I'm interested in building a text chat application along the lines of AIM, facebook chat, etc, and I'm wondering where a good place to start would be.
Thanks!
One word. XMPP.
I've written a chat client with both server and client parts in Java, and our company uses one based in Delphi, so I would recommend either of those.
If you use Java, I would recommend using EclipseRCP to create a GUI quickly, and Delphi is already great for GUI's with it's forms.

I am new in Multiplayer Game Development, I have already developed a offline game and now I want to make it a multiplayer, so with help of my friend we create a server side script in node.js, but I don't know how to integrate this in my c++ project,
I've googled but, can't find anything helpful.
anybody can suggest any tutorial.
Thanks
You've asked a big open-ended question. As Allern suggests there are a lot of things that you can do with networked programs that can extend it well beyond that of a single user game. For instance in my current game there is an access to a version welcome page in html. There are file downloads for campaign/user maps and there are connections to Firebase for leaderboards and other networked resources like ads.
However, I suspect you are referring to the communications between a number of separate user machines all synchronized to keep them coordinated. For this you will need to write some serialization code to transmit to and receive packets from the central server. Typically a serialization package like flatbuffers will be needed to move information from your data structures to a packet and the reverse.
You might also require communication/network software to asynchronously send and receive those packets (this may be included in whatever game engine you might be using). Boost.asio might help otherwise. There are numerous other networking packages and libraries all the way down to the bare-bones unix/POSIX calls (or Windows OS calls).
You will also need software on the server side to log users in, deal with players disconnecting and doing the main work of passing the game packets around. This software may also implement the logic of your game (game rules) and might do saves on the data if you want users to be able to play the game in multiple sessions (like a big dungeon crawl). There might be packages out there that do most of the server side stuff. If so, please post what you find out.
Cocos2dx does have some networking software built in but it isn't very functional as far as I'm concerned. It does have facilities to display web pages and download files fairly easy but the async communication seems a little weak. You can try the Network module in the API Docs which may have what you are looking for.
Since the type of game and how you want to implement your player interaction will dictate how the software is to be built I'm afraid this answer is a little vague. Good luck. Share your insights.
you can use public tools , as a sample is websocket,it can support C++ and javasc
I want to apologize about my English. It's not very good.
So, I want to make a chat application (pretty much like Facebook's), and after reading a lot I decided to make this chat app with Erlang. After more reading I found out that I can use Yaws server to make a web application with Erlang, but that's all. I still can't even install and configure it well. So my questions are:
Is this information correct? Do I need Erlang / Yaws to create this chat app?
If it's correct, how do I install and configure it under Windows 7? I've tried to simply install "OTP 17.0 Windows 32-bit Binary File" from here http://www.erlang.org/download.html and "Yaws-1.98-windows-installer.exe" from http://yaws.hyber.org/download/, but I think something went wrong, because after I "configure it" at localhost port 8001/8080 or others still nothing happens. So what's next? Do I have to install my code in special directories and/or what do I have to do next ?
In case I finally get a Chat application in Erlang ready, how can It interface with my PHP code? I mean, I already have the PHP project. It is a normal web project with PHP/HTML/Javascript, etc. so my question is, how do I glue these two elements together?(I would like to stress one more time that I have to make something like the Facebook chat).
I'll be thankful for all kind of information, tutorials, books, videos, anything.
I agree with you, Erlang is an excellent option for a chat server. If you want to go for Yaws, check the documentation, it support external scripts via CGI and Websockets. All the information you need to communicate your PHP application with your chat Application is on chapter 9 of yaws' pdf documentation.
There are many ways to create a web application in Erlang. Here are some old examples that use mochiweb:
http://pragprog.com/screencasts/v-kserl/source_code
http://www.chrismoos.com/2009/09/28/building-an-erlang-chat-server-with-comet-part-1/
and a nice example from erlang central
Regarding the PHP integration,there are again, several ways to communicate both. You can integrate the chat with your PHP code using a PHP Erlang bridge
or using websockets
or probably you could try to send your data encoded in JSON from mochiweb using mochijson2.erl and communicate both by HTTP using curl from PHP.
All in all, I would probably also use yaws since is well documented and easy to use. Good luck
I'm in the planning stages of a web app that is intended to help children learn vocabulary. We would like to make the app as interactive as possible. For example, we would show a picture of an apple and ask the child to identify the object. The child would then say "apple" and we would determine whether they are correct, etc.
