How to negate a method reference predicate
...ows how by explicitly casting the method reference to a Predicate and then converting it using the negate function. That is one way among a few other not too troublesome ways to do it.
The opposite of this:
Stream<String> s = ...;
int emptyStrings = s.filter(String::isEmpty).count();

Linq Syntax - Selecting multiple columns
...ct(x => new { x.EMAIL, x.ID });
AFAIK, the declarative LINQ syntax is converted to a method call chain similar to this when it is compiled.

Pandas - Get first row value of a given column

Although this works, it is taking ...
