    The algorithms you'll use most often as a programmer have already been discovered, tested, and proven. If you want to take a hard pass on Knuth's brilliant but impenetrable theories and the dense multi-page proofs you'll find in most textbooks, this is the book for you. This fully-illustrated and engaging guide makes it easy for you to learn how to use algorithms effectively in your own programs.Grokking Algorithms is a disarming take on a core computer science topic. In it, you'll learn how to apply common algorithms to the practical problems you face in day-to-day life as a programmer. You'll start with problems like sorting and searching. As you build up your skills in thinking algorithmically, you'll tackle more complex concerns such as data compression or artificial intelligence. Whether you're writing business software, video games, mobile apps, or system utilities, you'll learn algorithmic techniques for solving problems that you thought were out of your grasp. For example, you'll be able to:Write a spell checker using graph algorithmsUnderstand how data compression works using Huffman codingIdentify problems that take too long to solve with naive algorithms, and attack them with algorithms that give you an approximate answer insteadEach carefully-presented example includes helpful diagrams and fully-annotated code samples in Python. By the end of this book, you will know some of the most widely applicable algorithms as well as how and when to use them.

To be successful at day trading you need the right tools and you need to be motivated, to work hard, and to persevere.At the beginning of my trading career, a pharmaceutical company announced some positive results for one of its drugs and its stock jumped from $1 to over $55 in just two days. Two days! I was a beginner at the time. I was the amateur. I purchased 1,000 shares at $4 and sold them at over $10. On my very first beginner trade, I made $6,000 in a matter of minutes.It was pure luck. I honestly had no idea what I was doing. Within a few weeks I had lost that entire $6,000 by making mistakes in other trades. I was lucky. My first stupid trade was my lucky one. Other people are not so lucky. For many, their first mistake is their last trade because in just a few minutes, in one simple trade, they lose all of the money they had worked so hard for. With their account at zero, they walk away from day trading.As a new day trader you should never lose sight of the fact that you are competing with professional traders on Wall Street and other experienced traders around the world who are very serious, highly equipped with advanced education and tools, and most importantly, committed to making money.In How to Day Trade for a Living, I will show you how you too can take control over your life and have success in day trading on the stock market.

    Previously undocumented, these 23 patterns allow designers to create more flexible, elegant, and ultimately reusable designs without having to rediscover the design solutions themselves.The authors begin by describing what patterns are and how they can help you design object-oriented software. They then go on to systematically name, explain, evaluate, and catalog recurring designs in object-oriented systems. With Design Patterns as your guide, you will learn how these important patterns fit into the software development process, and how you can leverage them to solve your own design problems most efficiently. Each pattern describes the circumstances in which it is applicable, when it can be applied in view of other design constraints, and the consequences and trade-offs of using the pattern within a larger design. All patterns are compiled from real systems and are based on real-world examples. Each pattern also includes code that demonstrates how it may be implemented in object-oriented programming languages like C++ or Smalltalk.

