• Is it possible to detect Android and iOS devices based on DHCP requests?

  - by abbot

  I want to configure DHCP server in a way that it puts "regular" smartphones and tablets into a separate subnet. Is it possible to detect if the DHCP request comes from an Android or iOS device based on the DHCP request itself? For example: a Sony android phone which was around set the following DHCP options in request, which are potentially useful for identification bootp.option.vendor_class_id == "dhcpcd-5.2.10:Linux-2.6.32.9-perf:armv7l:mogami" bootp.option.hostname == "android-c7d342d011ea6419" Are there any known common patterns in DHCP request options better then MAC prefix?

• oddities in interference of linux extened ACLs and 'regular' permissions

  - by abbot

  I've got some legacy code which checks that some file is read-only and readable only by it's owner, i.e. permissions set to 0400. I also need to give read-only access to this file to some other user on the system. I'm trying to set extended ACLs, but this changes 'regular' permission bits in a strange way also: $ ls -l hostkey.pem -r-------- 1 root root 0 Jun 7 23:34 hostkey.pem $ setfacl -m user:apache:r hostkey.pem $ getfacl hostkey.pem # file: hostkey.pem # owner: root # group: root user::r-- user:apache:r-- group::--- mask::r-- other::--- $ ls -l hostkey.pem -r--r-----+ 1 root root 0 Jun 7 23:34 hostkey.pem And after this the legacy code starts complaining that the file is group-readable (while it is actually not!) Is it possible to set the extended ACLs in such a way that some other user will also have read-only access, while the file will appear to have only 0400 'regular' permissions?

• How to add a constructor to a subclassed numeric type?

  - by abbot

  I want to subclass a numeric type (say, int) in python and give it a shiny complex constructor. Something like this: class NamedInteger(int): def __init__(self, value): super(NamedInteger, self).__init__(value) self.name = 'pony' def __str__(self): return self.name x = NamedInteger(5) print x + 3 print str(x) This works fine under Python 2.4, but Python 2.6 gives a deprecation warning. What is the best way to subclass a numeric type and to redefine constructors for builtin types in newer Python versions?

• Sorting an array in PHP based on different values

  - by Jimbo

  I have an array whose elements are name, reversed_name, first_initial and second_initial. A typical row is "Aaron Smith", "Smith, Aaron", "a", "s". Each row in the array has a first_initial or second_initial value of "a". I need to display the rows alphabetically but based on the "a" part, so that either the name or reversed_name will be displayed. An example output would be: Aaron Smith Abbot, Paul Adrian Jones Anita Thompson Atherton, Susan I really have no idea how to sort the array this way so any help will be much appreciated!
