WWC22 - Design Principles For The Web - YouTube

Here’s the video of the talk I gave in front of an enormous audience at the We Are Developers conference …using a backup slidedeck.

WWC22 - Design Principles For The Web

Backup

I’m standing on a huge stage in a giant hangar-like room already filled with at least a thousand people. More are arriving. I’m due to start speaking in a few minutes. But there’s a problem with my laptop. It connects to the external screen, then disconnects, then connects, then disconnects. The technicians are on the stage with me, quickly swapping out adaptors and cables as they try to figure out a fix.

This is a pretty standard stress dream for me. Except this wasn’t a dream. This was happening for real at the giant We Are Developers World Congress in Berlin last week.

In the run-up to the event, the organisers had sent out emails about providing my slide deck ahead of time so it could go on a shared machine. I understand why this makes life easier for the people running the event, but it can be a red flag for speakers. It’s never quite the same as presenting from your own laptop with its familiar layout of the presentation display in Keynote.

Fortunately the organisers also said that I could present from my own laptop if I wanted to so that’s what I opted for.

One week before the talk in Berlin I was in Amsterdam for CSS Day. During a break between talks I was catching up with Michelle. We ended up swapping conference horror stories around technical issues (prompted by some of our fellow speakers having issues with Keynote on the brand new M1 laptops).

Michelle told me about a situation where she was supposed to be presenting from her own laptop, but because of last-minute technical issues, all the talks were being transferred to a single computer via USB sticks.

“But the fonts!” I said. “Yes”, Michelle responded. Even though she had put the fonts on the USB stick, things got muddled in the rush. If you open the Keynote file before installing the fonts, Keynote will perform font substitution and then it’s too late. This is exactly what happened with Michelle’s code examples, messing them up.

“You know”, I said, “I was thinking about having a back-up version of my talks that’s made entirely out of images—export every slide as an image, then make a new deck by importing all those images.”

“I’ve done that”, said Michelle. “But there isn’t a quick way to do it.”

I was still thinking about our conversation when I was on the Eurostar train back to England. I had plenty of time to kill with spotty internet connectivity. And that huge Berlin event was less than a week away.

I opened up the Keynote file of the Berlin presentation. I selected File, Export to, Images.

Then I created a new blank deck ready for the painstaking work that Michelle had warned me about. I figured I’d have to drag in each image individually. The presentation had 89 slides.

But I thought it was worth trying a shortcut first. I selected all of the images in Finder. Then I dragged them over to the far left column in Keynote, the one that shows the thumbnails of all the slides.

It worked!

Each image was now its own slide. I selected all 89 slides and applied my standard transition: a one second dissolve.

That was pretty much it. I now had a version of my talk that had no fonts whatsoever.

If you’re going to try this, it works best if don’t have too many transitions within slides. Like, let’s say you’ve got three words that you introduce—by clicking—one by one. You could have one slide with all three words, each one with its own build effect. But the other option is to have three slides: each one like the previous slide but with one more word added. If you use that second technique, then the exporting and importing will work smoothly.

Oh, and if you have lots and lots of notes, you’ll have to manually copy them over. My notes tend to be fairly minimal—a few prompts and the occasional time check (notes that say “5 minutes” or “10 minutes” so I can guage how my pacing is going).

Back to that stage in Berlin. The clock is ticking. My laptop is misbehaving.

One of the other speakers who will be on later in the day was hoping to test his laptop too. It’s Håkon. His presentation includes in-browser demos that won’t work on a shared machine. But he doesn’t get a chance to test his laptop just yet—my little emergency has taken precedent.

“Luckily”, I tell him, “I’ve got a backup of my presentation that’s just images to avoid any font issues.” He points out the irony: we spent years battling against the practice of text-as-images on the web and now here we are using that technique once again.

My laptop continues to misbehave. It connects, it disconnects, connects, disconnects. We’re going to have to run the presentation from the house machine. I’m handed a USB stick. I put my images-only version of the talk on there. I’m handed a clicker (I can’t use my own clicker with the house machine). I’m quickly ushered backstage while the MC announces my talk, a few minutes behind schedule.

