Material Design Text Fields Are Badly Designed — Smashing Magazine

Where to put the label in a web form? In the early days, we talked about left-aligned labels versus top-aligned labels. These days we talk about floating labels.

In this article, we explore stacking contexts, and see how they can thwart our efforts to use z-index. We'll also learn how to use this mechanism to our advantage.

Engineering dependability and fault tolerance in a distributed system - High Scalability -

This is a guest post by Paddy Byers, Co-founder and CTO at Ably, a realtime data delivery platform. You can view the original article on Ably's blog. Users need to know that they can depend on the service that is provided to them.
