Anti-work | Go Make Things

But this obsession with hard work as a virtue, as a good and righteous thing to do, the glorification of toil and sweat and labor… that’s a tool the wealthy who don’t work for a living use to oppress those who do.

I concur.

Two Paradigms for Enhancing HTML Tags | That HTML Blog

This really gets to the heart of one of the biggest benefits of HTML web components: composability. You can nest your regular markup inside multiple custom elements; something that is can’t do.

The other exciting approach doesn’t exist yet: custom attributes. Again, they’d be a great way of using composability to turbo-charge your existing HTML in all sorts of ways.

Design and Engineering, As One · Matthias Ott

A thoughtful piece by Matthias that’s a must-read for both designers and developers.

No-stack web development – David Bushell – Web Dev (UK)

A stack is also technical debt, non-transferable knowledge, accelerated obsolescence, and vendor lock-in. That means fragility and overall unnecessary complication. Popular stacks inevitably turn into cargo cults that build in spite of the web, not for it.

The web platform does not require build toolchains. Always default to, and regress to, the fundamentals of CSS, HTML, and JavaScript. Those core standards are the web stack.

What we think is a decline in literacy is a design problem | Aeon Essays

The choice isn’t between books and screens. The choice is between intentional design and profitable chaos. Between habitats that cultivate human potential and platforms that extract human attention.

Gas Town and Bullet Hell – Petafloptimism

Matt has some smart reckons on the relationship between time and technology:

The factory bell, the railway timetable, the telegraph wire, the always-on smartphone — each imposed a new temporal discipline, each produced its own characteristic form of exhaustion, and each was eventually (partially, imperfectly) domesticated through a combination of regulation, design, and collective action.

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!

A programmer’s loss of identity - ratfactor

We value learning. We value the merits of language design, type systems, software maintenance, levels of abstraction, and yeah, if I’m honest, minute syntactical differences, the color of the bike shed, and the best way to get that perfectly smooth shave on a yak. I’m not sure what we’re called now, “heirloom programmers”?

Do I sound like a machine code programmer in the 1950s refusing to learn structured programming and compiled languages? I reject that comparison. I love a beautiful abstraction just as much as I love a good low-level trick.

If the problem is that we’ve painted our development environments into a corner that requires tons of boilerplate, then that is the problem. We should have been chopping the cruft away and replacing it with deterministic abstractions like we’ve always done. That’s what that Larry Wall quote about good programmers being lazy was about. It did not mean that we would be okay with pulling a damn slot machine lever a couple times to generate the boilerplate.

Magic

I don’t like magic.

I’m not talking about acts of prestidigitation and illusion. I mean the kind of magic that’s used to market technologies. It’s magic. It just works. Don’t think about it.

I’ve written about seamless and seamful design before. Seamlessness is often touted as the ultimate goal of UX—“don’t make me think!”—but it comes with a price. That price is the reduction of agency.

When it comes to front-end development, my distrust of magic tips over into being a complete control freak.

I don’t like using code that I haven’t written and understood myself. Sometimes its unavoidable. I use two JavaScript libraries on The Session. One for displaying interactive maps and another for generating sheet music. As dependencies go, they’re very good but I still don’t like the feeling of being dependant on anything I don’t fully understand.

I can’t stomach the idea of using npm to install client-side JavaScript (which then installs more JavaScript, which in turn is dependant on even more JavaScript). It gives me the heebie-jeebies. I’m kind of astonished that most front-end developers have normalised doing daily trust falls with their codebases.

While I’m mistrustful of libraries, I’m completely allergic to frameworks.

Often I don’t distinguish between libraries and frameworks but the distinction matters here. Libraries are bits of other people’s code that I call from my code. Frameworks are other people’s code that call bits of my code.

Think of React. In order to use it, you basically have to adopt its idioms, its approach, its syntax. It’s a deeper level of dependency than just dropping in a regular piece of JavaScript.

I’ve always avoided client-side React because of its direct harm to end users (over-engineered bloated sites that take way longer to load than they need to). But the truth is that I also really dislike the extra layer of abstraction it puts between me and the browser.

Now, whenever there’s any talk about abstractions someone inevitably points out that, when it comes to computers, there’s always some layer of abstraction. If you’re not writing in binary, you don’t get to complain about an extra layer of abstraction making you uncomfortable.

I get that. But I still draw a line. When it comes to front-end development, that line is for me to stay as close as I can to raw HTML, CSS, and JavaScript. After all, that’s what users are going to get in their browsers.

