-- Form Extensions
-- Data Transformers
-- Form Tests
This document discusses layouts in presentations. It describes layout as defining the visual structure of the UI as a tree hierarchy of page blocks. It covers block types, layout builders, themes, contexts, data providers, and other topics for working with layouts.
This document discusses decoupled or headless Drupal architectures. It defines decoupled Drupal as allowing other technologies to render the front-end experience, while Drupal serves as the content provider. Real-world examples are provided to illustrate the request-response pattern. Normal Drupal architecture is contrasted with headless architectures, where Drupal outputs JSON data via REST APIs rather than HTML. Headless Drupal can then connect to multiple front-end clients and frameworks. Drupal 7 and 8 options for decoupling are examined, as well as a case study of using Drupal 7 as a content provider with a Symfony front-end.
The Render API in Drupal 7 provides a system for rendering structured data arrays into output like HTML. It is an improved version of the Forms API rendering that uses drupal_render() to generate nearly all page output from render arrays. Render arrays allow elements and pages to be assembled, altered, and cached flexibly through a consistent rendering process. Themes can also interact with render arrays to style output without modifying module code.
This document discusses the multilingual capabilities of Drupal 8 for building a customized checkout system. It describes how to make custom entities, forms, blocks and menus translatable by declaring them as such and importing translations using .po files. It also covers getting current language codes and names, translating configuration settings, and using contrib modules like Language Icon for language switching. The customized checkout system allows translating custom checkout entities, forms and fields into multiple EU languages.
This document provides an overview of HTML and XHTML. It describes that HTML is the markup language used to create web pages, consisting of elements with tags. It discusses HTML tags, elements, attributes and comments. It then explains that XHTML was developed as a reformulation of HTML in XML format for increased extensibility and interoperability. The document outlines the standard structure for XHTML documents, including the XML declaration, DOCTYPE declaration and namespaces.
This document provides an introduction to HTML (Hypertext Markup Language) and basic HTML tags. It explains that HTML documents describe web pages using tags surrounded by angle brackets. An HTML file must have a .htm or .html extension. It then discusses how the web works using a client/server model and HTTP protocol and defines a web page as a text file containing HTML markup tags that provide structure and formatting. The document gives a simple example HTML code to create a heading and shows how tags normally come in pairs. It also provides an overview of common HTML tags.
Slim is a template language that provides a minimal syntax for generating HTML and XML. It aims to be faster and cleaner than other templating languages like HAML and ERB. The presentation covers what Slim is, its syntax features, performance comparisons to other languages, and includes a demo.

Cloud Native CI/CD with Spring Cloud PipelinesLars Rosenquist
Spring, Spring Boot and Spring Cloud are tools that allow developers to speed up the creation of new business features. But a new feature is only useful if it's in production. Companies spend a lot of time and resources on building their own deployment pipelines using a plethora of technologies. Spring Cloud Pipelines provides an opinionated way for getting your features to production in a fast, reliable, reproducible and fully automated way.
Cloud Native CI/CD with Spring Cloud PipelinesLars Rosenquist
The document discusses Spring Cloud Pipelines, which provides an opinionated continuous integration and continuous delivery (CI/CD) pipeline for deploying applications. It outlines the challenges of traditional CI/CD approaches and how Spring Cloud Pipelines addresses them by standardizing and automating the pipeline. The key aspects covered include:
- The anatomy of an opinionated pipeline, including environments like build, test, stage, and production.
- How the pipeline incorporates different types of automated testing at each stage, from unit to integration to smoke tests.
- The typical steps in the pipeline like building, testing API compatibility, deploying to environments, smoke testing, rolling back if needed, and deploying to production.
The document discusses agile evolutionary design principles and SOLID principles. It introduces the typical evolution of systems over time from an initial beautiful design to a legacy system as features are added and changed. It then covers agile design processes and principles like XP practices. The main part explains each SOLID principle - single responsibility, open/closed, Liskov substitution, interface segregation and dependency inversion principles. For each, it provides a definition, design smells when violated, and examples of better designs that follow the principle.

