Re: C# Exam
Go ahead Benedikt.Create a wiki page with objectives similar to Java SE - Basic, for C#

Re: C# Exam
Okay I will develop objectives and post them then there.regards

Re: C# Exam
John,Question on the vision for this site: It is called JAVA black belt. I understand having related technologies: Ruby, SQL, design, etc. I don't follow C# though as it directly competes with Java. I don't imagine many C# developers coming on a site with Java in the name. Or are you trying to make a "coders black belt" type thing?
Re: C# Exam
Hello!I think a C# exam does not make the jbb site to a java site. It does not require expert knowledge only basic language features are covered. And I think it is not that bad if a developer knows more than one language. Additionally C# has more in common with Java than Ruby or other languages.
I have defined one basic and one intermediate exam.
I do not think that it will hurt the jbb platform.
Since I do not defined more exams like collections or reflection.
The exams are based on c#2.0 if it is recommended I can also define one for c#3.0.

Re: C# Exam
I agree with Jeanne.Having C# exam on JavaBlackBelt is not opt I feel since it is competing technology to Java, and is no where used by a Java programmer as of I know.
On the otherside, C# programmers wont come to the place where there is a word "Java", to take the exam.
For any other marketting reasons, if John likes to have this exam, then I dont know, and no objections at all..
thanks,
Amzad Basha.
Re: C# Exam
Jeanne, Amzad.I understand your questions.
I'm used to go to Java conferences meet Java developers.
Once a year, I go to JAOO, a Java & .Net conference. It's quite different. Their sessions are made for developers. They don't consider that the world is splet into Java programmers and .Net programmers. I meet many developers having worked with both. They are IT developers before being Java or .Net. That made me think
We just open the door, as for Ruby.
When/if we'll have 5 successful .Net exams with an interested community around, I'm not against opening DotNetBlackBelt.com, or DevBlackBelt.com.
For the moment, let's make these guests feel home in our Java Community and show them how open we are.
I hope this answer your questions.
Kind regards.
John.
Re: C# Exam
Hmm.. It sounds good. I am convinced...Thanks John!
Cheers!!

Re: C# Exam
HiI agree with John. However I understand also Jeanne. But I'm wondering about the marketing aspect of this move. It would be good idea to create sth like separated tiny little site for non-java exams, sth like an incubator. And create a separated knowledge points pool for these. Contributions points can be shared for among the all BlackBelt platform but i believe that we don't to add Java developers points for the passed Ruby exam.
I personally like Ruby a bit and look forward for sth similar to the JBB for Ruby programmers in order to exchange my knowledge with the Ruby professionals (since I'm not the one). However we need to encourage non-Java people to contribute and locating this exam on JAVAxxx page (as well as merging kng points gained with the Ruby exam with the java points) is not a good idea. I will deter the Ruby guys from our exams.
In general we should reconsider again the problem of multiple tracks (like Spring, Hibernate, SQL). Old single, knowledgePoints-based tracks is not an adequate model for a portal with such great amount of exams as JBB.
Possibility of having specialized minor-tracks in for example Ruby+Rails+SQL or JavaSE+SQL+Spring would be a much better idea. Don't you think so?
Regarding the exam. Benedikt, could you create the wiki page?
Best regards.

Ideally, we should make RubyBlackBelt.com, but I suggest that we focus on JavaBlackBelt.com for the moment. Welcoming a Ruby or C# exam is a kind of investment for the future. Setting up a whole community RubyBlackBelt.com is big effort, just to make people know the site and come.
For .Net, a partnership with Microsoft would ease to take the decision.

People taking "any" exam get rewarded through the belt track. The idea of mono-technology tracks was "certify" people in that technology.
Your idea of multi-technology tracks sounds more like learning paths to me. Users would go for a path and have a multi-exam goal, more sequential than a belt (in the belt system, they are too free).
Kind regards.
John.
