Why are Objective-C delegates usually given the property assign instead of retain?
...taining delegates is that you need to avoid a retain cycle:
A creates B
A sets itself as B's delegate
…
A is released by its owner
If B had retained A, A wouldn't be released, as B owns A, thus A's dealloc would never get called, causing both A and B to leak.
You shouldn't worry about A going a...
How to execute Python scripts in Windows?

What is the difference between the states selected, checked and activated in Android?
...single or multiple selection

What are deferred objects?
...xisting ajax() method callbacks can be chained rather than declared in the settings:

CATALINA_OPTS vs JAVA_OPTS - What is the difference?
...and that starts up Tomcat - the "start" or "run" command - but only values set in JAVA_OPTS are passed to the "stop" command. That probably doesn't make any difference to how Tomcat runs in practise as it only effects the end of a run, not the start.
The second difference is more subtle. Other appl...
