node.js - Keep getting "socket.io/?EIO=3&transport=polling&t=Lvm1SGO" 404 errors when I deploy on server -


my app works fine on localhost once upload keep getting "socket.io/?eio=3&transport=polling&t=lvm1sgo" 404 errors keep listing in console. sorry if stupid question new socket.io. here can inspect , see error in action: http://95.211.186.223/projects/webrtc/work/p2pimage/

my client.js file:

// file meant browserified var p2p = require("socket.io-p2p"); var io = require("socket.io-client"); var ss = require("socket.io-stream"); var socket = io(); var opts = {autoupgrade: true, peeropts: {numclients: 10}}; var p2p = new p2p(socket, opts); var $ = require("jquery");  p2p.on("peer-num", function(num) {   console.log("you peer number " + num);   $(".peernum").html( "number " + num ); });  p2p.on("file", function(stream) {   //console.log(stream);    var img = document.createelement("img");   img.src = (window.url || window.webkiturl).createobjecturl(new blob(stream));   document.getelementbyid("receivedimages").appendchild(img); });  $(function() {   $("#file").change(function(e) {     ss.forcebase64 = true;     var file = e.target.files[0];     var stream = ss.createstream();      ss(socket).emit("file", stream, {size: file.size,name:file.name});     var blobstream = ss.createblobreadstream(file);     var size = 0;     blobstream.on("data", function(chunk) {       size += chunk.length;       console.log(math.floor(size / file.size * 100) + "%");     });     blobstream.pipe(stream);   }); });

my server.js file:

var app = require("express")(); var express = require("express"); var server = require("http").server(app); var p2pserver = require("socket.io-p2p-server").server; var io = require("socket.io")(server); var ss = require("socket.io-stream"); var path = require("path");  app.use(express.static(__dirname)); io.use(p2pserver);  var peernum = 0;   io.on("connection", function(socket) {    console.log("peer " + peernum + " connected");   io.emit("peer-num", peernum);   peernum++;    ss(socket).on("file", function(stream, data) {      var filename = path.basename(data.name);      var parts = [];      stream.on("data", function(data) {       parts.push(data);     });      stream.on("end", function() {       socket.broadcast.emit("file", parts);     });    }); });      server.listen(3000, function () {   console.log("listening on 3000") });

you problem trying contact nodejs server on apache server.

this this: description apache

the problem apache doesn't know how handle incoming socket.io request. simplest option expand server , let socket.io connect port: description apache , socket.io

so same before.

in example setup, have apache installed on dev server (like 1 mentioned). have access servers shell.

  1. transfer files holding express , socket.io files server (besides web root directory, not in /var/www. recommend put in /home/myusername/[productname]).

  2. make sure nodejs , npm installed on server

  3. if didn't transfer node_modules, execute npm install install packages.

  4. set port other 80 - 3000. remember number.

  5. start server on client (node index.js or similar)

  6. if access server know via port 3000 (http://myserverdomainorip:3000) should same results on client. want (or have) use apache web server. open in apache web files file starts socket.io client. there should line around this: var socket = io();. change socket.connect('http://myserverdomainorip:3000');

so static files serverd on apache, socket.io connection established nodejs server.

i hope understand bit right know. apache , socket.io bit complicated.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
