New Website “Is It Really FOSS?” Tracks Transparency in Open Source Distribution Models
A new site reviews software projects to reveal if they’re truly FOSS, making complex licensing and distribution models easy to understand.
This gem adds MQTT (Message Queue Telemetry Transport) protocol support to EventMachine, an event-processing library for Ruby.
You may get the latest stable version from rubygems.org:
$ gem install em-mqtt
It depends upon the mqtt gem to perform packet parsing and serialising.
require 'rubygems'
require 'em/mqtt'
# Publish example
EventMachine.run do
c = EventMachine::MQTT::ClientConnection.connect('test.mosquitto.org')
EventMachine::PeriodicTimer.new(1.0) do
puts "-- Publishing time"
c.publish('test', "The time is #{Time.now}")
end
end
# Subscribe example
EventMachine.run do
EventMachine::MQTT::ClientConnection.connect('test.mosquitto.org') do |c|
c.subscribe('test')
c.receive_callback do |message|
p message
end
end
end
