问题 is there a way to create a P2P web-chat without any server ? 回答1: If you're willing to use Flash, check out Adobe Stratus, which allows for peer to peer data and video streaming. http://labs.adobe.com/technologies/stratus/ 回答2: Yes, but you must decide on a place to meet. If your friend send his ip over to you, you can connect. Then you only need to tell some more people to join. After some time you will get bigger and bigger. Then, if some link on the net fail, the cloud will be broken up in

问题 I need help understanding what the advantage of using an asynch framework is. Suppose I want to develop a simple chat web app. Why cant I write python code in the Django framework that does long polling where I dont send a response back the server until someone enters a new msg. What does Twisted provide that gives it an advantage for real-time apps like the chat app? Sorry I am obviously little confused about the need for an asynchronous framework. 回答1: Asynchronous servers support much

Does anybody know which,currently,is the best library for realizing a real time face-tracking solution for iPhone? I've done a research but I've found quite old articles about OpenCV portings. I would like to know if there is any specific,reliable,fast (and possibly free) AR solution for overlay in real time an

问题 I would like to add and plot the spectrum of signal on Qwt Oscillocope's example. My Idea is to create another seriesData class. SerieData. I wonder if there will not conflict between sample of SeriesData and sample of Signaldata or I just need to modify the signaldata? Any help and Advice would be appreciated. Thanks 回答1: input signal is usually in form of cyclic buffer the output buffer can be static one. This applies also for time domain plots. Without actually see your structures is

问题 I'm looking to develop a chat application with Pubnub where I want to make sure all the chat messages that are send is been stored in the database and also want to send messages in chat. I found out that I can use the Parse with pubnub to provide storage options, But I'm not sure how to setup those two in a way where the messages and images send in the chat are been stored in the database. Anyone have done this before with pubnub and parse? Are there any other easy options available to use

问题 I'm working on a project where I'll have one application in C# and another one in Python. The C# application will continuously analyse stream of data and raise a flag each time something interesting is detected. So each time there will be an event, my Python application will have to read it and continues with it own process, while other flags will continue being sent. As you understand the C# app won't wait for the Python one to finish its computation before sending another flag. So I was

问题 Does anybody know how to fix this warning message? 07-14 10:38:55.411 V/tracker-audiotest(22426): Recording Thread::run(): start audioRecord recording. 07-14 10:45:51.490 "W/AudioTrack( 607): AUDIO_OUTPUT_FLAG_FAST denied by client due to mismatching sample rate (44100 vs 48000)" When I test the audio latency on Android 4.4, I face a suddenly delay increasing after I saw this warning message. But I don't change the sample rate during the test and the initial setting is in 48kHz. This warning

问题 I am trying to create a real time graph using nvd3.js which would be updated periodically and with the impression that the data is processed in real time. For now I have been able to create a function which would update the graph periodically but I cannot manage to have a smooth transition between "states" like the line doing a transition to the left. Here is what I did using nvd3.js , here the interesting code is: d3.select('#chart svg') .datum(data) .transition().duration(duration) .call

I am in the process of choosing a networking library to implement a client/server system that cannot spare any microsecond. It will implement its own protocol to send and receive messages. I am looking for a good NIO framework that will allow me to easily develop the server and the client, without having to
