Paleolithic Nostalgia

Why do we long for a time when the average life span was 22 and everyone was wracked by tuberculosis?

This was the problem I had with Yuval Noah Harari’s Sapiens (and to a lesser extent with Rutger Bregman’s Humankind):

Paleolithic peoples, so the tale goes, spent most of Tuesday strolling under Baobab trees, running their hands through the long elephant grass, and breathing in the sweet dust of the open Savannah. On Wednesdays they carefully chipped away the edges of Levallois blades, swept dust out of the home cave, and snacked on freshly gathered almonds. On Thursdays they gathered into small bands – a hand-picked selection of the finest endurance runners this side of Nairobi – tracked down an elephant, and sprinted after it barefoot for nine hours until the creature – dehydrated, exhausted, and unable to sweat out the excess heat – crumpled into a violently sad face-plant in the hot, gritty sand. Our strapping, supple ancestors jogged to a halt beside it, barely out of breath, to carve up its flesh and bring home the elephant bacon. Later that evening they would break their 36 hour intermittent fast, retire to the lake, and engage in polyamorous affairs.

The cage

I subscribe to Peter Gasston’s newsletter, The Tech Landscape. It’s good. Peter’s a smart guy with his finger on the pulse of many technologies that are beyond my ken. I recommend subscribing.

But I was very taken aback by what he wrote in issue 202. It was to do with algorithmic recommendation engines.

This week I want to take a little dump on a tweet I read. I’m not going to link to it (I’m not that person), but it basically said something like: “I’m afraid to Google something because I don’t want the algorithm to think I like it, and I’m afraid to click a link because I don’t want the algorithm to show me more like it… what a cage.”

I saw the same tweet. It resonated with me. I had responded with a link to a post I wrote a while back called Get safe. That post made two points:

  1. GET requests shouldn’t have side effects. Adding to a dossier on someone’s browsing habits definitely counts as a side effect.
  2. It is literally a fundamental principle of the web platform that it should be safe to visit a web page.

But Peter describes ubiquitous surveillance as a feature, not a bug:

It’s observing what someone likes or does, then trying to make recommendations for more things like it—whether that’s books, TV shows, clothes, advertising, or whatever. It works on probability, so it’s going to make better guesses the more it knows you; if you like ten things of type A, then liking one thing of type B shouldn’t be enough to completely change its recommendations. The problem is, we don’t like “the algorithm” if it doesn’t work, and we don’t like it if works too well (“creepy!”). But it’s not sinister, and it’s not a cage.

He would be correct if the balance of power were tipped towards the person actively looking for recommendations. As I said in my earlier post:

Don’t get me wrong: building a profile of someone based on their actions isn’t inherently wrong. If a user taps on “like” or “favourite” or “bookmark”, they are actively telling the server to perform an update (and so those actions should be POST requests). But do you see the difference in where the power lies?

When Peter says “it’s not sinister, and it’s not a cage” that may be true for him, but that is not a shared feeling, as the original tweet demonstrates. I don’t think it’s fair to dismiss someone else’s psychological pain because you don’t think they “get it”. I’m pretty sure everyone “gets” how recommendation engines are supposed to work. That’s not the issue. Trying to provide relevant content isn’t the problem. It’s the unbelievably heavy-handed methods that make it feel like a cage.

Peter uses the metaphor of a record shop:

“The algorithm” is the best way to navigate a world of infinite choice; imagine you went to a record shop (remember them?) which had every recording ever released; how would you find new music? You’d either buy music by bands you know you already liked, or you’d take a pure gamble on something—which most of the time would be a miss. So you’d ask a store worker, and they’d recommend the music they liked—but that’s no guarantee you’d like it. A good worker would ask what type of music you like, and recommend music based on that—you might not like all the recommendations, but there’s more of a chance you’d like some. That’s just what “the algorithm” does.

But that’s not true. You don’t ask “the algorithm” for a recommendation—it foists them on you whether you want them or not. A more apt metaphor would be that you walked by a record shop once and the store worker came out and followed you down the street, into your home, and watched your every move for the rest of your life.

What Peter describes sounds great—a helpful knowledgable software agent that you ask for recommendations. But that’s not what “the algorithm” is. And that’s why it feels like a cage. That’s why it is a cage.

The original tweet was an open, honest, and vulnerable insight into what online recommendation engines feel like. That’s a valuable insight that should be taken on board, not dismissed.

