Another FOSDEM (Free Open Source Developers European Meeting) conference took place in the same location, the Universite Libre de Bruxelles (ULB) in 5-6 February 2011. A lot of participants, really, most of the rooms were full and you had to queue a lot of time in advance in order to find a chair to sit.
As a result I missed some interesting talks. A lot of stands of companies too, of OSS but also of OSH (Open Source Hardware) this year.

As a result I missed some interesting talks. A lot of stands of companies too, of OSS but also of OSH (Open Source Hardware) this year.
Some interesting talks:
- HTML 5 by Robert Nyman and Christian Heilmann
- Practical Go Programming, a new language by Google
- Firefox 4: new features for users and developers
- Scala expressiveness
- State of OpenJDK
A number of insteresting stands, as already mentioned:
HTML 5 introduces a lot of goodies like: autocomplete box, email text field, color and date picker, range controls , search bar, input validation, placeholders, autofocus etc. Its main advantage is that for the first time it standardises Javascript, that means you don't need to write different javascript code for the different browsers.
It introduces a Canvas to draw images, play videos etc.
Since SVG is also a very powerful library for vector graphics, what does Canvas bring more? Well, use Canvas for speed and SVG for interaction.
It provides a lot of methods for interacting with the video, e.g.
Using these methods you can interact with e.g. a Flash video which was a black box up to HTML 4. CSS3 allows you to interact with the video.
While HTML 4 is stateless, HTML 5 is statefull, i.e. it allows you to store session variables to the web storage.

<video controls><
<source src="..." type="video/mp4" media="..."></source><
<video>It provides a lot of methods for interacting with the video, e.g.
load(), canPlayType(type), play(), pause(), stop(), addTrack() // for subtitlesetc.
Using these methods you can interact with e.g. a Flash video which was a black box up to HTML 4. CSS3 allows you to interact with the video.
While HTML 4 is stateless, HTML 5 is statefull, i.e. it allows you to store session variables to the web storage.
sessionStorage.setItem(key, value);
localStorage.setItem(key, value);There is also support for webSQL and indexedDBs but also many TODOs:
- WebWorkers for multi-threaded Javascript
- WebSockets for realtime multi-user interaction
- Audio analysis
- Face detection
- Image generation
- Server side rendering
- Multi-touch interfaces
- Device input support (e.g. cameras)