So You Just Inherited a $Legacy Application...Joe Ferguson
You were just handed the keys to a new repo. Your first glance over the code base causes the fearful "LEGACY" word to ring in your head. HAVE NO FEAR! I'll share the techniques I've learned after working on several legacy codebases to help update that old code to the current PHP generation. We'll cover triaging the old code base, writing tests to make sure you don't break anything, and how to modernize your old code base!

Most dev teams have a very simple conception of software architecture. They start with a database, a user interface, and add layers of (DRY) mess between the two. Then they have a performance problem so they add memcache and mongodb (Now we're webscale!).
Months or years later, releasing new features in production gets harder and riskier: it's time for a rewrite. Let's use AnguNodeMvcDoop to solve all our maintainability issues! And the cycle starts over...
In this talk we'll see that software architecture is not defined by the technologies you use but by the high level principles you set. We'll see what really matters to make your information system maintainable and how to get there progressively!
This document discusses various JavaScript design patterns. It begins by defining design patterns as recurring solutions to common software design problems. It then covers types of patterns such as creational, structural, and behavioral. Specific patterns like module, revealing module, singleton, prototype, factory, facade, and observer are demonstrated. Benefits include reusability, communication, and encapsulation. Drawbacks include additional complexity and difficulty testing in some cases. Examples are provided to illustrate usage of the patterns.
The document discusses design patterns and provides an example of implementing the Observer pattern. It begins with an overview of design patterns, their origins and classification. It then discusses the Observer pattern specifically and provides a weather monitoring system example. In the example, different display elements need to be notified when weather data changes. Initially, the WeatherData class directly updates each display, violating open-closed and single responsibility principles. The example is then refactored to use the Observer pattern by having displays implement an Observer interface and register with the WeatherData subject.
An intuitive guide to combining free monad and free applicativeCameron Joannidis
The usage of Free Monads is becoming more well understood, however the lesser known Free Applicative is still somewhat of a mystery to the average functional programmer. In this talk I will explain how you can combine the power of both these constructs in an intuitive and visual manner. You will learn the motivations for using Free Structures in the first place, how we can build up a complex domain, how we can introduce parallelism into our domain and a bunch of other practical tips for designing programs with these structures. This will also give you a deeper understanding of what libraries like Freestyle are doing under the hood and why it is so powerful.
Are you sick of Merge Hell? Do your feature branches go rogue? Do you spend more time fiddling with your Version Control System than doing actual development work? Then Trunk Based Development might be for you. Facebook does it. Google does it. Instead of messing with multiple branches, just use your master branch. Always. In addition to giving you an overview about how Trunk Based Development works, where it shines and where the pitfalls are, this talk will also cover the necessary techniques to succeed with it, such as Branch By abstraction, Feature Toggles and backwards compatible Database Migrations.
This document provides an overview of intermediate GIT concepts including merge conflicts, tags, stashes, pull requests, workflows, and hooks. It defines merge conflicts as occurring when multiple developers have edited the same part of a codebase. It describes how tags are used for versioning and stashes for temporarily storing code. Pull requests are discussed as a way to get code reviews and collaborate. Common workflows like forking and GIT flow are presented. Finally, hooks are defined as scripts that run automatically during GIT interactions and examples of client-side and server-side hooks are given.