It works. It feels a little strange not being able to look at my own laptop, but the on-stage monitors have the presentation display including my notes. The unfamiliar clicker feels awkward but hopefully nobody notices. I deliver my talk and it seems to go over well.

I think I’ll be making image-only versions of all my talks from now on. Hopefully I won’t ever need them, but just knowing that the backup is there is reassuring.

Mind you, if you’re the kind of person who likes to fiddle with your slides right up until the moment of presenting, then this technique won’t be very useful for you. But for me, not being able to fiddle with my slides after a certain point is a feature, not a bug.

Why you should hire a frontend developer - Technology in government

This is a really good description of the role of a front-end developer.

That’s front end, not full stack.

User agents

I was on the podcast A Question Of Code recently. It was fun! The podcast is aimed at people who are making a career change into web development, so it’s right up my alley.

I sometimes get asked about what a new starter should learn. On the podcast, I mentioned a post I wrote a while back with links to some great resources and tutorials. As I said then:

For web development, start with HTML, then CSS, then JavaScript (and don’t move on to JavaScript too quickly—really get to grips with HTML and CSS first).

That’s assuming you want to be a good well-rounded web developer. But it might be that you need to get a job as quickly as possible. In that case, my advice would be very different. I would advise you to learn React.

Believe me, I take no pleasure in giving that advice. But given the reality of what recruiters are looking for, knowing React is going to increase your chances of getting a job (something that’s reflected in the curricula of coding schools). And it’s always possible to work backwards from React to the more fundamental web technologies of HTML, CSS, and JavaScript. I hope.

Regardless of your initial route, what’s the next step? How do you go from starting out in web development to being a top-notch web developer?

I don’t consider myself to be a top-notch web developer (far from it), but I am very fortunate in that I’ve had the opportunity to work alongside some tippety-top-notch developers at ClearleftTrys, Cassie, Danielle, Mark, Graham, Charlotte, Andy, and Natalie.

They—and other top-notch developers I’m fortunate to know—have something in common. They prioritise users. Sure, they’ll all have their favourite technologies and specialised areas, but they don’t lose sight of who they’re building for.

When you think about it, there’s quite a power imbalance between users and developers on the web. Users can—ideally—choose which web browser to use, and maybe make some preference changes if they know where to look, but that’s about it. Developers dictate everything else—the technology that a website will use, the sheer amount of code shipped over the network to the user, whether the site will be built in a fragile or a resilient way. Users are dependent on developers, but developers don’t always act in the best interests of users. It’s a classic example of the principal-agent problem:

The principal–agent problem, in political science and economics (also known as agency dilemma or the agency problem) occurs when one person or entity (the “agent”), is able to make decisions and/or take actions on behalf of, or that impact, another person or entity: the “principal”. This dilemma exists in circumstances where agents are motivated to act in their own best interests, which are contrary to those of their principals, and is an example of moral hazard.

A top-notch developer never forgets that they are an agent, and that the user is the principal.

But is it realistic to expect web developers to be so focused on user needs? After all, there’s a whole separate field of user experience design that specialises in this focus. It hardly seems practical to suggest that a top-notch developer needs to first become a good UX designer. There’s already plenty to focus on when it comes to just the technology side of front-end development.

So maybe this is too simplistic a way of defining the principle-agent relationship between users and developers:

user :: developer

There’s something that sits in between, mediating that relationship. It’s a piece of software that in the world of web standards is even referred to as a “user agent”: the web browser.

user :: web browser :: developer

So if making the leap to understanding users seems too much of a stretch, there’s an intermediate step. Get to know how web browsers work. As a web developer, if you know what web browsers “like” and “dislike”, you’re well on the way to making great user experiences. If you understand the pain points for browser when they’re parsing and rendering your code, you’ve got a pretty good proxy for understanding the pain points that your users are experiencing.

CSS Architecture for Modern JavaScript Applications - MadeByMike

Mike sees the church of JS-first ignoring the lessons to be learned from the years of experience accumulated by CSS practitioners.

