A beautifully written insight into the stresses, strains and successes of working for the London Ambulance service.Is there anyone who hasn't wondered about the state of the occupant of an ambulance, screaming along with its sirens on and blue lights flashing? Have you? And have you wondered about the other people inside the ambulance, maybe fighting to save the patient's life? Or have you considered that the ambulance may be another 'maternataxi' ordered by a woman who can't be bothered to book a real cab and who then complains she can't smoke on the way to hospital? And that the medical technician inside might just be desperate to get back home from a busy shift, to have a cup of tea and catch up with his blog?Meet Tom Reynolds. Tom is an Emergency Medical Technician who works for the London Ambulance Service in East London. He has kept a blog of his daily working life since 2003 and his award-winning writing is, by turn, moving, cynical, funny, heart-rending and compassionate. It is never less than compelling.From the tragic to the hilarious, from the heartwarming to the terrifying, the stories Tom tells give a fascinating – and at times alarming – picture of life in inner-city Britain, and the people who are paid to mop up after it.

This is the last untold story of Bletchley Park. Using declassified information, Paul Gannon gives us a gripping account of the invention of the world's first true computer, Colossus.Uncover the secrets of Bletchley Park's code-breaking computers.In 1940, almost a year after the outbreak of the Second World war, Allied radio operators at an interception station in South London began picking up messages in a strange new code. Using science, maths, innovation and improvisation Bletchley Park codebreakers worked furiously to invent a machine to decipher what turned out to be the secrets of Nazi high command. It was called Colossus.What these codebreakers didn't realize was that they had to fashion the world's first true computer. When the war ended, this incredible invention was dismantled and hidden away for almost 50 years. Paul Gannon has pieced together the tremendous story of what is now recognized as the greatest secret of Bletchley Park.'Gannon's book contains a mass of utterly fascinating and largely unknown material about an immensely important wartime project, and is very welcome indeed.' - Brian Rendell, TES Read more

As the digital economy changes the rules of the game for enterprises, the role of software and IT architects is also transforming.

Software development today is embracing events and streaming data, which optimizes not only how technology interacts but also how businesses integrate with one another to meet customer needs. This phenomenon, called flow, consists of patterns and standards that determine which activity and related data is communicated between parties over the internet.This book explores critical implications of that evolution: What happens when events and data streams help you discover new activity sources to enhance existing businesses or drive new markets? What technologies and architectural patterns can position your company for opportunities enabled by flow? James Urquhart, global field CTO at VMware, guides enterprise architects, software developers, and product managers through the process.Learn the benefits of flow dynamics when businesses, governments, and other institutions integrate via events and data streamsUnderstand the value chain for flow integration through Wardley mapping visualization and promise theory modelingWalk through basic concepts behind today's event-driven systems marketplaceLearn how today's integration patterns will influence the real-time events flow in the futureExplore why companies should architect and build software today to take advantage of flow in coming years Read more

Tidying up messy software is a must. And that means breaking up the code to make it more readable, and using guard clauses and helping functions to make it understandable. In this practical guide, author Kent Beck, creator of Extreme Programming and pioneer of software patterns, suggests when and where you might apply tidyings in your code.Instead of trying to master tidying all at once, this book lets you try out a few examples that make sense for your problem. If you have a big function containing many lines of code, you'll learn how to logically divide it into smaller chunks. Along the way, you'll learn the theory behind software design: coupling, cohesion, discounted cash flows, and optionality. Read more

As Python continues to grow in popularity, projects are becoming larger and more complex. Many Python developers are taking an interest in high-level software design patterns such as hexagonal/clean architecture, event-driven architecture, and the strategic patterns prescribed by domain-driven design (DDD). But translating those patterns into Python isn’t always straightforward.With this hands-on guide, Harry Percival and Bob Gregory from MADE.com introduce proven architectural design patterns to help Python developers manage application complexity—and get the most value out of their test suites. Each pattern is illustrated with concrete examples in beautiful, idiomatic Python, avoiding some of the verbosity of Java and C# syntax. Patterns include:Dependency inversion and its links to ports and adapters (hexagonal/clean architecture)Domain-driven design’s distinction between Entities, Value Objects, and Aggregates Repository and Unit of Work patterns for persistent storageEvents, commands, and the message busCommand-query responsibility segregation (CQRS)Event-driven architecture and reactive microservices Read more

The practice of enterprise application development has benefited from the emergence of many new enabling technologies. Multi-tiered object-oriented platforms, such as Java and .NET, have become commonplace. These new tools and technologies are capable of building powerful applications, but they are not easily implemented. Common failures in enterprise applications often occur because their developers do not understand the architectural lessons that experienced object developers have learned. Patterns of Enterprise Application Architecture is written in direct response to the stiff challenges that face enterprise application developers. The author, noted object-oriented designer Martin Fowler, noticed that despite changes in technology--from Smalltalk to CORBA to Java to .NET--the same basic design ideas can be adapted and applied to solve common problems. With the help of an expert group of contributors, Martin distills over forty recurring solutions into patterns. The result is an indispensable handbook of solutions that are applicable to any enterprise application platform.  This book is actually two books in one. The first section is a short tutorial on developing enterprise applications, which you can read from start to finish to understand the scope of the book's lessons. The next section, the bulk of the book, is a detailed reference to the patterns themselves. Each pattern provides usage and implementation information, as well as detailed code examples in Java or C#. The entire book is also richly illustrated with UML diagrams to further explain the concepts. Armed with this book, you will have the knowledge necessary to make important architectural decisions about building an enterprise application and the proven patterns for use when building them.  The topics covered include ·  Dividing an enterprise application into layers ·  The major approaches to organizing business logic ·  An in-depth treatment of mapping between objects and relational databases ·  Using Model-View-Controller to organize a Web presentation ·  Handling concurrency for data that spans multiple transactions ·  Designing distributed object interfaces Read more
