How to reset canvas in HTML5
The excellent “Dive Into HTML5″ online tutorial by Mark Pilgrim mentions that to reset a canvas (= clear all its contents), all you need to do is set its width. It even says that you can set the width to be the same as the current width and gives the example below

HTML5 sample code for drag ‘n’ drop and many more features
If you are the type of programmer who learns by reading code and hacking it, head over to HTML5 Studio, a new area on Google’s HTML5 website with sample code provided for Geolocation, Columns, Drag & Drop features and many more.
I quote from the site
Peek around, look under the covers at the source, and feel free to reuse the code in your own applications and sites.
HTML5 rocks indeed
I’ve just checked out the HTML5 presentation at HTML5 Rocks, it’s pretty impressive.
Of course, it’s a catch 22 situation: the more HTML5 compliant your browser is, the more you’ll enjoy the presentation (which encompasses HTML5, CSS3 and the new JS APIs). They should do a video of it showing what it should look like so people with older browsers might find out about it and decide to upgrade their browsers 
Top 5 reasons to ditch Flash and embrace HTML5/CSS3 now
1. HTML5 & CSS3 standards are open so you don’t rely on the whims of one company.
2. Big websites like YouTube are already getting into the game (check out YouTube HTML5 Video Player) so you can bet the demand for HTML5 skills is going to rise.
3. You don’t need to buy a proprietary software so you can easily code HTML5 & CSS3 on your laptop, your roommate’s computer and your mum’s computer.
4. The iPad doesn’t support Flash. While you might disagree with Apple’s choice, this is the choice they made and the iPad is going to foster a new range of interactive websites – all those made with HTML5 and CSS3. Do you want in or do you want out?
5. The current big battle is Google vs Apple (Microsoft seems to have lost the race). They are both committed to HTML5 so even if one wins and the other one gets swallowed up, HTML5 will still be supported.

I must…
… learn Scala.
… learn how to use the command shell in Ubuntu.
… refresh my Perl knowledge.
… investigate HTML5.
Because
… I want to learn a multi-paradigm language and Scala can integrate with Java, a language I already use.
… I need to know my programming tools and not just rely on Eclipse.
… I want to write some quick text manipulating scripts to help with producing content for a couple of apps I’m working on.
… I was blown away by the HTML5 demos at Google I/O (No, I didn’t attend, I watched it on YouTube).
