it possible have type in parent class subclass overwrites? the idea here have shape class, subclasses of rectangles, square, circles, etc. wondering if it's possible overwrite definition of 'shapetype' int property in parent class. this? e.g. in globals.h #define kshapetype_rectangle = 1 #define kshapetype_square = 2 #define kshapetype_triskaidecagon = 13 // try pronouncing this! in shape.h @interface shape : nsobject @property int shapetype; @property int shapeid; @property uicolor shapecolor; @end .... in rectangle.h #import globals.h @interface rectangle : shape @property static (nonatomic, readonly) int shapetype = kshapetype_rectangle; // how working? @end so 2 questions: 1) such thing possible - i.e. redeclaration of parent property static variable 2) yes or no (1), best coding style sort of thing? i'm not experienced in obj-c patterns, if 1 exists, suggest source me @ please? thanks lot! there no concept of objec

i having issue polymorphism in c#. have object implements interface, cannot represent collection of objects collection of interfaces. flies in face of understanding of polymorphism. wondering have gone wrong.

i have php script load data csv files (more 600 mb of csv files) every day on oracle database , remark i/o high on server when script running because files exists on same oracle server , wonder if i/o can cause disk damage. there nothing inherently bad doing this. using disk through normal methods cannot cause damage it, apart normal usage wear , tear. hard drives wear out on time, , heavy usage can cause them wear out faster, not call damage. flash based ssd's wear out after number of writes, more writes wear them out faster, again normal wear , not damage. it may faster read files , perform , queries machine, doing on 1 machine not damage anything.
