## Algorithms

This course aims to be an accessible introduction to the design and analysis of efficient algorithms. Throughout the course we will introduce only the most basic techniques and describe the rigorous mathematical methods needed to analyze them. The topics covered include: The goal of the course is to show you how you can methodically apply different techniques to your own algorithms to make them more efficient. While This course mostly highlights general techniques, some well-known algorithms are also looked at in depth. This course is written so it can be read from "cover to cover" in the length of a semester, where sections marked with a * may be skipped. This course is a tutorial on techniques and is not a reference. For references we highly recommend the tomes by [Knuth] and [CLRS]. Additionally, sometimes the best insights come from the primary sources themselves (e.g. [Hoare]). A wikibook is an undertaking similar to an open-source software project: A contributor creates content for the project to help others, for personal enrichment, or to accomplish something for the contributor's own work (e.g., lecture preparation).

## Knowing Knoppix

Knowing Knoppix is a guide to the Knoppix Linux distro for the complete beginner. Knoppix is an astoundingly clever product. It runs Linux completely from a CD, DVD or USB drive. There is no need to install. It bypasses all the software already installed on your PC or laptop and automatically detects the hardware in your computer (subject to suitable hardware). When you've finished using Knoppix, simply restart. Your computer will return to your regular system, and it will behave as if nothing has happened. Knoppix is Free Software and open source under the terms of the GNU General Public Licence (GPL). This beginner-friendly book is designed to help with these situations: To run Knoppix in full and follow the instructions in Knowing Knoppix, you need:

## Algorithm Implementation

The purpose of This course is to show how common algorithms are written in various programming languages, providing code implementations and explanation. The plan for This course is initially to collect code from some Wikipedia articles. Then the code can be expanded upon, perfected, and heavily commented to provide insight into how it works.

## Data Structures

This course is about the creation and analysis of efficient data structures. It covers: To understand the material in This course you should be comfortable enough in a programming language to be capable of working with and writing your own variables, arithmetic expressions, if-else conditions, loops, subroutines (also known as functions), pointers (also known as references or object handles), structures (also known as records or classes), simple input and output, and simple recursion. Because many different languages approach the construction of data structures differently, we use pseudo-code so that you can translate the code into your own language. A Wikibook is an undertaking similar to an open-source software project: A contributor creates content for the project to help others, for personal enrichment, or to accomplish something for the contributor's own work (e.g., lecture preparation). An open book, just like an open program, requires time to complete, but it can benefit greatly from even modest contributions from readers. For example you can fix "bugs" in the text (where the bug might be typographic, expository, technical, aesthetic or otherwise) in order to make a better book. If you find an opportunity to fix a bug, simply click on "edit", make your changes, and click on save. Other contributors may review your changes to be sure they are appropriate for the course. If you are unsure, you can visit the discussion page and ask there. Use common sense.

## Embedded Systems

This course is about microcontrollers, in the field of digital control systems. We will discuss embedded systems, real-time operating systems, and other topics of interest. It is important to realize that embedded systems rarely have display capabilities, and if they do have displays, they are usually limited to small text-only LCD displays. The challenge of programming an embedded system then is that it is difficult to get real-time feedback from the system without a display. It is common to use a simple serial interface for diagnostic purposes, for example by connecting to a PC running terminal software via a RS-232 to USB adapter. Also, embedded systems usually have very strict memory limitations, processor limitations, and speed limitations that must play a factor in designing an embedded system, and programming an embedded computer. This course talks about some of the specific issues involved in programming an embedded computer. It also covers some basic topics such as microprocessor architectures, FPGAs, and some general low-level computing topics. While many of the issues discussed in This course may apply to PCs, and non-embedded computers, This course remains focused on topics that apply to embedded systems only. This course has incorporated a number of smaller books, stub-books, and half-books that were previously written about this subject.

## A Level Computer Science Programming Guide

This course is essentially a quick and easy lookup guide to easily study the components of the different programming languages required in the AS and A Level Computer Science course. It is not designed to teach you how to program, but rather to help you to remember and easily translate your code to the different languages. All Pseudocode in this guide is based on various Cambridge Mark Schemes and Help Guides, so it is as accurate as possible. When complete, the High-Level languages covered in this guide will be those that are set in the Cambridge syllabus; VB.Net, Python and Pascal/Delphi.

