#1. Introduction to Pyparsing: An Object-oriented Easy-to-Use Toolkit for Building Recursive Descent Parsers

PaulMcGuire

pyparsing is a pure-Python module, containing a class library for easily creating recursive-descent parsers. pyparsing's syntax provides tools for both simple tokenization and data structuring and interpretation. I will give an overview of the basic features of pyparsing, and a *very quick* overview of the advanced features. I will close with 3 or 4 application examples, time-permitting. (For more detail on the type of information I have to present on pyparsing, you can visit my SourceForge project web page at http://pyparsing.sourceforge.net.)(I have posted the presentation materials at my personal web page: http://www.geocities.com/ptmcg/python/index.html.)

#2. Agile Documentation: using tests as documentation

Grig Gheorghiu

Agile Documentation means having unit tests serve a double role: testing your code and documenting it at the same time. I borrowed the term "Agile Documentation" from an article called "Double Duty" written by Brian Button.

In the talk, I will show how doctest and epydoc make it very easy to automatically generate documentation in the form of Test Lists and Test Maps. To see how it all integrates together, check out http://agile.unisonis.com/epydoc/blogmgmt/

I will also show how the Django project generates API reference Web pages automatically from doctest-based unit tests.

I will finish my talk by mentioning the Wiki functionality of FitNesse as a mechanism for using acceptance tests as documentation.

The talk is based on the following blog entries I posted:

#4. An Interactive Adventure Game Engine Built Using Pyparsing

PaulMcGuire

A pure-Python command interpreter engine for creating text adventure games. Used as an example of creating a custom "little language", in this case, the domain being a simple text-based adventure game. Provides a complete example of using pyparsing to structure input commands, with an internal Command structure to implement command behavior. (I have posted the presentation materials at my personal web page: http://www.geocities.com/ptmcg/python/index.html.)

#5. Desktop Application Programming With PyGTK and Glade

Michael Urban / Lion Research Center

GTK is the standard toolkit used in the Gnome desktop environment. Python, combined with PyGTK and the Glade visual designer is rapidly becoming the Visual Basic of the Gnome world for quickly and easily building fully featured GUI applications. However, applications written in Python and PyGTK are not restricted to Gnome or Linux. In fact, Python and PyGTK can fill the same roles as Java and Swing when it comes to writing cross-platform desktop applications.

In this tutorial presentation, I will show how to use the Glade visual designer plus the PyGTK module to quickly and easily build GTK applications using Python. Since GTK was originally written for programming the GIMP image manipulation program, we get a lot of very powerful image manipulation capability for free in GTK. As such, the tutorial will be focused around a simple image processing program that will give us the ability to preview images in a file window, load images for viewing, and rescale images. I will close the tutorial by giving a demonstration of a significantly complex real world Python PyGTK application that exercises many of the features of PyGTK including image editing, tables with custom table cell renderers, resizable dividers, and complex data entry forms.

#6. Vertebral Fracture Analysis

Wesley J. Chun / CyberWeb Consulting

Vertebral Fracture Analysis

Several years ago, at PyCon 2003, I presented a general paper on how Synarc, a medical imaging company in San Francisco, developed medical applications using Python. This time, I would like to focus on one specific project which was my primary responsibility as a Senior Software Engineer there.

The VFract application is used as part of a set of radiology services offered by Synarc. In addition to data entry and image digitization, Synarc provides reading services using software such as VFract to obtain critical patient data necessary for pharmaceutical companies participating in clinical trials to determine the effectiveness of developing medicines. The use of such software helps automate and expedite patient assessment during the course of these clinical trials, overall accelerating the time it takes to get new medicines and treatments to market. The use of VFract has consistently resulted in a large portion of the company's annual revenue.

In this talk, we will discuss all four of the VFract applications, the open source components used to build them (specifically the use of Python as the primary development language), as well as what the general system hardware architecture is made up of.

#8. Scripting .NET with IronPython

Martin Maly / Microsoft

IronPython is a fast implementation of the Python programming language on the .NET Framework. While it stays true to the beauty and simplicity of Python language, IronPython offers Python programmers seamless access to the riches of .NET libraries and applications in a fully dynamic environment.

This talk will focus on practical side of utilizing the power of IronPython beyond the interactive console development and exploration. It will demonstrate how to use IronPython to add rich scripting support to existing .NET applications. This will allow us not only to explore and animate the application but also extend its functionality with custom Python code. We will also demonstrate how IronPython can be used to bring together and orchestrate a wide variety of .NET components and services.

This talk is targeted at both Python programmers looking to take advantage the .NET Framework and at .NET programmers looking to learn how Python can make their jobs easier.

