Effective PHP. Part 1
This document discusses different approaches for creating objects in PHP, including using static factory methods instead of constructors, enforcing singletons, making classes non-instantiable, and using the builder pattern. For static factory methods, the pros are that they are clearer and avoid ambiguous constructor parameters, while the con is they are harder to chain for subclasses. Singletons are efficient but can introduce state issues. Making a class non-instantiable clearly communicates its usage. The builder pattern prevents malformed objects and provides a nice chained interface, but is more complex.

Clean code
"Even bad code can function. But if code isn't clean, it can bring a development organization to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn't have to be that way." In this knolx session, a few important topics for having clean code are covered. Basically the following topics - Meaningful name, Functions, Comments and Classes.
Dev Concepts: Functional Programming
What is "functional programming", "pure function", "functional language", "lambda function" and "higher-order function" and how these concepts work in modern programming?
Watch the video lesson from Svetlin Nakov and learn more at:

Some basic FP concepts
This document discusses functional programming concepts like pure functions, immutable data, and avoiding side effects. It notes that FP uses higher-order functions, function composition, and transformation of immutable data structures rather than mutable state and assignment. FP allows for easier reasoning about programs, safer concurrency, and avoids problems introduced by mutable state. The document also advocates for representing data simply without defining classes and encourages practicing FP to understand its benefits.
Test in action week 4
Here are a few key points about using PHPUnit for Selenium testing:
- PHPUnit provides a SeleniumTestCase class that allows you to write Selenium tests that extend it. This gives you access to Selenium commands like open(), type(), click(), assertTitle(), etc.
- You'll need to have Selenium Server and a supported browser (Firefox, Chrome, IE) installed to run the tests.
- Tests using SeleniumTestCase are more like integration/acceptance tests that simulate user interactions and verify page content rather than isolated unit tests.
- Common things to test include page titles, form submissions, link navigation, page content validation after actions.
- Selenium IDE can be used to record tests that can be exported to PHPUnit
PhpSpec: practical introduction
This document provides an introduction to using PhpSpec for test-driven development (TDD). It explains what TDD is, the benefits of TDD, and why PhpSpec is a good choice for TDD in PHP projects. It then walks through setting up a PhpSpec project, describing a sample Blog class, writing examples to test the Blog class, running the tests, refactoring code, and using PhpSpec matchers. The document concludes with tips on using PhpSpec to design object interactions and collaboration.
Functions in php
This document discusses functions in PHP. It explains that functions allow reusing code by defining reusable blocks of code that can be executed multiple times by calling the function. It provides examples of defining functions, passing parameters to functions, returning values from functions, and variable scope within functions. It also discusses including files in PHP to break programs into multiple files.
Test in action week 3
The document discusses various techniques for testing code such as stubs, mocks, and fakes. It explains that stubs provide canned answers to function calls during a test. Mocks verify that functions are called correctly. Fakes have working implementations but take shortcuts. The document also discusses challenges in testing like dependencies and non-deterministic objects. It advocates for techniques like dependency injection and inversion of control to make code more testable and avoid direct dependencies.
php 2 Function creating, calling, PHP built-in function
The document discusses PHP functions, including how to create and call custom functions, and examples of useful built-in PHP functions. It explains that functions allow reusable blocks of code and built-in functions are pre-made and do not need to be created. Examples are provided for creating functions that take parameters and return values, as well as calling functions. Common built-in functions are also described, such as trim(), explode(), implode(), and print_r() which operate on strings and arrays.
Object Oriented PHP - PART-2
This document discusses object oriented PHP concepts including classes, inheritance, overriding functions, error handling, and file uploads. It provides examples of creating a class with methods, instantiating objects, extending classes, overriding parent methods, and defining custom error handling functions. It also demonstrates how to upload files in PHP by handling the file on the server, checking for errors, and moving the file to a target directory.
Introduction to Python decorators
Python decorators allow functions to be replaced or wrapped at runtime. Decorators are functions that take a function as an argument and return a replacement function. Decorators provide a way to modify or extend the behavior of functions in a clean Pythonic way. Common uses of decorators include logging, timing, retrying functions, and implementing other cross-cutting concerns.
Functions in php
Functions allow programmers to reuse code and avoid repetition. They are defined by giving a name to a set of statements, which can then be called elsewhere in the program. Functions may take parameters, which are values supplied to the function that it can then use. For example, a shopping function could take a list as a parameter so that it can output instructions to buy the items on that list, with the list changing each time the function is called.
Basic constructs i
The document discusses basic constructs in the Go programming language including filenames, identifiers, keywords, functions, function formatting, parameters, comments, and references. Filenames can contain lowercase letters and underscores but no spaces or special characters. Identifiers are case-sensitive and begin with a letter or underscore followed by letters or digits. Go has 25 reserved keywords. Functions are declared with the func keyword followed by the name and parameters in parentheses. Functions must have a main function and braces enclose the body. Comments can be single line with // or multiline between /* and */.
Test in action week 2
This document discusses PHPUnit, a unit testing framework for PHP. It covers PHPUnit installation, writing test cases, assertions, fixtures, organizing tests, and best practices for test naming, structure and design including the F.I.R.S.T. principles. Key topics include using PHPUnit to test classes, methods and exceptions, leveraging data providers, fixtures for shared test setup/teardown, and keeping tests clean with single concepts per test.
Functional programing in Javascript (lite intro)
This document provides a light introduction to functional programming concepts in JavaScript. It discusses the history of FP which originated from lambda calculus in 1930 and was utilized in early languages like Lisp. Key FP concepts covered include first-class functions, higher-order functions, pure functions, immutability, function composition, currying/partial application, and recursive functions. It also contrasts the declarative FP style with imperative programming and outlines some pros and cons of the FP approach.
Arrays & functions in php
Functions are blocks of code that perform tasks and can be reused. Large projects require functions to organize code and avoid repetition. Functions accept input, process it, and return output. Functions can be built-in to PHP or user-defined. User-defined functions are created using the function keyword and can accept arguments passed by value or reference. Arrays allow storing multiple values and are indexed with keys and values. Arrays can be numerically or associatively indexed.
PHP Barcelona 2010 - Architecture and testability
This document discusses techniques for improving code testability and maintainability. It recommends:
1. Applying SOLID principles like the single responsibility principle and dependency injection to reduce coupling and improve cohesion.
2. Avoiding direct static method calls and singleton patterns in favor of dependency injection as it allows dependencies to be mocked/stubbed for testing.
3. Following the law of Demeter to avoid excessive coupling between classes.
4. Using factories instead of singletons to allow injecting fakes/mocks for testing. Testing first and listening to tests results in more maintainable code.

