On dependency | RobWeychert.com V7

I’m very selective about how I depend on other people’s work in my personal projects. Here are the factors I consider when evaluating dependencies.

  • Complexity How complex is it, who absorbs the cost of that complexity, and is that acceptable?
  • Comprehensibility Do I understand how it works, and if not, does that matter?
  • Reliability How consistently and for how long can I expect it to work?

I really like Rob’s approach to choosing a particular kind of dependency when working on the web:

When I’m making things, that’s how I prefer to depend on others and have them depend on me: by sharing strong, simple ideas as a collective, and recombining them in novel ways with rigorous specificity as individuals.

Hobbies for the hell of it | Brad Frost

We should celebrate our hobbies for the joy-giving activities they are, and recognize that they don’t need to become anything bigger than that. And of course that’s not to say they those hobbies can’t turn into something bigger — it’s incredible when your passions and your occupation overlap — but it should be because you want to rather than that you feel pressured to. Not every activity you do needs to become a big official thing.

Why Progressive Web Apps Are The Future of Mobile Web [2019 Research]

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.

The Simplest Way to Load CSS Asynchronously | Filament Group, Inc.

Scott re-examines the browser support for loading everything-but-the-critical-CSS asynchronously and finds that it might now be as straightforward as this one declaration:

<link rel="stylesheet" href="/path/to/my.css" media="print" onload="this.media='all'">

I love the fact the Filament Group are actively looking at how deprecate their loadCSS polyfill—exactly the right attitude for polyfills in general.

How Ireland became Europe’s data watchdog - BBC News

The coming GDPR storm:

Ireland’s Data Protection Commissioner, Helen Dixon, is expected to circulate her decisions on some cases by July or August, with final rulings made by the end of the year.

(That’s my sister-in-law, that is.)

Voxxed Thessaloniki 2018 - Opening Keynote - Taking Back The Web - YouTube

Here’s the talk I gave recently about indie web building blocks.

There’s fifteen minutes of Q&A starting around the 35 minute mark. People asked some great questions!

How to get on the #indieweb!

As well as graciously hosting Indie Web Camp Berlin on the weekend at Mozilla’s offices, Yulia has also drawn this super-cute comic.

The Font Loading Checklist—zachleat.com

This checklist came in very handy during a performance-related workshop I was running today (I may have said the sentence “Always ask yourself What Would Zach Do?”).

  1. Start Important Font Downloads Earlier (Start a Web Font load)
  2. Prioritize Readable Text (Behavior while a Web Font is loading)
  3. Make Fonts Smaller (Reduce Web Font load time)
  4. Reduce Movement during Page Load (Behavior after a Web Font has loaded)

The first two are really straightforward to implement (with rel="preload" and font-display). The second two take more work (with subsetting and the font loading API).

“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.

Ways to think about machine learning — Benedict Evans

This strikes me as a sensible way of thinking about machine learning: it’s like when we got relational databases—suddenly we could do more, quicker, and easier …but it doesn’t require us to treat the technology like it’s magic.

An important parallel here is that though relational databases had economy of scale effects, there were limited network or ‘winner takes all’ effects. The database being used by company A doesn’t get better if company B buys the same database software from the same vendor: Safeway’s database doesn’t get better if Caterpillar buys the same one. Much the same actually applies to machine learning: machine learning is all about data, but data is highly specific to particular applications. More handwriting data will make a handwriting recognizer better, and more gas turbine data will make a system that predicts failures in gas turbines better, but the one doesn’t help with the other. Data isn’t fungible.

New Privacy Rules Could Make This Woman One of Tech’s Most Important Regulators - The New York Times

It’s kind of surreal to see a profile in the New York Times of my sister-in-law. Then again, she is Ireland’s data protection commissioner, and what with Facebook, Twitter, and Google all being based in Ireland, and with GDPR looming, her work is more important than ever.

By the way, this article has 26 tracking scripts. I don’t recall providing consent for any of them.

Hack for the craic: David McKeown on making hackathons fun for everyone

A great write-up of Science Hack Day Dublin—the 6th iteration is coming up next month.

What struck me about this hackathon is that the only end goal is for people to have a bit of fun and make stuff. There’s no flashy big-ticket prize and no commercial agenda. They’re not looking for start-up pitches or scalable business plans, and there’s no Dragons’ Den interrogation. Just good old-fashioned, high-tech making and mingling.