My control freakery is not typical. It’s also not a very commercial or pragmatic attitude.

Over the years, I’ve stopped doing front-end development for client projects at work. Partly that’s because I’m pretty slow; it makes more sense to give the work to a better, faster developer. But it’s also because of my aversion to React. Projects came in where usage of React was a foregone conclusion. I wouldn’t work on those projects.

I mention this to point out that you probably shouldn’t adopt my inflexible mistrustful attitude if you want a career in front-end development.

Fortunately for me, front-end development still exists outside of client work. I get to have fun with my own website and with The Session. Heck, they even let me build the occasional hand-crafted website for a Clearleft event. I get to do all that the long, hard stupid way.

Meanwhile in the real world, the abstractions are piling up. Developers can now use large language models to generate code. Sometimes the code is good. Sometimes its not. You should probably check it before using it. But some developers just YOLO it straight to production.

That gives me the heebie-jeebies, but then again, so did npm. Is it really all that different? With npm you dialled up other people’s code directly. With large language models, they first slurp up everyone’s code (like, the whole World Wide Web), run a computationally expensive process of tokenisation, and then give you the bit you need when you need it. In a way, large language model coding tools are like a turbo-charged npm with even more layers of abstraction.

It’s not for me but I absolutely understand why it can work in a pragmatic commercial environment. Like Alice said:

Knitting is the future of coding. Nobody knits because they want a quick or cheap jumper, they knit because they love the craft. This is the future of writing code by hand. You will do it because you find it satisfying but it will be neither the cheapest or quickest way to write software.

But as Dave points out:

And so now we have these “magic words” in our codebases. Spells, essentially. Spells that work sometimes. Spells that we cast with no practical way to measure their effectiveness. They are prayers as much as they are instructions.

I shudder!

But again, this too is nothing new. We’ve all seen those codebases that contain mysterious arcane parts that nobody dares touch. coughWebpackcough. The issue isn’t with the code itself, but with the understanding of the code. If the understanding of the code was in one developer’s head, and that person has since left, the code is dangerous and best left untouched.

This, as you can imagine, is a maintenance nightmare. That’s where I’ve seen the real cost of abstractions. Abstractions often really do speed up production, but you pay the price in maintenance later on. If you want to understand the codebase, you must first understand the abstractions used in the codebase. That’s a lot to document, and let’s face it, documentation is the first casuality of almost every project.

So perhaps my aversion to abstraction in general—and large language models in particular—is because I tend to work on long-term projects. This website and The Session have lifespans measured in decades. For these kinds of projects, maintenance is a top priority.

Large language model coding tools truly are magic.

I don’t like magic.

Your URL Is Your State

How often do we, as frontend engineers, overlook the URL as a state management tool? We reach for all sorts of abstractions to manage state such as global stores, contexts, and caches while ignoring one of the web’s most elegant and oldest features: the humble URL.

Most of What We Call Progress - Yusuf Aytas

Every engineer eventually overbuilds something. You think you’re being smart. You’re thinking ahead, building for growth and before you know it, you’ve created a system ten times heavier than your actual problem. That’s the trap. We keep designing for imaginary futures for scale that may never come and call it engineering. But it’s not engineering. It’s over-engineering.

The industry rewards it too. Nobody gets promoted for keeping things small and sane. You get promoted for complexity.

Live

I don’t get out to gigs as much as I’d like. But for some reason, the past week has been packed with live music.

On Tuesday I saw Ye Vagabonds. I’m particularly partial to their nice mandolin playing. It was a nice concert that felt like being in a Greenwich Village folk club in the ’60s. It’s great to see how popular Ye Vagabonds are with indie kids, even if I’m slightly perplexed by the extent of the popularity—see also Lankum.

On Thursday it was time for Robert Forster and his band. I’m a huge fan of The Go-Betweens, as well as Forster’s solo work. He gave us a thoroughly enjoyable show, interspersing some select Go-Betweens tracks, including quite a few off 16 Lovers Lane.

On Saturday Jessica and I made the journey over to Lewes to see The Wilderness Yet at the folk club. We know Rowan and Rosie from when they used to live ‘round here and it was lovely to see and hear them again.

Then last night we went out to see DakhaBrakha. The Ukrainian population of Brighton came out to give them a very warm welcome. The band themselves were, unsurprisingly, brilliant. Like I said last time they came to town:

Imagine if Tom Waits and Cocteau Twins came from Eastern Europe and joined forces. Well, DakhaBrakha are even better than that.

A good week of music from Ireland, Australia, England, and Ukraine.
