Effectiveness and Java-code optimization на JUGUA (4 декабря)

November 23rd, 2015 6 comments

Коллеги, приглашаем Вас на первую зимнюю встречу JUG UA, на которой выступит гость из Одессы Сергей Моренец, автор книги “Development of Java applications” и сайта it-simulator.com

Дата: пятница, 4 декабря, с 19:00 до 22:00
Адрес: ул. Кудряшова, 14-б (кафетерий), офис EPAM Systems


Программа встречи

– Эффективность и оптимизация кода в Java приложениях (Сергей Моренец) видео, слайды

Если мы захотим понять, что такое совершенный (идеальный) код, то одной из его характеристик будет эффективность. Это включает в себя и быстродействие кода, и объем потребляемых ресурсов (память, дисковых, I/O).
Зачастую эффективность отодвигается на второй план, поскольку ее не так просто рассчитать заранее, а также точно определить на ревью кода. В то же время это единственная характеристика, которая затрагивает конечного пользователя наших проектов.
В моем докладе я рассмотрю, что такое эффективность, как ее правильно измерять, мы коснемся мифов об эффективности, которые очень популярны сейчас, рассмотрим примеры эффективного и неэффективного кода, нужной и бессмысленной оптимизации кода.

Активных участники встречи, ждут лицензии от JetBrains.

Workshop ‘Building REST services with Spring MVC REST, Spring Data REST and Spring HATEOAS’

November 5th, 2015 No comments

Очевидно, что это тренинг про весну, отдых и ненависть. А если подробней, то мы научимся строить REST сервисы с помощью Спринга.

Начём с понимания, что такое REST, какое отношение он имеет (или не имеет) к Веб Сервисам, и почему он хорош.
Обсудим подход HATEOAS и наконец поймем кого он ненавидит и за что.
После этого разберемся зачем нам 3 разные библиотеки для построения REST API в одном Спринге (ответ “а у них всегда так” принимается, но может есть лучше?) и всё таки поймем в чем разница между похожими, но все таки разными инструментами – Spring MVC REST, Spring Data REST и Spring HATEOAS.
Ну, и код. Как всегда, будем писать код.

Тренер: Baruch Sadogursky (http://lanyrd.com/2015/javadaykiev/sdrhbf/)
Дата: 8 ноября
Время: 10:00 – 18:00
Стоимость участия: 3000 грн.
Место проведения: EPAM, Кудрряшева 14б

September 29th, 2015 2 comments

Коллеги, приглашаем Вас на осеннюю встречу JUG UA, на которой будет представлен доклад с трех крупных европейских конференций.

Дата: среда, 7 октбря, с 19:00 до 22:00
Адрес: ул. Кудряшова, 14-б (кафетерий), офис EPAM Systems


Программа встречи

– Performance testing: the way to make a true load (Izzet Mustafaiev)

If you heard about web-scale or have a requirement to survive under web-scale or you just would like to prepare your application to handle an X effect this topic is for you. During a presentation you will understand aspects and caveats of performance testing, nuances of performance testing of Java based web applications. As a practical part you will get a brief overview of existing tools and will get a guide of using Gatling as a tool to make a load for your application. Gatling is an open source tool for performance loading written in Scala and provides comprehensive DSL for load scenario specification.

– Spock: live long (code short) and prosper (Yaroslav Yermilov)

JUnit is in the game for a years and can be considered as the most popular Java library ever. But when have you heard about new features in JUnit last time? Isn’t it time to look at something new and modern?
For example, Spock — beautiful and highly expressive testing and specification framework. As many citizens of Groovy world, it’s in the same time highly compatible with existing Java infrastructure and, thanks to Groovy power, has amazingly clean and powerful DSL.
In this talk, we will look at variety of Spock feature and try to find answer how does testing beyond JUnit may look like.

Активных участники встречи, ждут лицензии от JetBrains и билеты на JavaDay Kyiv.

Dr. Venkat Subramaniam TDD master class

September 13th, 2015 No comments

Many organizations are working hard to be agile. They have mostly mastered the non-technical aspects of agile development, however, the major impediments come from not embracing some key technical practices. Evolving an application requires, amount other things, evolving the design and architecture, but that has risks.

In this workshop, we will focus and learn some key technical practices that will help us evolve applications based on the feedback cycles that agile development heavily relies upon. We will learn design principles and practices that help reduce risk involved often in evolving software. Read more…
