Directory enquiries

I was having a discussion with some of my peers a little while back. We were collectively commenting on the state of education and documentation for front-end development.

A lot of the old stalwarts have fallen by the wayside of late. CSS Tricks hasn’t been the same since it got bought out by Digital Ocean. A List Apart goes through fallow periods. Even the Mozilla Developer Network is looking to squander its trust by adding inaccurate “content” generated by a large language model.

The most obvious solution is to start up a brand new resource for front-end developers. But there are two probems with that:

  1. It’s really, really, really hard work, and
  2. It feels a bit 927.

I actually think there are plenty of good articles and resources on front-end development being published. But they’re not being published in any one specific place. People are publishing them on their own websites.

Ahmed, Josh, Stephanie, Andy, Lea, Rachel, Robin, Michelle …I could go on, but you get the picture.

All this wonderful stuff is distributed across the web. If you have a well-stocked RSS reader, you’re all set. But if you’re new to front-end development, how do you know where to find this stuff? I don’t think you can rely on search, unless you have a taste for slop.

I think the solution lies not with some hand-wavey “AI” algorithm that burns a forest for every query. I think the solution lies with human curation.

I take inspiration from Phil’s fantastic project, ooh.directory. Imagine taking that idea of categorisation and applying it to front-end dev resources.

Whether it’s a post on web.dev, Smashing Magazine, or someone’s personal site, it could be included and categorised appropriately.

Now, there would still be a lot of work involved, especially in listing and categorising the articles that are already out there, but it wouldn’t be nearly as much work as trying to create those articles from scratch.

I don’t know what the categories should be. Does it make sense to have top-level categories for HTML, CSS, and JavaScript, with sub-directories within them? Or does it make more sense to categorise by topics like accessibility, animation, and so on?

And this being the web, there’s no reason why one article couldn’t be tagged to simultaneously live in multiple categories.

There’s plenty of meaty information architecture work to be done. And there’d be no shortage of ongoing work to handle new submissions.

A stretch goal could be the creation of “playlists” of hand-picked articles. “Want to get started with CSS grid layout? Read that article over there, watch this YouTube video, and study this page on MDN.”

What do you think? Does this one-stop shop of hyperlinks sound like it would be useful? Does it sound feasible?

I’m just throwing this out there. I’d love it if someone were to run with it.

Speculation rules

There’s a new addition to the latest version of Chrome called speculation rules. This already existed before with a different syntax, but the new version makes more sense to me.

Notice that I called this an addition, not a standard. This is not a web standard, though it may become one in the future. Or it may not. It may wither on the vine and disappear (like most things that come from Google).

The gist of it is that you give the browser one or more URLs that the user is likely to navigate to. The browser can then pre-fetch or even pre-render those links, making that navigation really snappy. It’s a replacement for the abandoned link rel="prerender".

Because this is a unilateral feature, I’m not keen on shipping the code to all browsers. The old version of the API required a script element with a type value of “speculationrules”. That doesn’t do any harm to browsers that don’t support it—it’s a progressive enhancement. But unlike other progressive enhancements, this isn’t something that will just start working in those other browsers one day. I mean, it might. But until this API is an actual web standard, there’s no guarantee.

That’s why I was pleased to see that the new version of the API allows you to use an external JSON file with your list of rules.

I say “rules”, but they’re really more like guidelines. The browser will make its own evaluation based on bandwidth, battery life, and other factors. This feature is more like srcset than source: you give the browser some options, but ultimately you can’t force it to do anything.

I’ve implemented this over on The Session. There’s a JSON file called speculationrules.js with the simplest of suggestions:

{
  "prerender": [{
    "where": {
        "href_matches": "/*"
    },
    "eagerness": "moderate"
  }]
}

The eagerness value of “moderate” says that any link can be pre-rendered if the user hovers over it for 200 milliseconds (the nuclear option would be to use a value of “immediate”).

I still need to point to that JSON file from my HTML. Usually this would be done with something like a link element, but for this particular API, I can send a response header instead:

Speculation-Rules: “/speculationrules.json"

I like that. The response header is being sent to every browser, regardless of whether they support speculation rules or not, but at least it’s just a few bytes. Those other browsers will ignore the header—they won’t download the JSON file.

Here’s the PHP I added to send that header:

header('Speculation-Rules: "/speculationrules.json"');

There’s one extra thing I had to do. The JSON file needs to be served with mime-type of “application/speculationrules+json”. Here’s how I set that up in the .conf file for The Session on Apache:

<IfModule mod_headers.c>
  <FilesMatch "speculationrules.json">
    Header set Content-type application/speculationrules+json
   </FilesMatch>
</IfModule>

A bit of a faff, that.

You can see it in action on The Session. Open up Chrome or Edge (same same but different), fire up the dev tools and keep the network tab open while you navigate around the site. Notice how hovering over a link will trigger a new network request. Clicking on that link will get you that page lickety-split.

Mind you, in the case of The Session, the navigations were already really fast—performance is a feature—so it’s hard to guage how much of a practical difference it makes in this case, but it still seems like a no-brainer to me: taking a few minutes to add this to your site is worth doing.

Oh, there’s one more thing to be aware of when you’re implementing speculation rules. You have the option of excluding URLs from being pre-fetched or pre-rendered. You might need to do this if you’ve got links for adding items to shopping carts, or logging the user out. But my advice would instead be: stop using GET requests for those actions!

Most of the examples given for unsafe speculative loading conditions are textbook cases of when not to use links. Links are for navigating. They’re indempotent. For everthing else, we’ve got forms.

Indie webbing

The past weekend’s Indie Web Camp Brighton was wonderful! Many thanks to Mark and Paul for all their work putting it together.

There was a great turn-out. It felt like the perfect time for an Indie Web Camp. There’s a real appetite for getting away from ever more extractive silos and staking claim to our own corners of the web. Most of the attendees were at their first ever Indie Web Camp.

Paul asked me to oversee the schedule planning on day one, which I was happy to do. We made sure that first-timers got first dibs on proposing sessions. In the end, every single session was proposed by new attendees.

