Peer-to-peer (P2P) networks are a type of computer network architecture where individuals form a loose group to share resources directly with others in the group without a centralized server. There are two main types of P2P network structures - unstructured and structured. Unstructured networks do not use algorithms to organize the network, while structured networks use algorithms to optimize routing. Popular applications of P2P networking include file sharing, media streaming, grid computing, instant messaging, and voice over internet protocol.

CHAPTER 1: Creating a Program
OBJECTIVES
· Analyze some of the issues involved in producing a simple program:
· Requirements (functional, nonfunctional)
· Design constraints and design decisions
· Testing
· Effort estimation
· Implementation details
· Understand the activities involved in writing even a simple program.
· Preview many additional software engineering topics found in the later chapters.
1.1 A Simple Problem
In this chapter we will analyze the tasks involved in writing a relatively simple program. This will serve as a contrast to what is involved in developing a large system, which is described in Chapter 2.
Assume that you have been given the following simple problem: “Given a collection of lines of text (strings) stored in a file, sort them in alphabetical order, and write them to another file.” This is probably one of the simplest problems you will be involved with. You have probably done similar assignments for some of your introduction to programming classes.
1.1.1 Decisions, Decisions
A problem statement such as the one mentioned in the above simple problem does not completely specify the problem. You need to clarify the requirements in order to produce a program that better satisfies the real problem. You need to understand all the program requirements and the design constraints imposed by the client on the design, and you need to make important technical decisions. A complete problem statement would include the requirements, which state and qualify what the program does, and the design constraints, which depict the ways in which you can design and implement it.
Program requirements Statements that define and qualify what the program needs to do.
Design constraints Statements that constrain the ways in which the software can be designed and implemented.
The most important thing to realize is that the word requirements is not used as it is in colloquial English. In many business transactions, a requirement is something that absolutely must happen. However, in software engineering many items are negotiable. Given that every requirement will have a cost, the clients may decide that they do not really need it after they understand the related cost. Requirements are often grouped into those that are “needed” and those that are “nice to have.”
It is also useful to distinguish between functional requirements—what the program does—and nonfunctional requirements—the manner in which the program must behave. In a way, a function is similar to that of a direct and indirect object in grammar. Thus the functional requirements for our problem will describe what it does: sort a file (with all the detail required); the nonfunctional requirements will describe items such as performance, usability, and maintainability. Functional requirements tend to have a Boolean measurement where the requirement is either satisfied or not satisfied, but nonfunctional requirements tend to apply to things measured on a linear scale where the measurements ca.

