scaling

问题 I currently am creating a horizontally scalable socket.io server which looks like the following: LoadBalancer (nginx) Proxy1 Proxy2 Proxy3 Proxy{N} BackEnd1 BackEnd2 BackEnd3 BackEnd4 BackEnd{N} My question is, with socket-io redis module, can I send a message to a specific socket connected to one of the proxy servers from one of the backend servers if they are all connected to the same redis server? If so, how do I do that? 回答1: As you wan to scale socket.io server, and you have used nginx

问题 We did some work on an app that lets people fire baseballs over the internet. It lives entirely within Amazon's AWS ecosystem, and we're building off that for a new project. The stack includes: -Dedicated MongoDB and Redis servers -three different groups of nodejs servers -additionally, we're making use of Amazon's API for server configuration and autoscaling The issue we're facing is that we haven't been able to simulate more than about 15000 concurrent users (websocket connections) per

问题 So far I have tried many ways of scaling images to screen sizes and none of them seem to work for me. I am still new to java and the idea of having a UI that fits to any screen size seems foreign to me. I am drawing bitmaps with the Canvas class. I have tried creating a scaledBitmap and have seen no difference. I want a simple main menu screen like this This must be a really common issue because all apps would need to do this. I really could use some help understanding how this works. On some

问题 I have used the following code to display miniature, live versions of other websites inside of one site: iframe { -moz-transform: scale(0.25, 0.25); -webkit-transform: scale(0.25, 0.25); -o-transform: scale(0.25, 0.25); -ms-transform: scale(0.25, 0.25); transform: scale(0.25, 0.25); -moz-transform-origin: top left; -webkit-transform-origin: top left; -o-transform-origin: top left; -ms-transform-origin: top left; transform-origin: top left; border: solid #ccc 10px; width:1024px; height:768px;

问题 i'm trying to build a webmap application in flex. for ths, 've got a fxg-file which represents the maps. it's in a also there are some elements, like POIs, text et cetera in this group. i zoom the with scaleX and scaleY, this works just fine for the map. but the problem is: ALL childen zoom also. i don't want this. they should stay the same place on the map and the same size. heres some code the as function <fx:Script> <![CDATA[ import mx.skins.Border; [Bindable] public var hoehe:Number = 1;

问题 I'm having some trouble scaling an image that i am inserting. I must be doing something wrong, because it does not change at all, no matter what i do. This is the code i have at the moment, but it does not seem to work. The image gets inserted fine, it just doesn't scale, no matter what values i try. Any obvious things i am doing wrong? Any common things that people do wrong? I am working in C#, but i assume the syntax is the same (more or less) in all languages. Image imgSpine = Image

问题 How do you make the iPad Pro app not scale when using Cordova? I figured out a workaround setting initial, minimum, and max scale to .75, but it still appears pixelated. When I look at the status bar on the home screen vs in the app, the app status bar is significantly larger, so I definitely know it's scaling up. 回答1: I figured that, since I couldn't find an answer to this on StackOverflow, I'd post my solution to the issue. I got assistance for this answer from http://www.cordovacircus.com

问题 Is there any solution for maintaining object size even if the user zoom in or out? I want to achieve like on the google maps behavior. So if I have an object (group of object) with a height and width of 20 even if I zoom into it, it should still be 20 pixels by default. Right now the behavior I have is that when the user zoom in or out the image gets bigger / smaller. I also did looping all the objects that I have on the canvas then set the scaleX and scaleY for it but the result was so laggy

问题 I am having a label in a view.After scaling the view, the label looks little blurred,the resolution is lost.How to retain the resolution after scaling. Here is my code for scaling secondView.transform = CGAffineTransformIdentity; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1.0]; secondView.transform = CGAffineTransformMakeScale(2 ,2); [UIView commitAnimations]; [self.view bringSubviewToFront:secondView]; 回答1: I set the ContentScaleFactor property of the label to

问题 The behavior I want to implement is to display a view at 1:1 scale by default. If its container is made larger (by the user dynamically resizing the parent JFrame) the view should be scaled to fit the larger area; if made smaller, the view should be scaled to fit the smaller area - up to a limit. When smaller than a minimum size, scroll bars should appear with a viewport to support navigating around the view which is displayed at its minimum scale. I have a poorly-functioning implementation
