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.
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.
This document provides an introduction to the Ruby programming language. It discusses Ruby's object-oriented nature, dynamic typing, syntax similarities to other languages like Java and C#, and the ease of learning Ruby. It also demonstrates simple Ruby code examples for arrays, hashes, classes, inheritance and modules. Testing practices like TDD (test-driven development) are emphasized. Popular Ruby web frameworks like Ruby on Rails, Sinatra and libraries like HAML and SASS are also introduced.
Most PHP developers focus on writing code. But creating Web applications is about much more than just wrting PHP. Take a step outside the PHP cocoon and into the big PHP ecosphere to find out how small code changes can make a world of difference on servers and network. This talk is an eye-opener for developers who spend over 80% of their time coding, debugging and testing.
Apple's Swift has achieved the top place in Stack Overflow's "Most Loved" list of programming languages in its 2015 Developer Survey.

This document discusses building web service clients with ActiveModel. It notes that ActiveModel is used for building forms and interacting with data internally within requests. It then discusses how to abstract complexity when working with web services and external APIs. It provides examples of using ActiveModel features like callbacks, dirty tracking, errors, serialization, and validations to build client-side models. It also discusses techniques for making parallel API requests using libraries like EventMachine and Typhoeus to improve performance. The goal is to build readable and maintainable client-side code that can scale with both complexity and team size.
This document discusses building web service clients with ActiveModel. It notes that ActiveModel provides attributes, callbacks, dirty tracking, errors handling, serialization and validations to make client code more readable and maintainable. It recommends using parallel connections and asynchronous libraries like EventMachine and Typhoeus for efficiency. Examples show defining requests in a threaded pool for concurrency.

Rails World 2023: Powerful Rails Features You Might Not Know
I gave a talk at Rails World 2023 in Amsterdam on Powerful Rails Features You Might Not Know.
If all you've got is a hammer, everything looks like a nail. In tech, there is a constant stream of new features being added every day. Keeping up with the latest Ruby on Rails functionality can help you and your team be far more productive than you might normally be.
In this talk, we walk through a bunch of lesser known or easy to miss features in Ruby on Rails that you can use to improve your skills.
The document discusses database queries and optimization. It begins with an example of a complex database query and explains how to detect problematic queries using tools like slow query log and pt-query-digest. It then discusses indexing strategies and when to use indexes. The document also describes a case study of a client's jobs search site that was experiencing high database load due to inefficient queries in a loop, and how batching the queries into a single query solved the problem.
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.
The document discusses tools for managing form data and validation. It introduces Data::Manager, which provides a way to manage incoming data and validation rules across multiple scopes or sections. Data::Manager uses Data::Verifier under the hood to validate data according to defined rules. It provides methods to verify data, check for errors, and retrieve validation results. The document emphasizes usability, reliability, and hiding complexity through a clean API.

Quality Patents: Patents That Stand the Test of Time
Is your patent a vanity piece of paper for your office wall? Or is it a reliable, defendable, assertable, property right? The difference is often quality.
Is your patent simply a transactional cost and a large pile of legal bills for your startup? Or is it a leverageable asset worthy of attracting precious investment dollars, worth its cost in multiples of valuation? The difference is often quality.
Is your patent application only good enough to get through the examination process? Or has it been crafted to stand the tests of time and varied audiences if you later need to assert that document against an infringer, find yourself litigating with it in an Article 3 Court at the hands of a judge and jury, God forbid, end up having to defend its validity at the PTAB, or even needing to use it to block pirated imports at the International Trade Commission? The difference is often quality.
Quality will be our focus for a good chunk of the remainder of this season. What goes into a quality patent, and where possible, how do you get it without breaking the bank?
** Episode Overview **
In this first episode of our quality series, Kristen Hansen and the panel discuss:
⦿ What do we mean when we say patent quality?
⦿ Why is patent quality important?
⦿ How to balance quality and budget
⦿ The importance of searching, continuations, and draftsperson domain expertise
⦿ Very practical tips, tricks, examples, and Kristen’s Musts for drafting quality applications

Quality Patents: Patents That Stand the Test of TimeAurora Consulting
Is your patent a vanity piece of paper for your office wall? Or is it a reliable, defendable, assertable, property right? The difference is often quality.
Is your patent simply a transactional cost and a large pile of legal bills for your startup? Or is it a leverageable asset worthy of attracting precious investment dollars, worth its cost in multiples of valuation? The difference is often quality.
Is your patent application only good enough to get through the examination process? Or has it been crafted to stand the tests of time and varied audiences if you later need to assert that document against an infringer, find yourself litigating with it in an Article 3 Court at the hands of a judge and jury, God forbid, end up having to defend its validity at the PTAB, or even needing to use it to block pirated imports at the International Trade Commission? The difference is often quality.
Quality will be our focus for a good chunk of the remainder of this season. What goes into a quality patent, and where possible, how do you get it without breaking the bank?
** Episode Overview **
In this first episode of our quality series, Kristen Hansen and the panel discuss:
⦿ What do we mean when we say patent quality?
⦿ Why is patent quality important?
⦿ How to balance quality and budget
⦿ The importance of searching, continuations, and draftsperson domain expertise
⦿ Very practical tips, tricks, examples, and Kristen’s Musts for drafting quality applications
