chat

I've seen other topics like this: launch facebook app from other app and tried some of the URIs listed there, but I can't figure out how to start the facebook chat with a specific friend. Is there an official page that describes the IntentUriHandler and all the allowed URIs with their params? Thanks, Lorenzo tasomaniac found it here: https://developers.facebook.com/docs/messenger-platform/discovery/m-me-links#format http://m.me/{#user_id} you can use this URI to open messaging with a friend with known id. You can start the intent like below startActivity(new Intent(android.action.VIEW, "http:/

Can someone please provide me with Nginx configuration for the Tornado websocket chat demo? the demo is located under /tornado/demos/websocket... A config like this will work: events { worker_connections 1024; } http { upstream chatserver { server 127.0.0.1:8888; } server { # Requires root access. listen 80; # WebSocket. location /chatsocket { proxy_pass http://chatserver; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } location / { proxy_pass http://chatserver; } } } You'll need to run Nginx as root in order to listen on port 80. Now

I'm interested in creating what Disqus have done with their commenting system: http://highscalability.com/blog/2014/5/7/update-on-disqus-its-still-about-realtime-but-go-demolishes.html The most impressive part of infrastructure is Nginx push stream module: Still runs on 5 machines Nginx machines. Uses NginxPushStream, which supprts EventSource, WebSocket, Long Polling, and Forever Iframe. All users are connected to these machines. On a normal day each machine sees 3200 connections/s, 1 million connections, 150K packets/s TX and 130K packets/s RX, 150 mbits/s TX and 80 mbits/s RC, with <15ms

1. 数据采集之Flume Taildir Source 相当于exec + spool的功能，还有断点续传功能。Flume1.7版本以上才有此功能，可以监控一个目录，并且根据正则表达式对目录中文件名对文件进行实时收集。 注意1：当只以文件大小的方式进行滚动，如果文件不满足条件，会永远处于临时状态。 解决办法1：停止Flume（不推荐） 解决方法2：设置参数：hdfs.idleTimeout，当文件不满足滚动条件的时候，文件在一定时间（hdfs.idleTimeout）内没有任何操作，此时让其执行滚动。 注意2：Flume设置某一种滚动方式，在满足条件后，文件滚动到了第一个datanode后，还需要向其他副本复制，这个也是需要花费时间的，默认是当每个副本都复制完Flume才会认为完成，这时候Flume就会还认为没有写入成功，会继续传递数据。 解决办法：设置参数hdfs.minBlockReplicas=1,这时候Flume就会认为检测到只有一个副本，只要一个写入成功就会认为成功，其他的复制过程还是由hdfs完成。 2. 模块开发之数据预处理 根据目标制定规则，过滤掉“不和规定”的数据，清洗无意义的数据。 a. 实现方式:MR 一般字段比较多，这时候我们会封装成javabean对象，有了javabean对象我们就还要实现writable序列化接口

I've been trying to build a web based chat application for the past three weeks and i'm facing issues with whatever route (programming technique/technology) i take to build it. I've explained the issues i've experienced with all of'em below. Kindly provide whatever insights you have in this. ASP.NET-AJAX First issue is that it is Not Really Real Time If client hits the chat server every x seconds (constant time stamp) it is not going to be real time unless x is very very less If x is very small like 1 second and if there are 1000 users online at the same time i think it is really going to

I'm learning c# socket programming. So, I decided to make a TCP chat, the basic idea is that A client send data to the server, then the server broadcast it for all the clients online (in this case all the clients are in a dictionary). When there is 1 client connected, it works as expected, the problem is occurred when there is more than 1 client connected. Server: class Program { static void Main(string[] args) { Dictionary<int,TcpClient> list_clients = new Dictionary<int,TcpClient> (); int count = 1; TcpListener ServerSocket = new TcpListener(IPAddress.Any, 5000); ServerSocket.Start(); while
