Brigid by Kim Curran

I enjoyed Kim Curran’s debut novel, The Morrigan, so when I saw a copy of her brand new book in the local library, I snapped it up.

Like The Morrigan, Brigid is modern retelling of Irish mythology, but in a very different time period. Whereas The Morrigan was set in a mythical time of the Fomorians and the Tuatha Dé Danann, Brigid is set in the relatively recent past of early Christian Ireland.

I was curious to see which Brigid this book would be about: the pagan goddess or the Christian saint?

Both, it turns out. The protagonist is the saint, but the narrator is the goddess. And they interact. It’s a clever framing device and for the most part, it works.

There are cameos a-plenty from the Christian pantheon like Patrick and Brendan the navigator but this is not the hagiography we learned in school. All the usual miracles are present and accounted for, but any supernatural powers aren’t ascribed to a Christian deity.

The world of Brigid isn’t so far removed from the world of The Morrigan after all.

Brigid isn’t a ground-breaking book, and it didn’t grab me as much as The Morrigan but it’s an enjoyable read nonetheless.

A web font strategy

The Session has been online in some form since the late 1990s. That’s long before web fonts existed.

To begin with, Times New Roman was the only game in town if you wanted serif type on a website. When Microsoft introduced Georgia it was a godsend. A beautiful typeface designed by Matthew Carter for the screen. I put it right at the start of my font stack for The Session.

Later, web fonts came along. Boy, does that short sentence belie the drama! There were very heated discussions about whether web browsers should provide this ability at all, and what it would mean for type foundries.

Microsoft led the way with their prorietary EOT format. Then everyone agreed on WOFF. Finally we got WOFF2, Electric Boogaloo.

Perhaps more important than that, we got intermediaries. Typekit, Fontdeck, and then the big daddy, Google Fonts.

That’s pretty much the state of play today. Oh yeah, and we’ve got variable fonts now.

I remember Nick Sherman presenting the idea of variable fonts at an Ampersand event years ago. I remember thinking “great idea, but it’ll never happen.” Pure science fiction. I thought the same thing when I first saw a conference presentation about a miraculous image format called Scalable Vector Graphics.

Sometimes I like to stop and take stock of what we take for granted in web browsers now. Web fonts. Variable web fonts. SVG. Flexbox. Grid. Media queries. Container queries. Fluid typography. And I haven’t even mentioned how we were once limited to just 216 colours on the web.

Georgia

Given all the advances in web typography, you might be wondering how my font strategy for The Session changed over the years.

It didn’t.

I mean, sure, I added fluid typography. That was a natural extension of my love for liquid layouts and, later, responsive design. But the font stack itself? That was still Georgia all the way.

Y’see, performance has always been a top priority for The Session. If I was going to replace a system font with a web font that the user had to download, it really needed to be worth it.

Over the years I dabbled with different typefaces but none of them felt quite right to me. And I still think Georgia is a beautiful typeface.

“But your website will look like lots of other websites!” some may cry. That used to be true when all we had was system fonts. But now that web fonts have become the norm, it’s actually pretty unusual to see Georgia in the wild.

Lora

Recently I found a font I liked. Part of why I like it is that it shares a lot of qualities with Georgia. It’s Lora by Olga Karpushina and Alexei Vanyashin.

I started to dabble with it and began seriously contemplating using it on The Session.

It’s a variable font, which is great. But actually, I’m not using that many weights on The Session. I could potentially just use a non-variable variety. It comes in fixed weights of regular, medium, semibold, and bold.

Alas, the regular weight (400) is a bit too light and the medium weight (500) is a bit too heavy. My goldilocks font weight is more like 450.

Okay, so the variable font it is. That also allows me to play around with some subtle variations in weights. As the font size gets bigger for headings, the font weight can reduce ever so slightly. And I can adjust the overall font weight down in dark mode (there’s no grading feature in this font, alas).

Subsetting

Lora supports a lot of alphabets, which is great—quite a few alphabets turn up on The Session occasionally. But this means that the font file size is quite large. 84K.

Subsetting to the rescue!

I created a subset of Lora that has everything except Cyrillic, Greek, and Latin Extended-B. I created another subset that only has Cyrillic, Greek, and Latin Extended-B. Now I’ve got two separate font files that are 48K and 41K in size.

I wrote two @font-face declarations for the two files. They’ve got the same font-family (Lora), the same font-weight (400 700), and the same font-style (normal) but they’ve got different values for unicode-range. That way, browsers know to only use appropriate file when characters on the page actually match the unicode range.

