Hacking Secret Ciphers with Python not only teaches you how to write in secret ciphers with paper and pencil. This book teaches you how to write your own cipher programs and also the hacking programs that can break the encrypted messages from these ciphers. Unfortunately, the programs in this book won't get the reader in trouble with the law (or rather, fortunately) but it is a guide on the basics of both cryptography and the Python programming language. Instead of presenting a dull laundry list of concepts, this book provides the source code to several fun programming projects for adults and young adults.
If you’ve ever spent hours renaming files or updating hundreds of spreadsheet cells, you know how tedious tasks like these can be. But what if you could have your computer do them for you? In Automate the Boring Stuff with Python, you’ll learn how to use Python to write programs that do in minutes what would take you hours to do by hand—no prior programming experience required. Once you’ve mastered the basics of programming, you’ll create Python programs that effortlessly perform useful and impressive feats of automation to: –Search for text in a file or across multiple files –Create, update, move, and rename files and folders –Search the Web and download online content –Update and format data in Excel spreadsheets of any size –Split, merge, watermark, and encrypt PDFs –Send reminder emails and text notifications –Fill out online forms Step-by-step instructions walk you through each program, and practice projects at the end of each chapter challenge you to improve those programs and use your newfound skills to automate similar tasks. Don’t spend your time doing work a well-trained monkey could do. Even if you’ve never written a line of code, you can make your computer do the grunt work. Learn how in Automate the Boring Stuff with Python. Note: The programs in this book are written to run on Python 3.
Learn how to program in Python while making and breaking ciphers—algorithms used to create and send secret messages! After a crash course in Python programming basics, you’ll learn to make, test, and hack programs that encrypt text with classical ciphers like the transposition cipher and Vigenère cipher. You’ll begin with simple programs for the reverse and Caesar ciphers and then work your way up to public key cryptography, the type of encryption used to secure today’s online transactions, including digital signatures, email, and Bitcoin. Each program includes the full code and a line-by-line explanation of how things work. By the end of the book, you’ll have learned how to code in Python and you’ll have the clever programs to prove it! You’ll also learn how to: - Combine loops, variables, and flow control statements into real working programs - Use dictionary files to instantly detect whether decrypted messages are valid English or gibberish - Create test programs to make sure that your code encrypts and decrypts correctly - Code (and hack!) a working example of the affine cipher, which uses modular arithmetic to encrypt a message - Break ciphers with techniques such as brute-force and frequency analysis There’s no better way to learn to code than to play with real programs. Cracking Codes with Python makes the learning fun!

Publisher: HOEPLI EDITORE
Milan, since the period after World War II, has developed its own specific interpretation of modern architecture: a Milanese path to architectural Modernity. In model suburban developments like QT8 (a proving ground for the best solutions formulated by international architectural culture in the 1920s and 1930s), but also in original buildings in the center, like the Torre Velasca and the Pirelli skyscraper, Milan has become a true outdoor museum of modern architecture. The names of the leading figures of this period are Gio Ponti, Piero Bottoni, Ernesto Nathan Rogers, Lodovico Belgiojoso, Ignazio Gardella, Luigi Moretti, Luigi Caccia Dominioni, Vico Magistretti; as well as Vittorio Gregotti, Aldo Rossi, Guido Canella, Carlo Aymonino, Gino Valle, Gabetti & Isola: architects that over a few decades gave Milan its building-symbols, providing structures suitable for a city aspiring to a role as a leading player on the European stage. The works of these architects have been joined, in the late 20th century and the initial years of the new millennium, in a period of renewed construction activity, by projects bearing the world-famous signatures of Zaha Hadid, Daniel Libeskind, Arata Isozaki, Peter Eisenman and Rem Koolhaas, along with those of Italian talents like - among others - Renzo Piano, Cino Zucchi and Stefano Boeri. A significant contribution that has given Milan an important position on the international architecture scene, destined to be reinforced by EXPO 2015. This book takes a critical look at the various aspects of development of Milanese architecture, and in 100 profiles illustrated with photographs made for the occasion it presents the city's most outstanding buildings erected over the course of the last seventy years.
