问题 I try to make random loss from a given bit stream. Assume that I have a bit stream as 10 01 10 11 00 Now I will create a code to implement random loss. The function with two inputs are original bit stream and percent loss. Output function is output bit stream int* bitloss(int* orbit,int size_orbit,float loss_percent) { srand(time(NULL)); int* out_bitstream=(int*)malloc(sizeof(int)*size_orbit); double randval ; for(int i=0;i<size_orbit,i++) { randval = (double)rand()/(double)RAND_MAX; if

问题 I am working with Hough Circle Transform with my RaspberryPi and when I take a ROI to check for circle like this: for (x,y,w,h) in trafficLights: cv2.rectangle(image,(x,y),(x+w,y+h),(0,0,255),2) roi = image[y:y+h,x:x+w] roi = cv2.medianBlur(roi,5) circles = cv2.HoughCircles(roi,cv2.HOUGH_GRADIENT,1,20, param1=50,param2=60,minRadius=0,maxRadius=0) circles = numpy.uint16(numpy.around(circles)) for i in circles[0,:]: if i[2] < 100: cv2.circle(image,(i[0],i[1]),i[2],(0,255,0),2) cv2.circle(image,

问题 I've been struggling with the crap documentation of Google and can't get the program to join the channel even though it connects to the server fine. (It says Connected to server) //On Form Make procedure TForm2.FormCreate(Sender: TObject); begin IdIRC1.Connect(); end; //on connected procedure TForm2.IdIRC1Connected(Sender: TObject); begin ShowMessage('Connected to server'); IdIRC1.Join('#TheChannel', 'password'); end; Once i close the form an error comes up saying: Project raised exception

问题 so I have the following test Go code which is designed to read from a binary file through stdin, and send the data read to a channel, (where it would then be processed further). In the version I've given here, it only reads the first two values from stdin, although that's fine as far as showing the problem is concerned. package main import ( "fmt" "io" "os" ) func input(dc chan []byte) { data := make([]byte, 2) var err error var n int for err != io.EOF { n, err = os.Stdin.Read(data) if n > 0

问题 Is it necessary to register interest to write to a NIO client socket channel to send data? Do I have to always call socketChannel.register(selector, SelectionKey.OP_WRITE) , or some equivalent, before writing to the client SocketChannel to be able to write there? Would not be enough simply to write data to client SocketChannel with channel.write(outputBuffer) and awake potentially blocked Selector , all in a client thread? The main selector loop would then look like this: Selector selector =

问题 If i know author or Channel ID then link is worked but i need get my channel ID. https://gdata.youtube.com/feeds/api/videos?author=[Channel ID]&orderby=viewCount But i don't have a channel ID. I want using my Google account (My username and password) and get my channel ID using v2 Google Gdata Youtube API, not v3 Thanks for help. Astin Runa 回答1: You can try with the channels endpoint passing the part as id, forUsername and key https://www.googleapis.com/youtube/v3/channels?part=id&forUsername

问题 My input is a csv file as given below: USER_ID, USER_NAME, FREQUENCY, FREQUENCY_DETAIL A123, AAA, ANNUALLY, 1-JUN B123, BBB, INVALID_FREQUENCY, 21-JUN C123, CCC, ANNUALLY, APR D123, DDD, WEEKLY, 1-DEC Validations: USER_ID -> alphanumeric USERNAME -> alphabets only FREQUENCY -> must be one of DAILY, WEEKLY, MONTHLY , ANNUALLY FREQUENCY DETAIL -> Pattern \\d{1,2}-\\w{3} My Bean is as follows: class UserBean { String userID; String userName; String frequency; String frequencyDetail; String

问题 I'm trying to build a simple pipeline-like functionality that executes each stage of the pipeline is separate threads and glues them all together with channel passing. Pipe::source(buffer) .pipe(|input, output| {...}) .pipe(|input, output| {...}) .sink(writer) I cannot for the life of me figure out the function signature for the pipe() function. Here's my code: use std::sync::mpsc::channel; use std::io::{ChanReader,ChanWriter}; use std::thread::Thread; struct Pipe { incoming: ChanReader }

问题 I am writing a go project which is a simple web crawler to crawl links on the website. I want to experiment the concurrent features such as goroutines and channels. But when I run it it didn't go through. Nothing is showed as if there is nothing happening. I have no idea what went wrong. Can somebody point it out for me? It works and shows all the crawled links if I remove the channels logic but I want it to send the links into a buffered channel and then display the links before ending the