The first file is definitely going to be used. The second one might not even be needed on most pages.

I want to prioritise the loading of that first subsetted font file so it gets referenced in a link element with rel="preload".

The switcheroo

As well as file size, my other concern was how the swapping from Georgia to Lora would be perceived, especially on a slow connection. I wanted to avoid any visible rejiggering of the content.

This is where size-adjust comes in, along with its compadres ascent-override and descent-override.

Rather than adjusting the default size of Lora to match that of Georgia, I want to do it the other way around; adjust the fallback font to match the web font.

Here’s how I’m doing it:

@font-face {
    font-family: 'Fallback for Lora';
    src: local('Georgia');
    size-adjust: 105.77%;
    ascent-override: 95.11%;
    descent-override: 25.9%;
}

And then my font stack is:

font-family: Lora, 'Fallback for Lora', Georgia, serif;

It’s highly unlikely that any device out there has a system font called “Fallback for Lora” so I can be pretty confident that the @font-face adjustment rules will only get applied to browsers that have the right local font, Georgia.

But where did those magic numbers come from for size-adjust, ascent-override, and descent-override?

They came from Katie Hempenius. As well as maintaing a repo of font metrics, she provides the formula needed to calculate all three values. Or you could use this handy tool to eyeball it.

With that, Georgia gets swapped out for Lora with a minimum of layout shift.

First-timers and repeat visitors

Even with the layout shift taken care of, do I want to serve up web fonts to someone on a slow connection?

It depends. Specifically, it depends on whether it’s their first time visiting.

The Session already treats first time visitors differently to repeat visitors. The first time you visit the site, critical CSS is embedded in the head of the HTML page instead of being referenced in an external style sheet. Only once the page has loaded does the full style sheet also get downloaded and cached.

I decided that my @font-face rules pointing to the web fonts are not critical CSS. If it’s your first time visiting, those CSS rules only get downloaded after the page is done loading.

And unless you’re on a fast connection, you won’t see Georgia get swapped out for Lora. That’s because I’ve gone with a font-display value of “optional”.

Most people use “swap”. Some people use “fallback”. You’ve got to be pretty hardcore to use “optional”.

But the next page you go to, or the next time you come to the site, you more than likely will see Lora straight away. That’s because of the service worker I’ve got quietly putting static assets into the Cache API: CSS, JavaScript, and now web fonts.

So even though I’m prioritising snappy performance over visual consistency, it’s a trade-off that only really comes into play for first visits.

Next

I’m pretty happy with the overall strategy. Still, I’m not going to just set it and forget it. I’ll be monitoring the CRUX data for The Session keeping a particular eye on cumulative layout shift.

Before adding web fonts, the cumulative layout shift on The Session was zero. I think I’ve taken all the necessary steps to keep it nice and low, but if I’m wrong I’ll need to revisit my strategy.

Update: Big thanks to Roel Nieskens—of Wakamai Fondue fame—who managed to get the file size of my main subsetted font down even further; bedankt!

The Artisanal Web | Another Rodeo

I feel very seen here. This describes how I built The Session:

There are still people building the web by hand, very much like we did it in the early days. They know all about what’s possible using modern tooling, yet they choose to expend their time and attention to the craft of doing it by hand. They care about the craft, and they care about what they’re making. They believe in their unique skill and vision over engagement strategies and analytics and content algorithms. They don’t need a platform, or they’ll build their own.

10 Thoughts On “AI,” February 2026 Edition | Whatever

  1. I don’t and won’t use “AI” in the text of any of my published work.
  2. I’m not worried about “AI” replacing me as a novelist.
  3. People in general are burning out on “AI.”
  4. I’m supporting human artists, including as they relate to my own work.
  5. “AI” is Probably Sticking Around In Some Form.
  6. “AI” is a marketing term, not a technical one, and encompasses different technologies.
  7. There were and are ethical ways to have trained generative “AI” but because they weren’t done, the entire field is suspect.
  8. The various processes lumped into “AI” are likely to be integrated into programs and applications that are in business and creative workflows.
  9. It’s all right to be informed about the state of the art when it comes to “AI.”
  10. Some people are being made to use “AI” as a condition of their jobs. Maybe don’t give them too much shit for it.

The Case for Blogging in the Ruins

Start a blog. Start one because the practice of writing at length, for an audience you respect, about things that matter to you, is itself valuable. Start one because owning your own platform is a form of independence that becomes more important as centralized platforms become less trustworthy. Start one because the format shapes the thought, and this format is good for thinking.

