What's going on is that the compiler is deciding on what function to call at compile time rather than runtime. Since the type of vh is Vehicle *, it is essentially creating this call: vh->Vehic...
(Full code available for cloning here) I've run into some odd behavior of EF-core's Find method. It seems like the returned entity doesn't include the rest of the data. MWE Models using Micro...
The problem is that you are using row twice with different types. for row in self.diagram: # row is str here for row in self.seed_diagram: # row is list[str] here Renaming one or the other m...

Consider the following method as an example: List<int> Foo() { // ... } Are there any disadvantages of returning an interface instead of a concrete implementation in C#? IList<i...
Grouping related items into modules is of course generally good practice, but it serves a practical purpose as well. The important part here is the #[cfg(test)] annotation. The #[cfg(test)] anno...
Why do we have the "Participate Everywhere" ability when we haven't yet done anything? Bootstrapping. Our communities are still small, so after we rolled out the abilities system we decided to p...
I've heard that in modern C++, smart pointers are preferred to raw pointers for ownership (the so-called RAII principle, as I understand it). This makes sense, and since then I've always used them...
Think of what your for loop is doing, specifically at iterations 11 and 12. for i in range(1,n+2): while not g(i): i+=1;continue a.append(i) In pseudo instructions: for-loop iterati...
What exactly is the Python Global Interpreter Lock (GIL)? As someone who is relatively new to Python, is this something I need to be aware of, or is this just some implementation detail of the inte...

From the Git docs "reset" copies the old head to .git/ORIG_HEAD To restore that commit, you can run $ git reset ORIG_HEAD If you want to restore more than one reset, then you'll have to l...
Say we have an abstract class Foo declared as so: class Foo { public: virtual void test() = 0; }; Let's say that we make a derived concrete class FooDerived, and decide to mark it's ve...
Let's say I have a variant that can hold a bunch of different types of values (say I got them from parsing a JSON or similar). using Value = std::variant<std::monostate, int, double, std::strin...
I was playing around with mapped tuples and came across an interesting case where TypeScript cannot infer the types used: interface Foo<A, B> { (a: A, b: B): any } function test<...
The problem is that the fill function is filling the array with references to the same empty array[1], and therefore modifying that array will affect every entry because all of them are actually th...
