Should the hash code of null always be zero, in .NET
...m, either re-implement the hash code to return non-zero, add a default "unknown" enum entry equivalent to null, or simply don't use nullable enums.
Interesting find, by the way.
Another problem I see with this generally is that the hash code cannot represent a 4 byte or larger type that is nullabl...
What is the difference between a var and val definition in Scala?
...ge the state of that object. At the root of it, however, there was a var.
Now, immutability is a good thing for many reasons. First, if an object doesn't change internal state, you don't have to worry if some other part of your code is changing it. For example:
x = new B(0)
f(x)
if (x.value.value ...
Utilizing the GPU with c# [closed]
...d run on OpenCL as well as Cuda it would be perfect.
EDIT SEP 2013
Cudafy now allows you to compile for both CUDA and OpenCL, so will run the same C# code on on all GPUs. This sounds fantastic, though I haven't tested the OpenCL compiling yet.

# hack hack
$ git commit -am "commit on branch A"
so now there are three separate branches (namely A B and C) with different heads
to get the changes from B and C back to A, checkout A (already done in this example) and then use the merge command:

Lock-free multi-threading is for real threading experts
...accesses, to hide main memory latency and make better use of their cache.
Now, it is sure against intuition that a sequence of code does not flow "top-down", instead it runs as if there was no sequence at all - and may be called "devil's playground". I believe it is infeasible to give an exact answ...
How to deal with IntelliJ IDEA project files under Git source control constantly changing?
... checking out for the first time, but it does seem the best compromise for now. We also had to have the TeamCity inspections work off of the Maven file and an exported inspections profile, but we got that working too. Thank you!

Use of .apply() with 'new' operator. Is this possible?
...or even
// return new (Cls.bind.apply(Cls, arguments));
// if you know that Cls.bind has not been overwritten
}
It can be used as follows:
var s = newCall(Something, a, b, c);
or even directly:
var s = new (Function.prototype.bind.call(Something, null, a, b, c));
var s = new (Function.pro...
