Perl provides many powerful features and modules that allow developers to customize and extend the language. Some popular modules include Moose for object-oriented programming, TryCatch for exception handling inspired by Perl 6, and P5.10 features that backport Perl 6 functionality. While useful, some features like autoboxing and state variables could introduce subtle bugs if misused. Overall, Perl's extensibility makes it a very flexible language that can be adapted to many different use cases.

Those are the slides from my presentation for our local C++ Cracow User Grup. This time I described what is empty base class optimisation, how it affects unique_ptr and also how can we simplify the code with C++20's new attribute: [[no_unique_address]].
Introduction to Swift programming language.Icalia Labs
?
Take a look to Swift, if you've been developing for iOS in Objective-C many things may look familiar, maybe just "upgraded". If you're a first timer diving into iOS development we strongly recommend you to understand first the basics of Cocoa.
Ruby was created in 1995 by Yukihiro Matsumoto who wanted a scripting language more powerful than Perl and more object-oriented than Python. It draws inspiration from Perl for its syntax, Smalltalk for its object model, and Lisp for its meta-programming capabilities. Ruby is an interpreted, object-oriented language with dynamic typing where everything is an object and supports features like classes, modules, blocks and iterators. The Ruby on Rails framework further popularized Ruby for web development.
The document describes methods added to the String prototype in JavaScript to provide useful string manipulation functions. Some of the methods described include String.strip() for removing whitespace, String.sub() and String.gsub() for replacing patterns in strings, and String.parseQuery() for parsing query strings. The methods perform tasks like checking for empty strings, extracting or evaluating scripts in strings, and replacing/searching patterns using regular expressions.
This document contains source code for an online quiz system created by Sushil Kumar Mishra of ECE-I. It includes classes for drawing lines and boxes, managing menus, and controlling quiz functions like adding, deleting, and modifying questions in different subject databases. The main menu allows users to play quizzes, add questions, edit questions, or quit. Playing a quiz displays questions one by one with a time limit to select the correct answer. Scores are tracked and displayed at the end.
Swift is a multi-paradigm programming language developed by Apple for iOS, macOS, watchOS, and tvOS. It was inspired by Objective-C, Rust, Haskell, Ruby, Python, C#, CLU, and other languages. The document discusses Swift's history, principles, syntax including variables, constants, data types, functions, closures, and control structures. It provides code examples and explanations of Swift's main features.
The document introduces building a parser in PHP by explaining reasons for common fears around parsing, showing examples of language grammars like BNF and EBNF, and demonstrating how to generate a parser in PHP using PEG parsing expressions to parse a sample query language across multiple versions, with the potential to optimize parsed queries.
This document discusses Brick, a Perl module for validating data against business rules. Brick allows separating validation logic from code by defining rules as closures. Rules can be composed together to validate complex relationships. Validation results are returned as objects containing labels, methods, success indicators, and any errors, making issues easy to identify. The document provides examples of defining validation profiles and routines with Brick and using the results.
A Few Interesting Things in Apple's Swift Programming LanguageSmartLogic
?
The document discusses several interesting features of the Swift programming language, including type inference, mutability, optionals, named parameters, enumerations, switch statements, closures, and generics. Type inference allows variable types to be inferred from values rather than explicitly declared. Optionals handle the absence of values and can be conditionally unwrapped. Closures provide block syntax similar to Objective-C but with additional optional syntax. Generics allow structures to work with different types rather than a single type.

(ThoughtWorks Away Day 2009) one or two things you may not know about typesys...Phil Cal?ado
?
Type systems are not just syntax checkers, but are intended to prevent execution errors by catching type errors. Static typing catches errors at compile-time rather than run-time, as demonstrated by examples in Ruby and C#. While static typing can seem bureaucratic in some languages, it enables type inference and other "smart" features in languages like Haskell. Both static and dynamic typing are flexible depending on the language, as dynamic languages allow for eval and meta-programming while static languages have reflection and templates. Overall, typing influences language design and tools but flexible features depend more on the language's meta-model, while static languages can feel bureaucratic due to historical reasons rather than limitations of the typing model.

A wise hacker said: Some people, when confronted with a problem, think ¡°I know, I¡¯ll use regular expressions.¡± Now they have two problems.
Regular expressions are a powerful tool in our hands and a first class citizen in ruby so it is tempting to overuse them. But knowing them and using them properly is a fundamental asset of every developer.
We¡¯ll see hands-on examples of proper Reg Exps usage in ruby code, we¡¯ll also look at bad and ugly cases and learn how to approach writing, testing and debugging regular expressions.

It provides examples of functions like DateAdd(), DateDiff(), DatePart(), DateSerial(), FormatDateTime(), IsDate(), Day(), Month(), Year(), MonthName(), WeekDay(), Now(), Hour(), Minute(), Second(), Time(), Timer(), and TimeSerial(). These functions allow manipulating dates and times, extracting date/time parts, formatting dates, comparing dates, and converting between number formats in VBScript programs. Syntax and examples are given for each function to demonstrate their usage.
This document discusses lenses and their uses. Lenses allow both getting and setting values in an object. They are defined as functions that take a function and object as arguments and return a modified object. Lenses can be composed to access nested values. Examples show defining lenses to access properties, modify values using lenses, and compose lenses to access nested properties.
This document provides an overview of classes in C++. It begins with definitions and concepts related to classes, such as encapsulation and user-defined types. It then provides examples of declaring and defining a simple Time class with attributes like hours, minutes, seconds and methods to set, get, print and change the time. The document also discusses class members, access specifiers, constructors, pointers and references to class objects, and getter and setter methods. It concludes with brief mentions of utility functions, separating interface from implementation, and organizing classes across header and source files.
The document provides information about work, energy, and forces. It defines work as force times distance moved in the direction of the force. It discusses calculating work done by gases expanding and compressing. It also defines kinetic and potential energy, and discusses energy conversion and conservation. Hooke's law and concepts like strain energy and Young's modulus are explained. Finally, the document covers topics like power, moments of force, couples, and principles of equilibrium.