## Chip Design Made Easy

In This course Chip Design we tell how to build an integrated circuit ("chip") by integrating billions of transistors to achieve an application. An application could be suiting a particular requirement like microprocessor, router, cell phone,etc. An integrated circuit designed for a specific application is called as ASIC (Application Specific Integrated Circuits). Today's ASIC Chips are pretty complex, packed with larger chunk of transistors targeted to a specific manufacturing process for fabricating the integrated circuits, in a sub nanometer regime, involving many challenges like knowledge of various protocols, architectures, models, formats, standards, knowledge about CMOS logic, Digital Design concepts, taming the EDA tool for the various design requirements like area, timing, power, thermal, noise, routability, lithography aware, knowledge about various variabilities like channel length, Vt, line width variations, lens aberrations, IR drop effects, inter-die and intra die-variations, effects, and various noise-effects like package noise, EMI noise, power grid noise, cross-talk noise, and ability to test and validate and know to model and characterize all these effects upfront in the design-phase, steps to increase profitability curve, with short span of time-to market to minimize the risk and maximize the predictability and an modular approach to success. Now let's delve in to the "Art of Chip Designing". That is a lot of technical jargon, but there is nothing to worry about. You will soon learn what that means, and understand the concepts behind chip designing. Why an Analogy with Building Architecture? To understand the concepts of Chip designing in a better way, as we are very familiar with Building Architecture, then it will be easy for us to map Chip Design architecture.

## Evolution of Operating Systems Designs

This course is about operating systems concepts as they have evolved through the history of operating systems implementations. Politics and implementation details are irrelevant. Emphasis is given to technically successful designs, aesthetic operating systems, and not on commercial success. In fact, mere commercial success isn't sufficient to make an operating system noteworthy. It also emphasizes working implementations over mere projects.

## Finite Model Theory

Finite Model Theory (FMT) is a subarea of Model Theory (MT). MT is the branch of mathematical logic which deals with the relation between a formal language (syntax) and its interpretations (semantics). FMT is a restriction of MT to finite structures, such as finite graphs or strings. Since many central theorems of MT do not hold when restricted to finite structures, FMT is quite different from MT in methods and application areas. FMT has become an "unusually effective" instrument in computer science, for example in database theory, model checking or for gaining new perspectives on computational complexity. The three main areas of FMT are presented here: Expressive Power of Languages, Descriptive Complexity, and Random Structures. But first the results fundamental for all areas are introduced on the level of first order languages. Why? (Motivation) What is it? (Definition and Background)

## GNewSense

gNewSense is a free GNU/Linux operating system. In this case, free refers to freedom like free speech rather than free beer, which means you're allowed to do the following with gNewSense: gNewSense is great as it offers you the four freedoms as stated above. Well you can use Windows or OS X for any purpose you want. People who protect us, like police and army, use them; terrorists use Windows and OS X, too. The good news is that gNewSense can be used for anything, to create, to protect and to destroy. So gNewSense is leveled with competitive operating systems. Now let's talk about the second point of free software: to distribute it freely to your friends, and possibly enemies to get their good will, to family and loved ones. With gNewSense you can distribute the operating system because it's free(dom). If you distribute Windows or OS X, you will still be happy if you like to count bars behind prison. You will be called a pirate, criminal and possibly enemy of the state. If the above paragraph shocked you, then we must remind you that we are not kidding. It could happen to you if you use Windows or OS X. So you'd better start using gNewSense or risk facing the cold shoulder of society. In court you could argue that you had purchased Microsoft Windows or Mac OS X for yourself and that you have the right to do anything you want with what you own. Well the bad news is even if you have purchased a copy of a proprietary Operating System, you do not own it.

## Discover Release Management

Release Management refers to management of the release cycle within a software project, which itself is when the software engineers provide a uniquely identified set of files for others to use. The others may be their department at work, their classmates at university, or The World. The set of files (perhaps a single file) constitute the software release. Managing the release means the software release manager knows: Building software is the generic term applied to the compilation or aggregation of sources into a usable utility or application. Sources needn't be compiled (built) in the classic sense, which relies upon a compiler linking files together; modern systems may consist entirely of interpreted source files (such as those for Perl or PHP). Still, putting everything together in a usable format may be considered "building". The larger and more complex the software project becomes, the greater the need for an extremely well-managed Build and Release function. Several features are characteristic of the Build and Release process. The most common are use of overnight builds, normalized build numbering, high degrees of automation, scheduling and reuse, use of notification, metadata capture and storage, and implementation of a project portal or viewer.

