is vs typeof
.... In cases of T being class, typeof(T) is not reliable since its different from actual underlying type t.GetType.
In short, if you have an object instance, use GetType. If you have a generic class type, use is. If you have a generic struct type, use typeof(T). If you are unsure if generic type is ...

Very simple log4j2 XML configuration file using Console and File appender
...lexible configuration comes in handy when you're trying to separate config from build and put config into a repository elsewhere. Unfortunately, the complexities are making it a bit annoying, but just thought I would throw out a benefit to the flexible options for configuration.

What is the fastest integer division supporting division by zero no matter what the result is?
...fore took philipp's first code and my code and ran it through the compiler from ARM and the GCC compiler for the ARM architecture, which features predicated execution. Both compilers avoid the branch in both samples of code:

What is the difference between a strongly typed language and a statically typed language?
...ically typed
Strongly typed means, a will not be automatically converted from one type to another. Weakly typed is the opposite: Perl can use a string like "123" in a numeric context, by automatically converting it into the int 123. A strongly typed language like python will not do this.
Statical...
Can I list-initialize a vector of move-only type?