As the responsibilities of front-end developers have become more broad, some might consider the conventions outlined here to be not worth following. I’ve seen teams spend weeks planning the right combination of framework, build tools, workflows and patterns only to give zero consideration to the way they architect UI components. It’s often considered the last step in the process and not worthy of the same level of consideration.

It’s important! I’ve seen well-planned project fail or go well over budget because the UI architecture was poorly planned and became un-maintainable as the project grew.

What Makes a Mid-Level Developer? | Amber’s Website

I love the way that Amber is documenting her journey—I think this is so useful for others making the progression from junior to mid-level developer.

Priorities

I recently wrote about a web-specific example of a general principle for choosing the right tool for the job:

JavaScript should only do what only JavaScript can do.

I was—yet again—talking about appropriateness. Use the right technology for the task at hand. Here’s the example I gave:

It feels “wrong” when a powerful client-side JavaScript framework is applied to something that could be accomplished using HTML. Making a blog that’s a single page app is over-engineering.

Surprisingly, I got some pushback on this. Šime Vidas wrote:

Based on my experience, this is not necessarily the case.

Going from server-side rendering and progressive enhancement via JS to a single-page app powered by a JS framework was a enormous reduction in complexity for me (so the opposite of over-engineering).

(Emphasis mine.) He goes on to say:

My main concerns are ease of use & maintainability. If you get those things right, you’re good and it’s not over-engineering.

There’s no doubt that maintainability is a desirable goal. And ease of use for the developer is also important …but I think they pale in comparison to ease of use for the end user.

To be fair, the specific use-case I mentioned was making a blog. And a blog is a personal thing. You can do whatever the heck you like on your own website and don’t let anyone tell you otherwise.

So I probably chose a poor example to illustrate my point. I was thinking more about when you’re making websites for a living. You’re being paid money to make something available on the web. In that situation, I strongly believe that user needs should win out over developer convenience.

I wrote about this recently:

As a user-centred developer, my priority is doing what’s best for end users. That’s not to say I don’t value developer convenience. I do. But I prioritise user needs over developer needs. And in any case, those two needs don’t even come into conflict most of the time.

That’s why I responded to Šime, saying:

Your main concern should be user needs—not your own.

When I talk about over-engineering, I’m speaking from the perspective of end users, not developers.

Before considering your ease of use, and maintainability, consider users first.

In fairness to Šime, he’s being very open and honest about his priorities. I admire that. I’ve seen too many developers try to provide user experience justifications for decisions made for developer convenience. Once again I recommend Alex’s excellent article, The “Developer Experience” Bait-and-Switch:

The swap is executed by implying that by making things better for developers, users will eventually benefit equivalently. The unstated agreement is that developers share all of the same goals with the same intensity as end users and even managers. This is not true.

Now I worry I wasn’t specific enough when I talked about choosing appropriate technology:

Appropriateness is something I keep coming back to when it comes to evaluating web technologies. I don’t think there are good tools and bad tools; just tools that are appropriate or inapropriate for the task at hand.

I should have made it clear that I was talking about what is appropriate or inapropriate for users. I think I made the mistake of assuming that this was obvious, and didn’t need saying. I’ll try not to make that mistake again.

There’s a whole group of tools where this point isn’t even relevant—build tools, task runners, version control …anything that never directly touches the end user; use whatever works for you. But if you’re making decisions around HTML, ARIA, CSS, or JavaScript, then appropriateness for the end user should take precedence.

If you’re in that situation—you are being paid money to make websites, and you are making technology decisions—I urge you to remember Charlie’s words: it isn’t about you.

Ooops, I guess we’re full-stack developers now.

Chris broke both his arms just to avoid speaking at the JAMstack conference in London. Seems a bit extreme to me.

Anyway, to make up for not being there, he made a website of his talk. It’s good stuff, tackling the split.

It’s cool to see the tech around our job evolve to the point that we can reach our arms around the whole thing. It’s worthy of some concern when we feel like complication of web technology feels like it’s raising the barrier to entry

7 absolute truths I unlearned as junior developer

This is a wonderfully written post packed with hard-won wisdom.

