Why are mutable structs “evil”?
...w and then - especially with your Business Model, where you want streaming etc. to work smoothly with existing solutions. I wrote an article on how to work with mutable AND immutable data, solving most issues around mutability (I hope): rickyhelgesson.wordpress.com/2012/07/17/…

How to set a Default Route (To an Area) in MVC
...or the simple purpose of switching your view engine (i.e. to Spark, NHaml, etc.). In this case, it's not the View-creation logic we need to override, but the FindPartialView and FindView methods in the VirtualPathProviderViewEngine class.
You can thank your lucky stars that these methods are in fac...
Programmer Puzzle: Encoding a chess board state throughout a game
...We could simply store the the text of the move here (“e4”, “Bxb5”, etc). Including a terminating byte you’re looking at about 6 bytes (48 bits) per move (worst case). That’s not particularly efficient.
The second thing to try is to store the starting location (6 bits) and end location (...
How can I view the source code for a function?
..., what type(s) of objects its return type is, whether and how it recurses, etc.
To redirect to a separate file (so you can bring up the code in your favorite IDE/editor/process it with grep/etc.):
capture.output(getAnywhere('rfcv'), file='source_rfcv.r')

...ect a. So, primarily, a is an object and b is a member (function/ variable etc) of a.
Arrow operator is used in indirect member selection scenarios.
print(a->b)
Here, we are accessing b which is a member of the object, that is pointed to by a. It is shorthand of (*a).b and so here, a is pr...
What is the performance cost of having a virtual method in a C++ class?
...predicted. This can cause a large pipeline bubble as the processor cannot fetch any instructions until the indirect jump (the call through the function pointer) has retired and a new instruction pointer computed. So, the cost of a virtual function call is much bigger than it might seem from looking ...
Exporting functions from a DLL with dllexport
...ct not C++. C++ DLLs rely on name-mangling for all the C++isms (namespaces etc...). You can compile your code as C by going into your project settings under C/C++->Advanced, there is an option "Compile As" which corresponds to the compiler switches /TP and /TC.
If you still want to use C++ to wri...

...hen all the commit tags change, and all metadata (code review discussions, etc.) are orphaned or need to be updated.
