Computer Science Foundations

Hello

I made a message board for our class here:

Kind of like the one some of us used for LFSC. I'm hoping it'll catch on, so we can have a better place to discuss everything.

everyone has to go here NOW:

the above site has a lot of cool essays about software. I also like Joel Spotsky's "The law of leaky abstractions" which is mentioned in Dreaming in Code.

I guess it was just a matter of determining how long Mitch Kapor's patience would last, since he has enough money to fuel a dead project for a loooonnnggggg time.

He fed Chandler and the Open Source Applications Foundation for six years on the premise that it would deliver a mind-blowingly innovative PIM (personal information management) suite.

Six years later, Chandler just blows.

OSAF announced this week that Kapor is leaving and taking his funding with him. It's about time.

Another dern sneaky way to steal information.

I'm having this weird problem with my Pascal Triangle program....the program compiles fine but when i run it and enter the number of rows the interactions pane gives me this:

NullPointerException:
at PascalTri.displayRows(PascalTri.java:30)
at PascalDriver.main(PascalDriver.java:9)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

at java.lang.reflect.Method.invoke(Method.java:597)

Can anyone tell me what the hell is wrong with this Diffy code?

Diffy d = new Diffy (n1, n2, n3, n4);
d.printDiffy();
System.out.println();
while (d.isZero() == false)
{
  d.next(); 
  d.printDiffy();
  System.out.println();                                                         
}

E-book that contains thorough instruction in the basics of sets, proofs, and logic for those who need/want a more in depth look at the fundamentals of proof writing.

 Kinda dense but has plenty of examples.  May help clarify what is considered good form in proof writing, as well as giving a more verbose explanation of set theory.
