What is the cloud? How does the cloud work? What does it mean when something is 'in the cloud'? And why is it called ‘the cloud’ anyway?When you hear about the cloud, do you get a little anxious because you don’t know what the cloud is? If you do...no wonder! We hear about the cloud all the time these days. It’s everywhere! What does it mean! Let’s slow down. Take a deep breath. That’s good. Take another. Excellent. This book answers all your questions.I’ll let you in on a little secret: the cloud is not that hard to understand. It’s not. It’s just that nobody has taken the time to explain to you what the cloud is. They haven’t, have they?Deep down I think this is because they don’t understand the cloud either, but I do. I’ve been a programmer and writer for over 30 years. I’ve been in cloud computing since the very start, and I’m here to help you on your journey to understand the cloud. Consider me your tour guide. I’ll be with you every step of the way, but not in a creepy way.When you finish reading this book, you’ll understand what the cloud is and what it means for something to be in the cloud. That’s a promise.How do I deliver on that promise? I use lots and lots of pictures. I use lots and lots of examples. We’ll dive into the inner workings of Facebook Messenger, Amazon Kindle, Apple iCloud, Google Maps, and cloud DVRs. You’ll learn by seeing and understanding.Here’s the test I’ll use at the end of the book to see if I delivered on my promise of explaining the cloud:If you overhear in a café, “I just signed up for Tulip, it’s an awesome new cloud dating service,” do you understand what that means now? I hope it does. Here’s what I hope pops into your mind:• I know what a cloud is: a cloud is just a bunch of computers in a datacenter. • I know what a decanter is: a datacenter is a giant warehouse-sized building containing lots and lots of computers.• I know what a service is: a service is a job I hire someone to do for me.• I know what a cloud service is: a cloud service performs a job for me in a cloud. • What service is being performed for me? Well, Tulip is a dating service, so the service must be related to dating.• I know I’m going to access Tulip using one of my devices, like my phone, tablet, or on my computer using a web browser. • I know the cloud is a separate place, it’s not on my device, I access the cloud over the internet using an app or web site. • I know what the internet is: the internet is an electronic highway system for sending data from one computer to another computer.• I know what data is: data is a record of stuff. Anything an app understands how to do something with—is data.• I know that I’ll have to download Tulip’s app onto my device to use their cloud service. • I know I’ll use the Tulip app to perform some job for me, like hook me up with a delicious date. My request to find a date will be sent, as data, over the internet to a computer in Tulip’s cloud.• I know Tulip may have created their own cloud or they might have rented cloud services from a cloud provider.• I know a computer in Tulip’s cloud will receive my request to find a date. It will do the work of matching my profile to a list of worthy candidates. It will return the list, over the internet, to Tulip’s app. The app will display my matches and so I can reject them.• I know all my dating data is mostly safe in the cloud.• I know I can access Tulip from anywhere there’s an internet connection. • I know I can access Tulip from any device that can run Tulip’s app.• I know the dating service, because it’s in the cloud, has a lot of available compute power so it can find me the best match possible.• Hey, I know a lot about the cloud now. Yay!If you have thoughts like these, then I did my job and fulfilled my promise.

For Fun and Profit: A History of the Free and Open Source Software Revolution (History of Computing)
In the 1980s, there was a revolution with far-reaching consequences -- a revolution to restore software freedom. In the early 1980s, after decades of making source code available with programs, most programmers ceased sharing code freely. A band of revolutionaries, self-described "hackers," challenged this new norm by building operating systems with source code that could be freely shared. In For Fun and Profit, Christopher Tozzi offers an account of the free and open source software (FOSS) revolution, from its origins as an obscure, marginal effort by a small group of programmers to the widespread commercial use of open source software today. Tozzi explains FOSS's historical trajectory, shaped by eccentric personalities -- including Richard Stallman and Linus Torvalds -- and driven both by ideology and pragmatism, by fun and profit.Tozzi examines hacker culture and its influence on the Unix operating system, the reaction to Unix's commercialization, and the history of early Linux development. He describes the commercial boom that followed, when companies invested billions of dollars in products using FOSS operating systems; the subsequent tensions within the FOSS movement; and the battles with closed source software companies (especially Microsoft) that saw FOSS as a threat. Finally, Tozzi describes FOSS's current dominance in embedded computing, mobile devices, and the cloud, as well as its cultural and intellectual influence.

Today, machine learning underlies a range of applications we use every day, from product recommendations to voice recognition -- as well as some we don't yet use everyday, including driverless cars. It is the basis of the new approach in computing where we do not write programs but collect data; the idea is to learn the algorithms for the tasks automatically from data. As computing devices grow more ubiquitous, a larger part of our lives and work is recorded digitally, and as "Big Data" has gotten bigger, the theory of machine learning -- the foundation of efforts to process that data into knowledge -- has also advanced. In this book, machine learning expert Ethem Alpaydin offers a concise overview of the subject for the general reader, describing its evolution, explaining important learning algorithms, and presenting example applications.Alpaydin offers an account of how digital technology advanced from number-crunching mainframes to mobile devices, putting today's machine learning boom in context. He describes the basics of machine learning and some applications; the use of machine learning algorithms for pattern recognition; artificial neural networks inspired by the human brain; algorithms that learn associations between instances, with such applications as customer segmentation and learning recommendations; and reinforcement learning, when an autonomous agent learns act so as to maximize reward and minimize penalty. Alpaydin then considers some future directions for machine learning and the new field of "data science," and discusses the ethical and legal implications for data privacy and security.

“As an author, editor, and publisher, I never paid much attention to the competition—except in a few cases. This is one of those cases. The UNIX System Administration Handbook is one of the few books we ever measured ourselves against.” —Tim O’Reilly, founder of O’Reilly Media “This edition is for those whose systems live in the cloud or in virtualized data centers; those whose administrative work largely takes the form of automation and configuration source code; those who collaborate closely with developers, network engineers, compliance officers, and all the other worker bees who inhabit the modern hive.” —Paul Vixie, Internet Hall of Fame-recognized innovator and founder of ISC and Farsight Security “This book is fun and functional as a desktop reference. If you use UNIX and Linux systems, you need this book in your short-reach library. It covers a bit of the systems’ history but doesn’t bloviate. It’s just straight-forward information delivered in a colorful and memorable fashion.” —Jason A.
