  Running JBoss 7 on Windows Azure — Part II Continuing on where I left it on my previous post, I’m going to explain how the Announcement service works and why we choose that approach. The way JBoss and mod_proxy work now is that every time something changes in the topology, either a new proxy is added or removed or a JBoss node, then the proxy [...]... 07-12-2011, 00:44 από The PK blog by "Cloud Boy" στο The PK blog Δημοσίευση στην κατηγορία: Architecture, Cloud, General, Hybrid, Windows Azure

  A wonderful weekend Believe in the community Last weekend I had a great time. That's thanks to ITPro|Dev Connections conference that took place in Glifada, Greece. It was my first Greek dev conferece as I have only a year and a half that I am back in my country. I never had the chance so far to take a closer look at the community and have a taste of the level and the experience of the developers. I have to admit that I was quite skeptical before going to the event. That's because of my disappointment from the interviews I have conducted for the company I work. There were people that have never heard the term "Design Patterns"!!! I won't get any deeper to the situation as there are many parts to blame and that is not the point of this post. Maybe I will write one in the future... What I want to point out though is that I have met some people that made me believe once again in the potential of my country. Because these people are GREAT programmers, great entrepreneurs and great minds! I would like to list them here (in alphabetical... 05-12-2011, 21:18 από Stories of Software Design στο Everyday's Software Design

  Combinatorics library (Silverlight for Windows Phone) I recently found a very nice article at CodeProject on Combinatorics algorithms implementation (specifically Permutations, Combinations and Variations with Repetition option) using C# Generics: http://www.codeproject.com/KB/recipes/Combinatorics.aspx It uses a lexicographic algorithm, so it allows one to ask for “next” permutation/combination/variation from the collection of all possible ones, in the spirit of C++ Standard Library’s (STL) “next_permutation” [...]... 02-12-2011, 18:15 από George Birbilis @zoomicon στο George Birbilis' blog Δημοσίευση στην κατηγορία: Class, Combinatorics, Free, Library, OpenSource, Posts, Silverlight, WP7

  You have changes? I have Workflow! WF4 uses a service oriented architecture and as a result any problem can be decoupled into smaller, easily solvable and testable services. XAF uses MVC architecture which, in a sense, is very similar to that used by WF4. We can compare XAF’s controllers to WF4 services. Moreover XAF’s Application does the same job as the WF4 server. The upshot of all this is that users should be able to get the feel of WF4 in no time at all. The XAF workflow module introduces a new layer that makes the already decoupled services aware of our business classes.  After this the sky is the limit and over the next few posts I aim to demonstrate some of what can be achieved. For example the next post will focus on creating an event driven workflow initialization engine. To get back to today’s post, we will discuss an implementation that is very decoupled and as a result it has very limited dependencies on other modules. It is worth noting that all XAF’s features are decoupled, persistent objects take on the role of domain mappers.... 01-12-2011, 05:07 από A.Bekiaris's .Net / XAF Blog στο A.

  VB gotcha: when If function isn’t equivalent to an If-Then-Else block Just got bitten by the following: Dim takeN As Integer = If(Integer.TryParse(EdTake.Text, takeN), takeN, itemsCount) I had used that instead of writing in 2 lines: Dim takeN As Integer If not Integer.TryParse(EdTake.Text, takeN) then takeN = itemsCount However, there’s an important difference: “If” is a function, so its arguments are evaluated at call-time.

  November news   The last few months have been exciting here at eXpand. First and foremost the number of you that are contributing to the project has shot up which is great news for all of us! Also (as some of you may have noticed) we have earned ourselves a place in the DevExpress start menu. There has been a flurry of activity on the development side too, as a result we are pleased to offer a host of innovative new features. Finally eXpand is now registered at http://nuget.org/ so it can be accessed via Visual Studio. Contributors! First of all we must all say a big thank you to everybody that has been contributing to eXpand in any way. We appreciate your continuing love and support whether in the form of forum posts, code submissions, user suggestions or simply spreading the good word about eXpand! Our community is very healthy right now, I am proud of the fact that eXpand users are collaborating more than ever and sharing their ideas and stories. Of course at the same time we must thank DevExpress for their steady support... 21-11-2011, 04:06 από A.Bekiaris's .Net / XAF Blog στο A. Bekiaris's Blog

  Using ASP.Net web services in Silverlight 4 applications In this post I would like to present in detail how we can consume .asmx web services from a Silverlight 4 application. Silverlight supports and “recognises” web services in a similar way that ASP.Net applications can “talk” to web services. One might say that .asmx web services are considered by Microsoft legacy software. I will not disagree with that. Sometimes we do not have the luxury (time or budget) to create the services from scratch. It is very difficult to convince your boss or client to create a WCF service that does something when the functionality already exists in a web service (.asmx). So if now, I have the chance to write a whole Silverlight application from scratch I would not use .asmx web services, I would use WCF. But as I said before we have to use and maintain legacy code.
