A Few Notes on A Few Notes on The Culture

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

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

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

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

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

Alas, that link is dead. Linkrot, innit?

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

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

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

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

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

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

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

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

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

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

What Makes CSS Hard To Master - Tim Severien

CSS is simple, but not easy.

If we, as a community, start to appreciate the complexity of writing CSS, perhaps we can ask for help instead of blaming the language when we’re confused or stuck. We might also stop looking down on CSS specialists.

Creating websites with prefers-reduced-data | Polypane Browser for Developers

There’s no browser support yet but that doesn’t mean we can’t start adding prefers-reduced-data to our media queries today. I like the idea of switching between web fonts and system fonts.

Digital gardens let you cultivate your own little bit of the internet | MIT Technology Review

Some suggested that the digital garden was a backlash to the internet we’ve become grudgingly accustomed to, where things go viral, change is looked down upon, and sites are one-dimensional. Facebook and Twitter profiles have neat slots for photos and posts, but enthusiasts of digital gardens reject those fixed design elements. The sense of time and space to explore is key.

Performance and people

I was helping a client with a bit of a performance audit this week. I really, really enjoy this work. It’s such a nice opportunity to get my hands in the soil of a website, so to speak, and suggest changes that will have a measurable effect on the user’s experience.

Not only is web performance a user experience issue, it may well be the user experience issue. Page speed has a proven demonstrable direct effect on user experience (and revenue and customer satisfaction and whatever other metrics you’re using).

It struck me that there’s a continuum of performance challenges. On one end of the continuum, you’ve got technical issues. These can be solved with technical solutions. On the other end of the continuum, you’ve got human issues. These can be solved with discussions, agreement, empathy, and conversations (often dreaded or awkward).

I think that, as developers, we tend to gravitate towards the technical issues. That’s our safe space. But I suspect that bigger gains can be reaped by tackling the uncomfortable human issues.

This week, for example, I uncovered three performance issues. One was definitely technical. One was definitely human. One was halfway between.

The technical issue was with web fonts. It’s a lot of fun to dive into this aspect of web performance because quite often there’s some low-hanging fruit: a relatively simple technical fix that will boost the performance (or perceived performance) of a website. That might be through resource hints (using link rel=“preload” in the HTML) or adjusting the font loading (using font-display in the CSS) or even nerdier stuff like subsetting.

In this case, the issue was with the file format of the font itself. By switching to woff2, there were significant file size savings. And the great thing is that @font-face rules allow you to specify multiple file formats so you can still support older browsers that can’t handle woff2. A win all ‘round!

The performance issue that was right in the middle of the technical/human continuum was with images. At first glance it looked like a similar issue to the fonts. Some images were being served in the wrong formats. When I say “wrong”, I guess I mean inappropriate. A photographic image, for example, is probably going to best served as a JPG rather than a PNG.

But unlike the fonts, the images weren’t in the direct control of the developers. These images were coming from a Content Management System. And while there’s a certain amount of processing you can do on the server, a human still makes the decision about what file format they’re uploading.

I’ve seen this happen at Clearleft. We launched an event site with lean performant code, but then someone uploaded an image that’s megabytes in size. The solution in that case wasn’t technical. We realised there was a knowledge gap around image file formats—which, let’s face it, is kind of a techy topic that most normal people shouldn’t be expected to know.

But it was extremely gratifying to see that people were genuinely interested in knowing a bit more about choosing the right format for the right image. I was able to provide a few rules of thumb and point to free software for converting images. It empowered those people to feel more confident using the Content Management System.

It was a similar situation with the client site I was looking at this week. Nobody is uploading oversized images in order to deliberately make the site slower. They probably don’t realise the difference that image formats can make. By having a discussion and giving them some pointers, they’ll have more knowledge and the site will be faster. Another win all ‘round!

At the other end of continuum was an issue that wasn’t technical. From a technical point of view, there was just one teeny weeny little script. But that little script is Google Tag Manager which then calls many, many other scripts that are not so teeny weeny. Third party scripts …the bane of web performance!

In retrospect, it seems unbelievable that third-party JavaScript is even possible. I mean, putting arbitrary code—that can then inject even more arbitrary code—onto your website? That seems like a security nightmare!

Remember when I did a countdown of the top four web performance challenges? At the number one spot is other people’s JavaScript.

Now one technical solution would be to remove the Google Tag Manager script. But that’s probably not very practical—you’ll probably just piss off some other department. That said, if you can’t find out which department was responsible for adding the Google Tag Manager script in the first place, it might we well be an option to remove it and then wait and see who complains. If no one notices it’s gone, job done!

More realistically, there’s someone who’s added that Google Tag Manager script for their own valid reasons. You’ll need to talk to them and understand their needs.

Again, as with images uploaded in a Content Management System, they may not be aware of the performance problems caused by third-party scripts. You could try throwing numbers at them, but I think you get better results by telling the story of performance.

Use tools like Request Map Generator to help them visualise the impact that third-party scripts are having. Talk to them. More importantly, listen to them. Find out why those scripts are being requested. What are the outcomes they’re working towards? Can you offer an alternative way of providing the data they need?

I think many of us developers are intimidated or apprehensive about approaching people to have those conversations. But it’s necessary. And in its own way, it can be as rewarding as tinkering with code. If the end result is a faster website, then the work is definitely worth doing—whether it’s technical work or people work.

Personally, I just really enjoy working on anything that will end up improving a website’s performance, and by extension, the user experience. If you fancy working with me on your site, you should get in touch with Clearleft.

Dark mode revisited

I added a dark mode to my website a while back. It was a fun thing to do during Indie Web Camp Amsterdam last year.

I tied the colour scheme to the operating system level. If you choose a dark mode in your OS, my website will adjust automatically thanks to the prefers-color-scheme: dark media query.

But I’ve seen notes from a few friends, not about my site specifically, but about how they like having an explicit toggle for dark mode (as well as the media query). Whenever I read those remarks, I’d think “I’m really not sure I’ve got time to deal with adding that kind of toggle to my site.”

But then I realised, “Jeremy, you absolute muffin! You’ve had a theme switcher on your website for almost two decades now!”

Doh! I had forgotten about that theme switcher. It dates back to the early days of CSS. I wanted my site to be a demonstration of how you could apply different styles to the same underlying markup (this was before the CSS Zen Garden came along). Those themes are very dated now, but if you like you can view my site with a Zeldman theme or a sci-fi theme.

To offer a dark-mode theme for my site, all I had to do was take the default stylesheet, pull out the custom properties from the prefers-color-scheme: dark media query, and done. It took less than five minutes.

So if you want to view my site in dark mode, it’s one of the options in the “Customise” dropdown on every page of the website.
