JavaScript - Programming Languages course yoavrubin
The document provides an overview of JavaScript, covering its dynamic and prototype-based nature, data types including objects and functions, and how functions work including closures and the different ways functions can be called. It discusses key JavaScript concepts like everything being treated as a boolean, prototypal inheritance, and how functions are first-class objects that can be passed around and defined within other functions.
The JavaScript programming language is a multi-paradigm language that is misunderstood due to its name, design errors in early implementations, and use in web browsers. It is a functional language that uses objects, prototypes, and closures. Values in JavaScript include numbers, strings, Booleans, objects, null, and undefined. All other values are objects.
The document discusses lambda expressions in Java. It defines a lambda expression as a concise representation of an anonymous function that can be passed around. Lambda expressions allow for passing functions as arguments or returning them. They make code shorter and cleaner compared to anonymous classes. Functional interfaces are required for lambda expressions, where a functional interface defines a single abstract method that lambda expressions can implement.
Rjb is a Ruby gem that allows Ruby code to interact with Java objects by wrapping them in Ruby classes, enabling Ruby applications to leverage existing Java libraries and solutions. It provides a simple API for loading Java classes and calling methods on Java objects from Ruby without requiring a full Java runtime like JRuby. The document discusses how to install, configure and use Rjb to integrate Java functionality into Ruby and Rails applications.
Matthias Noback presented on creating "naked bundles" in Symfony that do not rely on bundle conventions and can be reused outside of Symfony. He advocated extracting code from bundles into independent libraries with explicit dependencies instead of implicit ones. This would allow the code to be reused in other frameworks. He provided examples of creating controller classes without extending base classes, using dependency injection instead of service location, and mapping entities with XML instead of annotations. The goal is to remove unnecessary ties to the framework so code is truly decoupled and portable.
The document provides an overview of JavaScript programming. It discusses the history and components of JavaScript, including ECMAScript, the DOM, and BOM. It also covers JavaScript basics like syntax, data types, operators, and functions. Finally, it introduces object-oriented concepts in JavaScript like prototype-based programming and early vs. late binding.
The document discusses various coding best practices and conventions for writing good quality code, including naming conventions, formatting guidelines, and general programming practices. Some key points covered include using descriptive names, consistent indentation and spacing, single responsibility per method, error handling, and separating concerns between layers.
This presentation will give you a brief background to JavaScript, what it is and where it comes from. Then it will walk you through general pitfalls, best practices and more advanced topics such as object-orientation, scope and closures.
Mobile Software Engineering Crash Course - C02 Java PrimerMohammad Shaker
This document provides an introduction to the Java programming language. It discusses Java concepts like object-oriented programming, the Java Virtual Machine, primitive data types, variables, control flow, classes and objects, inheritance, interfaces, exceptions, collections, multithreading, design patterns, and more. It also includes code examples and references to Oracle's Java documentation for further reading.
The document provides an overview of the JavaScript programming language, including its history, key concepts, values, operators, statements, and objects. It discusses JavaScript's misunderstood nature due to its name, design errors in early implementations, and use in browsers. Some key points made include: JavaScript is a functional language; it uses prototypal inheritance instead of classes; all values are objects except for primitive values; and functions are first-class objects that can be assigned and passed around.
Virtual functions allow polymorphism by implementing a common interface in base and derived classes that can be called dynamically at runtime. They are declared with the virtual keyword in the base class and overridden with the same name and parameters in derived classes. Pure virtual functions are virtual functions without a body declared using =0, making a class abstract that cannot be instantiated until overridden in derived classes. Virtual destructors ensure the correct derived class destructor is called when deleting polymorphic objects through a base class pointer.
The Bundle system is one of the greatest and most powerful features of Symfony2. Bundles contain all the files related to a single feature of your application: controllers, entities, event listeners, form types, Twig templates, etc. But how much of that actually needs to be inside a bundle?
In this talk we’ll take a bundle, containing all those different types of classes, configuration files and templates, and strip it down to the bare necessities. And I promise that after moving many files out of the bundle, everything still works.
While looking for ways to move things out of the bundle, I will discuss some of the more advanced features of bundle design, like prepending configuration, compiler passes and Doctrine mapping drivers. We will end with a very lean bundle, surrounded by a few highly reusable, maximally decoupled libraries.