Twig is the most powerful templating engine in the PHP world that enables us to create highly complex projects with hundreds of multi-level extended templates, thousands of blocks, functions, filters, tests, and macros. It also offers a sandbox, a unique but not a widely used feature that is creating secure user-editable templates. In addition, there are a number of handy built-in and external debugging tools available in the Twig ecosystem to simplify the day-to-day work process for a Twig designer.
In this presentation, I will talk about how extensively we use Twig in a complex open-source e-commerce project.
Effectively Reuse the Code Between PHP ProjectsAndrew Yatsenko
The new project has come, and you need to reuse several libraries from the old one? Or maybe you have added a new microservice and need to reuse a couple of packages from other microservices?
In this report, I'm reviewing methods for reusing code between applications that we have experienced on our projects for several years. I show how to avoid copying the packages, while not spending additional resources on the publication of individual packages.
The talk is about practical usage of git submodules, composer public, private, VCS and "path" repositories, and git subtree splitter; benefits, and cons of each method, and how we used them in practice for multiple projects.
Performance profiling and testing of symfony application 2Andrew Yatsenko
This document discusses performance profiling and testing of a Symfony application. It recommends using tools like the Symfony profiler toolbar, Blackfire, and logging to measure metrics like SQL query times, external API calls, memory usage, and more. Capturing these metrics during testing and in production helps identify bottlenecks in the code related to performance. The goal is to measure code quality from a performance perspective and ensure the application meets requirements for speed and responsiveness.
This presentation discusses data cache management in PHP. It covers cache concepts like unique cache keys and lifetimes. It discusses different cache strategies including frontend caching, backend caching, and custom data caching. It also covers the Doctrine cache component, PSR-6 caching standard, and Symfony cache component. Additional cache features like tags and hierarchies are described. Common pitfalls of caching are also highlighted.
The document is a presentation about Doctrine internals and the UnitOfWork pattern. It discusses how the UnitOfWork tracks object changes, uses an identity map to avoid extra database queries, and allows committing changes transactionally to the database. It also describes how the EntityManager acts as a decorator for the UnitOfWork and other Doctrine components, and walks through the full process when fetching, updating, and flushing entities.

Gas agency management system project report.pdfKamal Acharya
The project entitled "Gas Agency" is done to make the manual process easier by making it a computerized system for billing and maintaining stock. The Gas Agencies get the order request through phone calls or by personal from their customers and deliver the gas cylinders to their address based on their demand and previous delivery date. This process is made computerized and the customer's name, address and stock details are stored in a database. Based on this the billing for a customer is made simple and easier, since a customer order for gas can be accepted only after completing a certain period from the previous delivery. This can be calculated and billed easily through this. There are two types of delivery like domestic purpose use delivery and commercial purpose use delivery. The bill rate and capacity differs for both. This can be easily maintained and charged accordingly.

Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.
Mechatronics is a multidisciplinary field that refers to the skill sets needed in the contemporary, advanced automated manufacturing industry. At the intersection of mechanics, electronics, and computing, mechatronics specialists create simpler, smarter systems. Mechatronics is an essential foundation for the expected growth in automation and manufacturing.
Mechatronics deals with robotics, control systems, and electro-mechanical systems.

Electric propulsion technology is widely used in many kinds of vehicles in recent years, and aircrafts are no exception. Technically, UAVs are electrically propelled but tend to produce a significant amount of noise and vibrations. Ion propulsion technology for drones is a potential solution to this problem. Ion propulsion technology is proven to be feasible in the earth’s atmosphere. The study presented in this article shows the design of EHD thrusters and power supply for ion propulsion drones along with performance optimization of high-voltage power supply for endurance in earth’s atmosphere.

When applications should be extensible?
When you write:
● a lot of similar apps
● requirements change a lot
● a lot of features in one app
● open-source
5. Presentation title here
provide for change (enhancements)
● while minimizing impact to existing system
functions.
● is a design principle where the
implementation takes future growth into
consideration.
● extensions can be through the addition of
new functionality or through modification
of existing functionality
Extensibility
15. Presentation title here
Modular design
Separating the functionality of a program into
independent, interchangeable modules,
such that each contains everything
necessary to execute only one aspect of the
desired functionality.

What Symfony offers?
Service container
● Overriding classes of services with the
same dependencies with parameters
27. Presentation title here
What Symfony offers?
Service container
● Overriding services in compiler passes with
the same interface or by extending the
original one in Compiler Passes
31. Presentation title here
What Symfony offers?
You still can provide extension.
There is no out of the box solution, because
you don’t need it.
You can check examples:
● Twig
● Form
32. Presentation title here
Conclusion
● Extensions helps you to make addition and
modification of your application while
minimizing impact to existing functionality.
35. Presentation title here
P.S.
Ideal OO code not the answer, because of
performance.
You can scale your infrastructure, because it's
cheaper than development in some situations
but usually not for a long time.
