100 Days To Offload

The ever-excellent Kev Quirk in 2020 came up with this challenge: write a blog post on each of 100 consecutive days. He called it #100DaysToOffload, in nominal reference to the “100 days of code” challenge. I was reflecting upon this as I reach this, my 36th consecutive day of blogging and my longest ever “daily streak” (itself a spin-off of my attempt at Bloganuary this year), and my 48th post of the year so far.

I guess I’ve always been more of a sprinter/hurdles blogger than a marathon runner.

Might I meet that challenge? Maybe. But it turns out it’s easier than I thought because Kev revised the rules to require only 100 posts in a calendar year (or any other 365-day period, but I’m not going to start thinking about the maths of that).

That’s not only much more-achievable… I’ve probably already achieved it! Let’s knock out some SQL to check how many posts I made each year:

SELECT
  YEAR(wp_posts.post_date_gmt) yyyy,
  COUNT(wp_posts.ID) total
FROM
  wp_posts
WHERE
  wp_posts.post_status='publish'
  AND wp_posts.post_type='post'
GROUP BY yyyy
ORDER BY yyyy
My code’s actually a little more-complicated than this, because of some plot, but this covers the essentials.

A big question in some years is what counts as a post. Kev’s definition is quite liberal and includes basically-everything, but I wonder if mine shouldn’t perhaps be stricter. For example:

  • Should I count checkins, even though they’re not always born as blog posts but often start as logs on geocaching websites? (My gut says yes!)
  • Do reposts and bookmarks contribute, a significant minority of which are presented without any further interpretation by me? (My gut says no!)
  • Does a vlog version of a blog post count separately, or is it a continuation of the same content? (My gut says the volume is too low to matter!)
  • Can a retroactive achievement (i.e. from before the challenge was announced) count? Kev writes “there is no specific start date”, but it seems a little counter to the idea of it specifically being a challenge to claim it when you weren’t attempting the challenge at the time.
  • And so on…
Year Posts Success? Notes
1998 7 ❌ No Some posts are lost from 1998/1999. If they were recovered I might have made 100 posts in 1999, but probably not in 1998 as I only started blogging on 27 September 1998.
1999 66 ❌ No
2000 2 ❌ No
2001 11 ❌ No
2002 5 ❌ No
2003 189 🏆 Yes Achieved 1 September, with a post about an article on The Register about timewasting. Or, if we allow reposts, three days earlier with a repost about Claire's car being claimed by the sea.
2004 374 🏆 Yes An early win on 20 April, with a made-up Chez Geek card. Or if we allow reposts, two days earlier with thoughts on a confusing pro-life (???) website.
2005 381 🏆 Yes In a highly-productive year of blogging, achieved on 7 April with a post about enjoy curry and public information films with friends. If we allow bookmarks (I was highly-active on del.icio.us at the time!), achieved even earlier on 18 February with some links to curious websites.
2006 206 🏆 Yes On 21 July, I shared a personality test (which was actually my effort to repeat an experiment in using Barnum-Forer statements) - I didn't initially give away that I was the author of the "test". Non-pedants will agree I achieved the goal earlier, on 19 June, with my thoughts on a programming language for a hypothetical infinitely-fast computer.
2007 166 🏆 Yes Achieved on 2 July with thoughts on films I'd watched and board games I'd played recently. Or arguably 12 days earlier with Claire's birthday trip to Manchester.
2008 86 ❌ No
2009 79 ❌ No
2010 159
(84 for pedants)
✅ Yes* A heartfelt post about saying goodbye to Aberystwyth as I moved to Oxford on 16 June was my 100th of the year. Pedants might argue that this year shouldn't count, but so long as you're willing to count checkins (and you should) then it would... and my qualifying post would have come only a couple of days later, with a post about the Headington Shark, which I had just moved-in near to.
2011 177 🏆 Yes Reached the goal on 28 October when I wrote about mild successes in my enquiries with the Office of National Statistics about ensuring that information about polyamorous households was accurately recorded. Or if we earlier on 9 June with a visual gag about REM lyrics if you accept all my geocache logs as posts too (and again: you should).
2012 129
(87 for pedants)
✅ Yes* My 100th post of the year came on 28 August when I wrote about launching a bus named after my recently-deceased father. You have to be willing to accept both checkins and reposts as posts to allow this year to count.
2013 138
(59 for pedants)
😓 Probably not I'm not convined this low-blogging year should count: a clear majority of the posts were geocaching logs, and they weren't always even that verbose (consider this candidate for 100th post of 2013, from 1 October).
2014 335
(22 for pedants)
🙁 Not really Another geocache log heavy, conventional blogpost light year that I'm not convinced should count, evem if the obvious candidate for 100th post would be 18 May's cool article about geocaching like Batman!
2015 205
(18 for pedants)
🙁 Not really Still no, for the same reasons as above.
2016 163
(37 for pedants)
🙁 Not really
2017 301
(42 for pedants)
🙁 Not really
2018 547
(87 for pedants)
✅ Yes* I maintain that checkins should count, even when they're PESOS'd from geocaching sites, so long as they don't make up a majority of the qualifying posts in a year. In which case this year should qualify, with the 100th post being my visit to this well-hidden London pub while on my way to a conference.
2019 387
(86 for pedants)
✅ Yes* Similarly this year, when on 15 August I visited a GNSS calibration point in the San Francisco Bay Area... on the way to another conference!
2020 221
(64 for pedants)
✅ Yes* Barely made it this year (ignoring reposts, of which I did lots), with my 21 December article about a little-known (and under-supported) way to inject CSS using HTTP headers, which I later used to make a web page for which View Souce showed nothing.
2021 190
(57 for pedants)
✅ Yes* A cycle to a nearby geocache was the checkin that made the 100th post of this year, on 27 August.
2022 168
(55 for pedants)
✅ Yes* My efforts to check up on one of my own geocaches on 7 September scored the qualifying spot.
2023 164
(86 for pedants)
✅ Yes* My blogging ramped up again this year, and on 24 August I shared a motivational poster with a funny twist, plus a pun at the intersection between my sexuality and my preferred mode of transport.
2024 125
(76 for pedants)
✅ Yes*
Total 4,986 Total count of all the posts.
Doesn't add up? Not all posts feature in one of the years above!

* Pedants might claim this year was not a success for the reasons described above. Make your own mind up.

In any case, I’d argue that I clearly achieved the revised version of the challenge on certainly six, probably fourteen, arguably (depending on how you count posts) as many as nineteen different years since I started blogging in 1998. My least-controversial claims would be:

  1. September 2003, with Timewasting
  2. April 2004, with Chez Geek Card of the Day
  3. April 2005, with Curry with Alec and Suz
  4. July 2006, with Coolest Personality Test I’ve Ever Seen
  5. July 2007, with It’s All Fun and Games
  6. June 2010, with Saying Goodbye
  7. October 2011, with Poly and the Census – Success! (almost)
  8. August 2012, with A Bus Called Peter
  9. June 2018, with Dan Q found GLW6CMKQ 16th Century Pub (Central London) 
  10. August 2019, with Dan Q found GC6KR0H Bay Area Calibration Point #4 – New Technology
  11. December 2020, with The Fourth Way to Inject CSS
  12. August 2021, with Dan Q found GC531M9 Walk by the Firehouse #1
  13. October 2022, with Dan Q performed maintenance for GC9Z37H Friar’s Farm – Woodland Walk
  14. August 2023, with Inclusivity

Given all these unanswered questions, I’m not going to just go ahead and raise a PR against the Hall of Fame! Instead, I’ll leave it to Kev to decide whether I’m (a) eligible to claim a 14-time award, (b) merely eligible for a 4-time award for the years following the challenge starting, or (c) ineligible to claim success until I intentionally post 100 times in a year (in, at current rates, another two months…). Over to you, Kev…

Update: Kev’s agreed that I can claim the most-recent four of them, so I raised a PR.

Lightboxes Without JavaScript

Because I like my blog to be as fast, accessible, and resilient, I try not to use JavaScript for anything I don’t have to1. One example would be my “lightbox”: the way in which images are blown-up if you click on them:

A toasted sandwich containing bacon, lettuce, and tomato.
I used to use this bacon sandwich picture more-often. Let’s dust it off so you can try it (the picture, not the sandwich).

My solution ensures that:

  1. You can click an image and see a full-window popup dialog box containing a larger version of the image.
  2. The larger version of the image isn’t loaded until it’s needed.
  3. You can close the larger version with a close button. You can also use your browser’s back button.
  4. You can click again to download the larger version/use your browser to zoom in further.
  5. You can share/bookmark etc. the URL of a zoomed-in image and the recipient will see the same image (and return to the image, in the right blog post, if they press the close button).
  6. No HTTP round trip is required when opening/closing a lightbox: it’s functionally-instantaneous.2
  7. No JavaScript is used at all.
Visitors can click on images to see a larger version, with a “close” button. No JavaScript needed.

Here’s how it works –

The Markup

<figure id="img3336" aria-describedby="caption-img3336">
  <a href="#lightbox-img3336" role="button">
    <img src="small-image.jpg" alt="Alt text is important." width="640" height="480">
  </a>
  <figcaption id="caption-img3336">
    Here's the caption.
  </figcaption>
</figure>

... (rest of blog post) ...

<dialog id="lightbox-img3336" class="lightbox">
  <a href="large-image.jpg">
    <img src="large-image.jpg" loading="lazy" alt="Alt text is important.">
  </a>
  <a class="close" href="#img3336" title="Close image" role="button">×</a>
</dialog>
The HTML is pretty simple (and I automatically generate it, of course).

