Seriously, though. What is a progressive web app? – Amberley Romo – Medium

What an excellent question! And what an excellent bit of sleuthing to get to the bottom of it. This is like linguistic spelunking on the World Wide Web.

Oh, and of course I love the little sidenote at the end.

Progressive Web Games – Mozilla Hacks – the Web developer blog

I was just talking about how browser-based games are the perfect use-case for service workers. Andrzej Mazur breaks down how that would work:

  • Add to Home screen
  • Offline capabilities
  • Progressive loading

Welcoming Progressive Web Apps to Microsoft Edge and Windows 10 - Microsoft Edge Dev BlogMicrosoft Edge Dev Blog

It’s really great to hear about how Microsoft will be promoting progressive web apps as first-class citizens …but it’s really unhelpful that they’re using this fudgy definition:

Progressive Web Apps are just great web sites that can behave like native apps—or, perhaps, Progressive Web Apps are just great apps, powered by Web technologies and delivered with Web infrastructure.

Although they also give a more technical definition:

Technologically speaking, PWAs are web apps, progressively enhanced with modern web technologies (Service Worker, Fetch networking, Cache API, Push notifications, Web App Manifest) to provide a more app-like experience.

Nice try, slipping notifications in there like that, but no. No, no, no. Let’s not fool ourselves into thinking that one of the most annoying “features” of native apps is even desirable on the web.

If you want to use notifications, fine. But they are absolutely not a requirement for a progressive web app.

(A responsive design, on the other hand, totally is.)

Safari 11.1

Squee! The next time there’s an update for OS X and iOS, Safari will magically have service worker support! Not only that, but Safari on iOS will start using the information in web app manifests for adding to home screen.

That’s an impressive turnaround.

Salva de la Puente - What is a PWA

Here’s a nice one-sentence definition for the marketing folk:

A Progressive Web App is a regular website following a progressive enhancement strategy to deliver native-like user experiences by using modern Web standards.

But if you’re talking to developers, I implore you to concretely define a Progressive Web App as the combination of HTTPS, a service worker, and a Web App Manifest.

Betting on the Web

Along the lines of John’s recent post, Henrik makes the business case for progressive web apps.

He also points out how they can be much better than native apps for controlling hardware.

They can be up and running in a fraction of the time whether or not they were already “installed” and unlike “apps” can be saved as an app on the device at the user’s discretion!

Essentially they’re really great for creating “ad hoc” experiences that can be “cold started” on a whim nearly as fast as if it were already installed.

Yes, That Web Project Should Be a PWA · An A List Apart Article

A fantastic piece by Aaron who—once again—articulates what I’ve been thinking:

Your site—every site—should be a PWA.

He clearly explains the building blocks of progressive web apps—HTTPS, a manifest file, and a service worker—before describing different scenarios for different kinds of sites:

  • Informational
  • Periodical
  • Transactional
  • Social
  • Software
  • Institutional

Progressive Web Apps may seem overly technical or beyond the needs of your project, but they’re really not. They’re just a shorthand for quality web experiences—experiences that can absolutely make a difference in our users’ lives.

Highly recommended!

If research on biases has told us anything, it is that humans make better decisions when we learn to recognize and correct for bias.

I’m a woman in computer science. Let me ladysplain the Google memo to you. - Vox

Cynthia Lee didn’t write the clickbaity headline, but she did write the superb article that follows it, methodically taking the manifestbro apart:

Its quasi-professional tone is a big part of what makes it so beguiling (to some) and also so dangerous. Many defenders seem genuinely baffled that a document that works so hard to appear dispassionate and reasonable could provoke such an emotional response.

This is what I was trying to get at with my post, but here it is explained far more clearly, calmly, and rationally.

In the end, focusing the conversation on the minutiae of the scientific claims in the manifesto is a red herring. Regardless of whether biological differences exist, there is no shortage of glaring evidence, in individual stories and in scientific studies, that women in tech experience bias and a general lack of a welcoming environment, as do underrepresented minorities. Until these problems are resolved, our focus should be on remedying that injustice.

If you want to debate the Googler’s Manifesto and you’re also a good person

We men face shame and firing if we say the wrong thing. Women face the same plus rape threats, death threats, and all kinds of sustained harassment. So women can’t speak up safely and therefore they would have to watch their male colleagues discuss how a woman’s brain determines her interests. How impossibly maddening that would be.

I’m a Google Manufacturing Robot and I Believe Humans Are Biologically Unfit to Have Jobs in Tech - McSweeney’s Internet Tendency

Normally a McSweeney’s piece elicits a wry chuckle, but this one had me in stitches.

Humans are also far more likely to “literally cannot right now.” I have never met an automaton that literally could not, though I have met some that theoretically would not and hypothetically might want to stop.

Silicon Valley’s weapon of choice against women: shoddy science | Angela Saini | Opinion | The Guardian

Those who want to use science to support their views – especially if they seek to undermine equality efforts in the workplace – must make an effort to fully inform themselves about the science of human nature. They may be disappointed to learn that it’s not as simple as they think.

A Brief History of Women in Computing – Faruk Ateş

An excellent rebuttal of that vile manifestbro, and an informative history lesson to boot.

You can’t cherry-pick a couple of scientific studies you like and use them to justify your arguments against diversity programs, while carefully ignoring the mountains of other scientific studies that show both how and why diversity programs are good, beneficial to all, and worth investing in.

I wish I could be this calm in refuting pseudoscientific bollocks, but I get so worked up by it that I’d probably undermine my own message. I’m glad that Faruk took the time to write this down.

Introducing PWAs

How to turn your website into a PWA | Max Böck - Frontend Web Developer

This primer on progressive web apps starts by dispelling some myths:

  1. Your thing does not have to be an “Application” to be a PWA.
  2. Your thing does not have to be a Javascript-powered single page app.
  3. PWAs are not specifically made for Google or Android.
  4. PWAs are ready and safe to use today.

Then it describes the three-step programme for turning your thing into a progressive web app:

  1. The Manifest.
  2. Go HTTPS.
  3. The Service Worker.

Your Site—Any Site—Should be a PWA | Aaron Gustafson

Tell it, brother!

PWAs don’t require you use a particular JavaScript framework or any JavaScript framework at all. You don’t need to be building a Single Page App either.

A Case for Progressive Web Applications in 2017

If your company is or is planning on doing business in emerging markets, architecting your web applications for performance through progressive enhancements is one easy way to drastically improve accessibility, retention, and user experience.

This article uses “progressive enhancement” and “progressive web app” interchangeably, which would be true in an ideal world. This is the first of a three part series, and it sounds like it will indeed document how to take an existing site and enhance it into a progressive web app—a strategy I much prefer to creating a separate silo that only works for a subset of devices (the app-shell model being pushed by Google).

Retrofit Your Website as a Progressive Web App — SitePoint

Turning your existing website into a progressive web “app”—a far more appealing prospect than trying to create an entirely new app-shell architecture:

…they are an enhancement of your existing website which should take no longer than a few hours and have no negative effect on unsupported browsers.
