JavaScript Tutorials and Workshops

JavaScript is a simple, relatively easy to use programming language for Web pages. It gives you a way to add interactivity to your Web pages. With JavaScript you can transform your Web pages from static displays to pages that react to and process information from those who view your pages. JavaScript does not require a lot of programming skill on your part to get started. You can pick up the basics of JavaScript in a short time.

Why Use JavaScript

  • JavaScript is an integral component of AJAX, the latest method to code web pages, allowing greater user interaction and better performance.
  • JavaScript offers a programming language for Web pages that most anyone can use.
  • JavaScript is becoming a standard for Web page programming. This means you're more assured that your work will not soon disappear. There are thousands of Web sites that use JavaScript today.
  • JavaScript makes your Web pages come alive by responding to things a user does on your pages.
  • JavaScript is ideal for form field validation. If it’s important that this data conform to a certain format, you can use JavaScript to validate the data on the user’s machine before it is forwarded to the server.
  • JavaScript can open and close new browser windows and you can control the appearance of the new windows you create. You can control their size, their location, and the toolbars they have available.
  • JavaScript can perform mathematical computations.
  • JavaScript can make your Web pages look “fresh” and up-to-date. For example, if your Web page displays the current date, it feels a little more up-to-date.
  • JavaScript is Fun. There are a lot of neat things you can do with JavaScript which provide immediate visual feedback.

The following JavaScript Tutorials and Workshops, from West Virginia University, will teach you more on how to code features into web pages using JavaScript. The JavaScript tutorials and workshops contain illustrated explanations and examples of the concepts being taught, followed by detailed learning activities.

Free Algorithms Book

This free book, named Algorithms, contains algorithm topics carefully selected and clustered. Instead of dwelling on formal proofs the authors distilled in each case the crisp mathematical idea that makes the algorithm work. In other words, they emphasized rigor over formalism.

There are four parts to this Algorithms books:

Part I of the book starts at the historical beginning: numbers, primality, and factoring, and also includes the RSA cryptosystem, and divide-and-conquer algorithms for integer multiplication, sorting and median finding, as well as the fast Fourier transform.

Part II, the most traditional section of the book, concentrates on data structures and graphs; the contrast here is between the intricate structure of the underlying problems and the short and crisp pieces of pseudocode that solve them.

Part III deals with the "sledgehammers" of the trade, techniques that are powerful and general: dynamic programming (a novel approach helps clarify this traditional stumbling block for students) and linear programming (a clean and intuitive treatment of the simplex algorithm, duality, and reductions to the basic problem).

Part IV is about ways of dealing with hard problems: NP-completeness, various heuristics, as well as quantum algorithms, perhaps the most advanced and modern topic. As it happens, we end the story exactly where we started it, with Shor's quantum algorithm for factoring.

Each chapter is a pdf file, and the whole book is also available as a pdf.

Linux Client Migration Cookbook - Version 2

The 2nd version of IBM's Linux Client Migration Cookbook has just been published and is now available as a pdf download.

This free book includes some technical “how to”, but the overall focus of the content is to walk through the important considerations and planning issues you could encounter during a migration project of migrating Windows clients to Linux clients. Within the context of a pre-existing Microsoft Windows-based environment, a more holistic, end-to-end view of the technical challenges and methods necessary to complete a successful migration to Linux-based clients is presented.

This second version of the Linux Client Migration Cookbook builds on the content strategy that was started in the first version. The primary audience for this book is existing business IT environments that need to begin an evaluation of desktop Linux, or in a broader sense any organization whose strategy is to move toward greater adoption of open source software and open standards. For this version the authors have added a significant amount of new content, and have focused on some key areas, such as the following:

  • Greater emphasis on illustrating the technical details of the Linux client operating system stack, and understanding how to best leverage those differences in a migration scenario from Microsoft Windows
  • The tremendous amount of flexibility that Linux gives you to design custom client operating system images
  • Deployment models: understanding how Linux's flexibility allows for new, innovative, and cost effective approaches to deploying and managing desktop operating systems
  • In larger IT environments, the importance of automating capture and migration of end user's client-side personalization data

2 Excellent UML Tutorials

Here are 2 excellent and well written UML Tutorials, one hosted by Sparxsystems.com.au (UML Tutorial), and the other by Borland.com (Practical UML: A Hands-On Introduction for Developers). These will give anyone unfamiliar with the UML a thorough understanding and kick start to using this modeling language.