It discusses Test Driven Development (TDD), the differences between TDD and BDD, and the key features of BDD including using a common language that business and technical stakeholders can understand. The document then covers an introduction to Cucumber, its advantages over other tools, prerequisites for using Cucumber, and how a basic Cucumber framework is structured including feature files, step definitions, and a test runner file. It also discusses using backgrounds in Cucumber to define common starting context across scenarios.
Functional tests with the FEST frameworkDominik Dary
This document describes the FEST framework for automated functional GUI testing of Swing-rich applications. FEST provides a fluent interface and supports TestNG and JUnit. It simplifies troubleshooting GUI test failures and has good documentation. FEST is divided into modules for Swing, assertions, reflection, and mocking. The Swing module simulates user events and lookups GUI components using layers including a basic robot, component drivers, and component fixtures that provide a DSL-style API. Examples show how to enter text, select components, and assert results using FEST's fluent interface.
S-CUBE LP: Data Dependency: Inferring Data Attributes in Service Orchestratio...virtual-campus
This document provides an overview of an approach to automatically inferring data attributes in service orchestrations based on sharing analysis. The key steps include: (1) conceptualizing the input data context as a concept lattice, (2) translating the workflow definition into a Horn clause program, (3) performing sharing analysis on the program to derive an abstract substitution, and (4) interpreting the substitution to construct an output concept lattice and resulting context with inferred attributes. Background information is also provided on concept lattices, Horn clause programs, and related techniques like substitutions and unification that are used in the approach.
The document provides an introduction to the Autotools build system used for cross-platform compilation of software. It discusses the main Autotools tools - Autoconf, Automake and Libtool, and how they help make software portable across operating systems by addressing differences in platforms. The document gives an overview of how Autotools works from both a user and developer perspective, and provides resources for learning more about Autotools and related standards like the GNU Coding Standards.
OSGi Semantic Versioning with Baselining in enRoute - P Kriensmfrancis
OSGi Community Event 2014
Abstract:
Most people consider versions tedious and boring. And they are right! However, that does not make them less important. Unless you always compile all your code together and never have to go back in time, versions are the threads that keep the systems together in a stable way. That is, if people did not make those stupid mistakes with versions ...
Meet semantic versioning and baselining. Semantic versions provide a framework to automate version handling. This framework is used in bnd(tools) to automate most version handling.
This presentation will show what OSGi semantic versions are and its extension to also semantically version contracts. It will demonstrate the bnd(tools) support which is part of enRoute to detect semantic version violations in real time as well as in the continuous build.
Speaker Bio:
Peter Kriens is an independent consultant since 1990.He currently works for the OSGi Alliance and jpm4j. During the eighties he developed advanced distributed systems for newspapers based on microcomputers based on, at the time very novel, object oriented technologies. For this experience in Objects he was hired by a number of international companies, including Adobe, Intel, Ericsson, IBM, and many others. During his work at Ericsson Research in 1998 he got involved with the OSGi specification; Later he became the primary editor for these specifications. In 2005 he was awarded the OSGi Fellows title. After taking a sabbatical in 2012 to develop jpm4j he returned to the OSGi Alliance to help increasing adoption. He is Dutch but decided to live in France.

4. Overview
Welcome to the JNCIA-Junos Study Guide—Part 1. The purpose of this guide is to help you
prepare for your JN0-101 exam and achieve your JNCIA-Junos credential. The contents of this
document are based on the Introduction to Junos Software course. This study guide provides
students with the foundational knowledge required to work with the Junos operating system
and to configure Junos devices. The study guide provides a brief overview of the Junos device
families and discusses the key architectural components of the software. Additional key topics
include user interface options with a heavy focus on the command-line interface (CLI),
configuration tasks typically associated with the initial setup of devices, interface configuration
basics with configuration examples, secondary system configuration, and the basics of
operational monitoring and maintenance of Junos devices.

5. Document Conventions
CLI and GUI Text
Frequently throughout this study guide, we refer to text that appears in a command-line
interface (CLI) or a graphical user interface (GUI). To make the language of these documents
easier to read, we distinguish GUI and CLI text from chapter text according to the following
table.
Style Description Usage Example
Franklin Normal text. Most of what you read in the
Gothic Student Guide.
Courier Console text:
New commit complete
• Screen captures
• Noncommand-related Exiting configuration
syntax mode
GUI text elements: Select File > Open, and then
click Configuration.conf in
• Menu names
the Filename text box.
• Text field entry
Input Text Versus Output Text
You will also frequently see cases where you must enter input text yourself. Often this will be
shown in the context of where you must enter it. We use bold style to distinguish text that is
input versus text that is simply displayed.
Style Description Usage Example
Normal CLI No distinguishing variant. Physical interface:fxp0,
Enabled
Normal GUI
View configuration history by
clicking Configuration >
History.
CLI Input Text that you must enter. lab@San_Jose> show route
GUI Input Select File > Save, and enter
config.ini in the Filename
field.

6. Defined and Undefined Syntax Variables
Finally, this study guide distinguishes between regular text and syntax variables, and it also
distinguishes between syntax variables where the value is already assigned (defined variables)
and syntax variables where you must assign the value (undefined variables). Note that these
styles can be combined with the input style as well.
Style Description Usage Example
CLI Text where variable value is already policy my-peers
Variable assigned.
Click on my-peers in the dialog.
GUI
variable
CLI Text where the variable’s value is Type set policy
Undefined the user’s discretion and text where policy-name.
the variable’s value might differ
GUI ping 10.0.x.y
from the value the user must input.
Undefined
Select File > Save, and enter
filename in the Filename field.
