

Now that HTTP/2 is enjoying greater ubiquity than ever, it’s especially important to challenge the once unquestionable rule of resource bundling in client side performance. Join Stefan Baumgartner as he walks you through the potential pitfalls and ill effects of bundling in HTTP/2 environments.

Fait Accompli: Agentive Tech Is Here

Artificial Intelligence is an extremely hot topic. The process in which everyday devices become more aware of our needs and “learn” to adapt to those needs will play a big part in the future of user experience. In this excerpt from Designing Agentive Technology, AI That Works for People Chris Noessel, examines agentive technology and how it works in behalf of the user.

Using HTTP/2 Responsibly: Adapting for Users

Depending on your audience’s capabilities, a site optimized for HTTP/2 may be detrimental for a segment of your users. Jeremy Wagner shows us how adaptive content delivery can improve site performance caused by incompatible browsers.

Considering How We Use HTTP/2

HTTP/2 is a rough experience on incompatible browsers. Jeremy Wagner explains the true extent of real-world performance problems, and how to adapt delivery of site assets to a user’s connection.

Practical SVG

“Sizing svg is more complicated than sizing an img,” writes Chris Coyier in this excerpt from his new A Book Apart title Practical SVG. But, he continues, it’s complicated in a good way—it gives us more control and opens up some interesting new possibilities. Read on.

Interaction Is an Enhancement

The web has an endless supply of single-point-of-failure horror stories, where sites serve up blank and blocked pages to dumbstruck users. But the fault is not with JavaScript and other technologies—it’s with how we use them, banking on them alone instead of diversifying how we deliver our experiences. In this excerpt from Chapter 5 of Adaptive Web Design, Second Edition, Aaron Gustafson explains why understanding and working within limitations is the key to building resilient websites.

URLs Beyond the Web

As the newest operating systems for Android and iOS enable deep-linking directly into third-party apps, Anthony Colangelo sees an expanding definition of “the web” and an opportunity to better serve our users.

Performance: Showing Versus Telling

The technical aspects of performance optimization are indisputably important. But the social work—convincing peers, managers, and clients that performance optimization merits their attention—often gets short shrift. Lara Hogan shows us how we can go beyond charts, graphs, and numbers to show performance rather than merely tell it—and effect a genuine culture shift in the process.

Instant Web

For some, Facebook’s Instant Articles is a sign that the traditional web stack is incapable of giving users a first-class reading experience. But the sluggish performance of the web isn’t due to an inherent flaw in the technology. That particular problem originates between the seat and the keyboard, where builders make choices that bloat their sites. For Mark Llobrera, Instant Articles is a sign that we need to prioritize performance like we actually mean it.
