i attempting create mac os x installer (tried both packagemaker , packages) 2 things on install: check if application installed (by looking through folder structure in applications directory) , set component selections accordingly. setting destination folder of package according folder found in 1. plugin needs go subdirectory of application folder. the former seems it's relatively simple, can add script requirement choice associated each package , let result drive state of component checkbox. the latter feels tricky. know how figure out location of application first step, have no idea whatsoever of how change destination folder that's set in package. can somehow access installer variables preflight script? the idea have installing temp directory , moving stuff in post flight script, seems error prone , awkward. rule out possibility make installation paths editable (in case user has several instances of software we're plugging installed , picked wrong one). ...

which of following faster , why? cgfloat sum = 0; (uiview *v in self.subviews) sum += v.frame.size.height; or cgfloat sum = [[self.subviews valueforkeypath:@"@sum.frame.size.height"] floatvalue]; really, lot of how elegant (or clever) language comes down how avoids loops. for, while; fast enumeration expressions drag. no matter how sugar-coat them, loops block of code simpler describe in natural language. "get me average salary of of employees in array", double totalsalary = 0.0; (employee *employee in employees) { totalsalary += [employee.salary doublevalue]; } double averagesalary = totalsalary / [employees count]; versus... fortunately, key-value coding gives more concise--almost ruby-like--way this: [employees valueforkeypath:@"@avg.salary"]; kvc collection operators allows actions performed on collection using key path notation in valueforkeypath: . any time see @ in key path, denotes particular aggregate funct...

will code below execute in order? (i cannot put device-to-device copy of cudamemcpy2darraytoarray() in stream ) will code below execute asynchronously?

question: in postgresql ( using sql, not console ), how can list available datataypes ? ideally this: http://www.java2s.com/code/postgresql/postgre-sql/displaysalldatatypesintheconnecteddatabasewithcomments.htm it should list user defined types, if there any. list in pgadmin3 define datatype new column in table. "data types" in postgresql includes primitive (built-in) types, types added extensions, user-defined composite types, domains, , table rowtypes. isn't clear of these of interest you. types available in given database listed in database's pg_catalog.pg_type may need filter results. see the documentation pg_type system catalog table . types available not installed extensions not listed. there's no way list types provided extensions not installed in current database. to prettier listing of types use psql 's \dt * command. can see underlying sql executes running psql -e flag: $ psql -e regress regress=> \dt * ********* qu...

my software project based in canada , part of larger university research project. in process of cleaning code , asked add comments describing each class, method, etc. have been looking writing software license boilerplate each of class files. lot of templates have seen online gnu gpl don't think appropriate project since software commercialized. is there other licensing more suitable? have never written commercial software before not know kind of licensing type of code have. i think key thing need know owns copyright on code? belong or belong university? if belongs university, ask university point of contact guidance. if agreement university says retain rights code, put simple copyright notice in there, name , year. further, want consult job know kind of thing.

i'm bit miffed why this: cattr_accessor :aggregate { true } fails error: syntax error, unexpected '{', expecting keyword_end cattr_accessor :aggregate { true } ^ while same thing, do/end seems doing right thing: cattr_accessor :aggregate true end (but whhhay verbose ;) the source : http://api.rubyonrails.org/classes/class.html#method-i-cattr_writer bit crufty given time have spend on this. thoughts? isn't following language binding precedence? brace form has higher precedence , bind last parameter if invocation made w/o parens. do/end form has lower precedence , bind invocation without parens. if don't want write end form, need put parenthesis around call. cattr_accessor(:is_admin) { true }

what advantages of autowiring spring? an example of autowiring in spring like public class testclass { testmethod() { // ..... }; } public class mainclass { public static void main(string[] args) { applicationcontext ctx = new classpathxmlapplicationcontext("test.xml"); testmethod obj = (testclass) ctx.getbean("test"); obj.testmethod(); } } test.xml <bean id="test" class="testclass"> same in normal operation done using: public class mainclass { public static void main(string[] args) { testclass obj = new testclass(); obj.testmethod(); } } what advantage of spring, mean have heard terms inversion of control , dependency injection. in both examples reference of testclass used once through spring xml again through new oerator. can in simple terms explain advantage. autowiring in spring autowiring feature of spring framework enables inject ob...

i'm working on integrating current game engine irrklang sound engine, , dealing persistent error. simplified: fscore.h class fsengine { public: static fsengine *getinstance(); static void release(); ; private: static fsengine *instance; static fsbool exists; irrklang::isoundengine *soundengine; }; fscore.cpp #include "fscore.h" void fsengine::release() { exists = false; delete instance; soundengine->drop(); //c2227 }; the engine being declared correctly, , singleton performing expected. ideas? explanation of c2227 can found here: compiler error c2227 . when compiler gets line: soundengine->drop(); //c2227 it tells soundengine must pointer class / struct / union in order call drop() on it. actual problem here you're trying access non-static data member static function. also note delete doesn't changes value of pointer itself, after line executed: delete instance; the value of instance...

is there commonly accepted best practice maintaining configuration file available on client side (sort of equivalent of appsettings section on server side in asp.net application)? our application based on angular. our desire externalize environment-specific settings (like remote system urls, etc) code itself, ideally ops person , not developer can modify settings in 1 place. thanks in advance insight! i don't think it's idea use config.js file when developing angularjs apps. reason being, break possibility automatic testing. instead, create "settings" service in specify app specific context. example: angular.module('settings',[]).factory('settingsservice',function(){ var service={}; // insert settings here service.serverpath = 'whateverwhatever'; service.imagepath = 'bla bla bal'; return service; }); then inject settingsservice controllers need access settings. ofcourse, (which omitted simpl...

at moment i'm looking creating networked game using p2p. game not high paced , don't have access dedicated server, p2p seems choice me. have access online domain. programming done in c++. oblivious perils of game networking thought p2p did not need sort of centralized server communication. thought 'but how on earth can find other game users hosting game without knowing ip?'. thought need kind of central 'hub' game can connect list of available peer hosts ip , port. connect host , send data using udp (i know it's connectionless, seems enet has tricks that). if idea absurd, let me know. i had idea make simple php client-ip-switch-thingy on online domain. game won't attract more 2 3 people because it's personal learning goals load on domain won't of issue, think. problem can't find usable information on making of sort using php. tried through 'similar questions' bit of so, still can't find lot of info. my question is: how c...
