Lock-free multi-threading is for real threading experts
...pattern (I'm not as familiar with what's available in native-compiled C or C++ and it's harder there due to no garbage collection). Perhaps you and I have a different definition of spinning: I don't consider the "CAS-retry" you find in lock-free stuff "spinning". IMO "spinning" implies hot-waiting.

Why is TypedReference behind the scenes? It's so fast and safe… almost magical!
...nse if TypedReference was documented just for one language -- say, managed C++ -- but if no language documents it and so if no one can really use it, then why even bother defining the feature?)

Declaration/definition of variables locations in ObjectiveC?
...sually around non-ObjC ivars (like Core Foundation objects, and especially C++ objects if this is an ObjC++ class), or ivars that have weird storage semantics (like ivars that don't match with a property for some reason).

What do 'statically linked' and 'dynamically linked' mean?
...ked' and 'dynamically linked', often in reference to code written in C , C++ or C# . What are they, what exactly are they talking about, and what are they linking?

When is assembly faster than C?
...n heavy fixed point code by writing a couple of asm-lines.
Using Visual C++ 2013 gives the same assembly code for both ways.
gcc4.1 from 2007 also optimizes the pure C version nicely. (The Godbolt compiler explorer doesn't have any earlier versions of gcc installed, but presumably even older GC...
Do zombies exist … in .NET?
...ie threads with .NET code. I probably could have figured out that calling C++ code that's known to cause that issue from .NET code would produce the desired effect. You obviously know a lot about this stuff. Do you know of any other cases (possibly weird, but not weird enough to never happen unin...
Most simple but complete CMake example
...example add some compiler flags
target_compile_options(example PUBLIC -std=c++1y -Wall -Wfloat-conversion)
# this lets me include files relative to the root src dir with a <> pair
target_include_directories(example PUBLIC src/main)
# this copies all resource files in the build directory

C dynamically growing array
...no built-in dynamic array in C, you'll just have to write one yourself. In C++, you can use the built-in std::vector class. C# and just about every other high-level language also have some similar class that manages dynamic arrays for you.
If you do plan to write your own, here's something to get yo...
Is a statically-typed full Lisp variant possible?
.... For example, it's not at all comparable to a statically typed list, like C++'s std::list or Haskell's list. Those are single-dimensional linked lists where all the cells are of the same type. Lisp happily allows (1 "abc" #\d 'foo). Plus, even if you extend your static-typed lists to cover lists-of...
How should one use std::optional?
...nd how does it compensate for what was not found in the previous Standard (C++11).
