Learn how to manipulate functions and expressions to modify how the R language interprets itself. This book is an introduction to metaprogramming in the R language, so you will write programs to manipulate other programs. Metaprogramming in R shows you how to treat code as data that you can generate, analyze, or modify. R is a very high-level language where all operations are functions and all functions are data that can be manipulated. This book shows you how to leverage R´s natural flexibility in how function calls and expressions are evaluated, to create small domain-specific languages to extend R within the R language itself. What You´ll Learn Find out about the anatomy of a function in R Look inside a function call Work with R expressions and environments Manipulate expressions in R Use substitutions Who This Book Is For Those with at least some experience with R and certainly for those with experience in other programming languages.

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online.RAID is an acronym first defined by David A. Patterson, Garth A. Gibson, and Randy Katz at the University of California, Berkeley in 1987 to describe a redundant array of inexpensive disks, a technology that allowed computer users to achieve high levels of storage reliability from low-cost and less reliable PC-class disk-drive components, via the technique of arranging the devices into arrays for redundancy. Marketers representing industry RAID manufacturers later reinvented the term to describe a redundant array of independent disks as a means of dissociating a ´´low cost´´ expectation from RAID technology.

What You´ll Learn Low-Level Programming teaches programmers to: Freely write in assembly language Understand the programming model of Intel 64 Write maintainable and robust code in C11 Follow the compilation process and decipher assembly listings Debug errors in compiled assembly code Use appropriate models of computation to greatly reduce program complexity Write performance-critical code Comprehend the impact of a weak memory model in multi-threaded applications Who This Book Is For Intermediate to advanced programmers and programming students
Since the realization of speed and powerful cars, people are getting faster to reach their destinations such as working appointments, relatives visiting...etc, that moment of discovering changed the world totally and showed that the human´s brain can challenge the lif e´s difficulties and ameliorate the life´s style for better , that from the positive side from the opposite one the human´s brain showed also that humans be don´t like following rules and laws and most of catastrophes caused by t his mentality, the best example of that is the road phenomenon and basing on it a lot of people are losing their lives daily. Governments tried a lot finding solutions to this phenomenon but no success till now and the number of people killed is increasing daily, all statistics are focusing on the human facts which is not following the road safety instructions to avoid accidents and keeping people lives , 99% of researchers found that the main cause of this phenomenon is the high speed which is controlled by the car´s users and they found that drivers are always crossing the speed limit in each accident committed.
