Intended for developers who are already familiar with the Apex language, and experienced Java and C# developers who are moving to Apex, this book starts where the Force.com documentation leaves off. Instead of trying to cover all of the features of the platform, Advanced Apex programming focuses entirely on the Apex language and core design patterns. You’ll learn how to truly think in Apex – to embrace limits and bulk patterns. You’ll see how to develop architectures for efficient and reliable trigger handling, and for asynchronous operations. You’ll discover that best practices differ radically depending on whether you are building software for a specific organization or for a managed package. And you’ll find approaches for incorporating testing and diagnostic code that can dramatically improve the reliability and deployment of Apex software, and reduce your lifecycle and support costs. Based on his experience both as a consultant and as architect of a major AppExchange package, Dan Appleman focuses on the real-world problems and issues that are faced by Apex developers every day, along with the obscure problems and surprises that can sneak up on you if you are unprepared.

Sondhi:N.K. Sondhi’s first book was 'Management of Banking', which draws upon his experiences as a manager in the Punjab National Bank. He then turned to fiction writing, bringing forth the seen and unseen aftermaths of the partition of India in 1947 in his novel 'Cart full of Husk'. He followed it up with a short non-fiction, 'Forgotten City of Delhi (How Delhi became Delhi)'. He wrote his next book, 'A Match Made in Heaven: A 2000-year-old love story', based on the life of an Indian princess, who became first queen of Korea in 48 AD.Working with young people as he pursued social activities after his retirement, he sensed the restlessness among youngsters, who are facing a large number of problems due to stiff neck to neck competition in every field of life. Growing use of advanced technology has further alienated them from the main stream of the society. This has led him to initiate this book 'Know Your Worth' with the young and enterprising writer Ms. Vibha Malhotra.-------------------------------------------------Vibha Malhotra:Vibha Malhotra is the founder of 'Literature Studio' and editor-in-chief of the literary e-journal 'Literature Studio Review'.