UML Tutorial

The Unified Modeling Language (UML) has quickly become the de-facto standard for building Object-Oriented software. This tutorial provides a technical overview of the 13 UML. diagrams supported by Enterprise Architect.UML 2 semantics are explained in detail in the new UML 2.0 tutorial.

But first... What is UML?

The OMG specification states:

"The Unified Modeling Language (UML) is a graphical language for visualizing,
specifying, constructing, and documenting the artifacts of a software-intensive system.
The UML offers a standard way to write a system's blueprints, including conceptual
things such as business processes and system functions as well as concrete things such
as programming language statements, database schemas, and reusable software
components."

The important point to note here is that UML is a 'language' for specifying and not a method or procedure. The UML is used to define a software system; to detail the artifacts in the system, to document and construct - it is the language that the blueprint is written in. The UML may be used in a variety of ways to support a software development methodology (such as the Rational Unified Process) - but in itself it does not specify that methodology or process.

UML defines the notation and semantics for the following domains:

- The User Interaction or Use Case Model - describes the boundary and interaction between the system and users. Corresponds in some respects to a requirements model.
- The Interaction or Communication Model - describes how objects in the system will interact with each other to get work done.
- The State or Dynamic Model - State charts describe the states or conditions that classes assume over time. Activity graphs describe the workflow's the system will implement.
- The Logical or Class Model - describes the classes and objects that will make up the system.
- The Physical Component Model - describes the software (and sometimes hardware components) that make up the system.
- The Physical Deployment Model - describes the physical architecture and the deployment of components on that hardware architecture.

The UML also defines extension mechanisms for extending the UML to meet specialized needs (for example Business Process Modeling extensions).

See also Business Process Modeling (pdf) .

If you have any suggestions or comments on the material here, please forward your thoughts to sparks@sparxsystems.com.au.


UML Tutorial - Continued - Use the UML to Define and Build Systems

We have established in Part 1 that the UML is a language for specifying the artifacts and interactions of a software system. We have also seen that it deals with 6 major domains - from Use Case models, through dynamic and logical models to the final physical deployment model - and that extension mechanisms have been included to allow for specialised additions to the model notation.

So... How do you use the UML?

The UML is typically used as a part of a software development process, with the support of a suitable CASE tool, to define the requirements, the interactions and the elements of the proposed software system. The exact nature of the process depends on the development methodology used. An example process might look something like the following:

1. Capture a Business Process Model. This will be used to define the high level business activities and processes that occur in an organization and to provide a foundation for the Use Case model. The Business Process Model will typically capture more than a software system will implement (ie. it includes manual and other processes).
2. Map a Use Case Model to the Business Process Model to define exactly what functionality you are intending to provide from the business user perspective. As each Use Case is added, create a traceable link from the appropriate business processes to the Use Case (ie. a realisation connection). This mapping clearly states what functionality the new system will provide to meet the business requirements outlined in the process model. It also ensures no Use Cases exist without a purpose.
3. Refine the Use Cases - include requirements, constraints, complexity rating, notes and scenarios. This information unambiguously describes what the Use Case does, how it is executed and the constraints on its execution. Make sure the Use Case still meets the business process requirements. Include the definition of system tests for each use case to define the aceptance criteria for each use case. Also include some user acceptance test scripts to define how the user will test this functionality and what the acceptance criteria are.
4. From the inputs and outputs of the Business Process Model and the details of the use cases, begin to construct a domain model (high level business objects), sequence diagrams, collaboration diagrams and user interface models. These describe the 'things' in the new system, the way those things interact and the interface a user will use to execute use case scenarios.
5. From the domain model, the user interface model and the scenario diagrams create the Class Model. This is a precise specification of the objects in the system, their data or attributes and their behaviour or operations. Domain objects may be abstracted into class hierarchies using inheritance. Scenario diagram messages will typically map to class operations. If an existing framework or design pattern is to be used, it may be possible to import existing model elements for use in the new system. For each class define unit tests and integration tests to thoroughly test i) that the class functions as specified internally and that ii) the class interacts with other related classes and components as expected.
6. As the Class Model develops it may be broken into discrete packages and components. A component represents a deployable chunk of software that collects the behaviour and data of one or more classes and exposes a strict interface to other consumers of its services. So from the Class Model a Component Model is built to define the logical packaging of classes. For each component define integration tests to confirm that the component's interface meets the specifcation given it in relation to other software elements.
7. Concurrent with the work you have already done, additional requirements should have been captured and documented. For example - Non Functional requirements, Performance requirements, Security requirements, responsibilities, release plans & etc. Collect these within the model and keep up to date as the model matures.
8. The Deployment model defines the physical architecture of the system. This work can be begun early to capture the physical deployment characteristics - what hardware, operating systems, network capabilities, interfaces and support software will make up the new system, where it will be deployed and what parameters apply to disaster recovery, reliability, back-ups and support. As the model develops the physical architecture will be updated to reflect the actual system being proposed.
9. Build the system: Take discrete pieces of the model and assign to one or more developers. In a Use Case driven build this will mean assigning a Use Case to the development team, having them build the screens, business objects, database tables, and related components necessary to execute that Use Case. As each Use Case is built it should be accompanied by completed unit, integration and system tests. A Component driven build may see discrete software components assigned to development teams for construction.
10. Track defects that emerge in the testing phases against the related model elements - eg. System test defects against Use Cases, Unit Test defects against classes & etc. Track any changes against the related model elements to manage 'scope creep'.
11. Update and refine the model as work proceeds - always assessing the impact of changes and model refinements on later work. Use an iterative approach to work through the design in discrete chunks, always assessing the current build, the forward requirements and any discoveries that come to light during development.
12. Deliver the complete and tested software into a test then production environment. If a phased delivery is being undertaken, then this migration of built sofware from test to production may occur several times over the life of the project.

Note that the above process is necessarily brief in description, leaves much unsaid and may not be how you work or follow the process you have adopted. It is given as an example of how the UML may be used to support a software development project.

Practical UML: A Hands-On Introduction for Developers

by Randy Miller
Abstract: This tutorial provides a quick introduction to the Unified Modeling Language™

The heart of object-oriented problem solving is the construction of a model. The model abstracts the essential details of the underlying problem from its usually complicated real world. Several modeling tools are wrapped under the heading of the UML™, which stands for Unified Modeling Language™. The purpose of this course is to present important highlights of the UML.

At the center of the UML are its nine kinds of modeling diagrams, which we describe here.

Some of the sections of this course contain links to pages with more detailed information. And every section has short questions. Use them to test your understanding of the section topic.

Why is UML important?

Let's look at this question from the point of view of the construction trade. Architects design buildings. Builders use the designs to create buildings. The more complicated the building, the more critical the communication between architect and builder. Blueprints are the standard graphical language that both architects and builders must learn as part of their trade.

Writing software is not unlike constructing a building. The more complicated the underlying system, the more critical the communication among everyone involved in creating and deploying the software. In the past decade, the UML has emerged as the software blueprint language for analysts, designers, and programmers alike. It is now part of the software trade. The UML gives everyone from business analyst to designer to programmer a common vocabulary to talk about software design.

The UML is applicable to object-oriented problem solving. Anyone interested in learning UML must be familiar with the underlying tenet of object-oriented problem solving -- it all begins with the construction of a model. A model is an abstraction of the underlying problem. The domain is the actual world from which the problem comes.

Models consist of objects that interact by sending each other messages. Think of an object as "alive." Objects have things they know (attributes) and things they can do (behaviors or operations). The values of an object's attributes determine its state.

Classes are the "blueprints" for objects. A class wraps attributes (data) and behaviors (methods or functions) into a single distinct entity. Objects are instances of classes.
