prng - Is it possible to reverse a pseudo random number generator? -

-

Is it possible to change the pseudo random number generator? For example, take an array of generated numbers and get the original seed. If so, how will it be implemented?

Normally, no. For most generators it should be possible , if you have a whole series of numbers if you do not have all the numbers or do not know which number you have (you are 12th or 300th ?), You can not understand it at all, because you do not know where to stop.

You have to know the details of the generator. Linear congruential generator decoding is going to be different from doing so for a counter-based PRng, which is going to be different from Mersenne Twister, which is going to be different from a Fibonacci generator. Besides you also need to know the generator's parameters If you have all this and the equation is incomparable to generate a number, then it is possible. How, it really depends on PRNG.

apache - 504 Gateway Time-out The server didn't respond in time. How to fix it? -

Using a form submission on an embedded iframe , the customer downloads a compressed log file Requested. The request was sent to the server, which is the compressed log files, perform some database operations and returns a compressed file. After just 2 minutes, 504 gateway time-out server did not respond timely message on browser net panel How to fix this error? The log files were taking a long time to compress, and timeout was set to 2min The error was fixed by extending the file file: # # timeout: The number of seconds before getting the time out. # # # Timeout 120 timeout 600

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. ...
