Why I will never write JavaScript ever again*The Wolff
Wolff explains why he prefers CoffeeScript over JavaScript. CoffeeScript removes unnecessary syntax like curly braces and wrappers, handles scoping and binding functions automatically, and compiles to clean JavaScript. This allows humans to write code in a more readable way and focuses on problem solving rather than syntax. CoffeeScript produces efficient JavaScript behind the scenes so programmers can spend less time on low-level details and more on organization, cleanliness, and having fun building things.
This document summarizes RubyMotion, a tool that allows developers to create iOS and OS X applications using Ruby instead of Objective-C. It discusses RubyMine, an IDE for RubyMotion development, and various Ruby libraries like BubbleWrap, Teacup, and Joybox that provide wrappers and helpers for common tasks like making HTTP requests, building user interfaces, and using the Cocos2D and Box2D frameworks in a RubyMotion app. It also briefly mentions some popular apps and books related to RubyMotion development.
This document discusses code quality tools for Ruby code and how RubyMine can help. It introduces static and runtime tools for finding code smells, metrics for measuring qualities like duplication, and testing and coverage tools. RubyMine integrates many of these tools and performs on-the-fly code inspections to help improve code quality. The document encourages attendees to try RubyMine's code quality features themselves.
Slides from my talk for the GenevaWeb meetup on 17. September 2018. The presentation introduced the CSS Grid Layout Module, and gave an overview of how the different parts of it fit together.
Core Data doesn't have to be hard. Step by step, learn how to use Core Data in code, creating models and relationships. Loading data and efficiently displaying that data.
The document discusses Sass, a CSS extension language that adds powerful features like variables, nested rules, mixins, functions and more. It outlines problems with traditional CSS like repetition, maintenance issues and lack of abstraction capabilities. Sass aims to solve these through its additional features that allow for more modular, reusable and maintainable stylesheets. It also introduces Compass, a Sass extension framework and library, and discusses best practices like organization, sprites and separation of concerns.
This document discusses code smells and tools for analyzing Ruby code quality. It notes that most code changes involve modifying existing code. It then describes several static code analysis tools like Reek, Flog, and Roodi that inspect code without running it, as well as runtime tools like RSpec and SimpleCov that execute code. Finally, it emphasizes the importance of both static analysis and testing, and recommends trying the RubyMine IDE for refactoring code.

Becoming a more productive Rails DeveloperJohn McCaffrey
A presentation by John McCaffrey of RailsPerformance.com on how to manage technical information, ask technical questions, expand Ruby and Rails knowledge, and work on interesting side projects for open source, non-profits or as a freelancer
Ruby is an object-oriented scripting language designed by Yukihiro Matsumoto to be more powerful than Perl and more object-oriented than Python. It focuses on making programming easy for humans rather than optimizing for machines. Ruby follows common naming conventions like CamelCase for classes/modules, ALLCAPITAL for constants, and underscores for method/variable names. Everything in Ruby is an object, including fundamental types like strings, arrays, ranges, and hashes. The language uses classes to define objects and supports concepts like blocks, flow control with conditionals and loops, and exceptions. Key resources for learning Ruby include the Programming Ruby book, the Ruby API documentation, TryRuby tutorials, and the Ruby Warrior game.

LeanStartup:Research is cheaper than developmentJohn McCaffrey
The document discusses the importance of conducting thorough research before beginning development on a new project. It argues that research is cheaper than development and can help define the problem, understand existing terminology and solutions, identify target customers, and find market trends. Both primary and secondary research methods are covered, including interviews, online searches, social bookmarking, and polling forums. The presentation provides tips for creating a project profile and researching problems, customers, influencers, and monitoring competitors. It emphasizes gathering useful data and testing hypotheses before taking action.
How to Build a Bespoke Page Builder in WordPressGerald Glynn
This document discusses building a bespoke page builder for WordPress. It covers using Advanced Custom Fields to create custom fields that store metadata which can then be used to dynamically generate page content. The key benefits are that it allows marketing and content teams to create customized page designs and flows without needing coding skills, while reducing the back-and-forth between developers and other teams. Potential pitfalls discussed include performance optimizations and how to best structure fields and templates.
This document discusses the history and future of JavaScript, including major versions like ES3, ES5, and the upcoming ES6. It also covers commonly used JavaScript libraries and frameworks like jQuery, AngularJS, Backbone, EmberJS, and React. Additionally, it mentions server-side JavaScript with Node.js, tools like Grunt and Gulp, JavaScript dialects like TypeScript and CoffeeScript, and new features coming in ES6 like classes, arrow functions, and promises.
This document discusses HTML, CSS, and JavaScript and their roles in web browsers. HTML defines content, CSS handles styling and layout, and JavaScript controls behavior and interactivity. It also mentions variables, arrays, functions, JavaScript libraries, and some of the challenges of arranging HTML elements.
The document discusses REST (Representational State Transfer) and how it relates to building applications with Ruby on Rails. It shows an example of modeling book resources and actions like GET, POST, PUT, DELETE in a Rails application. REST uses standard HTTP verbs and URLs to manipulate resources, and Rails' resource routing generates routes for the default RESTful actions on a resource like books. The document provides examples of defining routes for books and generating a route table with corresponding controller actions.
Lose Your Head! Re-imagining WordPress's Role in Content PresentationJeremy Ward
Since the introduction of the REST API, developers have been seeking ways to leverage the benefits of WordPress for content creation, while offering new options for presenting that information on the client side. Native mobile apps, JavaScript front-ends, static sites – the possibilities are endless.
Let’s take a closer look at the benefits and limitations of going “headless” with WordPress, find out what the hype is about, and determine whether this approach is something that could benefit you or your clients.
Ruby Kansai #35 About RubyKaigi2009 ujihisaujihisa
- Yehuda Katz gave a talk titled "From Rails to Rack: Making Rails 3 a Better Ruby Citizen" where he discussed how Rails 3 has moved away from being a full-stack framework by extracting common components like Rack into separate gems making Rails a better Ruby citizen.
- Aaron Patterson discussed how the Nokogiri library can be used to parse HTML and XML documents in a fast and flexible manner.
- ujihisa gave a talk titled "Vim for Rubyists" where he discussed how Vim can be a powerful tool for Ruby development by taking advantage of features like syntax highlighting, code completion, and running tests directly from within Vim.

