I’ve worked with Flash for several years and have always been slightly dissatisfied with the markup needed to embed a movie in web pages. When I recently published a site in XHTML, my dissatisfaction with the markup grew as I realized that it simply wasn’t valid in this context and was bloating my pages to unacceptable levels. A leaner, standards-compliant method of embedding Flash movies was called for.

pyquery allows you to make jquery queries on xml documents. The API is as much as possible the similar to jquery. pyquery uses lxml for fast xml and html manipulation.

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.

Guacamole is an HTML5 + JavaScript (AJAX) viewer for VNC, which makes use of a server-side proxy written in Java. The current version is almost as responsive as native VNC and should work in any browser supporting the HTML5 canvas tag.

Guacamole provides access to your VNC server through a proxy written in Java. The server-side half of Guacamole thus requres a servlet container like Apache Tomcat, while the client-side requires nothing more than a web browser supporting HTML5 and AJAX.

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

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.

Usage: Click the "Add Fonts" button, check the agreement and download your fonts. If you need more fine-grain control, choose the Expert option.

HTML5 Boilerplate is the professional badass's base HTML/CSS/JS template for a fast, robust and future-proof site.

After more than two years in iterative development, you get the best of the best practices baked in: cross-browser normalization, performance optimizations, even optional features like cross-domain ajax and flash. A starter apache .htaccess config file hooks you the eff up with caching rules and preps your site to serve HTML5 video, use @font-face, and get your gzip zipple on.

Boilerplate is not a framework, nor does it prescribe any philosophy of development, it's just got some tricks to get your project off the ground quickly and right-footed.

Like a lot of developers, we start every HTML project with the same set of HTML and CSS templates. We've been using these files for a long time and we've progressively added bits and pieces to them as our own personal best practices have evolved.

Now that modern browsers are starting to support some of the really useful parts of HTML5 and CSS3, it's time for an update, and we thought we'd put it out there for everyone to use. By no means do we see this as the end-all and beat-all, but we think it's a fairly good starting place that anyone can take and make their own.

Designing an HTML email that renders consistently across the major email clients can be very time consuming. Support for even simple CSS varies considerably between clients, and even different versions of the same client.

We’ve put together this guide to save you the time and frustration of figuring it out for yourself. With 23 different email clients tested, we cover all the popular applications across desktop, web and mobile email.
