I'm having troubles with finding tutorials/examples of how a simple VoIP application would look like. I've searched the web and found an out-dated step-by-step tutorial, so it wasn't much of a help and that's about it considering tutorials. However I've managed to find some nice API's like libosip ( oSIP ). It would be a great thing if anyone would know any good tutorial; or if anything a small VoIP open source app that i could checkout. I don't really have any troubles with understanding someone else's code if it wasn't commented/explained.
There is a great sip framework called PJSIP. look at this example for a short, but yet complete demo. Also take a look in the PJSUA API.

I recently learned about django-discussion. I don't know it may be a great application but I couldn't find any documentation, no example anywhere on the web.
Can somebody please guide me to the right direction? How can I integrate it with other application?
According to the lists of django forum applications here and here, there are better alternatives like django-threadedcomments, djangobb or pybbm - take a look.
Plus, django-discussion is not actively developed now.
Hope that helps.
For some time now I've been tossing around what I think is am awesome idea: I want to write essentially a C++ phone server to handle all of my incoming calls on a land-line. I'll have a white-list (yay never having to worry about telemarketers ever again!), a black-list, and will be able to access my phone using my gaming headset, allowing me to make/answer calls while I'm gaming or whatever. In the future I'd also like to hook it up to a gui and make it have pop-ups and other cool features.
The problem is, I have no idea where to start. I'm familiar enough with C++, but have no idea how to go about doing anything with a phone-line. I can plug a phone-line into my computer, but I have no idea how to get my program to be able to use that connection. There's WinSock2 for being able to use my ethernet connection, is there something similar I'd be able to use to use the phone line? As it's using the same ethernet jack, I wonder if it's even possible to use WinSock2 to use the phone-line?
I saw this post, which wasn't particularly helpful: stackoverflow link , which points out Dual-tone multi-frequency signaling. I stumbled across this site: link, but isn't really going to help me get started.
So I was wondering, is there some sort of library out there that would allow me to tap into a phone-line that's connected to my computer? Is there a standard somewhere out there concerning phone-lines and what the different combinations of tone's mean? Can anyone here help get me started? I realize it's somewhat of a big undertaking, so any push in the right direction would be greatly appreciated. Thanks.
[Update:]
I found this question, which is a step in the right direction, but I'm not sure yet if it helps me (I need to go to bed, and will take a look at it in the morning). I did see mention of a Microsoft Telephony API though, I'll try doing more research on that tomorrow.
If working with MS products is not an absolute necessity, you might also consider taking a shot at Asterisk. This is an open-source PBX (in software) that allows development on Linux, Windows (emulated) and Mac. At the company where I work, we use it for implementing small-scale exchanges, about a 100 lines or so. It also interfaces well with VoIP and allows a whole host of protocols. I have developed scripts and programs in C++ that work on voice packets in real-time, and so far, my experience has been good. As for your stated use-case of blocking telemarketers etc., this would be a very good fit. Check out further details here.
After doing more research, having one link lead to another link, and coming up with new search terms, I stumbled across this site that looks like it could kick me off using the Windows Telephony API in C++: link. This link includes open source c++ samples showing how to do the basics of what this question asks, I'll just have to test to see if they actually still work.
This is only the beginning of my research, so I'll keep you posted on any other findings. If anyone else is knowledgeable in this area, please still feel free to drop me information on what I want to accomplish.
A few colleagues and I created a simple packet capturing application based on libpcap, GTK+ and sqlite as a project for a Networks Engineering course at our university. While it (mostly) works, I am trying to improve my programming skills and would appreciate it if members of the community could look at what we've put together.
Is this a good place to ask for such a review? If not, what are good sites I can throw this question up on? The source code is hosted by Google Code (http://code.google.com/p/nbfm-sniffer) and an executable is available for download (Windows only, though it does compile on Linux and should compile on OS X Leopard as well provided one has gtk+ SDK installed).
Thanks, everyone!

UPDATE: Thanks for the great feedback, everyone. The code is completely open-source and modifiable (licensed under Apache License 2.0). I was hoping to get more holistic feedback, considering that my postings would still be very lengthy.