Stay SuccessfulINVEST IN YOURSELF Now that you know that you have superpowers that are there within you and can be harvested whenever you need them, it is important to take time to really explore all your strengths and weaknesses. Only then can you be fully prepared to achieve your goals. But we are mostly clueless that understanding ourselves doesn’t have to be a slow, tedious process, it can always be sped up.All of us are born with inherent likes and dislikes. Even a fetus in the womb has its own taste preferences, resulting in the seemingly irrational food cravings that expecting mothers experience. These preferences, likes, and dislikes are clues to the things you will be good at. If a child enjoys painting more than singing, chances are that the child will be better at painting than he/she is at singing. You can think of these as clues that nature chose to expose to us so that we can carve a satisfying path for ourselves.Most of us, even as adults, have whims, and mostly we choose to ignore them. Even as children, we are rarely able to indulge in every whim. There are always limitations – in terms of time, finances, facilities etc. – to keep us from fully exploring what we are capable of. But these are not the only factors that stop us. The biggest factor, in fact, is our own inhibitions, especially once we are grown-ups. We are afraid of new experiences, afraid of disappointment, afraid of failure, afraid of making fools of ourselves. And this fear keeps us from taking advantage of opportunities to gather new experiences. Let us try to understand this with the example of a young girl called Shikha. Shikha and the Ideation CompetitionShikha was an editor at a publishing house. She was very good at her job and apart from being an excellent editor, she also often proposed new book ideas to the publishing house.The publishing house announced a competition in which teams would work together and come up with new book ideas that they would then present to a jury comprising of senior publishers from all over the world. The selected idea would then be converted into a book that would be sold all over the world.Shikha had never ever participated in a competition, let alone won it. She wasn’t at all confident of her abilities to work in a team. And the fact that the competition was about new book ideas was making her restless. By proposing new book ideas in the past, she had earned a reputation in that area. Her colleagues and even her boss thought of her as a creative thinker. Shikha was worried that if she participated in this competition and lost it, her reputation as a creative thinker would be tarnished too. Can you guess why she was so full of doubts? It was because she had always attributed her past achievements to good luck, and had never given herself any credit for the book ideas she had come up with. Thus, she was afraid of being exposed as someone who really did not possess any great talent.She was still in this state of dilemma when she discovered that her manager had already nominated Shikha’s name for the competition. Now she had no choice, so she decided to go with the flow. With each passing day, her desperation to win the contest increased, and by the time the date of the competition arrived, she found herself unable to sleep. She knew that she would do anything to win this competition. For the first time in her life she was this passionate about something. She wanted to give it her all.On the day of the competition, she was put in a team and the team started with discussing the various ideas that all members had. Shikha had a great idea, but when she saw more merit in the idea proposed by another team member, she voted for it to be taken up for further preparation and the final presentation. She was almost feverish with excitement. And when her team members were of the opinion that they should give their best and not really care if they win or lose, Shikha was single-minded about her goal of winning the competition. Her focus proved to be contagious and soon all her team-members too were bubbling with enthusiasm. Guided by their single goal, the group of strangers really became a team and the initial idea evolved to become something they all believed in. Though the team leader was someone else, everyone could see that Shikha was the driving force for the team. When it was time to present their idea, the team leader proposed that Shikha should do it. And the presentation left the judges mesmerized. When their team emerged the winner, no one was surprised. Their idea and their presentation of it were deemed to be the best.Once she was out of the competition frenzy, Shikha herself was surprised. She couldn’t understand what had come over her during the competition. But she was glad to discover this other Shikha. She had gone into the competition based on her creative thinking, but her team had emerged a winner because of her team spirit and leadership skills. Shikha was surprised to discover these two new skills in herself. She had never thought herself capable of what she had achieved. Most of us are like Shikha – capable, but afraid of failure and public ridicule. And this is why we do not take chances in life. We like to play safe. But one can never really truly understand oneself by remaining in a shell. Unless you experience new things, you can never experience a new you. Unless you take risks, you can never transcend your normal, day-to-day existence.But, what gives us the capacity to take risks? Our confidence on our strengths and abilities. And from where do we get this confidence? Unfortunately, it isn’t a commodity and you cannot buy it from a shop. Money can’t buy you confidence. You need to work hard to develop it. You need to test yourself, which is again done by putting yourself in situations that you feel are beyond your reach. So, this is once again a chicken-and-egg situation. But after you have been through some such cycles and are confident of the situations you can handle, you are in a better position to fix your goals.However, it is easier said than done. Unfortunately, life is not a fairy tale and this means that we will not succeed every time we take up a challenge. There will also be times when we fail. This is inevitable. We will invariably have to face problems, and this may shake our confidence. Dealing with failures is not easy. It is like a double-edged sword. If you take failures too seriously, they may end up crushing you. On the other hand, if you take them too lightly, you will not learn any lessons from them, which means that the risk that you took would go to waste. So, you need to recognize failures for what they are – failures. Nothing more, nothing less. If you fail in a challenge, it does not mean that you yourself are a failure. This is the most common mistake we commit. Failing a challenge means that you failed that challenge. You need to analyze the situation, see what you could have done better, and move on to the next challenge where you can test your learnings.This act of never giving up, will give you confidence and this confidence helps us realize our capabilities. And this, in turn, shows in our personality. We hold our head high. We walk with determination. We talk with conviction, and we are normally in a good mood. Confidence also gives us perseverance – the ability to keep going after a failure. If you haven’t invested in yourself, you are more likely to give up after a failure or two.Confidence helps us stay on our path and not go astray. Many hurdles and problems may block our way and discourage us, but if we have confidence, we will not let these hurdles stop us. Instead we will search for an alternate path to our goal. The Little Bird and the BranchOnce a little bird landed on a branch high up a tall tree. The jungle below was full of dangerous predators but at this height, they posed no danger to the little bird. Feeling safe and protected, the little bird rested, enjoying the beautiful view around, and feeling completely at peace. Just as the bird became used to the branch, a strong wind started blowing, shaking the entire tree. The tree swayed with such intensity that it appeared the branch would break and fall down.To other animals, this could be a matter of great worry, but the little bird was not worried. Do you know why? Because the little bird knew its own powers and strengths. Even if the branch was to fall down, the bird knew that it had wings and the ability to fly. And the bird was also aware that if this branch was to fall, there are many other branches that could be used instead. Therefore, the bird, though tiny in size, sat on the branch, braving the high wind. The animals below, all of them much stronger than the bird, were filled with much admiration for this courageous little creature who was braving difficult circumstances. The story of this small bird tells us a lot about our own self-confidence and courage. If one road is blocked there are others we can follow. And if there are no new roads, there’s always the earth on which we can make a new road.

