  • System programming (or systems programming) is the activity of programming system software. The primary distinguishing characteristic of systems programming when compared to application programming is that application programming aims to produce software which provides services to the user (e.g. word processor), whereas systems programming aims to produce software which provides services to the computer hardware (e.g. disk defragmenter). It requires a greater degree of hardware awareness.

  • The importance of mobile systems programming has emerged over the recent years as a new domain in software development. The design of software that runs in a mobile device requires that developers combine the rules applicable in embedded environment; memory-awareness, limited performance, security, and limited resources with features that are needed in workstation environment; modifiability, run-time extensions, and rapid application development. Programming Mobile Devices is a comprehensive, practical introduction to programming mobile systems.

  • KIPS is an automatic programming system which generates standardized business application programs through interactive natural language dialogue. KIPS models the program under discussion and the content of the user's statements as organizations of dynamic objects in the object*oriented programming sense. This paper describes the statement*model and the program-model, their use in understanding Japanese program specifications, and bow they are shaped by the linguistic singularities of Japanese input sentences. ...

  • This lecture provides a brief overview of what distinguishes embedded systems programming from “ordinary programming.” It then touches upon facilities that become prominent or problems when working “close to the hardware” such as free store use, bit manipulation, and coding standards. Remember: not all computers are little grey boxes hiding under desks in offices.

  • Linux is a Unix-like computer operating system assembled under the model of free and open source software development and distribution.Linux was originally developed as a free operating system for Intel x86-based personal computers. It has since been ported to more computer hardware platforms than any other operating system. Most Linux distributions support dozens of programming languages.

  • Using a series of web development examples, this book 'C Programming in Linux' will give you an interesting glimpse into a powerful lower-level world. C is tight and spare and economical, and in the current world climate people who know C will ensure critical systems keep running. A knowledge of C is now and has been for years a pre-requisite for serious software professionals and with the recent popularity and maturity of Open Systems this is even more true.

  • Dennis Ritchie at AT&T Bell Laboratories pioneered the C programming language in the early 1970s. However, this programming language did not begin to gain widespread popularity and support until the late 1970s.This was because, until that time, C compilers were not readily available for commercial use outside of Bell Laboratories. Initially, this growth in popularity was also partly spurred by the equal, if not faster, growth in popularity of the UNIX operating system, which was written almost entirely in C. Brad J. Cox designed the Objective-C language in the early 1980s.

  • Scala is an exciting, modern, multi-paradigm language for the JVM. You can use it to write traditional, imperative, object-oriented code. But you can also leverage its higher level of abstraction to take full advantage of modern, multicore systems. Programming Scala will show you how to use this powerful functional programming language to create highly scalable, highly concurrent applications on the Java Platform.

  • The purpose of this book is to teach solid idiomatic Go programming using all the features the language provides, as well as the most commonly used Go packages from Go’s standard library. The book is also designed to serve as a useful reference once the language is learned. To meet both of these goals the book is quite comprehensive and tries to cover every topic in just one place—and with forward and backward cross-references throughout. Go is quite C-like in spirit, being a small and efficient language with convenient low-level facilities such as pointers.

  • During the evolution of jBPM, leading up to Activiti, I took a new approach to the old problem. Initially, the focus was on state machines, but eventually we constructed an engine to match the way business people and developers collaborate. We designed the engine in such a way that it would allow business people to define the graphical flow of the process and, at the same time, give developers the opportunity to bind program logic inside the process flows. In addition, the engine was lightweight and integrated easily into any Java environment. The result was what we call embeddable BPM....

  • The developers chose the 8088 over the 8086 because, while the 8088 worked on a 16-bit basis internally, it only communicated with the outside world using an 8-bit data bus. Since the 8-bit DataMaster data bus already existed, the 8088 was the obvious choice. This bus connects the motherboard of the PC, where the processor and its support chips are resident, to the memory and the expansion boards, which are plugged into the expansion slots.
