Description:

Help Koha's OPAC take the last steps back to being WCAG 2.1 AA compliant. Koha generally has a great track record for catering for all in the community and that includes a focus on the software itself meeting these accessibility guidelines.

In this workshop, we hope to work together on bugs that bring us up to this standard. PTFS-Europe has committed to taking on some of the more involved piece before the event and needs your help with testing, signing of and working through quality assurance. There's also a few area's where we need more hands on the code and we intend to run a few bug fixing demo's where we fix an issue in one place and the same workflow can be used to fix the same issue elsewhere.

The workshop will be open to all, and will be a great way for attendees to see how Koha gets built from our development processes and testing processes. Anyone can lend a hand with testing using the public sandboxes and those wanting to try out coding can quickly get up to speed with koha-testing-docker, our go to development tool.

Description:

Kelly and Jessie created Monday Minutes, a weekly VLOG, dedicated to educating users of Koha. The goal is to break down a feature, workflow, or system preference into bite sized tutorial videos. Kelly and Jessie will provide guidance on how to support change as an individual, as a library, or as a Koha community member. Koha has seen dramatic changes in the last few releases, including an entirely new UX design for the staff interface, an ERM module and more robust CMS features, making it incredibly easy for staff to create pages on the OPAC. We will discuss change management and demonstrate some of these features and how you can champion the process. In addition, we will talk about the Koha community and how to really get involved to assist in the future of change.

The goal for the presentation is to discuss change management techniques for staff and the importance of being a leader for change in the library or yourself. We will demonstrate new features and enhancements that have been introduced in the last year and how users can utilize these changes to educate staff, enhance the library experience and most importantly get excited for new changes. The outcome is to walk away with passion and motivation to bring that change back to your library or company support staff!

Description:

This talk is open to anyone, whether their interest is in Koha or in Perl! When starting with PTFS Europe, I had never worked with Koha or with Perl before and found myself on a steep learning curve. I also had two new colleagues in a very similar position and the aim of this talk is to outline our experience as new developers in both the Koha and Perl communities and the different opportunities (and challenges) we encountered along the way. Hopefully our experience can be used to identify areas that could be improved/advertised to bring more new developers into the Koha and Perl communities.

General outline:
Who am I? / Who are PTFS / Meet the team
First steps in Koha / Perl
Resources used to learn/develop in both
Challenges faced
Community involvement and friendlyness
What could be done to bring others in?
Future plans in Koha and Perl

Tux Machines (established 2004) is a popular news site focusing on Free/Libre and Open Source Software, especially GNU/Linux. Last year it moved new content from Drupal to a proper, Perl-based, static site generator to produce both a web site and a Gemini capsule in parallel. The underlying goal has been to keep things as simple as possible but no simpler. There are four aspects to be covered: the choice of CPAN modules, the role of the perl scripts, the underlying SQLite database and its Dublin Core Metadata schema, and lastly the overall publishing workflow. The work is tracked in self-hosted Git.

So you want to make a change to Koha's codebase? This will tell you where to get started and what it takes to succeed. Koha's QA process aims to find all the bugs and make sure we have good code quality, but there is a bit more to it. By requiring more than one set of eyes checking functionality and code, we encourage communication, teamwork and transfer of knowledge. We welcome every new contributor and are very happy to help you learn along the way.

Description:

PayProp's batch systems are scheduled by crontabs. We want to be able to replay history to test refactored code against the original, to give us coverage for corner cases - especially the unknown unknowns.

Knowing when a given crontab line runs - plenty of choices. But putting different commands in crontab in order - nothing did this.

Hence Cron::Sequencer.

