问题 I am developing a simple informative system which will use a lot of images. The problem is I do not know how to scale them to the folder of ldpi, mdpi, hdpi, and hdpi. I read that android uses a scaling ratio like 3:4:6:8. Can some explain to me what is this 3:4:6:8 scaling ratio ? How do I use it, and what is the logic behind it? Suppose I have a 50x50 px image in ldpi folder. If I am going to use 3:4:6:8 ratio . What will be the next image size for my mdpi folder and hdpi folder? Please

问题 Ok, I'm trying to get a div to scale and the height is always the height of the viewport. I'm going to link to my examples as it needs some explaining. www.madmediablitz.com/tv/precentdemo.html The link above is the closest I've come to a solution and I'm hoping that someone here will find it simple to fix. What I want to happen is the tv to always be the height of the viewport (to a degree, min-height:~400px; max-height:~700px;). The code that I used there is based on http://www.alistapart

问题 I am unable to understand the page of the StandardScaler in the documentation of sklearn . Can anyone explain this to me in simple terms? 回答1: The idea behind StandardScaler is that it will transform your data such that its distribution will have a mean value 0 and standard deviation of 1. In case of multivariate data, this is done feature-wise (in other words independently for each column of the data). Given the distribution of the data, each value in the dataset will have the mean value

问题 I'm using a picturebox to create a visual of an instance of my truss class. I'm creating the visual by drawing directly onto the picture box in the paint event. The method looks like this private void pictureBox1_Paint(object sender, PaintEventArgs e) { if (isDraw) { //Preparing to draw Graphics g = e.Graphics; g.SmoothingMode = SmoothingMode.AntiAlias; g.InterpolationMode = InterpolationMode.Bicubic; RunEntry entry = this.passedHistory.SelectedItem as RunEntry; AnsFile objToDraw = entry

问题 Suppose I have an Azure role with three instances running. I ask Azure to change the role count to two either by Management Portal or via Management API. How will Azure decide which role to take down? 回答1: As British Developer mentioned, the Windows Azure Fabric Controller decides which instances to shut down. You cannot control this process. I don't think it is always the last number, because I am not sure whether the fabric controller does not rename the instances after shutting down. So

问题 Changing an ASP.NET MVC synchronous controller ( Controller ) to an asynchronous controller ( AsyncController ) seems like a trivial thing to do, but when should you do it? Should I just make every controller async irrespective of its actions? What are examples of operations that would be improved if used in an asynchronous controller? Taking the most trivial example: static html pages. So you have the most basic of controllers which simply returns a View from the Index action. Should this
