it seems in november, apple updated both nsmanagedobjectcontext class reference , core data programming guide documents explicitly bless serial gcd dispatch queues , nsoperationqueues acceptable mechanisms synchronising access nsmanagedobjectcontext . advice seems ambiguous , possibly contradictory, , want make sure i've understood properly. previously accepted wisdom seemed nsmanagedobjectcontext accessed thread created it, , using serial queue synchronisation not sufficient; although serial queues perform 1 operation @ time, these operations can potentially scheduled on different threads, , moc doesn't that. but now, programming guide, have: you can use threads, serial operation queues, or dispatch queues concurrency. sake of conciseness, article uses “thread” throughout refer of these. so far, (although conflation of threads , queues unhelpful). can safely use single context per (serial) queue, instead of 1 per operation/block, right? apple has visual dep...

what difference between null , "" (empty string)? i have written simple code this: string = ""; string b = null; system.out.println(a==b); // false system.out.println(a.equals(b)); // false and both statements return false . seems, not able find actual difference between them. "" actual string, albeit empty one. null, however, means string variable points nothing. a==b returns false because "" , null not occupy same space in memory--in other words, variables don't point same objects. a.equals(b) returns false because "" not equal null, obviously. the difference though since "" actual string, can still invoke methods or functions on like a.length() a.substring(0, 1) and on. if string equals null, b, java throw nullpointerexception if tried invoking, say: b.length() if difference wondering == versus equals, it's this: == compares references, if went string = new string(...

i'm @ point i'm ready submit app - apple doesn't elaborate on how sign , submit apps. have both wwdrca certificate , 1 created @ loss on put them.. add them via drag n' drop xcode? why need wwdrca? have info on this? appreciated first, make sure have correctly installed installer, developer , wwdr certs in keychain. in xcode, edit target build settings , under 'code signing entity' , select developer certificate. build app using 'build , archive'. finally, open organizer (via window menu) verify , submit app. at least, that's theory. agree it's tricky. apple developer forums have several instructive postings potential pitfalls. luck!

how can customize joomla main menu this: http://www.ruckuswireless.com/ that's not going quick , easy hack, might able pull off html override. if want close, can close 1 of mega menu extensions. if want hack yourself, need copy of joomlainstall/modules/mod_mainmenu/tmpl/default.php , put in joomlainstall/templates/yourtemplate/mod_mainmenu/default.php once have made modifications. you can use menu item image image @ top of dropdown. menu description little trickier, menu systems use menu title purpose. when put in title need separator can split title in the title , description. format have menu title|menu description. this pretty big modification general idea.
