  450. <h2>History of the Web</h2>
  451. <p>I’m here to talk to you about the single biggest invention in human history. Some might say that invention is fire, or language. Some might say that it’s the printing press, or beer (actually, maybe it is beer). Some might say it’s the invention of electricity, or THE MASTERING OF THE ATOM.
  452. <p>Some others, perhaps less drunk on beer and easily accessible literature, might say that it’s the Internet (lower or uppercase “I”). But no, this talk is about the invention of the World Wide Web. The good old Dub Dub Dub. Or, as we all just call it in the late 2010’s - the Web. </p>

  458. <h3>Not a single invention</h3>
  459. <p>Despite what Tim Berners-Lee claims, the Web wasn’t a single invention <a href="#1">1</a>. Yes, we know that one man <em>says</em> that he invented it (grudging thanks to Tim), but he did so on the back of a thousand other technologies, inspired and enabled to build by their previous work.
  460. <p>The Web is incredible. It’s incredible because it’s stupid. It’s a collection of very stupid, or more accurately, very <em>simple</em>, technologies, all chained together to make something much greater.<a href="#2">2</a>
  461. <p>Let’s take a - very simplified! (and possibly horrendously simplified) - look at the history of the Web, and the simple technologies that allowed it to be built. Oh, and because we don’t want to be going all the way back to Mog hitting Gog over the head with a handy stone, and proclaiming that little patch of scrubland HIS (inadvertently inventing the first nation state) we’re just going to concentrate on the last 100 years.

  473. <p>Before the invention of the telegraph, messages to even the nearest city could take days. Messages to another country would take weeks, while messages to another <em>continent</em> would take months.
  474. <p>With the invention of telegraphs even the trans-continental message deliveries suddenly came down to <em>seconds</em>. Can you imagine how much of a headfuck that must have been? Months to seconds? People must have felt like they were living in science fiction.

  481. <p>With the invention of telegraphs we had the cultural idea of messaging-at-a-distance-via-electricity. It wasn’t too soon before the same kinda lines were being used to transmit voices. Add a primitive microphone and speaker, replicate that at the other end, and you were suddenly able to talk to people thousands of kilometers away.

  489. <p>Soon after telephones become commonplace we saw the rise of computers. Almost straight away people thought about getting them to talk to each other instead of humans having to do the boring talking.
  490. <p>This led to the invention of the modem, which as you can see in the slide, was at first a bulky device that you placed your phone speaker and microphone into. The computer would then scream down the phone to another computer, who would
  491. happily scream back, singing the song of their people. Computers could now talk to each other!

  498. <p>But bespoke one-on-one chat wasn’t enough for computers. No, they wanted group chats. Within a few years of the first modems the industry had standardised on a routine set of modem commands that allowed any computer to talk to any other computer. This was the <a href="https://en.wikipedia.org/wiki/Bulletin_board_system">Age of the BBS</a> and the invention of TCP/IP.
  499. <p>The TCP/IP specification, incidentally, gave us Postel’s Law, possibly one of the most beautiful Laws ever:

  546. <p>Especially HTML. It is strong because it is such a simple, <a href="https://en.wikipedia.org/wiki/Declarative_programming">declarative language</a>. It <em>requests</em> things from the browser. Flirts with it. It doesn’t <em>demand</em>, like other languages might.
  547. <aside class="comp-talk__note">
  548. <p>Technically, HTML is a domain-specific markup language that requests an outcome, and doesn’t care how that is accomplished. This is in stark contrast to imperative languages, which explicitly details what a program should do at every moment of its state.

  559. <p>Let’s just stop and think about that, because we take it for granted. I’m pulling chunks of code out of a running computer application, AND IT IS STILL WORKING.
  560. <p>Jut how… INCREDIBLE is that? Can you imagine pulling random chunks of code out of the memory of your iPhone or Windows laptop, and still expecting it to work? Of course not! But with HTML, it’s a given.