Here are some potential caveats with BDD style testing:
1. The framework can feel too "magical" if it uses too much metaprogramming under the hood. The implementation details should not be obscured.
2. Descriptions can become too vague if they only state intentions at a very high level without concrete examples. Tests as documentation only works if the descriptions are clear and specific.
3. There is a risk of duplication if contexts or examples are not properly organized and nested. Descriptions should aim to be DRY.
4. Performance overhead of the framework if it does a lot of runtime reflection or string manipulation. The framework should have a small performance footprint.
5. Tests become brittle
Constructors and destructors are special member functions in C++ that are used to initialize and cleanup objects. Constructors are called automatically when an object is created and are used to set initial values for object attributes. Destructors are called automatically when an object is destroyed and can perform cleanup tasks. There are different types of constructors like default, parameterized, and copy constructors. Constructors and destructors have the same name as the class but constructors don't have a return type while destructors are preceded by a tilde (~).

For example, it states that ActiveRecord connects classes to database tables for persistence, while ActionPack handles routing, controllers and views.
The slides for a lecture about the Ruby programming language. This language was given at FEUP, on a course called "Laboratories of Object-Oriented Programming".
The document provides guidelines for testing Rails applications. It recommends that any code change should be driven by a failed test. Tests should be close to the code being tested and focus on functionality rather than specific code. It discusses testing models, associations, named scopes, validations, controllers, views, helpers, emails, user interactions, Ajax requests, external sites, Rake tasks, file uploads, legacy applications, and more. The goal is to have tests that result in high-quality code through a test-first approach.

It discusses Ruby's origins and timeline, key differences from Java like duck typing and mixins, and how Ruby approaches concepts like classes, objects, and closures differently. The document aims to explain Ruby's philosophy and help Java programmers transition to Ruby's more dynamic style.
Ruby for Java Programmers provides an overview of the Ruby programming language for Java developers. Some key points:
- Ruby was created in 1993 and gained popularity with the Rails framework in the mid-2000s. It influences include Smalltalk and Lisp.
- Ruby is dynamically typed with duck typing. Classes are objects that can be modified. Everything is an object with message passing.
- Similarities to Java include garbage collection and use of a virtual machine. Differences include optional syntax, mixins instead of interfaces, and reopening of classes.
- Ruby focuses on solving problems concisely while Java focuses on reusable building blocks. Closures and metaprogramming allow more flexible programming in Ruby.
You've learned to program in Ruby, but now you want to start learning about how to move beyond the language basics and make use of some of the dynamic parts of the Ruby language. We'll cover that a bit here.
Ruby 2.0 introduced several new features including keyword arguments, lazy enumerators, module#prepend, and default UTF-8 encoding. Keyword arguments allow defining method parameters with a new syntax for named arguments. Lazy enumerators let huge or infinite arrays be handled by controlling execution flow on the right side of enumerations. Module#prepend inserts a module in front of a class's ancestor chain, opposite of include. The default encoding was changed to UTF-8 to support all characters.
Ruby is a dynamic, open source programming language that was created in 1993 by Yukihiro Matsumoto who wanted to ensure that programming is simple, practical and enjoyable. It combines object-oriented and imperative programming and provides automatic memory management. Some key aspects of Ruby include being dynamically typed, following the principle of least surprise, and being multi-paradigm supporting object-oriented, functional and imperative programming.
This document summarizes a presentation about the future of the Rake gem and domain-specific languages (DSLs) in Ruby.
The presentation discusses:
1. How Rake works as a Make-like program implemented in Ruby syntax with tasks and dependencies. Rake files use standard Ruby syntax.
2. Examples of common patterns for building internal DSLs in Ruby using class/module methods, method definition, implicit/explicit code blocks, and instance evaluation.
3. How popular Ruby gems like Rake, Bundler, and Thor use DSL techniques and inherit from each other to provide domain-specific interfaces.
How to discover the Ruby's defects with web applicationHiroshi SHIBATA
tDiary is a web diary (nikki) system written in Ruby. It was one of the earliest Ruby web applications. By using metaprogramming techniques like eval and class_eval extensively, and supporting many plugins via Ruby code, tDiary helped uncover bugs in Ruby over time as Ruby evolved. Some examples include bugs around the $SAFE security mechanism, encoding handling in Ruby 1.9, and issues with methods like require and expand_path. Even now, tDiary runs test suites against the latest Ruby trunk daily and has found new bugs. While tDiary itself may change as Ruby changes, it serves as an example of how long-running real-world Ruby applications can help improve the language over time
The document provides an overview of key Java concepts including classes, objects, variables, methods, encapsulation, inheritance, polymorphism, constructors, memory management, exceptions, I/O streams, threads, collections, serialization and more.

