问题 I've got a Rails application, and am looking to add some sort of WebSocket support to it. From various googling, it appears that the best Ruby based WebSocket solution is em-websocket running on EventMachine. I was wondering if there was a way to "integrate" an EventMachine reactor into Rails? Where do I put the initialization code? Is this the proper way to accomplish this? I've seen this example that falls back on Sinatra to do an EventMachine GET request, but that isn't quite what I'm

Just installed El Capitan and can't install gem eventmachine 1.0.7 . openssl is at 1.0.2a-1 . Tried to use --with-ssl-dir but it seems ignored. Reported it to their github repo as well. Any suggestions are really appreciated. Thanks. $ ls /usr/local/Cellar/openssl/1.0.2a-1/include/openssl/ssl.h /usr/local/Cellar/openssl/1.0.2a-1/include/openssl/ssl.h $ gem install eventmachine -v '1.0.7' -- --with-ssl-dir=/usr/local/Cellar/openssl/1.0.2a-1/include /Users/pain/.rbenv/versions/2.1.2/bin/ruby -r ./siteconf20150612-56154-1hsjz2n.rb extconf.rb --with-ssl-dir=/usr/local/Cellar/openssl/1.0.2a-1

问题 I have been using Sinatra for sometime now and I would like to add some realtime features to my web-app by pushing the data via websockets. I have successfully used the gem 'em-websocket' on its own, but have not been able to write one ruby file that has a sinatra web server AND a web-socket server. I've tried spinning the run! or start! methods off in separate threads with no success. Has anyone gotten this to work? I want to have them in the same file as I can then share variables between

What is the difference between event driven model and reactor pattern? [closed]

问题 From the wikipedia Reactor Pattern article: The reactor design pattern is an event handling pattern for handling service requests delivered concurrently to a service handler by one or more inputs. It named a few examples, e.g. nodejs , twisted , eventmachine But what I understand that above is popular event driven framework, so make them also a reactor pattern framework? How to differentiate between these two? Or they are the same? 回答1: The reactor pattern is more specific than "event driven

Peer-to-peer file sharing with Web Sockets

问题 This is sort of a theoretical question, however, I need to add file sharing capabilities to my web socket powered chat application. I could use a service like Amazon S3 to upload a file to share by posting a link to the file, but that involves the uploading of a file that may already be accessible over the local network (sharing a file between co-workers for example). So I had the idea that it might be possible to somehow tunnel the upload/download/transfer through the already existing web
