i attempting serialize class xml , have properties serialized attributes of class, rather nested node. using webapi automatically handle serialization of xml. this class: [datacontract (namespace="", name="attributetest")] [serializable] public class attributetestclass { [xmlattribute("property")] [datamember] public int property1 { get; set; } } here output receiving (note property1 not attribute in spite of being decorated [xmlattribute] ): <attributetest xmlns:i="http://www.w3.org/2001/xmlschema-instance"> <property1>123</property1> </attributetest> this output want receive: <attributetest property1="123" xmlns:i="http://www.w3.org/2001/xmlschema-instance"> </attributetest> what missing? i'm not familiar webapi output receive looks it's serialized using datacontractserializer , not xmlserializer need. check if adding following application_

i have function, y = 50sin(x/50) + 100. want draw curve function, without additional info graph plotters, need wave on screen. x should correspond x parameter of screen , y y parameter of screen. here code of current view. public class sinusoid extends view { paint paint = new paint(); public sinusoid(context context) { super(context); paint.setcolor(color.red); } @override public void ondraw(canvas canvas) { //todo draw line using myfunction } private double myfunction(double x){ return 50 * math.sin(x / 50) + 100; } } now question is, should fill in todo? please help, documentation or example useful. thanks in advance. the idea have this: @override public void ondraw(canvas canvas) { (int x=0; x<canvas.getwidth();x++) { canvas.drawpoint(x,(float) myfunction(x),mpaint); } } but you'll need adjust value of function given canvas height.

unfortunately haven't found official resource on this. is allowed use ternary operator this, shorten , if/else statement: (isset($somevar) ? $this->setmyvar('something') : $this->setmyvar('something else')); in php documentation, ternary operator explained example: $action = (empty($_post['action'])) ? 'standard' : $_post['action']; this makes me believe use case might work, not valid because setter function not return anything. yes, can. php doc : [...] ternary operator expression, , [...] doesn't evaluate variable, result of expression. that quoted, although ternary used assigning values, can use suggested because function call expression appropriate function evaluated (and therefore executed). if setter function return value, not assigned , therefore lost. however, since said setter doesn't return anything, whole ternary operator evaluate nothing , return nothing. that's fine. if more

i've written c code - below - have benchmark of functions. main purpose of benchmark test these functions on avr @ tiny85, on pc (for i'm using atmega168 instead of @ tiny85 - same). this benchmark executes big number of loops each function has test , "void" function receives same parameters of function tested, executes return. @ end of loops of each functions writes label , time expressed in usec. time duration of loops function specified label. i might think if subtract benchmark time of "void" function benchmark time of function tested , divide result number of loops, i've sufficient information duration of function tested. not true because interrupts (even measure time). in case think benchmark able indicate me fastest function. what's opinion? have suggestion about? here output example: void 2110168 norm 2121500 base 2337196 basl 2450964 basw 2333980 ant4 2235236 ant5 2242904 unro 2270484 unrl 2590444 vect 2754188 vesw 2732472 th

wanting take fixnum of integers , multiply even(indexed) integers two. figured best way first turn fixnum array. lets following number of 16 digits: = 4408041234567901 i know could: a.to_s.split('') which return 'a' array of 'stringed' numbers. cant follow with: a.map!.with_index {|i,n| i.even? n*2} guess i'm kinda stuck on how create method this. question may how turn group of numbers array of fixnums/integers instead of strings. to change array, do a = 4408041234567901 arr = a.to_s.chars.map(&:to_i) # => [4, 4, 0, 8, 0, 4, 1, 2, 3, 4, 5, 6, 7, 9, 0, 1] you can multiply alternate numbers 2 arr = a.to_s.chars.map.with_index {|n,i| i.even? ? n.to_i * 2 : n.to_i } # => [8, 4, 0, 8, 0, 4, 2, 2, 6, 4, 10, 6, 14, 9, 0, 1] improving little bit, can use hash find number multiplied. h = {true => 2, false => 1} a.to_s.each_char.map.with_index {|n,i| n.to_i * h[i.even?]} edit i can explain each step, better if can
