What is prefered way to loop in Ruby? -

-

Why do each loop in ruby ​​ like for loop? Is there a difference in the complexity of time or are they just different sentences than creatively?

Yes, they are two different ways but to walk again, but hopefully in this calculation Helps. 

  'Benchmark' is required a = array (1..100000000) yoga = 0 benchmark. Timetable {a.each {| X | Sum = = x}}   
 This takes 5.866932 seconds  
  a = array (1..100000000) sum = 0 benchmark. Real time {sum in x = = x end}   
 it takes 6.146521 seconds.  
 Although this is not the right way to do benchmarking, there are some other obstacles but on a machine, it looks a bit faster than each one.

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
