Dave Nottage alerted me to a paper I've allegedly collaborated with him and Albert Einstein (HTML / PDF).Reads like gibberish though it brings back certain memories, and off I go to search for an earlier work of mine. Ah, here it is! Developing a neural network model: The recognition and conversion of bitmap characters into ASCII code.
Neural networks is something I learnt in the late 90s, while compiler technology is something I learnt in the late 80s. My copy of the Dragon book is still lying around, though no doubt, I've forgotten everything there is to know about compiler technology, except regular expressions which I've used a few years ago to write a IDE feature for a xmldoc functionality.
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.
