The slides and details are still linked off the 2001 YAPC website or directly at <http://www.criticalintegration.com/gtk-tutorial/>
Gtk is a graphical toolkit for building X11 based graphical applications. This tutorial assumes perl knowledge and is not for novices.
The first 20-30 mins or so of the tutorial is a background of Gtk, why, where and how. It emphasises the change in style from the more familier "straight line" programming to the seeming chaotic event-driven programming which is the fundimental of all Graphical programming.
The nasties of packing, boxes and getting used to the idea of giving up control.
A basic crib-sheet of basic widgets, functions and methods will be provided. This I found last year would be vital, as the process of re-affirming syntax via the slides is too time-consuming.
Then the fun starts.
A basic application requirement will be taken from the floor, and the application will be designed using pen and whiteboard. The structure will be explained, pitfalls will be purposefully fallen into to give the attendee a good basic understanding of how to write (and how not to write) basic X11 applications.
Last year, the application was the "Dutch Auction" program which was used at the end of YAPC::Europe.
Learning from the tutorial last year... I will be stricter on answering "pedant" questions like "Why don't you use a foreach loop" instead of assigning individual assignments. (Readability)

This is about software development: when a tiny feature in a module gets implemented in a correct way, this one line of code gets encapsulated in subroutines/methods, documentation, tests, etc. This is about the difference between "solving my problem", which is the daily practice for writing applications, and "solving your problems", which is required for CPAN modules.

SOAP started life as the Simple Object Access Protocol, one of the productions of the W3 Consortium's XML Protocol working group. It defined a relatively lightweight means of doing Remote Procedure Calls (RPC) using XML over a pre-existing network transport protocol. The 1.2 version of the specification somewhat downgraded the acronym SOAP as features were added which probably meant that it not quite so Simple anymore and the RPC 'Object Access' simply became one of the ways in which the protocol be used for communication between systems.
Perl has, for quite some time, had good support both for XML processing and for handling a variety of common network transport protocols and thus was in a good position from the start to be able to provide good support for SOAP and so was able to take its deserved reputation as an excellent 'glue language' further beyond the boundaries of a single system or application than it previously had done and into the arena of application integration - previously the preserve of expensive and complicated middleware.
This will talk will include a a brief introduction to the history of and the rationale behind SOAP and the reasons why Perl was in a good position to be an early language for which a toolkit was available to build SOAP applications.
The remainder of the talk will focus on the use of Perl and SOAP in the integration of diverse applications and will include discussion of:
There will be working examples demonstrated in Perl and C++ (and possibly C# or Java) although this will be at a higher level than a tutorial.
This should serve both as an introduction to using SOAP with Perl for the uninitiated and also as a demonstration to people already familiar with it some further ways that it can be used.

For the past two years Perl 5.8 has been one of the worst hidden skunkworks ever. Conceived approximately at the same time as the much publicized Perl 6 project, 5.8 (clandestinely disguised as 5.7) has made major enhancements to the Unicode functionality, sprouted a new user-visible threads implementation, silently assimilated several dozen modules, and created some completely new ones. Other new features and enhancements include a new stackable IO architecture, more accurate numbers and arithmetics, restricted hashes, and safe signals. Perl 5.8 is also the most thoroughly tested Perl release ever.
Come to hear what's new, what's changed, and what's gone.

How many hours a programmer will put in his program, and how many bugs he might have solved, and how much of the program is covered with working test code, bugs will probably always be present in the program or script.
The most recent development branch of the Perl code is called bleadperl, and it is patched by many on several parts on a daily basis. For every patch that solves a bug or extends the features of the rich language that Perl offers, other functionality might get busted or slightly broken.
Testing the latest state in as many configurations as possible on as many operating systems as possible with as many development enviroinments as possible is a great source of information to the perl5 porters. This process has been called ``smoke testing''.
With people working on various parts of the perl core simultaniously: threading and variable sharing, IO subsystems, reported bugs, formatting, configuration and hints, etc. etc., it is likely that minor changes might break basic features and patches liked and accepted by the GNU gcc compiler are rejected by other - more rigorously ANSI - C compilers.
To catch those, it would be good to have every patch tested on all supported platforms as soon as possible. But since bleading edge perl is a development release, it is likely to be far from stable at any point in time, and thus not to be installed by the faint of heart. Core dumps are likely to occur if a snapshot is released without being tested on a variety of configurations.
Test-Smoke is a package of scripts that enables
perl5-porters to receive test reports from users that have spare
CPU cycles and some disk space on their
The talk will deal with the development of what has evolved to Test-Smoke, currently available on CPAN. It will also deal with some differences in compilers, with different OS behaviour, and how new users can participate in this valuable process.
As a side step, some of the parts in the perl source tree are explained briefly but not profound and not to show what the implications might be of what smoke testing detects.

