DBIx-DataModel is an object-relational mapping framework for Perl5. Schema declarations are inspired from UML modelling. The API provides efficient interaction with the DBI layer, detailed control on statement execution steps, flexible and powerful treatment of database joins.

Patterns for slick database applicationsSkills Matter
Slick is Typesafe's open source database access library for Scala. It features a collection-style API, compact syntax, type-safe, compositional queries and explicit execution control. Community feedback helped us to identify common problems developers are facing when writing Slick applications. This talk suggests particular solutions to these problems. We will be looking at reducing boiler-plate, re-using code between queries, efficiently modeling object references and more.

Big Data Everywhere Chicago: Unleash the Power of HBase Shell (Conversant) BigDataEverywhere
Jayesh Thakrar, Senior Systems Engineer, Conversant
The venerable HBase shell is often regarded as a simple utility to perform basic DDL and maintenance activities. However, it is in fact a powerful, interactive programming environment, primarily due to the JRuby engine under the covers. In this presentation, I'll describe its JRuby heritage and show some of the things that can be done with the "ird" (interactive ruby shell), as well as show how to exploit JRuby and Java integration via concrete working examples. In addition, I will demonstrate how the "shell" can be used in Hadoop streaming to quickly perform complex and large volume batch jobs.
JavaScript String:
The String object lets you work with a series of characters; it wraps Javascript's string primitive data type with a number of helper methods.
As JavaScript automatically converts between string primitives and String objects, you can call any of the helper methods of the String object on a string primitive.
JavaScript Arrays:
The Array object lets you store multiple values in a single variable. It stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.
Lithium: The Framework for People Who Hate FrameworksNate Abele
This is the presentation was given at ConFoo on March 11th by Nate Abele and Joël Perras, and is an introduction to the architectural problems with other frameworks that Lithium was designed to address, and how it addresses them. It also introduces programming paradigms like functional and aspect-oriented programming which address issues that OOP doesn't account for.
Finally, the talk provides a quick overview of the innovative and unparalleled features that Lithium provides, including the data layer, which supports both relational and non-relational databases.
Why async and functional programming in PHP7 suck and how to get overr it?Lucas Witold Adamus
This presentation describes basic issues related to functional programming with PHP and solution for most of problems served by the library called PhpSlang.
This talk is an overview of the history of the PHP language and major framework projects that have emerged in the last 5 years. It examines what we've learned in the development of these frameworks, how that education has been brought to bear in Lithium. Most of this talk ended up being me demoing and answering questions, so there's not a lot of content in the slides, sorry.
Slick: Bringing Scala’s Powerful Features to Your Database Access Rebecca Grenier
This talk will teach you how to use Slick in practice, based on our experience at EatingWell Media Group. Slick is a totally different (and better!) relational database mapping tool that brings Scala’s powerful features to your database interactions, namely: static-checking, compile-time safety, and compositionality.
Here at EatingWell, we have learned quite a bit about Slick over the past two years as we transitioned from a PHP website to Scala. I will share with you tips and tricks we have learned, as well as everything you need to get started using Slick in your Scala application.
I will begin with Slick fundamentals: how to get started making your connection, the types of databases it can access, how to actually create table objects and make queries to and from them. We will using these fundamentals to demonstrate the powerful features inherited from the Scala language itself: static-checking, compile-time safety, and compositionality. And throughout I will share plenty of tips that will help you in everything from getting started to connection pooling options and configuration for use at scale.
Building Lithium Apps (Like a Boss) was a workshop presented on the structure and philosophy of the Lithium framework and its applications, and how best to take advantage of them.

Studying geneva real estate prices using perl grammarsLaurent Dami
Geneva real estate transactions are published online, in free text. Perl regexes and grammars provide powerful tools to extract structured data from such free text and be able to get some trends and synthetic figures
An admin application for editing database, but with configurable features (grouping and ordering of tables and columns, hyperlink navigation between related records, etc.)
SQLite has this extensibility feature called "virtual tables", which is cool, except that it has to be written in C code. Now the same can be done in Perl code :-).
Gestion documentaire pour les tribunaux genevoisLaurent Dami

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