Day two was all about putting ideas into practice: coding, designing, and writing on our own website. I’m always blown away by how much gets done in just one short day. Best of all is when there’s someone who starts the weekend without their own website but finishes with a live site. That happened again this time.

I spent the second day tinkering with something I started at Indie Web Camp Nuremberg in October. Back then, I got related posts working here on my journal; a list of suggested follow-up posts to read based on the tags of the current post.

I wanted to do the same for my links; show links related to the one I’m currently linking to. It didn’t take too long to get that up and running.

But then I thought about it some more and realised it would be good to also show blog posts related to the link. So I did that. Then I realised it would be really good to show related links under blog posts too.

So now, if everything’s working correctly, then at the end of this post you will not only see related blog posts I’ve previously written, but also links related to the content of this post.

It was a very inspiring weekend. There’s something about being in a room with other people working on their websites that makes me super productive.

While we were hacking away on day two, somebody mentioned that they still find hard to explain the indie web to people.

“It’s having your own website”, I said.

But surely there’s more to it than that, they wondered.

Nope. If someone has their own website, then they’re part of the indie web. It doesn’t matter if that website is made with a complicated home-rolled tech stack or if it’s a Squarespace site.

What you do with your own website is entirely up to you. The technologies are just plumbing wether it’s webmentions, RSS, or anything else. None of it is a requirement. Heck, even HTML is optional. If you want to put plain text files on your website, go for it. It’s your website.

Linking

One of the first ever personal websites—long before the word “blog” was a mischievous gleam in Peter’s eye—was Justin Hall’s links.net. Linking was right there in the domain name.

I really enjoy sharing links on my website. It feels good to point to something and say, “Hey, check this out!”

Other people are doing it too.

Then there are some relatively new additions to the linking gang:

There are more out there for you to discover and add to your feed reader of choice. Good link hunting!

Stuck in the dock

I was impressed with how Safari now allows you to add websites to the dock:

It feels great to have websites that act just like other apps. I like that some of the icons in my dock are native, some are web apps, and I mostly don’t notice the difference.

Trys liked it too:

For all intents and purposes, this is a desktop application created without a single line of Swift or Objective-C, or any heavy Electron wrappers.

Oh, and the application can work offline! Service workers, and browser storage are more than stable enough to handle a variety of offline loading patterns. These are truly exciting times to be building for the web!

There was one aspect that I was particularly pleased with. External links:

Links within a Safari-installed web app respect your default browser choice.

Excellent! Except it’s no longer true. At least not in some cases. The behaviour is inconsisent but I’m running the latest version of Safari on the latest version of Sonoma, and now external links in a Safari-installed web app are broken. They just stay in the same application.

I thought maybe it was related to whether the website’s manifest file has the display value set to “standalone” rather than, say, “minimal ui”. Maybe the “standalone” instruction is being taken literally? But even when I change the value I’m still getting the broken behaviour.

This may sound like a small thing, but it completely changes the feel of using the web app. Instead of feeling like “I’m using an app that just happens to be on the web”, it now feels like “I’m using a web browser but with fewer features.”

I’ve been loving having Mastodon as a standalone app in my dock. It used to be that if I clicked on a link in a Mastodon post, it would open in my browser of choice (Firefox) where I could then bookmark it, or do any other tasks that my browser offers me. Now if I click on a link in Mastodon, I’m stuck in the same “app”. It feels horribly stifling.

I can right-click on a link and get options that still keep me in the same app, like “Open link” or “Open Link in New Window.” To actually open the link in my web browser, I have to select “Copy Link”, then go to my web browser, open a new tab, and paste the link in there.

This is broken. I hope it isn’t intentional. Maybe I’m just at the receiving end of some weird glitch. If this stays this way, I’ll probably just remove the Safari-installed web apps from my dock. They feel pointless if they’re just roach motels.

I’d love to file a bug for this, but this isn’t a Webkit bug, it’s a Safari bug (and the Webkit bug tracker is at pains to point out that Webkit and Safari are not the same thing). But have you ever tried to file a bug with Apple? Good luck!

Anyway, I sincerely hope that this change will be walked back. Otherwise websites in the dock are dead in the water.

In the margins

John Willshire has been pondering web marginilia AKA stuff you put in your sidebar.

He has a particular fondness for the good ol’ blogroll. I’ve still got my analogue equivalent on my homepage—the bedroll. It’s a list of links to people who’ve stayed over. Maybe I should also have a regular blogroll, but I suspect it would just be a reproduction of feeds I’m subscribed to.

Then there’s marginalia at the level of a blog post, rather than a whole blog. Kevin Marks points out that this is something that Vannevar Bush described his theoretical memex doing—a device I was just talking about. Kevin created a proof of concept showing outbound and inbound links.

Outbound links are annoted versions of the A elements in a blog post. Inbound links are webmentions (which should now include this post of mine).

Kevin has those links in the margins on either side of the blog post. I’ve also got links that go with my blog posts, but they’re displayed linearly:

  1. the post itself,
  2. any responses (webmentions),
  3. related posts, something I only recently added, and
  4. posts from the same day further back in time.

Do they still count as marginalia when they’re presented vertically rather than alongside? For mobile devices, I’m not sure there’s any alternative.

Indie Web Camp Nuremberg

After two days at border:none in Nuremberg, it was time for two days at Indie Web Camp, also in Nuremberg.

I hadn’t been to an Indie Web Camp since before The Situation. It felt very good to be back. I had almost forgotten how inspiring and productive they can be.

This one had a good turnout of around twenty people. We had ourselves an excellent first day of thought-provoking sessions. Then on day two it was time to put some of those ideas into action.

A little trick I like to do on the practical day is to have two tasks to attempt: one of them quite simple, and the other more ambitious. That way, as long as I get the simpler task done, I’ll always have at least something to demo at the end of the day.

This time I attempted three bits of home improvement on my website.

Autolinking Mastodon usernames

The first problem I set myself was ostensibly the simple one. But it involved regular expressions, so then I had two problems.

I wanted to automatically link up Mastodon usernames if I mentioned one in my notes. For example, during border:none I mentioned Brian’s mastodon username in a note: @briansuda@loðfíll.is.