  634. <p>We <em>had</em> to learn about diversity of people and devices. We were forced to. Maybe not for the right reasons - we did it because we didn’t want to miss out on the market opportunity that mobile devices represented - but certainly with the right effect: we didn’t want to exclude people!

  675. <p>Most of this size is due to sites not offering srcset variants on their images, and not taking the time to optimise images on those that they do offer. Some of it is due to third-party tracking, advertising, and marketing scripts (marketeers may well be the most script-heavy people in any organisation).
  676. <p>A lot of it (but not most, by any means) is due to JS application bundles and third party scripts used to run a page (such as jQuery - still a major force on most of the web).

  750. <p>All of these things can cause a JS-dependent site to fall over and die, 100%. A site that should be robust in the face of all these things, because of the declarative and flexible nature of HTML and CSS, is now fragile and brittle.

  783. <div class="comp-talk__text">
  784. <h3>Suddenly exclusionary</h3>
  785. <p>We’re back to building sites that are not for everyone - huge, bloated sites, running fragile imperative code on the users local device. We have started to explicitly say “I think you should have this level of tech, processing power, and bandwidth before I think you’re eligible to use my site”.
  786. <p>Why? Because we want to have our fun with technology. Because we don’t want to think about “edge case” user needs.
  787. <p>“Edge case” is, to be frank, a phrase that should be banned from all developer conversations (and then tattooed onto the forehead of anyone who continues to use it).
  788. <p>When we say “Edge Case” we mean “Stress Case”. In their book, <a href="https://abookapart.com/products/design-for-real-life">Design for Real Life</a>, <a href="https://meyerweb.com/">Eric Meyer</a> &amp; <a href="https://www.sarawb.com/">Sara Wachter-Boettcher</a> point out that what we glibly call an “edge case” is normally an enormously stressful event for a user.
  789. <p>It often accompanies high emotions, stress, physical problems, financial problems, etc. When we discount and dismiss the “edge case”, we’re actually saying “I don’t care about that particular user’s stressful situation”.
  790. <p>n succinct example I saw recently was an American chap trying to use an airline website while holidaying in SE Asia. His flight had been cancelled and he were trying to rebook. However, due to terrible internet connectivity in his location the site just wasn’t loading - it was trying to pull down huge amounts of images and JS that were simply not happening on that connection.
  791. <blockquote class="twitter-tweet" data-lang="en"><p lang="en" dir="ltr"><a href="https://twitter.com/hashtag/webperf?src=hash&amp;ref_src=twsrc%5Etfw">#webperf</a> in Cambodia: Yesterday I tried to book a domestic flight through various booking platforms and airline sites.

  792. <p>He ended up calling a travel agent via telephone and rebooking. How much of an utter failure is your website if your drive someone off it and into another company’s hands?
  793. <p>Now imagine if that user had been able to disable Javascript and images and just have the HTML delivered. It wouldn’t have been pretty, but it would have <em>worked</em>.
  794. <p>I wondered about this, and went to check out the website in question.It turns out that no, you can’t. The website is fully JS-driven. If you disable JS then you just get a blank page.
  795. <p>On the same theme, here’s another example. An Angular JS app, failing because of flaky airport wifi.
  796. <blockquote class="twitter-tweet" data-cards="hidden" data-lang="en"><p lang="en" dir="ltr">Your fancy AngularJS apps are all very nice until you&#39;re trying to check in for a flight on flaky wifi: <a href="http://t.co/eTEXHE5XL2">pic.twitter.com/eTEXHE5XL2</a></p>&mdash; Matt Andrews (@mattpointblank) <a href="https://twitter.com/mattpointblank/status/595627536748535808?ref_src=twsrc%5Etfw">May 5, 2015</a></blockquote>
  797. <p>These are real situations, for real people. And these are only the ones that are reported, because the people in the stress situations are web professionals. How many thousands, millions, of interactions occur every day that no one reports because they’re “just” regular users?

  824. <p>Which is of course, absolute bollocks.
  825. <p>The truth is that empathy is a skill, a muscle, that can be exercised and made stronger. If you practise empathy every day and your ability to empathise will only get stronger! So here’s a few exercise lessons for you to take time to think about and practise.