This talk starts with an overview of the module and the problems it sets out to solve. But "no plan survives contact with the enemy" - when the code was 80% complete I realised I needed to redesign the internals. So the second 80% of the talk covers how I solved this, explaining several obscure but very useful features of Getopt::Long

Description:

Have you heard about library discovery layers but wondered exactly how they're different from the Koha OPAC? Are you curious to learn more about what your library users might gain if you add library discovery? Are you interested in what open-source options are available for library discovery? In this presentation Arthur Suzuki from BibLibre and Jordan Fields from ByWater Solutions will introduce you to the key functionality provided by discovery layers, explain why it is beneficial to have library discovery alongside Koha, demonstrate key features of the Bokeh and Aspen open source library discovery solutions, and discuss the necessary ongoing Koha development to support integration with tools like discovery.

Goals of the presentation:
1. Introduce attendees to what library discovery software is and what it can do
2. Help attendees understand the advantages of having this type of software exist alongside Koha
3. Demonstrate two different open-source discovery software options that work with Koha
4. Discuss what is necessary in Koha development to support discovery software

Description:

In this talk, I will introduce you to my open-source learning project designed for beginner developers.
Highlights:
- Identical features implemented in four different languages: Perl, PHP, Python, and JS.
- Developed using Mojolicious, Slim, Flask, and NodeJS within Docker.
- Includes smoke tests and sample CI/CD pipelines.
Follows a commit-by-commit learning approach, where each commit is a self-sufficient functioning entity. The complexity increases with each commit. This enables learners to grasp differences between frameworks and languages and empowers them to contribute to the project by introducing more intricate concepts, explanations, and documentation.

Metsätalo, Hall 6 (Sali 6)

Description:

Creating SQL queries with placeholders is a must. But composing strings with interpolation is easier and better to read. How about combining the best of both worlds?

Many are still composing their SQL queries dangerously by assembling their queries with string interpolation.

Not only are such queries slow and prone to errors, they are also loopholes for injections. But many legacy projects are full of such examples. And refactoring is often not easy.

And even today many developers choose interpolation, since it's a core feature in Perl and comfortable to use.

This talk shows a current project to convert such interpolations to placeholders, without losing the benefits of ease and expressiveness.

We will cover and explain some in-depth techniques like

- Callbacks in DBI.pm
- Manipulating variables with PadWalker.pm
- Bind variables with tie
- Overloading operators for objects

Description:

Ansible is a very pragmatic and powerful IT automation platform. There is no need for a central server or an agent on the target server. As long as the server has a Python interpreter and can be reached through a SSH connection, it can be configured by Ansible. The main components are the inventory (servers, groups and variables), and the playbook (defining tasks and using modules and roles).

The talk revolves around the setup of a Sympa mailing list manager instance with the related infrastructure (database, web server and mail server) through Ansible and several roles.

In particular we look at Perl related tasks as:
- Install cpanm script with Ansible
- Use Ansible cpanm module to deploy Perl Apps
- Install DBI drivers
- Executing Perl scripts with the command module
- Writing Ansible modules in Perl

This talk will discuss the process of future goal setting in open collaboration, specifically the case of the scientific Koha Finland road map for 2030. As part of university or other organizations, scientific libraries are obligated to follow the future goals of the university and other organizational rules and practices. This presentation will highlight the background and process of making future plans for the scientific Koha Finland during the years 2021 and 2022. The resulting road map includes shared values, strengths, weaknesses, and future actions to be taken. The talk will also discuss the value and meaning of future goal setting process from the communicative constitution of organizing theories viewpoint. The presentation will demonstrate the importance of having a process that produces durable actors, such as future road maps, in order to reduce ambiguity of various interests and fuzzy communication in open consortia. Finally, the position of this process and outcome will be presented in the national level context to highlight the multiverse of different strategies and future plans of higher education institutions in Finland.

A long string of alternating White and Black Queens, and a single Regular Expression is you need to solve the N-Queens problem!

A staple for new Computer Science students and a favourite topic for interview questions is to write a program to solve the N-Queens problem: find a way to place N Queens on an NxN chess board such that no two Queens attack each other.

This is what we are going to do in this talk, but our language of choice is going to be the language of regular expressions.