That turned out to be an excellent test case. Those Icelandic characters made sure I wasn’t making unwarranted assumptions about character sets.

Here’s the regular expression I came up with. It’s not foolproof by any means. Basically it looks for @[email protected].

Good enough. Ship it.

Related posts

My next task was a bit more ambitious. It involved SQL queries, something I’m slightly better at than regular expressions but that’s a very low bar.

I wanted to show related posts when you get to the end of one of my blog posts.

I’ve been tagging all my blog posts for years so that’s the mechanism I used for finding similar posts. There’s probably a clever SQL statement that could do this, but I ended up brute-forcing it a bit.

I don’t feel too bad about the hacky clunky nature of my solution, because I cache blog post pages. That means only the first person to view the blog post (usually me) will suffer any performance impacts from my clunky database queries. After that everything’s available straight from a cached file.

Let’s say you’re reading a blog post of mine that I’ve tagged with ten different keywords. I make a separate SQL query for each keyword to get all the other posts that use that tag. Then it’s a matter of sorting through all the results.

I loop through the results of each tag and apply a score to the tagged post. If the post shares one tag with the post you’re looking at, it has a score of one. If it shares two tags, it has a score of two, and so on.

I decided that for a post to be considered related, it had to share at least three tags. I also decided to limit the list of related posts to a maximum of five.

It worked out pretty well. If you scroll down on my recent post about JavaScript, you’ll see links to related posts about JavaScript. If you read through a post on accessibility testing, you’ll find other posts about accessibility testing. If you make it to the end of this post about Mars colonisation you’ll see links to more posts about exploring our solar system.

Right now I’m just doing this for my blog but I’d like to do it for my links too. A job for a future Indie Web Camp.

Link rot

I was very inspired by Remy’s recent post on how he’s tackling link rot on his site. I wanted to do the same for mine.

On the first day at Indie Web Camp I led a session on link rot to gather ideas and alternative approaches. We had a really good discussion, though it’s always worth bearing in mind that there’ll never be a perfect solution. There’ll always be some false positives and some false negatives.

The other Jeremy at Indie Camp Nuremberg blogged about the session. Sebastian Greger was attending remotely and the session inspired him to spend the second day also tackling linkrot.

In the end I decided to stick with Remy’s two-pronged approach:

  1. a client-side script that—as a progressive enhancement—intercepts outbound links and re-routes them to
  2. a server-side script that redirects to the Internet Archive if the link is broken.

Here’s the JavaScript I wrote for the first part.

It’s very similar to Remy’s but with one little addition. I check to see if the clicked link is inside an h-entry and if it is, I pass on the date from the post’s dt-published value.

Here’s the PHP I wrote for the server-side redirector. The comments tell the story of what the code is doing:

  • Check that the request is coming from my site.
  • There also has to be a URL provided in the query string.
  • Make a very quick curl request to get the response headers from the URL. The time limit is set to 1 second.
  • If there was any error (like a time out), give up and go to the URL.
  • Pick the response headers apart to get the HTTP status code.
  • If the response is OK, go to the URL.
  • If the response is a redirect, go around again but this time use the redirect URL.
  • Construct the archive.org search endpoint.
  • If we have a date, provide it. Otherwise ask for the latest snapshot.
  • Ping that archive.org URL. This time there’s no time limit; this might take a while.
  • If there’s an archived copy, redirect to that.
  • There’s no archived copy. Give up and go the URL anyway.

Not perfect by any means, but it works for the most common cases of link rot.

For the demo at the end of the day I went back into my archive of over 10,000 links and plucked out some old posts, like this one from December 2005. It takes a little while to do the rerouting but eventually you get to see the archived version from the same time period as when I linked to it.

Here’s another link from 2005. Here’s another. Those links are broken now, but with a little patience, you’ll still get to read them on the Internet Archive.

The Internet Archive’s wayback machine really is a gift. I can’t imagine how would it be even remotely possible to try to address link rot on my site without archive.org.

I will continue to donate money to the Internet Archive and I encourage you to do the same.

Multi-page web apps

I received this email recently:

Subject: multi-page web apps

Hi Jeremy,

lately I’ve been following you through videos and texts and I’m curious as to why you advocate the use of multi-page web apps and not single-page ones.

Perhaps you can refer me to some sources where your position and reasoning is evident?

Here’s the response I sent…

Hi,

You can find a lot of my reasoning laid out in this (short and free) online book I wrote called Resilient Web Design:

https://resilientwebdesign.com/

The short answer to your question is this: user experience.

The slightly longer answer…

For most use cases, a website (or multi-page app if you prefer) is going to provide the most robust experience for the most number of users. That’s because a user’s web browser takes care of most of the heavy lifting.

Navigating from one page to another? That’s taken care of with links.

Gathering information from a user to process on a server? That’s taken care of with forms.

This frees me up to concentrate on the content and the design without having to reinvent the wheels of links and form fields.

These (let’s call them) multi-page apps are stateless, and for most use cases that’s absolutely fine.

There are some cases where you’d want a state to persist across pages. Let’s say you’re playing a song, or a podcast episode. Ideally you’d want that player to continue seamlessly playing even as the user navigates around the site. In that situation, a single-page app would be a suitable architecture.

But that architecture comes at a cost. Now you’ve got stop the browser doing what it would normally do with links and forms. It’s up to you to recreate that functionality. And you can’t do it with HTML, a robust fault-tolerant declarative language. You need to reimplement all that functionality in JavaScript, a less tolerant, more brittle language.

Then you’ve got to ship all that code to the user before they can use your site. It might be JavaScript code you’ve written yourself or it might be a third-party library designed for building single-page apps. Either way, the user pays a download tax (and a parsing tax, and an execution tax). Whereas with links and forms, all of that functionality is pre-bundled into the user’s web browser.

So that’s my reasoning. At least nine times out of ten, a multi-page approach is leaner, more robust, and simpler.

Like I said, there are times when a single-page approach makes sense—it all comes down to whether state needs to be constantly preserved. But these use cases are the exceptions, not the rule.

