This is a really excellent four-part series on web performance that really dives into the technical details and asks all the right questions:

Running up against a paper cut bug feels a little bit like getting a physical one: not the end of the world, but certainly unpleasant. These types of tiny annoyances accrete over time, especially when no one is paying attention to them. In a single day of using my phone, I encounter dozens of these minor bugs that each annoy me just a little bit, making the task I’m trying to accomplish just a little bit more complicated.

This is a terrific and nuanced talk that packs a lot into less than twenty minutes.
(The secret sauce in transitional web apps is progressive enhancement.)

It sometimes feels like we end up testing the limitations of our tools rather than the content and design itself.
What Benjamin found—and I heartily agree—is that HTML prototypes give you the most bang for your buck:

Many, if not all, of our world’s most wicked problems are rooted in the excessive hiding of complexity behind illusions of simplicity—the relentless shielding of messy details in favor of easy-to-use interfaces.
But there’s always a tradeoff between complexity, truth, and control. The more details are hidden, the harder it is to understand how the system actually works. (And the harder it is to control). The map becomes less and less representative of the territory. We often trade completeness and control for simplicity. We’d rather have a map that’s easy to navigate than a map that shows us every single detail about the territory. We’d rather have a simple user interface than an infinitely flexible one that exposes a bunch of switches and settings. We don’t want to have to think too hard. We just want to get where we’re going.
Seamful and seamless design are reframed here as ethical and deceptive design:
Ethical design is like a glove. It obscures the underlying structure (i.e. your hand) but preserves some truth about its shape and how it works. Deceptive design is like a mitten. It obscures the underlying structure and also hides a lot about its shape and how it works.

Two-factor authentication is generally considered A Good Thing™️ when you’re logging in to some online service.
The word “factor” here basically means “kind” so you’re doing two kinds of authentication. Typical factors are:
- Something you know (like a password),
- Something you have (like a phone or a USB key),
- Something you are (biometric Black Mirror shit).
Asking for a password and an email address isn’t two-factor authentication. They’re two pieces of identification, but they’re the same kind (something you know). Same goes for supplying your fingerprint and your face: two pieces of information, but of the same kind (something you are).
None of these kinds of authentication are foolproof. All of them can change. All of them can be spoofed. But when you combine factors, it gets a lot harder for an attacker to breach both kinds of authentication.
The most common kind of authentication on the web is password-based (something you know). When a second factor is added, it’s often connected to your phone (something you have).
Every security bod I’ve talked to recommends using an authenticator app for this if that option is available. Otherwise there’s SMS—short message service, or text message to most folks—but SMS has a weakness. Because it’s tied to a phone number, technically you’re only proving that you have access to a SIM (subscriber identity module), not a specific phone. In the US in particular, it’s all too easy for an attacker to use social engineering to get a number transferred to a different SIM card.
Still, authenticating with SMS is an option as a second factor of authentication. When you first sign up to a service, as well as providing the first-factor details (a password and a username or email address), you also verify your phone number. Then when you subsequently attempt to log in, you input your password and on the next screen you’re told to input a string that’s been sent by text message to your phone number (I say “string” but it’s usually a string of numbers).
There’s an inevitable friction for the user here. But then, there’s a fundamental tension between security and user experience.
In the world of security, vigilance is the watchword. Users need to be aware of their surroundings. Is this web page being served from the right domain? Is this email coming from the right address? Friction is an ally.
But in the world of user experience, the opposite is true. “Don’t make me think” is the rallying cry. Friction is an enemy.
With SMS authentication, the user has to manually copy the numbers from the text message (received in a messaging app) into a form on a website (in a different app—a web browser). But if the messaging app and the browser are on the same device, it’s possible to improve the user experience without sacrificing security.
If you’re building a form that accepts a passcode sent via SMS, you can use the
autocomplete attribute with a value of “one-time-code”. For a six-digit passcode, your
input element might look something like this:
<input type="text" maxlength="6" inputmode="numeric" autocomplete="one-time-code">
With one small addition to one HTML element, you’ve saved users some tedious drudgery.
There’s one more thing you can do to improve security, but it’s not something you add to the HTML. It’s something you add to the text message itself.
Let’s say your website is example.com and the text message you send reads:
Your one-time passcode is 123456.
Add this to the end of the text message:
So the full message reads:
Your one-time passcode is 123456. @example.com #123456
The first line is for humans. The second line is for machines. Using the @ symbol, you’re telling the device to only pre-fill the passcode for URLs on the domain example.com. Using the # symbol, you’re telling the device the value of the passcode. Combine this with
autocomplete="one-time-code" in your form and the user shouldn’t have to lift a finger.
I’m fascinated by these kind of emergent conventions in text messages. Remember that the @ symbol and # symbol in Twitter messages weren’t ideas from Twitter—they were conventions that users started and the service then adopted.
You can add a URL for
/.well-known/change-password which redirects to the form a user would use to update their password. Browsers and password managers can then use this information if they need to prompt a user to update their password after a breach. I’ve added this to The Session.
Oh, and on that page where users can update their password, the
autocomplete attribute is your friend again:
<input type="password" autocomplete="new-password">
If you want them to enter their current password first, use this:
<input type="password" autocomplete="current-password">
All of the things I’ve mentioned—the
autocomplete attribute, origin-bound one-time codes in text messages, and a well-known URL for changing passwords—have good browser support. But even if they were only supported in one browser, they’d still be worth adding. These additions do absolutely no harm to browsers that don’t yet support them. That’s progressive enhancement.

