i trying run sample code book build watchos: develop , design. following segment of code returns 2 errors: @ibaction func buttontapped(){ if animating { spinnerimage.stopanimating() animating = false animatewithduration(0.2, animations: updatebuttontostopped()) } else { spinnerimage.startanimating() animating = true animatewithduration(0.2, animations: updatebuttontogoing()) } } both errors occur in calls animatewithduration() , indicate there type conflict. ideas of how can fix this? in hurry? instead of calling animatewithduration so: animatewithduration(0.2, animations: updatebuttontostopped()) you'd give updatebuttontostopped function parameter so: animatewithduration(0.2, animations: updatebuttontostopped) notice () after updatebuttontostopped gone. and same goes updatebuttontogoing of course :) why? if @ documentation animatewithduration ...

i'm working on inherited codebase uses posix message queues pass data between processes. because of nature of mq , messages have passed in form of bytes , numbytes passed along when messages reconstructed, there's lot of ugly static_cast<pvoid> -ing. question is there interprocess message passing interface in linux maintains datatype of content? or there better way of doing this?

i'm trying create hypermedia api in rails. i'd serialize payloads active_model_serializers using json_api adapter. doesn't seem trivial serialize links conditionaly. it's kind of blog application users can follow other users. when serialize user resource, usera, want have link rel :follow if current_user not following usera , link rel :unfollow if current_user following usera. seems extremely trivial use case when creating hypermedia api. know if there's way of doing active_model_serializers? i wrote (and include in serializers): def self.link(rel, &block) serializer = self super user = scope next unless serializer.can?(user, rel, @object) instance_eval(&block) end end # , in serializer (just usual): link :self api_user_path(object.id) end it work. don't feel right. , wouldn't surprised if future changes active_model_serializers screw things me. if else looking solution here did. ...

my code follows: namespace calculation { class program { static void main(string[] args) { console.writeline("this system calculate speed, distance or time."); console.writeline("1 = speed - 2 = distance - 3 = time"); console.writeline("please enter calculation perform. 1, 2 or 3"); string usercalculation = console.readline(); int calculation = int.parse(usercalculation); if(calculation < 1) { console.writeline("please enter number greater or equal 1 less 3."); } if (calculation > 3) { console.writeline("please enter number less 3 greater or equal 1."); } else { switch (calculation) { //this statement calculates speed. case 1: console.writeline("you have chose calculate speed. s = d/t"); ...
