Programming with the Zope 3 Component ArchitectureThis tutorial provides a short introduction to developing with Zope 3. It provides an example of creating a content objects and associated views, adapters, and utilities. The skills learned here are applied in most facets of Zope 3 development.
We Zope to be much more approachable to Python programmers. You should be able to use existing Python objects in Zope with few changes. We want developers to be able to learn Zope a little bit at a time. We provide greater support for reuse through components.
Let's look at a minimal class that is usable in Zope. As an example, we'll use objects that manage personal information.
We normally organize our software into packages. We can put our packages anywhere, as long as they are in Zope's Python path. We'll create a buddydemo package in the src directory, which is in the Python path. We create an empty __init__.py file in buddydemo, so that Python will treat buddydemo as a package. We'll create a buddy.py module to hold our class, named Buddy. The class is very simple. It stores information in attributes. It provides a single method that combines the first and last name. There are no Zope- specific mix- in classes. We do subclass Persistent. Doing so makes our life easier, because then Zope will manage our data in its object database. We don't have to subclass Persistent. If we don't though, we need to manage our data some other way (e.g. in a relational database).

One goal of the project is to make a large number of Java simulations available for education using the GNU Open-Source model. This manual describes some of the classes and interfaces that are being used in this project.
Portions of Open Source Physics are being incorporated into the following:
• Java edition of An Introduction to Computer Simulation Methods by Harvey Gould, Jan Tobochnik, and Wolfgang Christian.
• Statistical and Thermal Physics project by Harvey Gould and Jan Tobochnik.
• Easy Java Simulations high-level modelling tool by Francisco Esquembre.
• Tracker video analysis program by Doug Brown.
Programmers wishing to adopt Open Source Physics tools for their own projects are encouraged to do so provided that these projects release their source code under the GNU Open-Source GPL license. Open Source Physics code is being distributed using CVS from the SourceForge web site:
http://sourceforge.net/projects/os-physics/
Additional curricula material and links are available from the Open Source Physics server hosted at Davidson College
Download pdf Open Source Physics: A User's Guide with ExamplesIntroduction to Publisher 2007Microsoft Publisher 2007 is a really neat program that allows you to create professional quality newsletters, brochures, flyers, postcards, calendars, award certificates, calling cards, paper airplanes, origami – and a whole lot more great “things.”
This tutorial will proceed from what we think is the easiest publication to the most complex. First we’ll create a flyer using Microsoft Publisher 2007. Then, we’ll create a brochure, and finally a newsletter. Each skill we learn in the flyer will be of use in the brochure. The flyer and brochure techniques will also be used in the newsletter. Your abilities will grow from publication to publication. You may save your publications on a formatted 3 ½ inch diskette, a USB key, or on your hard drive.
To load the Microsoft Publisher 2007 program, Double click on the Publisher 2007 icon on the main Windows screen, or click-on Start in the lower left corner of the screen, then click-on Programs, and then click on Microsoft Publisher 2007.
Download pdf Introduction to Publisher 2007Correcting Astigmatism in Diode LasersAstigmatism is an inherent property of the output beam of diode lasers. In applications requiring collimation or transformation of the diode laser’s beam, this astigmatism must be considered, and often corrected, if the final wavefront is to approach the diffraction limit.
Diode lasers are p-n junction devices, where radiation created by injection of carriers across the junction is confined by a tiny optical waveguide. This waveguide, with its plano, partially reflecting end facets perpendicular to the junction, forms the Fabry-Perot cavity of the diode laser.
Two general types of optical waveguides may be found in diode lasers. The first is a dielectric slab, or index-guided, waveguide, in which the optical energy is confined through total internal reflection. This is achieved by surrounding the gain region with layers of material with a lower refractive index. In a gain-guided optical waveguide, in contrast, the energy is confined by surrounding the optical gain region with a region...

Its designed to be easy to use, yet powerful and flexible. GnuCash allows you to track your income and expenses, reconcile bank accounts, monitor stock portfolios and manage your small business finances. It is based on professional accounting principles to ensure balanced books and accurate reports. Getting Started Running GnuCash for the first time The very first time you run GnuCash you will be presented with the Welcome to GnuCash! menu with three choices. The following table describes the contents of the menu.

DownloadPC-REACH for Windows TutorialWelcome to the world of Electronic Funds Transfer (EFT). PC-REACH for Windows is a tool that can help you begin processing your financial transactions electronically. The most common uses are transactions that are done on a routine basis such as payroll, monthly installment payments, rental payments, membership dues, contributions, etc. The benefits are numerous for both credit and debit applications. For company payroll, a savings will be realized in check printing cost (time and paper), distribution, bank reconciliation charges, and employee productivity on payday. Any application for debits will give companies cash flow control never experienced before! Public acceptance of direct deposit payroll and automatic bill payments is prompting businesses to search for Financial Institutions capable of Originating (processing) Electronic Payments.
The following pages take you through easy to follow instructions for installing the program. Although very brief, the Tutorial section is helpful in learning the basics of how to enter a transaction and how to prepare a diskette for bank processing. Naturally more information is available in the User's Manual that is provided with each copy of the program.
Thank you for trying PC-REACH.