#11. Effective AJAX with TurboGears

Kevin Dangoor / Blazing Things LLC

Modern web browsers, combined with programming frameworks like TurboGears, allow for a rich interaction model that was not possible previously. This interaction model, which is commonly being referred to as AJAX regardless of whether XML is involved or not, brings new usability challenges. Just as people have gotten used to browser user interface elements that have become de facto standards, AJAX rises up to challenge user expectations.

This talk, and the accompanying paper, will briefly discuss some of the pitfalls and include demonstrations and code that illustrate ways to do AJAX so that users are pleasantly surprised, rather than frustrated.

Each discussion will include an example implementation done with Python and TurboGears with highlights of how the technique is actually implemented.

Though TurboGears will be used as the demonstration framework, previous experience with TurboGears will not be required to understand the talk or the examples.

The paper and a screencast version of the talk are online.

#12. Stackless Python in EVE Online

Kristján Valur Jónsson / CCP games inc.

The massively multiplayer online role-playing game Eve Online, developed by CCP games in Reykjavík, Iceland, makes heavy use of Stackless Python to implement game features. This presentation shows how Stackless Python has been used throughout the code to create a seamless environment of cooperative multitasking in the game engine and how Python code and C code interacts in a complex real-world environment.

#13. Cuaima MetaInstaller. New tool for managing System Installations.

Ricardo Strusberg / Latinux

Jesus Rivero / Latinux

Carlos Zager / Latinux

The intended use of this timeslot is to introduce "Cuaima" a new Web-Oriented (LGPL) software program we are writing to simplify the installation of custom GNU/Linux Distributions.

Cuaima is a MetaInstaller for GNU/Linux and *BSD Operating Systems that runs on top of a (Python) WebServer to provide local, remote and massive installations of these *NIX flavoured Systems. The installer is capable of installing any kind of Distribution and configuring it properly with preconfigured files or custom parameters such as the Distribution to be installed, user parameters, root's password, network configuration, etc. Cuaima takes the whole process of installation to another level.

Cuaima is written almost entirely in Python. The rest of the code is Javascript for client-side tasks such as field validator's and an implementation of XMLRPC to provide real-time installation-progress information.

Cuaima is part of a larger sets of tools that is in the planning stage now to provide End-Users and Enterprises the ability to create Custom GNU/Linux Distributions for determined and particular uses.

It is proposed that the Cuaima MetaInstaller be the Official Installer for the Official Venezuelan Republic GNU/Linux Distribution.

#14. Osh: An Open-Source Python-Based Object-Oriented Shell

Jack Orenstein / Geophile, Inc.

Osh implements a language that supports the composition of commands through the piping of objects. This language is designed for use from the command-line of an ordinary shell. The objects piped from one command to the next can be Python primitives (numbers, lists, maps, etc.); other types such as dates/times, or database rows; or can represent various OS resources such as files and processes. Conversions between objects and strings simplify integration with the Unix environment. The commands included with osh manipulate objects, access databases, and execute commands remotely, including parallel execution on nodes in a cluster. Data manipulation commands allow the user to invoke functions, including lambda expressions, written on the command line.

Osh is licensed under the GPL. More information and a tarball can be obtained at http://geophile.com/osh.

#16. Decimal for beginners

Facundo Batista

The idea is to let the reader to feel confident about this new data type in order to start using it, from the very beggining, explaining a lot of background concepts the user needs to start to understand floating point and decimal.

The presentation outline is:

#17. Large-scale, cross-platform synchronization using embedded python

Alexis Lê-Quôc / Wireless Generation

Wireless Generation uses python to allow the synchronization of student assessments, from 70k teachers assessing over 1.5 million students. Because python is a high-level language it is fit to solve problems both as an embedded cross-platform client and as a server-side component. This talk will present a few opportunities where python shone on the client-side:

#18. Internet Access via Anti-Virus Policy Enforcement Software and Messaging Service

Jason Hoerr / Albright College, Frank Wilder / P-Wave, Inc.

The presentation will cover the use of Python/wxPython/Perl/MySQL to create a set of tools to control access to the Internet for over 900 personal computers on a college campus. Access to the Internet is based on valid registration of the computer on the college network and the confirmation of a valid antivirus definition file. The tools set consist of a program that runs on each client machine as a service, another program that is used to display messages on the client machine and a set of code that manages the actual connection to the Internet via virtual network switching on Cicso switches based on setting in a MySQL database.

