Вадим развеял сомнения относительно данного вопроса. И уточнил, какие задачи относятся к роли проектного менеджера. И возможные конфигурации выполнения этих задач участниками команды в так называемых командах без менеджеров.
«Ruby beta-test в Jelastic» Volodymyr Iliushenko,
Владимир предоставил информацию об открытии ruby хостинга на Jelastic
«Tracking configuration changes. Using git for updating large field values in UI» Андрей Кирилленко,

Михаил очень подробно показал с примерами процесс интерпретации ruby кода и на основе исследования дал несколько рекомендаций по поводу опитмизации кода
Денис усовершенствовал свой доклад и очень ясно и просто объяснил на примере как, для чего и почему нам нужен Arel. Также Денис сделал несколько сравнительных тестов по производительности и привел их результаты в своем докладе.
Живая дискуссия вместо часа длилась полтора часа и пролетела в один миг. Тарас, Дима, Артур и Богдан рассказывали свой опыт и разбирали заготовленные примеры, а слушатели активно дополняли их рассказ своими примерами и рекомендациями. Получилось очень интересно и полезно.
План дискуссии за круглым столом: «Оптимизация SQL, Ruby, Rails»:
1. Когда в ORM все хорошо и без доп. магии
Маленькая база
Простые запросы
Eager loading
2. Когда SQL, когда обработка кодом 3. Когда хорошо работает «тюнинг»