A four-point checklist for inclusive design:
Are you a person that makes digital things for other people? Awesome—because this page is all about making things for people. There are four ways you can improve your creation for everybody. All four are testable, fixable and they improve usability for everybody.

Smart thinking from Sara to improve usability for keyboard users by using
aria-hidden="true" tabindex="-1" to skip duplicate links:
A good rule of thumb for similar cases is that if you have multiple consecutive links to the same page, there is probably a chance to improve keyboard navigation by skipping some of those links to reduce the number of tab stops to one. The less tab stops, the better, as long as it does not worsen or compromise on other aspects of usability.
I’ve cautiously implemented this pattern now over on The Session where snippets of comments had both a title link and a “more” link going to the same destination.

Some good thought morsels from Robin on product design:
Bad product design is when folks talk more about the UI than what the UI is built on top of.
There’s a lot of talk about how great design is invisible—mostly boring conversations with little substance—but! I think that’s true when it comes to product design.
Bad product design is when your interface looks like your org chart.

Two observations of websites on mobile devices today:
- They are beautifully designed, with great typography, clear branding, all optimized for readability.
- I had to install Firefox, Adblock Plus and uBlock Origin, as well as manually select and remove additional elements such as subscription overlays.
Both observations are the result of conscious design decisions.

We have to stop confusing the excesses of capitalism with the hallmarks of quality. Sometimes Google aren’t better, they’re just more pervasive.

Creating a PWA has saved a lot of kilobytes after the initial load by storing files on the device to reuse on subsequent requests – this in turn lowers the load time and carbon footprint on subsequent page views, making the website better for both people and planet. We’ve also enabled offline access, which significantly improves user experience for people in areas with patchy connections, such as mobile users on their commute.

If you add another advertisement to your pages, you generate more revenue. If you track your users better, now you can deliver tailored ads and your conversion rates are higher. If you restrict users from leaving your walled garden ecosystem, now you get all the juice from whatever attention they have.
The question is: At which point do we reach the breaking point?
And I think the answer is: We are very close.
Facebook. Twitter. Medium. All desparate to withhold content they didn’t even create until you cough up your personal details.

Testing on a <$100 Android device on a 3G network should be an integral part of testing your website. Not everyone is on a brand-new device or upgrades often, especially with the price point of a high-end phones these days.
When we design and build our websites with the outliers in mind, whether it’s for performance or even user experience, we build an experience that can be easy for all to access and use — and that’s what the web is about, access and information for all.

PWAs just work better than your typical mobile site. Period.
But bear in mind:
Maybe simply because the “A” in PWA stands for “app,” too much discussion around PWAs focuses on comparing and contrasting to native mobile applications. We believe this comparison (and the accompanying discussion) is misguided.

When I liveblogged Jason’s talk at An Event Apart in Chicago, I included this bit of reporting:
Jason proceeds to relate a long and involved story about buying burritos online from Chipotle.
Well, here is that story. It’s a good one, with some practical takeaways (if you’ll pardon the pun):
- Use HTML5 input features
- Support autofill
- Make autofill part of your test plans

The ellipsis is the new hamburger.
It’s disappointing that Apple, supposedly a leader in interface design, has resorted to such uninspiring, and I’ll dare say, lazy design in its icons. I don’t claim to be a usability expert, but it seems to me that icons should represent a clear intention, followed by a consistent action.