#19. State-of-the-art Python IDEs

Jonathan Ellis / Berkeley Data Systems

This talk will build on the review of 6 IDEs done by the Utah Python UG and summarized here: http://spyced.blogspot.com/2005/09/review-of-6-python-ides.html. In the interest of time, this talk would focus on the most promising four IDEs: Komodo, PyDev, and Wing, which are in the review-of-6, and SPE, which is not.

#21. Developing an Internationalized Application in Python: Chandler a case study

Brian Kirsch / Open Source Application Foundation

Internationalization is the most often overlooked aspect of Application development. It is a mistaken belief that Internationalization can easily be added at anytime. This mistake ultimately results in developers frantically scrambling to patch together a solution for an architecture which was never designed for it. Too many products end up in a rewrite when the team finally discovers just how fundamental a role Internationalization plays.

This talk will cover general concepts on how to design Internationalized Applications, as well as focus in depth on the specific choices made for Chandler including leveraging Open Source libraries and designing for multiple Operating Systems.

#23. Cancelled: Processing XML with ElementTree

Andrew Kuchling / PSF

ElementTree provides a simple library for processing XML that feels natural to Python programmers. This talk is a 45-minute tutorial showing how to perform basic tasks with ElementTree.

#24. What is Nabu?

Martin Blais / Furius

Desktop search tools (e.g. Google Desktop) build a database of the information that is stored on your computer. Wouldn't it be great if some of this desktop database could be used to automatically feed your online blog, or a website?

Also, wouldn't it be immensely useful if the "types" of information found in your documents could be automatically identified? (i.e. a mini "semantic web", but for your own files) For example, by finding all the "addresses" in all of your personal files, you could easily build your address book.

Are you someone who uses plain text files instead of fancy specialized programs to maintain your personal data?

If you find any of the above interesting, this talk is for you. I am proposing a system, Nabu, built in Python using ReStructuredText, Docutils and text files, that can be used to collect "typed" data from those files and fill a remote database with the extracted data. This data can then be used to feed a wiki, a blog, a web site, or any other kind of presentation layer you desire.

Related talks: "Docutils Developers Tutorial: Architecture, Extending, and Embedding" is for those interested in the implementation details of Docutils. "Easy Slide Shows With reStructuredText & S5" describes another application of Docutils.

There will also be a Docutils sprint following the conference.

#25. TurboGears Tutorial

Mark Ramm

I will provide a tutorial for those interested in learning the basics of the TurboGears web programming megaframework.

#26. Packaging Programs with py2exe

Jimmy Retzlaff / Aver Development Corporation

py2exe is a Python distutils extension which converts Python scripts into executable Windows programs, able to run without requiring a Python installation. This talk by the maintainer of py2exe will cover the simple use, options, more complex use, and future of py2exe.

#28. Cancelled: SAGE: Software For Algebra and Geometry Experimentation

William Stein / Dept. of Math., Univ of California, San Diego

#29. Cancelled: Python in Business : Thyme, a business-oriented Python development framework.

John Pinner / Clockwork Software Systems

At PyCon 2005, I presented PayThyme, Clockwork's industrial-strength UK statutory payroll. There was some surprise that we had licensed such a commercial application under the GPL. Since then PayThyme has been used by over 1000 companies and at London's LinuxWorld expo was the outright winner of Best Open Source Application.

PayThyme's development platform is Thyme, our own Python development framework based on Python, C and PyQt. It allows us to develop business applications very quickly indeed.

This presentation describes Thyme, the rationale behind its design, demonstrates it in use, and shows how we are updating and extending it.

#30. Cancelled: Python at Home : In Control

John Pinner / Clockwork Software Systems

Once upon a time, a long time ago, I installed central heating in our home, a wet system with gas-fired boiler and a (then) state-of-the-art control system. Recently I replaced the boiler, but was disappointed to find that there was no modern equivalent to the old control system.

It didn't take long to realise that it shouldn't be impossible to create a new and improved controller using PC technology. After all, all we needed was a few relays to switch things on and off, some temperature sensors to measure what was going on, a spare PC, and some software to glue it all together.

So was born a Python-based project to control our heating system, the objective being to maximise comfort and minimise running costs. It has been both fun and satisfying putting it into practice.

The presentation will describe the control system and its development.

#31. Extending the life of CVS with Python

Anthon van der Neut / Pinnacle SYstems

This talk describes how Python is used to overcome problems, and automate several administrative tasks in a multi-location, multi-project CVS and CVSup-mirroring setup, as well as a flexible build system for sources contained in these repositories.

#34. The State of Dabo

Ed Leafe / The Dabo Project

Dabo is a 3-tier desktop application framework written in Python. Its database tier allows it to be used with just about any relational database backend, such as PostgreSQL, MySQL, SQLite and others. Its UI
