What is the difference between YAML and JSON?
...ople "might" need to look at. I have been subjected to valid criticism by C++ devs who find indentation to be confusing.... especially if there are multiple levels or longer function blocks. Of course... good testable code doesn't have those things, so it's usually not an issue. This is my pers...
Why do we need boxing and unboxing in C#?
...ress is known before you even run the program.
In the next level up, like C++, a second memory structure called the Heap is introduced. You still mostly live in the Stack, but special ints called Pointers can be added to the Stack, that store the memory address for the first byte of an Object, and ...
Functional programming - is immutability expensive? [closed]
...good comparison of FP vs. non-FP. If you want that, check out Haskell vs. C++ at the Computer Languages Benchmark Game. The take-home message there is that the penalty is typically not more than a factor of 2 or 3 or so, but it really depends. (No promises that the Haskell folks have written the ...
Is Python strongly typed?
...t the strong vs. weak typing is more of a continuum than a boolean choice. C++ has stronger typing than C (more conversions required), but the type system can be subverted by using pointer casts.
The strength of the type system in a dynamic language such as Python is really determined by how its pr...
Setting an object to null vs Dispose()
...izer (written as ~Foo() in C#, somewhat confusingly - they're nothing like C++ destructors). It runs the finalizers on these objects, just in case they need to do extra cleanup before their memory is freed.
Finalizers are almost always used to clean up resources in the case where the user of the ty...
What is more efficient? Using pow to square or just multiply it with itself?
...e faster than pow(x, 3), because there is no pow(double, int) overload. In C++, it will be the roughly same. (Assuming the methodology in my testing is correct.)
This is in response to the comment made by An Markm:
Even if a using namespace std directive was issued, if the second parameter to po...
How to build & install GLFW 3 and use it in a Linux project
...ere (at the bottom of the page) and save, exit.
Now compile using g++ -std=c++11 -c main.cpp - not sure if c++11 is required but I used nullptr so, I needed it... You may need to upgrade your gcc to version 4.7, or the upcoming version 4.8... Info on that here.
Then fix your errors if you typed the ...
Is it better to use std::memcpy() or std::copy() in terms to performance?
...ce a performance difference. However, the winner was std::copy.
I wrote a C++ SHA-2 implementation. In my test, I hash 5 strings using all four SHA-2 versions (224, 256, 384, 512), and I loop 300 times. I measure times using Boost.timer. That 300 loop counter is enough to completely stabilize my re...

What is the difference between class and instance attributes?
.... The attribute on an instance is unique to that instance.
If coming from C++, attributes on the class are more like static member variables.