For each lightboxed image in a post, a <dialog> for that image is appended to the post. That dialog contains a larger copy of the image (set to loading="lazy" so the browser have to download it until it’s needed), and a “close” button.

The image in the post contains an anchor link to the dialog; the close button in the dialog links back to the image in the post.3 I wrap the lightbox image itself in a link to the full version of the image, which makes it easier for users to zoom in further using their browser’s own tools, if they like.

Even without CSS, this works (albeit with “scrolling” up and down to the larger image). But the clever bit’s yet to come:

The Style

body:has(dialog:target) {
  /* Prevent page scrolling when lightbox open (for browsers that support :has()) */
  position: fixed;
}

a[href^='#lightbox-'] {
  /* Show 'zoom in' cursor over lightboxed images. */
  cursor: zoom-in;
}

.lightbox {
  /* Lightboxes are hidden by-default, but occupy the full screen and top z-index layer when shown. */
  all: unset;
  display: none;
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  z-index: 2;
  background: #333;
}

.lightbox:target {
  /* If the target of the URL points to the lightbox, it becomes visible. */
  display: flex;
}

.lightbox img {
  /* Images fill the lightbox. */
  object-fit: contain;
  height: 100%;
  width: 100%;
}

/* ... extra CSS for styling the close button etc. ... */
Here’s where the magic happens.

Lightboxes are hidden by default (display: none), but configured to fill the window when shown.

They’re shown by the selector .lightbox:target, which is triggered by the id of the <dialog> being referenced by the anchor part of the URL in your address bar!

Summary

It’s neither the most-elegant nor cleanest solution to the problem, but for me it hits a sweet spot between developer experience and user experience. I’m always disappointed when somebody’s “lightbox” requires some heavyweight third-party JavaScript (often loaded from a CDN), because that seems to be the epitome of the “take what the Web gives you for free, throw it away, and reimplement it badly in JavaScript” antipattern.

There’s things I’ve considered adding to my lightbox. Progressively-enhanced JavaScript that adds extra value and/or uses the Popover API where available, perhaps? View Transitions to animate the image “blowing up” to the larger size, while the full-size image loads in the background? Optimistic preloading when hovering over the image4? “Previous/next” image links when lightboxing a gallery? There’s lots of potential to expand it without breaking the core concept here.

I’d also like to take a deeper dive into the accessibility implications of this approach: I think it’s pretty good, but accessibility is a big topic and there’s always more to learn.

In the meantime, why not try out my lightbox by clicking on this picture of my dog (photographed here staring longingly at the bacon sandwich picture above, perhaps).

I hope the idea’s of use to somebody else looking to achieve this kind of thing, too.

Footnotes

1 Where JavaScript is absolutely necessary, I (a) host it on the same domain, for performance and privacy-respecting reasons, and (b) try to provide a functional alternative that doesn’t require JavaScript, ideally seamlessly.

2 In practice, the lightbox images get lazy-loaded, so there can be a short round trip to fetch the image the first time. But after that, it’s instantaneous.

3 The pair – post image and lightbox image – work basically the same way as footnotes, like this one.

4 I already do this with links in general using the excellent instant.page.

Emoji Reactions

I added a stupid feature to my blog.

On some posts, including this one, you can now send an “emoji reaction”. Y’know, for if you’re too lazy to write a comment.

The available reactions vary by post.

That is all.

Making WordPress Fast (The Hard Way)

This isn’t the guide for you

The Internet is full of guides on easily making your WordPress installation run fast. If you’re looking to speed up your WordPress site, you should go read those, not this.

Those guides often boil down to the same old tips:

  1. uninstall unnecessary plugins,
  2. optimise caching (both on the server and, via your headers, on clients/proxies),
  3. resize your images properly and/or ensure WordPress is doing this for you,
  4. use a CDN (and use DNS prefetch hints)1,
  5. tune your PHP installation so it’s got enough memory, keeps a process alive, etc.,
  6. ensure your server is minifying2 and compressing files, and
  7. run it on a faster server/behind a faster connection3
You’ve heard those tips before, right? Today, let’s try something different.

The hard way

This article is for people who aren’t afraid to go tinkering in their WordPress codebase to squeeze a little extra (real world!) performance.

It’s for people whose neverending quest for perfection is already well beyond the point of diminishing returns.

But mostly, it’s for people who want to gawp at me, the freak who actually did this stuff just to make his personal blog a tiny bit nippier without spending an extra penny on hosting.

You shouldn’t use Lighthouse as your only measure of your site’s performance. But it’s still reassuring when you get to see those fireworks!

Don’t start with the hard way. Exhaust all the easy solutions – or at least, make a conscious effort which easy solutions to enact or reject – first. Only if you really want to get into the weeds should you actually try doing the things I propose here. They’re not for most sites, and they’re not the for faint of heart.

Performance is a tradeoff. Every performance improvement costs you something else: time, money, DX, UX, etc. What you choose to trade for performance gains depends on your priority of constituencies, which may differ from mine.4

This is not a recipe book. This won’t tell you what code to change or what commands to run. The right answers for your content will be different than the right answers for mine. Also: you shouldn’t change what you don’t understand! But I hope these tips will help you think about what questions you need to ask to make your site blazing fast.

Okay, let’s get started…

1. Backstab the plugins you can’t live without

If there are plugins you can’t remove because you depend upon their functionality, and those plugins inject content (especially JavaScript) on the front-end… backstab them to undermine that functionality.

For example, if you want Jetpack‘s backup and downtime monitoring features, but you don’t want it injecting random <link rel='stylesheet' id='...-jetpack-css' href='...' media='all' />‘s (an extra stylesheet to download and parse) into your pages: find the add_filter hook it uses and remove_filter it in your theme5.

Screenshot of a code editor showing a typical WordPress theme's header.php, but with the wp_head() line commented out.
Alternatively, entirely remove the wp_head() and manually reimplement the functionality you actually need. Insert your own joke about “Headless WordPress” here.

Better yet, remove wp_head() from your theme entirely6. Now, instead of blocking the hooks you don’t want polluting your <head>, you’re specifically allowing only those you want. You’ll want to take care to get some semi-essential ones like <link rel="canonical" href="...">7.

Now most of your plugins are broken, but in exchange, your theme has reclaimed complete control over what gets sent to the user. You can select what content you actually want delivered, and deliver no more than that. It’s harder work for you, but your site becomes so much lighter.

Animated GIF from The Simpsons. Leonard Nimoy says "Well, my work is done here." Barney says "What do you mean? You didn't do anything?" Nimoy laughs and replies "Didn't I?" before disappearing as if transported away by a Star Trek teleporter.
Your site is faster now. It doesn’t work, but it’s quick about it!

2. Throw away 100% of your render-blocking JavaScript (and as much as you can of the rest)

The single biggest bottleneck to the user viewing a modern WordPress website is the JavaScript that needs to be downloaded, compiled, and executed before the page can be rendered. Most of that’s plugins, but even on a nearly-vanilla installation you might find a copy of jQuery (eww!) and some other files.

In step 1 you threw it all away, which is great… but I’m betting you were depending on some of that to make your site work? Let’s put it back, carefully and selectively, while minimising the impact on load time.

That means scripts should be loaded (a) low-down, and/or (b) marked defer (or, better yet, async), so they don’t block page rendering.

If you haven’t already, you might like to View Source on this page. Count my <script> tags. You’ll probably find just two of them: one external file marked async, and a second block right at the bottom.

Screenshot showing source code of <script> tags on danq.me. There's one <script async> that loads instant.js, and an inline script with three sections: one that adds Web Share API functionality, one that manages VR360 images, and one that loads a service worker.
The only third-party script routinely loaded on danq.me is Instant.Page, which specifically exists to improve perceived performance. It preloads links when you hover over or start-to-touch them.

The inline <script> in my footer.php wraps a single line of PHP: which looks a little like this: <?php echo implode("\n\n", apply_filters( 'danq_footer_js', [] ) ); ?>. For each item in an initially-empty array, it appends to the script tag. When I render anything that requires JavaScript, e.g. for 360° photography, I can just add to that (keyed, to prevent duplicates when viewing an archive page) array. Thus, the relevant script gets added exclusively to the pages where it’s needed, not to the entire site.

The only inline script added to every page loads my service worker, which itself aims to optimise caching as well as providing limited “offline” functionality.

While you’re tweaking your JavaScript anyway, you might like to check that any suitable addEventListeners are set to passive mode. Especially if you’re doing anything with touch or mousewheel events, you can often increase the perceived performance of these interactions by not letting your custom code block the default browser behaviour.

I promise you; most of your blog’s front-end JavaScript is either (a) garbage nobody wants, (b) polyfills for platforms nobody uses, or (c) huge libraries you’ve imported so you can use just one or two functions form them. Trash them.

