WebHDFS provides hooks for "rename", "delete" and other basic file manipulations. but here is no API hook for copy. Would someone mind explaining it or any good workarounds?
Thanks!
Using webhdfs you can :
a. Open and read a file.
b. Create and write to file
Using operation a and b you can emulate copy?
If there is a more efficient way I would like to know too:-)

I want to sign the user application with the user name if he makes a donation. For that I need to write the user name into the exe file. But the file cannot change itself because it is in use at that time. Do you know if anything can be done ? Of course, I can store the signature in a separate file or in registry, but in this way the signature can be lost. I want the modification to be permanent and cannot be changed by the user. I will accept any idea that help me accomplish this...
You can let the application make a copy of itself, then modify the copy, and then start the copy (with ShellExecute).
The modification could be inspired by the UpdateResource examples here: How to attach a resource file to an existing executable file?
The "signature" would be stored in a resource, so your application would have to read it from the resource, for example with Delphi's TResourceStream class.
I am using Rails (4.1.5) and I have generated a full documentation which has been put in /doc as by default. My app is publish online but internally. I would like to expose this documentation through an URL part of my actual (e.g. http://myapp.com/doc). I want to find a way to automate this as the "generate the doc" action will be done on my side to refresh the documentation.
Somebody have any idea what should be the trick for this? Route (if so, how), should I create a controller for that specifically?
Thank you in advance for any help on this.
I've done this using Dropbox. I run my documentation generator command and have it output to a location in my Dropbox folder. Then, my colleagues can simply open the index.html file at the shared location to view the documentation. But, in your case I suppose you could have your myapp.com/doc url redirect to the dropbox location? The advantage of all this being that you don't have to redeploy to have updated documentation -- just regenerate the docs since Dropbox does the uploading and hosting for you.
I'm searching a lot, but don't find any documentations or examples.
How to replace file from one directory to another on ftp server?
Any examples?
There is no "move" command in the ftp protocol.
Check this one:

I'd recommend to use this library https://github.com/karelia/ConnectionKit to work with FTP on iOS. There are lot of examples in README file.
I'm wondering how I can create a .zip file with images in it. Is there any way to do this?
You can do that by calling addAttachmentData:mimeType:fileName: on the MFMailComposeViewController - if you already have the zip file.
If your question includes creating the zip file, unfortunately that is not possible with a few method calls in iOS. You would need to use a third-party library for this, e. g. objective-zip.
yes, it is possible go here to find out:

look for the add atachment method.
Windows Live Messenger creates a number of files like
C:\Users\USERNAME\AppData\Local\Microsoft\Windows Live Contacts{ae86acef-5a45-4447-bc32-521fc9289e1a}\DBStore\contacts.edb
and stores contacts within. When looking on such files, it is obviouos that they have strict structure. However, I failed to find the description of contacts.edb structure in internet.
Does anybody knows this structure? Or maybe there are some parser sources available? (I do not need a exe for that, I know about NirSoft one).
There is a project called libesedb which might be of use here.
The contacts.edb file is an ESEBD file.
