Reading Dawn by Octavia Butler.
The ideas and images that come to mind when you think of technology as an instrument are more useful than if you think of it as a tool. Instruments — I’m specifically talking about musical instruments — are a way to create culture.
You approach instruments with a set of expectations and associations that are more humane. It’s built into their very purpose. Instruments are meant to make something for other people, not making things. When you use an instrument, you have an expectation that it is going to take effort to use it well. Using an instrument takes practice. You form a relationship with that object. It becomes part of your identity that you make something with it. You tune it. You understand that there’s no such thing as a “best” guitar in the same way that there’s not necessarily a “best” phone.
Twitter and Instagram progressive web apps
The two major candidates are Twitter and Instagram. I added them to my home screen, and banished the native apps off to a separate screen. I’ve been using both progressive web apps for a few months now, and I have to say, they’re pretty darn great.
There are a few limitations compared to the native apps. On Twitter, if you follow a link from a tweet, it pops open in Safari, which is fine, but when you return to Twitter, it loads anew. This isn’t any fault of Twitter—this is the way that web apps have worked on iOS ever since they introduced their weird
web-app-capable meta element. I hope this behaviour will be fixed in a future update.
Also, until we get web notifications on iOS, I need to keep the Twitter native app around if I want to be notified of a direct message (the only notification I allow).
Apart from those two little issues though, Twitter Lite is on par with the native app.
Instagram is also pretty great. It too suffers from some navigation issues. If I click through to someone’s profile, and then return to the main feed, it also loads it anew, losing my place. It would be great if this could be fixed.
For some reason, the Instagram web app doesn’t allow uploading multiple photos …which is weird, because I can upload multiple photos on my own site by adding the
multiple attribute to the
input type="file" in my posting interface.
Apart from that, though, it works great. And as I never wanted notifications from Instagram anyway, the lack of web notifications doesn’t bother me at all. In fact, because the progressive web app doesn’t keep nagging me about enabling notifications, it’s a more pleasant experience overall.
Something else that was really annoying with the native app was the preponderance of advertisements. It was really getting out of hand.
Well …(looks around to make sure no one is listening)… don’t tell anyone, but the Instagram progressive web app—i.e. the website—doesn’t have any ads at all!
Here’s hoping it stays that way.
I really, really like the way that this straightforward accessibility guide is subdivided by discipline. As Maya wrote in the blog post announcing its launch:
Each person on a team, whether you’re a manager, designer, or developer, has a role to play. Your responsibilities are different depending on your role. So that’s how we structured the guide, with a separate section for each of five roles:
- Product management
- Content design
- UX design
- Visual design
- Front-end development
A good explanation of web components, complete with some code examples.
Web Components are not a single technology. Instead, they are series of browser standards defined by the W3C allowing developers to build components in a way the browser can natively understand. These standards include:
- HTML Templates and Slots – Reusable HTML markup with entry points for user-specific markup
- Shadow DOM – DOM encapsulation for markup and styles
- Custom Elements – Defining named custom HTML elements with specific behaviour
There are a lot of static site generators out there!
I remember Jason telling me about this weird service worker caching behaviour a little while back. This piece is a great bit of sleuthing in tracking down the root causes of this strange issue, followed up with a sensible solution.
This strikes me as a sensible way of thinking about machine learning: it’s like when we got relational databases—suddenly we could do more, quicker, and easier …but it doesn’t require us to treat the technology like it’s magic.
An important parallel here is that though relational databases had economy of scale effects, there were limited network or ‘winner takes all’ effects. The database being used by company A doesn’t get better if company B buys the same database software from the same vendor: Safeway’s database doesn’t get better if Caterpillar buys the same one. Much the same actually applies to machine learning: machine learning is all about data, but data is highly specific to particular applications. More handwriting data will make a handwriting recognizer better, and more gas turbine data will make a system that predicts failures in gas turbines better, but the one doesn’t help with the other. Data isn’t fungible.
Paul Ford explains version control in a way that is clear and straightforward, while also being wistful and poetic.
I had idle fantasies about what the world of technology would look like if, instead of files, we were all sharing repositories and managing our lives in git: book projects, code projects, side projects, article drafts, everything. It’s just so damned … safe. I come home, work on something, push the changes back to the master repository, and download it when I get to work. If I needed to collaborate with other people, nothing would need to change. I’d just give them access to my repositories (repos, for short). I imagined myself handing git repos to my kids. “These are yours now. Iteratively add features to them, as I taught you.”
Components and concerns
But in this age of components, many people are pointing out that it makes sense to separate things according to their function. Here’s the Diana Mounter in her excellent article about design systems at Github:
This echoes a point made previously in a slidedeck by Cristiano Rastelli.
Separating interfaces according to the purpose of each component makes total sense …but that doesn’t mean we have to stop separating structure, presentation, and behaviour! Why not do both?
In her article, Pattern Library First: An Approach For Managing CSS, Rachel advises starting every component with good markup:
Your starting point should always be well-structured markup.
This ensures that your content is accessible at a very basic level, but it also means you can take advantage of normal flow.
That’s basically an application of starting with the rule of least power.
In chapter 6 of Resilient Web Design, I outline the three-step process I use to build on the web:
- Identify core functionality.
- Make that functionality available using the simplest possible technology.
That chapter is filled with examples of applying those steps at the level of an entire site or product, but it doesn’t need to end there:
We can apply the three‐step process at the scale of individual components within a page. “What is the core functionality of this component? How can I make that functionality available using the simplest possible technology? Now how can I enhance it?”
There’s another shared benefit to separating concerns when building pages and building components. In the case of pages, asking “what is the core functionality?” will help you come up with a good URL. With components, asking “what is the core functionality?” will help you come up with a good name …something that’s at the heart of a good design system. In her brilliant Design Systems book, Alla advocates asking “what is its purpose?” in order to get a good shared language for components.
My point is this:
- Separating structure, presentation, and behaviour is a good idea.
- Separating an interface into components is a good idea.
Those two good ideas are not in conflict. Presenting them as though they were binary choices is like saying “I used to eat Italian food, but now I drink Italian wine.” They work best when they’re done in combination.
Rachel goes into detail on how she uses pattern libraries—built with Fractal to build interfaces. I know it sounds like we paid her to say all the nice things about Fractal, but honestly, we didn’t even know she was writing this article!
After discovering Fractal two years ago, we have moved every new project — large and small — into Fractal.
