What is Cache-Control: private?
...e last rowversion as an ETag, rather than a date:
200 OK
ETag: "247986"
My ETag can be the SHA1 hash of a static resource (e.g. image, js, css, font), or of the cached rendered page (i.e. this is what the Mozilla MDN wiki does; they hash the final markup):
200 OK

Why do we need fibers
...pose coroutine facility using fibers. I've never used coroutines in any of my programs yet, but it's a good concept to know.
I hope this gives you some idea of the possibilities. As I said at the beginning, fibers are a low-level flow-control primitive. They make it possible to maintain multiple co...
How do I use reflection to call a generic method?
...meof(Sample.GenericMethod));
MethodInfo generic = method.MakeGenericMethod(myType);
generic.Invoke(this, null);
For a static method, pass null as the first argument to Invoke. That's nothing to do with generic methods - it's just normal reflection.
As noted, a lot of this is simpler as of C# 4 us...
What is the difference between the states selected, checked and activated in Android?
...
my custom background color only appears behind selected/focused items, not checked items, when using the post-Honeycomb method you posted above: calling setItemChecked() and then using a selector with property android:state_a...
Framework vs. Toolkit vs. Library [duplicate]
...gether – you just don't have to use all of them.
But that's really just my interpretation of the term. Unlike library and framework, which are well-defined, I don't think that there is a widely accepted definition of toolkit.

What is an IndexOutOfRangeException / ArgumentOutOfRangeException and how do I fix it?
...h a string
Console.WriteLine("First item equals to 'Debug' is '{0}'.",
myArray[Array.IndexOf(myArray, "Debug")]);

Console.WriteLine("First item equals to 'Debug' is '{0}'.",
myArray[Array.FindIndex(myArray, x => x.Type == "Debug")]);
This will fail if no items in m...
What is the JSF resource library for and how should it be used?
...
To start, let's look at how existing JSF implementations like Mojarra and MyFaces and JSF component libraries like PrimeFaces and OmniFaces use it. No one of them use resource libraries this way. They use it (under the covers, by @ResourceDependency or UIViewRoot#addComponentResource()) the followi...

How dangerous is it to compare floating point values?
... we need K. If getting K is more difficult, less intuitive than selecting my VISIBLE_SHIFT then you'll decide what works for you. To find K we are going to write a test program that looks at a bunch of K values so we can see how it behaves. Ought to be obvious how to choose K, if the 'right answe...
What is the “FS”/“GS” register intended for?
...de on 6809 (with and without paged memory), 6502, z80, 68k and 80[123]?86, my perspective is that segmented memory is a horror show and I'm glad it was consigned to the dustbin of history. The use of FS and GS for efficient access of thread_local data is a happy unintended consequence of an historic...
