I was just wondering if it would be alright to dual boot a machine with both UNIX using XTERM for the interface and windows 98 or if people consider this a bad idea? if you consider it bad do tell me some possible alternatives..also would it be better to get linux over pure unix?

cache::memory
Cache::Memory(3pm) User Contributed Perl Documentation Cache::Memory(3pm)NAME
Cache::Memory - Memory based implementation of the Cache interface
SYNOPSIS
use Cache::Memory;
my $cache = Cache::Memory->new( namespace => 'MyNamespace',
default_expires => '600 sec' );
See Cache for the usage synopsis.
DESCRIPTION
The Cache::Memory class implements the Cache interface. This cache stores data on a per-process basis. This is the fastest of the cache
implementations, but is memory intensive and data can not be shared between processes. It also does not persist after the process dies.
However data will remain in the cache until cleared or it expires. The data will be shared between instances of the cache object, a cache
object going out of scope will not destroy the data.
CONSTRUCTOR
my $cache = Cache::Memory->new( %options )
The constructor takes cache properties as named arguments, for example:
my $cache = Cache::Memory->new( namespace => 'MyNamespace',
default_expires => '600 sec' );
See 'PROPERTIES' below and in the Cache documentation for a list of all available properties that can be set.
METHODS
See 'Cache' for the API documentation.
PROPERTIES
Cache::Memory adds the property 'namespace', which allows you to specify a different caching store area to use from the default. All
methods will work ONLY on the namespace specified.
my $ns = $c->namespace();
$c->set_namespace( $namespace );
For additional properties, see the 'Cache' documentation.
