Author Kathy Sierra says the question isn’t what do you have to know to be a Web developer; it’s how quickly can you learn and build skills. “Expertise,” says Sierra, “requires cognitive resource management.” The reason why some people just can’t make progress, she says, “is there are just too many things draining their cognitive resources.” See more signals from the O'Reilly Fluent Conference...
Designing and coding APIs in Node.js.
Getting an API design right demands far more than just figuring out which calls should do what. Public APIs — APIs meant to be used by people other than their creators — present a special set of challenges that can inform all API design. Even private APIs often find themselves with unexpected users, and can last far longer than was planned. Apigee faced the special challenge of creating a marquee API, an API for managing its APIs.
What comes first? The API or the code? Who is the API really for, and how important is the long-term maintenance of the API? Where does documentation fit? Answer these questions, and you can find the right approach.

What you need to know to make an informed choice.
Abbott and Costello’s signature wordplay sketch “Who’s on First?” is one of the most renowned comedic routines of all time. Trying to describe the routine here will do it little justice, you’ll just have to watch it yourself. As funny as it may be, the sketch reveals a crucial fact: names are important. Good names should be self-explanatory, precise and reveal intent. Bad names leave people confused and aggravated and should be avoided at all cost. When we write code, we must always think about variable names, function names, file names, etc. But naming things is hard. Phil Karlton probably said it best: “There are only two hard things in Computer Science: cache invalidation and naming things.”

CSS’ declarative model can be uniquely efficient, but requires an understanding not only of the features you want to use but the approach you want to take in decorating a document tree. That means understanding the document tree (and there may be many variations as you apply the same style sheet to multiple documents), the selectors used to identify points on the tree, the cascade that resolves conflicts among selectors, and the properties applied to that tree. Of course, the properties interact with each other and a shared model, so you’ll need to understand how the properties how to make those interactions produce your vision.
:focus'ing on users.

Web developers and web standards authors alike strive to live up to the promise of “universality” — the idea that the web should be available to all. This concept drives many innovations in web technology, as well as being fundamentally built in to the philosophy of the open standards on which the web is based.
In order to achieve this, we frequently find that having some carefully chosen information about how the user intends to view the content (a concept we’ll refer to in this article as “user context”) allows web developers to create more flexible and useful user experiences. In this post, we’ll lay out a case that it’s time to expand our view of user context to include the concept of modality (how the user is interacting with the page), but before we flesh that out, let’s take a look at “user context”.
Access not just to content, but technology.
“They learn a bit of Web stuff, and the next thing you know they think they understand programming.” I’ve heard variations of that lament for the past two decades. I’ve heard it less lately, because so many recent computing professionals built their technical careers from that bit of Web stuff.
The Web succeeded in large part because it was the easiest way for people to create electronic content and share it. Indexes and search engines made it easier to find that content. While administering files on a server and learning HTML weren’t trivial, they were much more approachable tasks than creating and distributing traditional (now largely considered desktop or native) applications.
For the most part, they still are easier.