The following bit is stolen directly off <http://poe.perl.org> (all good things stem from there):
POE parcels out execution time among one or more tasks, called sessions. Sessions multitask through cooperation (at least until Perl's threads become mainstream). That is, each session returns execution to POE as quickly as possible so it can parcel out time to the next.
POE includes a high-level component architecture. Components are modular, reusable pieces of programs. They perform common, often tedious tasks so programmers can work on more interesting things.
Several POE components have been written to handle client, server, and peer networking tasks. Because of them, POE has become a convenient and quick way to write multitasking network applications.
POE supports graphical toolkits such as Tk and Gtk. It is the only Perl programming framework that does this. It also supports Curses, HTTP, and other user interfaces. POE programs can present multiple user interfaces at once.

About the talk
This tutorial is aimed at giving a basic understanding the workings of POE, trying to get the audience to understand how to use POE and to show them some simple programs (or POEgrams). The main obstacle in understanding POE is right at the beginning; it introduces many terms, concepts and technology that might take some time to wrap your ahead around. This tutorials aims to be your guiding light in this process. Once these basics are covered, we can go into the appicatins of POE and teach the audience how to write POEgrams themselves.

As Perl grows more popular, it also becomes more capable. What started out as a modest reporting language can now be found doing practically everything - And practically everything nowadays is network-related. Be it simple CGIs, mod_perl modules, SOAP services, daemons of all sorts, tailor-made protocols... Everything can be easily coded with Perl. However, power comes at a high price. Many people unfortunately write highly insecure software - This can backfire on themselves or on any other member of the Perl community, as we often share our code. In our talk, we present some examples on what to do, what NOT to do, and how to correctly do it when doing programming. This guidelines should be applied also to non-network-oriented scripts, as they are general enough.

CPANPLUS is a new and flexible method of perl module management and installation, using the Comprehensive Perl Archive Network.
CPANPLUS is a new module. It was born in September of 2001, after that year's YAPC::EU in response to general unhappiness about CPAN.pm. It aims to be a rewrite, and in time a replacement of the current CPAN.pm, but in a completely OO model, adding features unknown to the current CPAN.pm, such as module uninstall, multiple shells and so on. Not in the least, it aims to fix various bugs of CPAN.pm as well as being very modular in its build setup, thus allowing many plug-ins. For example, with a plug-in to the RT bug tracking system, CPANPLUS could send in automatic bug reporting in case a module failed to install.
About the talk
I have given the 90 minute talk about CPANPLUS to Amsterdam.pm and it was very well received. However, it also went into the technical depths of the module and reviewed the history of development, as well as covered the basic knowledge required to develop new applications using CPANPLUS. Although this is very useful information, it's perhaps better suited for a BOF session. In short, I could range the talk from 25 minutes, covering just the bases for the average user, to 90 minutes, covering development, guts, interfaces, features, bugs, direction and so on of the module.
Some more information about the module can be found on the project's homepage at: <http://cpanplus.sourceforge.net>

When perl is not quite fast enough - or /sacrificing (?:style|maintainability) on the altar of speed/
by Nicholas Clark ; 40' talk
There are times when your perl script just isn't fast enough, and the "obvious" solutions (find a better algorithm; use Inline; rewrite it in another language; etc) are either impractical or politically unacceptable. This talk will describe how to find ways to re-write your perl code to go significantly faster, trading style and maintainability for speed. Serious speed gains are possible, even for already well designed code. Examples will include how I made ext/Encode/bin/enc2xs in the perl 5.8 distribution take significantly less time to deliver the same output.
This would be a talk mostly about the work behind some of the terse comments in enc2xs such as:

ELEKTRA is the brand name of ALCATEL Austria's electronic railway interlocking system, installed on more than 70 sites in three countries. Laboratory testing of the system requires the simulation of all the peripheral equipment (points, signals, etc.) and their controlling interfaces. This simulation and the related test environment has been implemented as a set of Perl programs.
Perl 5 was chosen as the implementation language because its promise of portability, the rich set of built-in functions and library packages and the existence of Perl/Tk. Object orientedness was expected to support code reuse.
The simulation of peripheral equipment is done by EPS/Simulation, a server program. Instead of interfacing with the actual hardware, the ELEKTRA equipment controllers set up socket connections as clients to the simulation server. Output commands are passed on to the server which distributes them to the appropriate object, where an evaluation method computes the reactions. Status changes are returned as input to the equipment controller.
EPS/Interface is another client for EPS/Simulation. It provides a graphical user interface showing a canvas map of all trackside equipment and featuring popup windows for all elements. User interactions permit changes in the states of the elements (e.g. occupying or freeing a track section).
Running regression tests is supported by EPS/Batch, an extensible command interpreter. During ELEKTRA system tests it operates as a client to EPS/Simulation, using commands for changing element states. Another connection links this program with an ELEKTRA node for sending simulated operator inputs on mouse and keyboard and for retrieving screen dumps of the ELEKTRA monitors documenting the system status.
Yet another client for EPS/Simulation is EPS/Move, a simple program capable of simulating train movements from a start signal, following tracks and points until a signal showing halt is encountered.
EPS/Track Editor is an offline tool for drawing canvas maps for EPS/Interface.
Simulating a Relay Interlocking System
Since ELEKTRA is also capable of providing a user interface for relay-based interlocking systems the simulation provided by EPS/Simulation also had to include one set of elements corresponding to those that can be found in a relay interlocking system. The simulation of this element group includes interlocking features such as train and shunting route selection and cancellation, and various operations on points, signals and other equipment.
Some Interesting Features
Element (i.e. object) states are communicated via sockets. This is done by sending key-value pairs as plain text, with the receiver eval-ing them into its copy of the object.
The considerable number of objects that need to be shown in the GUI of EPS/Interface is managed by describing each object by its set of output and input lines and external states. The corresponding popup-window is generated from this description.
EPS/Batch uses dynamic loading of code implementing various additional sets of commands. Thus, EPS/Batch is not only used for ELEKTRA system tests but also for MMI and equipment controller subsystem tests. Extension can be written according to a simple command pattern, using a simple interface provided by the core of EPS/Batch.
Development began with 5.005_03 on Solaris which turned out to be very stable and reliable. Later on, 5.6.1 was used (Solaris an Linux), again without any problems. Using Perl/Tk was difficult at times, mostly because of the lack of examples for the more advanced features.

Psychometric tests are now a standard part of many recruitment processes. Traditionally these are hand-scored by qualified psychologists, at great expense and with a long delay between taking the test and getting the results. We were approached by a company who wanted to produce these tests on-line, so that companies could get instant results from candidates who sit the test.
They wanted a system that they could use to set up different tests for different clients, enter the scoring rules (which could be different for different types of tests), and have the system produce reports on each candidate who sits the test. This was to be web-based and browser-independent, and the 'look and feel' of each test should be easily customisable to look like each client's own web site.
And, of course, it had to be completed in several weeks at minimal cost.

The National Software Reference Library (NSRL) is designed to collect software from various sources and incorporate file profiles computed from this software into a Reference Data Set (RDS) of information. The RDS can be used by law enforcement, government, and industry organizations to review files on a computer by matching file profiles in the RDS. This will help alleviate much of the effort involved in determining which files are important as evidence on computers or file systems that have been seized as part of criminal investigations . The harvesting of file profiles from software is accomplished by multiple computers in a loose parallel computing environment. The implementation of the environment is discussed, with attention to performance improvements using reverse regular expressions known as "sexeger".

Nemo is TeXmacs with Perl. Nem, Niki, Nirc and Nile will be the Nemo tool thanks to TeXmacs and Perl.
TeXmacs is an interactive documentation tool with a power comparable to TeX. It does not include or use any TeX code except for font handling, neither emacs code; but, in addition to a menu-driven interface, it supports keyboard accelerators in a way comparable to emacs but somehow different too because TeXmacs has a more complex and (currently) specialized purpose.
TeXmacs is already used to write complex articles and books with complex maths, TOCs, indexes, footnotes... The current main hindrance is more sociological than technical, as editors prefer to receive Word or TeX documents.
TeXmacs is GPL, available on Unices with X-windows system. It is written in C++, currently uses Guile as an extension language and its own widget library. I have near completed a shallow port using Qtapplication event loop that will be quickly followed by a shallow Perl embedding including a Qt adaptator for POE. Watch CPAN and look for mQT and POE::Kernel::mQt within a week! After that, a complete port to Qt will be done to facilitate port toward non unix-like-systems. The Perl interpreter will eventually have more access to the TeXmacs internal structures.
The Nemo project will eventually culminate in a year or two in Nile (Nemo Interactive Literate Environment) with dynamic syntax hiliting that will support languages like per6 with an unlimited number of Unicode operators. More, Nile opens to these languages the full expressivness of mathematical notation (indices, exponent, matrices...). Think of Nile as literate IDE.
I will present TeXmacs as seen by users, will move to how to a quick review of TeXmacss internal and file format, then will explain how to extend TeXmacs using Perl. Finally I will expose the basic rudiments behind the upcoming parsing/deparsing engine behind Nile, the upcoming interactive literate environment. Steps toward Nile will be Nem (concurrent edtions over the net), Niki (a wiki), Nirc (a TeXmacs client that supports Math Notations).
I expect my presentation to be about an hour. It will be in (non native) English. Depending on my progress in the mean time, the presentation may better fit in 1 hour 30
Material needed (I don't have it): a laptop connected to the net with a recent version of linux, a recent TeXmacs and a recent g++ compiler. A source perl distro too. :)

