    This concise introduction shows you how to perform statistical analysis computationally, rather than mathematically, with programs written in Python.You'll work with a case study throughout the book to help you learn the entire data analysis process—from collecting data and generating statistics to identifying patterns and testing hypotheses. Along the way, you'll become familiar with distributions, the rules of probability, visualization, and many other tools and concepts.Develop your understanding of probability and statistics by writing and testing codeRun experiments to test statistical behavior, such as generating samples from several distributionsUse simulations to understand concepts that are hard to grasp mathematicallyLearn topics not usually covered in an introductory course, such as Bayesian estimationImport data from almost any source using Python, rather than be limited to data that has been cleaned and formatted for statistics toolsUse statistical inference to answer questions about real-world data

    You want to learn HTML so you can finally create those web pages you've always wanted, so you can communicate more effectively with friends, family, fans, and fanatic customers. You also want to do it right so you can actually maintain and expand your Web pages over time, and so your web pages work in all the browsers and mobile devices out there. Oh, and if you've never heard of CSS, that's okay - we won't tell anyone you're still partying like it's 1999 - but if you're going to create Web pages in the 21st century then you'll want to know and understand CSS.Learn the real secrets of creating Web pages, and why everything your boss told you about HTML tables is probably wrong (and what to do instead). Most importantly, hold your own with your co-worker (and impress cocktail party guests) when he casually mentions how his HTML is now strict, and his CSS is in an external style sheet.With Head First HTML with CSS & XHTML, you'll avoid the embarrassment of thinking web-safe colors still matter, and the foolishness of slipping a font tag into your pages. Best of all, you'll learn HTML and CSS in a way that won't put you to sleep. If you've read a Head First book, you know what to expect: a visually-rich format designed for the way your brain works. Using the latest research in neurobiology, cognitive science, and learning theory, this book will load HTML, CSS, and XHTML into your brain in a way that sticks.So what are you waiting for?

    This book is neither a step-by-step tutorial nor a reference book. Instead, our goal is to bring a diverse set of software engineering topics together into a single narrative, help readers understand the most important ideas through concrete examples and a learn-by-doing approach, and teach readers enough about each topic to get them started in the field. Courseware for doing the work in the book is available as a virtual machine image that can be downloaded or deployed in the cloud. A free MOOC (massively open online course) at saas-class.org follows the book's content and adds programming assignments and quizzes. See http://saasbook.info for details.

    Things are bound to get hot when the men of Crimson Security are involved. Book 1 My name is Darby Connors and I’m in deep. Maybe too deep for me to make it out alive. It isn’t the first time I’ve been in trouble while doing my job, but this time feels different. Something is coming for me. Someone is coming for me. Hendrix Crimson is assigned to guard my body, and guard it, he does. Caught up in the mess I’ve made, he tries to help me solve the case I’m working on so he only has to worry about one killer coming after me. Book 2 My name is Lacey Holt and I do not need help from Jagger Crimson. Someone is messing with my family, and my ranch, trying to drag up painful family memories. They’ve convinced my dad that my brother’s murderer is back and ready to pick off the rest of our family. I know better. I know that I can take care of it without Jagger, too. He’s a constant distraction and all he’ll do is get in my way. Convincing my dad of that is another story. When it becomes clear that the threat is directed at me, he is ready to ship me off to safety. I’m an adult, though. I’m tough. There’s nothing that this hidden bully can do to run me off my family land. Except for kidnap me and lock me away. So, maybe I do need Jagger after all. Not that I’d ever want to admit that to him. Book 3 Left an orphan after a rough childhood, I was taken in by the president of a rough Motorcycle Club. Given plenty of room to grow, I was treated like a princess. Until I wasn’t. When things in the club change and a new president takes his throne, I’m in more danger than ever. Sold and then saved by Jackson, I owe him my life. It’s not anything he’s interested in, though. Jackson comes with baggage, but I get it. I have my own. Who can help that when we unpack it, things get a little messy? Book 4 I’m not who I used to be. Detective Rain Willows died while being held captive by a very bad man. Now, I don’t know who I am. I’m not a cop. I’m barely a human some days. I’m scared. I lost everything. I gained some scars. The bad man is still after me. Thad Brooks has an ax to grind with me, but he feels like the only thing standing between me and death. I don’t want to admit that I’m afraid, or that I need help, but when things get bad enough, I’m not too stubborn to wave the white flag. Book 5 My only desire in life is to get my daughter back. At any cost, including my life. My name is Clara Crimson and I’m not a good person. I live with a monster and I have killed. I don’t deserve to be happy, but she does. Cash Crimson, my ex-husband, has every reason to hate me and he does. He probably would like to watch me die, but he thinks he needs me to find our daughter. What we find isn’t what we expected, though. I’m not sure either of us will survive it. I’m not sure I want to. We have to keep our daughter safe. We have to get close and remember we’re on the same team. It's time to bring down the man who destroyed us.