That’s why I find the framing of your question a little concerning. It should be inverted. The default approach should be to assume a multi-page approach (which is the way the web works by default). Deciding to take a JavaScript-driven single-page approach should be the exception.

It’s kind of like when people ask, “Why don’t you have children?” Surely the decision to have a child should require deliberation and commitment, rather than the other way around.

When it comes to front-end development, I’m worried that we’ve reached a state where the more complex over-engineered approach is viewed as the default.

I may be committing a fundamental attribution error here, but I think that we’ve reached this point not because of any consideration for users, but rather because of how it makes us developers feel. Perhaps building an old-fashioned website that uses HTML for navigations feels too easy, like it’s beneath us. But building an “app” that requires JavaScript just to render text on a screen feels like real programming.

I hope I’m wrong. I hope that other developers will start to consider user experience first and foremost when making architectural decisions.

Anyway. That’s my answer. User experience.

Cheers,

Jeremy

Accessibility audits for all

It’s often said that it’s easier to make a fast website than it is to keep a website fast. Things slip through. If you’re not vigilant, performance can erode without you noticing.

It’s a similar story for other invisible but important facets of your website: privacy, security, accessibility. Because they’re hidden from view, you won’t be able to see if there’s a regression.

That’s why it’s a good idea to have regular audits for performance, privacy, security, and accessibility.

I wrote about accessibility testing a while back, and how there’s quite a bit that you can do for yourself before calling in an expert to look at the really gnarly stuff:

When you commission an accessibility audit, you want to make sure you’re getting the most out of it. Don’t squander it on issues that you can catch and fix yourself. Make sure that the bulk of the audit is being spent on the specific issues that are unique to your site.

I recently did an internal audit of the Clearleft website. After writing up the report, I also did a lunch’n’learn to share my methodology. I wanted to show that there’s some low-hanging fruit that pretty much anyone can catch.

To start with, there’s keyboard navigation. Put your mouse and trackpad to one side and use the tab key to navigate around.

Caveat: depending on what browser you’re using, you might need to update some preferences for keyboard navigation to work on links. If you’re using Safari, go to “Preferences”, then “Advanced”, and tick “Press Tab to highlight each item on a web page.”

Tab around and find out. You should see some nice chunky :focus-visible styles on links and form fields.

Here’s something else that anyone can do: zoom in. Increase the magnification to 200%. Everything should scale proportionally. How about 500%? You’ll probably see a mobile-friendly layout. That’s fine. As long as nothing is broken or overlapping, you’re good.

At this point, I reach for some tools. I’ve got some bookmarklets that do similar things: tota11y and ANDI. They both examine the source HTML and CSS to generate reports on structure, headings, images, forms, and so on.

These tools are really useful, but you need to be able to interpret the results. For example, a tool can tell you if an image has no alt text. But it can’t tell you if an image has good or bad alt text.

Likewise, these tools are great for catching colour-contrast issues. But there’s a big difference between a colour-contrast issue on the body copy compared to a colour-contrast issue on one unimportant page element.

I think that demonstrates the most important aspect of any audit: prioritisation.

Finding out that you have accessibility issues isn’t that useful if they’re all presented as an undifferentiated list. What you really need to know are which issues are the most important to fix.

By the way, I really like the way that the Gov.uk team prioritises accessibility concerns:

The team puts accessibility concerns in 2 categories:

  1. Theoretical: A question or statement regarding the accessibility of an implementation within the Design System without evidence of real-world impact.
  2. Evidenced: Sharing new research, data or evidence showing that an implementation within the Design System could cause barriers for disabled people.

The team will usually prioritise evidenced issues and queries over theoretical ones.

When I wrote up my audit for the Clearleft website, I structured it in order of priority. The most important things to fix are at the start of the audit. I also used a simple scale for classifying the severity of issues: low, medium, and high priority.

Thankfully there were no high-priority issues. There were a couple of medium-priority issues. There were plenty of low-priority issues. That’s okay. That’s a pretty good distribution.

If you’re interested, here’s the report I delivered…

Accessibility audit on clearleft.com

Colour contrast

There are a few issues with the pink colour. When it’s used on a grey background, or when it’s used as a background colour for white text, the colour contrast isn’t high enough.

The SVG arrow icon could be improved too.

Recommendations

Medium priority
  • Change the pink colour universally to be darker. The custom property --red is currently rgb(234, 33, 90). Change it to rgb(210, 20, 73) (thanks, James!)
Low priority
  • The SVG arrow icon currently uses currentColor. Consider hardcoding solid black (or a very, very dark grey) instead.

Images

Alt text is improving on the site. There’s reasonable alt text at the top level pages and the first screen’s worth of case studies and blog posts. I made a sweep through these pages a while back to improve the alt text but I haven’t done older blog posts and case studies.

Recommendations

Medium priority
  • Make a sweep of older blog posts and case studies and fix alt text.
Low priority
  • Images on the contact page have alt text that starts with “A photo of…” — this is redundant and can be removed.

Headings

The site is using headings sensibly. Sometimes the nesting of headings isn’t perfect, but this is a low priority issue. For example, on the contact page there’s an h1 followed by two h3s. In theory this isn’t correct. In practice (for screen reader users) it’s not an issue.

Recommendations

Low priority
  • On the home page, “UX London 2023” should probably be h3 instead of h1.
  • On the case studies index page we’re currently using h3 headings for the industry sector (“Charities”, “Education” etc.) but these should probably not be headings at all. On the blog index page we use a class “Tags” for a similar purpose. Consider reusing that pattern on the case studies index page.
  • On the about index page, “We’re driven to be” is an h3 and the subsequent three headings are h2s. Ideally this would be reversed: a single h2 followed by three h3s.

Link text

Sometimes the same text is used for different links.

Recommendations

Low priority
  • On the home page the text “Read the case study” is re-used for multiple links. It would be better if each link were different e.g. “Read about The Natural History Museum.”

Forms

The only form on the site is the newsletter sign-up form. It’s marked up pretty well: the input has an associated label, although a visible (clickable) label would be better.