  841. <p>It’s true, we’re rich. Even compared to our national peers we’re considered at least “well-off”. In comparison to the average person on this planet?: we are fucking <em>rolling</em> in money.
  842. <p>Yes, I know it doesn’t feel like that always. This statement certainly doesn’t account for personal circumstance or other axes of oppression (I will receive tweets about this, I know it). But as a rule of thumb, it’s a valid one. Techies are more well off than most other people.
  843. <p>The way we just buy technology, how we will happily splurge on an Alexa or a new laptop. The way we buy new toys on a whim. Check out the tech apparel of your coworkers next time you see them. This is not normal compared to most people on this planet.
  844. <p>I’m not saying this to make you feel bad. It’s just something that you should bear in mind. If you ever think “ffs, why don’t those users with old laptops and browsers just <em>upgrade</em>??” thentry and think about their circumstances. Ask “can they afford to do so?”, and “will upgrading their laptop or phone mean that they can’t eat this month?”.

  886. <h3>Lesson 4: Not everyone is able-bodied, or able-minded</h3>
  887. <p>Our final lesson. Not everyone is able-bodied, or neurotypical.
  888. <p>This is, like connectivity, heavily laden with stereotypes. Able-bodied people assume that a disability will manifest as someone using a wheelchair, or maybe as a completely blind person with a guide-dog.
  889. <p>But the reality is that disability covers a huge gamut of issues. Yes, wheelchair users and blind people are part of that. But a person does not have to be 100% a wheelchair user, nor do they have to be 100% blind. Percentages exist!
  890. <p>Disability also covers things like colour blindness, arthritis, motor control conditions such as Parkinsons or MS. It can be a neurological condition, such as ADHD, autism, or depression.
  891. <p>There are enormous varieties of disabilities. While you do not have to have a medical knowledge of each one, you must be aware of the range of problems.
  892. <p>Most importantly, you must be aware that everything you build could have an effect on any disability.

  917. <p>Yes, doorknobs. A weird analogy, but once again, please bear with me.
  918. <p>Now, both of these are lovely, beautiful things (as far as doorknobs go). Both of them are made from the same materials, both of them cost the same to manufacture.
  919. <p>However, one of them works for all people, while the other deliberately excludes huge segments of the population.
  920. <p>Such a simple thing, but offering a lever rather than a rotating knob means that the door becomes usable by people with arthritis, people who have hand or arm amputations, or people with hand/arm injuries.

  932. <p>So, given that both these doorknobs cost the same and look just as nice… well, what kind of fucking awful person would you be to deliberately <em>not</em> use the accessible version?
  933. <p>Similarly, when we build our websites we can build sites that are absolutely as beautiful as any other site, but we can choose to use techniques that work for everybody, in any condition.
  934. <p>Designing sites universally, designing them so that they work for people in the most stressful or dreadful situations, helps people in <em>all</em> situations.

  943. <h3>Basic research</h3>
  944. <p>So how do you start on this journey of building products that are robust and universal?
  945. <p>To me the first thing is to figure out your users core journey (or journeys). On every website the user is trying to accomplish <em>something</em>. <a href="#3">3</a>
  946. <p>Take, for example, a site for a new restaurant. What a visual treat to build! We can add sumptous photos of the food, we can add little animated waiters that march across the page, thrusting bowls of pasta into the air, while a full-screen video of the owner pleading with your to visit loads and plays in the background.
  947. <p>But in the end all the user wants to find out on the site is:
  948. <ul>
  949. <li>The address.
  950. <li>The opening times.
  951. <li>The menu options.
  952. </ul>
  953. <p>That’s it.
  954. <p>It’s same for every sector. Find our what your user needs first, then build around that. Developing anything more than that is just… pointless.
  955. <p>Hopefully you’ve got access to UX research for the product that you’re building. <a href="#4">4</a> If you don’t, stop right here and go sort that out before going any further.
  956. <aside class="comp-talk__note">
  957. <p id="3">[3] Well, maybe with the exception of advertising fluff sites - my condolences if that is what you must work on.
  958. <p id="4">[4] Okay, maybe not in your average advertising design agency. But, once again, I’m sorry that that is where you must sell your labour. But everywhere else, with products that have a <em>purpose</em>, you should have that.