3. Don’t use a CDN

Wait, what? That’s the opposite of what everybody else recommends. To understand why, you have to think about why people recommend a CDN in the first place. Their reasons are usually threefold:

  1. Proximity
    Claim:
    A CDN delivers content geographically-closer to the user.
    Retort:
    Often true. But in step 4 we’re going to make sure that everything critical comes within the first TCP sliding window anyway, so there’s little benefit, and there’s a cost to that extra DNS lookup and fresh handshake. Edge caching your own content may have value, but for most sites it’ll have a much smaller impact than almost everything else on this list.
  2. Precaching
    Claim:
    A CDN improves the chance resources are precached in the user’s browser.
    Retort: Possibly true, especially with fonts (although see step 6) but less than you’d think with JS libraries because there are so many different versions/hosts of each. Yours may well be the only site in the user’s circuit that uses a particular one!
  3. Power
    Claim: A CDN has more resources than you and so can better-withstand spikes of traffic.
    Retort: Maybe, but they also introduce an additional single-point-of-failure. CDNs aren’t magically immune to downtime nor content-blocking, and if you depend on one you’ve just doubled the number of potential failure points that can make your site instantly useless. Furthermore: in exchange for those resources you’re trading away your users’ privacy and security: if a CDN gets hacked, every site that uses it gets hacked too.

Consider edge-caching your own content only if you think you need it, but ditch jsDeliver, cdnjs, Google Hosted Libraries etc.

Screenshot showing a waterfall representation of downloading and rendering the danq.me homepage. DCL (Dom Content Loaded) occurs at 20.62ms.
Despite having no edge cache and being hosted in a different country to me, I can open a completely fresh browser and reach DOMContentLoaded on the my homepage in ~20ms. You should learn how to read a waterfall performance chart just so you can enjoy how “flat” mine is.

Hell: if you can, ditch all JavaScript served from third-parties and slap a Content-Security-Policy: script-src 'self' header on your domain to dramatically reduce the entire attack surface of your site!8

4. Reduce your HTML and CSS size to <12kb compressed

There’s a magic number you need to know: 12kb. Because of some complicated but fascinating maths (and depending on how your hosting is configured), it can be significantly faster to initially load a web resource of up to 12kb than it is to load one of, say, 15kb. Also, for the same reason, loading a web resource of much less than 12kb might not be significantly faster than loading one only a little less than 12kb.

Exploit this by:

  1. Making your pages as light as possible9, then
  2. Inlining as much essential content as possible (CSS, SVGs, JavaScript etc.) to bring you back up to close-to that magic number again!
$ curl --compressed -so /dev/null -w "%{size_download}\n" https://danq.me/
10416
Note that this is the compressed, over-the-wire size. Last I checked, my homepage weighed-in at about 10.4kb compressed, which includes the entirety of its HTML and CSS, most of its JS, and a couple of its SVG images.

Again, this probably flies in the face of everything you were taught about performance. I’m sure you were told that you should <link> to your stylesheets so that they can be cached across page loads. But it turns out that if you can make your HTML and CSS small enough, the opposite is true and you should inline the stylesheet again: caching styles becomes almost irrelevant if you get all the content in a single round-trip anyway!

For extra credit, consider optimising your homepage’s CSS so it’s even smaller by excluding directives that only apply to non-homepage pages, and vice-versa. Assuming you’re using a preprocessor, this shouldn’t be too hard: at simplest, you can have a homepage.css and main.css, each derived from a set of source files some of which they share (reset/normalisation, typography, colours, whatever) and the rest which is specific only to that part of the site.

Most web pages should fit entirely onto a floppy disk. This one doesn’t, mostly because of all the Simpsons clips, but most should.

Can’t manage to get your HTML and CSS down below the magic number? Then at least ensure that your HTML alone weighs in at <12kb compressed and you’ll still get some of the benefits. If you’ve got the headroom, you can selectively include a <style> block containing only the most-crucial CSS, with a particular focus on any that results in layout shifts (e.g. anything that specifies the height: of otherwise dynamically-sized block elements, or that declares an element position: absolute or position: fixed). These kinds of changes are relatively computationally-expensive because they cause content to re-flow, so provide hints as soon as possible so that the browser can accommodate for them.

5. Make the first load awesome

We don’t really talk about content being “above the fold” like we used to, because the modern Web has such a diverse array of screen sizes and resolutions that doing so doesn’t make much sense.

But if loading your full page is still going to take multiple HTTP requests (scripts, images, fonts, whatever), you should still try to deliver the maximum possible value in the first round-trip. That means:

  • Making sure all your textual content loads immediately! Unless you’re delivering a huge amount of text, there’s absolutely no excuse for lazy-loading text: it’s usually tiny, compresses well, and it’s fast to parse. It’s also the most-important content of most pages. Get it delivered to the browser so it can be rendered rightaway.
  • Lazy-loading images that are “expected” to be below the fold, using the proper HTML mechanism for this (never a JavaScript approach).
  • Reserving space for blocks by sizing images appropriately, e.g. using <img width="..." height="..." ...> or having them load as a background with background-size: cover or contain in a block sized with CSS delivered in the initial payload. This reduces layout shift, which mitigates the need for computationally-expensive content reflows.
  • If possible (see point 4), move vector images that support basic site functionality, like logos, inline. This might also apply to icons, if they’re “as important” as text content.
  • Marking everything up with standard semantic HTML. There’s a trend for component-driven design to go much too far, resulting in JavaScript components being used in place of standard elements like links, buttons, and images, resulting in highly-fragile websites: when those scripts fail (or are very slow to load), the page becomes unusable.
Screenshot of danq.me's homepage with all external resources and all CSS disabled. It's plain-text, but it's still entirely useable.
If you want to be sure you’re prioritising your content first and foremost, try disabling all CSS, JavaScript, and external resources (or just access your site in a browser that ignores those things, like Lynx), and check that it’s still usable. As a bonus, this helps you check for several accessibility issues.

6. Reduce your dependence on downloaded fonts

Fonts are lovely and can be an important part of your brand identity, but they can also add a lot of weight to your web pages.

If you’re ready and able to drop your webfonts and appreciate the beauty and flexibility of a system font stack (I get it: I’m not there quite yet!), you can at least make smarter use of your fonts:

  • Every modern browser supports WOFF2, so you can ditch those chunky old formats you’re clinging onto.
  • If you’re only using the Latin alphabet, minify your fonts further by dropping the characters you don’t need: tools like Google Webfonts Helper can help with this, as well as making it easier to selfhost fonts from the most-popular library (is a smart idea for the reasons described under point 3, above!). There are tools available to further minify fonts if e.g. you only need the capital letters for your title font or something.
      • Browsers are pretty clever and will work-around it if you make a mistake. Didn’t include an emoji or some obscure mathematical symbol, and then accidentally used them in a post? Browsers will switch to a system font that can fill in the gap, for you.
  • Make the most-liberal use of the font-display: CSS directive that you can tolerate!
    • Don’t use font-display: block, which is functionally the default in most browsers, unless you absolutely have to.
    • font-display: fallback is good if you’re too cowardly/think your font is too important for you to try font-display: optional.
    • font-display: optional is an excellent choice for body text: if the browser thinks it’s worthwhile to download the font (it might choose not to if the operating system indicates that it’s using a metered or low-bandwidth connection, for example), it’ll try to download it, but it won’t let doing so slow things down too much and it’ll fall-back to whatever backup (system) font you specify.
    • font-display: swap is also worth considering: this will render any text immediately, even if the right font hasn’t downloaded yet, with no blocking time whatsoever, and then swap it for the right font when it appears. It’s probably better for headings, because large paragraphs of text can be a little disorienting if they change font while a user is looking at them!
If writing is for nerds, then typography must be doubly-so. But you’ve read this far, so I’m confident that you qualify…

7. Cache pre-compressed static files

It’s possible that by this point you’re saying “if I had to do this much work, I might as well just use a static site generator”. Well good news: that’s what you’re about to do!

Obviously you should make sure all your regular caching improvements (appropriate HTTP headers for caching, a service worker that further improves on that logic based on your content’s update schedule, etc.) first. Again: everything in this guide presupposes that you’ve already done the things that normal people do.

By aggressively caching pre-compressed copies of all your pages, you’re effectively getting the best of both worlds: a website that, for anonymous visitors, is served directly from .html.gz files on a hard disk or even straight from RAM in memcached10, but which still maintains all the necessary server-side interactivity to allow it to be used as a conventional Web-based CMS (including accepting comments if that’s your jam).

WP Super Cache can do the heavy lifting for you for a filesystem-based solution so long as you put it into “Expert” mode and amending your webserver configuration. I’m using Nginx, so I needed a try_files directive like this:

location / {
  try_files /wp-content/cache/supercache/$http_host/$wp_super_cache_path/index-https.html $uri $uri/ /index.php?$args;
}

8. Optimise image formats

I’m sure your favourite performance testing tool has already complained at you about your failure to use the best formats possible when serving images to your users. But how can you fix it?

There are some great plugins for improving your images automatically and/or in bulk – I use EWWW Image Optimizer – but to really make the most of them you’ll want to reconfigure your webserver to detect clients that Accept: image/webp and attempt to dynamically serve them .webp variants, for example. Or if you’re ready to give up on legacy formats and replace all your .pngs with .webps, that’s probably fine too!

Image containing the text
The image you see at https://danq.me/_q23u/2023/11/dynamic.png is probably an image/webp. But if your browser doesn’t support WebP, you’ll get an image/png instead!

Assuming you’ve got curl and Imagemagick‘s identify, you can see this in action:

  • curl -s https://danq.me/_q23u/2023/11/dynamic.png -H "Accept: image/webp" | identify -
    (Will give you a WebP image)
  • curl -s https://danq.me/_q23u/2023/11/dynamic.png -H "Accept: image/png" | identify -
    (Will give you a PNG image, even though the URL is the same)

9. Simplify, simplify, simplify

The single biggest impact you can have upon the performance of your WordPress pages is to make them less complex.