And what a lack of imagination to look at an existing broken system—that doesn’t even provide good recommendations while making people afraid to click on links—and shrug and say that this is the best we can do. If this really is “is the best way to navigate a world of infinite choice” then it’s no wonder that people feel like they need to go on a digital detox and get away from their devices in order to feel normal. It’s like saying that decapitation is the best way of solving headaches.

Imagine living in a surveillance state like East Germany, and saying “Well, how else is the government supposed to make informed decisions without constantly monitoring its citizens?” I think it’s more likely that you’d feel like you’re in a cage.

Apples to oranges? Kind of. But whether it’s surveillance communism or surveillance capitalism, there’s a shared methodology at work. They’re both systems that disempower people for the supposedly greater good of amassing data. Both are built on the false premise that problems can be solved by getting more and more data. If that results in collateral damage to people’s privacy and mental health, well …it’s all for the greater good, right?

It’s fucking bullshit. I don’t want to live in that cage and I don’t want anyone else to have to live in it either. I’m going to do everything I can to tear it down.

Still Hoping for Better Native Page Transitions | CSS-Tricks

It would be nice to be able to animate the transition between pages if we want to on the web without resorting to hacks or full-blown architecture choices to achieve it.

Amen, Chris, amen!

The danger here is that you might pick a single-page app just for this ability, which is what I mean by having to buy into a site architecture just to achieve this.

Remote to who? A working letter

The idea that your job should be the primary source of meaning in your life is an elaborately made trap, propped up across industries, designed to make you a loyal worker who uses the bulk of their intellectual and creative capacity to further their own career.

Reading resonances

In today’s world of algorithmic recommendation engines, it’s nice to experience some serendipity every now and then. I remember how nice it was when two books I read in sequence had a wonderful echo in their descriptions of fermentation:

There’s a lovely resonance in reading @RobinSloan’s Sourdough back to back with @EdYong209’s I Contain Multitudes. One’s fiction, one’s non-fiction, but they’re both microbepunk.

Robin agreed:

OMG I’m so glad these books presented themselves to you together—I think it’s a great pairing, too. And certainly, some of Ed’s writing about microbes was in my head as I was writing the novel!

I experienced another resonant echo when I finished reading Rebecca Solnit’s A Paradise Built in Hell and then starting reading Rutger Bregman’s Humankind. Both books share a common theme—that human beings are fundamentally decent—but the first chapter of Humankind was mentioning the exact same events that are chronicled in A Paradise Built in Hell; the Blitz, September 11th, Katrina, and more. Then he cites from that book directly. The two books were published a decade apart, and it was just happenstance that I ended up reading them in quick succession.

I recommend both books. Humankind is thoroughly enjoyable, but it has one maddeningly frustrating flaw. A Paradise Built in Hell isn’t the only work that influenced Bregman—he also cites Yuval Noah Harari’s Sapiens. Here’s what I thought of Sapiens:

Yuval Noah Harari has fixated on some ideas that make a mess of the narrative arc of Sapiens. In particular, he believes that the agricultural revolution was, as he describes it, “history’s biggest fraud.” In the absence of any recorded evidence for this, he instead provides idyllic descriptions of the hunter-gatherer lifestyle that have as much foundation in reality as the paleo diet.

Humankind echoes this fabrication. Again, the giveaway is that the footnotes dry up when the author is describing the idyllic pre-historical nomadic lifestyle. Compare it with, for instance, this description of the founding of Jericho—possibly the world’s oldest city—where researchers are at pains to point out that we can’t possibly know what life was like before written records.

I worry that Yuval Noah Harari’s imaginings are being treated as “truthy” by Rutger Bregman. It’s not a trend I like.

Still, apart from that annoying detour, Humankind is a great read. So is A Paradise Built in Hell. Try them together.

Never Been Seen | Science Museum Group Collection

This is such a great use of an API—you can choose to view an object in the museum’s collection that no one else has seen yet.

It’s like the opposite of Amazon’s recommendation engine: “No one has ever purchased these items together…”

Should The Web Expose Hardware Capabilities? — Smashing Magazine

This is a very thoughtful and measured response to Alex’s post Platform Adjacency Theory.

Unlike Alex, the author doesn’t fire off cheap shots.

Also, I’m really intrigued by the idea of certificate authorities for hardware APIs.

Conditional JavaScript - JavaScript - Dev Tips

This is a good round-up of APIs you can use to decide if and how much JavaScript to load. I might look into using storage.estimate() in service workers to figure out how much gets pre-cached.