  965. <h3>HTML</h3>
  966. <p>Now that we know them, get these core journeys quickly into HTML. And yes, I do mean <em>just</em> HTML, delivered fresh from the server.
  967. <p>Test <em>this</em> with your real users. Honestly! I know this may sound horrific to some (“we can’t show the user something <em>this</em> low fidelity!”) but HTML will form the basis your site! By testing the HTML, you’re testing the very foundation of your Robustness Pyramid. You’re testing the pure form - the <em>essence</em> - of your site.
  968. <p>When I say “this HTML will form your site” I mean that also. Don’t treat this as prototype code. Treat it as the first iteration of your website.
  969. <p>By designing with HTML initially you’re testing how your site works on the most fundamental level. You’re testing how it will work from an accessibility point of view. You’re testing how it will look to screenreaders. You’re testing how it will look in poor network conditions.
  970. <p>And you know what? This is 100% universal! Assuming you’ve built it using semantic HTML (and why <em>wouldn’t</em> you do that?) it will be completely accessible.
  971. <p>Now, let’s look at a real world example, from a project I recently worked on. Please prepare yourself, there is some unstyled HTML coming up.

  979. <p>With no styling, no javascript, and even no images, there is literally nothing to fail, bar the server that generates the HTML and the network that passes it to the server.
  980. <p>You can build this initial iteration using your backend language of choice. I like seeing a variety of backend languages. Diversity of technology is a great thing!
  981. <p>Of course, there’s nothing to stop you componentising everything right now. You don’t have to write raw HTML files by hand to do this! (well, you can - I ain’t here to spoil your masochistic fun). Anything that can compile fragments into HTML is great. :D

  989. <p>Now, this is a slightly more tricky one, as there’s a few ways of delivering CSS that works for everybody. But for this example I’m going to show a two-stage approach. There are other equally valid ways to do this, but I’ll concentrate on the two stage for now.
  990. <p>This means that you initially just add an an ultra basic stylesheet. Call this your Core stylesheet. It’s barely more than styled HTML. Maybe it will add a max-width to your main content to stop it going fluid across wide screens. But no more than that. It’s all flow content, running vertically down your page, with no positioning attempted.
  991. <p>It still works everywhere - it’s still 100% universal!

  1006. <p>But before we go on, a word from our sponsor, <a href="https://christianheilmann.com/">Chris Heilmann</a>. Take a look at some words that he barfed out:
  1007. <blockquote>“It’s not okay to block old browsers, but it’s a waste of time to support them 100%”</blockquote>
  1008. <p>Too right, Chris! Because you might think that what I’ve been suggesting is that we support all browsers 100% the same, no matter what. Even IE6!
  1009. <p>No no no, nothing is further from the truth. I’m lazy, just like every dev. I’m not going to waste time trying to make things look the same in Firefox or Chrome as a browser that even the manufacturer has left to die in the woods.
  1010. <p>No, the trick here is to choose a cut-off point. Especially if you are a large organisation. And the place I work - <a href="http://springernature.com">Springer Nature</a> - is very fucking large.

