Resumable.js is a JavaScript library providing multiple simultaneous, stable and resumable uploads via the HTML5 File API. The library is designed to introduce fault-tolerance into the upload of large files through HTTP. This is done by splitting each files into small chunks; whenever the upload of a chunk fails, uploading is retried until the procedure completes.

Resumable.js allows uploads to automatically resume uploading after a network connection is lost either locally or to the server. Additionally, it allows for users to pause and resume uploads without loosing state. Currently, it is limited to Firefox 4+ and Chrome 11+.

Requirements: HTML5 and JavaScript Framework

Font.js is a Powerful Font Toolkit for JavaScript. It gives you font loading events using a technique perfected in Mozilla’s pdf.js project, metrics information, and a better version of the canvas element’s measureText method with additional information such as height, bounding box, and leading.

Font.js works by downloading the font data with an AJAX request, parsing out some metadata to determine that it is indeed a valid font file and to pull out the metrics information. Then it inserts an @font-face rule into the page.

Whilst we see, read and hear a lot about the new semantic elements in HTML5 we arguably hear far less about the application programming interfaces (APIs) that make up a large part of the specification itself.

In some cases the APIs have been around and implemented for a while, but they’ve never been documented; something which HTML5 has set out to change.

.Net Magazine has published an article: The developer’s guide to the HTML5 APIs, which we’re not going to look at code but instead we’ll focus on describing the APIs, their purpose and progress. So that you will be in the right direction to find out more.

Many of us start every HTML project with the same set of HTML and CSS files. We’ve been using these files for a long time. Now that modern browsers are starting to support some of the really useful parts of HTML5 and CSS3, it’s time for our best practices to catch up.

HTML5 Reset is a simple set of best practices to get web projects off on the right foot. It includes A style sheet designed to strip initial files from browsers, Analytics and jQuery snippets in place, Meta tags ready for population, Empty mobile and print style sheets, IE-specific classes for simple CSS-targeting, iPhone/iPad/iTouch icon snippets and lots of other keen stuff.
