问题 I want to run my Android service(real-time notification service) after application installed and force it to work even application closed. This service responsible for listening my real-time notification server, when notification received I create Android notification and maybe run my app, if it is closed. I assume that my way is not correct for this case and there is another way working with real-time notification. I will be grateful if you give some link or a small explanation. 回答1: the

问题 First of all, is it a nice and successfull idea to use peer 2 peer to broadcast realtime video ? I know that it will make the application scallable and will allow more users to get the real time video without affecting the server much, but are there drawbacks performance-wise and video quality-wise ? Now the specefic question, my intention is to share realtime video, and then use peer2peer in the webclient level using websockets, are there any libraries that are used for this purpose? I know

问题 This is a conceptual question regarding the realtime editing of large files. Imagine we have a 50 Mb txt file in Google Drive that we want to allow users to edit. We require that the user downloads the entire file before they start editing (The user will have to wait for a while, but this is ok). The user then changes a single word in the 50 Mb text file. How can we possibly update the file in Google Drive without uploading all 50 Mb of text. 回答1: If you are creating an Android application,

问题 I'm trying to create a program, using Qt (c++), which can record audio from my microphone using QAudioinput and QIODevice. Now, I want to visualize my signal Any help would be appreciated. Thanks [Edit1] - copied from your comment (by Spektre) I Have only one Buffer for both channel I use Qt , the value of channel are interlaced on buffer this is how I separate values for ( int i = 0, j = 0; i < countSamples ; ++j) { YVectorRight[j]=Samples[i++]; YVectorLeft[j] =Samples[i++]; } after I plot

问题 I have need to create an oscilloscope simulator using the ms-chart control. I store my data in an array. But I don't know how to create the "moving effect" - continuous update of the control. (adding / removing points from the chart control) and having a vertical line drawn every second on the control. My code is: private void Form1_Load(object sender, EventArgs e) { chart1.Series["Series1"].ChartType = SeriesChartType.Line; chart1.Series["Series1"].BorderWidth = 3; // NO grids chart1

问题 I am working on designing a new platform for a certain type of application. These applications will mainly exists on both iOS and Android devices. One of the main requirements in these applications is that is syncs real time data and is secure. My thought went directly to using some kind of queuing protocol using sockets. The restrictions on the server is that it would have to be written in either Java or PHP. However, the clients are unrestricted. Like I mentioned, mainly iOS (Objective-C)

问题 Im new to matlab coding so im still trying to get my head around things. Pretty much im working with interia sensors which output the sensors orientation data every 10ms. Im able to store this data into a text file which is continuously updating. My task now is to plot this data in real time. This involves continuously accessing and reading from the text file (every 10ms if possible) and graph this data with respect to time. Can any of you guys give me some guidance onto what would be the
