Competing by mimicking - Andy Bell

In my mind, the only way to “compete” with native apps is to do better than native apps—and with the web platform consistently improving and enabling us to produce app-like experiences, with Service Workers, ES6+ JavaScript, modern CSS and Web Components: we are very much on the path to do better than native apps.

Performance Budgets That Stick - TimKadlec.com

I like Tim’s definition here:

A performance budget is a clearly defined limit on one or more performance metrics that the team agrees not to exceed, and that is used to guide design and development.

And I agree about the four attributes required for a performance budget to succeed. It must be:

  1. Concrete
  2. Meaningful
  3. Integrated
  4. Enforceable

The point is not to let the performance budget try to stand on its own, somewhere hidden in company documentation collecting dust. You need to be proactive about making the budget become a part of your everyday work.

Systems Thinking, Unlocked – Airbnb Design

Some useful lessons here for strengthening a culture of sustained work on a design system.

Creating and maintaining a design system is like planting a tree—it has to be nurtured and cared for to reap the benefits. The seed of our design system has been planted, and now our teams are working together to maintain and grow it. Our new way of working supports gives people recognition, facilitates trust, and creates strong partnerships.

Design sprint?

Our hack week at CERN to reproduce the WorldWideWeb browser was five days long. That’s also the length of a design sprint. So …was what we did a design sprint?

I’m going to say no.

On the surface, our project has all the hallmarks of a design sprint. A group of people who don’t normally work together were thrown into an instense week of problem-solving and building, culminating in a tangible testable output. But when you look closer, the journey itself was quite different. A design sprint is typical broken into five phases, each one mapped on to a day of work:

  1. Understand and Map
  2. Demos and Sketch
  3. Decide and Storyboard
  4. Prototype
  5. Test

Gathered at CERN, hunched over laptops.

There was certainly plenty of understanding, sketching, and prototyping involved in our hack week at CERN, but we knew going in what the output would be at the end of the week. That’s not the case with most design sprints: figuring out what you’re going to make is half the work. In our case, we knew what needed to be produced; we just had to figure out how. Our process looked more like this:

  1. Understand and Map
  2. Research and Sketch
  3. Build
  4. Build
  5. Build

Now you could say that it’s a kind of design sprint, but I think there’s value in reserving the term “design sprint” for the specific five-day process. As it is, there’s enough confusion between the term “sprint” in its agile sense and “design sprint”.

Blockchain and Trust - Schneier on Security

Honestly, cryptocurrencies are useless. They’re only used by speculators looking for quick riches, people who don’t like government-backed currencies, and criminals who want a black-market way to exchange money.

Bruce Schneier on the blockchain:

What blockchain does is shift some of the trust in people and institutions to trust in technology. You need to trust the cryptography, the protocols, the software, the computers and the network. And you need to trust them absolutely, because they’re often single points of failure.

Timelines of the web

Recreating the original WorldWideWeb browser was an exercise in digital archeology. With a working NeXT machine in the room, Kimberly was able to examine the source code for the first every browser and discover a treasure trove within. Like this gem in HTUtils.h:

#define TCP_PORT 80 /* Allocated to http by Jon Postel/ISI 24-Jan-92 */

Sure enough, by June of 1992 port 80 was documented as being officially assigned to the World Wide Web (Gopher got port 70). Jean-François Groff—who worked on the World Wide Web project with Tim Berners-Lee—told us that this was a moment they were very pleased about. It felt like this project of theirs was going places.

Jean-François also told us that the WorldWideWeb browser/editor was kind of like an advanced prototype. The idea was to get something up and running as quickly as possible. Well, the NeXT operating system had a very robust Text Object, so the path of least resistance for Tim Berners-Lee was to take the existing word-processing software and build a hypertext component on top of it. Likewise, instead of creating a brand new format, he used the existing SGML format and added one new piece: linking with A tags.

So the WorldWideWeb application was kind of like a word processor and document viewer mashed up with hypertext. Ted Nelson complains to this day that the original sin of the web was that it borrowed this page-based metaphor. But Nelson’s Project Xanadu, originally proposed in 1974 wouldn’t become a working reality until 2014—a gap of forty years. Whereas Tim Berners-Lee proposed his system in March 1989 and had working code within a year. There’s something to be said for being pragmatic and working with what you’ve got.

The web was also a mashup of ideas. Hypertext existed long before the web—Ted Nelson coined the term in 1963. There were conferences and academic discussions devoted to hypertext and hypermedia. But almost all the existing hypertext systems—including Tim Berners-Lee’s own ENQUIRE system from the early 80s—were confined to a local machine. Meanwhile networked computers were changing everything. First there was the ARPANET, then the internet. Tim Berners-Lee’s ambitious plan was to mash up hypertext with networks.