This are the myths that Monica dispelled for herself:

  1. I’m a senior developer
  2. Everyone writes tests
  3. We’re so far behind everyone else (AKA “tech FOMO”)
  4. Code quality matters most
  5. Everything must be documented!!!!
  6. Technical debt is bad
  7. Seniority means being the best at programming

I’m a Web Designer - Andy Bell

Something that I am increasingly uncomfortable with is our industry’s obsession with job titles. I understand that the landscape has gotten a lot more complex than when I started out in 2009, but I do think the sheer volume and variation in titles isn’t overly helpful in communicating what people actually do.

I share Andy’s concern. I kinda wish that the title for this open job role at Clearleft could’ve just said “Person”.

“Designer + Developer Workflow,” an article by Dan Mall

Dan compares the relationship between a designer and developer in the web world to the relationship between an art director and a copywriter in the ad world. He and Brad made a video to demonstrate how they collaborate.

PWA: Progressive Web All-the-things - Tales of a Developer Advocate by Paul Kinlan

Very valuable observations from Paul on his travels, talking to developers and business people about progressive web apps—there’s some confusion out there.

My personal feeling is that everyone is really hung up on the A in PWA: ‘App’. It’s the success and failure of the branding of the concept; ‘App’ is in the name, ‘App’ is in the conscious of many users and businesses and so the associations are quite clear.

I Don’t Believe in Full-Stack Engineering • Robin Rendle

A good ol’ rant from Robin.

HTML and CSS and JavaScript have always been looked down upon by many engineers for their quirks. When they see a confusing and haphazardly implemented API across browsers (HTML/CSS/JS), I see a swarming, writhing, and constantly improving interface that means we can read stuff that was written fifteen years ago and our browsers can still parse it.

Before jumping to conclusions, read the whole thing. Robin isn’t having a go at people who consider themselves full-stack developers; he’s having a go at the people who are only hiring back-end developers and expecting them to automatically be “full stack.”

Developer happiness considered harmful (sometimes)

Thoughts on my favourite design principle (because I’m that much of a design principles nerd that I have a favourite).

Developer happiness is only a benefit if it first does no harm to others. Even better if it genuinely amplifies benefits to those further up chain of priorities.

SA Labs | Just a Developer

I like this distinction between coders and developers.

The Coder is characterized by his proficiency in a narrow range of chosen skills.

By contrast the Developer’s single greatest skill is in being an applied learner.

I’m definitely not a coder. Alas, by this criterion, I’m also not a developer (because I do not pick things up fast):

Quite simply the Developer has a knack for grokking new [languages|frameworks|platforms] and becoming proficient very quickly.

I prefer Charlie’s framing. It’s not about speed, it’s about priorities:

I’m not a “developer” in that I’m obsessed with code and frameworks. I’m a “developer” as in I develop the users experience for the better.

Full-Stack Developers | Brad Frost

In my experience, “full-stack developers” always translates to “programmers who can do frontend code because they have to and it’s ‘easy’.” It’s never the other way around. The term “full-stack developer” implies that a developer is equally adept at both frontend code and backend code, but I’ve never in my personal experience witnessed anyone who truly fits that description.

Down with the tool fetish - QuirksBlog

PPK responds in his typically strident way to posts by Tim and Bastian. I don’t agree with everything here, but I very much agree with this:

It’s not about what works for you. It’s about what works for your users.

If a very complicated set-up with seven brand-new libraries and frameworks and a bunch of other tools satisfies you completely as a web developer but slows your sites down to a crawl for your users, you’re doing it wrong.

If serving your users’ needs requires you to use other tools than the ones you’d really like to use, you should set your personal preferences aside, even though it may make you feel less good. You have a job to do.

But it’s worth remembering this caveat too.

Instagram to third-party developers: drop dead - Zeldman on Web & Interaction Design

Jeffrey’s right. Instagram’s new deal with developers is openly hostile. It probably means the end of OwnYourGram in its current form …a service whose existence is frankly the only reason I’m able to use Instagram at all.
