channels

问题 I am trying to play around with goroutines and channel package main import ( "fmt" "math/rand" "time" ) func boring(msg string) <-chan string { c := make(chan string) go func() { for i := 0; ; i++ { c <- fmt.Sprintf("%s %d", msg, i) time.Sleep(time.Duration(rand.Intn(1e3)) * time.Millisecond) } }() return c } func main() { c := fanInNew(boring("joe"), boring("anh")) for i := 0; i < 10; i++ { fmt.Println(<-c) } fmt.Println("You both are boring, I am leaving") } func fanInNew(input1, input2 <

问题 I am a new in this field, maybe what I ask it's impossible to implement. What I try to do is - recording an audio with n-channels to WAV file with n-channels. I use arecord utility: arecord --format=S16_LE --channels=8 --rate=16000 --file-type=wav myfile.wav In my input I see different channels: But in output of recording I see all channels are mixed: Is it possible to record WAV file without mixing channels? Is it possible to record each channel to separate channel? 来源： https://stackoverflow

问题 So I just launched a website with Channels 2.0 Daphne 2.2.0 and asgi via Heroku (Hobby) and Postgres (trial). When I launch my website, I click around for a few pages and I get a 500 error. The error message I get emailed is FATAL: too many connections for role ..." When I run heroku pg:killall or wait long enough I can click around a few more times until the error message repeats itself. However, when I run heroku pg it shows Connections 0/20 . Does anyone know what is going on and how I can

问题 I thought I can find anything on this great site but now I seem to face the issue with no answer :) Please help! Thing is, I need to play up to 6 different wav files with 1 channel each into 6 channels supported by system mixer (left, right, surround left, etc). Using 6 different SourceDataLines looks logical but from what I see, Mixer cannot do per-sample synchronisation for them, so I came up with interleaving them in separate thread and use only one SourceDataLine to play it. It works fine

问题 I am new to Golang. Right now I am trying to figure out how to make an any-to-one channel in Golang, where the setup is as follows: say I have two goroutines numgen1 and numgen2 executing concurrently and writing numbers to channels num1 resp. num2. I would like to add the numbers sent from numgen1 and numgen2 in a new process, addnum. I have tried something like this: func addnum(num1, num2, sum chan int) { done := make(chan bool) go func() { n1 := <- num1 done <- true }() n2 := <- num2 <-

问题 I am trying to run the multichat project from django channels-examples on a server. It works locally on a windows machine but when I put this on the linux server and start it with runserver it does not: ./manage.py runserver Then when I call up the website, it is shown correctly but as soon as the JS sends it websocket request I always get this reponse: [2016/08/02 14:35:48] HTTP GET /chat/stream/ 404 [0.04, 127.0.0.1:40186] ....(many lines of this) So the websocket request is handled as an