Tabbing order

The site doesn’t use JavaScript to mess with tabbing order for keyboard users. The source order of elements in the markup generally makes sense so all is good.

The focus styles are nice and clear too!

Structure

The site is using HTML landmark elements sensibly (header, nav, main, footer, etc.).

Tweaking navigation labelling

I’ve always liked the idea that your website can be your API. Like, you’ve already got URLs to identify resources, so why not make that URL structure predictable and those resources parsable?

That’s why the (read-only) API for The Session doesn’t live at a separate subdomain. It uses the same URL structure as the regular site, but you can request the resources in an alternative format: JSON, XML, RSS.

This works out pretty well, mostly because I put a lot of thought into the URL structure of the site. I’m something of a URL fetishist, but I think that taking a URL-first approach to information architecture can be a good exercise.

Most of the resources on The Session involve nouns like tunes, events, discussions, and so on. There’s a consistent and predictable structure to the URLs for those sections:

  • /things
  • /things/new
  • /things/search

And then an idividual item can be found at:

  • things/ID

That’s all nice and predictable and the naming of the URLs matches what you’d expect to find:

Tunes, events, discussions, sessions. Those are all fine. But there’s one section of the site that has this root URL:

/recordings

When I was coming up with the URL structure twenty years ago, it was clear what you’d find there: track listings for albums of music. No one would’ve expected to find actual recordings of music available to listen to on-demand. The bandwidth constraints and technical limitations of the time made that clear.

Two decades on, the situation has changed. Now someone new to the site might well expect to hit a link called “recordings” and expect to hear actual recordings of music.

So I should probably change the label on the link. I don’t think “albums” is quite right—what even is an album any more? The word “discography” is probably the most appropriate label.

Here’s my dilemma: if I update the label, should I also update the URL structure?

Right now, the section of the site with /tunes URLs is labelled “tunes”. The section of the site with /events URLs is labelled “events”. Currently the section of the site with /recordings URLs is labelled “recordings”, but may soon be labelled “discography”.

If you click on “tunes”, you end up at /tunes. But if you click on “discography”, you end up at /recordings.

Is that okay? Am I the only one that would be bothered by that?

I could update the URLs to match the labelling (with redirects for the old URLs, of course), but I’m not so keen on this URL structure:

  • /discography
  • /discography/new
  • /discography/search
  • /discography/ID

It doesn’t seem as tidy as:

  • /recordings
  • /recordings/new

But if I don’t update the URLs to match the label, then I’m just going to have to live with the mismatch.

I’m just thinking out loud here. I think I should definitely update the label. I just won’t make any decision on changing URLs for a while yet.

Links for Declarative Design

At the end of next week, I will sally forth to California. I’m going to wend my way to San Francisco where I will be speaking at An Event Apart.

I am very much looking forward to speaking at my first in-person AEAs in exactly three years. That was also in San Francisco, right before The Situation.

I hope to see you there. There are still tickets available.

I’ve put together a brand new talk that I’m very excited about. I’ve already written about the prep for this talk:

So while I’ve been feeling somewhat under the gun as I’ve been preparing this new talk for An Event Apart, I’ve also been feeling that the talk is just the culmination; a way of tying together some stuff I’ve been writing about it here for the past year or two.

The talk is called Declarative Design. Here’s the blurb:

Different browsers, different devices, different network speeds…designing for the web can feel like a never-ending battle for control. But what if the solution is to relinquish control? Instead of battling the unknowns, we can lean into them. In the world of programming, there’s the idea of declarative languages: describing what you want to achieve without specifying the exact steps to get there. In this talk, we’ll take this concept of declarative programming and apply it to designing for the web. Instead of focusing on controlling the outputs of the design process, we’ll look at creating the right inputs instead. Leave the final calculations for the outputs to the browser—that’s what computers are good at. We’ll look at CSS features, design systems, design principles, and more. Then you’ll be ready to embrace the fluid, ever-changing, glorious messiness of the World Wide Web!

If you’d a glimpse into the inside of my head while I’ve been preparing this talk, here’s a linkdump of various resources that are either mentioned in the talk or influenced it…

Alternative stylesheets

My website has different themes you can choose from. I don’t just mean a dark mode. These themes all look very different from one another.

I assume that 99.99% of people just see the default theme, but I keep the others around anyway. Offering different themes was originally intended as a way of showcasing the power of CSS, and specifically the separation of concerns between structure and presentation. I started doing this before the CSS Zen Garden was created. Dave really took it to the next level by showing how the same HTML document could be styled in an infinite number of ways.

Each theme has its own stylesheet. I’ve got a very simple little style switcher on every page of my site. Selecting a different theme triggers a page refresh with the new styles applied and sets a cookie to remember your preference.

I also list out the available stylesheets in the head of every page using link elements that have rel values of alternate and stylesheet together. Each link element also has a title attribute with the name of the theme. That’s the standard way to specify alternative stylesheets.

In Firefox you can switch between the specified stylesheets from the View menu by selecting Page Style (notice that there’s also a No style option—very handy for checking your document structure).

Other browsers like Chrome and Safari don’t do anything with the alternative stylesheets. But they don’t ignore them.

Every browser makes a network request for each alternative stylesheet. The request is non-blocking and seems to be low priority, which is good, but I’m somewhat perplexed by the network request being made at all.

I get why Firefox is requesting those stylesheets. It’s similar to requesting a print stylesheet. Even if the network were to drop, you still want those styles available to the user.

But I can’t think of any reason why Chrome or Safari would download the alternative stylesheets.

Speaking at CSS Day 2022

I’m very excited about speaking at CSS Day this year. My talk is called In And Out Of Style:

It’s an exciting time for CSS! It feels like new features are being added every day. And yet, through it all, CSS has managed to remain an accessible language for anyone making websites. Is this an inevitable part of the design of CSS? Or has CSS been formed by chance? Let’s take a look at the history—and some alternative histories—of the World Wide Web to better understand where we are today. And then, let’s cast our gaze to the future!

