October 2005 - Posts
Following the reactions I got from a previous post, I decided it was time to fight back against the Microsoft pasta people! (Beware: I still like spaghetti but with tomato sauce)
So I would like to introduce my new logo (feel free to use it on your blog):
I AM NOT
A SPAGHETTI CODER
Now next in our video series, Clare Dillon Microsoft Ireland and some nice comments on the history of INDA and generally on the role of communities.
If I started a community in Ireland, I have to say because of Clare who help me a lot building a now 900 members user group.

I installed the .Net 2.0 package on web server. But it seems I have some problem with .Text. Anybody has done this and can tell what are the modifications to make .Text working?
This is the error message:
System.InvalidOperationException: The WebResource.axd handler must be registered in the configuration to process this request.
Thanks for the help.
Ok we continue our videos show by Ian Griffiths, who was one of our speakers at INDA conference in Dublin.

Ian (and Chris Sells) have also released what seems to be the first book on Avalon aka WPF
Over the last few months, I try to read and prepare some book reviews regarding ASP.NET 2.0. So with all my personal subjectivity, I found myself embroiled in some sort of conspiracy by the C.S.G. aka the Code Spaghetti Generation.
I was quite sure this was an extinct cult from the Asp 3.0 time circa 1999. They are now invading our brains in every book or article I read and this look like a revival cult of some kind or a pervasive plot to conquer the developers world.
See this piece of code (Warning: if you are a DBA or a Business Object guru this might hurt and make you scream):

So if you are reading this line, and you are still alive, stop reading here.
Well for many years I was told this was a bad practice to mix presentation layer and data layer. So why the C.S.G. is back again? To please the beginners? Any typing mistake when you want to update your HTML code on this page will doom your worthy application.
So please can all the ASP.NET 2.0 writers add a small comment on this kind of thing and say something like 'Don't do it kids it's cool but it's really bad practice and it will send you to code hell'.
I propose a new logo to ban all the C.S.G. people from our web applications.
Wow, thanks to S.B. Chatterjee, I know I am 'virtually' rich. So where I can claim the money now :-)
Ok we start the videos show by Dino Esposito, who was our first speaker at INDA conference in Dublin. Amazing that the subject Dino choose for the conference is also an article written by himself in the October edition of Asp.netPRO magazine.
Thanks to Philip McKeown for being so good behind the camcorder and also for the production of this series.

Google has launched a new service but play with our nerves by switching on and off the service all the time. Well at least the entry page is really there but this morning I was unable to enter.
From Google blog this is what you can learn about Google Base:

You may have seen stories today reporting on a new product that we're testing, and speculating about our plans. Here's what's really going on. We are testing a new way for content owners to submit their content to Google, which we hope will complement existing methods such as our web crawl and Google Sitemaps. We think it's an exciting product, and we'll let you know when there's more news.
The Microsoft .NET Framework Version 2.0 Redistributable Package is also available for download now.
