Designing out designers?

I’m teaching myself React, the JavaScript library du jour that’s meant “for building user interfaces.” Interestingly, it doesn’t use a templating language. Instead it offers JSX: an extension of the JavaScript language that lets you write JS code that looks very much like HTML and that can be rendered into HTML. On the surface this seems like a cool idea, but the apparent simplicity starts to break down when you want to do anything other than straight-line HTML.

JavaScript prototypes

This is the first in a series of posts intended as a gentle guide through the realm of JavaScript prototypes. If you’re coming here from a class-based language like Java, PHP, C#, or C++ I suggest you put aside everything you know about how objects and inheritance work in those languages. Try to treat the way JavaScript works as its OwnThing.

JavaScript and ‘this’

Keeping your head square about JavaScript’s this variable can be a little challenging. A wonderfully concise summary on the issue is found in chuckj’s answer to a StackOverflow question (modified here to account for differences between ECMAScript 5’s strict and non-strict modes):

this can be thought of as an additional parameter to the function that is bound at the call site. If the function is not called as a method then the global object (non-strict mode) or undefined (strict mode) is passed as this.”

Let’s see what this means (pun intended?) for various scenarios.

Designers are developers

It’s common in the web and app development industry for stakeholders to make a distinction between “designers” and “developers”. One of the things I’ve noted about this distinction is that it opens the door to antagonistic perceptions and even behaviors between the two camps. At a conference a few years ago, in the presence of developers expressing disparaging views regarding designers, I suggested that, “Designers are developers.” The deafening silence suggested I had to explain what I meant:

What is a single-ended amplifier?

Single-ended amplifiers, whether made with triodes (as in the single-ended triode, or SET, amplifier), pentodes, or solid state devices, entered the high-end consumer audio consciousness a couple decades ago, and they continue to have a particular pull for a certain camp of audiophiles. This may lead some of us to wonder whether these folks are onto something that we should pay attention to.

However, there seems to be some confusion regarding what exactly single-ended amplifier are. So I thought I’d try to clear things up a little.

Displays for classic Arduinos

Arduino driving TFT display

You often hear that to work with graphic displays on the Arduino platform you need to use a Mega or other high-performance board. I got curious about how much you can actually get done on an a measly Uno and similar boards based on the classic ATmega328P. You can find the ongoing results on my wiki.

The story so far: 128×64 and smaller monochrome displays are usable. The smallest TFT displays much less so.

Open source for equitable futures

With the mainstream shift away from desktop to mobile devices, it seems the relevance of open source ecosystems is diminishing. The two major mobile OSes have a very effective grip on the mobile OS space, and they have engendered app models that do little to encourage or motivate open source designers and developers. So now might be a good time to remind ourselves of some of the benefits that open source confers. Continue reading “Open source for equitable futures”

AVA preamp chassis

AVA “SLR” remote controlled preamplifier chassis

A recent chassis redesign project I undertook for Audio by Van Alstine is now in production.

This project pushed “constraints as creative resource” to the limit. The client specified that the design language and elements from the product’s predecessor be maintained—down to the knobs, faceplate treatments, and typography.

The project brief revolved around electronic and industrial design work to bring the client’s preamplifer platform up to functional parity with current market offerings within a framework that fits with the client’s existing manufacturing capabilities. The result is a platform that is significantly more capable than what it replaces yet easier for the client to manufacture. It is also amenable to comprehensive appearance changes if and when the client deems the timing is right.

So while it might not seem there’s much innovation on the outside, there is a lot of innovation for the client on the inside.
