C# 9. 0 in a Nutshell:

Embarcadero Delphi, formerly CodeGear Delphi and Borland Delphi, is a software development environment for Microsoft Windows applications originally developed by Borland and now owned and developed by Embarcadero Technologies. Delphi 2010 is the most recent version and is distributed in three different editions: Professional, Enterprise and Architect. Delphi was originally a confidential research project at Borland which evolved into a product that was to be called AppBuilder. Shortly before the first release of Borland's AppBuilder, Novell AppBuilder was released, leaving Borland in need of a new name. After much struggle, the name Delphi prevailed.

“Beethoven’s five sonatas for piano and cello show in a nutshell the same evolution that the 32 piano sonatas show. You have this wonderful young lion Beethoven in the opus 5 sonatas, you have the opus 69, the A major, which stands in the middle of his life, and then you have these wonderful two works, opus 102, which are at the gates of the late style, the last phase. And these are in a way experimental works, but fully crystallized.”
