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+.

Jef Vlamings had an idea to build a calendar app called LiveCal, which was supposed to become a platform where you could share calendars. The whole idea was that calendars would become something you subscribe to. Due to the complexity of the idea and the lack of knowledge, the project never really took off.

However, he made a CSS3 calendar with some jQuery animation while he was working on the project. And then he has shared a nice tutorial on How to Create A Clean Calendar in CSS3 & jQuery.
