Heater
POD
NAME
App::Heater - Raku-based Foot Warmer
SYNOPSIS
my $heater = App::Heater.new; $heater.heat;
DESCRIPTION
This program was written during a period of brutally cold weather, when the author was trying to figure out how to keep her feet warm. Since her computer is on the floor by her feet, and because she knows that the busier the CPU, the more heat generated, she wrote this module to load up the CPU.
CAVEATS
Obviously your electrical usage footprint (no pun intended) will increase if you run this program. That said, I believe this program is only slightly less efficient to turn your computer into a space heater than an actual space heater of the same wattage would be (I.E. energy used for "useful work" on the computer like sending signals to your monitor or lighting the power LED would not be turned into heat, while an electric space heater has even less of these "housekeeping" functions). In practice, I believe the energy difference to be negligable.
Only use this if your feet are cold!
USAGE
ATTRIBUTES
processes
$heater.processes = 3; say "Heating using " ~ $heater.processes;
Determines the number of "heater" threads to start. This defaults to the
number of CPU cores in the machine, determined by $*KERNEL.cpu-cores.
METHODS
heat
$heater.heat;
This starts the heater. It will continue running until the process is killed, usually with a control-C character. When possible, the program will attempt to run "nicely," I.E. at a CPU priority below interactive programs, to not interfere with the overall performance of the machine.
start-heat-threads
$heater.start-heat-threads;
This starts the background heat threads. Note that it will not adjust the process CPU priority, and will immedaitely (or close to it) return, leaving the threads running in the background. Multiple calls will execute the heater threads multiple times.
