ruby - Net::FTP and open-uri hanging while trying to put binary file to from URL to FTP server -


I have a scenario where I have an S3 URL that contains binary content that needs to be transferred to an FTP server is. I am using net :: FTP , open-yurry and Ruby 2.0.0-p353. 

  requires net / ftp 'Required' Open-Yuri 'net :: FTP.open (x, y, z) do | Ftp | Ftp.putbinaryfile (open (an_s3_url), 'remote_filename', 4096)   
 The code above is a temporary  open-uriXXYY - *  temp file is created Dyer, but then hanged. I have no idea why. Interrupting the function causes the following trace to occur:  
  home / ubuntu / .rvm / rubies / ruby-2.0.0-p353 / lib / ruby ​​/ 2.0.0 / net / Ftp.rb: 434: 'Accept' in: /home/ubuntu/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/2.0.0/net/ftp.rb:434:In / home / 'Transfer' Ubuntu /. R.V.M. / Ruby / Ruby 2.0.0-P353 / Lib / Ruby / 2.0.0 / Net / FTP RB: 543: in Stobarini / Home / Buntu /. Rubies / ruby-2.0.0-p353 / lib / ruby ​​/ 2.0.0 / net / ftp.rb: 199: /home/ubuntu/.rvm/rubies/ruby-by_bb/ From 2.0.0-p353 / lib in `with_binary '/ruby/2.0.0/net/ftp.rbitter42:en/home/ubuntu/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/2.0. 0 'block in the strawberry' from monitor. RB: 211: /home/ubuntu/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/2.0.0/net/ftp.rbitter41:IN From 'Stobbinari' / home to `mon_synchronize '/ ubuntu /.rvm/rubies/ruby-2.0.0-p353/lib/ruby/2.0.0/net/ftp.rb:690:in `putbinaryfile '  
 The action is to file To get it again and then put it, but it seems friction. Is there any reason why I can not do it like this, or am I making something clear? Without problems or without similar problems The answer was to use Passive FTP - it was obvious (?!) I was missing.  
 It is set to false by default.  
  net :: FTP.open (x, y, z) {| ftp | Ftp.passive = true ...}   
 worked like a charm.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

Calling a C++ function from C# by passing a string with variable size to it -

I am calling a string with a C + code and calling from the C # code. The C ++ function is responsible for filling the string material. The following code is: C #party: var abc = new string builder (4096); // will have to change this var result = Basic methods. SignCrcFile (ABC); C ++: bool __cdecl SignCrcFile (char * abc) {... char * tempStr = "hello all"; // for example // copy it to ABC string strcpy (ABC, tempStr); Back true; } The problem is that tempStr's size in the C ++ function is dynamic (the above assignment for TempStr is only an example). In such a case, it is not a hard code that the size of ABC string is in the size of 4096 bytes on the C #. The first solution can be a solution to create 2 functions on the C ++ side to get the size of the string. Then allocate that size using StringBuilder in the C # side then use the next function to bring the entire string from C ++ to the C #. But no suggestion this may not be the most optimal way? ...