SQLite is a file-based database engine that stores databases in files on disk. It supports databases up to 2TB in size and can be easily portable across platforms. SQLite is completely typeless, meaning fields do not need to be associated with a specific type. SQL commands are used to interact with SQLite databases from PHP. Queries return result objects that can be fetched and processed row by row or all at once to retrieve the full result set.
1. The document discusses building web interfaces using Ruby on Rails. It covers useful Rails view helper techniques, plugins for adding helper and unobtrusive JavaScript functionality, and implementing common UI design patterns.
2. The handicraft_helper plugin allows building complex HTML structures more easily using a composite pattern. The handicraft_ujs plugin replaces Rails' default Ajax functionality with an unobtrusive JavaScript approach using jQuery.
3. The presentation demonstrates helper techniques, the two plugins, and implementing UI patterns like inline editing and sortable lists.
The document provides an overview of JavaScript and the Document Object Model (DOM). It introduces JavaScript as a scripting language used to add interactivity and dynamic behavior to web pages. It describes how JavaScript can be implemented in HTML using <script> tags in the head or body, or externally in .js files. The document then covers JavaScript syntax including data types, operators, conditional statements, loops, functions. It also discusses the DOM and how JavaScript can manipulate HTML elements and attributes.
jQuery is a JavaScript library that makes it easier to select elements, handle events, perform animations, and develop Ajax applications. It works by separating behavior from HTML structure through selectors, events, and methods. The $ function is an alias for jQuery and is used to select elements and execute functions on page load or other events. jQuery can be included in a page and used to simplify DOM manipulation, event handling, animation, and AJAX interactions.
This document provides an introduction to MERB (Modular, Elegant Resource-Based) and discusses several key concepts related to MERB including background processes, web services, embedded components, distributed applications, and the Rack middleware framework. The document is written in an informal tone and touches on many different topics at a high-level without going into detail on any single topic.
This document provides an introduction to the Ruby on Rails web framework. Some key points:
- Rails is a model-view-controller framework for building database-backed web applications using the Ruby programming language. It emphasizes conventions over configuration for rapid development.
- Rails was created by David Heinemeier Hansson in 2004 and saw major growth and adoption from 2005-2006. It provides features like object-relational mapping and support for Ajax.
- Comparisons between Rails and other technologies like Java show much higher growth and smaller project sizes for Rails applications. Rails allows developers to be more productive and focus on business logic rather than infrastructure code.
The document discusses Rack, a modular web server interface for Ruby that allows web applications and frameworks to be written as middleware stacks. It covers topics like Rack applications as middleware, common Rack middleware components, building applications with Rack and middleware, and integrating Rack middleware with frameworks like Rails.
The document provides an overview of Dynamic HTML (DHTML) and its core technologies: HTML, CSS, JavaScript, and the DOM. It explains that DHTML allows dynamic and interactive web pages by combining these technologies. JavaScript is described as the scripting language that defines dynamic behavior, handling events and user interactions to manipulate the DOM. The document gives examples of common JavaScript functions, syntax elements, and how to incorporate JavaScript code into web pages.
The document discusses HTML5 features such as new structural elements, form types, media elements, and JavaScript APIs for canvas, local storage, web databases, web workers, websockets, geolocation, and offline web applications. It also covers tools and techniques for building mobile web apps, including jQtouch for iPhone styling, feature detection over browser detection, and PhoneGap for compiling HTML5 apps to native mobile apps. While HTML5 provides many capabilities for mobile, native apps still have advantages in accessing device hardware and approval processes.

We have successfully established our development process for Drupal custom modules, including automated testing using PHPUnit, all managed through our own GitLab CI/CD pipeline. This setup mirrors the automated testing process used by Drupal.org, which was our goal to emulate.
Building on this success, we have taken the next step by learning Behavior-Driven Development (BDD) using Behat. This approach allows us to automate the execution of acceptance tests for our Cloud Orchestration modules. Our upcoming session will provide a thorough explanation of the practical application of Behat, demonstrating how to effectively use this tool to write and execute comprehensive test scenarios.
In this session, we will cover:
1. Introduction to Behavior-Driven Development (BDD):
- Understanding the principles of BDD and its advantages in the software development lifecycle.
- How BDD aligns with agile methodologies and enhances collaboration between developers, testers, and stakeholders.
2. Overview of Behat:
- Introduction to Behat as a testing framework for BDD.
- Key features of Behat and its integration with other tools and platforms.
3. Automating Acceptance Tests:
- Running Behat tests in our GitLab CI/CD pipeline.
- Techniques for ensuring that automated tests are reliable and maintainable.
- Strategies for continuous improvement and scaling the test suite.
4. Template-Based Test Scenario Reusability:
- How to create reusable test scenario templates in Behat.
- Methods for parameterizing test scenarios to enhance reusability and reduce redundancy.
- Practical examples of how to implement and manage these templates within your testing framework.
By the end of the session, attendees will have a comprehensive understanding of how to leverage Behat for BDD in their own projects, particularly within the context of Drupal and cloud orchestration. They will gain practical knowledge on writing and running automated acceptance tests, ultimately enhancing the quality and efficiency of their development processes.
