Interconnecting Flex modules
0Adobe Flex 3 has a very interesting component : LocalConnection. The idea behind is that the modules (which runs on client side) might change some data. The exchanged data is not limited at all to simple forms, but can be from a simple String to a XML or Arrays.
Few things must be known from the start, but as any technology, only after you learn it everything becomes easy.
- First of all, the communication can be restrained to a certain domain, let’s say by example www.radupoenaru.com .
- You can’t have bidirectional communication from a single LocalConnection. One module acts as a server and another one as a client.
- Server module opens a connection to which client connects. If the client loads but the server don’t, then an error occurs in client module.
- Be very careful to the name of the procedure called by server – should be the same in server as in client module. (more…)
Tweet your ideas through JavaScript
0Do you have a website and would like to post your tweets from it ? Or maybe you want to create a widget that posts weather on your twitter account?
I encountered this situation and overcome it with the following script. It is pretty simple, but beware that JavaScript is run on CLIENT side, thus any code must be sent in clear.Since it is needed that you provide a password for your account, would not be so wise to put it in clear.
NOTE: I use it for a Vista sidebar gadget, so only IE code is below. For FireFox or Opera the modifications are trivial. (more…)
Flex 3 debugging && Nod32 != Love
0While working at Fraunhofer FIT, I had few small projects to develop internal modules for extending the interaction between researchers. The technologies were set from the start to Flex 3 and ActionScript.
As starter in Flex, but not ActionScript, I was quite anxious to begin coding in this interesting tool. But after I created my new Workspace (seems that now everyone creates its own paradigm for Project) and wrote some code, I hit a wall: the Flex IDE debugger interface raised an error that he couldn’t connect to the Flash debugger:
Choosing hosting for WordPress
2
One of the most important questions in launching a website is the hosting.
When moving to private hosting, I realized that I don’t need all features of the premium hosting plans, just a reliable hosting with basic tools to help me do my tasks easier, without too much investment. Also I wanted to continue using WordPress and reuse the content already created in my old website.
The requirements of WordPress from my hosting were pretty small:
- PHP 4.3 or greater
- MySQL 4.0 or greater
- The mod_rewrite Apache module
- What they don’t mention on website Required WordPress space: At least 10 Mbytes of space on server
URL Rewrite = mod_rewrite
0SEO tools and mod_rewrite were out for a while. They do amazing things, like enabling humans to have a crisp view about the contents of a link. Unfortunately, until IIS 7 Microsoft didn’t had nothing comparable as default, but some companies struggled to offer this basic service.The two options were the rather cheap IISRewrite and the free ISAPI Rewrite Filter.
Mr Thomas Deml, Lead Program Manager in the IIS team, responsible for Security, Performance, Shared Hosting, presents in his overview about how SEO can be added to your application in his breakout session in MIX 09
Come learn SEO best practices and proven techniques that can boost the position of a Web site in search results pages.
Instead of having www.blabla.com/index.aspx?q=cats you can create a redirect to same page, but have instead the link www.blabla.com/search/cats. This enables the search engines to operate more efficiently in serving their customers (which can be also your customers, by the way) more accurate responses to their needs.
Usability
0Is Microsoft learning basic principles of Usability?
Corrina Black, lead designer for the Silverlight platform, presents usability principles implementation in the newest Silverlight 3. She is focused very much on design, so no coding best practices will be heard here. Only good advices on how to create an appealing, easy to understand interface.
MIX09 Scott Hanselman’s FILE|New Project …
1Scott Hanselman had a presentation at Mix 09 conference – File | New Company: Creating NerdDinner.com with Microsoft ASP.NET MVC. This was in its unique style – fun, rich in content, tricks, advices but most of all was fun.
This year he managed to create a new type of presentation – without the actual presentation! No more constrained to some slides, just him, Visual Studio and the audience. Yes, the audience – who seemed to absorb any words spoken there, helping Scott with few advices in some key points.
Adamo by Dell – contralaptop to MacBook?
4
The newest line launched by Dell, having as target the MacBook fans, seems to meet the expectations. Slim, slick, powerful, with quite big battery autonomy, seems the perfect response to the Mac version.
Since I can’t compare the systems more that by looks, seems that Dell slaps the Apple in face – it is the first time when a device really levels to the looks of an Apple MacBook. Crisp screen, clean design, lightweight – seems that the managers have a new shiny toy at their disposal.
I will let you discover the rest…

Working in Fraunhofer Institute of Technology
2Starting today, I work as a Student Helper in Fraunhofer Institute for Applied Information Technology. The branch from Sankt Augustin, which I joined, is focused on the research of human-centered computing in a process context. I will activate in the Cooperation and Community Support department, which deals with the research and development of community portals, (mobile) communities and cooperation, Internet-based groupware, cooperative knowledge management, application service providing for cooperative work and virtual teams, rating and recommender systems and cooperative learning environments.
The head of the department is Prof. Wolfgang Prinz, PhD and I will work closely with Mr. Nils Jeners, researcher in FIT. I had the pleasure of attending Mr. Prinz course, CSCW and Groupware, while being student in the Media Informatics Master, held by RWTH Aachen University. CSCW stands for Computer Supported Collaborative Work.
My first task is to study the Twitter community, applications based on it and the actual phenomena. My work should help in better understanding the aspects of human behavior, social interaction between humans and in particular the tools and services used for microblogging. This will allow also to discover ways to extract patterns in the context of this technology, who is changing the ways that people interact and socialize over the Internet.
