Developer platforms promise to rewrite the laws of IT physics: they boost innovation through standards; they speed up development while assuring compliance; and they reduce cognitive load without restricting choice. Building such an in-house platform, or even deploying one, is far from easy, though. This book condenses a decade of building and rolling out platforms into practical advice for platform teams and users.5300+ happy readers! Also as Paperback edition

A practical handbook packed with real-world advice to help you write better code, adopt effective developer habits, and build great software.

Now we have made it to the kernel. Let's assume you have a chip, any chip, from the suppliers we've just discussed. You might choose to manually load a kernel onto that chip, using a GRand Unified Bootloader (GRUB) to load (or strap) the kernel, and pass all permissions over to it. It is the animus in the machine. There are many different kernels, but they share one interesting characteristic to security: they run with the highest level of access, mediating interactions between user applications and the physical chips. A good kernel will handle low-level tasks like CPU scheduling, memory allocation, device input/output, and system calls. It is the bridge between software and hardware: if the kernel fails to load or crashes, the entire system will halt. To make this level of access a bit safer, the kernel is designed to be always resident in memory, and execute in a protected mode that is isolated from applications. This prevents damage to core system data...

The demand for skilled data science practitioners in industry, academia, and government is rapidly growing. This book introduces concepts from probability, statistical inference, linear regression and machine learning and R programming skills. Throughout the book we demonstrate how these can help you tackle real-world data analysis challenges.

When we learn, our brain builds models (mental models). These models form the foundation of our understanding, our intuition (whether right or wrong) and our habits. The better we understand this model building process, the better we can learn, solve problems, deal with change and create desired change while at the same time improving ourselves.

A complete foundation for Statistics, also serving as a foundation for Data Science.
