I guess you're saying to try an algorithm like this:
row 1: start counting from 1st element in row  ie 1 2 3
row 2: keep counting , but this time start from second element in row and then cycle back to 1st element ie 6 4 5
row 3: keep counting , but this time start from third element in row and then cycle back to 1st element ie 8 9 7

That gives constant totals for each column... but what about randomness for each player for the game?
I guess you could
a. interchange columns randomly
b. add and subtract random amounts from random selections in a column -
       the add would need to take the element to >x.y,
       the subtract could take the balancing element to negative
       then add a constant to all elements in the matrix to eliminate negatives
c. find minimum element in the matrix and reduce this, and all other elements by whats needed to get the min value to 1.
After making a nice cup of tea, voila, an apparently random matrix meeting requirements. Maybe.

its the TAB key! I thought I had tried it, obviously not!

When I try to install the sun jdk in ubuntu 9, it seems I get the jre package to be installed first / as well.

The files download, but then I get a licence agreement displayed, seemingly in the terminal window.

But there is no option to accept the agreement.
I've tried pressing return, the space bar, clicking on the [OK] within the agreement. Nothing has any effect -
except closing the terminal window, which then stops the installation.

There MUST be a simple thing I'm not doing or doing wrong. Plz help!

Sorry for the delay in closing this thread - I had a major personal disaster last night.
Thank you so much to all the generous people who offered help.
That really is the spirit of Donationcoders to me and I see it time and time again.
At a really low point in my life, it's meant even more.

Living Room / Help needed from USA to buy a book. - CLOSED

A plea for help...
One of my ex-students (a migrant, no family support) is doing 1st year uni and needs a java text book
(Big Java, 3rd edition by Horstmann).
Cheapest in australia (new) is $137
I see I can get a near new copy from an amazon seller for about $US17, plus postage, which shud come to a LOT less than $137.
BUT the seller only ships to the USA.
Is there a kind DC member from the USA who would be prepared to take delivery of the book if I buy it, then re-ship to australia, after I'd "paypalled" them shipping costs?
Please PM me if anyone would.
Thanks,
Tony