I’m not necessarily saying that everybody should follow in my lead and co-publish their WordPress sites on the Gemini protocol. But you’ve got to admit: the simplicity of the Gemini protocol and the associated Gemtext format makes both lightning fast.

Screenshot showing this blog post as viewed via Gemini, in the Lagrange browser.
You don’t have to go as light as Gemtext – like this page on Gemini does – to see benefits.

Writing my templates and posts so that they’re compatible with CapsulePress helps keep my code necessarily-simple. You don’t have to do that, though, but you should be asking yourself:

  • Does my DOM need to cascade so deeply? Could I achieve the same with less?
  • Am I pre-emptively creating content, e.g. adding a hidden <dialog> directly to the markup in the anticipation that it might be triggered later using JavaScript, rather than having that JavaScript run document.createElement the element after the page becomes readable?
  • Have I created unnecessarily-long chains of CSS selectors11 when what I really want is a simple class name, or perhaps even a semantic element name?

10. Add a Service Worker

A service worker isn’t magic. In particular, it can’t help you with those new visitors hitting your site for the first time12.

A service worker lets you do smart things on behalf of the user’s network connection, so that by the time they ask for a resource, you already fetched it for them.

But a suitable service worker can do a few things that can help with performance. In particular, you might consider:

  • Precaching assets that you anticipate they’re likely to need (e.g. if you use different stylesheets for the homepage and other pages, you can preload both so no matter where a user lands they’ve already got the CSS they’ll need for the entire site).
  • Preloading popular pages like the homepage and recent articles, allowing them to load quickly.
  • Caching a fallback pages – and other resources as-they’re-accessed – to support a full experience for users even if they (or your site!) disconnect from the Internet (or even embedding “save for offline” functionality!).

Chapters 7 and 8 of Going Offline by Jeremy Keith are especially good for explaining how this can be achieved, and it’s all much easier than everything else I just described.

Anything else?

Did I miss anything? If you’ve got a tip about ramping up WordPress performance that isn’t one of the “typical seven” – probably because it’s too hard to be worthwhile for most people – I’d love to hear it!

Footnotes

1 You’ll sometimes see guides that suggest that using a CDN is to be recommended specifically because it splits your assets among multiple domains/subdomains, which mitigates browsers’ limitation on the number of files they can download simultaneously. This is terrible advice, because such limitations essentially don’t exist any more, but DNS lookups and TLS handshakes still have a bandwidth and computational cost. There are good things about CDNs, sometimes, but this has not been one of them for some time now.

2 I’m not sure why guides keep stressing the importance of minifying code, because by the time you’re compressing them too it’s almost pointless. I guess it’s helpful if your compression fails?

3 “Use a faster server” is a “just throw money/the environment at it” solution. I’d like to think we can do better.

4 For my personal blog, I choose to prioritise user experience, privacy, accessibility, resilience, and standards compliance above almost everything else.

5 If you prefer to keep your backstab code separate, you can put it in a custom plugin, but you might find that you have to name it something late in the alphabet – I’ve previously used names like zzz-danq-anti-plugin-hacks – to ensure that they load after the plugins whose functionality you intend to unhook: broadly-speaking, WordPress loads plugins in alphabetical order.

6 I’ve assumed you’re using a classic, not block, theme. If you’re using a block theme, you get a whole different set of performance challenges to think about. Don’t get me wrong: I love block themes and think they’re a great way to put more people in control of their site’s design! But if you’re at the point where you’re comfortable digging this deep into your site’s PHP code, you probably don’t need that feature anyway, right?

7 WordPress is really good at serving functionally-duplicate content, so search engines appreciate it if you declare a proper canonical URL.

8 Before you choose to block all third-party JavaScript, you might have to whitelist Google Analytics if you’re the kind of person who doesn’t mind selling their visitor data to the world’s biggest harvester of personal information in exchange for some pretty graphs. I’m not that kind of person.

9 You were looking to join me in 512kb club anyway, right?

10 I’ve experimented with mounting a ramdisk and storing the WP Super Cache directory there, but it didn’t make a huge difference, probably because my files are so small that the parse/render time on the browser side dominates the total cascade, and they’re already being served from an SSD. I imagine in my case memcached would provide similarly-small benefits.

11 I really love the power of CSS preprocessors like Sass, but they do make it deceptively easy to create many more – and longer – selectors than you intended in your final compiled stylesheet.

12 Tools like Lighthouse usually simulate first-time visitors, which can be a little unfair to sites with great performance for established visitors. But everybody is a first-time visitor at least once (and probably more times, as caches expire or are cleared), so they’re still a metric you should consider.

CapsulePress – Gemini / Spartan / Gopher to WordPress bridge

For a while now, this site has been partially mirrored via the Gemini1 and Gopher protocols.2 Earlier this year I presented hacky versions of the tools I’d used to acieve this (and made people feel nostalgic).

Now I’ve added support for Spartan3 too and, seeing as the implementations shared functionality, I’ve combined all three – Gemini, Spartan, and Gopher – into a single package: CapsulePress.

Diagram illustrating the behaviour of CapsulePress: a WordPress installation provides content, and CapsulePress makes that content available via gemini://, spartan://, and gopher:// URLs.

CapsulePress is a Gemini/Spartan/Gopher to WordPress bridge. It lets you use WordPress as a CMS for any or all of those three non-Web protocols in addition to the Web.

For example, that means that this post is available on all of:

Composite screenshot showing this blog post in, from top-left to bottom-right: (1) Firefox, via HTTPS, (2) Lagrange, via Gemini, (3) Lagrange, via Spartan, and (4) Lynx, via Gopher.

It’s also possible to write posts that selectively appear via different media: if I want to put something exclusively on my gemlog, I can, by assigning metadata that tells WordPress to suppress a post but still expose it to CapsulePress. Neat!

90s-style web banners in the style of Netscape ads, saying "Gemini now!", "Spartan now!", and "Gopher now!". Beneath then a wider banner ad promotes CapsulePress v0.1.
Using Gemini and friends in the 2020s make me feel like the dream of the Internet of the nineties and early-naughties is still alive. But with fewer banner ads.

I’ve open-sourced the whole thing under a super-permissive license, so if you want your own WordPress blog to “feed” your Gemlog… now you can. With a few caveats:

  • It’s hard to use. While not as hacky as the disparate piles of code it replaced, it’s still not the cleanest. To modify it you’ll need a basic comprehension of all three protocols, plus Ruby, SQL, and sysadmin skills.
  • It’s super opinionated. It’s very much geared towards my use case. It’s improved by the use of templates. but it’s still probably only suitable for this site for the time being, until you make changes.
  • It’s very-much unfinished. I’ve got a growing to-do list, which should be a good clue that it’s Not Finished. Maybe it never will but. But there’ll be changes yet to come.

Whether or not your WordPress blog makes the jump to Geminispace4, I hope you’ll came take a look at mine at one of the URLs linked above, and then continue to explore.

If you’re nostalgic for the interpersonal Internet – or just the idea of it, if you’re too young to remember it… you’ll find it there. (That Internet never actually went away, but it’s harder to find on today’s big Web than it is on lighter protocols.)

Stopping WordPress Emoji ‘Images’ in Feeds

After sharing that Octopuns has started posting again after a 9½-year hiatus earlier today, I noticed something odd: where I’d written “I ❤️ FreshRSS“, the heart emoji was huge when viewed in my favourite feed reader.

Screenshot from a web-based RSS reader application, showing recent repost "Groundhog Day". The final line contains a link with the text "I ❤️ FreshRSS", but the red heart emoji seems to be enormous compared to the next adjacent to it.
Why yes, I do subscribe to my own RSS feed. What of it?

It turns out that by default, WordPress replaces emoji in its feeds (and when sending email) with images of those emoji, using the Tweemoji set, and with the alt-text set to the original emoji. These images are hosted at https://s.w.org/images/core/emoji/…-based URLs.

For example, this heart was served with the following HTML code (the number 2764 refers to the codepoint of the emoji):

<img src="https://s.w.org/images/core/emoji/14.0.0/72x72/2764.png"
     alt="❤"
   class="wp-smiley"
   style="height: 1em; max-height: 1em;"
/>

I can see why this functionality was added: what if the feed reader didn’t support Unicode or didn’t have a font capable of showing the appropriate emoji?

But I can also see reasons why it might not be desirable to everybody. For example:

  1. Downloading an image will always be slower than rendering an emoji.
  2. The code to include an image is always more-verbose than simply including an emoji.
  3. As seen above: a feed reader which imposes a minimum size on embedded images might well render one “wrong”.
  4. It’s marginally more-verbose for screen reader users to say “Image: heart emoji” than just “heart emoji”, I imagine.
  5. Serving an third-party image when a feed item is viewed has potential privacy implications that I try hard to avoid.
  6. Replacing emoji with images is probably unnecessary for modern feed readers anyway.

I opted to remove this functionality. I briefly considered overriding the emoji_url filter (which could be used to selfhost the emoji set) but I discovered that I could just un-hook the filters that were being added in the first place.

Here’s what I added to my theme’s functions.php:

remove_filter( 'the_content_feed', 'wp_staticize_emoji' );
remove_filter( 'comment_text_rss', 'wp_staticize_emoji' );

That’s all there is to it. Now, my feed reader shows my system’s emoji instead of a huge image:

Screenshot from a web-based RSS reader application, showing recent repost "Groundhog Day". The final line contains a link with the text "I ❤️ FreshRSS" shown correctly, with a red heart emoji at the appropriate font size.

