For defining Agile we should focus on the goal of
Agile rather than on the misleading, very problematic way
suggested by the authors of the Agile Manifesto. Please read

Re: Jms request-reponse not responding in Mule

Claude Mamo — Wed, 21 Dec 2011 06:17:52 -0000

It's a workaround. This was fixed in Mule 3.2, that is, now you don't need to add the ReplyToPropertyRequestReplyReplier processor. The flow will automatically return the async reply.

Agile Architecture is a best way to interacting with market .It’s best way to work with small independent customers focused teams, it’s really best way.

Did you really read the article? Nobody is ranting about rapdily changing technology, just wondering what the best choice is...

Re: Software architecture, PHP and Javascript

Anonymous — Mon, 28 Nov 2011 14:36:43 -0000

No, I don't think so. This article is nothing but a set of assumptions to rant about the known fact that technology rapidly changes. If you want to stand on solid grounds, why don't you become a physicist? That science changes very rarely and still allows an unlimited number of research options. If you don't like the idea of being a theoretical physicist, why don't you become the experimental? Side note: since I've been studying at University, I've been unwillingly observing the problem-solving ability of most people can be summarized in one word as dubious.

Very true, aanbestedingen isn't improving the situation.

Re: 25 million euros wasted, project failed

Peter Paul — Mon, 28 Nov 2011 09:47:43 -0000

There is another interesting mechanism at work here called "aanbestedingen". In order to prevent overspending the feedback cycle between user and development team becomes even greater. In case of a change all kinds of contractual and rules for fair competition come into play. These make feedback and adaption even harder.

By the way my experience is that these government bodies use Prince 2 in name. They don't actual do or act as prescribed by Prince 2. Imho sticking to Prince 2 would raise the success rate of their projects.

I would value it even more if they would reduce the feedback cycle...

Re: XSL-1047: (Error) Invalid instantiation…

Thanks for sharing your thoughts, Andrej. Couldn't agree more that the product owner role is underrated and misunderstood. You can find my view of the role at: http://www.romanpichler.com/bl...

andrej take a look to ItsNat, client-side style of development but in server, pure Java W3C DOM (or other JVM lang) and pure HTML and focused on Single Page Interfaces web sites and applications.
The main advantage of this approach is no need of user defined client-server bridges and strong use of Java instead of JavaScript.

Re: When will we dump server side web frameworks?

andrej — Mon, 05 Sep 2011 04:16:42 -0000

Sure, if you have to support browsers without javascript, this is no option.

Server-side validation is a must, as is database validation. Server-side service (REST) or orm frameworks can handle validation without the need for a user interface mvc web framework.

Re: When will we dump server side web frameworks?

Frisian — Mon, 05 Sep 2011 04:01:50 -0000

There are still environments, where JavaScript is turned off for very valid reasons. Besides, I wouldn't want to work without server-side validation and for that alone a web framework comes in handy.

True, single page apps are not very common in the enterprise, but the frameworks and tools you need are there and maturing quickly. What is still missing before we can start building enterprise javascript applications?

Re: When will we dump server side web frameworks?

Phillips1021 — Sat, 03 Sep 2011 09:15:32 -0000

I don't think single page web applications are very common in the enterprise. I've yet to create a web application that is just one page. Once you go beyond one page and need to have a controller, data conversion, validation, security, etc frameworks such as JEE or Spring provide a great deal of support.