Audio

I spent the last couple of weekends rolling out a new feature on The Session. It involves playing audio in a web page. No big deal these days, right? But the history involves some old file formats…

The first venerable format is ABC notation. File extension: .abc, mime type: text/vnd.abc. It’s an ingenious text format for musical notation using ASCII. The metadata of the piece of music is defined in JSON-like key/value pairs. Then the contents are encoded with letters: A, B, C, etc. Uppercase and lowercase denote different octaves. Numbers can be used for note lengths.

The format was created by Chris Walshaw in 1997 when dial-up was the norm. With ABC, people were able to swap tunes on email lists or bulletin boards without transferring weighty image or sound files. If you had ABC software on your computer, you could convert that lightweight text file into sheet music …or audio.

That brings me to the second old format: midi files. File extension: .mid, mime-type: audio/midi. Like ABC, it’s a lightweight format for encoding the instructions for music instead of the music itself.

Think of it like SVG: instead of storing the final pixels of an image, SVG stores the instructions for drawing the image instead. The instructions in a midi file are like “play this note for this long on this instrument.” Again, as with ABC, you need some software to turn the instructions into sound.

There was a time when lots of software could play midi files. Quicktime on the Mac, for example. You could even embed midi files in web pages. I mean literally embed them …with the embed element. No Geocities page was complete without an autoplaying midi file.

On The Session, people submit tunes in ABC format. Then, using the amazing ABCJS JavaScript library, the ABC is turned into SVG on the fly! For years I’ve also offered midi files, generated on the server from the ABC notation.

But times have changed. These days it’s hard to find software that plays midi files. Quicktime doesn’t do it anymore. And you’d need to go to the app store on iOS to find a midi file player. It’s time to phase out the midi files on The Session.

I still want to provide automatically-generated audio though. Fortunately ABCJS gives me a way to do this. But instead of using the old technology of midi files, it uses a more modern browser feature: the Web Audio API.

The end result sounds like a midi file, but the underlying technique is more like a synthesiser. There’s a separate mp3 file for each note. The JavaScript figures out how long each “sample” needs to be played for, strings them all together, and outputs them with Web Audio. So you’ve got cutting-edge browser technology recreating a much older file format. Paul Rosen—the creator of ABCJS—has a presentation explaining how it all works under the hood.

Not only is there a separate short mp3 file for each note in seven octaves, but if you want the sound of a different instrument, you need samples for all seven octaves in that instrument. They’re called soundfonts.

Paul provides soundfonts for ABCJS. It’s a repo that was forked from this repo from Benjamin Gleitzman. And here’s where it gets small worldy…

The reason why Benjamin has a repo of soundfonts is because he needed to create midi-like audio in the browser. He wanted to do this for a project on September 28th and 29th, 2013 …at Science Hack Day San Francisco!

I was there too—working on my own audio-related hack—and I remember the excellent (and winning) hack that Benjamin worked on. It was called Symphony of Satellites and it’s still online along with the promo video. Here’s Benjamin’s post-hackday write-up from seven years ago.

It’s rare that the worlds of the web and Irish music cross over. When I got to meet Paul—creator of ABCJS—at a web conference a couple of years ago it kind of blew my mind. Last weekend when I set out to dabble with a feature on The Session, I certainly didn’t expect to stumble on a connection to Science Hack Day! (Aside: the first Science Hack Day was ten years ago—yowzers!)

Anyway, I was able to get that audio playback working on The Session. Except for some weirdness on iOS that I had to fix. But that’s a hack for another day.

Web Platform Design Principles

Principles behind the design of web APIs:

  • Put user needs first (Priority of Constituencies)
  • It should be safe to visit a web page
  • Trusted user interface should be trustworthy
  • Ask users for meaningful consent when appropriate
  • Support the full range of devices and platforms (Media Independence)

I should add these to my collection.

Caching and storing

When I was speaking at conferences last year about service workers, I’d introduce the Cache API. I wanted some way of explaining the difference between caching and other kinds of storage.

The way I explained was that, while you might store stuff for a long time, you’d only cache stuff that you knew you were going to need again. So according to that definition, when you make a backup of your hard drive, that’s not caching …becuase you hope you’ll never need to use the backup.

But that explanation never sat well with me. Then more recently, I was chatting with Amber about caching. Once again, we trying to define the difference between, say, the Cache API and things like LocalStorage and IndexedDB. At some point, we realised the fundamental difference: caches are for copies.

