in windows, when compile simple 'c' program, final executable machine code .exe . same thing using gcc in unix yields .out machine code file. what's difference between these? my basic question is, .exe , .out being machine codes, why operating system dependent? as in, in unix cannot execute .exe directly , in windows, can't execute .out of unix. why so? it has how program loaded. windows , linux have different formats how want program define itself. in linux, elf format used. windows pe . these formats define different data program needed execute machine instructions. also, operating system interfaces different, different libraries need used , different system calls need made. for simple program, can recompile on other operating system have work on both, not able use single file on both.

i need automatically align image b on top of image a in such way, contents of image match possible. the images can shifted in x/y directions , rotated 5 degrees on z, won't distorted (i.e. scaled or keystoned). maybe can recommend links or books on topic, or share thoughts how such alignment of images done. if there wasn't rotation problem, try compare rows of pixels brute-force method until find match, , know offset , can align image. do need ai this? i'm having hard time finding resources on image processing go detail how these alignment-algorithms work. so people in case first find points in images match compute best transformation matrix least squares. point matching not particularly simple , times use human input task, have time calibrating cameras. anyway, if want automate process can use feature extraction techniques find matching points, there volumes of research papers written on topic , standard computer vision text have chapter on thi

i know simple answer, can't seem find solution. created object in own class , trying populate data class. simple data types nsstring, have no problem, when trying make nsmutablearray equal nsmutablearray or when try populate nsmutablearray objects (like strings), keep getting exception errors... here object trying populate: #import <foundation/foundation.h> @interface rssfeedlist : nsobject { nsstring *subject; nsmutablearray *rssfeeddetail; } @property (nonatomic, retain) nsstring *subject; @property (nonatomic, retain) nsmutablearray *rssfeeddetail; @end this how able populate nsstring 'subject' in class: rssfeedlist.subject = @"test"; however, if follow similar convention within same class respect array, throws exception: rssfeedlist.rssfeeddetail = rssitemdetailarray; where rssitemdetailarray nsmutablearray have built in same class. i have tried add items (i tried strings testing) nsmutablearray directly no avail: [rssfeedli
