real-time

问题 I am using a real-time-data from a proprietary application which provides real time weather data. All I know know from the data is, it provides a link to import to excel as: =RTD("4cast.wetter",,"city","parameter") This parameter includes Temperature, Humidity, Wind speed, Rain fall etc. I tried reading the support link provided at excel documentation but couldn't get if it could be used with Python. http://support.microsoft.com/kb/289150 So now my real purpose is to use this Data received by

问题 This does not look trivial, specially for a read/write buffered FileChannel. Is there anything opensource implemented somewhere that I can base my implementation on? To be clear for those who did not understand: FileChannel does buffereing in the OS level and I want to do buffering in the Java level. Read here to understand: FileChannel#force and buffering @Peter I want to write a huge file to disk from a fast message stream. Buffering and batching are the way to go. So I want to batch in

问题 i'm creating a realtime multiplayer game in unity. i'm using this plugin : https://github.com/playgameservices/play-games-plugin-for-unity i need to move a ball in field(ground). i can send and receive message between two player. but i don't know which information should i send and when to send. for example i'm sending myObject.transform.position; can you give me some ideas about syncing the ball's move in field? 回答1: You can try sending the target position instead. Then when you receive this

问题 currently i m working on the Tizen IDE. I had read the input data from the microPhone and apply the FFT on it... but everytime i gets the nan output. here is my code.. ShortBuffer *pBuffer1 = pData->AsShortBufferN(); fft = new KissFFT(BUFFER_SIZE); std::vector<short> input(pBuffer1->GetPointer(), pBuffer1->GetPointer() + BUFFER_SIZE); // this contains audio data std::vector<float> specturm(BUFFER_SIZE); fft->spectrum(input, specturm); applying FFT.. void KissFFT::spectrum(KissFFTO* fft, std:

问题 I've been trying to plot serial data from an arduino in real-time using matplotlib's animation function. The data comes from a ntc temperature sensor. The plot I was able to get displays a sigle line all the time, and the line is only translated up or down as the teperature changes. I'd like to know what can I do to view the curves representing the changes in the plot. Here´s the code: import serial from matplotlib import pyplot as plt from matplotlib import animation import numpy as np

问题 I am currently trying to make a browser plugin using crossrider that will sync bookmarks but as there is no "on new bookmark" event how do I sync all upload new bookmarks to the server and update bookmarks lists on other connected machines in realtime? I would be inclined to do this with a websocket but as I said it is not event based. So do I poll all the clients every n seconds? That seems like a lot of data being moved and it seems taxing on the server as the process presumably wold

问题 I was recently reading this article from the Figma engineering blog: https://www.figma.com/blog/rust-in-production-at-figma/ and was curious about their NGINX setup for multiplayer routing. This is how it looks: Where they have M number of servers, and where each server has W number of workers. Figma lets users collaborate on design documents in real-time, and each document (i.e. the logic that takes care of the real-time multiplayer processing for each doc) always lives in one specific

问题 I'm using windows server 2012 and activated websockets on it. When signalr use websockets, the connection is successfully started but no event in client side are called, only if I force signalr to connect with long polling.... Any suggestion ? Thanks 来源： https://stackoverflow.com/questions/30870898/signalr-websocket-successfully-connected-but-client-events-only-called-with-lo

问题 There was a similar topic How to export Simulink data to the MATLAB Workspace during simulation?. pm82 answered that this is possible using set and get commands. But I didn't understand how to use timer callbacks to read the data! Can anyone pls explain it to me? However, in the above question they discussed how to write Simulink data into the MATLAB Workspace. I want Simulink to write data into Excel during the simulation so that that data can be read by another application in real-time. Is

问题 Is there a specific metric which a system should meet to be considered/classified as real-time web application or a near- real time web application? When I see a non-functional requirement for a system on which I am working which states the solution shall return data in real time/near real time. I understand the definition of the terms (as found http://en.wikipedia.org/wiki/Near_real-time), but I was wondering if there were standards like one might find for an application UI (example: Gnome
