A primer on the underlying technologies that allow computer programs to work. Covers topics like computer hardware, combinatorial logic, sequential logic, computer architecture, computer anatomy, and Input/Output. Many coders are unfamiliar with the underlying technologies that make their programs run. But why should you care when your code appears to work? Because you want it to run well and not be riddled with hard-to-find bugs. You don't want to be in the news because your code had a security problem. Lots of technical detail is available online but it's not organized or collected into a convenient place. In The Secret Life of Programs, veteran engineer Jonathan E. Steinhart explores--in depth--the foundational concepts that underlie the machine. Subjects like computer hardware, how software behaves on hardware, as well as how people have solved problems using technology over time. You'll learn: How the real world is converted into a form that computers understand, like bits, logic, numbers, text, and colors The fundamental building blocks that make up a computer including logic gates, adders, decoders, registers, and memory Why designing programs to match computer hardware, especially memory, improves performance How programs are converted into machine language that computers understand How software building blocks are combined to create programs like web browsers Clever tricks for making programs more efficient, like loop invariance, strength reduction, and recursive subdivision The fundamentals of computer security and machine intelligence Project design, documentation, scheduling, portability, maintenance, and other practical programming realities. Learn what really happens when your code runs on the machine and you'll learn to craft better, more efficient code.

Computer programming is not abstract and programs run on a machine. Knowing how computers work and how programs run on them is essential to becoming a better programmer, and understanding underlying technologies can help you develop a sense of what can go wrong. The Secret Life of Programs (formerly Foundations of Computer Programming) fills in the gaps in computer education by giving readers a look under the hood of programming, at the machine. Readers learn how software behaves when running on hardware; how programs manipulate data in memory; how computers process languages; and how web browsers work. They'll also learn how to write efficient programs, computer security basics, and real-world considerations to have in mind when writing code.

He is one of the wisest men of all time. Since the time of the Bible, he is the only man to be celebrated by the three major Western religions of Judaism, Christianity and Islam. His name is Maimonides. A philosopher, rabbi, physician, religious thinker and logician, today this sage is considered among the greatest thinkers. The Secret Life reveals his ancient teachings in modern terms. In The Secret Life, you will discover true wisdom and success in every aspect of life comes not from our public persona and life -- as so many believe -- but in our secret thoughts and actions. Maimonides shows how every person can find their true and best self, not only deriving happiness for themselves, but spreading that bliss to everyone they touch. The benefits of living the Secret Life are countless. Changing your approaches to giving charity, to seeking justice, to loving others, and to believing in yourself enough to find and act on your true calling will lead you to remarkable heights. You will find a new resilience against the difficulties and turmoil in life, a new inner power that will keep you focused on the things that really matter, and an inner peace few will ever have. The Secret Life is, quite literally, life changing. "Whatever you do should be done out of nothing else but pure love." -- Maimonides Jeffrey Katz is a lifelong student and teacher of rationalist religious philosophy. He became fascinated in his youth by his discovery of the ancient wisdom of Maimonides, and received rabbinic ordination while focusing on disseminating the ancient, life-changing wisdom he had uncovered. He is a practicing attorney, has appeared on national television on a broad range of issues, and has lectured widely.

A surprising and entertaining explanation of how the words we use (even the ones we don't notice) reveal our personalities, emotions, and identities. We spend our lives communicating. In the last fifty years, we've zoomed through radically different forms of communication, from typewriters to tablet computers, text messages to tweets. We generate more and more words with each passing day. Hiding in that deluge of language are amazing insights into who we are, how we think, and what we feel. In The Secret Life of Pronouns, social psychologist and language expert James W. Pennebaker uses his groundbreaking research in computational linguistics-in essence, counting the frequency of words we use-to show that our language carries secrets about our feelings, our self-concept, and our social intelligence. Our most forgettable words, such as pronouns and prepositions, can be the most revealing: their patterns are as distinctive as fingerprints. Using innovative analytic techniques, Pennebaker X-rays everything from Craigslist advertisements to the Federalist Papers-or your own writing, in quizzes you can take yourself-to yield unexpected insights. Who would have predicted that the high school student who uses too many verbs in her college admissions essay is likely to make lower grades in college? Or that a world leader's use of pronouns could reliably presage whether he led his country into war? You'll learn why it's bad when politicians use "we" instead of "I," what Lady Gaga and William Butler Yeats have in common, and how Ebenezer Scrooge's syntax hints at his self-deception and repressed emotion. Barack Obama, Sylvia Plath, and King Lear are among the figures who make cameo appearances in this sprightly, surprising tour of what our words are saying-whether we mean them to or not.