The why and how of moving to PHP 5.4/5.5
With PHP 5.5 out and many production environments still running 5.2 (or older), it's time to paint a clear picture on why everyone should move to 5.4 and 5.5 and how to get code ready for the latest version of PHP. In this talk, we'll migrate an old piece of code using some standard and some very non-standard tools and techniques.
The why and how of moving to php 5.4
With PHP 5.4 out and many production environments still running 5.2 (or older), it's time to paint a clear picture on why everyone should move to 5.3 and 5.4 and how to get code ready for the latest version of PHP. In this talk, we'll migrate an old piece of code using some standard and some very non-standard tools and techniques.
Python lecture 8
This document outlines key concepts in object-oriented programming including constructors, polymorphism, encapsulation, inheritance, and an introduction to Pygame. It discusses how constructors are called to initialize objects, how polymorphism allows the same method to work on different types, and how encapsulation hides unnecessary details from users. Inheritance and multiple inheritance are explained with examples of subclasses inheriting and overriding methods. Finally, installing and initializing Pygame is briefly covered along with an overview of the game loop structure.
Magic methods
This document summarizes magic methods in PHP that allow for custom object behavior. It discusses methods for stringification (__toString()), object lifecycle (__construct(), __destruct()), property overloading (__get(), __set(), etc.), method overloading (__call(), __callStatic()), serialization (__sleep(), __wakeup()), cloning (__clone(), __set_state()), and object invocation (__invoke()). Examples are provided for each method. Performance benchmarks at the end show that magic methods have negligible overhead compared to normal method calls.

Quality Assurance for PHP projects - ZendCon 2012
This document provides an overview of quality assurance for PHP projects. It discusses the importance of revision control, documentation, testing, and automation in QA. Revision control systems like SVN and Git are recommended for team development and tracking code versions. PHP Lint is introduced for syntax checking files from the command line. Documenting code with PHPDoc is suggested. Unit testing forms and models is demonstrated using PHPUnit. Validation, filtering, and sanitizing user input is important for protection against exploits. Overall the document promotes establishing strong quality practices like testing, revision control, and documentation for PHP projects.
Symfony2 - WebExpo 2010
The document introduces Symfony2, an open-source PHP web application framework. It discusses key components like the dependency injection container, routing, and an object-oriented approach to handling requests and responses. It presents Symfony2's implementation of the MVC pattern using bundles, controllers and templates.

A tale of scale & speed: How the US Navy is enabling software delivery from l...
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