The new Web Speech API seems like a promising tool for this project. However, looking through the documentation, I believe it will only produce transcripts from speech (i.e. it cannot match a spoken word to a known word and produce a confidence value – at least not out of the box).
Does anyone have experience with leveraging the Web Speech API in this way (or any other API for that matter)? I'm trying to stick to technologies that can run in the browser, if possible.
Try ispikit.com, it's way more suitable for your needs, it's specifically designed for education tasks and works in a browser on a client side. Web Speech API is not designed for detection, so you will not be able to use it.
I'm a node.js starter.
The product I want to deliver looks like online chat with 1000+ participants at a time.
I'm looking for a cross-browser demo (IE7, android support) to start with.
The thing I worry about is client side cross browser part. I dream about a library that uses web sockets for supported browsers and iframe for not supported, is well tested, and encapsulates COMET realization.
I have found some solutions in the web, but I'm qurious about your advices.
Thank you
I like to use socket.io which is a quite elaborate tiny library for handling such things. Maybe you want to give it a try as well ;)
I've currently found https://github.com/maccman/juggernaut the best solution. I will come back here in a month and tell about my experience
I want to go learn web programming,but besides names and a little of html I don't know anything.So I ask you what programming languages you recommend,why,what can be done with it,tools to learn ,etc.I don't know if it matters but I program in a Linux enviroment(Ubuntu).
I don't want to do hardcore web programming ,I only want to be able to develop complete websites and understand network concepts.
Well, most cheap/free web hosts support PHP, MySQL, and most browsers support Javascript.
Target those and you'll be on a reasonably good path.
Some support Ruby and Python, and you might choose that path if you want to learn those languages.
Good luck!

Definitely start with HTML, and basic CSS. These are the core of web programming, and you need to understand them well to do anything of consequence.
Once you've got those down, you'll want to move on to a server-side language. The easiest is PHP, but be careful of picking up bad habits, since it's a loose environment; if you stick with PHP, you'll eventually want to use it with an MVC framework such as CodeIgniter, which encourage separating presentation and logic. To get a little more advanced, you can also try Python or Ruby. Get yourself some server space to mess around with; most shared hosting plans are $5-10/month.
For Javascript/AJAX, you'll probably want to start by using Firebug or Firefox's DOM inspector to learn the relationship between the HTML of a page and the DOM object which Javascript uses to interact with it. Once you understand how the DOM works, toy around with jQuery to start doing useful (and fun!) stuff.
You'll also eventually want to learn MySQL (or a similar SQL variant), but that can probably wait, since you can do lots of interesting things without tackling database stuff.
Above all, be patient and persistent, and make use of every resource at your disposal: books, Google, Stack Overflow, and cheat sheets.
Ruby all the way. It's exactly what you need if you're interested in web dev and completely starting from scratch programming-wise. From the basics of Ruby it's pretty easy to get into Rails, which is a very beginner-friendly web framework.
Many great books on Amazon (look for the highest rated of course) on both Ruby and Rails.
Great starting point for links:
http://www.ruby-lang.org/en/documentation/
As well check out Learn to Program
Now get learnin'.
Google App Engine offers free hosting for applications that do not exceed the specified limits. The server-side language is Python, the client-side language is JavaScript inside Django templates. Everything has worked nicely for me in Ubuntu 8.10.
GREAT Question,
a couple of years ago I was in the same place -
What HONESTLY Helped me was using Dreamweaver, I set it in split mode and started watching the code
I used this and started delving into the PHP Application world and could see what was going on (sort of)
I know you can use dreamweaver with wine on the linux, and it can help you do a TON
granted if you continue it has the potential to limit you to the dreamweaver world... but can help you learn and create at the same time
(I build full php apps from scratch now with a notepad... but I started with DW)
The question I'd have is what kind of scale on web programming are you wanting to do? If it is small stuff then the LAMP stack would be my suggestion while if you want to get more into 3-tier architecture then Java or ASP.Net may be worth getting into for middleware or business logic code.
With the exception of the reference to the LAMP stack above, there has been no Perl recommendations. I like Perl as it is easy enough to build a fairly full featured web application (using CGI, or mod_perl). Of course, you are going to have to learn HTML/CSS if you are going to do anything on the web. I feel Perl is a good choice for web development as it is fairly robust and full featured with all of the modules available on CPAN. Combine with an application framework like CGI::Application or Catalyst and you can build sophisticated web apps in a short amount of time. Also, using a tool like XAMPP can help as you won't have to worry about web server or database cofigurations to get started.
