Look for a [NotMapped] property with name Foo in your DB Model.
Look for a property with the same name, Foo, in your View Model.
If that is the case, then change your AutoMapper config. Add .ForMember(a => a.Foo, b => b.Ignore());

Split string in Lua?

Doesn't work if string contains empty values, eg. 'foo,,bar'. You get {'foo','bar'} instead of {'foo', '', 'bar'}

What is move semantics?
...to members
Sooner or later, you are going to write code like this:
class Foo
{
unique_ptr<Shape> member;
public:
Foo(unique_ptr<Shape>&& parameter)
: member(parameter) // error
{}
};
Basically, the compiler will complain that parameter is an lvalue. If you...

“for” vs “each” in Ruby

Never ever use for it may cause almost untraceable bugs.
Don't be fooled, this is not about idiomatic code or style issues. Ruby's implementation of for has a serious flaw and should not be used.
Here is an example where for introduces a bug,

So, we see that

is semantically the same as:

They are not exactly the same because Python evaluates the foo expression (which could be a dotted lookup and a function call) befo...
How do I dump an object's fields to the console?

The to_yaml method seems to be useful sometimes:
$foo = {:name => "Clem", :age => 43}
puts $foo.to_yaml
returns

(Does this depend on some YAML module being loaded? Or would that typically be available?)

how does array[100] = {0} set the entire array to 0?
...d the initialiser.
If your array is auto, then it is another story.
int foo(void)
{
char array[100] = {0};
...
}
In this case at every call of the function foo you will have a hidden memset.
The code above is equivalent to
int foo(void)
{
char array[100];
memset(array, 0, sizeof(array));

Recursive Lock (Mutex) vs Non-Recursive Lock (Mutex)
...s not efficiency. Non-reentrant mutexes lead to better code.
Example: A::foo() acquires the lock. It then calls B::bar(). This worked fine when you wrote it. But sometime later someone changes B::bar() to call A::baz(), which also acquires the lock.
Well, if you don't have recursive mutexes,...