I’m always grateful to discover that a piece of WordPress functionality, whether core or in an extension, makes proper use of hooks so that its functionality can be changed, extended, or disabled. One of the single best things about the WordPress open-source ecosystem is that you almost never have to edit somebody else’s code (and remember to re-edit it every time you install an update).

Want to hear about other ways I’ve improved WordPress’s feeds?

Better WordPress RSS Feeds

I’ve made a handful of tweaks to my RSS feed which I feel improves upon WordPress’s default implementation, at least in my use-case.1 In case any of these improvements help you, too, here’s a list of them:

Post Kinds in Titles

Since 2020, I’ve decorated post titles by prefixing them with the “kind” of post they are (courtesy of the Post Kinds plugin). I’ve already written about how I do it, if you’re interested.

Screenshot showing a Weekly Digest email from DanQ.me, with two Notes and a Repost clearly-identified.
Identifying post kinds is particularly useful for people who subscribe by email (the emails are generated off the RSS feed either daily or weekly: subscriber’s choice), who might want to see articles and videos but not care about for example checkins and reposts.

RSS Only posts

A minority of my posts are – initially, at least – publicised only via my RSS feed (and places that are directly fed by it, like email subscribers). I use a tag to identify posts to be hidden in this way. I’ve written about my implementation before, but I’ve since made a couple of additional improvements:

  1. Suppressing the tag from tag clouds, to make it harder to accidentally discover these posts by tag-surfing,
  2. Tweaking the title of such posts when they appear in feeds (using the same technique as above), so that readers know when they’re seeing “exclusive” content, and
  3. Setting a X-Robots-Tag: noindex, nofollow HTTP header when viewing such tag or a post, to discourage search engines (code for this not shown below because it’s so very specific to my theme that it’s probably no use to anybody else!).
// 1. Suppress the "rss club" tag from tag clouds/the full tag list
function rss_club_suppress_tags_from_display( string $tag_list, string $before, string $sep, string $after, int $post_id ): string {
  foreach(['rss-club'] as $tag_to_suppress){
    $regex = sprintf( '/<li>[^<]*?<a [^>]*?href="[^"]*?\/%s\/"[^>]*?>.*?<\/a>[^<]*?<\/li>/', $tag_to_suppress );
    $tag_list = preg_replace( $regex, '', $tag_list );
  }
  return $tag_list;
}
add_filter( 'the_tags', 'rss_club_suppress_tags_from_display', 10, 5 );

// 2. In feeds, tweak title if it's an RSS exclusive
function rss_club_add_rss_only_to_rss_post_title( $title ){
  $post_tag_slugs = array_map(function($tag){ return $tag->slug; }, wp_get_post_tags( get_the_ID() ));
  if ( ! in_array( 'rss-club', $post_tag_slugs ) ) return $title; // if we don't have an rss-club tag, drop out here
  return trim( "{$title} [RSS Exclusive!]" );
  return $title;
}
add_filter( 'the_title_rss', 'rss_club_add_rss_only_to_rss_post_title', 6 );

Adding a stylesheet

Adding a stylesheet to your feeds can make them much friendlier to beginner users (which helps drive adoption) without making them much less-convenient for people who know how to use feeds already. Darek Kay and Terence Eden both wrote great articles about this just earlier this year, but I think my implementation goes a step further.

Screenshot of DanQ.me's RSS feed as viewed in Firefox, showing a "Q" logo and three recent posts.
I started with Matt Webb‘s pretty-feed-v3.xsl by Matt Webb (as popularised by AboutFeeds.com) and built from there.

In addition to adding some “Q” branding, I made tweaks to make it work seamlessly with both my RSS and Atom feeds by using two <xsl:for-each> blocks and exploiting the fact that the two standards don’t overlap in their root namespaces. Here’s my full XSLT; you need to override your feed template as Terence describes to use it, but mine can be applied to both RSS and Atom.2

I’ve still got more I’d like to do with this, for example to take advantage of the thumbnail images I attach to posts. On which note…

Thumbnail images

When I first started offering email subscription options I used Mailchimp’s RSS-to-email service, which was… okay, but not great, and I didn’t like the privacy implications that came along with it. Mailchimp support adding thumbnails to your email template from your feed, but WordPress themes don’t by-default provide the appropriate metadata to allow them to do that. So I installed Jordy Meow‘s RSS Featured Image plugin which did it for me.

</item>
Media attachments for RSS feeds are perhaps most-popular for podcasts, but they’re also great for post thumbnail images.

During my little redesign earlier this year I decided to go two steps further: (1) ditching the plugin and implementing the functionality directly into my theme (it’s really not very much code!), and (2) adding not only a <media:content medium="image" url="..." /> element but also a <media:description> providing the default alt-text for that image. I don’t know if any feed readers (correctly) handle this accessibility-improving feature, but my stylesheet above will, some day!

Here’s how that’s done:

function rss_insert_namespace_for_featured_image() {
  echo "xmlns:media=\"http://search.yahoo.com/mrss/\"\n";
}

function rss_insert_featured_image( $comments ) {
  global $post;
  $image_id = get_post_thumbnail_id( $post->ID );
  if( ! $image_id ) return;
  $image = get_the_post_thumbnail_url( $post->ID, 'large' );
  $image_url = esc_url( $image );
  $image_alt = esc_html( get_post_meta( $image_id, '_wp_attachment_image_alt', true ) );
  $image_title = esc_html( get_the_title( $image_id ) );
  $image_description = empty( $image_alt ) ? $image_title : $image_alt;
  if ( !empty( $image ) ) {
    echo <<<EOF
      <media:content url="{$image_url}" medium="image" />
      <media:description>{$image_description}</media:description>
    EOF;
  }
}

add_action( 'rss2_ns', 'rss_insert_namespace_for_featured_image' );
add_action( 'rss2_item', 'rss_insert_featured_image' );

So there we have it: a little digital gardening, and four improvements to WordPress’s default feeds.

RSS may not be as hip as it once was, but little improvements can help new users find their way into this (enlightened?) way to consume the Web.

If you’re using RSS to follow my blog, great! If it’s not for you, perhaps pick your favourite alternative way to get updates, from options including email, Telegram, the Fediverse (e.g. Mastodon), and more…

Update 4 September 2023: More-recently, I’ve improved WordPress RSS feeds by preventing them from automatically converting emoji into images.

Footnotes

1 The changes apply to the Atom feed too, for anybody of such an inclination. Just assume that if I say RSS I’m including Atom, okay?

2 The experience of writing this transformation/stylesheet also gave me yet another opportunity to remember how much I hate working with XSLTs. This time around, in addition to the normal namespace issues and headscratching syntax, I had to deal with the fact that I initially tried to use a feature from XSLT version 2.0 (a 22-year-old version) only to discover that all major web browsers still only support version 1.0 (specified last millenium)!

Short-Term Blogging

There’s a perception that a blog is a long-lived, ongoing thing. That it lives with and alongside its author.1

But that doesn’t have to be true, and I think a lot of people could benefit from “short-term” blogging. Consider:

  • Photoblogging your holiday, rather than posting snaps to social media
    You gain the ability to add context, crosslinking, and have permanent addresses (rather than losing eveything to the depths of a feed). You can crosspost/syndicate to your favourite socials if that’s your poison..

Photoblog your holiday and I might follow it, and I’ll do so at my convenience. Put your snaps on Facebook and I almost certainly won’t bother. Photo courtesy ArtHouse Studio.
  • Blogging your studies, rather than keeping your notes to yourself
    Writing what you learn helps you remember it; writing what you learn in a public space helps others learn too and makes it easy to search for your discoveries later.2
  • Recording your roleplaying, rather than just summarising each session to your fellow players
    My D&D group does this at levellers.blog! That site won’t continue to be updated forever – the party will someday retire or, more-likely, come to a glorious but horrific end – but it’ll always live on as a reminder of what we achieved.

One of my favourite examples of such a blog was 52 Reflect3 (now integrated into its successor The Improbable Blog). For 52 consecutive weeks my partner‘s brother Robin blogged about adventures that took him out of his home in London and it was amazing. The project’s finished, but a blog was absolutely the right medium for it because now it’s got a “forever home” on the Web (imagine if he’d posted instead to Twitter, only for that platform to turn into a flaming turd).

I don’t often shill for my employer, but I genuinely believe that the free tier on WordPress.com is an excellent way to give a forever home to your short-term blog4. Did you know that you can type new.blog (or blog.new; both work!) into your browser to start one?

What are you going to write about?

1 This blog is, of course, an example of a long-term blog. It’s been going in some form or another for over half my life, and I don’t see that changing. But it’s not the only kind of blog.

2 Personally, I really love the serendipity of asking a web search engine for the solution to a problem and finding a result that turns out to be something that I myself wrote, long ago!

3 My previous posts about 52 Reflect: Challenge Robin, Twatt, Brixton to Brighton by Boris Bike, Ending on a High (and associated photo/note)

4 One of my favourite features of WordPress.com is the fact that it’s built atop the world’s most-popular blogging software and you can export all your data at any time, so there’s absolutely no lock-in: if you want to migrate to a competitor or even host your own blog, it’s really easy to do so!

WCEU23 – Day 2

My second day of the main conference part of WordCamp Europe 2023 was hampered slightly by a late start on my part.

Dan, sweating, with an actively-used dancefloor in the background.
I can’t say for certain why I woke up mildly hungover and with sore knees, but I make an educated guess that it might be related to the Pride party I found myself at last night.