Think about it. If you store something in LocalStorage or IndexedDB, that’s the canonical home for that data. But anything you put into a cache must be a copy of something that exists elsewhere. That’s true of the Cache API, the browser cache, and caches on the server. An item in one of those caches is never the original—it’s always a copy of something that has a canonical home elsewhere.

By that definition, backing up your hard drive definitely is caching.

Anyway, I was glad to finally have a working definition to differentiate between caching and storing.

Standards processing

I’ve been like a dog with a bone the way I’ve been pushing for a declarative option for the Web Share API in the shape of button type=“share”. It’s been an interesting window into the world of web standards.

The story so far…

That’s the situation currently. The general consensus seems to be that it’s probably too soon to be talking about implementation at this stage—the Web Share API itself is still pretty new—but gathering data to inform future work is good.

In planning for the next TPAC meeting (the big web standards gathering), Marcos summarised the situation like this:

Not blocking: but a proposal was made by @adactio to come up with a declarative solution, but at least two implementers have said that now is not the appropriate time to add such a thing to the spec (we need more implementation experience + and also to see how devs use the API) - but it would be great to see a proposal incubated at the WICG.

Now this where things can get a little confusing because it used to be that if you wanted to incubate a proposal, you’d have to do on Discourse, which is a steaming pile of crap that requires JavaScript in order to put text on a screen. But Šime pointed out that proposals can now be submitted on Github.

So that’s where I’ve submitted my proposal, linking through to the explainer document.

Like I said, I’m not expecting anything to happen anytime soon, but it would be really good to gather as much data as possible around existing usage of the Web Share API. If you’re using it, or you know anyone who’s using it, please, please, please take a moment to provide a quick description. And if you could help spread the word to get that issue in front of as many devs as possible, I’d be very grateful.

(Many thanks to everyone who’s already contributed to that issue—much appreciated!)

The reason for a share button type

If you’re at all interested in what I wrote about a declarative Web Share API—and its sequel, a polyfill for button type=”share”—then you might be interested in an explainer document I’ve put together.

It’s a useful exercise for me to enumerate the reasoning for button type=“share” in one place. If you have any feedback, feel free to fork it or create an issue.

The document is based on my initial blog posts and the discussion that followed in this issue on the repo for the Web Share API. In that thread I got some pushback from Marcos. There are three points he makes. I think that two of them lack merit, but the third one is actually spot on.

Here’s the first bit of pushback:

Apart from placing a button in the content, I’m not sure what the proposal offers over what (at least one) browser already provides? For instance, Safari UI already provides a share button by default on every page

But that is addressed in the explainer document for the Web Share API itself:

The browser UI may not always be available, e.g., when a web app has been installed as a standalone/fullscreen app.

That’s exactly what I wanted to address. Browser UI is not always available and as progressive web apps become more popular, authors will need to provide a way for users to share the current URL—something that previously was handled by browsers.

That use-case of sharing the current page leads nicely into the second bit of pushback:

The API is specialized… using it to share the same page is kinda pointless.

But again, the explainer document for the Web Share API directly contradicts this:

Sharing the page’s own URL (a very common case)…

Rather than being a difference of opinion, this is something that could be resolved with data. I’d really like to find out how people are currently using the Web Share API. How much of the current usage falls into the category of “share the current page”? I don’t know the best way to gather this data though. If you have any ideas, let me know. I’ve started an issue where you can share how you’re using the Web Share API. Or if you’re not using the Web Share API, but you know someone who is, please let them know.

Okay, so those first two bits of pushback directly contradict what’s in the explainer document for the Web Share API. The third bit of pushback is more philosophical and, I think, more interesting.

The Web Share API explainer document does a good job of explaining why a declarative solution is desirable:

The link can be placed declaratively on the page, with no need for a JavaScript click event handler.

That’s also my justification for having a declarative alternative: it would be easier for more people to use. I said:

At a fundamental level, declarative technologies have a lower barrier to entry than imperative technologies.

But Marcos wrote:

That’s demonstrably false and a common misconception: See OWL, XForms, SVG, or any XML+namespace spec. Even HTML is poorly understood, but it just happens to have extremely robust error recovery (giving the illusion of it being easy). However, that’s not a function of it being “declarative”.

He’s absolutely right.

