How to choose an AES encryption mode (CBC ECB CTR OCB CFB)?

CCM: A nonce-based AEAD scheme that combines CTR mode encryption and the raw
CBC-MAC. Inherently serial, limiting speed in some contexts. Provably secure, with good bounds, assuming the underlying blockcipher is a good PRP. Ungainly construction that demonstrably does the job. Simpler to implement...

What is opinionated software?
...er defined methods and functions as it leaves the system open to returning raw HTML. So an opinionated framework developer only allows access to data structures. By design, the software is limiting and encourages the designer into doing things their way.

What does T&& (double ampersand) mean in C++11?
...ue_ptr. Since a unique_ptr maintains exclusive ownership of its underlying raw pointer, unique_ptr's can't be copied. That would violate their invariant of exclusive ownership. So they do not have copy constructors. But they do have move constructors:
template<class T> class unique_ptr {

What's the right way to pass form element state to sibling/parent elements?
...n your situation.
If the app is a simple Markdown converter, C1 being the raw input and C2 being the HTML output, it's OK to let C1 trigger a setState in P, but some might argue this is not the recommended way to do it.
However, if the app is a todo list, C1 being the input for creating a new todo...

When should I use C++14 automatic return type deduction?
... work.
As a real-world example, I was asked to change a module from using raw pointers everywhere to smart pointers. Fixing the unit tests was more painful than the actual code.
While there are other ways this could be handled, the use of auto return types seems like a good fit.
