Somehow, an accident caused my HTC G1 to drop into the toilet bowl. I quickly took it out and I was amazed it was still working. After a while, the display started to fade, and the phone switched off on its own.
Undaunted, I left the phone @ the back of the PC, and started blowing @ it. After 3-4 hours, I tried to switch it on, and to my surprise, it worked! Over the next few days, I tried various functions, and it still worked for me.
Can you say the same for your phone? Can your phone even survive a trip to the beer garden?
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.
