uid

I'm working on an IMAP client using Ruby and Rails. I can successfully import messages, mailboxes, and more... However, after the initial import, how can I detect any changes that have occurred since my last sync? Currently I am storing the UIDs and UID validity values in the database, comparing them, and searching appropriately. This works, but it doesn't detect deleted messages or changes to message flags, etc. Do I have to pull all messages every time to detect these changes? How do other IMAP clients do it so quickly (i.e. Apple Mail and Postbox). My script is already taking 10+ seconds

I am trying to create dynamic tabs in WPF, and I'm trying to write a content template that will only apply to some tab items. I want to be able to create an identifier for the content template so that I can reference it in the code behind, and so that I can selectively apply it to only some tabs in a single TabControl. However, I am confused about these three different xaml identifiers. What is the difference, and which one is best for my purposes? The 'x:' specifies the namespace, which would in your case most likely be " http://schemas.microsoft.com/winfx/2006/xaml " You will see the alias

I would like to be able to get the Linux UID (user ID) of an installed Android application. Excerpt from Security and Permissions : "At install time, Android gives each package a distinct Linux user ID. The identity remains constant for the duration of the package's life on that device."

I am trying to create deb package from LXC rootfs, and after creating it I want to install that package any computer. Up to this point I achieved packaging and installing deb package, however after installation of LXC package, I cannot be superuser in that lxc. I get this error when I use "sudo" command. sudo: effective uid is not 0, is sudo installed setuid root? thanks in advance. I just had this same exact problem on Mac OS after strangely deciding to screw my own system by doing: sudo chmod -R /usr/bin . If that's someone else's case just open Disk Utility , select your OS disk ("Macintosh

The documentation for os.getuid() says: Return the current process’s user id. And of os.geteuid() says: Return the current process’s effective user id. So what is the difference between user id and effective user id ? For me both works same (on both 2.x and 3.x) . I am using it to check if script is being run as root. Blckknght To understand how os.getuid and os.geteuid differ, you need to understand that they're are not Python specific functions (other than the os module prefix). Those functions are wrapping the getuid and geteuid system calls that are provided by essentially all Unix-like
