Feb 6	comment	Is there a programming language with not a tree but tags idea behind OOP? @kolupaev: Edited the answer. Take a look at type classes. Do you know .NET'S extension methods? Tags describe too, as typeclasses do. Adding functionality once you got that generic description is just a matter of syntactic sugar.

Feb 2	comment	Are specific types still necessary? +1 Great question
Feb 1	comment	When to use abstract classes instead of interfaces with extension methods in C#? @Gulshan: If it does - for some reason - not make sense to actually create an instance of the base class. You can "create" a Chihuahua or a white shark, but you cannot create an animal without further specialization - thus you would make `Animal` abstract. This enables you to write `abstract` functions to be specialized by the derived classes. Or more in programming terms - it does probably make no sense to create a `UserControl`, but as a `Button` is a `UserControl`, so we have the same kind of class/baseclass relationship.
Feb 1	comment	What should I know about C++? OOP does not solely mean programming with objects, it implies certain design-patterns, runtime polymorphism through inheritance, class hierarchies ... C++ is not really great in expressing these - you need (smart) pointers and often explicit memory management for runtime polymorphism, it's relatively slow and full of pitfalls (ever forgot a virtual destructor?). You often have cleaner ways of expressing the same with pure objects and e.g. generic programming / static polymorphism.

Jan 26	comment	The most mind-bending programming language? The cool thing about Scheme (and Ruby!) continuations is that they are built-in into the language. Haskell basically just adds it's monadic syntax around ordinary continuation passing style, which you can do in Scheme too. But having call/cc built-in everywhere without having to embed the whole thing in a monadic construct definitely allows many mind-bending constructs.
Jan 18	comment	Challenges for the experienced coder to learn functional programming? +1 I like the easy to grasp characterization of Monads/Functors/Applicative. (Arrows as a even more powerful generalization would also fit in)
Jan 15	comment	Prefer algorithms to hand-written loops? `const auto&` is possible? Didn't know that - great info!

Jan 8	comment	What are some reasonable stylistic limits on type inference? While the type-first approach is very elegant in Haskell, I doubt that it's suitable for C++. Without concepts, a C++ template signature basically says nothing - it's the implementation that defines the requirements types and arguments have to meet. Templates just do duck typing at compile time - "try and look if it works". Thus I'd say, we can rather be implicit with the types just as dynamic duck-typed languages are too.
Jan 5	answered	What language, or language feature, do you wish made it to the mainstream?
Jan 4	comment	Naming conventions for variables @Axidos, Fred Nurk: Good points. Point-free style + `_` can really eliminate most useless variables, and it won't be difficult finding expressive names for the rest.
Dec 30	comment	What should every programmer know about programming? @Chinmay, EnderMB: Exactly, indirection is the point here. In any language (except proably Haskell), you need to know indirection to understand how and where data will change.