• Overnight builds
• Competent Build Numbering

## Windows: An Overview

At the time of this era, the Microsoft Windows family of operating systems runs the vast majority of the world's home computers. How did Windows rapidly become the dominant operating system for home use on the planet? Microsoft Windows began as a GUI add-on to DOS. The early versions of Windows required DOS to be installed first. The first version that did not require DOS to be pre-installed was Windows 95. Early on, Windows split into two branches - the DOS-based branch and the NT based branch. Today, The DOS-based branch has been discontinued due to bugs (errors in software), Lack of hardware support, and instability. All versions of Windows since Windows NT 3.1 (these are Windows NT 3.1, NT 4.0, Windows 2000, XP, Vista, 7, and 8) are NT based. Here are the predecessors to Microsoft Windows 95 in the order of release: Windows 1.0 Windows 2.0

## Mathematical Proof and the Principles of Mathematics

This course aims to teach you the elements of pure mathematics in a self-contained, accessible style. The main objective is to introduce the reader to material usually found in an undergraduate course intended for mathematics majors at a university. In fact, many universities offer a course that serves as a transition from calculus to courses which involve more abstract concepts and writing proofs, and This course might serve as a text for such a course. It's also intended for people who are considering mathematics, especially pure mathematics, as a career or serious avocation, and wish to know what to expect as they advance to higher levels. We also intend to introduce the reader to style of proofs and rigor needed to read and write mathematical literature. The material is covered in greater detail and more rigorously than you may be used to. In fact much of the material will already be familiar, though the approach to it may not. In the experience of most people, mathematics consists mostly of the mechanical application of rules of computation at various levels: arithmetic, solving equations, finding derivatives and integrals. But for a mathematician, mathematics is a process for discovering and establishing truths. It requires an analytical mind, but also a certain amount of creativity and intuition. It can also be, as we hope you'll discover Through this course, very rewarding. Introduction →

## Operating Systems

An operating system is software that manages and organises that computer's resources and basic functions, including: Operating system Unix was developed by a group of employees from Bell Labs under the guidance of Dennis Ritchie, Ken Thompson and Brian Kernighan in 1969. This operating system was created under the fundamentals of simplicity as they had few people working on the project and wanted to complete it relatively quickly. The design standards set by Unix paved the way for the modern computing world (except Windows). At the end of 1970's, the University of California, Berkeley made a number of improvements to the source code of UNIX, including the work with protocols of TCP/IP. Their work was known as BSD (Berkeley Software Distribution). It spread under licence, allowing to refine and improve the product and transfer the result to third parties, with or without source codes, provided that authorship of the code written in Berkeley is indicated. While there was some legal trouble, the case was ruled in favor of the Regents of California and that set a precedent that Unix-like operating systems are not under copyright so long as they contain no original Unix source code. Thus the BSD project had to remove all Unix based code from 4.4 BSD terming their new creation 4.4BSD lite. This BSD was limited in features so projects like FreeBSD and NetBSD sprung up to fill in the gaps. In the beginning of the 1990s, a student from Helsinki University Linus Torvalds started kernel development for IBM computers, that was known as w:Linux\Linux. Currently, GNU/Linux (a set of different distributions built on the basis of the Linux kernel) ranks second in popularity among OSs used on user desktops (first place belongs Microsoft Windows)

## Windows Batch Scripting

This course describes and shows how to use the Microsoft-supplied command interpreter cmd.exe and the associated commands, and how to write Windows batch scripts for the interpreter. cmd.exe is the default interpreter on all Windows NT-based operating systems, including Windows XP, Windows 7 and Windows 10. This course addresses 32-bit Windows commands applicable to modern versions of Windows based on the Windows NT environment. It does not address commands that are specific to DOS environments and to DOS-based operating systems, such as Windows 95, Windows 98, and Windows Me, whose Microsoft-supplied command interpreters are in fact DOS programs, not Win32 programs. You can find out which version of Windows you are running using the VER command. This course first describes using the Windows NT command interpreter, how it receives, parses, and processes commands from users. Then it describes various commands available. To obtain an extensive list of Windows commands and their short summaries, open the command prompt on any Windows computer, and type help. To find out about a particular command, type the name of the command followed by "/?".
