问题 I'm in the process of building a complex web app that must work a lot with real-time data and showing that data to the user. Given that I'm more used to Rails, I'm wondering if there's a big advantage of dumping rails and use node.js to build the app or if there's a way I can have the real-time advantages of Node.js in Rails. Better would be to be able to use Node.js and Rails. Is that a possibility? Thanks 回答1: Better would be to be able to use Node.js and Rails. Is that a possibility? IMHO

问题 I'm going to develop a WhatsApp like IM app. I'm looking for something that gives me the most pre-cooked solution. I've used sockets before in a Webapp for similar purposes and have heard that XMPP(it's implementations) is widely used for this sort of work. Considering the choices at hand I understand XMPP will be the way to go but I have the following questions: Why Should I use XMPP (How much will I have pre-cooked?) Why Can't I use sockets? though they seem to be very easy to work with and

问题 I wanted to know if I get different results in New Relic real time user monitoring when many users are logged into the application concurrentky? Or the only way to achieve that is to use a load testing tool? 回答1: You will likely see different results when more people are using your site at once. The JavaScript injected for Real User Monitoring (RUM) collects timing information in the browser that contains details to identify the specific app and the web transaction processed on the backend,

问题 so I have this real-time game, with a C++ sever with disabled nagle using SFML library , and client using asyncsocket, also disables nagle. I'm sending 30 packets every 1 second. There is no problem sending from the client to the server, but when sending from the server to the clients, some of the packets are migrating. For example, if I'm sending "a" and "b" in completly different packets, the client reads it as "ab". It's happens just once a time, but it makes a real problem in the game. So

问题 Can we use gevent.sleep() anywhere in our application or gevent.monkey.patch_time() on any third party libraries without an issue, especially precise timings takes place? For example, some libraries use time.sleep() function in order to measure a couple of microseconds that is used to control an embedded (dot matrix LCD and such) device. Can we safely monkey patch such libraries without a problem? 回答1: No. gevent.sleep() is not suitable for precise timings. Here is the test code: import