    How can we catch schools that cheat on standardized tests? How does Netflix know which movies you’ll like? What is causing the rising incidence of autism? As best-selling author Charles Wheelan shows us in Naked Statistics, the right data and a few well-chosen statistical tools can help us answer these questions and more.For those who slept through Stats 101, this book is a lifesaver. Wheelan strips away the arcane and technical details and focuses on the underlying intuition that drives statistical analysis. He clarifies key concepts such as inference, correlation, and regression analysis, reveals how biased or careless parties can manipulate or misrepresent data, and shows us how brilliant and creative researchers are exploiting the valuable data from natural experiments to tackle thorny questions.And in Wheelan’s trademark style, there’s not a dull page in sight. You’ll encounter clever Schlitz Beer marketers leveraging basic probability, an International Sausage Festival illuminating the tenets of the central limit theorem, and a head-scratching choice from the famous game show Let’s Make a Deal—and you’ll come away with insights each time. With the wit, accessibility, and sheer fun that turned Naked Economics into a bestseller, Wheelan defies the odds yet again by bringing another essential, formerly unglamorous discipline to life.

    Crease tells the stories behind ten of the greatest equations in human history. Was Nobel laureate Richard Feynman really joking when he called Maxwell's electromagnetic equations the most significant event of the nineteenth century? How did Newton's law of gravitation influence young revolutionaries? Why has Euler's formula been called "God's equation," and why did a mysterious ecoterrorist make it his calling card? What role do betrayal, insanity, and suicide play in the second law of thermodynamics?The Great Equations tells the stories of how these equations were discovered, revealing the personal struggles of their ingenious originators. From "1 + 1 = 2" to Heisenberg's uncertainty principle, Crease locates these equations in the panoramic sweep of Western history, showing how they are as integral to their time and place of creation as are great works of art.

    But they've often been hidden in plain sight, their inventions and contributions touching our lives in ways we don't even realize.Author Claire L. Evans finally gives these unsung female heroes their due with her social history of the Broad Band, the women who made the internet what it is today. Learn from Ada Lovelace, the daughter of Lord Byron, who wove numbers into the first program for a mechanical computer in 1842. Seek inspiration from Grace Hopper, the tenacious mathematician who democratized computing by leading the charge for machine-independent programming languages after World War II. Meet Elizabeth "Jake" Feinler, the one-woman Google who kept the earliest version of the Internet online, and Stacy Horn, who ran one of the first-ever social networks on a shoestring out of her New York City apartment in the 1980s. Evans shows us how these women built and colored the technologies we can't imagine life without.Join the ranks of the pioneers who defied social convention and the longest odds to become database poets, information-wranglers, hypertext dreamers, and glass ceiling-shattering dot com-era entrepreneurs.

    But all too often, even the most respected publications present numbers that are miscalculated, misinterpreted, hyped, or simply misleading. Following on the heels of his highly acclaimed Damned Lies and Statistics and More Damned Lies and Statistics, Joel Best now offers this practical field guide to help everyone identify questionable statistics. Entertaining, informative, and concise, Stat-Spotting is essential reading for people who want to be more savvy and critical consumers of news and information.Stat-Spotting features:* Pertinent examples from today's news, including the number of deaths reported in Iraq, the threat of secondhand smoke, the increase in the number of overweight Americans, and many more* A commonsense approach that doesn't require advanced math or statistics

    Economists Ivan and Tuvana Pastine explain why, in these situations, we sometimes cooperate, sometimes clash, and sometimes act in a way that seems completely random.Stylishly brought to life by award-winning cartoonist Tom Humberstone, Game Theory will help readers understand behaviour in everything from our social lives to business, global politics to evolutionary biology. It provides a thrilling new perspective on the world we live in.

