Plmce2012 scaling pinterest
The document describes Pinterest's scaling efforts from 2010 to 2012. It started with a single server on Rackspace and grew to use Amazon Web Services with over 100 web servers and database shards on MySQL, Redis, Memcache and other technologies.

Introduction to Active Record at MySQL Conference 2007
Active Record is an object-relational mapping pattern that allows mapping database tables to object classes. It uses the principle of "convention over configuration" to minimize configuration work. The Active Record pattern is implemented in Ruby on Rails through the ActiveRecord library, which provides methods for CRUD operations and associations between models. It aims to make working with databases and ORM intuitive for developers.
Ruby on rails
Migrations allow you to define and manage changes to your database schema over time. The document discusses ActiveRecord migrations, which provide a way to iteratively improve the database schema by adding, removing, and changing tables and columns. It also covers generating and rolling back migrations, common migration methods like create_table and add_column, and using migrations to support models and testing.
Developing an Automated Testing Strategy
The document discusses different types of automated testing including unit tests, integration tests, acceptance tests, manual tests, security tests, load tests, and A/B tests. It emphasizes that testing strategy should be determined by a team based on factors like the application, available resources, risks, and constraints. An effective strategy balances automation with different testing types based on priority areas and what will cause the most damage if failed.
Introduction to Active Record - Silicon Valley Ruby Conference 2007
Active Record is an object-relational mapping (ORM) pattern that allows developers to interact with a database using objects rather than SQL queries. It establishes a direct association between classes and database tables, and between class objects and table rows. The key characteristics of Active Record include directly mapping classes to tables, objects to rows, and using finders and setters to encapsulate data access. The Ruby on Rails framework includes an implementation of Active Record to provide data modeling and database access functions.

Jooctrine - Doctrine ORM in Joomla!
This document discusses using the Doctrine ORM framework to improve object mapping in Joomla. It describes how Doctrine allows mapping between objects and database tables through associations like one-to-one, one-to-many, and many-to-many relationships. Using Doctrine's mapping features could help address Joomla's limitations with hierarchies, nested objects, and separating data structure from content models. The Jooctrine package provides an easy way to use Doctrine in Joomla extensions by handling configuration, models, and table prefixes. While Doctrine improves object mapping, fully replacing Joomla's core functionality could break many aspects that rely on its current design.

Not Just ORM: Powerful Hibernate ORM Features and Capabilities
DevNexus 2014
Hibernate has always revolved around data, ORM, and JPA. However, it’s much more than that. Hibernate has grown into a family of projects and capabilities, extending well beyond the traditional ORM/JPA space.
This talk will present powerful features provided both by Hibernate ORM, as well as third-party extensions. Some capabilities are brand new, while others are older-but-improved. Topics include multiple-tenancy, geographic data, auditing/versioning, sharding, OSGi, and integration with additional Hibernate projects. The talk will include live demonstrations.

- Rails was developed by 37signals to build their BaseCamp application. It uses convention over configuration and opinionated defaults to provide a productive environment for web development.
- The MVC pattern organizes a Rails app into models, views, and controllers. Models manage data, views display it, and controllers handle requests and coordinate between models and views.
- Rails makes data access very simple with ActiveRecord. Models map directly to database tables, and CRUD (create, read, update, delete) operations are straightforward.
- Features like the rails console and built-in

Artificial Intelligence for XMLDevelopment
In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.

Securing your Kubernetes cluster_ a step-by-step guide to success !
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
