Reviews
"My method of study i chose to read this textbook cover to cover, taking all practice tests at the end of each chapter, along with the included practice exams on the disc. In addition to this text i went further to find online practice exams and Professor Messer videos on Youtube as free self studying material. The book covered the objectives and even went beyond which is why this makes a great on-the-job reference."
"First off, let me say this, the author of this book is very informed on IT."
"Most importantly, I was looking for a book that could not only keep me engaged yet also provide the necessary educational materials. Presently I'm over a hundred or so pages in (the book is Bible thick) and have purposely slowed myself down at times to ensure lesson absorption but honestly could read this book like it was a spellbinding work of fanciful fiction. It really helps to have an actual, honest interest in the subject matter and there are times where you'll want access to several different operating systems."
"Just started, but it has been an easy to follow book so far."
"Nice book for those people who like to learn as they go."
"Must have to get certified."
"I found the CD to be the best part of the book, and definitely recommend not getting a version of this book without it."
"I know a lot about computers and learned a bit to go and write the A+, but it's very good I bought this books, learnt so many additional stuff, not even for the exams but for myself m. Thank you Meyers💪🔥."

Programming Arduino: Getting Started with Sketches, Second Edition (Tab)
You will learn how to configure hardware and software, develop your own sketches, work with built-in and custom Arduino libraries, and explore the Internet of Things—all with no prior programming experience required! Simon Monk has a degree in cybernetics and computer science and a Ph.D. in software engineering.
Reviews
"Keep in mind, if you are new to Arduino programming, that most sketches (what the Arduino folks call Arduino programs) make use of libraries that you can download."
"Unfortunately, the usual books for "helping" with Arduino give sketches and explain bits and pieces without ever doing an overview of the system. Just got it today and have read over half of it; I've marked it up with pen to remind myself of crucial facts that I wish I had known a few months back. It's written at just the right level for beginners who are just learning about Arduino and microprocessors in general, and he points you to all the resources on the web for further information. So instead of having to copy and paste everyone else's code all the time, read this book to understand at least the basics of WHY things work in an Arduino the way they do."
"Easy to understand and get familiar with Arduino world."
"I got this for a friend who had just started assembling boards using Adruino."
"Too many other books and tutorials just tell you to build a circuit and watch it do it's thing without explaining why it does it and how to expand on that design. I look forward to starting the "Next Steps" sequal and continuing to learn what this little chunk of organized metal and plastic has in store."
"I'm brand new to Arduino, but I've been programming for 30 years."
"Good starting place for working with Arduino."
"Purchased for my 14 yo grandson who is into dp stuff."

Best Two-Hour Computers & Technology Short Reads

Machine Learning With Random Forests And Decision Trees: A Visual Guide For Beginners
Most books, and other information on machine learning, that I have seen fall into one of two categories, they are either textbooks that explain an algorithm in a way similar to "And then the algorithm optimizes this loss function" or they focus entirely on how to set up code to use the algorithm and how to tune the parameters. An overview of decision trees and random forests A manual example of how a human would classify a dataset, compared to how a decision tree would work How a decision tree works, and why it is prone to overfitting How decision trees get combined to form a random forest How to use that random forest to classify data and make predictions How to determine how many trees to use in a random forest Just where does the "randomness" come from Out of Bag Errors & Cross Validation - how good of a fit did the machine learning algorithm make? Gini Criteria & Entropy Criteria - how to tell which split on a decision tree is best among many possible choices And More.
Reviews
"I use Random Forests in my research and I wanted to have a better intuition and understanding of how this technique works."
"Great overview with sample code!"
"Still a very good read and I look forward to reading more of Mr Hartshorn's works."
"This book is a very good introduction on the topic, presenting, with well chosen examples, the most important concepts of machine learning."
"This is an excellent strategy because it covers all the essentials, while still leaving you enough time to dig into some application or play with a build as you go along (which is ultimately the point)."
"Now I can use random forest because I know the concept behind the algorithm."
"Previously, I have seen one or two useful diagrams in the scikit learn examples, illustrating the splitting result, but the author takes this idea to a whole new level with many diagrams illustrating fitting and over-fitting."
"A good material for you to catch the main idea of random forest with some examples in a short time."

Best Matrices

Coding the Matrix: Linear Algebra through Computer Science Applications
The reader learns by doing, writing programs to implement the mathematical concepts and using them to carry out tasks and explore the applications. He has been a Visiting Scientist at Princeton’s Computer Science Department, at MIT’s Mathematics Department, and at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), where he is currently a Research Affiliate. His love for computer science has never abated, but in a chance encounter with E. W. Dijkstra in 1979, he was told that, if he wanted to do computer science, he had better learn some math.
Reviews
"I am am a retired software engineer who spent my entire career working for an aero-space research company."
"Being lazy and wanting to focus on the math, not the typing -- I downloaded the code examples from the website and that worked as advertised."
"I found this book invaluable while taking the author's course Coding the Matrix on coursera.org."
"I feel like this book covers every aspect of the theory, applies it step-by-step and does more than my semester of linear algebra to prepare the reader for applying this to real world solutions."
"I learned quite a lot by reading chapters and writing code for exercises and labs."
"The autograding system is really great, except that it's not complete yet!"
"A really great book that approaches linear algebra from a different angle."
"As many other readers have noted going back several years, the 1st edition of this book had an over abundance of typographical errors which have been corrected in more recent print versions. Amazon has cheapened the Kindle brand by selling old versions of books and tagging them with recent publication dates."

Reviews
"I purchased “Amazon Echo: Master Your Amazon Echo; User Guide and Manual because I wanted more detailed information about my wife’s new Echo device than the rather sparse manual that came with it provided. This book is essential if you own an Amazon Echo (with built-in speaker system)."
"However I love the Echo so much that I bought several as Christmas presents and just knew that my tech challenged parents would be calling me every 2 minutes asking for help."
"Though I had read some user guidebook before to learn more about Amazon Echo, but I grabbed this new version book for the sake of knowing all the latest things that were added in this device."
"I would definitely recommend this book to everyone who thinks that he or she is very new to Amazon Echo and could need a "guiding hand". through the process."
"I purchased it at the same time I purchased my Echo, and they arrived together."
"Excellent!"
"This guide was highly informative, easily understood and had everything a beginner needs to know about getting started with Amazon Echo and more."
"Just bought an Echo 2 only to find out there is no owners manual provided by Amazon. Well book says Echo has two buttons on top. Manual says Echo comes with remote (what's in the box?)."

"Bought this and read through it before getting my New MacBook, it made the MacBook a lot easier to navigate."
"Just what I needed since I am a microsoft user for 20+ years."
"I bought this after buying my Mac Book Pro."
"So far this is everything that the MacBook Dummies book is not: the pages are glossy, there are lots of color diagrams and photos, and it is specific to the MacBook Pro, so there isn't lots of extraneous information to deal with. For someone like me, The Teach Yourself Visually MacBook Pro book is ideal, and purchasing this MacBook for Dummies book was a mistake."
"Bought this for my hubby who just got a Mac."
"This book is easy to read and follow but most of the info is not very usable as I still had to go to the Apple store for assistance."
"Did not serve my needs at all."
