permissions

问题 I've got a permissions/group based setup that I'm trying to merge results on.

问题 Using WiX, I'd like to install a file with permissions to read but not write (I don't even know if Windows will allow such blasphemy). Here's what I've tried: I import the UtilExtension dll with no problems, so I have no trouble accessing the <Permission/> and <PermissionEx/> elements (I don't know if the dll is needed for just the < Permission /> element, so I add it anyways). From there, I've tried every variation using both of these elements that I can think of. Here's a nice simple one

问题 I'm with a web application that let anonymous users to upload images, transform them and get them later. I have a directory with www-data group owner and 1770 permissions, where the images are uploaded. In Apache configuration, AllowOverride set to none and Options to -Indexes .

问题 Since Runtime Permissions were introduced in Android Marshmallow, I've been meaning to apply the new way for requesting permissions and I've read and understood the dangerous permissions and how to check for them and request them.