Technically, CSS Day won’t be the first outing for this talk but it will be the in-person debut. I had the chance to give the talk online last week at An Event Apart. Giving a talk online isn’t quite the same as speaking on stage, but I got enough feedback from the attendees that I’m feeling confident about giving the talk in Amsterdam. It went down well with the audience at An Event Apart.

If the description has you intrigued, come along to CSS Day to hear the talk in person. And if you like the subject matter, I’ve put together these links to go with the talk…

A bug with progressive web apps on iOS

Dave recently wrote some good advice about what to do—and what not to do—when it comes to complaining about web browsers. I wrote something on this topic a little while back:

If there’s something about a web browser that you’re not happy with (or, indeed, if there’s something you’re really happy with), take the time to write it down and publish it

To summarise Dave’s advice, avoid conspiracy theories and snark; stick to specifics instead.

It’s very good advice that I should heed (especially the bit about avoiding snark). In that spirit, I’d like to document what I think is a bug on iOS.

I don’t need to name the specific browser, because there is basically only one browser allowed on iOS. That’s not snark; that’s a statement of fact.

This bug involves navigating from a progressive web app that has been installed on your home screen to an external web view.

To illustrate the bug, I’ll use the example of The Session. If you want to recreate the bug, you’ll need to have an account on The Session. Let me know if you want to set up a temporary account—I can take care of deleting it afterwards.

Here are the steps:

  1. Navigate to thesession.org in Safari on an iOS device.
  2. Add the site to your home screen.
  3. Open the installed site from your home screen—it will launch in standalone mode.
  4. Log in with your username and password.
  5. Using the site menu, navigate to the links section of the site.
  6. Click on any external link.
  7. After the external link opens in a web view, tap on “Done” to close the web view.

Expected behaviour: you are returned to the page you were on with no change of state.

Actual behaviour: you are returned to the page you were on but you are logged out.

So the act of visiting an external link in a web view while in a progressive web app in standalone mode seems to cause a loss of cookie-based authentication.

This isn’t permanent. Clicking on any internal link restores the logged-in state.

It is surprising though. My mental model for opening an external link in a web view is that it sits “above” the progressive web app, which remains in stasis “behind” it. But the page must actually be reloading, either when the web view is opened or when the web view is closed. And that reload is behaving like a fetch event without credentials.

Anyway, that’s my bug report. It may already be listed somewhere on the WebKit Bugzilla but I lack the deductive skills to find it. I’m not even sure if that’s the right place for this kind of bug. It might be specific to the operating system rather than the rendering engine.

This isn’t a high priority bug, but it is one of those cumulatively annoying software paper cuts.

Hope this helps!

Today, the distant future

It’s a bit of a cliché to talk about living in the future. It’s also a bit pointless. After all, any moment after the big bang is a future when viewed from any point in time before it.

Still, it’s kind of fun when a sci-fi date rolls around. Like in 2015 when we reached the time depicted in Back To The Future 2, or in 2019 when we reached the time of Blade Runner.

In 2022 we are living in the future of web standards. Again, technically, we’re always living in the future of any past discussion of web standards, but this year is significant …in a very insignificant way.

It all goes back to 2008 and an interview with Hixie, editor of the HTML5 spec at the WHATWG at the time. In it, he mentioned the date 2022 as the milestone for having two completely interoperable implementations.

The far more important—and ambitious—date was 2012, when HTML5 was supposed to become a Candidate Recommendation, which is standards-speak for done’n’dusted.

But the mere mention of the year 2022 back in the year 2008 was too much for some people. Jeff Croft, for example, completely lost his shit (Jeff had a habit of posting angry rants and then denying that he was angry or ranty, but merely having a bit of fun).

The whole thing was a big misunderstanding and soon irrelevant: talk of 2022 was dropped from HTML5 discussions. But for a while there, it was fascinating to see web designers and developers contemplate a year that seemed ludicriously futuristic. Jeff wrote:

God knows where I’ll be in 13 years. Quite frankly, I’ll be pretty fucking disappointed in myself (and our entire industry) if I’m writing HTML in 13 years.

That always struck me as odd. If I thought like that, I’d wonder what the point would be in making anything on the web to begin with (bear in mind that both my own personal website and The Session are now entering their third decade of life).

I had a different reaction to Jeff, as I wrote in 2010:

Many web developers were disgusted that such a seemingly far-off date was even being mentioned. My reaction was the opposite. I began to pay attention to HTML5.

But Jeff was far from alone. Scott Gilbertson wrote an angry article on Webmonkey:

If you’re thinking that planning how the web will look and work 13 years from now is a little bit ridiculous, you’re not alone.

Even if your 2022 ronc-o-matic web-enabled toaster (It slices! It dices! It browses! It arouses!) does ship with Firefox v22.3, will HTML still be the dominant language of web? Given that no one can really answer that question, does it make sense to propose a standard so far in the future?

(I’m re-reading that article in the current version of Firefox: 95.0.2.)

Brian Veloso wrote on his site:

Two-thousand-twenty-two. That’s 14 years from now. Can any of us think that far? Wouldn’t our robot overlords, whether you welcome them or not, have taken over by then? Will the internet even matter then?

From the comments on Jeff’s post, there’s Corey Dutson:

2022: God knows what the Internet will look like at that point. Will we even have websites?

Dan Rubin, who has indeed successfully moved from web work to photography, wrote:

I certainly don’t intend to be doing “web work” by that time. I’m very curious to see where the web actually is in 14 years, though I can’t imagine that HTML5 will even get that far; it’ll all be obsolete before 2022.

Joshua Works made a prediction that’s worryingly close to reality:

I’ll be surprised if website-as-HTML is still the preferred method for moving around the tons of data we create, especially in the manner that could have been predicted in 2003 or even today. Hell, iPods will be over 20 years old by then and if everything’s not run as an iPhone App, then something went wrong.

Someone with the moniker Grand Caveman wrote:

In 2022 I’ll be 34, and hopefully the internet will be obsolete by then.

Perhaps the most level-headed observation came from Jonny Axelsson:

The world in 2022 will be pretty much like the world in 2009.