    If you are seriously interested in understanding how you and your team can start down the path of improvement with XP, you must read this book."-- Francesco Cirillo, Chief Executive Officer, XPLabs S.R.L. "The first edition of this book told us what XP was--it changed the way many of us think about software development. This second edition takes it farther and gives us a lot more of the 'why' of XP, the motivations and the principles behind the practices. This is great stuff. Armed with the 'what' and the 'why, ' we can now all set out to confidently work on the 'how' how to run our projects better, and how to get agile techniques adopted in our organizations."-- Dave Thomas, The Pragmatic Programmers LLC "This book is dynamite! It was revolutionary when it first appeared a few years ago, and this new edition is equally profound. For those who insist on cookbook checklists, there's an excellent chapter on 'primary practices, ' but I urge you to begin by truly contemplating the meaning of the opening sentence in the first chapter of Kent Beck's book: 'XP is about social change.' You should do whatever it takes to ensure that every IT professional and every IT manager--all the way up to the CIO--has a copy of Extreme Programming Explained on his or her desk."-- Ed Yourdon, author and consultant "XP is a powerful set of concepts for simplifying the process of software design, development, and testing. It is about minimalism and incrementalism, which are especially useful principles when tackling complex problems that require a balance of creativity and discipline."-- Michael A. Cusumano, Professor, MIT Sloan School of Management, and author of The Business of Software " Extreme Programming Explained is the work of a talented and passionate craftsman. Kent Beck has brought together a compelling collection of ideas about programming and management that deserves your full attention. My only beef is that our profession has gotten to a point where such common-sense ideas are labeled 'extreme.'..."-- Lou Mazzucchelli, Fellow, Cutter Business Technology Council "If your organization is ready for a change in the way it develops software, there's the slow incremental approach, fixing things one by one, or the fast track, jumping feet first into Extreme Programming. Do not be frightened by the name, it is not that extreme at all. It is mostly good old recipes and common sense, nicely integrated together, getting rid of all the fat that has accumulated over the years."-- Philippe Kruchten, UBC, Vancouver, British Columbia "Sometimes revolutionaries get left behind as the movement they started takes on a life of its own. In this book, Kent Beck shows that he remains ahead of the curve, leading XP to its next level. Incorporating five years of feedback, this book takes a fresh look at what it takes to develop better software in less time and for less money. There are no silver bullets here, just a set of practical principles that, when used wisely, can lead to dramatic improvements in software development productivity."-- Mary Poppendieck, author of Lean Software Development: An Agile Toolkit "Kent Beck has revised his classic book based on five more years of applying and teaching XP. He shows how the path to XP is both

    This is the secret that lets tiny quantitative edges create hedge fund billionaires, and defines the powerful modern global derivatives economy. The same practical techniques are still used today by risk-takers in finance as well as many other fields. "Red-Blooded Risk" examines this approach and offers valuable advice for the calculated risk-takers who need precise quantitative guidance that will help separate them from the rest of the pack. While most commentators say that the last financial crisis proved it's time to follow risk-minimizing techniques, they're wrong. The only way to succeed at anything is to manage true risk, which includes the chance of loss. "Red-Blooded Risk" presents specific, actionable strategies that will allow you to be a practical risk-taker in even the most dynamic markets.Contains a secret history of Wall Street, the parts all the other books leave outIncludes an intellectually rigorous narrative addressing what it takes to really make it in any risky activity, on or off Wall StreetAddresses essential issues ranging from the way you think about chance to economics, politics, finance, and lifeWritten by Aaron Brown, one of the most calculated and successful risk takers in the world of finance, who was an active participant in the creation of modern risk management and had a front-row seat to the last meltdownWritten in an engaging but rigorous style, with no equationsContains illustrations and graphic narrative by renowned manga artist Eric KimThere are people who disapprove of every risk before the fact, but never stop anyone from doing anything dangerous because they want to take credit for any success.

    After trying – and failing – to land a job as a journalist, he secured a trainee position at Morgan Stanley and got his first feel for the pecking order that exists in the trading pits.  Those on the “buy side,” the traders who make large bets on whether a stock will rise or fall, are the “alphas” and those on the “sell side,” the brokers who handle their business, are eager to please. How eager to please was brought home stunningly to Turney in 1999 when he arrived at the Galleon Group, a colossal hedge-fund management firm run by secretive founder Raj Rajaratnam.  Finally in a position to trade on his own, Turney was encouraged to socialize with the sell side and siphon from his new broker friends as much information as possible.  Soon he was not just vacuuming up valuable tips but also being lured into a variety of hedonistic pursuits.  Naïve enough to believe he could keep up the lifestyle without paying a price, he managed to keep an eye on his buy-and-sell charts and, meanwhile, pondered the strange goings on at Galleon, where tens of millions were being made each week in sometimes mysterious ways.  At his next positions, at Argus Partners and J.L. Berkowitz, Turney climbed to even higher heights – and, as it turned out, plummeted to even lower depths – as, by day, he solidified his reputation one of the Street’s most powerful healthcare traders, and by night, he blazed a path through the city’s nightclubs, showing off his social genius and voraciously inhaling any drug that would fill the void he felt inside. A mesmerizingly immersive journey through Wall Street’s first millennial decade, and a poignant self portrait by a young man who surely would have destroyed himself were it not for his decision to walk away from a seven-figure annual income, The Buy Side is one of the best coming-of-age-on-the-Street books ever written.
