Just a quick note to people around here: Opera Software has recently published a new article I wrote:
SVG or Canvas? Choosing between the two. You can also read the article on my server. As usual, thanks go to Chris Mills for reviewing and providing feedback for improvements to the article.
In unrelated news, things are going fine around here. A new web site I've been working on will be released to the
public pretty soon. More cool stuff will come. ;)

I am getting closer to having a Moodle demo ready with PaintWeb integrated. Wednesday I had a very fruitful discussion with my mentor, Martin, on how I should proceed with the implementation
of file saving inside the Moodle data directory. We have come to a conclusion which I am about to implement. More details
For now, I have registered a Moodle Git repository mirror
over at repo.or.cz. I have also registered a Moodle "fork" where I publish my Moodle branches. You can do:
git clone git://repo.or.cz/moodle/mihaisucan.git ~/src/moodle-mihai
git checkout -b mdl19-paintweb origin/mdl19-paintweb
With that, you can easily and quickly get an always up-to-date Moodle 1.9 stable branch with TinyMCE 3 and PaintWeb integrated. You can already play with PaintWeb in Moodle.
If you only want the TinyMCE 3 editor you can do:
git checkout -b mdl19-tinymce3 origin/mdl19-tinymce3
The TinyMCE 3 branch holds Moodle 1.9 stable with the latest TinyMCE 3 integrated. The work I did on this branch is
best explained in a Moodle forum discussion.
When you want to update your branch simply invoke
git pull. Please also check the official documentation
how to use Git.
In related news, Opera Software has published the final part of the article serie I wrote about
keyboard accessibility in Web applications. This article details the cross-browser compatibility layer implementation for keyboard events used by PaintWeb.

The Google Summer of Code midterm evaluations passed without any problems for me, yay!
I have began work on integrating PaintWeb into Moodle. I will integrate my project into the stable Moodle 1.9 branch and into the upcoming Moodle 2.0 release.
Moodle 1.9 has a very old TinyMCE release (version 2.0) which is not used by
default - the even older HTMLArea is still used. Both do not work in Opera and Google Chrome. For this reason Martin Langhoff,
my mentor, and other Moodle community members have worked on patches to switch to the modern TinyMCE 3 editor. A
clean port of TinyMCE 3 to Moodle 1.9 is available on the
The clean port is quite well done, but again, it was "outdated", being from october 2008.
For PaintWeb I took the work Martin did and updated it to the latest Moodle 1.9 stable branch, the latest TinyMCE 3
version, and made additional fixes. One fix was to make the editor show up in Opera, Safari and Chrome, and another
fix was for the script which converts TinyMCE language files to Moodle language files.
PaintWeb integration into Moodle 1.9 will come as a patch on top of the TinyMCE 3 patch. Currently I got PaintWeb
loading fine in TinyMCE, inside Moodle. More work is needed to get file save working. For PaintWeb I did some assorted
fixes for the Makefile, for the overall keyboard accessibility, for multi-language support, and I did improvements to
the TinyMCE plugin.
You can download the updated TinyMCE 3 patch for Moodle 1.9.
The package includes usage instructions.
In other related news, Opera Software has published the second part of the article I wrote about
keyboard accessiblity in Web applications. This article describes the inner workings of the MouseKeys extension for PaintWeb. Make sure you checkout the
updated and improved
source code of the MouseKeys extension in the PaintWeb code tree.
Have fun until the next time!

In the past week there was important progress on PaintWeb. I have
published several wiki pages about PaintWeb on Google Code - this documentation comes as an overview or a guide to the entire codebase and the API reference. You can read about how to integrate PaintWeb into your Web application, how to extend PaintWeb, how to package PaintWeb yourself with the Makefile, and how to use the new TinyMCE plugin.
I have completed a new
TinyMCE plugin which allows you to easily and quickly integrate PaintWeb. This plugin allows users to click an "Edit" button which is
overlayed on top of the editable images. The plugin also includes a context menu item (right-click and choose "Edit image"),
and a toolbar button.
I have published a new demo page which shows the latest TinyMCE and PaintWeb working together. Enjoy!
Moodle integration is currently being planned. I wrote my thoughts and questions in a Moodle Docs wiki page about the paint tool integration.
Last, but not least, for the purpose of tracking progress, I have attached a packaged PaintWeb snapshot to the Moodle tracker issue associated with my project.
Olli Savolainen has created some very good mockups as proposals to improve the PaintWeb user interface. His feedback is very much appreciated, and I really hope to get to implement his suggestions as soon as possible.
On a related note, for those interested on
how PaintWeb implements keyboard shortcuts, Opera Software has just published the first part of a series of articles I wrote on this topic. More articles will
be published soon at the Opera Developer community site.
Have fun testing PaintWeb and reading articles about it. Don't forget that I am always looking forward for feedback!

I have great news this time! I have applied to work for the
Moodle project over the summer within the Google Summer of Code program. My project proposal has been accepted. This means that
over the summer I will be working on integrating the PaintWeb project into
Moodle. Part of this work will also include a complete code reorganization and several important improvements.
Locally I have already started working towards code reorganization and a complete rework of the keyboard shortcuts
support inside PaintWeb is ready. This work will become public very soon.
I am really glad to be working with one of the best open-source educational software. The Moodle community has been
very nice and they welcomed me warmly. Congratulations to every student who has been accepted this year!
On a related note, Opera Software has published a tutorial I wrote about how you can start developing your own paint tool. The code presented is strongly based on my work for PaintWeb. Another new tutorial is now being prepared for
Best luck to everybody and stay tuned for more!

Hello everyone and a happy new year!
Opera Software has just published my third tutorial: HTML 5 canvas - the basics. Hopefully, I will have more tutorials coming about canvas and other Web technologies.
With this occasion I have updated my site and I added a new

Today Opera Software has released a new site: The Opera Developer community site.
The purpose is great, and I like major web browsers having their own developer community sites.
As the title of this post announces ... the site already had published my first tutorial :). If you've read my
previous blog posts, it's not a big surprise my first tutorial is about voice interactivity. Currently, very few know
about VoiceXML, and there are very few tutorials. Most of them reach only the level of "Hello world". Therefore, my
tutorial goes much further, by actually telling you how to put voice to use in your site. I didn't write yet-another
Go ahead and read the tutorial from dev.opera or from
my own server (mirror).
Thanks very much to TarquinWJ and Jax. The tutorial has reached the level of maturity you are seeing thanks to both of them. :)
Any suggestions or comments are welcome.
