avoid opinion ... facts are your single clue. Get the facts!' - time Enough for Love, Robert Heinlein Does eating celery make you lighter? Do you have to be dying to have a near-death experience? Is a yawn a silent, natural scream for air; and if a little oxygen is good for you is more oxygen better? Can the humble spud kill? Did Galileo drop his balls from the Leaning tower of Pisa? Did a NASA computer really prove a miracle in the Bible actually happened? Is there any substance harder than diamond, and do diamonds really last forever? And exactly how many Eskimo words for 'snow' are there? Wherever he goes, people always ask Dr Karl to explain stuff, and in this his 26th book (26 is the only number directly between a square and a cube), he explains more myths and curly questions.

    Years-long drought coupled with relentless dust storms wreaked havoc on the Great Plains region and forced the American people to dig deep within in order to persevere and survive.Droughts & Dreams contains intimate family stories from that generation. Many are first-hand accounts of people who not only survived, but who also did it well. Tucked inside these pages, you’ll find timeless survival lessons, tips and even favorite from-scratch recipes.The memoirs in this book are not dreary recollections of the disgruntled. Rather, they are honest tales of families rediscovering how to live simply, be self-reliant and appreciate what they had.Perhaps 80-year old Jack Bolkovak stated it best when he said, “The Depression was a tough time. But it was a great beginning to life. It taught us that life is not easy and to appreciate all that we have. We had food, clothing, shelter and a loving family. That was all we needed.” “Those who don’t know history are doomed to repeat it.”-Edmund Burke

    We are living in an age where data comes in abundance, and thanks to the self-learning algorithms from the field of machine learning, we can turn this data into knowledge. Automated speech recognition on our smart phones, web search engines, e-mail spam filters, the recommendation systems of our favorite movie streaming services – machine learning makes it all possible.Thanks to the many powerful open-source libraries that have been developed in recent years, machine learning is now right at our fingertips. Python provides the perfect environment to build machine learning systems productively.This book will teach you the fundamentals of machine learning and how to utilize these in real-world applications using Python. Step-by-step, you will expand your skill set with the best practices for transforming raw data into useful information, developing learning algorithms efficiently, and evaluating results.You will discover the different problem categories that machine learning can solve and explore how to classify objects, predict continuous outcomes with regression analysis, and find hidden structures in data via clustering. You will build your own machine learning system for sentiment analysis and finally, learn how to embed your model into a web app to share with the world

    With this practical book, you'll explore text-mining techniques with tidytext, a package that authors Julia Silge and David Robinson developed using the tidy principles behind R packages like ggraph and dplyr. You'll learn how tidytext and other tidy tools in R can make text analysis easier and more effective.The authors demonstrate how treating text as data frames enables you to manipulate, summarize, and visualize characteristics of text. You'll also learn how to integrate natural language processing (NLP) into effective workflows. Practical code examples and data explorations will help you generate real insights from literature, news, and social media.Learn how to apply the tidy text format to NLPUse sentiment analysis to mine the emotional content of textIdentify a document's most important terms with frequency measurementsExplore relationships and connections between words with the ggraph and widyr packagesConvert back and forth between R's tidy and non-tidy text formatsUse topic modeling to classify document collections into natural groupsExamine case studies that compare Twitter archives, dig into NASA metadata, and analyze thousands of Usenet messages

    As a modern application developer you need to understand the emerging field of data management, both RDBMS and NoSQL. Seven Databases in Seven Weeks takes you on a tour of some of the hottest open source databases today. In the tradition of Bruce A. Tate's Seven Languages in Seven Weeks, this book goes beyond your basic tutorial to explore the essential concepts at the core each technology. Redis, Neo4J, CouchDB, MongoDB, HBase, Riak and Postgres. With each database, you'll tackle a real-world data problem that highlights the concepts and features that make it shine. You'll explore the five data models employed by these databases-relational, key/value, columnar, document and graph-and which kinds of problems are best suited to each. You'll learn how MongoDB and CouchDB are strikingly different, and discover the Dynamo heritage at the heart of Riak. Make your applications faster with Redis and more connected with Neo4J. Use MapReduce to solve Big Data problems. Build clusters of servers using scalable services like Amazon's Elastic Compute Cloud (EC2). Discover the CAP theorem and its implications for your distributed data. Understand the tradeoffs between consistency and availability, and when you can use them to your advantage. Use multiple databases in concert to create a platform that's more than the sum of its parts, or find one that meets all your needs at once.Seven Databases in Seven Weeks will take you on a deep dive into each of the databases, their strengths and weaknesses, and how to choose the ones that fit your needs.What You Need: To get the most of of this book you'll have to follow along, and that means you'll need a *nix shell (Mac OSX or Linux preferred, Windows users will need Cygwin), and Java 6 (or greater) and Ruby 1.8.7 (or greater). Each chapter will list the downloads required for that database.

    You’ve deloaded, done your recovery session, even taken a hot bath. Oh how nice a massage would be right now. The problem is not all of us have the time or the money to invest in some good soft tissue work. Want a cheap yet extremely effective way to get rid of your aches and pains? This easy to understand guide will help you address all of those problems and more. Best of all, you don't even need to leave your house or buy any expensive tool. Just grab a tennis ball and get started.Being able to treat your own pain is a very valuable tool. It can save you a lot of money and mean less trips to the physiotherapist as well as ensuring that you are keeping your body in good condition. Trigger points and tight muscles are a common cause of muscle and joint pain. They can refer pain to other areas as well as causing problems at the site itself. Although they don't count for all the pain you might be suffering from, releasing them can certainly help get rid of a lot of the pain, if not clear up your problem entirely. Have you ever been to the doctor and he or she told you that theres nothing wrong, even after extensive scans? You might simply need some work on your muscles. Keeping the muscle tissue quality high will help reduce the amount of injuries you suffer from, improve your posture as well as help a lot of muscle and joint pain.In this book you can learn how to effectively get rid of shoulder pain, neck pain, upper and lower back pain, hip and glute pain and stiffness, leg and knee pain, calf pain, ankle stiffness, Achilles problems and much more.Actual excerpt from the book of how I discovered this great technique."When I was playing in Germany, I had really bad shoulder pain. The kind that ran down to my fingers and made me unable to put my arms over my head. One night trying to get relief I grabbed my old Motorola and started laying on it, with it digging in under my shoulder. Slowly and excruciatingly I released the rotator cuff muscles and gave myself a pain free range of motion that I had only dreamed of before. Needless to say, I thought I was a genius and upgraded to a tennis ball pretty quickly."
