mod_pagespeed is an open-source Apache module that automatically optimizes web pages and resources on them. It does this by rewriting the resources using filters that implement web performance best practices. Webmasters and web developers can use mod_pagespeed to improve the performance of their web pages when serving content with the Apache HTTP Server.

mod_pagespeed includes several filter that optimize JavaScript, HTML and CSS stylesheets. It also includes filters for optimizing JPEG and PNG images. The filters are based on a set of best practices known to enhance web page performance. Webmasters who set up mod_pagespeed in addition to configuring proper caching and compression on their Apache distribution should expect to see an improvement in the loading time of the pages on their websites.

jQuery has changed the way we write Javascript by abstracting out much of the painful cross-browser implementation details that used to plague developers, but to use it correctly still requires a little knowledge about what’s going on under the hood. In this post we’ll take a good look at jQuery’s selectors and how to use them efficiently. I’ll also talk briefly about DOM manipulation and event handlers.

Mako is a template library written in Python.

It provides a familiar, non-XML syntax which compiles into Python modules for maximum performance.

Mako's syntax and API borrows from the best ideas of many others, including Django templates, Cheetah, Myghty, and Genshi.

Conceptually, Mako is an embedded Python (i.e. Python Server Page) language, which refines the familiar ideas of componentized layout and inheritance to produce one of the most straightforward and flexible models available, while also maintaining close ties to Python calling and scoping semantics. Mako is used by the python.org website as the basis for their site build system (README), as well as by reddit.com for their newly launched beta site.

It is the default template language included with the Pylons web framework.

Underscore is a utility-belt library for JavaScript that provides a lot of the functional programming support that you would expect in Prototype.js

(or Ruby), but without extending any of the built-in JavaScript objects. It's the tie to go along with jQuery's tux.

Underscore provides 60-odd functions that support both the usual functional suspects: map, select, invoke — as well as more specialized helpers: function binding, javascript templating, deep equality testing, and so on. It delegates to built-in functions, if present, so modern browsers will use the native implementations of forEach, map, reduce, filter, every, some and indexOf.

This document is an introductory course on Unix system programming, with an emphasis on communications between processes. The main novelty of this work is the use of the Objective Caml language, a dialect of the ML language, instead of the C language that is customary in systems programming. This gives an unusual perspective on systems programming and on the ML language.

FancyBox is a tool for displaying images, html content and multi-media in a Mac-style "lightbox" that floats overtop of web page. It was built using the jQuery library. Licensed under both MIT and GPL licenses.

This article is for those who are new to ARIA. You need an understanding of HTML and the potential difficulties that people with disabilities can face using the Web. It is useful to be familiar with some Rich Internet Applications from a user's perspective

After reading this article, you'll understand what ARIA is for, how to integrate it into your sites, and how you can use it now to make even the simplest of sites more accessible.

Video for Everybody is simply a chunk of HTML code that embeds a video into a website using the HTML5 <video> element, falling back to Flash automatically, without the use of JavaScript or browser-sniffing. It therefore works in RSS readers (no JavaScript), on the iPhone / iPad (don’t support Flash) and on many, many browsers and platforms.
