REST is an alternate and simpler approach for implementing WebServices. It is based on the HTTP protocol and hence leverages a lot of existing infrastructures. It uses an uniform interface thus making it easy to build client applications. In this session we will look at the fundamental concepts behind REST (Resource, URI, Stateless Conversation ..) and how to apply it in the context of a real applcation. We will also discuss the pros & cons of RESTful vs Soap based webservices. We will discuss the design of RESTful application and then look at how to implement it using Spring MVC.

Alex Demchenko

Александр Демченко, CEO Lazy Ants выступил на конференции CODEiD – PHP Odessa Conf #4 с темой «Graphql + Symfony». • Что такое GraphQL на пальцах для PHP-разработчика. • Почему GraphQL это глобальный скачек в написании API. • Почему такие монстры как Facebook, GitHub активно используют GraphQL для своих API. «Мы рассмотрим основные преимущества использования GraphQL для вашего проекта, как создать свое GraphQL API с помощью Symfony framework и набором доступных библиотек.» CODEiD – это всеукраинское сообщество PHP-разработчиков. Наша цель — создать сильное сообщество всех, кто увлечен PHP-разработкой, и принимать в нашем уютном приморском городе коллег со всей Украины и мира.

Are you depressed? We perform this come-to-me love spell that works instantly with the aim of bringing back the victim to the person performing the magic. Have you lost your lover? We perform this come-to-me love spell that works instantly with the aim of bringing back the victim to the person performing the magic. Have you lost your lover? Do u need to solve any relationship problem? Contact the powerful spells caster chief kule with love spells that work overnight and love spells that really work. Have you found yourself infatuated with a special someone you think could be the one? Are you looking for a spell to provide them with a nudge in the right direction? Or maybe the spell you cast didn’t achieve the results you were hoping for? Whether you’re new or versed in the ways of spell casting, we’re here to help. Today we’re going to provide you with a detailed guide on the types of love spells to cast. Not only that but there’s something for those who wish to find outside advice from more advanced spell casters. We’re also going to provide you with the top sites available to help you with your dilemma. Let’s begin our journey by educating ourselves on love magic and what a real love caster looks like. Love Magic and Love Casters Love magic made its first appearance back in Ancient Egypt and has been an active practice since. This type of magic is a branch of traditional magic and can be practiced in various ways. Typically the more common use of love magic is through the work of spells, but other methods look like Charms Rituals-LOVE Potions-Dolls and even Amulets If you are interested in becoming a love caster, be prepared for what’s to come. A genuine love caster knows that the art of love casting is no easy feat and shouldn’t be done casually. You should know that not only does it require you to be gifted spiritually, but you must be ready to serve others. Someone who is considered a real love caster has experience in all manner of spells, no matter the difficulty. Training yourself in attraction, commitment, and marriage spells is an excellent place to start. But this by no means will make you a professional. Practice your craft and expand your knowledge; understand that you will possess the ability to help others in time truly. Types of Love Spells What better way to start broadening your experiences with love spells than by learning more about them? These spells work like just about any other spell. Simply apply your intention, use a medium (sigils, mantras, candles, or charm bags), and top it off with establishing the belief that you will receive what you want. So what kind of spells are available and which ones suit your needs the best? Let’s take a look at the many options you have at your disposal.

And you don’t think it’s asking too much to want to be with a loving, intelligent man with a good sense of humour and daring, an upright and confident man – who knows who he is. No one wants a chauvinistic and macho man, but you do want someone who will be willing to protect and care for you. Who loves you for you and not some kind of imaginary. You have no doubt that when the right guy appears on your doorstep, you’ll never let him go. But sometimes a man doesn’t realize he has that good woman.

ADR, or Architecture Decision Record, is a valuable tool in software development for several reasons. It provides a centralized location for documenting and tracking architectural decisions, aiding both current and future team members. ADRs enhance communication among team members by documenting the rationale behind architectural decisions, especially beneficial during onboarding of new team members or when revisiting decisions. They serve as a knowledge base, enabling teams to learn from past decisions and refine their decision-making process. Additionally, ADRs contribute to transparency by helping stakeholders understand the reasons behind specific architectural choices. As with any other tool or process, introducing them into an organization can face several obstacles, and overcoming these challenges is crucial for successful implementation. In this talk I go through some common problems and our way of solving them.