The Transparent Web: Bridging the Chasm in Web Developmenttwopoint718
The document discusses the concept of a "transparent web" where the distinction between client-side and server-side code is minimized. It provides examples using Opa and Ur/Web programming languages to demonstrate "Hello World" programs that can compile and run code on both the client and server without needing to manage separate codebases. The document argues this approach can help address common problems with web applications like security, managing multiple languages, and taking on system administration tasks. It acknowledges some may be hesitant but argues the benefits of increased productivity and reduced errors will lead to this approach becoming standard.
The document summarizes a workshop on Drupal and Ruby on Rails that was held on September 10-11, 2011 at DDIT, Nadiad. It provides overviews of Ruby and Ruby on Rails, their uses, strengths, directory structures, MVC architecture, and supporting technologies like HTML5, CoffeeScript, Sass/SCSS, and CSS3. It also lists some major companies that use Ruby on Rails for their web applications and products.
The code will print false, because paid = true assigns a local variable rather than setting the instance variable @paid. To fix it, use self.paid = true.
The document introduces Ruby on Rails and provides an overview of its features and benefits. It summarizes the speaker's experience with web development over time, introduces MVC and ORM concepts, and demonstrates Rails through a live coding example. Key advantages of Rails highlighted include its convention over configuration approach, use of Ruby as a dynamic scripting language, and ability to rapidly develop database-backed web applications.
This document provides an overview of key concepts in Ruby on Rails including:
- Rails uses the MVC pattern with models, views, controllers, and follows conventions like RESTful design and resource-oriented URLs.
- ActiveRecord is the ORM that connects database tables to model classes for easy data access. Migrations help manage the database schema.
- Views use ERB templates to display data and helpers to DRY up common HTML patterns. Layouts wrap views in a consistent layout.
- Controllers handle HTTP requests and route them to actions that retrieve data from models and pass it to views to display. Flashes store temporary session data.
- Rake tasks help automate common
This document discusses technologies for creating and maintaining web applications. It covers Ruby and the Rails framework. Ruby is designed to be programmer-focused rather than machine-focused, helping create dynamic and self-explained code. Rails enables quickly building web servers through conventions, reuse, single responsibility principles, and features that provide quick setup, deployment, and built-in scalability. The document also discusses front-end architecture with client-side logic, and Rails features for development, deployment, databases, assets, and multi-environment configuration.

Overview
Some people consider responsive design to be cross-platform, and responsive design to be resizing for containers. However, this misses the distinction of fluid design & often leads to slow and bad programmatic implementations. This talk will cover the distinction and provide pointers on how to implement responsive apps that are also performant.
Attendees should understand a differing view on how to build cross-platform apps, and the difference between fluid & responsive design.
Target Audience
Programmers, designers & cssers who think a single page with lots of media queries is a good idea.

Ruby on Rails is a web application framework that is designed to make programming web applications easier and more enjoyable. It includes features like an object-relational mapper called Active Record that allows database rows to be represented as objects, conventions that reduce configuration, and support for test-driven development. Rails is built on Ruby, an interpreted object-oriented programming language, and aims to be programmer friendly and allow powerful applications to be built quickly. Several experts praise Rails for lowering the barriers to entry for programming and being a well-thought-out framework.

Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
