This article is a transcript from a recorded conversation I had with Anatole Tartakovsky and Victor Rasputnis – my business partners at Farata Systems. This conversation took place on the mountain after the day of skiing. Yakov. There are many ways of creating Web applications and creating them for the enterprises is not the same as developing a Web site for a pizzeria in your neighborhood. During the last five years we’ve been using mainly Adobe Flex for development of the front end of Web applications. Flex applications work in a well known and predictable run-time environment called Flash Player. The code is compiled and you have convenient tools for development. Flex is undergoing “Under New Management” transformations these days. Even though Flex remains the best framework for development of Web applications, you can feel the pressure of HTML5. But using just HTM... (more)

Immersing into JavaScript Frameworks

During the last month my colleagues and I were immersing into the world of modern JavaScript frameworks. We didn’t start from scratch though. My business partners spent the first 5 years of this century porting PowerBuilder, a used-to-be-popular client server tool, to a JavaScript framework. That product was called XMLSP and you can still find its 5-year old version online. The word AJAX was not even invented back then.

The Future of the Flex Framework in Enterprise IT

Disclaimer. Everything posted on this blog is my personal opinion and does not necessarily represent the views of my employer. Part 1. Emotions. Three days ago I’ve received the following email from an enterprise architect of one of our former clients (we’ve conducted two Flex training classes there): “Adobe has been in the news lately with Flash not being developed for mobile devices and then the Flex SDK being donated to Apache. With all these things going on I was thinking if it still makes sense to develop using Adobe Flex for RIA applications. There are several opinions out ... (more)

A Bad Guy Inside my Notebook

This week I’m in Seattle, WA teaching Adobe Flex at the client site. Everyone in the classroom was given a password to the local Wi-Fi router. Everyone but one person successfully connected to the Internet. This unlucky guy was me. In fact, my notebook was connected to the router, but that was as far as I could reach. OK, I was the only person using MacBook. Can this be a problem? Checked the network settings – everything looked hunky dory. I got a valid IP address. One of the students went to see Da Man – sysadmin, who gladly confirmed that my IP address has been blocked by the... (more)