It’s not so much that I want a declarative option—I want an option that has robust error recovery. After all, XML is a declarative language but its error handling is as strict as an imperative language like JavaScript: make one syntactical error and nothing works. XML has a brittle error-handling model by design. HTML and CSS have extremely robust error recovery by design. It’s that error-handling model that gives HTML and CSS their robustness.

I’ve been using the word “declarative” when I actually meant “robust in handling errors”.

I guess that when I’ve been talking about “a declarative solution”, I’ve been thinking in terms of the three languages parsed by browsers: HTML, CSS, and JavaScript. Two of those languages are declarative, and those two also happen to have much more forgiving error-handling than the third language. That’s the important part—the error handling—not the fact that they’re declarative.

I’ve been using “declarative” as a shorthand for “either HTML or CSS”, but really I should try to be more precise in my language. The word “declarative” covers a wide range of possible languages, and not all of them lower the barrier to entry. A declarative language with a brittle error-handling model is as daunting as an imperative language.

I should try to use a more descriptive word than “declarative” when I’m describing HTML or CSS. Resilient? Robust?

With that in mind, button type=“share” is worth pursuing. Yes, it’s a declarative option for using the Web Share API, but more important, it’s a robust option for using the Web Share API.

I invite you to read the explainer document for a share button type and I welcome your feedback …especially if you’re currently using the Web Share API!

A polyfill for button type=”share”

After writing about a declarative Web Share API here yesterday I thought I’d better share the idea (see what I did there?).

I opened an issue on the Github repo for the spec.

(I hope that’s the right place for this proposal. I know that in the past ideas were kicked around on the Discourse site for Web platform Incubator Community Group but I can’t stand Discourse. It literally requires JavaScript to render anything to the screen even though the entire content is text. If it turns out that that is the place I should’ve posted, I guess I’ll hold my nose and do it using the most over-engineered reinvention of the browser I’ve ever seen. But I believe that the plan is for WICG to migrate proposals to Github anyway.)

I also realised that, as the JavaScript Web Share API already exists, I can use it to polyfill my suggestion for:

<button type="share">

The polyfill also demonstrates how feature detection could work. Here’s the code.

This polyfill takes an Inception approach to feature detection. There are three nested levels:

  1. This browser supports button type="share". Great! Don’t do anything. Otherwise proceed to level two.
  2. This browser supports the JavaScript Web Share API. Use that API to share the current page URL and title. Otherwise proceed to level three.
  3. Use a mailto: link to prefill an email with the page title as the subject and the URL in the body. Ya basic!

The idea is that, as long as you include the 20 lines of polyfill code, you could start using button type="share" in your pages today.

I’ve made a test page on Codepen. I’m just using plain text in the button but you could use a nice image or SVG or combination. You can use the Codepen test page to observe two of the three possible behaviours browsers could exhibit:

  1. A browser supports button type="share". Currently that’s none because I literally made this shit up yesterday.
  2. A browser supports the JavaScript Web Share API. This is Safari on Mac, Edge on Windows, Safari on iOS, and Chrome, Samsung Internet, and Firefox on Android.
  3. A browser supports neither button type="share" nor the existing JavaScript Web Share API. This is Firefox and Chrome on desktop (and Edge if you’re on a Mac).

See the Pen Polyfill for button type=”share" by Jeremy Keith (@adactio) on CodePen.

The polyfill doesn’t support Internet Explorer 11 or lower because it uses the DOM closest() method. Feel free to fork and rewrite if you need to support old IE.

A declarative Web Share API

I’ve written about the Web Share API before. It’s a handy little bit of JavaScript that—if supported—brings up a system-level way of sharing a page. Seeing as it probably won’t be long before we won’t be able to see full URLs in browsers anymore, it’s going to fall on us as site owners to provide this kind of fundamental access.

Right now the Web Share API exists entirely in JavaScript. There are quite a few browser APIs like that, and it always feels like a bit of a shame to me. Ideally there should be a JavaScript API and a declarative option, even if the declarative option isn’t as powerful.

Take form validation. To cover the most common use cases, you probably only need to use declarative markup like input type="email" or the required attribute. But if your use case gets a bit more complicated, you can reach for the Constraint Validation API in JavaScript.

I like that pattern. I wish it were an option for JavaScript-only APIs. Take the Geolocation API, for example. Right now it’s only available through JavaScript. But what if there were an input type="geolocation" ? It wouldn’t cover all use cases, but it wouldn’t have to. For the simple case of getting someone’s location (like getting someone’s email or telephone number), it would do. For anything more complex than that, that’s what the JavaScript API is for.