Still, I managed to get to all the things I’d earmarked for my attention, including:


Gutenberg collaborative editing experience

I’m sure I can’t be the only person who’s been asked “why can’t the (or ‘shouldn’t the’) WordPress post editor let multiple people edit post at the same time”. Often, people will compare it to e.g. Google Docs.

A man in a blue shirt stands on a large stage.
I can’t begin to speculate how often people must ask this supposedly-trivial question of Dawid Urbański, possibly the world’s expert on this very question.

Dawid summarised the challenging issues in any effort to implement this much-desired feature. Some of them are examples of those unsolved problems that keep rearing their heads in computer science, like the two generals’ problem, but even the solvable problems are difficult: How does one handle asynchronous (non-idempotent) commutative operations? How is the order of disparate actions determined? Which node is the source of truth? If a server is used, where is that server (with a nod to quite how awful the experience of implementing a Websockets server in PHP can be…)? And so on…

Slide showing a timeline in which two participants A and B send an update to one another, but neither can be sure whose update was made first.
Slides showing simplified timelines of parties communicating with one another in ambigous ways

I really appreciated Dawid’s reference to the various bits of academic literature that’s appeared over the last four decades (!) about how these problems might be solved. It’s a strong reminder that these things we take for granted in live-updating multi-user web applications are not trivial and every question you can answer raises more questions.

There’s some great early proof-of-concepts, so we’re “getting there”, and it’s an exciting time. Personally, I love the idea of the benefits this could provide for offline editing (perhaps just because I’m still a huge fan of a well-made PWA!).


The future of work is open

James Giroux’s goal: that we all become more curious about and more invested in our team’s experiences, from a humanistic standpoint. His experience of companies with organic growth of software companies is very, very familiar: you make a thing and give it away, then you need more people, then you’ve somehow got a company and it’s all because you just had an idea once. Sounds like Three Rings!

A man in a white t-shirt and dark jacket stands on a stage in front of a screen; the bottom line of the words on the screen can be seen to read "Work is Open".
Financial success is not team success, as Twitter shows, with their current unsustainable and unhappy developer culture, James reminds us.

James was particularly keen to share with us the results of his Team Experience Index research, and I agree that some of the result are especially exciting, in particularly the willingness of underrepresented groups, especially women, to enagage with the survey: this provides hugely valuable data about the health of teams working in the WordPress space.

A slide showing demographic details: 28% say that they represent a historically underrepresented group, 55% are in North America, 67% provided a gender that was not "male".
The statistician in me immediately wanted to know how the non-response rate to these (optional) questions varied relative to one another (if they’re very different, putting these pie charts alongside one another could be disingenuous!), but I’m tentatively excited by the diversity represented anyway.

“We have this project that we work with and contribute to, that we love,” says James, in an attempt to explain the highly-positive feedback that his survey respondents gave when asked questions about the authenticity of their purpose and satisfaction in their role.

A man on a stage stands in front of a slide listing strengths and opportunities resulting from the survey.
Again, my inner statistician wants to chirp up about the lack of a control group. The data from the survey may well help companies working within the WordPress ecosystem to identify things we’re doing well and opportunities for growth, but it’d also be cool to compare these metrics to those in companies outside of the WordPress world!

So, what do we do with these findings? How do WordPress-ey companies improve? James recommends that we:

  • Get better are showing what recognition, celebration, and career growth looks like,
  • Improve support and training for team leaders to provide them with the tools to succeed and inspire, and
  • Bridge the gap between leadership and team members with transparent, open dialogue.

Good tips, there.


The Big Photo

A WordCamp tradition is to try to squeeze every willing participant into a photo. Clearly with the size that these events are, nowadays, this requires some wrangling (and, in this case, the photographers standing atop the roof of a nearby building to get everybody into frame).

An enormous crowd shuffles tightly into a courtyard. A trio of blue-shirted photographers stands atop a building opposite them.
Like herding cats, trying to get several hundred people to line up where you want them for a photograph is an exercise in patience.

I’ll have to keep an eye out for the final picture and see if I can find myself in it.


What is new in CSS?

I always find that learning about bleeding edge CSS techniques makes me feel excited and optimistic, perhaps because CSS lends itself so well towards a progressive enhancement approach to development: often, you can start using a new technique today and it’ll only benefit, say, people using a beta version of a particular browser (and perhaps only if they opt-in to the applicable feature flag). But if you’ve designed your site right then the lack of this feature won’t impact anybody else, and eventually the feature will (hopefully) trickle-down into almost everybody’s Web experience.

Anyway, that’s what Fellyph Cintra says too, but he adds that possibly we’ve still not grown out of thinking that browsers take a long time between versions. 5 years passed between the release of Internet Explorer 6 and Internet Explorer 7, for example! But nowadays most browsers are evergreen with releases each month! (Assuming we quietly ignore that Apple don’t sent new versions of Safari to old verisons of MacOS, continuing to exacerbate a problem that we used to see with Internet Explorer on Windows, ahem.)

A man on a stage with his arm out in greeting to the crowd in front of him.
Fellyph told us about how he introduced <dialog> to his team and they responded with skepticism that they’d be able to use it within the next 5 years. But in fact it’s already stable in every major browser.

An important new development may come from Baseline, a project to establish a metric of what you can reliably use on the Web today. So a bit like Can I Use, I guess, but taken from the opposite direction: starting from the browsers and listing the features, rather than the other way around.

Anyway, Fellyph went on to share some exciting new ideas that we should be using, like:

  • object-fit and object-position, which can make the contents of any container “act like” a background
  • aspect-ratio, which I’m already using and I love, but I enjoyed how Fellyph suggested combining the two to crop images to a fluid container on the client side
  • scroll-behavior: smooth, which I’ve used before; it’s pretty good
  • clamp, which I use… but I’m still not sure I fully grok it: I always have to load some documentation with examples when I use it
  • @container queries, which can apply e.g. (max-width: ...) rules to things other than the viewport, which I’ve not found a need for yet but I can see the value of it
  • @layers, which grant an additional level of importance in the cascade: for example, you might load a framework into a layer (with @import url(...) layer(framework)) which is defined as a lower-priority than your override layer, meaning you won’t have to start slapping !important all over the shop
  • @media (400px <= width <= 600px)-style media queries, which are much easier to understand than min-width: if you’re used to thinking in a more-procedural programming language (I assume they work in container queries too!)
Fellyph Cintra stands in front of a large screen showing a slide that introduces himself to his audience: "Front-end Lead at Digitale Methode & Google Developer Expert @fellyph"

It’s also worth remembering:

  • @supports, which is badass and I love and use it already (it was especially useful as display: grid began to roll out and I wanted to start using it but needed to use a fallback method for browsers that didn’t support it yet
  • :has(), which I’ve long thought is game-changing: styling something based on what it contains is magical; not really suitable for mainstream use yet without Firefox support, though (it’s still behind a feature flag)! Fellyph sold me on the benefit of :not(:has(...)), though!
  • Nesting, which again doesn’t have Firefox support yet but provides SCSS-like nesting in CSS, which is awesome
  • Scroll-driven animations, which can e.g. do parallax effects without JavaScript (right now it’s Canary only, mind…), using e.g. animation-timeline: and animation-range: to specify that it’s the scroll position within the document that provides the timeline for the animation

And keeping an eye on upcoming things like text-balanced (which I’m already excited by), popover, selectmenu, view transitions (which I’ve been experimenting with because they’re cool), and scoped style.

Fellyph was at least as inspiring as I’d hoped.


Stop blocking my thread

For my second workshop, I joined Google’s Adam Silverstein to watch him dissect a few participants’ websites performance using Core Web Vitals as a metric. I think I already know the basics of Core Web Vitals, but when it comes to improving my score (especially on work-related sites with unpleasant reliance on heavyweight frameworks like React, in my experience).

A man stands at a podium.
In an early joke, Adam pointed out that you can reduce JavaScript thread blocking by removing JavaScript from your site. A lot of people laughed, but frankly I think it’s a great idea.

We talked a lot about render blocking (thanks to JS and CSS in the <head>), thread blocking (by scripts, especially those reacting to user input), TTFB (relating to actual network and server performance, or at least server-side processing), TBT (the time between FCP and TTI), and the upcoming change to measure INP rather than FID. That’s a lot of acronyms.

The short of it is that there are three pillars to Core Web Vitals: loading (how long until the page renders), interactivity (how long until the page responds to user interaction), and stability (how long it takes for the page to cease layout shifts as a result of post-load scripts and stylesheets). I was pleased that Adam acknowledged the major limitation of lab testing resulting from developers often using superior hardware and Internet connections to typical users, and how if you’re serious about performance metrics you’ll want to collect RUM data.

Adam explaining Render-Blocking CSS.
The fastest way to improve rendering performance is to put fewer obstacles in the way of rendering.

I came away with a few personalised tips, but they’re not much use for your site: I paid attention to the things that’ll be helpful for the sites I look after. But I’ll be taking note of his test pages so I can play with some of the tools he demonstrated later on.


Variations on a theme: 20 years of WordPress

I couldn’t liveblog this because I spent too much of the session applauding. A few highlights from memory:

  • Phase 2 (of 4) of Gutenberg is basically complete, which is cool. Some back-and-forth about the importance of phase 4 (bringing better multilingual support to WordPress) and how it feels like it’s a long way away.
  • Lots of plugging for Five for the Future, which I can get behind.
  • In the same vein as his 2016 statement that WordPress developers should “learn JavaScript deeply”, Matt leant somewhat into the idea that from today they should “watch AI carefully”; I’m not 100% convinced, but it’s not been stopping me from getting involved with a diversity of AI experiments (including some WordPress-related ones) anyway.
  • Musings about our community being a major part of why WordPress succeeded (and continues to thrive) unlike some other open source projects of its era. I agree that’s a factor, but I suspect that being in the right place at the right time was also important. Perhaps more on that another time.
  • Announcement of the next WordCamp Europe location.

