synchronize

问题 I would like to synchronize two folders with each other. It should go two ways, always keeping the folders up to date (I use a regular cronjob). However, first I do not get the two way file transfer to work (it just downloads from the ftp and not the opposite). Secondly, it downloads the whole content from the ftp, even though the login information has been set up on the ftp so that access is only restricted to a specific folder. Why?? Here is the code (thanks in advance!): #!/bin/bash #get

问题 I built a modular program consisting of several programs (exe), and in some cases these modules are also in DLL. There are about 6 modules. All of these modules used functions of a Thread. This thread does not use visual components, what it does is basically analyze huge files (> 1GB). To improve the efficiency and organization, extract all the code relating to this file analysis, which is used by each of the modules. This facilitates updating and find error. The threads worked normally

问题 I am making an app that fetches JSON content of a blog. The titles of the blog articles are shown in tableView. The titles fetched were HTML encoded. So I decoded them using this code func configureCell(cell: UITableViewCell, atIndexPath indexPath: NSIndexPath) { let object = self.fetchedResultsController.objectAtIndexPath(indexPath) as NSManagedObject var encodedString = object.valueForKey("title")!.description var encodedData = (encodedString as NSString).dataUsingEncoding

问题 I recently had to correct security issues in a web-application (that I didn't create). The security problem was, it was using non-http-only cookies. So I had to set the session-cookie http-only, which means you can't read (and set) the cookie's value anymore from javascript. So far so seamingly easy. The deeper problem was, the web-application used JSON.parse(readCookie(cookieName)).some_value on a million places . So in order to not have to re-write "a million lines of code", I had to create

问题 I am facing an interesting problem and I wanted to see if anyone else tackled this situation before I spend days theorizing. I have 2 systems. The first system maintains a sorted list of data. Lets say it has a list of named activities. The user of this system can manually order them at any time. System 2 instantiates this list into itself when a new project is created. It also synchronizes with the original list. The user in system 2 can create custom activities. These do not synchronize

问题 I'm using ansible in the following way: ansible-playbook -f 1 my-play-book.yaml --ask-pass --ask-sudo-pass After this I'm asked to enter the ssh & sudo passwords (same password for both). Inside my playbook file I'm using synchronize task: synchronize: mode=push src=rel/path/myfolder/ dest=/abs/path/myfolder/ For each host, I'm prompted to enter the ssh password of the remote host (the same that I entered in the beginning of the playbook run) How can I avoid entering the password when
