Why can't I print from background threads in Clojure Cider REPL in emacs? -

-

If I try to evaluate the following code in my emacs cider-repl, it is expected, but someone Not even in print per buffer or console How do I print it? 

  (dotstart [i5] (.start (thread. (FN [] (thread / sleep (rand 500)) (println (format "= & gt;% s" / CurrentThread)))))));% d; Zero

This works fine, however: 

  (println (format "% s is at% s" (thread / current thread)) ; = & Gt; 1 end on thread [nREPL worker-18.5, main] ----------- Mini buffer ---------------- - Void

println on a dynamic bound called Is to use * out * as Emacs dynamically copied buffer code as your output stream A rip binds to go to * out * , but if you make a thread, that code becomes the * out * root binding * Out * , which will not be buff in case of cider.

If you started repl using in cider-jack , when you Look at yourself the buffer list there should be a buffer with a name like * nrepl-server * which is the root output of * * binding. After running your code here's my content: 

  NREP server host 127.0.0.1 started at port 52034 - nrepl: //127.0.0.1: 52034 thread ended 1 thread [thread- 9, 5, main] 2 threads ending at 0 [thread-8,5, main] on the thread thread [Thread-10,5, main] 3 thread [thread-11,5, main] on the finished thread ] 4 threads ending at thread [thread-12,5, main]

in cider-jack , then output terminal where nrepl To start the process Will print.

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
