Need to understand the tradeoffs:

• maintainability: manual sprites,
• agility: given caching when can you release new features

Provide benefits without manually keeping track of what needs to be consolidated and compressed.

What are the trade-offs with the full site.

Is there a trivial way to approach?

Uses a md5 sum for the stylesheets in the page.

How can one whitelist the files.

How about full site? Aren't there global, app, and page specific stylesheets?

Is the core audience those who don't have the resources to apply logic to resource consolidation?

Includes parsers, v8, zlib for Apache.

Used MSIE8 with Web Page Test.

Tests were done over 28 sites showed a 25% re

Parsing the website is additional overhead and will slow the site down.

1. Look at the headers to show site performance
2. Review with Web Page Test

Check http://androidacademy.com waterfall.

Reduced the overall number of objects by inlining some images and consolidating resources.

The most significant improvement was from the repeat view.

Is it possible that mod_pagespeed on wal.sh is something that is changing the performance profile.

Repeat view waterfull shows the benefit of the md5 sums.

Base run against a page repated with both values set. What custom work would need to be done to define what consistitues site page.

Site or page benefits

Consolidated sprite format:

<img src='group.webp#john'/>

Look at the way that Opera proxies content to optimize the content.

This is a proxy server for improving the performance.

Test could be run where we just run against a local instance.

• Gomez Recorder

• Increased round trip time
• Bandwidth

Need to remember that mobile devices aren't connected all the time -> decreased bandwidth and increased latency.

3g networks will require 3s for getting the intial DNS request while the device requests a channel.

Key issue with how the pages load.

Less mememory > amount of required garbage collection.

• Small functional
• 1995: First implementation with DOM0
• 1999: ECMAScript v. 3

The competition now generally comes down to performance rather than new language features.

Reads top to bottom.

All objects, most are mutable.

Functions are first-class.

Can hide data in functions.

Delegation and not classes.

Inverts the relationships generally considered with other OO languages by virture of closures.

Objects carry behavior rather than behavior operating on objects.

closures, first-class functions, tools for passing functions (forEach).

> [] instanceof Object true > {} instanceof Object true > (function(){}) instanceof Object true

Integer indexing is just a form of converting an index into a string then check the property.

Just use this bound to passed formal parameters.

function Behavior(config) { }

Pass in the configuration rather than using the new operator.

Alternative:

function bindBehavior(config) { }

• Requires use of traits for general composition of class-like behavior
• Limited since it's just semantics but is per-library

"Good when you can do it, not when everyone can do it."

Self-executing anonymous functions.

See goog.require and goog.provides as dependency management.

module, require, imports…

Want to be able to have the semantics of the language support inheritance.

Describe the new language feature in terms of the old language but maps to patters of what is implemented.

Seen if one is doing boilerplate.

Example: variable arguments support requires slice() on arguments after 2.

"Language evolution isn't a straight-line thing."

String.prototype.printf() = function(format='…', params) { console.log(params[0]); }

"My string".printf('…', 'Arguments')

Traceur has

• Classes, Traints
• Harmony modules
• Async
• Destructuring assigments (?)
• Scoped object extensions

Implement just against V8 for fast-moving support:

• Chrome Web Store
• Crome Frame
• Mobile

Deferreds and promises currently have some error handling.

Use weight or async keywords.

"Macros they way you would want them aren't possible with JavaScript."

"Not hopeful for type systems…"

If you get impedence mismatches between the source language and JavaScript.

Tom Bancoffs traits(?)

Use the console and node rather than trying to use the UI.

Use strict inside of all functions.

Can get storage quota. Looking at implementing in Chrome 13.

New StorageInfo interface allows temporary and persistent storage.

• queryUsage()
• requestQuota()

Just ongoing work.

3D initial CSS support is in Chrome 12.

Platform changes needed when building very large applications.

Create expectations for mobile performance for the mobile solution.

What is the baseline for how pages get loaded.

• Should see initial manifest load; shows that the state
• Should have a set of core rules to evaluate the time of the load
