Lean Software Systems Engineering for Developers
Graduate to the next level of your software development career, learning the tools you need to successfully manage the complexity of modern software systems. Whether you are a developer at a small software company, or one of many developers at a large enterprise, your success directly correlates to the ability of your development team to rapidly respond to change. What makes this task challenging in today's world, is that the technical challenges we as developers strive to overcome are becoming increasingly more complex. We have to consider many more options when it comes to things like requirements, solution hosting, support, pace of change, and generally with less time and warning. A good developer knows that it is critical to manage every aspect of software development from soup to nuts, and understands that when details and decisions are left to chance, outcomes can be negatively impacted. Poor planning can result in increased errors, substandard quality, budget and schedule ...

Just Enough R
If your job involves working with data in any manner, you cannot afford to ignore the R revolution! If your domain is called data analysis, analytics, informatics, data science, reporting, business intelligence, data management, big data, or visualization, you just have to learn R as this programming language is a game-changing sledgehammer. However, if you have looked at a standard text on R or read some of the online discussions, you might feel that there is a steep learning curve of six months or more to grok the language. I will debunk this myth through my book by focusing on practical essentials instead of theory. If you have programmed in some language in the past (whether that language be SAS, SPSS, C, C++, C#, Java, Python, Perl, Visual Basic, Ruby, Scala, shell scripts, or plain old SQL), even if you are rusty, this book will get you up and running with R in a single day, writing programs for data analysis and visualization. ...

Multithreaded JavaScript
Traditionally, JavaScript has been a single-threaded language. Nearly all online forum posts, books, online documentation, and libraries refer to the language as single threaded. Thanks to recent advancements in the language-such as the Atomics and SharedArrayBuffers objects and Web Workers in the browser-JavaScript is now a multi-threaded language. These features will go down as being the biggest paradigm shift for the world's most popular programming language. Multithreaded JavaScript explores the various features that JavaScript runtimes have at their disposal for implementing multithreaded programming, providing both practical real-world examples, as well as reference material. Learn what multithreaded programming is and how you can benefit from it; Understand the differences between a web worker, a service worker, and a worker thread; Know when and when not to use threads in an application; Orchestrate communication between threads by leveraging the Atomics object; Build hig ...