I was reminded of this recently when Ada Rose Cannon tweeted:

It really feels like there should be a semantic version of the share API, like a mailto: link

I think she’s absolutely right. The Web Share API has one primary use case: let the user share the current page. If that use case could be met in a declarative way, then it would have a lower barrier to entry. And for anyone who needs to do something more complicated, that’s what the JavaScript API is for.

But Pete LePage asked:

How would you feature detect for it?

Good question. With the JavaScript API you can do feature detection—if the API isn’t supported you can either bail or provide your own implementation.

There a few different ways of extending HTML that allow you to provide a fallback for non-supporting browsers.

You could mint a new element with a content model that says “Browsers, if you do support this element, ignore everything inside the opening and closing tags.” That’s the way that the canvas element works. It’s the same for audio and video—they ignore everything inside them that isn’t a source element. So developers can provide a fallback within the opening and closing tags.

But forging a new element would be overkill for something like the Web Share API (or Geolocation). There are more subtle ways of extending HTML that I’ve already alluded to.

Making a new element is a lot of work. Making a new attribute could also be a lot of work. But making a new attribute value might hit the sweet spot. That’s why I suggested something like input type="geolocation" for the declarative version of the Geolocation API. There’s prior art here; this is how we got input types for email, url, tel, color, date, etc. The key piece of behaviour is that non-supporting browsers will treat any value they don’t understand as “text”.

I don’t think there should be input type="share". The action of sharing isn’t an input. But I do think we could find an existing HTML element with an attribute that currently accepts a list of possible values. Adding one more value to that list feels like an inexpensive move.

Here’s what I suggested:

<button type=”share” value=”title,text”>

For non-supporting browsers, it’s a regular button and needs polyfilling, no different to the situation with the JavaScript API. But if supported, no JS needed?

The type attribute of the button element currently accepts three possible values: “submit”, “reset”, or “button”. If you give it any other value, it will behave as though you gave it a type of “submit” or “button” (depending on whether it’s in a form or not) …just like an unknown type value on an input element will behave like “text”.

If a browser supports button type="share”, then when the user clicks on it, the browser can go “Right, I’m handing over to the operating system now.”

There’s still the question of how to pass data to the operating system on what gets shared. Currently the JavaScript API allows you to share any combination of URL, text, and description.

Initially I was thinking that the value attribute could be used to store this data in some kind of key/value pairing, but the more I think about it, the more I think that this aspect should remain the exclusive domain of the JavaScript API. The declarative version could grab the current URL and the value of the page’s title element and pass those along to the operating system. If you need anything more complex than that, use the JavaScript API.

So what I’m proposing is:

<button type="share">

That’s it.

But how would you test for browser support? The same way as you can currently test for supported input types. Make use of the fact that an element’s attribute value and an element’s property value (which 99% of the time are the same), will be different if the attribute value isn’t supported:

var testButton = document.createElement("button");
testButton.setAttribute("type","share");
if (testButton.type != "share") {
// polyfill
}

So that’s my modest proposal. Extend the list of possible values for the type attribute on the button element to include “share” (or something like that). In supporting browsers, it triggers a very bare-bones handover to the OS (the current URL and the current page title). In non-supporting browsers, it behaves like a button currently behaves.

The land before modern APIs – Increment: APIs

This is a wonderful tale of spelunking into standards from Darius Kazemi—I had no idea that HTTP status codes have their origin in a hastily made decision in the days of ARPANET.

20 people got together at MIT in 1972 for a weekend workshop. On the second day, a handful of people in a breakout session decided it would be a good idea to standardize error messages between two services for transferring data, even though those two services had not necessarily planned to speak to one another. One thing led to another, and now 404 is synonymous with “I can’t find the thing.”

This story is exactly the kind of layering of technologies that I was getting at in the first chapter of Resilient Web Design.

HTTP status codes are largely an accident of history. The people who came up with them didn’t plan on defining a numerical namespace that would last half a century or work its way into popular culture. You see this pattern over and over in the history of technology.

Revisiting Adaptive Design, a lost design movement (Interconnected)

Marxian Alienation And Web Development: HeydonWorks

As a web designer or developer burnout comes calling when you try to do good work, but you’re not allowed.

  • You want to make the app more performant; your boss wants to fill it full of third party trackers
  • You want to make the app more accessible; your boss wants you to focus on the ‘able market’ instead
  • You want to word the app more clearly; your boss wants to trick users with misleading language
