How do you generate a random double uniformly distributed between 0 and 1 from C++?
Of course I can think of some answers, but I'd like to know what the standard practice is, to have:
Good standards compliance Good randomness Good speed (speed is more...

I need to generate random numbers with in specified interval [max,min]
Also the random numbers should be uniformly distributed over interval, not located to particular point
Currenly I am generating as:
for(int i=0;i<6;i++) { DWORD random= rand()%(...

If you want numbers to be uniformly distributed over the range, you should break your range up on C++ windows platform..

I'm writing a wrapper around a fairly large unmanaged API. Almost every imported method returns a common error code when it fails. For now, I'm doing this:
ErrorCode result = Api.Method(); if (result != ErrorCode.SUCCESS) { throw Helper.ErrorToException...

What happens if you don't check ErrorCode.SUCCESS ? Will your code quickly fail and throw an exception? Can you tell which unmanaged API failed if your managed code throws? If so, consider not checking for errors and just letting the runtime throw when... .

I wanted to handle all internal errors gracefully, without program termination.
As discussed here , using _set_se_translator catches divide-by-zero errors.
But it does not catch, for example, C runtime library error -1073740777 (0xc0000417) , which can...

You need to install each one.
There is no universal handler.

Tools like Selenium are good for testing user interactions on the web UI. However, I was curious what are people approaches for strictly testing and verifying that web pages are rendered correctly across a set of browsers?
Is this even possible?

Just install as many different browsers as possible and test in all of them .
Manually?
I do not see an alternative if you want strict testing .

According to someone I know, if a question asks about uniformly accelerated motion, the acceleration can be zero. Is this true? I guess I can see how it could be, but... :-/

Because if it starts at rest, then it'll stay at rest which is not "uniform accelerated motion is that it's some non-zero number and it stays there....

Prove that 1/x^2 is uniformly continuous on [1,oo).
Solution:
We know that f is uniformly continuous on a set A iff forall x_n in A,
y_n in A, lim(y_n - x_n)--and we have that...

For a quick direct proof of the uniform continuity of f,
follow the....
Thus f is Lipschitz continuous, hence uniformly continuous.
Proof if you don't understand the definition of
uniform continuity well enough to even state;= 2/3.

Yeah my high school never observed it, then one year all the Black people went all Al Sharpton on their ass and now they observe it .

Hello..
I'm looking for a way to uniformly distribute N points inside a convex
polygon made from X points... I'm working in matlab and right now I'm
just breaking the polygon up into a m x n (such that m*n = N) grid,
selecting the mid point of each box...

Thanks for your uniform distribution

Within a triangle you can uniformly distributed uniformly inside
the polygon and honestly, i'm not sure where to begin.
Into triangles and select each triangle in proportion to its area .

The book I'm following defines a normed space (V, ||.||) as being
uniformly convex as follows:
if for every e x, y.
That failed the uniform convexity property,
so
I think I get the basic idea now.