Pluralistic: The Reverse-Centaur’s Guide to Criticizing AI (05 Dec 2025) – Pluralistic: Daily links from Cory Doctorow

The promise of AI – the promise AI companies make to investors – is that there will be AIs that can do your job, and when your boss fires you and replaces you with AI, he will keep half of your salary for himself, and give the other half to the AI company.

That’s it.

That’s the $13T growth story that MorganStanley is telling. It’s why big investors and institutionals are giving AI companies hundreds of billions of dollars. And because they are piling in, normies are also getting sucked in, risking their retirement savings and their family’s financial security.

Now, if AI could do your job, this would still be a problem. We’d have to figure out what to do with all these technologically unemployed people.

But AI can’t do your job. It can help you do your job, but that doesn’t mean it’s going to save anyone money.

The Jeopardy Phenomenon – Chris Coyier

AI has the Jeopardy Phenomenon too.

If you use it to generate code that is outside your expertise, you are likely to think it’s all well and good, especially if it seems to work at first pop. But if you’re intimately familiar with the technology or the code around the code it’s generating, there is a good chance you’ll be like hey! that’s not quite right!

Not just code. I’m astounded by the cognitive dissonance displayed by people who say “I asked an LLM about {topic I’m familiar with}, and here’s all the things it got wrong” who then proceed to say “It was really useful when I asked an LLM for advice on {topic I’m not familiar with, hence why I’m asking an LLM for advice}.”

Like, if you know that the results are super dodgy for your own area of expertise, why would you think they’d be any better for, I don’t know, restaurant recommendations in a city you’ve never been to?

Escape Velocity: Break Free from Framework Gravity — Den Odell

React is no longer just a library. It’s a full ecosystem that defines how frontend developers are allowed to think.

Real talk!

Browsers now ship View Transitions, Container Queries, and smarter scheduling primitives. The platform keeps evolving at a fair pace, but most teams won’t touch these capabilities until React officially wraps them in a hook or they show up in Next.js docs.

Innovation keeps happening right across the ecosystem, but for many it only becomes “real” once React validates the approach. Which is fine, assuming you enjoy waiting for permission to use the platform you’re already building on.

Zing!

The critique isn’t that React is bad, but that treating any single framework as infrastructure creates blind spots in how we think and build. When React becomes the lens through which we see the web, we stop noticing what the platform itself can already do, and we stop reaching for native solutions because we’re waiting for the framework-approved version to show up first.

If your team’s evolution depends on a single framework’s roadmap, you are not steering your product; you are waiting for permission to move.

Why use React?

This isn’t a rhetorical question. I genuinely want to know why developers choose to build websites using React.

There are many possible reasons. Alas, none of them relate directly to user experience, other than a trickle-down justification: happy productive developers will make better websites. Citation needed.

It’s also worth mentioning that some people don’t choose to use React, but its use is mandated by their workplace (like some other more recent technologies I could mention). By my definition, this makes React enterprise software in this situation. My definition of enterprise software is any software that you use but that you yourself didn’t choose.

Inertia

By far the most common reason for choosing React today is inertia. If it’s what you’re comfortable with, you’d need a really compelling reason not to use it. That’s generally the reason behind usage mandates too. If we “standardise” on React, then it’ll make hiring more straightforward (though the reality isn’t quite so simple, as the React ecosystem has mutated and bifurcated over time).

And you know what? Inertia is a perfectly valid reason to choose a technology. If time is of the essence, and you know it’s going to take you time to learn a new technology, it makes sense to stick with what you know, even if it’s out of date. This isn’t just true of React, it’s true of any tech stack.

This would all be absolutely fine if React weren’t a framework that gets executed in browsers. Any client-side framework is a tax on the end user. They have to download, parse, and execute the framework in order for you to benefit.

But maybe React doesn’t need to run in the browser at all. That’s the promise of server-side rendering.

The front end

There used to be a fairly clear distinction between front-end development and back-end development. The front end consisted of HTML, CSS, and client-side JavaScript. The back end was anything you wanted as long as it could spit out those bits of the front end: PHP, Ruby, Python, or even just a plain web server with static files.

Then it became possible to write JavaScript on the back end. Great! Now you didn’t need to context-switch when you were scripting for the client or the server. But this blessing also turned out to be a bit of a curse.

When you’re writing code for the back end, some things matter more than others. File size, for example, isn’t really a concern. Your code can get really long and it probably won’t slow down the execution. And if it does, you can always buy your way out of the problem by getting a more powerful server.

