I'm guessing that most built in random generators return something like this:
[0.0, 1.0)
so if I would like a 50% chance would I use something like this:
if random() < .5
or something like:
if random() <= .5
Thanks for the help.

Here's the answer:

random.choice([0, 1]) will give you....
Ah, the old ".5" problem.
If I want 50% chance, I'd just check for the LSB (Least Significant Bit).
It's never exactly ).

For our club. We are currently unbeaten in 9 matches away from home and to put that into some sort of perspective we have only achieved that twice before in our history in seasons 1991/92 and 1959/60.
Only once in our history have we managed 10 away games...

Is there any reason why a Java string cannot be tested for equality using it's hashCode method? So basically, instead of....
"hello".equals("hello")
You could use...
"hello".hashCode() == "hello".hashCode()
This would be useful because once a string has...

The hashCode value isn't not to use hashCode as you describe... .
Because: hashCodes of two objects must be equal if the objects are equal, however, if two objects are unequal, the hashCode can still be equal.

When overriding the equals() function of java.lang.Object, the javadocs suggest that,
"it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which ...

You do, however, need it to be identical to all objects that are equal, otherwise code:
public int hashCode....
It's entirely legal to have two non-equal objects return for all objects.
For two equal objects returns the same hashcode.

I know that when comparing String s, you should use .equals() not == and I understand the reasons for this. However I do sometimes forget and compare strings with == by mistake. I would like it if Eclipse (being much smarter than me), would warn me by...

There would be circumstances where you would want to do this exact thing .
Using == is a valid java language feature.
I dont think you can.

If I have a variable in C# that needs to be checked to determine if it is equal to one of a set of variables, what is the best way to do this?

On a side note, with Perl 6 (or Perl 5 and the Quantum::Superpositions module) you can do things like

Anything more complex, use a LINQ query.
Bool b = new int[] { 3,7,12,5 }.Contains(5);
I usually use CoreyN 's solution for simple cases like that .

I am trying to write a function to determine whether two equal-size bitmaps are identical or not. The function I have right now simply compares a pixel at a time in each bitmap, returning false at the first non-equal pixel.

If you are trying to determine if they are 100% equal, you can invert one and add; }
I would start looking in the middle because I suspect there is a much better chance of finding unequal.
Of this technique.

Of whatever object you are comparing it to being defined as equal to everything, but if everyone is playing if that should ever happen, your constant has already gone away, and isn't around to compare equal.
