i have few locations in parse i'm query-ing. shows annotations zoom last one. how can find max , min latitudes , longitudes , make them fit ? there plenty of these on stackoverflow they're in objective-c. the examples in objective-c still valid since underlying sdk/api still same -- being called using different language (and there's documentation). to show annotations, there 2 ways it: use convenient showannotations method. pass array of annotations , automatically calculate reasonable region display. call after adding annotations (after for loop). in fact, showannotations add annotations if aren't on map. show annotations on map, pass map's own annotations array. example: self.mapview.showannotations(self.mapview.annotations, animated: true) if not happy default region calculated showannotations , can calculate 1 yourself. instead of calculating minimum/maximum latitudes , longitudes, etc, prefer use built-in mkmaprectunion funct

i'm writing optimized windows based shellcode in c++ , have problem avoiding hardcoded addresses in c++ while passing function. e.g: my_createthread(null, null, (lpthread_start_routine)&thread_callback, null, null, null); dword winapi thread_callback(lpvoid lpparam) { // stuff.. } in disassembly, shows createthread(..., cardcoded_address, ..); instead, want pass address "from location thread_callback" is there way avoid it? (because shellcode should address independent?) regards. anyways, searching/doing stuff , final thing i've done can solve delta offset. explanation: @ first function of code, there should function this: dword delta; __asm { call getbasepointer getbasepointer: pop eax sub eax, getbasepointer mov [delta], eax } you can google delta offset more details. afterwards, can this: my_createthread(null, null, (lpthread_start_routine)((dword)thread_callback + (dword)delta), null, null, null); dword

is possible (how) addon allow specific function in document/page/content scope run in browser scope? (i aware of security implications , specific , specific purpose.) as general example, xmlhttprequest in content script has content scope. gm_xmlhttprequest via greasemonkey has browser scope. imagine having gm_xmlhttprequest in content script , wanting addon allow gm_xmlhttprequest run in browser scope. there 3 separate security scopes (called principals ) involved when scripting page. the system principal (full access everything, including operating system apis) the expanded principal of sandbox may scoped 1 or more origin domains. when scoped single domain it's still considered more privileged content itself the content principal of page itself so if want run addon-script performs cross-origin xhr you not need grant privilege page content itself . you need grant sandbox in addon-script runs, separated xray-wrappers untrusted page-content. if you

i've seen number of articles, , questions of focus on cost of exceptions, performance benchmarks, , so. but nothing seems explain why slow. happens under-the-hood magnitudes slower when 1 thrown. articles stack unwinding makes slow. don't understand why makes magnitudes slower. from brief understanding of seh, every time thread enters try block, has add say, kind of marker location onto exception chain in tib. has costs, while trying walk stack. understand part. doubt that's half story considering magnitude of performance loss. also, why have unwind stack if exception being caught in same function. why case still equally slow? could please explain going on in simple terms?