It discusses techniques like extracting logic from controllers into models, replacing long methods with method objects, using service objects to separate concerns, and implementing form objects to clean up forms. Examples are provided for each technique.
Defending Commoditization: Mapping Gameplays and Strategies to Stay Ahead in ...Cory Foy
One of the goals of agility is to be able to respond rapidly to market change. But do you feel prepared to wake up to a product announcement from Amazon disrupting your entire business? Would you know what steps to take?
Instead of being worried, we can get mapping! Wardley Mapping, coined by Simon Wardley, is a way of understanding markets and components in a way that allows us to visualize and anticipate change in markets - and develop strategies and gameplays for how we can respond to them.
This session uses several real-world cases of work with organizations to map their landscape and show the strategies and gameplays that allowed them to reshape where they were headed - and allow you to understand your organization’s market and how you can think about features and product direction.

Choosing Between Scrum and Kanban - TriAgile 2015Cory Foy
The document compares and contrasts the Scrum and Kanban frameworks. Scrum is a framework that utilizes roles, artifacts, and events like sprints, stand-ups, and planning. Kanban focuses on visualizing workflow, limiting work-in-process, measuring and managing flow, making policies explicit, and using models for continuous improvement. Both aim to provide structure, frequent feedback, and adapting processes through inspecting outcomes. However, Kanban emphasizes evolutionary change through techniques like limiting work-in-process while Scrum relies more on timeboxed sprints.
In the software development world, we spend a lot of our time coding, and very little practicing. In this presentation to the Triangle.rb group, Smashing Boxes CTO Cory Foy talks about a focused development practice called Code Katas - and how they can help you improve your hiring, your team, and your own programming abilities

In this talk from Triangle.rb, Cory Foy goes over basic language features of Ruby, along with some gotchas from David Black's "The Well Grounded Rubyist". We cover variables, classes, blocks, and other aspects.
Agile Roots: The Agile Mindset - Agility Across the OrganizationCory Foy
In this talk from Agile Roots 2014, Cory Foy talks about what is necessary for agility across the entire enterprise - regardless of whether you are using Agile, Lean, or Waterfall. Cory also covers the three principles and four value statements of agility.
The document discusses the idea that code "cries" when it is difficult to understand and modify. It suggests reframing "code smells" as issues where the code is trying to communicate something but is not being understood. The author argues that software becomes harder to work with over time because developers try to force their own designs rather than letting the code evolve naturally through an iterative process. Developers are encouraged to let go of preconceived designs and diagrams in order to build code in a more organic, timeless way.
In this talk from a Tampa 8th Light University, Senior Craftsman Cory Foy details the design patterns used in Rails, and shows their use and implementation while reference Fowler's PoEAA and Alexander's Timeless Way of Building
Many companies have created a proper noun titled "Agile". But that word doesn't exist as a proper noun. The goal isn't to achieve some mythical ethos of "Agile" but instead to have organizational agility. This presentation covers the principles of Organizational Agility and how to make your organization get to the goal of agility.
Getting Unstuck: Working with Legacy Code and DataCory Foy
From this presentation for the IASA in 2007, Cory covers common challenges in dealing with Legacy Code and Data, and some tools and techniques for handling them.
