What is Duke Dollars

i am a new user to java forum,i want to know about the Duke Dollars

The FAQ there is a little out of date.
They don't give away prizes anymore like it says (I have heard from of at least one person who got something)
Since that time Duke dollars have become a bit of a joke.
Too many people were "cheating" with dukes - just creating throwaway names, and awarding themselves duke dollars.
You used to be able to see how many duke dollars a person had - which was a small indication of the "expertise" of the person. That was removed in one of the forum "upgrades"
So now you can't even use them for that. You can still issue them if you want to. It probably won't affect the answers though.

What are Duke Dollars?

I would just like to know what Duke Dollars are and what they do for me, can I make money with them, can I feed the poor with them?

I was wondering myself. To answer your questions, looks like no and no.

Duke Dollars, What are they and why are they in this forum?

Hi,
Can somebody please tell me what duke dollars are and why they are in this forum? some topics have duke dollars, but don't know what that means.
Thanks in advance
Arjen

hahahahha... the moment i posted this topic, i received the link to assigning dollars to a topic as well as a link to what duke dollars are. :) lol

I wanna assign you ALL my Duke Dollars....

...for a new question i have BUT b4 I can do that I need to retrive back the duke dollars from my earlier messages that haven't been answered and have my dollars gathering dust...how on earth do i do that?

Silkm I have no issues with assigning you all my dukes from all those earlier questions...just go there, type anything and I will assign them to you if u can solve my query...
It's gotta do with setting the classpath...and yes, i have already been thru google and forums here...
This is what i do:
- Start>Control Panel>System>Advanced>Environment Variables
- Click on Path in the System Variables section
- Click Edit and add C:\Program Files\Java\j2re1.4.1_01\bin AFTER %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;c:\Program Files\Common Files\Adaptec Shared\System;
- Next I go to DOS and get my C prompt to C:\Program Files\Java\j2re1.4.1_01\bin
- I type javac helloworld.java and ENTER
- I get "javac is not recognised as an internal or external command, operable program or batch file"
So then I go back to Start>Control Panel>System>Advanced>Environment Variables
- This time I click on New in the "User Variables for Gaurav" section(that's me) - after all i am logged in as Gaurav on my XP machine!
- I type Path in Variable Name and C:\Program Files\Java\j2re1.4.1_01\bin in Variable Value
- Save
- goto DOS
- type helloworld.java and get "javac is not recognised as an internal or external command, operable program or batch file"
BTW i have installed j2re-1_4_1_01-windows-i586 on a XP machine
HELP!

I'd tell you if there were some Dukes on offer.

Is there a place in the JDC where you find find a list of who had the most duke dollars? I think they had this a long time ago, but I'm not sure what happend to it.
Thanks,

SDN Forum points vs Sun Forum Duke Dollars

I believe that a points system is a great way to encourage participation by the community in problem solving.
With the points system in SDN, however, there is room for abuse, for example, by having people you know award points to you on threads.
I personally like the points reward system (Duke Dollars) on Sun's Developer Forums. In this scheme, you work with credits. Every user is given a certain amount of points (Duke Dollars) when they join. When you post a question, you can assign a number of Duke Dollars up front from your available credit as a reward to entice responses. You can also accumulate more Dollars by answering threads which have Dollars assigned.
Every month, Sun gives a gift to the user who has accumulated the most points.
I'm not sure that this solves the problem of users not assigning points for valid help, but, because users are working with limited credit, it does force them to be careful when assigning points, and prevents abuse as that mentioned above.
I would like to hear what other people think about this scheme. Perhaps there are aspects I have not considered.
Regards,
Martin

Would a moderator make it more positive?
Actually Craig went into each of the forums and published a "rules of engagement". Maybe that kind of a "sticky note" post would be the place to remind people about the inappropriateness of redundant questions (across various forums) and the confusion and poor sporting behavior associated with "copied" answers. I can ping Craig with that suggestion to add text if you think it makes sense to "remind" people in each of the respective forums.
Or..to be a little more provocative, we could suggest that community members who have a good track record of participation, collaboration, and exemplary attitude be given the moderator rights in forums where the activity volume might be too overwhelming for an SAP moderator alone to manage and given the rights to move content to a more appropriate thread.
This is what I meant about "self-policing". Also, perhaps the moderators (internal as well as SAP) could identify themselves in a sticky post and invite participants in those designated threads to track "abuses" or issues, thus identifying them and hopefully resolving them publically.
Strange, it reminds me that in old, Puritanical, America, of the 17th century community culprits were subjected to a public dunking or stocks when they broke the law. The purpose being that public condemnation sent a clear message to other "would be" misbehavers.... and thus deterred further bad conduct.
While a rather radical and unpleasant method it was an open way of dealing with abuses to the system.
Perhaps others can offer less extreme and more effective suggestions here

"My Duke Dollars"

Go to your "My Duke Dollars" and click on the link to "Duke Dollars Rewards Program Account Summary".

And??What does it give you because for me it gives memy
'profile management'?No. I get my list of dukes spent, gained, totaland
recent activity.I too. Sometimes. Other times, I get a 404 or a
log-in and my profile.Do you remember all the shenanigans with your user profile. How you had to confirm something or whatnot a couple of years ago so they could "centralize" and "streamline" the one Sun account login thingy?
That worked out well didn't it. Much better now.
Vote "Don't touch it!" in Sun's feedback poll http://forum.java.sun.com/thread.jspa?threadID=710736&tstart=0 Sun should fix the bugs in the forum software before fiddling around with the GUI.

