Network Information API

It looks like this is landing in Chrome. The navigator.connection.type property will allow us to progressively enhance based on connection type:

A web application that makes use of a service worker to cache resources during installation might have different bundles of assets that it might cache: a list of crucial assets that are cached unconditionally, and a bundle of larger, optional assets that are only cached ahead of time when navigator.connection.type is 'ethernet' or 'wifi'.

There are potential security issues around fingerprinting that are addressed in this document.

LA Times and ads | Nelson’s log

A lot has been written about the future of journalism, the importance of businesses like the LA Times being profitable as a way to protect American democracy. I agree with that in theory. But this sort of incompetence and contempt for readers makes me completely uninterested in helping their business.

Like Craig says…

World Wide Web, Not Wealthy Western Web (Part 1) – Smashing Magazine

Bruce widens our horizons with this in-depth look at where and how people are accessing the web around the world.

In this article, we’ve explored where the next 4 billion connected people will come from, as well as some of the innovations that the standards community has made to better serve them. In the next part, we’ll look at some of the demand-side problems that prevent people from accessing the web easily and what can be done to overcome them.

Service Workers: Save your User’s Data using the Save-Data Header | Dean Hume

I hadn’t heard of the save-data header. This article shows how you can use a Service Worker to sniff for it and serve up smaller assets, but I’m guessing you could also sniff for it from the server.

The Nor » Low Latency

Like an Enid Blyton adventure for the 21st century, James goes out into the country and explores the networks of microwave transmitters enabling high-frequency trading.

If you think that London’s skyscraper boom is impressive – the Shard, the Walkie-Talkie, the Cheesegrater, the Gherkin – go to Slough. It is not height that matters, but bandwidth.

Page Weight Matters | Chris Zacharias

An excellent tale of performance optimisation …complete with a coda on looking behind the numbers when it comes to analytics data.

Latency: The New Web Performance Bottleneck - igvita.com

This is just wonderful! It combines almost all of my recent obsessions into one unified post: website performance (particularly on mobile) and the locations of undersea cables. The interactive map is the icing on the cake.

bandwidth (tecznotes)

Mike compares the bandwidth usage of the sites he most frequently visits. The results are grim.

The worst sins of the Flash years are coming back with a vengeance, in the form of CSS Frameworks and the magic dollar sign. There has seriously got to be a better way to do this.

this, is boomerang

This code could be useful in determining a user’s bandwidth.

The Mobile context

Yes! Yes! Yes! Mark nails it: just because someone visits a site with a certain kind of device doesn’t mean you can make assumptions about their intentions.

  • Mobile != low download speed
  • Context != intent

Bruce Lawson’s personal site : Is mobile web development compatible with the One Web?

An excellent write-up by Bruce of a talk he gave at the Betavine birthday party. Down with .mobi! One Web FTW!

Blaby Conservative Future: Subscription Rate

This blogging Tory MP is stealing someone's bandwidth for the photo in this post. Said photo has been subtly altered. Hilarity ensues in the comments.

Newsvine - Hacking John McCain

John McCain stole Mike Davidson's bandwidth. This sounds like a job for .htaccessman.