Going into our recreation of WorldWideWeb at CERN, I knew I wanted to convey this historical context somehow.

The World Wide Web officially celebrates its 30th birthday in March of this year. It’s kind of an arbitrary date: it’s the anniversary of the publication of Information Management: A Proposal. Perhaps a more accurate date would be the day the first website—and first web server—went online. But still. Let’s roll with this date of March 12, 1989. I thought it would be interesting not only to look at what’s happened between 1989 and 2019, but also to look at what happened between 1959 and 1989.

So now I’ve got two time cones that converge in the middle: 1959 – 1989 and 1989 – 2019. For the first time period, I made categories of influences: formats, hypertext, networks, and computing. For the second time period, I catalogued notable results: browsers, servers, and the evolution of HTML.

I did a little bit of sketching and quickly realised that these converging timelines could be represented somewhat like particle collisions. Once I had that idea in my head, I knew how I would be spending my time during the hack week.

Rather than jumping straight into the collider visualisation, I took some time to make a solid foundation to build on. I wanted to be sure that the timeline itself would be understable even if it were, say, viewed in the first ever web browser.

Progressive enhancement. Marking up (and styling) an interactive timeline that looks good in a modern browser and still works in the first ever web browser.

I marked up each timeline as an ordered list of h-events:

<li class="h-event y1968">
  <a href="https://en.wikipedia.org/wiki/NLS_%28computer_system%29" class="u-url">
    <time class="dt-start" datetime="1968-12-09">1968</time>
    <abbr class="p-name" title="oN-Line System">NLS</abbr>

With the markup in place, I could concentrate on making it look halfway decent. For small screens, the layout is very basic—just a series of lists. When the screen gets wide enough, I lay those lists out horzontally one on top of the other. In this view, you can more easily see when events coincide. For example, ENQUIRE, Usenet, and Smalltalk all happen in 1980. But the real beauty comes when the screen is wide enough to display everthing at once. You can see how an explosion of activity in the early 90s. In 1994 alone, we get the release of Netscape Navigator, the creation of HTTPS, and the launch of Amazon.com.

The whole thing is powered by CSS transforms and positioning. Each year on a timeline has its own class that gets moved to the correct chronological point using calc(). I wanted to use translateX() but I couldn’t get the maths to work for that, so I had use plain ol’ left and right:

.y1968 {
  left: calc((1968 - 1959) * (100%/30) - 5em);

For events before 1989, it’s the distance of the event from 1959. For events after 1989, it’s the distance of the event from 2019:

.y2014 {
  right: calc((2019 - 2014) * (100%/30) - 5em);

(Each h-event has a width of 5em so that’s where the extra bit at the end comes from.)

I had to do some tweaking for legibility: bunches of events happening around the same time period needed to be separated out so that they didn’t overlap too much.

As a finishing touch, I added a few little transitions when the page loaded so that the timeline fans out from its centre point.

Et voilà!

Progressive enhancement. Marking up (and styling) an interactive timeline that looks good in a modern browser and still works in the first ever web browser.

I fiddled with the content a bit after peppering Robert Cailliau with questions over lunch. And I got some very valuable feedback from Jean-François. Some examples he provided:

1971: Unix man pages, one of the first instances of writing documents with a markup language that is interpreted live by a parser before being presented to the user.

1980: Usenet News, because it was THE everyday discussion medium by the time we created the web technology, and the Web first embraced news as a built-in information resource, then various platforms built on the web rendered it obsolete.

1982: Literary Machines, Ted Nelson’s book which was on our desk at all times

I really, really enjoyed building this “collider” timeline. It was a chance for me to smash together my excitement for web history with my enjoyment of using the raw materials of the web; HTML and CSS in this case.

The timeline pales in comparison to the achievement of the rest of the team in recreating the WorldWideWeb application but I was just glad to be able to contribute a little something to the project.

Hello WorldWideWeb.

PWA2APK- Convert PWA to APK file - Appmaker.xyz

This seems to work quite nicely: convert your progressive web app into an APK file that you can then submit to the Google Play store (you’ll still have to go through all the hassle of submitting the app, but still).

I tested this with The Session and sure enough, it looks like it’s available to download from Google Play.

It’s browser updatin’ time! Firefox 65 just dropped. So did Chrome 72. Safari 12.1 is shipping with iOS 12.2.