  1015. <div class="comp-talk__text">
  1016. <h3>Cutting the Mustard</h3>
  1017. <p>The BBC were pioneers in this. During their responsive redesign of the BBC News site they developed a novel technique called <a href="http://responsivenews.co.uk/post/18948466399/cutting-the-mustard">Cutting the Mustard</a> (CTM)
  1018. <p>What’s this? Well they serve up a core site: their HTML and some basicCSS - just the same as we developed in the previous section.
  1019. <p>Then they then check to see what JS capabilities the browser has. It’s just a few simple lines of JS. They use this as decider as to whether the browser is “core” or “advanced”.
  1020. <p>If it fails the test, then it’s core, and the user is presented with a fully working, but basically styled site. The styling is so simple, with no layout system, that it works on every browser ever made.
  1021. <p>However, if the test passes then a more advanced site is offered. It uses the same HTML and core stylesheet, but on top of that is layered another set of CSS and a large amount of lovely JS.
  1022. <p>Why do this? Well, the BBC want everyone to access their site. They are a public service broadcaster and are obligated, not just by <a href="/posts/progressive-enhancement">morals</a> and business sense, but by <a href="https://www.out-law.com/page-330">UK legislation</a> to produce a site that works for all.
  1023. <p>So how do you combine 100% universality with the fact that some people have ancient, terrible browsers that it would be a time-sink to support? CTM gives the answer! Only those browsers that are “good enough” receive the advanced features. Those that have poor technology support silently fail the test and receive the core version. No having to support ancient browsers!

  1028. <div class="comp-talk__text">
  1029. <h3>Springer Nature browser support chart</h3>
  1030. <p>Springer Nature (my wage payers) do something similiar to the BBC, but with a key difference. While the BBC do a CTM test based on JavaScript feature support, SN do a test based on a CSS media query.
  1031. <p>This media query cuts across very specific browser lines. You can see this in our <a href="https://github.com/springernature/frontend-playbook/blob/master/practices/graded-browser-support.md">graded browser support</a> table. In fact, it’s an exclusionary test, unlike the BBC version. It deliberately excludes those browsers marked as C-grade on our chart.
  1032. <p>C-grade browsers receive only our core stylesheet - again, fully working, just without advanced layout styling.
  1033. <p>Anything that isn’t C-grade receives our advanced stylesheet, and a much richer visual layout.
  1034. <p>So why do we have anything other than Grade C in our support table? Well, this is the part where being a popular site with a global audience comes in. We explicitly offer full support to those browsers that we deem as Grade A: generally the latest version -1.
  1035. <p>Grade X… well, grade X are between grade A and C. They probably <em>will</em> work with our advanced styling, but we can’t guarantee it.
  1036. <p>So why do we do it this way? Well, for us it’s a matter of stability. Our core audience - scientific and academic researchers - like stability. By fixing our browser support we can say to them <em>explicitly</em> what is supported and isn’t supported, and route any and all bugs/complaints/weirdnesses against that support table.

  1052. <p>Now is the point where we upgrade the forms so they post without doing a page refresh. Now is the time when we make pagination work without page reloads. Now is the time that we add in state management to our forms.

  1057. <div class="comp-talk__text">
  1058. <h3>Conditional JS</h3>
  1059. <p>Our CTM is done via CSS, so how do we replicate that in JS? Turns out that that there is a little-used <code>matchmedia</code> <a href="https://developer.mozilla.org/en-US/docs/Web/API/Window/matchMedia">window property</a>.
  1060. <p>It can be fed a media query directly, which is great. But even more usefully it can be fed a media query from your HTML. We therefore hook up our CTM media query to our JS via <code>matchMedia</code>.
  1061. <p>If our CTM test passes in CSS, and the CSS file loads, then our JS is loaded. Very neat, and very simple.
  1062. <p>Why do it like this? Well, we don’t want our JS to even <em>try</em> to run if it’s an old browser, and we don’t want it to run before our CSS, or if our CSS fails to load. Upgraded Javascript is unlikely to be useful if the associated CSS isn’t there.
  1063. <p>Once the JS is progressively loaded then we do lots of things. Add tabs, add animations, handle modal dialogs, etc. On this site the JS was relatively simple (but still modern and modularly written). But there’s no reason that it couldn’t be much more complex. As long as the base HTML site offers the core user journey then your JS can do lots of fancy extra things.

  1081. <p>It’s the ultimate in Lean UX.

  1088. <p>It’s also the ultimate in labour-saving. For real - you only build what you need. No bootstrapping into expensive frameworks. No taking on other peoples heavy systems.
  1089. <p>You only add more advanced things as they are proven necessary by user feedback and testing.