The world in 2009 is pretty much like 1996 which was pretty much like the world in 1983 which was pretty much like the world in 1970. Some changes are fairly sudden, others are slow, some are dramatic, others subtle, but as a whole “pretty much the same” covers it.

The Web in 2022 will not be dramatically different from the Web in 2009. It will be less hot and it will be less cool. The Web is a project, and as it succeeds it will fade out of our attention and into the background. We don’t care about things when they work.

Now that’s a sensible perspective!

So who else is looking forward to seeing what the World Wide Web is like in 2036?

I must remember to write a blog post then and link back to this one. I have no intention of trying to predict the future, but I’m willing to bet that hyperlinks will still be around in 14 years.

Speaking of long bets…

Writing the Clearleft newsletter

The Clearleft newsletter goes out every two weeks on a Thursday. You can peruse the archive to see past editions.

I think it’s a really good newsletter, but then again, I’m the one who writes it. It just kind of worked out that way. In theory, anyone at Clearleft could write an edition of the newsletter.

To make that prospect less intimidating, I put together a document for my colleagues describing how I go about creating a new edition of the newsletter. Then I thought it might be interesting for other people outside of Clearleft to get a peek at how the sausage is made.

So here’s what I wrote…

Topics

The description of the newsletter is:

A round-up of handpicked hyperlinks from Clearleft, covering design, technology, and culture.

It usually has three links (maybe four, tops) on a single topic.

The topic can be anything that’s interesting, especially if it’s related to design or technology. Every now and then the topic can be something that incorporates an item that’s specifically Clearleft-related (a case study, an event, a job opening). In general it’s not very salesy at all so people will tolerate the occasional plug.

You can use the “iiiinteresting” Slack channel to find potential topics of interest. I’ve gotten in the habit of popping potential newsletter fodder in there, and then adding related links in a thread.

Tone

Imagine you’re telling a friend about something cool you’ve just discovered. You can sound excited. Don’t worry about this looking unprofessional—it’s better to come across as enthusiastic than too robotic. You can put real feelings on display: anger, disappointment, happiness.

That said, you can also just stick to the facts and describe each link in turn, letting the content speak for itself.

If you’re expressing a feeling or an opinion, use the personal pronoun “I”. Don’t use “we” unless you’re specifically referring to Clearleft.

But most of the time, you won’t be using any pronouns at all:

So-and-so has written an article in such-and-such magazine on this-particular-topic.

You might find it useful to have connecting phrases as you move from link to link:

Speaking of some-specific-thing, this-other-person has a different viewpoint.

or

On the subject of this-particular-topic, so-and-so wrote something about this a while back.

Structure

The format of the newsletter is:

  1. An introductory sentence or short paragraph.
  2. A sentence describing the first link, ending with the title of the item in bold.
  3. A link to the item on its own separate line.
  4. An excerpt from the link, usually a sentence or two, styled as a quote.
  5. Repeat steps 2 to 4 another two times.


Take a look through the archive of previous newsletters to get a feel for it.

Subject line

Currently the newsletter is called dConstruct from Clearleft. The subject line of every edition is in the format:

dConstruct from Clearleft — Title of the edition

(Note that’s an em dash with a space on either side of it separating the name of the newsletter and the title of the edition)

I often try to come up with a pun-based title (often a punny portmanteau) but that’s not necessary. It should be nice and short though: just one or two words.

A Few Notes on A Few Notes on The Culture

When I post a link, I do it for two reasons.

First of all, it’s me pointing at something and saying “Check this out!”

Secondly, it’s a way for me to stash something away that I might want to return to. I tag all my links so when I need to find one again, I just need to think “Now what would past me have tagged it with?” Then I type the appropriate URL: adactio.com/links/tags/whatever

There are some links that I return to again and again.

Back in 2008, I linked to a document called A Few Notes on The Culture. It’s a copy of a post by Iain M Banks to a newsgroup back in 1994.

Alas, that link is dead. Linkrot, innit?

But in 2013 I linked to the same document on a different domain. That link still works even though I believe it was first published around twenty(!) years ago (view source for some pre-CSS markup nostalgia).

Anyway, A Few Notes On The Culture is a fascinating look at the world-building of Iain M Banks’s Culture novels. He talks about the in-world engineering, education, biology, and belief system of his imagined utopia. The part that sticks in my mind is when he talks about economics:

Let me state here a personal conviction that appears, right now, to be profoundly unfashionable; which is that a planned economy can be more productive - and more morally desirable - than one left to market forces.

The market is a good example of evolution in action; the try-everything-and-see-what-works approach. This might provide a perfectly morally satisfactory resource-management system so long as there was absolutely no question of any sentient creature ever being treated purely as one of those resources. The market, for all its (profoundly inelegant) complexities, remains a crude and essentially blind system, and is — without the sort of drastic amendments liable to cripple the economic efficacy which is its greatest claimed asset — intrinsically incapable of distinguishing between simple non-use of matter resulting from processal superfluity and the acute, prolonged and wide-spread suffering of conscious beings.

It is, arguably, in the elevation of this profoundly mechanistic (and in that sense perversely innocent) system to a position above all other moral, philosophical and political values and considerations that humankind displays most convincingly both its present intellectual immaturity and — through grossly pursued selfishness rather than the applied hatred of others — a kind of synthetic evil.

Those three paragraphs might be the most succinct critique of unfettered capitalism I’ve come across. The invisible hand as a paperclip maximiser.

Like I said, it’s a fascinating document. In fact I realised that I should probably store a copy of it for myself.

I have a section of my site called “extras” where I dump miscellaneous stuff. Most of it is unlinked. It’s mostly for my own benefit. That’s where I’ve put my copy of A Few Notes On The Culture.

Here’s a funny thing …for all the times that I’ve revisited the link, I never knew anything about the site is was hosted on—vavatch.co.uk—so this most recent time, I did a bit of clicking around. Clearly it’s the personal website of a sci-fi-loving college student from the early 2000s. But what came as a revelation to me was that the site belonged to …Adrian Hon!

I’m impressed that he kept his old website up even after moving over to the domain mssv.net, founding Six To Start, and writing A History Of The Future In 100 Objects. That’s a great snackable book, by the way. Well worth a read.

