modifier

I would like to measure the computing time of methods. A nice way is ( How do you performance test JavaScript code? ) with console.time('Function #1'); and console.timeEnd('Function #1'); My idea is to add these console outputs on lifecycle-methods. In this case using SAPUI5 like createContent:funtion(){}; methods. This should be possible with AOP using before() and after() to runt the time counting. Which AOP framework would you suggest and how to implement it with the need of modifying the identification string "Function #1" automatically? There actually is no need for aspects in Javascript

Today, I found something in legacy code. It has "static new" for one function. It looks like this. class Foo { public static void Do() { Console.WriteLine("Foo.Do"); } } class Bar: Foo { public static new void Do() { Console.WriteLine("Bar.Do"); } } I don't understand the static new modifier for the Do method in class Bar . In C#, static method can only be invoked with class name instead of object name. So, I don't think there is any difference between having the "new" and not. Generally, if some syntax is unnecessary, C# just treat it is error. Anybody has any idea about why C# allows such

First, before I go on, I have read through: SceneKit painting on texture with texture coordinates which seems to suggest I'm on the right track. I have a complex SCNGeometry representing a hexasphere. It's rendering really well, and with a full 60fps on all of my test devices. At the moment, all of the hexagons are being rendered with a single material, because, as I understand it, every SCNMaterial I add to my geometry adds another draw call, which I can't afford. Ultimately, I want to be able to color each of the almost 10,000 hexagons individually, so adding another material for each one is

This question already has an answer here: Warning: preg_replace(): Unknown modifier ']' 3 answers <? php $Src = 'images/pages/clients/logos/clnt_aljareera_img.jpg'; $pttn= '/&Src:'.$Src.'/'; $string=preg_replace($pttn,'',$string,1); ?> //output Error: Unknown modifier 'p' in Your string contains a whole mess of / which would need to be escaped as \/ when using / as the regex delimiter. Instead of / as the regex delimiters, use something which won't occur in your string like ~ for example. You must choose a delimiting character which is guaranteed not to appear in $Src , however. You might be

I'm self-answering this question because I've seen it asked all over the Internet, but with few helpful answers, and definitely no resolutions on Stack Overflow that I can find. Example Code Consider this code, which simply writes several lines of shell commands: ^0:: SetKeyDelay, 0, 0 myWindow = ahk_exe Notepad.exe ControlSend, , set c=".cshrc-andrew.cheong"`n, %myWindow% ControlSend, , set v=".vimrc-andrew.cheong"`n, %myWindow% ControlSend, , foreach d ( /userhome/andrew.cheong /home/$USER /data/$USER )`n, %myWindow% ControlSend, , if ( -e $d/$c ) source $d/$c`n, %myWindow% ControlSend, , if

I've learn C++ for some time, however there is always this question which puzzles me (for years). In school, our lecturers like to declare class variables as private. In order to access it, we have to declare an accessor to access it. Sometimes we even have to make the different classes become "friends" into order to access its elements. My question is: Why make it so troublesome? What is the true rationale behind all the private and protected stuff when we can just make our life as a programmer easier by using public for everything? I was thinking, once the code gets compiled, the end user
