3D NetMeeting world
Each one of us has experienced the benefits of hosting a meeting through online visualization tools. Such online providers as NetMeeting gave regular users a more flexible way to share information over the internet.
Now with the ever growing demand for richer environment Intel is introducing a concept of meeting online in a 3D environment.
The ScienceSim will give users the capability to build their own virtual worlds. The possibilities are endless.
ScienceSim provides the basic building blocks (client viewers, installation utilities, management tools, etc.), and new technologies that enable broader interoperability through content sharing. Interested people can quickly bring up their own worlds on their own systems and experiment with creating 3D worlds of their own.” What’s interesting about this project is the amount of open source used and yet the compatibility with Second Life.

Google & Yahoo are ready to search Flash files
It is about time someone in Adobe stood up and fixed the oldest disadvantage in Flash. Finally, Google and Yahoo caches will be able to adequately parse the contents of SWF Flash files and retrieving text values from graphically advanced objects.
Developers such as my self who are boggled by Flash capabilities and at the same time annoyed by the disadvantages of setting up a highly functional webpage only to face the inevitability of fighting browsers and client settings were forced to find other means of providing the infamous crawlers with the content that could not be retrieved from the compiled Flash executable.
Here are some facts that one might find interesting:
1. The new improvement can be applied to every version of the SWF format. [Both old and new].
2. Developers do not need to modify their existent project to make the content more searchable, the information will be available at the get go.
3. Google has already began the rollout process of the new searchable SWF capability.
4. At the moment the searching capabilities only affects the text base interior of the SWF file. Currently there is no logic that focuses on the graphical [images] aspect of the infrastructure.
Overall the new changes spell faster, better search results when it comes to working with flash. The long despised draw back can finally be forgotten and a new age of vibrant high dimensional applications is waiting to make their mark on the web.

Workaround for: “Click to activate and use this control” IE problem.
Those of you who have been found of putting up interesting controls on your web pages might have come across the ‘Click to activate and use this control’ bug that occurs in Internet explorer. If you do some searching you will find a lot of posts that require upgrade and an installation of a patch. Having explored the problem my self I offer you an alternative solution:
- Create a javascript function that is initiated when the page is loaded ‘onload’ event.
- Create a tag with a particular id somewhere on your page [lets say "fuzzy_object" for a sake of an argument].
- In your javascript function create a single string containing the specifications of your object [in my case it was an swf file].
- Perform the following: document.getElementById(‘fuzzy_object’).innerHTML = concatinated_string.
This is a tad generic but it should work. If not just let me know and I’ll post a more detailed solution.

Cyrilic integration of Flex and PHP
A recent project involved integration between a PHP content management tool like Joomla and Adobe Flex 2. I wrote a PHP script that parsed a MySQL database creating an XML structure that was then picked up by a HTTPService in a Flex application.
The information in the database was stored in Cyrillic format, hence when ever I was loading the data in to the SWF compiled file the end result was a collection of garbage data. Setting the actuall HTML to Windows-1251 encoding did not help the situation.
My following approach was to locate a native functionality within the Flex architecture to mediate the situation. Unforchunately I wasn’t successful in aquiring sattisfying examples to solve the problem. For that matter it became sadly obvious that I haven’t seen any flash pages using non/english alphabet [either I haven't been checking international sites that much or Adobe Flex isn't widely used overseas] .
My third approach was to look at the actual php code that was generating the XML structure. I’ve discovered a useful function mb_convert_encoding that eventually solved my problems. Using a simple snippet of code:
mb_convert_encoding($string_to_convert,'UTF-8','Windows-1251');
I was able to convert the data from UTF-8 in to Windows-1251 which allowed me to display the desired Cyrillic characters.

Hacking CSS
There’s quite a few links out there that talk about the different methods of hacking IE and Firefox along with many other browsers.
Having been developing in Adobe Flex for the past while I’ve been ignoring the CSS issue but in my latest project I had to face the beast. My goal was to find a way in which I can block particular tags in both IE and in Firefox. so here’s what I found after doing some research.
For a page where you have an internal <div id=”pathway_text_inner”> the following will be ignored in Firefox:
#pathway_text_inner{
_width: 900px;
_padding-left: 10px;
_padding-top: 7px;
}
Pretty much anything that is preceded by an underscore is ignored in Firefox.
Similarly the following is ignored in IE7.
*:lang(en) #pathway_text_inner{
padding-left: 10px;
padding-top: 10px;
height: 20px;
overflow: hidden;
width: 890px;
}
where <body lang=”en”> .
I know there’s been quite a bit written about the subject but I couldn’t find the exact answer from the first Google search that I performed. Hence this post.
Cheers.

Getting your web optimization hat on.
A friend of mine asked me a question: “Do you know anything about Search Engine Optimization?”.
Sadly I had to respond that ‘No, not really’. Neadless to say, eager to learn more about the subject and knowing that soon in the near future I would have to look in to the subject my self I started Googling.
Without long I came across two interesting articles, ‘A modern approach to Flash SEO‘ – related to designing website in Flash and dealing with the known problem that Google might/might-not parse .swf files when crawling through web pages. A second article dealt with an example of how when developing a website the QA rarely takes in to account the prespective of a search engine web-crawler to which I suggest examining the ‘SEO Tools – Spider Simulator‘ article.
Thats it for now, stay tuned for more info.