It’s interesting to compare the release notes for each browser and see the different priorities reflected in them (this is another reason why browser diversity is A Good Thing).

A lot of the Firefox changes are updates to dev tools; they just keep getting better and better. In fact, I’m not sure “dev tools” is the right word for them. With their focus on layout, typography, and accessibility, “design tools” might be a better term.

Oh, and Firefox is shipping support for some CSS properties that really help with print style sheets, so I’m disproportionately pleased about that.

In Safari’s changes, I’m pleased to see that the datalist element is finally getting implemented. I’ve been a fan of that element for many years now. (Am I a dork for having favourite HTML elements? Or am I a dork for even having to ask that question?)

And, of course, it wouldn’t be a Safari release without a new made up meta tag. From the people who brought you such hits as viewport and apple-mobile-web-app-capable, comes …supported-color-schemes (Apple likes to make up meta tags almost as much as Google likes to make up rel values).

There’ll be a whole bunch of improvements in how progressive web apps will behave once they’ve been added to the home screen. We’ll finally get some state persistence if you navigate away from the window!

Updated the behavior of websites saved to the home screen on iOS to pause in the background instead of relaunching each time.

Maximiliano Firtman has a detailed list of the good, the bad, and the “not sure yet if good” for progressive web apps on iOS 12.2 beta. Thomas Steiner has also written up the progress of progressive web apps in iOS 12.2 beta. Both are published on Ev’s blog.

At first glance, the release notes for Chrome 72 are somewhat paltry. The big news doesn’t even seem to be listed there. Maximiliano Firtman again:

Chrome 72 for Android shipped the long-awaited Trusted Web Activity feature, which means we can now distribute PWAs in the Google Play Store!

Very interesting indeed! I’m not sure if I’m ready to face the Kafkaesque process of trying to add something to the Google Play Store just yet, but it’s great to know that I can. Combined with the improvements coming in iOS 12.2, these are exciting times for progressive web apps!

New Adventures 2019 | Part Two: Progressive Web | Abstrakt

Here’s a thorough blow-by-blow account of the workshop I ran in Nottingham last week:

Jeremy’s workshop was a fascinating insight into resilience and how to approach a web project with ubiquity and consistency in mind from both a design and development point of view.

Limiting JavaScript? - TimKadlec.com

Following on from that proposal for a browser feature that I linked to yesterday, Tim thinks through all the permutations and possibilities of user agents allowing users to throttle resources:

If a limit does get enforced (it’s important to remember this is still a big if right now), as long as it’s handled with care I can see it being an excellent thing for the web that prioritizes users, while still giving developers the ability to take control of the situation themselves.

The First Women Trained To Conquer Space - Supercluster

The cosmonaut counterparts of the Mercury women astronauts: Zhanna Yorkina, Irina Solovyova, Tatyana Kuznetsova, Valentina Ponomareva, and Valentina Tereshkova.

Ponomareva recalled there being no envy between the women in the squad. According to her, it was a healthy spirit of competition. Everyone did their best to be number one, but also supported each other’s efforts.

One of those cosmonauts went to space: none of the women training for the Mercury missions did. There would be a shockingly gap of twenty years between the launch of Valentina Tereshkova and the launch of Sally Ride.

Designing for the web ought to mean making HTML and CSS - Signal v. Noise

The towering demands inherent in certain ways of working with JavaScript are rightfully scaring some designers off from implementing their ideas at all. That’s a travesty.

Hear, hear! And before you dismiss this viewpoint as some lawn-off-getting fist-waving from “the old guard”, bear this in mind:

Basecamp is famously – or infamously, depending on who you ask – not following the industry path down the complexity rabbit hole of heavy SPAs. We build using server-side rendering, Turbolinks, and Stimulus. All tools that are approachable and realistic for designers to adopt, since the major focus is just on HTML and CSS, with a few sprinkles of JavaScript for interactivity.

It’s very heartening to hear that not everyone is choosing to JavaScript All The Things.

The calamity of complexity that the current industry direction on JavaScript is unleashing upon designers is of human choice and design. It’s possible to make different choices and arrive at different designs.

What would a world without pushbuttons look like? | Aeon Essays

A history of buttons …and the moral panic and outrage that accompanies them.

By looking at the subtexts behind complaints about buttons, whether historically or in the present moment, it becomes clear that manufacturers, designers and users alike must pay attention to why buttons persistently engender critiques. Such negativity tends to involve one of three primary themes: fears over deskilling; frustration about lack of user agency/control; or anger due to perceptions of unequal power relations.