As sheepsimulator mentioned, GitHub is good. I would also recommend posting your project on SourceForge.net and/or FreshMeat.net. Both are active developer communities where people often peruse projects like yours. The best thing for your code would be if someone found it useful and decided to extend it. Then, you'd probably end up with plenty of bug fixes and constructive criticism.
You might get some mileage by posting the code out in the public space (through github or some other open-posting forum), putting a link here on SO, and seeing what happens.
You could also make it an open-source project, and see if people find it and use it.
Probably your best bet is to talk to your prof/classmates, find some professional programmers willing to devote their time, and have them review the code. Like American Idol-esque judging, but for your software...
As #Noah states, this is not the site for code review. You may present problems and what you did to overcome those problems, asking if a given solution would be the best.
I found a neat little website that might be what you are looking for: Cplusplus.com
I have read about Thrift while trying to find out how to use Google Protocol Buffers. I have been searching for some reference that shows how to go about using it with a simple working example for C++. It's been frustrating not being able to find any such site. It is a bit surprising that almost all the examples use Java, a language that has cross-platform RMI already at its disposal. May be I have missed something in searching, and I would very much appreciate if anyone can give a reference to a tutorial with a working example, however small.
TIA,
-Sviya
I've never used Thrift, but Googling for "thrift" brought me to this page - http://incubator.apache.org/thrift/ - which has a C++ example at the bottom of the page.
The thrift wiki has this page - http://wiki.apache.org/thrift/ThriftUsageC%2B%2B - which has more info on using it with C++
Also,
once when you install thrift in folder tutorial you have example of thrift file,
server&client implementations in different languages and README file.
This is good place to start!
Because there were no tutorial on the web, I created one in my blog.
You can check my full tutorial about Thrift in: My Blog
Since it's too long, I cannot post my answer here. But I think my blog is a good resource for anyone who wants to get started with Thrift.
So I understand that there are a few options available as far as parsing straight XML goes: NSXMLParser, TouchXML from TouchCode, etc. That's all fine, and seems to work fine for me.
The real problem here is that there are dozens of small variations in RSS feeds (and Atom feeds too), so supporting all possible permutations of feeds available out on the Internet gets very difficult to manage. I searched around for a library that would handle all of these low-level details for me, but came out without anything.
Since one could link to an external C/C++ library in Objective-C, I was wondering if there is a library out there that would be best suited for this task? Someone must have already created something like this, it's just difficult to find the "right" option from the thousands of results in Google.
Anyway, what's the best way to parse RSS/Atom feeds in an iPhone application?
I've just released an open source RSS/Atom Parser for iPhone and hopefully it might be of some use.
I'd love to hear your thoughts on it too!
"Best" is relative. The best performance you'll need to go the SAX route and implement the handlers. I don't know of anything out there open source available (start a google code project and release it for the rest of us to use!)
Whatever you do, it's probably a really bad idea to try and load the whole XML file into memory and act on it like a DOM. Chances are you'll get feeds that are much larger than you can handle on the device leading to frequent memory warnings and crashes.
I'm currently trying out the MWFeedParser #Michael Waterfall is developing.
Quite easy to set up and use (I'm a beginner iPhone developer).
His sample code for using MWFeedParser to populate a UITableViewController implementation is helpful as well.
take a look at apple's XML Performance sample -- which points to using libXML directly -- for performance and quicker updates to the display. Which may be important if you are working with very large feeds.
Check out my library for parsing Atom feeds, (BSAtomParser) at GitHub. It doesn't care about validating the feed, it does its best at returning whatever is valid. The parser covers most of RFC 4287, even extensions.
Here's my solution: a really simple yet powerful RSS parsing library: https://github.com/H2CO3/RSSKit
Have you looked at TouchCode yet? I don't think it has an RSS processor, but it might give you a start.
http://code.google.com/p/touchcode/
I came accross igasus project on sourceforge today. I haven't used it or really checked it, but perhaps it might help.
From their site:
igagus is a web service for the iPhone that allows aggregation of RSS to be delivered in an iPhone friendly format.
Actually, I was trying to suggest you ask on the TouchCode discussion board, because I remember someone was trying to expand it to support RSS. That might be a decent starting point. But I was being rushed by my wife.
But I see now that TouchCode doesn't have a discussion board. I'd still ask the author, though, he might know what came of that effort.
This might be a reasonable starting point for you. Atom support isn't there yet, but you could help out?
