Domeo and Utopia integration through Annotopia

Here is a very recent demo of annotation created on a HTML document through Domeo and then seen on the correspondent PDF with the Utopia PDF viewer. All through Open Annotation and Annotopia.

Thanks to Steve Pettifer and Dave Thorne (for the Utopia plugin development); Thomas Wilkins for OAuth implementation in Annotopia. Annotopia is currently architected and developed by me.

Domeo v2 working much faster on Firefox then Chrome

Since a week now, I am deeply involved in developing the v.2 of the Domeo annotation tool. Domeo is a combination of GWT (Google Web Toolkit) and JavaScript. I've been mainly working on the infrastructure and, initially, as it is not much UI work, I was testing only on Chrome (16.0.912.75). Sadly, I've  noticed several times that my code was not running fast enough and I started to study alternative ways of performing various tasks.

Then, out of curiosity, I ran the same tests on Firefox and surprise... what was running slow on Chrome was running almost without any latency in FF (6.0.2).

The test consists in 18 steps and each of them is adding the same amount of complexity. Looking at the above figure (milliseconds on the Y-axis) you will easily detect what I am talking about. The difference seems way too big.