Hope

My last long-distance trip before we were all grounded by The Situation was to San Francisco at the end of 2019. I attended Indie Web Camp while I was there, which gave me the opportunity to add a little something to my website: an “on this day” page.

I’m glad I did. While it’s probably of little interest to anyone else, I enjoy scrolling back to see how the same date unfolded over the years.

’Sfunny, when I look back at older journal entries they’re often written out of frustration, usually when something in the dev world is bugging me. But when I look back at all the links I’ve bookmarked the vibe is much more enthusiastic, like I’m excitedly pointing at something and saying “Check this out!” I feel like sentiment analyses of those two sections of my site would yield two different results.

But when I scroll down through my “on this day” page, it also feels like descending deeper into the dark waters of linkrot. For each year back in time, the probability of a link still working decreases until there’s nothing but decay.

Sadly this is nothing new. I’ve been lamenting the state of digital preservation for years now. More recently Jonathan Zittrain penned an article in The Atlantic on the topic:

Too much has been lost already. The glue that holds humanity’s knowledge together is coming undone.

In one sense, linkrot is the price we pay for the web’s particular system of hypertext. We don’t have two-way linking, which means there’s no centralised repository of links which would be prohibitively complex to maintain. So when you want to link to something on the web, you just do it. An a element with an href attribute. That’s it. You don’t need to check with the owner of the resource you’re linking to. You don’t need to check with anyone. You have complete freedom to link to any URL you want to.

But it’s that same simple system that makes the act of linking a gamble. If the URL you’ve linked to goes away, you’ll have no way of knowing.

As I scroll down my “on this day” page, I come across more and more dead links that have been snapped off from the fabric of the web.

If I stop and think about it, it can get quite dispiriting. Why bother making hyperlinks at all? It’s only a matter of time until those links break.

And yet I still keep linking. I still keep pointing to things and saying “Check this out!” even though I know that over a long enough timescale, there’s little chance that the link will hold.

In a sense, every hyperlink on the World Wide Web is little act of hope. Even though I know that when I link to something, it probably won’t last, I still harbour that hope.

If hyperlinks are built on hope, and the web is made of hyperlinks, then in a way, the World Wide Web is quite literally made out of hope.

I like that.

The State of the Web — the links

An Event Apart Spring Summit is happening right now. I opened the show yesterday with a talk called The State Of The Web:

The World Wide Web has come a long way in its three decades of existence. There’s so much we can do now with HTML, CSS, and JavaScript: animation, layout, powerful APIs… we can even make websites that work offline! And yet the web isn’t exactly looking rosy right now. The problems we face aren’t technical in nature. We’re facing a crisis of expectations: we’ve convinced people that the web is slow, buggy, and inaccessible. But it doesn’t have to be this way. There is no fate but what we make. In this perspective-setting talk, we’ll go on a journey to the past, present, and future of web design and development. You’ll laugh, you’ll cry, and by the end, you’ll be ready to make the web better.

I wrote about preparing this talk and you can see the outline on Kinopio. I thought it turned out well, but I never actually know until people see it. So I’m very gratified and relieved that it went down very well indeed. Phew!

Eric and the gang at An Event Apart asked for a round-up of links related to this talk and I was more than happy to oblige. I’ve separated them into some of the same categories that the talk covers.

I know that these look like a completely disconnected grab-bag of concepts—you’d have to see the talk to get the connections. But even without context, these are some rabbit holes you can dive down…

Associative trails

Matt wrote recently about how different writers keep notes:

I’m also reminded of how writers I love and respect maintain their own reservoirs of knowledge, complete with migratory paths down from the mountains.

I have a section of my site called “notes” but the truth is that every single thing I post on here—whether it’s a link, a blog post, or anything else—is really a “note to self.”

When it comes to retrieving information from this online memex of mine, I use tags. I’ve got search forms on my site, but usually I’ll go to the address bar in my browser instead and think “now, what would past me have tagged that with…” as I type adactio.com/tags/... (or, if I want to be more specific, adactio.com/links/tags/... or adactio.com/journal/tags/...).

It’s very satisfying to use my website as a back-up brain like this. I can get stuff out of my head and squirreled away, but still have it available for quick recall when I want it. It’s especially satisfying when I’m talking to someone else and something they say reminds me of something relevant, and I can go “Oh, let me send you this link…” as I retrieve the tagged item in question.

But I don’t think about other people when I’m adding something to my website. My audience is myself.

I know there’s lots of advice out there about considering your audience when you write, but when it comes to my personal site, I’d find that crippling. It would be one more admonishment from the inner critic whispering “no one’s interested in that”, “you have nothing new to add to this topic”, and “you’re not quailified to write about this.” If I’m writing for myself, then it’s easier to have fewer inhibitions. By treating everything as a scrappy note-to-self, I can avoid agonising about quality control …although I still spend far too long trying to come up with titles for posts.

I’ve noticed—and other bloggers have corroborated this—there’s no correlation whatsover between the amount of time you put into something and how much it’s going to resonate with people. You might spend days putting together a thoroughly-researched article only to have it met with tumbleweeds when you finally publish it. Or you might bash something out late at night after a few beers only to find it on the front page of various aggregators the next morning.

If someone else gets some value from a quick blog post that I dash off here, that’s always a pleasant surprise. It’s a bonus. But it’s not my reason for writing. My website is primarily a tool and a library for myself. It just happens to also be public.

I’m pretty sure that nobody but me uses the tags I add to my links and blog posts, and that’s fine with me. It’s very much a folksonomy.

Likewise, there’s a feature I added to my blog posts recently that is probably only of interest to me. Under each blog post, there’s a heading saying “Previously on this day” followed by links to any blog posts published on the same date in previous years. I find it absolutely fascinating to spelunk down those hyperlink potholes, but I’m sure for anyone else it’s about as interesting as a slideshow of holiday photos.

Matt took this further by adding an “on this day” URL to his site. What a great idea! I’ve now done the same here:

adactio.com/archive/onthisday

That URL is almost certainly only of interest to me. And that’s fine.