Here’s looking forward to WordCamp Europe 2024 in Turin!

WCEU23 – Day 1

The first “full” day of WordCamp Europe 2023 (which kicked-off at Contributor Day) was busy and intense, but I loved it.

This post is basically a live-blog of everything I got up to, and it’s mostly for my own benefit/notetaking. If you don’t read it, nobody will blame you.

Seen from behind, a very long queue runs through a conference centre.
Six minutes after workshop registration opened its queue snaked throughout an entire floor of the conference centre.

Here’s what I got up to:


10 things that all WordPress plugin developers should avoid

David Artiss took the courageous step of installing 36 popular plugins onto a fresh WordPress site and was, unsurprisingly, immediately bombarded by a billion banners on his dashboard. Some were merely unhelpful (“don’t forget to add your API key”), others were annoying (“thanks for installing our plugin”), and plenty more were commercial advertisements (“get the premium version”) despite the fact that WordPress.org guidelines recommend against this. It’s no surprise that this kind of “aggressive promotion” is the single biggest annoyance that people reported when David asked around on social media.

Similarly, plugins which attempt to break the standard WordPress look-and-feel by e.g. hoisting themselves to the top of the menu, showing admin popovers, putting settings sections in places other than the settings submenu, and so on are a huge annoyance to everybody. I get sufficiently frustrated by these common antifeatures of plugins I use that I actually maintain a plugin for my own use that “fixes” the ones that aggrivate me the most!

A man wearing glasses and a t-shirt with a WordPress logo stands on a stage.
David raised lots of other common gripes with WordPress plugins, too: data validation failures, leaving content behind after uninstallation (and “deactivation surveys”, ugh!), and a failure to account for accessibility.

David’s promised to put his slides online, plus to write articles about everything that came up in his Q&A.

I’m unconvinced that we can rely on plugin developers to independently fix the kinds of problems that come high on David’s list. I wonder if there’s mileage in WordPress Core reimplementing the way that the main navigation menu works such that all items in it can be (easily) re-arranged by users to their own preference? This would undermine the perceived value to plugin developers of “hoisting” their own to the top by allowing users to counteract it, and would provide a valuable feature to allow site admins to streamline their workflow: use WooCommerce but only in a way that’s secondary to your blog? Move “Products” below “Posts”! Etc.

Why yes, I’m liveblogging this. And yes, I’m not using Gutenberg yet (that’s a whole other story…)

Where did we come from?

Aaron Reimann from ClockworkWP gave us a tour of how WordPress has changed over the course of its 20-year history, starting even slightly before I started using WordPress; my blog (previously powered by some hacky PHP, previouslier powered by some hackier Perl, previousliest written in static HTML) switched to WordPress in 2004, when it hit version 1.2, so it was fun to get the opportunity to see some even older versions illustrated.

A WordPress site, circa 2004, simulated in a virtual machine.
A WordPress site from 2004 would, of course, still be perfectly usable today. How many JS-heavy/API-driven websites of today do you reckon will still function in 20 years time?

It was great to be reminded how far the Core code has come over that time. Early versions of WordPress – as was common among PHP applications at the time! – had very few files and each could reliably be expected to be a stack of SQL, wrapped in a stack of code, wrapped in what’s otherwise a HTML file: no modularity!

A man wearing a flat cap strides across a stage.
Aaron’s passion for this kind of digital archaeology really shows. I dig it.

There were very few surprises for me in this talk, as you might expect for such an “old hand”, but I really enjoyed the nostalgia of exploring WordPress history through his eyes.

I enjoyed putting him on the spot with a “spicy” question at the end of his talk, by asking him if, alongside everything we’ve gained over the years, whether there’s anything we lost along the way. He answered well, pointing out that the somewhat bloated stack of plugins that are commonplace on big sites nowadays and the ease with which admins can just “click and install” more of them. I agree with him, although personally I miss built-in XFN support…

If you’d have told me in advance that hugging a Wapuu would have been a highlight of the day… yeah, that wouldn’t have been a surprise!

Networking And All That

There’s a lot of exhibitors with stands, but I tried to do a circuit or so and pay attention at least to those whose owners I’ve come into contact with in a professional capacity. Many developers who make extensions for WooCommerce, of course, sell those extensions through WooCommerce.com, which means they come into routine direct contact with my code (and it can mean that when their extension’s been initially rejected by our security scanners or linters, it’s me their developers first want to curse!).

After a while, to spare some of that awkward exchange where somebody tries to sell me their product before I explain that I already sell their product for them, I slapped a “Woo” sticker on my lanyard.

It’s been great to connect with people using WordPress to power the Web in a whole variety of different contexts, but it somehow still feels strange to me that WordPress has such a commercial following! Even speaking as somebody who’s made their living at least partially out of WordPress for the last decade plus, it still feels to me like its greatest value comes from its use for personal publishing.

The feel of a WordCamp with its big shiny sponsors is enormously different from, say, the intimacy and individuality of a Homebrew Website Club meeting, and I think that’s something I still need to come to terms with. WordPress’s success story comes from many different causes, but perhaps chief among them is the fact that it’s versatile enough to power the website of a government, multinational, or household-name brand… but also to run the smallest personal indie blog. I struggle to comprehend that, even with my background.

(Side note, Sophie Koonin says that building a personal website is a radical act in 2023, and I absolutely agree.)

A "Woo" booth, staffed with a variety of people, with Dan at the centre.
My division of Automattic had a presence, of course.

I was proud of my colleagues for the “gimmick” they were using to attract people to the Woo stand: you could pick up a “credit card” and use it to make a purchase (of Greek olive oil) using a website, see your order appear on the app at the backend in real-time, and then receive your purchase as a giveaway. The “credit card” doubles as a business card from the stand, the olive oil is a real product from a real, local producer (who really uses WooCommerce to sell online!), and when you provide an email address at the checkout you can opt-in to being contacted by the team afterwards. That’s some good joined-up thinking by my buddies in marketing!


WordPress extended: build unique websites on top of WP

Petya Petkova observed that it’s commonplace to take the easy approach and make a website look like… well, every other website.  “Web deja-vu” is a real thing, and it’s fed not only by the ebbs and flows of trends in web design but by the proliferation of indistinct themes that people just install-and-use.

A woman with long hair, wearing a green t-shirt, stands before a screen on a stage.
How can we break free from web deja-vu, asks Petya. It almost makes me sad that her slides had been coalesced into the conference’s slidedeck design rather than being her own… although on second though maybe that just helps enhance the point!

Choice of colours and typography can be used to tell a story, to instil a feeling, to encourage engagement. Scrolling can be used as a metaphor for storytelling (“scrolly-telling”, Petya calls it). Animation flow can be used to direct a user’s attention and drive focus and encourage interaction.

A lot of the technical concepts she demonstrated – parts of a page that scroll at different speeds, typography that shifts or changes, videos used in a subtle way to accentuate other content, etc. – can be implemented in the frontend with WebGL, Three.js and the like. Petya observes that moving this kind of content interactivity into the frontend can produce an illusion of a performance improvement, which is an argument I’ve heard before, but personally I think it’s only valuable if it’s built as a progressive enhancement: otherwise, you’re always at risk that your site won’t look like you’d hope.

I note, for example, that Petya’s agency’s site shows only an “endless spinner” when viewed in my browser (which blocks the code.jQuery CDN by default, unless allowlisted for specific sites). All of the content is there, on the page, if you View Source, but it’s completely invisible if an external JavaScript fails to load. That doesn’t just happen when weirdos like me disable JavaScript in their browsers: it can happen if the browser interacts badly with the script, or if the user’s Internet connection is ropey, or a malware scanner misfires, or if government censorship blocks the CDN, or in any number of other conditions.

Screenshot from acceler8design.com, showing an "endless spinner" and no content.
While I agree with Petya about the value of animation and interactivity to make sites awesome, I don’t think it can take second-place to ensuring the most-widespread access and accessibility for your audience. Otherwise we’d still be making Flash sites, right?

So yeah: uniqueness and creativity are great, and I like what she’s proposing, but not the way she goes about it. The first person to ask a question wisely brought up accessibility, and Petya answered well that accessibility technologies can bridge the gap, but I’d counter that it’s preferable to build accessible in the first instance: if you have to use an aria- attribute it’s a good sign that you probably already did something wrong (not always, but it’s certainly a pointer that you ought to take a step back and check!).

Several other good questions and great answers followed: about how to showcase a preliminary design when they design is dependent upon animation and interactivity (which I’ve witnessed before!), on the value of server-side rendering of components, and about how to optimise for smaller screens. Petya clearly knows her stuff in all of these areas and had confident responses.


State of WordPress security – insights from 2022

Oliver Sild is the kind of self-taught hacker, security nerd, and community builder that I love, so I wasn’t going to miss his talk.

A man in a literal black hat stands in the centre of a large theatre stage.
The number of security vulnerability reports in the WordPress ecosystem is up +328%, Oliver opened. But the bugs being reported are increasingly old, so we’re not talking about new issues being created. And only 0.3% of bugs were in WordPress Core (and were patched before they were exploitable).