This talk shows how to build large scale websites or web applications with Embperl. It discusses the concept of separation of application logic, display logic, content and layout and how this separation can be achieved with Embperl 2.0.
First, the talk shows the importance of application objects and how they are created, how to break up whole pages into components and how Embperl's inheritance model is working and what are its benefits.
It then continues with a short introduction into Embperl's processing pipeline, which allows the creation of component output within multiple transformations, giving the possibility to include nearly every data source (like e.g. POD, XML, RSS, SSI, CGI scripts or plain text) and rendering techniques (like e.g. JSP, ASP or PHP).
The talk will comprise embedding Perl into HTML, using static XML, generating XML dynamically, doing XSLT transformations and using XSL-FO to generate HTML, XML, PDF, text and various other output formats.
It will also touch other features being necessary to build large scale websites like session handling, caching, database access and internationalization.

In the last few years, e-mail developed from an application used by a relatively small scientific community into a basic means of communication for everyone. Companies have added e-mail as a new way to keep in touch with consumers, next to the traditional postal and telephone services. Friends post birthday invitations by e-mail, and the pictures of the last family meeting are broadcasted to everyone on them.
Creative new practices for e-mail include spam and spreading viruses. Jokes are not posted in plain text anymore, but preferably as PowerPoint presentations. Plain text is not nice at all: let's send HTML or -even better- full Word and PDF documents to everyone we know!
The concept of e-mail has changed, and with it the need to control that flow has increased. Filters which automatically remove received spam, virus checkers, and message content converters are more and more implemented. At the same time, mail folders grow rapidly in size. The number of messages to read daily explodes. How to cope with that?
The recently developed Mail::Box module is capable of handling various kinds of mail folders and replaces many older Perl modules (like MailTools) with components which are better suited for the current generation of messages. The module supports many advanced features which can help implementing the filters you need.
Some features of Mail::Box, Mail::Address, and MIME::Types will be discussed. A few small programs will be explained. Although Mail::Box is fully Object Oriented, only little OO is really needed to understand the examples.

About the Contents
Most of the material I will be using is based on the OO tutorials I wrote, which can be found at <http://japh.nu> I wrote these as a response to many questions on the firstname.lastname@example.org mailinglist. Every day, at least a few questions about OO programming would be asked and many of them would have been answered if the users had read Damian's book or Advanced Perl Programming. When people inquired why they hadn't done so, the majority answered that most concepts introduced in the afore mentioned books were over their head. They wanted a simple yet clear introduction to both the vocabulary and the concept of OO perl.
About the talk
This tutorial aims to be just that: an introduction to both the vocabulary and the concept. It requires only basic perl knowledge, and assumes no knowledge of other languages or OO programming in general. I will attempt to divide the talk into a few chapters, aimed at not only helping the audience understand both concept and vocabulary, but also teaching them how to apply this knowledge in their first attempts at their own modules. After attending this talk, both Damian's book as well as Advanced Perl Programming are recommended literature and should no longer be as elusive.

This talk comes standard with a wee bit of swearing. It can be censored however, but I'd rather do that on the basis of what the audience wants.
As workers in an industry we keep trying to find a metaphor for what we do, rather than just explaining it. We tend to be proud of our achievements inside our technical community. However outside of that tight knit group we tend to clam up when it comes to explaining what we do and how we do it to our friends, families, and random people we meet while drinking. The metaphor approach is not working. No one outside of a software background seems to have any understanding of why its hard to change something six months after the development starts primarily because they don't understand what it is we do. There are very simple measures we can and should take as software professionals (more or less) that attack this problem before it gets any more uncontrollable.

Other features you might not see on first sight, are full Unicode support (because this servlet is written for perl 5.8.0) and incremental indexing and de-indexing (we haven't used this feature at O'Reilly because we have no control over the changes in the documents, but you can watch the incremental indexing feature at <http://netlexikon.akademie.de/query> ).
A working snapshot of the full source code of the O'Reilly servlet is included in the CVS version of WAIT at sourceforge.net. We would wish that the publication of the servlet encourages you to hack your own search engine.
We (Ulrich Pfeifer and me) would like to thank O'Reilly Germany for giving us the opportunity to experiment with 5.8.0 and WAIT in a real-world scenario.