On the front end, your code should have different priorities. File size matters, especially with JavaScript. The code won’t be executed on your server. It’s executed on all sorts of devices on all sorts of networks running all sorts of browsers. If things get slow, you can’t buy your way out of the problem because you can’t buy every single one of your users a new device and a new network plan.

Now that JavaScript can run on the server as well as the client, it’s tempting to just treat the code the same. It’s the same language after all. But the context really matters. Some JavaScript that’s perfectly fine to run on the server can be a resource hog on the client.

And this is where it gets interesting with React. Because most of the things people like about React still apply on the back end.

React developers

When React first appeared, it was touted as front-end tool. State management and a near-magical virtual DOM were the main selling points.

Over time, that’s changed. The claimed speed benefits of the virtual DOM turned out to be just plain false. That just left state management.

But by that time, the selling points had changed. The component-based architecture turned out to be really popular. Developers liked JSX. A lot. Once you got used to it, it was a neat way to encapsulate little bits of functionality into building blocks that can be combined in all sorts of ways.

For the longest time, I didn’t realise this had happened. I was still thinking of React as being a framework like jQuery. But React is a framework like Rails or Django. As a developer, it’s where you do all your work. Heck, it’s pretty much your identity.

But whereas Rails or Django run on the back end, React runs on the front end …except when it doesn’t.

JavaScript can run on the server, which means React can run on the server. It’s entirely possible to have your React cake and eat it. You can write all of your code in React without serving up a single line of React to your users.

That’s true in theory. The devil is in the tooling.

Priorities

Next.js allows you to write in React and do server-side rendering. But it really, really wants to output React to the client as well.

By default, you get the dreaded hydration pattern—do all the computing on the server in JavaScript (yay!), serve up HTML straight away (yay! yay!) …and then serve up all the same JavaScript that’s on the server anyway (ya—wait, what?).

It’s possible to get Next.js to skip that last step, but it’s not easy. You’ll be battling it every step of the way.

Astro takes a very different approach. It will do everything it can to keep the client-side JavaScript to a minimum. Developers get to keep their beloved JSX authoring environment without penalising users.

Alas, the collective inertia of the “modern” development community is bound up in the React/Next/Vercel ecosystem. That’s a shame, because Astro shows us that it doesn’t have to be this way.

Switching away from using React on the front end doesn’t mean you have to switch away from using React on the back end.

Why use React?

The titular question I asked is too broad and naïve. There are plenty of reasons to use React, just as there are plenty of reasons to use Wordpress, Eleventy, or any other technology that works on the back end. If it’s what you like or what you’re comfortable with, that’s reason enough.

All I really care about is the front end. I’m not going to pass judgment on anyone’s choice of server-side framework, as long as it doesn’t impact what you can do in the client. Like Harry says:

…if you’re going to use one, I shouldn’t be able to smell it.

Here’s the question I should be asking:

Why use React in the browser?

Because if the reason you’re using React is cultural—the whole team works in JSX, it makes hiring easier—then there’s probably no need to make your users download React.

If you’re making a single-page app, then …well, the first thing you should do is ask yourself if it really needs to be a single-page app. They should be the exception, not the default. But if you’re determined to make a single-page app, then I can see why state management becomes very important.

In that situation, try shipping Preact instead of React. As a developer, you’ll almost certainly notice no difference, but your users will appreciate the refreshing lack of bloat.

Mostly though, I’d encourage you to investigate what you can do with vanilla JavaScript in the browser. I totally get why you’d want to hold on to React as an authoring environment, but don’t let your framework limit what you can do on the front end. If you use React on the client, you’re not doing your users any favours.

You can continue to write in React. You can continue to use JSX. You can continue to hire React developers. But keep it on your machine. For your users, make the most of what web browsers can do.

Once you keep React on the server, then a whole world of possibilities opens up on the client. Web browsers have become incredibly powerful in what they offer you. Don’t let React-on-the-client hold you back.

And if you want to know more about what web browsers are capable of today, come to Web Day Out in Brighton on Thursday, 12th March 2026.

The premature sheen

I find Brian Eno to be a fascinating chap. His music isn’t my cup of tea, but I really enjoy hearing his thoughts on art, creativity, and culture.

I’ve always loved this short piece he wrote about singing with other people. I’ve passed that link onto multiple people who have found a deep joy in singing with a choir:

Singing aloud leaves you with a sense of levity and contentedness. And then there are what I would call “civilizational benefits.” When you sing with a group of people, you learn how to subsume yourself into a group consciousness because a capella singing is all about the immersion of the self into the community. That’s one of the great feelings — to stop being me for a little while and to become us. That way lies empathy, the great social virtue.