    It’s time we stand face-to-digital-face with the true powers and limitations of the algorithms that already automate important decisions in healthcare, transportation, crime, and commerce. Hello World is indispensable preparation for the moral quandaries of a world run by code, and with the unfailingly entertaining Hannah Fry as our guide, we’ll be discussing these issues long after the last page is turned.

    The trial itself was sensational enough to attract the attention of the world’s largest association of professional forensic investigators. At the start, everyone expected a ‘guilty’ verdict. His fingerprints were at the scene, the murder weapon was in his car and a blood stain in the bathroom was matched to one of his shoes. And yet, he was acquitted and is now suing the Minister of Police, saying that the evidence was fabricated. Altbeker witnessed the trial, and looks closely at how the justice system failed both van der Vyver and Lotz.

    They reveal why general anesthesia is as dangerous as a parachute jump, giving birth in the US is nearly twice as risky as in the UK, and that the radiation from eating a banana shaves 3 seconds off your life. An entertaining guide to the statistics of personal risk, The Norm Chronicles will enlighten anyone who has ever worried about the dangers we encounter in our daily lives.

    It introduces first year Ph.D. students to standard graduate econometrics material from a modern perspective. It covers all the standard material necessary for understanding the principal techniques of econometrics from ordinary least squares through cointegration. The book is also distinctive in developing both time-series and cross-section analysis fully, giving the reader a unified framework for understanding and integrating results.Econometrics has many useful features and covers all the important topics in econometrics in a succinct manner. All the estimation techniques that could possibly be taught in a first-year graduate course, except maximum likelihood, are treated as special cases of GMM (generalized methods of moments). Maximum likelihood estimators for a variety of models (such as probit and tobit) are collected in a separate chapter. This arrangement enables students to learn various estimation techniques in an efficient manner. Eight of the ten chapters include a serious empirical application drawn from labor economics, industrial organization, domestic and international finance, and macroeconomics. These empirical exercises at the end of each chapter provide students a hands-on experience applying the techniques covered in the chapter. The exposition is rigorous yet accessible to students who have a working knowledge of very basic linear algebra and probability theory. All the results are stated as propositions, so that students can see the points of the discussion and also the conditions under which those results hold. Most propositions are proved in the text.For those who intend to write a thesis on applied topics, the empirical applications of the book are a good way to learn how to conduct empirical research. For the theoretically inclined, the no-compromise treatment of the basic techniques is a good preparation for more advanced theory courses.

    It also incorporates new information regarding the solar system and an account of complexity theory. This witty, lucid and engaging book makes the complex mathematics of chaos accessible and entertaining. Presents complex mathematics in an accessible style. Includes three new chapters on prediction in chaotic systems, control of chaotic systems, and on the concept of chaos. Provides a discussion of complexity theory.

    Increasingly, the decisions that affect our lives--where we go to school, whether we can get a job or a loan, how much we pay for health insurance--are being made not by humans, but by machines. In theory, this should lead to greater fairness: Everyone is judged according to the same rules.But as mathematician and data scientist Cathy O'Neil reveals, the mathematical models being used today are unregulated and uncontestable, even when they're wrong. Most troubling, they reinforce discrimination--propping up the lucky, punishing the downtrodden, and undermining our democracy in the process.

    That’s a mistake, Tim Harford says in The Data Detective. We shouldn’t be suspicious of statistics—we need to understand what they mean and how they can improve our lives: they are, at heart, human behavior seen through the prism of numbers and are often “the only way of grasping much of what is going on around us.” If we can toss aside our fears and learn to approach them clearly—understanding how our own preconceptions lead us astray—statistics can point to ways we can live better and work smarter.As “perhaps the best popular economics writer in the world” (New Statesman), Tim Harford is an expert at taking complicated ideas and untangling them for millions of readers. In The Data Detective, he uses new research in science and psychology to set out ten strategies for using statistics to erase our biases and replace them with new ideas that use virtues like patience, curiosity, and good sense to better understand ourselves and the world. As a result, The Data Detective is a big-idea book about statistics and human behavior that is fresh, unexpected, and insightful.
