What does the “Just” syntax mean in Haskell?
...technical explanations of how Just and friends work; I thought I might try my hand at explaining what it's for.
A lot of languages have a value like null that can be used instead of a real value, at least for some types. This has made a lot of people very angry and been widely regarded as a bad mov...
What really is a deque in STL?
...
@JeremyWest Why not? Indexed access goes to the i%B-th element in the i/B-th block (B = block size), that’s clearly O(1). You can add a new block in amortised O(1), hence adding elements is amortised O(1) at the end. Adding a ne...
Why use Object.prototype.hasOwnProperty.call(myObj, prop) instead of myObj.hasOwnProperty(prop)?
...
Is there any practical difference [between my examples]?
The user may have a JavaScript object created with Object.create(null), which will have a null [[Prototype]] chain, and therefore won't have hasOwnProperty() available on it. Using your second form would fail ...
How is Math.Pow() implemented in .NET Framework?
... Intel. Doing a better job than the Intel engineers is unlikely. Although my high-school book's identity was twice as fast when I tried it:
public static double FasterPow(double x, double y) {
return Math.Exp(y * Math.Log(x));
}
But not a true substitute because it accumulates error from 3 flo...

Haskell: Lists, Arrays, Vectors, Sequences
...to turn in into the immutable structure you want to use with pure code.
My feeling is that you should default to using Data.Sequence if a list is not appropriate. Use Data.Vector only if your usage pattern doesn't involve making many modifications, or if you need extremely high performance within...
How to create a memory leak in Java?
...dreds KB of native memory. Fortunately, Deflater is not widely used and to my knowledge JDK contains no misuses. Always call end() if you manually create a Deflater or Inflater. The best part of the last two: you can't find them via normal profiling tools available.

glVertexAttribPointer clarification
...n order to do so you need to bind your VBO - glBindBuffer(GL_ARRAY_BUFFER, myBuffer);.
And now we can define the attribute - glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 0, 0);. In order of parameter: 0 is the attribute you're defining, 3 is the size of each vertex, GL_FLOAT is the type, GL_FALSE...
