JavaScript: Class.method vs. Class.prototype.method
...dding a property to the function object.
The second function, as you are extending the constructor function prototype, it will be available to all the object instances created with the new keyword, and the context within that function (the this keyword) will refer to the actual object instance wher...

works well, because include paths work out and you can use easy
globbing for install targets.
Bundling dependencies: I think this largely depends on the ability of
the build system to locate and configure dependencie...
What's the role of GetHashCode in the IEqualityComparer in .NET?
...d is called on the Key. The hashcode returned is used to determine the index of the bucket in which the Key/Value pair should be stored.
When you want to access the Value, you pass in the Key again. The GetHashCode method is called on the Key, and the bucket containing the Value is located.
When a...
Invalidating JSON Web Tokens
...er side security, but it does stop an attacker by removing the token from existence (ie. they would have to have stolen the token prior to logout).
2) Create a token blocklist
You could store the invalid tokens until their initial expiry date, and compare them against incoming requests. This seems t...
Why does the JVM still not support tail-call optimization?
...
Diagnosing Java Code: Improving the Performance of Your Java Code (alt) explains why the JVM does not support tail-call optimization.
But although it is well known how to automatically transform a tail-recursive function into a simple loop, the Java specification doesn't require that this tran...
How do CUDA blocks/warps/threads map onto CUDA cores?
...two warp schedulers pick two active warps per cycle and dispatch warps to execution units. For more details on execution units and instruction dispatch see 1 p.7-10 and 2.

5'. If a warp contains less than 32 threads it wil...
Why can templates only be implemented in the header file?
...e, the compiler creates a new class with the given template argument. For example:
template<typename T>
struct Foo
{
T bar;
void doSomething(T param) {/* do stuff using T */}
};
// somewhere in a .cpp
Foo<int> f;
When reading this line, the compiler will create a new class (...

Memoization in Haskell?

We can do this very efficiently by making a structure that we can index in sub-linear time.
But first,

Let's define f, but make it use 'open recursion' rather than call itself directly.
f :: (Int -> Int) -> Int -> Int

When should I use RequestFactory vs GWT-RPC?
... same concrete type on both the client and the server, you can hit a complexity wall based on the capabilities of your GWT client.
To get around the use of incompatible code, many users wind up creating a peer PersonDTO that shadows the real Person object used on the server. The PersonDTO just has...
