measure

问题 I have a web service that receives data in JSON format, processes the data, and then returns the result to the requester. I want to measure the request, response, and total time using cURL . My example request looks like: curl -X POST -d @file server:port and I currently measure this using the time command in Linux: time curl -X POST -d @file server:port The time command only measures total time, though - which isn't quite what I am looking for. Is there any way to measure request and

问题 I created a custom view to display a gameboard for a game I'm developing. The gameboard needs to be a square at all times. So with and height should be the same. I followed this tutorial to achieve this. I added the following code to my custom view: @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); int width = getMeasuredWidth(); int height = getMeasuredHeight(); int widthWithoutPadding = width -

问题 I am trying to create a calculated member to calculate the nb of employees YTD. By YTD I mean the number of employees for any given period of time.My fact table has 2 date dimensions StartDate and EndDate. I would like to calculate YTD employees as follows. Members with StartDate equal to or before current period AND EndDate in the current period OR EndDate is NULL 回答1: I had a similar task and end up with the following solution: SUM( [EmployeeChanging].[EmployeeChanging].[EmployeeChanging]

问题 I want to be able to find the length of a path in a picture, this could be the length of a worm, a curly human hair, Amazon river, etc. Consider this Amazon river picture: I tried to make an skeleton of my picture after its binarization, but the problem is that the skeletons (obtained by two methods) have many small branches that causes their area to be much more than the approximate length of the path. I used scikit-image to do this. Here's the code and results: from skimage.filter import

问题 I am working on a C++ game / simulation / graphics application on Windows. (edit start) If it matters, I am using Visual Studio 2013. (edit end) Setup: I am measuring the time from one frame to the next using QueryPerformanceCounter(). Steps to Reproduce: Stop at a breakpoint for some debugging. Current Undesired Result: When application resumes execution, the next time QueryPerformanceCounter() is called, it will return a time value that includes all of the time was spent paused at the

问题 I have a WebView and a native custom view I want to add underneath the WebView . I've tried wrapping the WebView inside a ScrollView , and while that does exactly what i want, the scrolling performance is really laggy and if a user flings the scroll tapping the screen does not stop the fling like it should. The other approach I was thinking was to inflate the WebView into a wrapper FrameLayout with my footer view on top of the WebView , then somehow extend the WebView height to accomodate the

问题 I'm trying to measure a view using a ref , but the width returned is 0 despite the fact that I see the view displayed on the screen (and it's far from being equal to 0). I tried to follow this : https://github.com/facebook/react-native/issues/953 but it just doesn't work ... I just want to get the actual width of the View. Here is my code : var Time = React.createClass({ getInitialState: function() { return({ progressMaxSize: 0 }); }, componentDidMount: function() { this.measureProgressBar();