How are duke dollars distributed?

Hi all,
I wonder.... For the last 2 months, I replied on several messages with Duke Dollars on it. But those Duke dollars were never attributed to anyone. Very often there wasn't even a feedback from the person that posted the message.
What happens with those dollars?
Marc

Don't let others fool you.
I am collecting all unassigned dukes. Just post the
threads you have been answering and I'll make sure you
get those dukes (charging only a small fee).Don't trust him! He said he would collect for me but instead he intimidated the user into giving him all their Duke Dollars!

10 Duke Dollars if you help me set up tutorial

After several posts to this forum w/o any success, I am now offering 10 Duke Dollars to get this problem fixed:
I am trying to work through the j2ee tutorial on a Windows XP platform, specifically the servlets section which requires me to build the bookstore1 example (chapter 11). I am having problems with using asant to compile and package the project. I have been at a complete standstill for about a week now because I cant get the example to run - Im tearing my hair out, so plese help me!!!
The command I am using is asant create-bookstore-war. This throws about 80 compilation errors because classes referenced within the source files are not found . I therefore know that the compiler cant find the classes (suggesting CLASSPATH problems), but I dont know what settings Im supposed to be using.
Some info for you:
I tried adding JAVA_HOME and J2EE_HOME to the environemt variables, pointing to the java sdk (inside the app server) and J2EE application server installation location respectively. This didnt work. Initially I had JAVA_HOME pointing to a seperate installation of the SE SDK I had, but since discovering the SDK inside the appserver, I uninstalled J2EE, J2SE SDK, and re-installed J2EE, using the enclosed sdk as JAVA_HOME. None of this solved my problem.
I think I know now that the environment variables are not anything to do with the tutorial - this is just for the locations of the J2EE and J2SE SDK command path files - is this correct? In which case, using J2EE_HOME and JAVA_HOME is just for shorthand declarations in the environemtn/system variables?
(As you can probably guess by now I have spent a lot of time trying out different things!!!).
I also tried setting the j2ee.home and j2ee.tutorial.home attributes in the build.propoperties file located in <INSTALL>/j2eetutorial14/examples/common. This didnt work. I also tried setting the admin username property in this file, and the corresponding password in the password file (cant remember offhand what its called). Again, no luck.
In another post, somebody asked for the following oputput from my system:

Heres the last couple of errors on running asant creat-bookstore-war. All errors are cannot resolve symbol, so im sure its a classpath problem.
I only have PATH properties set in the environment variables, and the set CLASSPATH only points to my own J2SE packages.

I'm trying to make i(to the power of n) over n.quickanswer=MANY duke dollar

I will pay many duke dollars for a quick answer to this.
i(to the power of)n
the full equation is r=---
n
heres what i did:
class Project
     public static void main(String[] arguments) {
          int P = 0;
          int r = 0;
          int n = 0;
          int t = 0;
          int i = 0
          int interest = i public static double exp(n) / n;
          system.out.print("The Interest rate is" + interest);
          int rate = 1 + r public static double exp(1/n) h;//the effective rate
          system.out.println("The effective rate is" + rate);
     int A = P (1 + i public static double exp(n) /n) public static double exp(n*t);
The program isn't finished i have to get this far without errors

one last thing. could you just go over this briefly and quickly?
class Project {
     public static void main(String[] arguments) {
          int P = 0;
          int r = 0;
          int n = 0;
          int t = 0;
          int i = 0;
          //these values are put in by you, the user.
          int interest = Math.pow(i, n) / n;
system.out.print("The Interest rate is" + interest);
          int rate = Math.pow((1 + r), 1/n) ;//the effective rate
system.out.println("The effective rate is" + rate);
          int A = P * Math.pow( (1 + Math.pow(i, n) / n), n * t); system.out.print("The total holdings (A) is" + A);
          int e = Math.pow(1 + (1 / n), n);     system.out.print("The return (e) is" + e);
          int time = P Math.pow(1 + r, t);
system.out.print("The time needed to double?");
system.out.print("The time needed for this principal is" + time);

Cheap problem with duke dollars

i have 17 duke dollars but i can not give then
along with questions i ask...
what to do...

At the top of the thread, you should see a link saying "assign Duke Dollars". Click on this, and select how many from the drop-down box. Then click on the button "Assign Duke Dollars".
Next go back to the thread, and by each person's name you should see a little picture of a Duke with a green +. Click on that to assign Dukes to that person.

How do you add Duke Dollars to a post???

How do you get the little Duke Dollars thingy to show up next to your post? There are no buttons to do so on the page where I'm ttyping this, nor on the preview page. Nor does it say anything about it in the Duke Dollars FAQ.

Oh never mind! I saw the option to add Dukes appear after the message was posted.
IMHO you should be able to add Dukes either on the form or the preview page.

Using WAIT to repeatedly check a file !!Duke dollars!!

I have created this method, it is supposed to read a text file when a button is pressed after i have allocated an amount of time to check the text file. the text file must be checked every 2mins or so to see if there have been any changes!
i have some code here but 'wait(10000)' doesnt seem to have any effect!
can anybody help
theres 15 duke dollars in it for the best solution
cheers everyone
