my question straightforward. why works: public delegatecommand logincommand { get; } func<bool> canexecutelogin = () => !stringservice.isnullorempty(_entries.logintext, _entries.passwordtext); logincommand = new delegatecommand(onlogintapped, canexecutelogin); but doesn't: public delegatecommand logincommand => new delegatecommand(onlogintapped, () => !stringservice.isnullorempty(_entries.logintext, _entries.passwordtext)); i check so: public string loginentrytext { { return _entries.logintext; } set { _entries.logintext = value; logincommand?.raisecanexecutechanged(); } } doesn't work, mean func never executes after initialization. question not entirely clear me, suspect reason follows. this public delegatecommand logincommand => new delegatecommand(...) is equivalent this public delegatecommand logincommand { {return

abstract class intset { def contains(x: int): boolean def incl(x: int): intset } i'm learning scala. why return type of method incl class name intset ? mean? usually logic , functional programming languages declarative (not per se enforced, in cases, declarative style advised). means not alter datastructure : construct new 1 modified original one . in declarative language when have intset , add element, not add intset , construct new intset has elements of original intset , 1 add x . so reason why incl returns intset because original intset not modified, constructs new one. usually when new intset constructed, of course not construct complete new object . since orignal intset not supposed change, can use sub-structures of original intset . therefore declarative languages have own set of dedicated data-structures, instance finger tree . take instance this implementation of intset . see is: object empty extends intset { override def tostrin

why need separation between kernel space , user space, when every data structure, every memory resource managed kernel if create process in user space? why need such big architecture? all page tables, context switching etc. managed kernel, why user space? can not use 1 space , develop things on it? this question may sound weird, want understand why required? if have design new os , not perform such division between kernel space , user space, problem? thanks if there no protection between kernel space , user space or between different user processes can write code intentionally or accidentally modify either memory in kernel space or memory in space of user process. old ms-dos lacked protection.

want parse google news rss javascript. managed run code in php code form how parse google news in php : my question how can same thing in javascript code example parse: http://news.google.com/news?pz=1&output=rss&cf=all&topic=topics&q=obama&hl=en&num=10 , data different news there thanks. the data obtained in xml format. you can access items using domparser . see: xml parser example parser = new domparser(); xmldoc = parser.parsefromstring(data,"text/xml"); var items = xmldoc.getelementsbytagname('item') console.log(items); 📝 working example // [1] parse xml feed array of js objects function parsedata(data) { parser = new domparser(); var xmldoc = parser.parsefromstring(data,"text/xml"); // convert collection array // getelementsbytagname returns collection/nodelist instead of array. // more convenient if use array. var items = array.from(xmldoc.getelementsbytagname('item')); var