It’s good news in general in WordPress Security-land… but CSRF is on the up-and-up (overtaking XSS) in the plugin space. That, and all the broken access control we see in the admin area, are things I’ll be keeping in mind next time I’m arguing with a vendor about the importance of using nonces and security checks in their extension (I have this battle from time to time!).

But an interesting development is the growth of the supply chains in the WordPress plugin ecosystem. Nowadays a plugin might depend upon another plugin which might depend upon a library… and a patch applied to the latter of those might take time to be propagated through the chain, providing attackers with a growing window of opportunity.

Sankey chart showing 1160 submitted bugs being separated into pending, accepted, invalid, and (eventually) patched. 26% of critical bugs in 2022 received no timely patch.
I love a good Sankey chart. Even when it says scary things.

A worrying thought is that while plugin directory administrators will pull and remove plugins that have longstanding unactioned security issues. But that doesn’t help the sites that already have that plugin installed and are still using it! There’s a proposal to allow WordPress to notify admins if a plugin used on a site has been dropped for security reasons, but it was opened 9 years ago and hasn’t seen any real movement, soo…

I like that Oliver plugged for security researchers being acknowledged as equal contributors to developers on your software. But then, I would say that, as somebody who breaks into things once in a while and then tells the affected parties how to fix the problem that allowed me to do so! He also provided a whole wealth of tips for site owners and agencies to try to keep their sites safe, but little that I wasn’t aware of already.

A large audience of a few hundred people, seen from above, facing left.
Still, good to see this talk get as good an audience as it did, given the importance of the topic!

It was about this point in the day, glancing at my schedule and realising that at any given time there were up to four other sessions running simultaneously, that I really got a feel for the scale of this conference. Awesome. Meanwhile, Oliver was fielding the question that I’m sure everybody was thinking: with Gutenberg blocks powered by JavaScript that are often backed by a supply-chain of the usual billion-or-so files you find in your .node_modules directory, isn’t the risk of supply chain attacks increasing?

Spoiler: yes. Did you notice earlier in this post I mentioned that I don’t use Gutenberg on this site yet?

Typographic readability in theme design & development

My first “workshop” was run by Giulia Laco, on the topic of readable content and design.

A title slide encourages designers to sit on the left (to the right of the speaker), developers to the right (on her left), and "no-coders" in the centre.
Designers to the left of me, coders to the right: here I am, stuck in the middle with you.

Giulia began by reminding us how short the attention span of Web readers is, and how important the right typographic choices are in ensuring that people actually read your content. I fully get this – I think that very few people will have the attention span to read this part of this very blog post, for example! – but I loved that she hammered the point home by presenting every slide of her presentation twice (or more), “improving” the typographic choices as she went along: an excellent and memorable quirk.

Our capacity to read and comprehend a text is affected by a combination of common (distance, lighting, environment, concentration, mood, etc.), personal (age, proficiency, motiviation, accessibility requirements, etc.), and typographic (face, style, size, line length and spacing, contrast, width, rhythm etc.) factors. To explore the impact of the typographic factors, the group dived into a pre-prepared Codepen and a shared Figma diagram. (I immediately had a TIL moment over the font-synthesis: CSS property!)

A presentation of the typography playground, in which the font is being changed.
I appreciated that Giulia stressed the importance of a fallback font. Just like the CDN issues I described above while talking about JavaScript dependencies, not specifying a fallback font puts your design at the mercy of the browser’s defaults. We don’t like to think about what happens when websites partially fail, but they do, and we should.

Things get interesting at the intersection of readability and accessibility. For example, WCAG accessibility requirements demand that you don’t use images of text (we used to do this a lot back before we could reliably use fonts on the web, and before we could easily have background images on e.g. buttons for navigation). But this accessibility requirement also aids screen readability when accounting for e.g. “retina” screens with virtual pixel ratios.

Slide showing a physical pixel and a "virtual pixel" representing a real pixel of a different size.
Do you remember when a pixel was the size of a pixel? Those days are long gone. True story.

Giulia provided a great explanation of why we may well think in pixels (as developers or digital designers) but we’re unlikely to use them everywhere: I’d internalised this lesson long ago but I appreciated a well-explained justification. The short of it is: screen zoom (that fancy zoom feature you use in your browser all the time, especially on mobile) and text zoom (the one you probably don’t use, or don’t use so much) are different things, and setting a pixel-based font size in the root node wrecks the latter, forcing some people with accessibility needs to use the former, which is likely to result in vertical scrolling. Boo!

I also enjoyed seeing this demo of how the different hyphenation-points in different languages (because of syllable stress) can impact on your wrapping points/line lengths when content is translated. This can affect any website, of course, because any website can be the target of automatic translation.

Plus, Giulia’s thoughts on the value of serifed fonts (even on digital displays) for improving typographic readability of the letters d, b, p and q which are often mirror- or rotationally-symmetric to one another in sans-serif fonts. It’s amazing to have something – in this case, a psychological letter transposition – pointed out that I’ve experienced but never pinned down the reason for, before. Neat!

It was a shame that this workshop took place late in the day, because many of the participants (including me) seemed to have flagging energy levels!


Altogether a great (but intense) day. Boggles my mind that there’s another one like it tomorrow.

WCEU23 – Contributor Day

Among the many perks of working for a company with a history so tightly-intertwined with that of the open-source WordPress project is that license to attend WordCamps – the biggest WordPress conferences – is basically a given.

Dan, wearing an Automattic "Let's make the Web a better place" t-shirt, stands in front of a banner welcoming attendees to WordCamp Europe Athens 2023.
So yeah, right now I’m in Athens for WordCamp Europe 2023.

It’s frankly a wonder that this is, somehow, my first WordCamp. As well as using it1 and developing atop it2, of course, I’ve been contributing to WordPress since 2004 (albeit only in a tiny way, and not at all for most of the last decade!).

A table placeholder labelled "WP-CLI". It and s handful of Coke cans and disposable coffee cups are picked-out in colour on an otherwise monochrome and blurred picture.
If you already know what WP-CLI is… let’s be friends.

Today is Contributor Day, a pre-conference day in which folks new and old get together in person to hack on WordPress and WordPress-adjacent projects. So I met up with Cem, my Level 4 Dragonslayer friend, and we took an ultra-brief induction into WP-CLI3 before diving in to try to help write some code.

Dan takes a selfie from a round table covered in laptops, with people hacking at them.
Contributor Days are about many things, but perhaps their biggest value comes from lowering the barrier to becoming a new contributor to an open-source project by sitting you right next to somebody who already knows it well.

So today, as well as meeting some awesome folks, I got to write an overly-verbose justification for a bug report being invalid and implement my first PR for WP-CLI: a bugfix for a strange quirk in output formatting.

Screenshot showing a user running `wp plugin update --all --no-color` but the output putting the word "Success" in green.
The bug I fixed is slightly hard to describe (and even harder to explain why it matters), but here’s a summary: when you run a WP-CLI command that first displays a table and then the result, the result is likely to always appear in colour even if you specify --no-color.

I hope to be able to continue contributing to WP-CLI. I learned a lot about it today, and while I don’t use it as much as I used to in my multisite-management days, I still really respect its power as a tool.

Did I mention lately how awesome my employers are? I promise my blog’s not always gonna be me shilling for them… but today it is.

Footnotes

1 Even with the monumental stack of custom code woven into DanQ.me, a keen eye will probably spot that it’s WordPress-powered.

2 Perhaps my proudest “built on WordPress” moment was my original implementation of OpenID for WordPress, back in 2005, which is completely obsolete now. But I’ve done plenty of other things, both useful (like the multisite installation used by the University of Oxford) and pointless (like making WordPress a CMS for Gemini, Gopher, and Finger) too over the last 20 years.

3 WP-CLI is… it’s like Drush but for WordPress, if that makes sense to you? If not: it’s a multifaceted command-line tool for installing, configuring, maintaining, and managing WordPress installations, and I’ve been in love with it for years.

What a great statue! Cache was very easy to find; despite its camo it was very visible as I walked along the adjacent path. Thanks for bringing me out of my way on my walk from my hotel to the conference I’m attending, and TFTC. Greetings from Oxfordshire, UK!

Walking from my hotel to the site of a conference I’m attending, this morning, I stopped to find this cache. It took an embarrassingly long time for me to spot this sneaky little container! Greetings from Oxford, UK, and TFTC!

Automattic Acquires ActivityPub Plugin for WordPress

This article is a repost promoting content originally published elsewhere. See more things Dan's reposted.

Automattic has acquired the ActivityPub plugin for WordPress from German developer Matthias Pfefferle, who will be joining the company to continue improving support for federated platforms. Pfefferle, who is also the author of the Webmention plugin, said his new role is to see how Automattic’s products can benefit from open protocols like ActivityPub.

This is so exciting I might burst. Want to know why?

  1. Matt Mullenweg‘s commitment to ActivityPub makes me happy. WordPress made Pingback and Trackback take off, back in the day, and I believe that – in the same way – Automattic can help make ActivityPub more accessible and mainstream too.
  2. Matthias Pfefferle is both an IndieWeb and an ActivityPub star; I use (and I’ve extented upon) a lot of code he’s written every day and I sponsor him on Github! The chance that we get to work directly together is pretty slim, but it’s a chance right?

Susan A. Kitchens expressed concern that this could increase the level of ActivityPub spam out there (which right now is very low). I worry about that too. But I’m still optimistic that we can make something awesome off the back of this acquisition and keep the interpersonal Web federated, the way it ought to be.
