Building a minimal plugin architecture in Python
...in which plugins are active, but that's a nice-to-have.
Of course, any requirement that comes along saying "I don't need [big, complicated thing] X; I just want something lightweight" runs the risk of re-implementing X one discovered requirement at a time. But that's not to say you can't have some ...
Singletons vs. Application Context in Android?
...der, since its life-cycle is handled by the framework. DI frameworks like Guice, Hivemind, or Spring also make use of singletons, but that's an implementation detail the developer should not care about. I think it's generally safer to rely on framework semantics being correctly implemented rather th...
MVVM in WPF - How to alert ViewModel of changes in Model… or should I?
...rised of your ViewModels, and your Models are the just the blocks used to build your application. They typically only contain data, so would not have methods such as DrawCard() (that would be in a ViewModel)

Personally I think Thread.Sleep is a poor implementation. It locks the UI etc. I personally like timer implementations since it waits then fires.
Usage: DelayFactory.DelayAction(500, new Action(() => { this.RunAction(); }));

How does JavaFX compare to WPF? [closed]
