Any programmer working with a dynamically typed language will tell you how hard it is to scale to more lines of code and more engineers. Thats why Facebook, Google, and Microsoft invented gradual static type layers for their dynamically typed JavaScript and Python code. This practical book shows you how one such type layer, TypeScript, is unique among them: it makes programming fun with its powerful static type system.If youre a programmer with intermediate JavaScript experience, author Boris Cherny will teach you how to master the TypeScript language. Youll understand how TypeScript can help you eliminate bugs in your code and enable you to scale your code across more engineers than you could before.In this book, youll:Start with the basics: Learn about TypeScripts different types and type operators, including what theyre for and how theyre usedExplore advanced topics: Understand TypeScripts sophisticated type system, including how to safely handle errors and build asynchronous programsDive in hands-on: Use TypeScript with your favorite frontend and backend frameworks, migrate your existing JavaScript project to TypeScript, and run your TypeScript application in production

A textbook for students with limited background in mathematics and computer coding, emphasizing computer tutorials that guide readers in producing models of neural behavior.This introductory text teaches students to understand, simulate, and analyze the complex behaviors of individual neurons and brain circuits. It is built around computer tutorials that guide students in producing models of neural behavior, with the associated Matlab code freely available online. From these models students learn how individual neurons function and how, when connected, neurons cooperate in a circuit. The book demonstrates through simulated models how oscillations, multistability, post-stimulus rebounds, and chaos can arise within either single neurons or circuits, and it explores their roles in the brain. The book first presents essential background in neuroscience, physics, mathematics, and Matlab, with explanations illustrated by many example problems. Subsequent chapters cover the neuron and spike production; single spike trains and the underlying cognitive processes; conductance-based models; the simulation of synaptic connections; firing-rate models of large-scale circuit operation; dynamical systems and their components; synaptic plasticity; and techniques for analysis of neuron population datasets, including principal components analysis, hidden Markov modeling, and Bayesian decoding. Accessible to undergraduates in life sciences with limited background in mathematics and computer coding, the book can be used in a "flipped” or "inverted” teaching approach, with class time devoted to hands-on work on the computer tutorials. It can also be a resource for graduate students in the life sciences who wish to gain computing skills and a deeper knowledge of neural function and neural circuits.

Harden the human firewall against the most current threatsSocial Engineering: The Science of Human Hacking reveals the craftier side of the hacker's repertoire--why hack into something when you could just ask for access? Undetectable by firewalls and antivirus software, social engineering relies on human fault to gain access to sensitive spaces; in this book, renowned expert Christopher Hadnagy explains the most commonly-used techniques that fool even the most robust security personnel, and shows you how these techniques have been used in the past. The way that we make decisions as humans affects everything from our emotions to our security. Hackers, since the beginning of time, have figured out ways to exploit that decision making process and get you to take an action not in your best interest. This new Second Edition has been updated with the most current methods used by sharing stories, examples, and scientific study behind how those decisions are exploited.Networks and systems can be hacked, but they can also be protected; when the "system" in question is a human being, there is no software to fall back on, no hardware upgrade, no code that can lock information down indefinitely. Human nature and emotion is the secret weapon of the malicious social engineering, and this book shows you how to recognize, predict, and prevent this type of manipulation by taking you inside the social engineer's bag of tricks.* Examine the most common social engineering tricks used to gain access* Discover which popular techniques generally don't work in the real world* Examine how our understanding of the science behind emotions and decisions can be used by social engineers* Learn how social engineering factors into some of the biggest recent headlines* Learn how to use these skills as a professional social engineer and secure your company* Adopt effective counter-measures to keep hackers at bayBy working from the social engineer's playbook, you gain the advantage of foresight that can help you protect yourself and others from even their best efforts. Social Engineering gives you the inside information you need to mount an unshakeable defense.

To Save Everything, Click Here, the new book by the acclaimed author of The Net Delusion, Evgeny Morozov, is a penetrating look at the shape of society in the digital age, of the direction in which the 21st Century may take us, and of the alternate paths we can still chooseOur society is at a crossroads. Smart technology is transforming our world, making many aspects of our lives more convenient, efficient and - in some cases - fun. Better and cheaper sensors can now be embedded in almost everything, and technologies can log the products we buy and the way we use them. But, argues Evgeny Morozov, technology is having a more profound effect on us: it is changing the way we understand human society.In the very near future, technological systems will allow us to make large-scale and sophisticated interventions into many more areas of public life. These are the discourses by which we have always defined our civilisation: politics, culture, public debate, morality, humanism. But how will these discourses be affected when we delegate much of the responsibility for them to technology? The temptation of the digital age is to fix everything - from crime to corruption to pollution to obesity - by digitally quantifying, tracking, or gamifiying behaviour. Yet when we change the motivations for our moral, ethical and civic behaviour, do we also change the very nature of that behaviour? Technology, Morozov proposes, can be a force for improvement - but only if we abandon the idea that it is necessarily revolutionary and instead genuinely interrogate why and how we are using it.From urging us to drop outdated ideas of the internet to showing how to design more humane and democratic technological solutions, To Save Everything, Click Here is about why we should always question the way we use technology.'A devastating expos of cyber-utopianism by the world's most far-seeing Internet guru' John Gray, author of Straw Dogs'Evgeny Morozov is the most challenging - and best-informed - critic of the Techno-Utopianism surrounding the Internet.
