Copy this into the console of any web page that is interactive and doesn't

I have found this interesting for debugging, but also fun to hear web pages
render like UIs do in movies.

The BBC has a server-side image service which provides developers with multiple sized versions of any image they request. It works in a similar fashion to http://placehold.it/ but it also handles the image ratios returned (where as placehold.it doesn't).

The original BBC News process (and my re-working of the script) follows roughly these steps...

• Create new instance of ImageEnhancer
• Change any divs within the page (which have a class of delayed-image-load) into a transparent GIF using a Base64 encoded string.
  • We set the width & height HTML attributes of the image to the required size
  • We know what size the image needs to be because each div has custom data-attr set server-side to the size of the image
  • We then set a class of image-replace onto each newly created transparent image
• We use a 250ms setTimeout to unblock the UI thread and which calls a function resizeImages which enhances the image-replace images so their source is now set to a URL whe

Lesson's learnt building the Guardian

Below is a collection of my favourite responses I gathered from Guardian engineers when asked the question: What have you learnt starting from scratch and building a mobile-first next generation web platform for the Guardian?

• Work with great people.
• Deploy like crazy. This means the team has to control the infrastructure as well as code.
• Design is not a service. Designers have to sit in the team.
• Infrastructure is intrinsically unreliable. Discard and replace is the robust strategy.
• Use your CDN for HTML too.
• Don't always do as you are told.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
