c++ - Easiest way to get textualized binary (0s and 1s) for a simple C/CPP program on OSX -

-

First of all, I know this is a very strange request. I want it as a teaching aid in a computer classroom. It's good to be able to display an instruction in its binary form, which are going to bits in opcode, logic, etc. Full hex is fine, but I am looking for binary if possible.

I am using OSX (Mountain Lion).

I used the following commands (different) to get the assembly: 

  clang -emit-llvm -s sum CAP clang -S-mllvm - I used the following command to get some hex values:  
  otowal sum. O -tV  
 
 But I would really like to get a complete line of binary copy instruction in some way. Some would be ideal to be underlying, but maybe it's asking too much. 
 
 I think I could only see the obj code in a hex editor, but did not believe that they would be correctly aligned properly to read or understand "easy".

I can talk only for Linux, but perhaps it still helps. For example (sum.cpp): 

  #include  
 For example, to get an interspersed source-hex-asm-output,  Objdump . ; Iostream & gt; using namespace std; Int zodiac (int a, int b) {return a + b; } Int main () {int a = 3, b = 4, c; C = Yoga (A, B); Cout & lt; & Lt; C & lt; & Lt; Endl; Return 0; }

Compilation & amp; Objdump: 

  clang ++ -g sum.cpp objdump -d -S -C -Mintel a.out & gt; Objdump.txt

You can find inside the objdump.txt and get: 

  00000000004007f0 & lt; Sum (int, int)>: #include & lt; Iostream & gt; using namespace std; Int Sum (int a, int b) {4007f0: 89 7c 24 Fc mov DWODTttR [RSP-0x4], ADI4007F 4: 89 74 24FOM Dvord PTR [RSP-0x8], ASI Return A + B; 4007f8: 8b 74 24 Fc mov ESI, DWORD PTR [RSP 0x4] 4007fc: 03 74 24 To add F8 ESI, DWORD PTR [RSP 0x8] 400800: 89 f0 mov eax, ESI 400802: C3 Retired 400,803: 66 66 66 66 2e 0f 1f data32 data32 data32 nop word ptr cs: [Rax + Rax * 1 + 0x0] 40080a: 84 00 00 00 00 0000000000400810 & lt; Main & gt:: Integer main () {400,810: 55 push RBP 400,811: 48 89 E5 Mov RBP, RSP 400814: 48 83 EC 20 Dy.

The last step will be to develop a program that converts hex into binary.

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. ...
