MQTT Essentials - A Lightweight IoT Protocol
￥71.93
This step-by-step guide will help you gain a deep understanding of the lightweight MQTT protocol. We’ll begin with the specific vocabulary of MQTT and its working modes, followed by installing a Mosquitto MQTT broker. Then, you will use best practices to secure the MQTT Mosquitto broker to ensure that only authorized clients are able to publish and receive messages. Once you have secured the broker with the appropriate configuration, you will develop a solution that controls a drone with Python. Further on, you will use Python on a Raspberry Pi 3 board to process commands and Python on Intel Boards (Joule, Edison and Galileo). You will then connect to the MQTT broker, subscribe to topics, send messages, and receive messages in Python. You will also develop a solution that interacts with sensors in Java by working with MQTT messages. Moving forward, you will work with an asynchronous API with callbacks to make the sensors interact with MQTT messages. Following the same process, you will develop an iOS app with Swift 3, build a website that uses WebSockets to connect to the MQTT broker, and control home automation devices with HTML5, JavaScript code, Node.js and MQTT messages What you will learn ?Understand how MQTTv3.1 and v3.1.1 works in detail ?Install and secure a Mosquitto MQTT broker by following best practices ?Design and develop IoT solutions combined with mobile and web apps that use MQTT messages to communicate ?Explore the features included in MQTT for IoT and Machine-to-Machine communications ?Publish and receive MQTT messages with Python, Java, Swift, JavaScript, and Node.js ?Implement the security best practices while setting up the MQTT Mosquitto broker
Behind the Scenes (Downton Abbey Shorts, Book 11)
￥11.77
This richly illustrated short, extracted from the official book The Chronicles of Downton Abbey peels back the curtain on the making of Series 3. With a foreword from Downton Abbey creator Julian Fellowes. You’ll have privileged access to the on-set jokes and camaraderie between the actors – including anecdotes about Jim Carter’s (Carson’s) magic tricks and a revelation that two actors liked to burst into an impromptu duet of the Three Degrees classic “When Will I See You Again” between takes – find out who! See also how the sets at Highclere Castle and Ealing Studios were adapted, and hear from the costume and make up artists about the incredible attention to detail they applied to bring the 1920s so vividly to life. Purchase this ebook short and the others in the series to get closer still to the characters at Downton Abbey and to understand more about their social context – from the changing role of the aristocracy to fashion and beauty, American Anglophiles, the Suffragette movement and life below stairs in a big country house like Downton. Search for The Chronicles of Downton Abbey to purchase all shorts combined.

Poetry I: The Writers Call
￥0.01
"Reaches into the corners of your soul and pulls out all that is beautiful." "Masterfully crafted poetry". "A powerhouse of a poetry collection." Poetry: there are times in life when nothing else will do. And at such times, you need a certain kind of poem, the kind contained in this pamphlet. Clear, simple, accessible, inspirational poetry. This is the first in a series of poetry pamphlets by a bestselling and acclaimed novelist, a short collection of ten poems with diverse forms and subjects. "Poetry should be ingested sparingly," says Orna Ross. "like any mind-altering substance. More than ten at a time is too much, I believe." These are poems you read again and again, touching as they do on all the big themes. An artist fails to see what he is creating in his life; a woman surviving genocide making meaning from maternity; an Irish wedding blessing is reworked... You'll find poems about love -- in its many manifestations. Poems about making art. Poems about life and liberty and the conditions for happiness. Poems about loss, and faith, and redemption. All delivered in direct, achingly lovely language. This is poetry in the tradition of Mary Oliver, William Stafford, Maya Angelou. The purest practice of the theory Orna Ross expounds in her "Go Creative!" books.