Once we're done with just placing Queens, we will expand the problem and use regular expressions to place multiple, different pieces on the board, in such a way no two pieces attack each other.

Master this technique, and leave a lasting expression during your next job interview.

Description:

ssh clients, database clients and similar can prompt you to enter a sensitive password from the terminal. That way, it's never exposed on the command line or in a configuration file on disk.

At work, we wanted the option to do this with our database wrapper if there is a terminal, but if there isn't, fail fast and loud, rather than hanging forever.

We needed tests for both scenarios, but when we write tests we're doing so interactively - how do we test the tests?

Hence Test::NoTtty - a helper to "run this block of code as if it's non-interactive", so we can successfully fail anywhere.

Description:

Rex is a friendly automation framework. It acknowledges that "there is more than one way to manage it", and puts the user in charge of how it is best to approach their situation at hand. It's easy to get on board, making it friendly for incremental development. It's also based on Perl, which enables harnessing the power of a vast ecosystem of well-established tools and workflows.

As a long-term maintainer, I'm exposed to many common or even unexpected use cases with Rex. I'd like to share the most important ones, in order to to help orient yourself about the different trade-offs compared to other popular approaches.

Description:

Aspen Discovery is an open source discovery layer that works with Koha and other ILS systems to allow patrons to easily find all of the amazing content that libraries own including physical materials, electronic content, web content, genealogical data, articles and databases, and much more. Aspen Discovery also allows administrators to create content including themes, translations, web pages, placards, lists, etc. Over the past few years the libraries we work with have expressed interest in being able to share this content to be able to better collaborate with each other and save time. This year we've been busy building the infrastructure to enable this sharing and we've been working with libraries and partner organizations to discuss norms and best practices for sharing.

In this presentation we'll talk through the technical details of our content sharing solution, share some examples of content that libraries have shared, and discuss some of the lessons learned about helping library collaboration.

Description:

At my employer we have of batch scripts, which were written ages ago, do their thing wonderfully, and reliably earn their keep month in month out.

Problem is, that we want to edit some of them. They don't have tests. They were never written with testing in mind. We'd need to refactor them to easily write tests for them, but we don't want to refactor them *until* we have tests.

How do we solve this conundrum?

This talk will explain the techniques we developed to run scripts in testing byte-for-byte unchanged, but with code injected so that we could subvert the control flow to write thorough tests.

Don't do this at home.
Don't do this in production.
Don't do this in new code.
But, if you have a problem... if no-one else can help...
Maybe you can hire... The A-Team.

Not everything (well, hardly anything) needs Kubernetes and a fully automated CI pipeline. Sometimes it's enough to use well-established & boring techonlogy to get your code to production.

In this talk I'll show how I deploy a medium-sized app stack by building and deploying Podman containers using make (to automate and document the necessary steps) and Ansible (to prepare the node and manage systemd files etc)

Description:

National Repository Library uses a macro to facilitate routine work in the Koha library system. About 10 people describe the material daily in the National Repository Library, but only one person at a time can give the final shelf location to a publication. The describer first gives to the publication a temporary location (his/her own initials) and later he/she gives the final shelf location for several dozen publications at a time. Shelving takes place in the order of arrival (numerus currens), so the exact order in assigning locations is very important. In this routine work we use a macro to help us and keep the collection in order. This macro retrieves the publication according to its id-number, asks for the permanent location, and finally saves new location and asks id for the next publication until user ends using the macro.

You may have heard murmurs about Indigenous Data Sovereignty, but what is it exactly? And how does it affect libraries?

During this talk, we will explore the following:
• What is Māori Data Sovereignty?
• Examine what Indigenous Data is.
• How, as library and information professionals, can we help or hinder this movement?

This will be a taster and hopefully will give you the appetite to learn more about Indigenous Data Sovereignty in your part of the world.
Attendees will be able to under the idea of data sovereignty and how it relates to their library's own data collection and retention policies and procedures.
