Is there any free service to which I could send a UDP packet and it would respond telling me what is my "real" UDP port? (my application is behind a NAT)
This kind of service could allow me to make a p2p coordination server with normal php hosting.
The p2p clients would know their UDP ports from this service
They will then contact my server over HTTP (which is what regular web hosting allows) and tell it their port (and ip, which is normally supplied to cgi scripts)
My server will give the clients the IP addresses and ports of the other clients.
Hi ,
Please give me a realtime simple example for the below questions :
Where to use interface rather abstract class
Where to use abstract class rather interface
I need code snippet for both .
Which takes low memory and which performs well . Do I need to consider the design aspect also?
What is the conceptual difference not the syntactical difference .
Hi folks,
while my time developing on android I was looking for a functionality to get logcat messages from my real device (when starting an app on it from eclipse) and not only from my emulator...
Does someone know how to enable such a feature?

I've noticed that within Notes (8.5.2, basic client, fat client and iNotes) the date/time displayed on the eMail envelope AND the date/time on the message header is the same and appearently that time that Domino received the message.
When using BES, the message forwarded to the BlackBerry by Domino/BES has the RECEIVED date/time on the envelope and the SENT date/time displayed in the message.
In the basic/fat client with properties the sent time is viewable in one of the "Received" tags.
Having the sent time easily viewable is helpful, especially if your trying to trouble-shoot a problem.
Is this a configuration feature?
Is it selectable in the client or in Domino?
Thx
I've seen questions asked here before, but they do not address the issue. That said:
"In App Purchases" specifically may not be real world goods or services, according to Apple. What services allow integration with iPhone apps so that I can use ObjectiveC to sell things in an iPhone app?
Is it possible to have Outputs from PL/SQL in real time? I have a pretty huge package that runs for more than an hour and I'd like to see where the package is at a particular time.
Anyways, I currently do this with a log table, which gets filled up with hundreds of log descriptions per run, I'm just curious if this is possible.
Thanks!
I know how to write program in PHP and implementation of MVC model. but I really want to practice coding like the coding in real world??? I was wondering is there any specific example or book which can show me the tricks or logic and the way professional programmers consider about coding???
Hi there ,
i always asked myself. Why are there so many DB management systems?
I am not an DB expert and i never thought about using another DB than mysql.
Programming languages offer different paradigms, so there it makes sense to choose a specific language for your purpose.
What are factors to choose a specific DB management system ?
Hi,
i always like to real-time edit a web page source in the browser and updated as i type, but firebug really sucks, i can't insert scripts in the current page, some times the changes i type aren't updated at all, Is there any robust firefox/chrome extension for that?
i try to temporarely edit/add code to an existing web page in the internet, not a local one
Thanks
I'm having a little trouble understaing how I would use covariance and contravariance in the real world.
So far, the only example's I've seen have been the same old array example.
object[] objectArray = new string[] { "string 1", "string 2" };
It would be nice to see an example that would allow me to use it during my development if I could see it being used elsewhere.
Can anyone point me to some useful resources?
I have a asp.net vb.net app, with a upload file control, when i upload the file i can get the type of file the extension : .(some thing),
But if the user change the extension how i can get the real type of file?
Any ideas??
I'm looking for a C or C++ API that will give me real-time spectrum analysis of a waveform on Windows.
I'm not entirely sure how large a sample window it should need to determine frequency content, but the smaller the better. For example, if it can work with a 0.5 second long sample and determine frequency content to the Hz, that would be wicked-awesome.
Hi,
I have a strange problem. To detect outgoing calls I have registered a broadcast receiver for android.intent.action.PHONE_STATE. When the state becomes OFFHOOK, then a conversation is started. It seems working on emulator: the debugger in fact reaches some code while it doesn't work on real device (Acer Liquid). Is it possible?
Which is a way to detect outgoing calls?
Thanks
I want to take two times (in seconds since epoch) and show the difference between the two in formats like:
2 minutes
1 hour, 15 minutes
3 hours, 9 minutes
1 minute ago
1 hour, 2 minutes ago
How can I accomplish this??
Hi,
I want to learn C , UNIX and LINUX, and more about embedded systems. Very much interested in them. Are there any online courses or websites which can guide me. And please suggest books to read in learning them.
Thanks for your time.
I'm interest in learning how to use jquery comet to create real-time multi-user note taking like etherpad used to offer.
Can anyone offer any tips/tutorials/plug-ins... to point me in the right direction?
Thanks
Every thing is OK in simulator but when I deploy my app to real device (jailbroken) I can't find app's Application Preferences in Setting or my iPhone!
What wrong?! Please help me!
I find that most of my work involves creating shims so that different systems can communicate with each other.
Is there any software solutions that handle this. I don't want to make my own.
For example if we received a message like { a: 'abc', b: 1 } from System1, we might want to send { a: f('abc'), c: 'System1'} to System2.
Know of anything like that?
When you sign up to google analytics it instructs you to use a javascript snippet on every page you want to track. This code includes an API key, which is visible to everyone who views your source code.
How does it guarantees that the request is coming from the real site, and not from a third-party who wants to mess with your statistics? Does it check the HTTP Referer header? Even that is not safe, as it can be forged.
Are there any real stories about computer crime? I'm talking about stuff like in "Office Space", stealing fractions of pennies a couple of million times... Like that, only actual events. And not Captain Crunch, please, making phone calls for free does not count. No, actual robberies or super smart frauds that depended on computer technology to some extent. Links or books for further reading please.
Me and my friends play Age of Empires every weekend and create an Ad-hoc network each time before playing. But each time we all get the SAME IP Address even if a new ad-hoc network is created. Is this something to do with the Game's algorithm or does the laptop remember our previous IP Address.
EDIT:
What is the algorithm that is used to distribute the IP Addresses? If the algorithm uses random function how come same IP addresses are being allocated.
I need Backup configuration of Hudson Master systems
Detailed information
If a Hudson Master system goes down, we need to be able to bring it back up on a different VM as soon as possible (may be 3 hours). Therefore, I need to develop a way to backup the configuration and resetup a new VM reliabily. can any body let me know best way step by step.
THANKS
