Ada Lovelace was a most unlikely computer pioneer. In this film, Dr Hannah Fry tells the story of Ada's remarkable life. Born in the early 19th century Ada was a countess of the realm, a scandalous socialite and an 'enchantress of numbers'. The film is an enthralling tale of how a life infused with brilliance, but blighted by illness and gambling addiction, helped give rise to the modern era of computing.
Hannah traces Ada's unlikely union with the father of computers, Charles Babbage. Babbage designed the world's first steam-powered computers - most famously the analytical engine - but it was Ada who realised the full potential of these new machines. During her own lifetime Ada was most famous for being the daughter of romantic poet Lord Byron ('mad, bad and dangerous to know'). It was only with the advent of modern computing that Ada's understanding of their flexibility and power (that they could be far more than mere number crunchers) was recognised as truly visionary. Hannah explores how Ada's unique inheritance - poetic imagination and rational logic - made her the ideal prophet of the digital age.
This moving, intelligent and beautiful film makes you realise we nearly had a Victorian computer revolution.

Tired of reading HTML books that only make sense after you're an expert? Then it's about time you picked up Head First HTML and really learned HTML. 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 so they work in all browsers and mobile devices. 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, 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 and CSS into your brain in a way that sticks.
So what are you waiting for? Leave those other dusty books behind and come join us in Webville. Your tour is about to begin.

Master Python and become a programmer-even if you never thought you could! This breakthrough book and CD can help practically anyone get started in programming. It's called "The Hard Way," but it's really quite simple. What's "hard" is this: it requires discipline, practice, and persistence. Zed A. Shaw teaches the Python programming language through a series of 52 brilliantly-crafted exercises-all formatted consistently, and most no longer than two pages (including "extra credit"). Just read each exercise, type in its sample code precisely (no copy-and-paste!), and make the programs run. As you read, type, fix your mistakes, and watch the results, you'll learn how software works, how programming works, what good programs look like, and how to read, write, and see code. You'll discover how to spot crucial differences that fundamentally affect program behavior, and you'll learn everything you need to know about Python logic, input/output, variables, and functions. Above all, you'll learn the attention to detail that is indispensable to successful programming (and so much else in life). At first, yes, it can be difficult. But it gets easier. And Shaw offers plenty of extra guidance and insight through 5+ full hours of teaching video on the accompanying CD. As Shaw's thousands of online readers and fans will attest, the moment will come when you just "get it"-and that moment feels great. Nothing important comes without discipline, practice, and persistence. But, with Learn Python the Hard Way, readers who bring those qualities to programming will master it-and they will reap the rewards, both personally and in their careers.

This book introduces students with little or no prior programming experience to the art of computational problem solving using Python and various Python libraries, including PyLab. It provides students with skills that will enable them to make productive use of computational techniques, including some of the tools and techniques of "data science" for using computation to model and interpret data. The book is based on an MIT course (which became the most popular course offered through MIT's OpenCourseWare) and was developed for use not only in a conventional classroom but in in a massive open online course (or MOOC) offered by the pioneering MIT--Harvard collaboration edX. Students are introduced to Python and the basics of programming in the context of such computational concepts and techniques as exhaustive enumeration, bisection search, and efficient approximation algorithms. The book does not require knowledge of mathematics beyond high school algebra, but does assume that readers are comfortable with rigorous thinking and not intimidated by mathematical concepts. Although it covers such traditional topics as computational complexity and simple algorithms, the book focuses on a wide range of topics not found in most introductory texts, including information visualization, simulations to model randomness, computational techniques to understand data, and statistical techniques that inform (and misinform) as well as two related but relatively advanced topics: optimization problems and dynamic programming. Introduction to Computation and Programming Using Python can serve as a stepping-stone to more advanced computer science courses, or as a basic grounding in computational problem solving for students in other disciplines.

"The computer world is like an intellectual Wild West, in which you can shoot anyone you wish with your ideas, if you're willing to risk the consequences. " --from Hackers & Painters: Big Ideas from the Computer Age , by Paul Graham We are living in the computer age, in a world increasingly designed and engineered by computer programmers and software designers, by people who call themselves hackers. Who are these people, what motivates them, and why should you care? Consider these facts: Everything around us is turning into computers. Your typewriter is gone, replaced by a computer. Your phone has turned into a computer. So has your camera. Soon your TV will. Your car was not only designed on computers, but has more processing power in it than a room-sized mainframe did in 1970. Letters, encyclopedias, newspapers, and even your local store are being replaced by the Internet. Hackers & Painters: Big Ideas from the Computer Age , by Paul Graham, explains this world and the motivations of the people who occupy it. In clear, thoughtful prose that draws on illuminating historical examples, Graham takes readers on an unflinching exploration into what he calls "an intellectual Wild West." The ideas discussed in this book will have a powerful and lasting impact on how we think, how we work, how we develop technology, and how we live. Topics include the importance of beauty in software design, how to make wealth, heresy and free speech, the programming language renaissance, the open-source movement, digital design, internet startups, and more.

Structure and Interpretation of Computer Programs has had a dramatic impact on computer science curricula over the past decade. This long-awaited revision contains changes throughout the text.
There are new implementations of most of the major programming systems in the book, including the interpreters and compilers, and the authors have incorporated many small changes that reflect their experience teaching the course at MIT since the first edition was published.
A new theme has been introduced that emphasizes the central role played by different approaches to dealing with time in computational models: objects with state, concurrent programming, functional programming and lazy evaluation, and nondeterministic programming. There are new example sections on higher-order procedures in graphics and on applications of stream processing in numerical programming, and many new exercises.
In addition, all the programs have been reworked to run in any Scheme implementation that adheres to the IEEE standard.
