Traits vs. interfaces
... example of a trait. to_integer would be more likely included in an IntegerCast interface because there is no fundamentally similar way to (intelligently) cast classes to an integer.

How does LMAX's disruptor pattern work?
...he ability to do work in parallel. To do this the Disruptor supports multi-casting the same messages (in the same order) to multiple consumers. This avoids the need for fork stages in the pipeline.
We also allow consumers to wait on the results of other consumers without having to put another queuin...
How can I use interface as a C# generic type constraint?
...var check in par[i].GetCustomAttributes(typeof(ConstraintAttribute), true).Cast<ConstraintAttribute>())
{
if (!check.Check(args[i]))
{
string error = "Runtime type check failed for type " + t.ToStri...
The new keyword “auto”; When should it be used to declare a variable type? [duplicate]
...bdas can't be spelled, so auto f = []... is good style. The alternative is casting to std::function but that comes with overhead.
I can't really conceive of an "abuse" of auto. The closest I can imagine is depriving yourself of an explicit conversion to some significant type -- but you wouldn't use...

How do I grant myself admin access to a local SQL Server instance?

Using smart pointers for class members
...t a client from moving (unless the client is a mad scientist keen on const_casts), I personally wouldn't do it. It exposes an implementation detail, i.e. the fact that ownership is unique and realized through a unique_ptr. I see things this way: if you want/need to pass/return ownership, pass/return...
When is an interface with a default method initialized?
...p->local_interfaces()->at(i);
InstanceKlass* ik = InstanceKlass::cast(iface);

So this initialization has been implemented explicitly as a new Step 7.5. T...
