Web Components: The Long Game – Infrequently Noted

One of the things we’d hoped to enable via Web Components was a return to ctrl-r web development. At some level of complexity and scale we all need tools to help cope with code size, application structure, and more. But the tender, loving maintainance of babel and webpack and NPM configurations that represents a huge part of “front end development” today seems…punitive. None of this should be necessary when developing one (or a few) components and composing things shouldn’t be this hard. The sophistication of the tools needs to get back to being proportional with the complexity of the problem at hand.

I completely agree with Alex here. But that’s also why I was surprised and disheartened when I linked to Monica’s excellent introduction to web components that a package manager seemed to be a minimum requirement.

Killing Old Service Workers for the Greater Good – Hackages Blog

Ooh, this is a tricky scenario. If you decide to redirect all URLs (from, say, a www subdomain to no subdomain) and you have a service worker running, you’re going to have a bad time. But there’s a solution here to get the service worker to remove itself.

The server-side specifics are for NGINX but this is also doable with Apache.

Chrome to force .dev domains to HTTPS via preloaded HSTS

Well, I guess it’s time to change all my locally-hosted sites from .dev domains to .test. Thanks, Google.

Refraction Networking

This looks like an interesting network-level approach to routing around the censorship of internet-hostile governments like China, Turkey, Australia, and the UK.

Rather than trying to hide individual proxies from censors, refraction brings proxy functionality to the core of the network, through partnership with ISPs and other network operators. This makes censorship much more costly, because it prevents censors from selectively blocking only those servers used to provide Internet freedom. Instead, whole networks outside the censored country provide Internet freedom to users—and any encrypted data exchange between a censored nation’s Internet and a participating friendly network can become a conduit for the free flow of information.

Shadow DOM: fast and encapsulated styles – Monica Dinculescu

Monica explains how Shadow DOM could be the perfect answer for scoping CSS:

We didn’t have style encapsulation, so we started naming things “the right way” with BEM, so that we didn’t accidentally stomp over each other’s styles. We wanted to be able to author CSS from inside a JavaScript component, so we started using CSS-in-JS. We needed all these tools, because “the platform” (read: the browsers that be) wasn’t there, and building these tools showed that there was a need to move forward. For style encapsulation, Shadow DOM is the platform moving forward.

Although, in a way, Shadow DOM is also another flavour of CSS-in-JS:

Before you complain that using a Shadow DOM and Web Components means that it absolutely requires JavaScript: this is true.

(Now More Than Ever) You Might Not Need jQuery | CSS-Tricks

Thanks to jQuery, you probably don’t need jQuery. Just look at all these methods that started life in jQuery, that are now part of the standardised DOM API:

  • remove()
  • prepend()
  • before()
  • replaceWith()
  • closest()

A great short talk by Tim. It’s about performance, but so much more too.

The story of stolen Slovak national Top Level Domain .SK

I’ve heard of people having their domain names hijacked before, but this is the first time I’ve heard of an entire top level domain being nicked.

prettydiff/wisdom: Building better developers by specifying criteria of success

I frequently see web developers struggling to become better, but without a path or any indication of clear direction. This repository is an attempt to sharing my experiences, and any contributions, that can help provide such a direction.

It’s broken down into four parts:

I don’t necessarily agree with everything here (and I really don’t like the “rockstar” labelling), but that’s okay:

Anything written here is open to debate and challenges are encouraged.

Phishing with Unicode Domains - Xudong Zheng

Domains registered with punycode names (and then given TLS certificates) are worryingly indistinguishable from their ASCII counterparts.

Understanding the Critical Rendering Path

A nice and clear description of how browsers parse and render web pages.

Hey designers, if you only know one thing about JavaScript, this is what I would recommend | CSS-Tricks

This is a really great short explanation by Chris. I think it shows that the really power of JavaScript in the browser isn’t so much the language itself, but the DOM—the glue that ties the JavaScript to the HTML.

It reminds me of the old jQuery philosophy: find something and do stuff to it.

Mutating the active element - ally.js

Rodney has done some great research into how different browsers respond to a focusable element becoming inactive (by being made disabled, hidden, or removed).

Shadow DOM v1: self-contained web components | Web Fundamentals - Google Developers

An in-depth look at the current Shadow DOM spec. It’s well-written but I don’t think this will really click with me until I start playing around with it for myself.

It’s good to see that the examples have some thought given to fallback content.

The History of the URL: Domain, Protocol, and Port - Eager Blog

From the ARPANET to the internet, this is a great history of the Domain Name System:

Root DNS servers operate in safes, inside locked cages. A clock sits on the safe to ensure the camera feed hasn’t been looped. Particularly given how slow DNSSEC implementation has been, an attack on one of those servers could allow an attacker to redirect all of the Internet traffic for a portion of Internet users. This, of course, makes for the most fantastic heist movie to have never been made.

Persistent Domains by Tim Berners-Lee

This sixteen year old cool URI has not changed. I think this idea of domains entering an archive state is worth pursuing.

Also, I love the science fictional footnote “Note for readers after 2100”.

Democratize the Internet Now! | New Republic

It is a sad and beautiful world wide web:

The technology that let people make web sites never went away. You can still set up a site as if it were 1995. But culture changes, as do expectations. It takes a certain set of skills to create your own web site, populate it with cool stuff, set up a web server, and publish your own cool-stuff web pages. I would argue that those skills should be a basic part of living in a transparent and open culture where individuals are able to communicate on an equal field of play. Some fellow nerds would argue the same. But most everyone else, statistically, just uses Facebook and plays along.

Paul Ford shines a light on the solution:

Standing against this tide of centralization is the indie web movement. Perhaps “movement” is too strong—it’s more an aesthetic of independence and decentralization. The IndieWebCamp web page states: “When you post something on the web, it should belong to you, not a corporation.” You should own your information and profit from it. You should have your own servers. Your destiny, which you signed over to Facebook in order to avoid learning a few lines of code, would once again be your own.

Beautiful, beautiful writing:

We could still live in that decentralized world, if we wanted to. Despite the rise of the all-seeing database, the core of the internet remains profoundly open. I can host it from my apartment, on a machine that costs $35. You can link to me from your site. Just the two of us. This is an age of great enterprise, no time to think small. Yet whatever enormous explosion tears through our digital world next will come from exactly that: an individual recognizing the potential of the small, where others see only scale.
