“We went out with the original Material Design with what was a very fresh and very opinionated style. We wanted to get attention,” says Matias Duarte, the head of the Material Design group at Google. “And it was so strong and so opinionated and so successful, a lot of both the designer and developer community took it as a ‘gospel,’ perhaps is the right word.”

”We spent two years telling people ‘this is how to make Material yours,’” Duarte says, “and it didn’t work.” But he doesn’t blame developers. The problem is that Google didn’t provide the right tools. Specifically, he believes Google’s guidelines didn’t separate out the styling of the button from its function. Google wants apps to work like other Material Design apps, but it never meant for all Android apps to look like each other.

A huge amount of what a developer is doing is in their head. As we write code we need to keep a mental model of how parts of the application that have already been written and are yet to be written interact with the part that we are writing at that moment. We need to have a solid picture of exactly how the code is working as a whole and maintain that picture. It’s not easy, it requires a lot of concentration and has to remain in place while we think of creative and efficient ways to solve the problem at hand.

Developers can appear very unproductive at times, sitting staring at the screen with our headphones on and very little in the way of keyboard clackety-tap. This however is when we are doing our thinking, when we are building up, adding to and rearranging the mental model of how our code will work. This is the biggest and hardest part of development.

Imagine how it feels to have that interrupted at random by a telephone call or somebody walking over to talk to you.

May 17th is Global Accessibility Awareness Day. See the source link for more. The participate page is a great list of things to test for and be aware of.

The target audience of GAAD is the design, development, usability, and related communities who build, shape, fund and influence technology and its use. While people may be interested in the topic of making technology accessible and usable by persons with disabilities, the reality is that they often do not know how or where to start. Awareness comes first.

This article makes the important point that CSS custom properties - a.k.a. variables - are not a complete and ideal replacement for variables in preprocessors like Sass: they have different but overlapping use-cases, and custom properties are far better if used when cascading or changing the values in the browser are needed, while preprocessor variables are more performant for the browser when they perform the same role as custom properties, i.e. not repeating oneself. There’s also the issue of browser support for custom properties, but that’s another story.
