Despite leaving CodeGear in April 2008, I have been silently watching and passively reading all the newsgroups and forums. And thus, that was how I came across Nick's posting that he was let go from Embarcadero. Is this a good change for Delphi or Nick? Is it a consolidation of manpower resources at Embarcadero, or is this an indication of something else?
I've no idea.
In 2017, with the release of Delphi 10.2 Tokyo, Embarcadero introduced a specialized implementation of the Observer pattern into the System.Classes unit. While it has been in the wild for 9 years, it remains a "hidden" architecture for many, primarily because it serves as the invisible engine behind LiveBindings. Other than live bindings, you can also use the Observer pattern as a way to update component settings to the Windows registry, an .ini file, or persist it elsewhere.