Then there’s the whole Long Now thing, a phrase that originated with him:

I noticed that this very local attitude to space in New York paralleled a similarly limited attitude to time. Everything was exciting, fast, current, and temporary. Enormous buildings came and went, careers rose and crashed in weeks. You rarely got the feeling that anyone had the time to think two years ahead, let alone ten or a hundred. Everyone seemed to be passing through. It was undeniably lively, but the downside was that it seemed selfish, irresponsible and randomly dangerous. I came to think of this as “The Short Now”, and this suggested the possibility of its opposite - “The Long Now”.

I was listening to my Huffduffer feed recently, where I had saved yet another interview with Brian Eno. Sure enough, there was plenty of interesting food for thought, but the bit that stood out to me was relevant to, of all things, prototyping:

I have an architect friend called Rem Koolhaas. He’s a Dutch architect, and he uses this phrase, “the premature sheen.” In his architectural practice, when they first got computers and computers were first good enough to do proper renderings of things, he said everything looked amazing at first.

You could construct a building in half an hour on the computer, and you’d have this amazing-looking thing, but, he said, “It didn’t help us make good buildings. It helped us make things that looked like they might be good buildings.”

I went to visit him one day when they were working on a big new complex for some place in Texas, and they were using matchboxes and pens and packets of tissues. It was completely analog, and there was no sense at all that this had any relationship to what the final product would be, in terms of how it looked.

It meant that what you were thinking about was: How does it work? What do we want it to be like to be in that place? You started asking the important questions again, not: What kind of facing should we have on the building or what color should the stone be?

I keep thinking about that insight: “It didn’t help us make good buildings. It helped us make things that looked like they might be good buildings.”

Substitute the word “buildings” for whatever output is supposedly being revolutionised by generative models today. Websites. Articles. Public policy.

Echoes of Connection · Matthias Ott

Matthias responds to my pondering about the point of “likes” and “shares”:

I like to think of Webmentions not as a measure of popularity. To me, they measure connection. Connection to individual people and connection to the community as a whole. Webmentions let you listen into the constant noise out there and, just like a radio telescope, pick up scarcely audible echoes of connection.

Responses

I had a very pleasant experience last week while I was reading through the RSS feeds I’m subscribed to. I came across two blog posts that were responding to blog posts of my own.

Robin Sloan wrote a post clarifying his position after I linked to him in my post about the slipperiness of the term “AI”.

Then Jim Nielsen wrote a deliciously satirical piece in response to my pithy little parable about research.

I love it when this happens!

Elizabeth Spiers recently wrote a piece called What Made Blogging Different?:

And if they wanted to respond to you, they had to do it on their own blog, and link back. The effect of this was that there were few equivalents of the worst aspects of social media that broke through.

It’s so true. I feel like a response from someone’s own website is exponentially more valuable than a response on Bluesky, Mastodon, Instagram, or any other social media platform.

Don’t get me wrong: I absolutely love the way that Brid.gy will send those social-media responses right back here to my own site in the form of webmentions. It also pings me whenever someone likes or shares a post of mine. But I’ve noticed that I’m not that interested in those anymore.

Maybe those low-investment actions were carried over from the old days of Twitter just because that’s the way things were always done, without us really asking whether they serve much purpose.

Right now I accept these likes and shares as webmentions. I display a tally of each kind of response under my posts. But I’m not sure why I’m doing it. I don’t particularly care about these numbers. I’m pretty sure no one else cares either.

If I cared, then they’d be vanity metrics. As it is they’re more like zombie metrics. I should probably just put them out of their misery.

Life Is More Than an Engineering Problem | Los Angeles Review of Books

A great interview with Ted Chiang:

Predicting the most likely next word is different from having correct information about the world, which is why LLMs are not a reliable way to get the answers to questions, and I don’t think there is good evidence to suggest that they will become reliable. Over the past couple of years, there have been some papers published suggesting that training LLMs on more data and throwing more processing power at the problem provides diminishing returns in terms of performance. They can get better at reproducing patterns found online, but they don’t become capable of actual reasoning; it seems that the problem is fundamental to their architecture. And you can bolt tools onto the side of an LLM, like giving it a calculator it can use when you ask it a math problem, or giving it access to a search engine when you want up-to-date information, but putting reliable tools under the control of an unreliable program is not enough to make the controlling program reliable. I think we will need a different approach if we want a truly reliable question answerer.

React Won by Default – And It’s Killing Frontend Innovation | Loren Stewart

React is no longer winning by technical merit. Today it is winning by default. That default is now slowing innovation across the frontend ecosystem.
