Lacking Credibility

This deletes all unknown files in an svn working copy.

#!/usr/bin/env pythonfrom ctypes import *import ctypes.utillibc = cdll.LoadLibrary(ctypes.util.find_library('libc'))def getCPUnums():    counts = {'logicalcpu': c_int(0),              'ncpu': c_int(0),              'physicalcpu': c_int(0)}    for k, v in counts.iteritems():        size = c_int(sizeof(v))        libc.sysctlbyname('hw.%s' % (k,),                          c_voidp(addressof(v)),                          addressof(size),                          None, 0)    return (int(counts['ncpu'].value),            int(counts['physicalcpu'].value),            int(counts['logicalcpu'].value))if __name__ == “__main__”:    print “”"CPU Counts:N:\t\t%dPhysical:\t%dLogical:\t%d”"” % getCPUnums()

Of course my Intel Core 2 Duo gives me the following.

sabrina dreid:~> python cpun.pyCPU Counts:N:              2Physical:       2Logical:        2

You could have just as easily done sysctl hw.ncpu hw.physicalcpu hw.logicalcpu with commands.getoutput. But ctypes is cooler and almost certainly several times faster.