  1095. <h3>Fights FOMO</h3>
  1096. <p>And because you’re only adding what you <em>need</em> to the page, it’s a lovely FOMO fighting mechanism.
  1097. <p>Because we do get awfully excited by latest tech, don’t we?
  1098. <p>Rather than asking “does this help my users?”, we drop a lot of crap onto a page because we read about it on hackernews.

  1104. <div class="comp-talk__text">
  1105. <h3>KISS</h3>
  1106. <p>Because we really do build things too complex. We desperately try to keep up with the large companies like Facebook and Google, crying ourselves to sleep at night that we’re simply not as good as them. We seem to forget that they’re generally overstaffed with overpaid and underworked techboys, enormous huge engineering departments! For some reason we beat ourselves up for not “keeping up” with them!
  1107. <p>Oh, they’ve produced lots of lovely code for us to use. But with complexity comes fragility. They’ve got the resources to debug this stuff to hell. The rest of us generally haven’t. Keep it simple and save yourself the trouble.

  1113. <h3>Limitations?</h3>
  1114. <p>“But this can’t cope with modern techniques!” you might say.
  1115. <p>Sure it can. The biggest one you’re thinking of is likely state management. We do exactly the same thing as we did before. We make sure our forms work at a basic level in HTML, and then we enhance it.
  1116. <p>State management solutions like Redux work perfectly well on vanilla JS sites.
  1117. <p>It won’t work with something like React though, and I don’t cry about that.
  1118. <p>This is a distinct robust design pattern, which we feel is durable and doesn’t lock us into a limited-life framework that will get replaced by something else in a year or two.

  1126. <p>It excels in being robust and universal. It <em>always</em> works. Broken JS, blocked JS, no JS, poor networks, nothing can break this, because it relies on streamed HTML, and not all-or-nothing JS.
  1127. <p>It’s lightweight and <em>loves</em> low powered devices.

  1141. <h3>3G performance</h3>
  1142. <p>An incredibly easy one is to start simulating slow network conditions in your browser. You can do this in just one tab of Chrome (other browsers will vary) by opening the Network tab in dev tools and turning on “slow 3G”. Now you get to experience your site as the average person wandering around the average city does!
  1143. <p>If you’re not on Chrome then try using <a href="https://www.charlesproxy.com/">Charles Proxy</a>. A similar thing, but for your entire OS.

  1148. <div class="comp-talk__text">
  1149. <h3>Use real hardware</h3>
  1150. <p>If you can, test on real hardware. Your 3000€ Mac is vastly more than the average computer of most users. The iPhone X that you bought on the first day of sale is infinitely more powerful average phone that most people are making use of.
  1151. <p>Don’t assume everyone has these amazingly powerful supercomputers! Make sure that your site runs well on the average Lidl laptop, because <em>someone</em> will be using it on that, and cursing your lack of testing.
  1152. <p>Perhaps more relevant to the developer mindset - proving that your site can run on the lowest end computer means that your site will run like a bat out of hell on anything more powerful!

  1184. <h3>Yes they are</h3>
  1185. <p>I will always answer with “Yes they are!”. Because, sweetpea, you simply don’t know a users situation.
  1186. <p>Oh, you can guess at it. You can assume that they’re always sitting at their desk, or always on wifi, or have time to concentrate on your task.
  1187. <p>But <em>knowing</em> what their situation is? Uh uh, sorry, you don’t know that.
  1188. <p>They could be on a borrowed device. They could be using a work computer that they have no control over. They could have suffered a temporary or permanent disability. You simply don’t know!
  1189. <p>Look at it this way: you don’t just build cars that only work in the best conditions, do you? Imagine a car that only worked on a sunny day, on a flat road! Oh, how silly that would be. No, you build it so that it works in horrible weather, so that it works when driven over grass or a gravel dirt road. In the same way you don’t just build sites that only work in the best conditions.
  1190. <p>You’re a web developer. Your job is to make a site work for everyone, in all conditions.

  1211. <p>We’re the enablers and the defenders of that diversity.
