Save byte array to file [duplicate]
...
You can use:
File.WriteAllBytes("Foo.txt", arrBytes); // Requires System.IO
If you have an enumerable and not an array, you can use:
File.WriteAllBytes("Foo.txt", arrBytes.ToArray()); // Requires System.Linq

Specialization with Constraints
...ion with a class constraint. I have a minimal example of my problem here: Foo.hs and Main.hs . The two files compile (GHC 7.6.2, ghc -O3 Main ) and run.

Awkward way of executing JavaScript code [duplicate]
...
var a = (function() {
return foo(bar);
})();
In this case this is really unnecessary, but this is not wrong and it will not throw an error.
But IIF some times uses like module pattern:
var a = (function() {
/* some other code in own scope */

Boost智能指针——shared_ptr - C/C++ - 清泛网 - 专注C/C++及内核技术
...st文档上特地注明的标准bad Practices）：
void test()
{
foo(boost::shared_ptr<implementation>(new implementation()), g());
}
正确的用法为：
void test()
{
boost::shared_ptr<implementation> sp(new implementation());
foo(sp, g());
}

或者将distance放在一个命名空间中,例如：
namespace foo
{
double distance(int a, int b)
{
return fabs(a-b);
}
}
int main()
{
foo::distance(x,y); //now you're calling your own distance function.
}
或者不使用命名空间std,显式声明std::vector...
Difference between static class and singleton pattern?
...s you say that either a singleton or a static method isn't thread-safe? Usually both should be implemented to be thread-safe.
The big difference between a singleton and a bunch of static methods is that singletons can implement interfaces (or derive from useful base classes, although that's less co...
What is the difference between null and undefined in JavaScript?
...he typeof operator returns 'object' for a value that is null. This was actually an error in the original JavaScript implementation that was then copied in ECMAScript. Today, it is rationalized that null is considered a placeholder for an object, even though, technically, it is a primitive value."

Why does one hot encoding improve machine learning performance?
...e. The three possible values of w×x are 0, w and 2×w. Either these three all lead to the same decision (they're all < b or ≥b) or "UK" and "French" lead to the same decision, or "French" and "US" give the same decision. There's no possibility for the model to learn that "UK" and "US" should b...
How can I add a boolean value to a NSDictionary?
...NO / @YES if you are declaring it as a literal. E.g.

foo[@"bar"] = @YES;
