Scratch files
Scratch buffers are simple text files without any coding assistance features. Scratch buffers can be used for simple task lists and notes to yourself. They are also not stored in the project directory but can be accessed and opened from another project. You can create up to five scratch buffers with default names, which are rotated and reused by clearing the content.
Create scratch files
When you create a Java scratch file, IntelliJ IDEA automatically adds a class declaration and a main() method.
IntelliJ IDEA numbers scratch files sequentially starting from 1. If you close a tab with an empty scratch file, IntelliJ IDEA deletes it.
If a scratch file grows into something that you want to use in your project, you can easily move it into the desired place of your project structure.
Include a scratch file into your project
Drag a scratch file from the Scratches and Consoles | Scratches directory in the Project view to the target directory in your project.
Create scratch buffers
There is no dedicated menu item for the action to create a new scratch buffer, but you can use the Find Action popup Ctrl+Shift+A and run the New Scratch Buffer action.
You can also add a shortcut for the New Scratch Buffer action as described in Configure keyboard shortcuts.
View all scratch files and buffers
Consoles are used to compose and execute SQL statements for databases defined in IntelliJ IDEA as data sources. This functionality is available only when the Database Tools and SQL plugin is enabled. For more information, see Query consoles.
Use the Find Action popup Ctrl+Shift+A to invoke the Show Scratch Files action and view all available scratch files in a popup:

Scratch files support syntax highlighting for the corresponding file type, and you can use them to draft any code instances, from C/C++ constructs to JSON documents. For example, while working on one project, you may come up with an idea for a method that you could later use in another project. You can create a scratch file with a draft of the method, which is not stored in your project directory but can be accessed and opened from another project.

The Project in the IntelliJ system is equivalent to the workspace in the Eclipse system.
The Module in the IntelliJ system is equivalent to the Project in the Eclipse system.
A Project in IntelliJ can include multiple Modules, which is equivalent to creating multiple projects in the Eclipse workspace.
2. Scratches and Consoles in IntelliJ IDEA
Intellij IDEA provides two temporary file editing environments. Through these two temporary editing environments, you can write some text content or some code fragments. Two kinds of Scratches are: Scratch files and Scratch buffers.
This function is used by idea to test a small piece of code or a certain statement, a certain api, etc. It is very convenient;
Scratch files: Scratch files have complete running and debugging functions, etc. These files need to specify the type of programming language and specify the suffix.
Create Scratches:
Select File | New | Scratch File on the Main Menu
Ctrl + Shift + Alt + Insert shortcut keys
Right-click anywhere in the Project window and select New | Scratch File/buffer
Press the Ctrl + Shift + A shortcut key, then enter scratch file/buffer, select the new option found to create a scratch file.

I personally like this API file. You can directly test the interface (get request) in idea without opening postman.
Tips:
Rotate the java code and press Ctrl + Shift + Alt + Insert, it will directly generate a Scratch File of the java code you selected, and then you can run it directly to check for errors 
Новый PyCharm 4.5 собрал вместе все инструменты для работы с Python
Всем привет! Мы выпустили новый PyCharm 4.5, который уже доступен для скачивания.
С момента предыдущего релиза PyCharm 4.0 прошло ровно полгода. За это время PyCharm получил ряд новых полезных инструментов для Python, Django и веб-разработки, которые, как всегда, тесно интегрированы и эффективно работают друг с другом. Сегодня мы рады рассказать, что же интересного и важного появилось в новой версии PyCharm.
В первую очередь, отметим появление интегрированного Python-профилировщика:
Теперь вы можете с легкостью собирать статистику работы вашего приложения прямо в PyCharm, а также просматривать результаты в виде графа вызовов функций. Также предусмотрена навигация из графа в код. Профилировщик корректно работает на удаленных машинах. Поддерживаются два популярных профилировщика: yappi и cProfile.
В PyCharm 4.5 мы серьезно улучшили отладчик, который теперь поддерживает режим встроенной отладки. Значения переменных, параметров функций и прочих объектов доступны прямо в окне текстового редактора:
Интерактивный режим matplotlib теперь доступен как из Python-консоли, так и из консоли отладчика. С его помощью можно рисовать, обновлять и инспектировать графики в режиме реального времени:
Кроме всего прочего, в отладчике теперь поддерживаются две новые возможности: Ignore library files (игнорирование библиотечных модулей) и Step into my code (трассировка только по коду проекта). Первая позволяет останавливать отладчик в коде проекта при возникновении исключения в библиотечном коде, а вторая — шагать в режиме отладки только по коду проекта, не углубляясь в библиотечные исходники:
Также в режиме отладчика появился переход из окна отслеживания переменных (variables view) в код:
Разработчиков Django должна порадовать новая консоль manage.py. Теперь эта полнофункциональная консоль поддерживает автодополнение команд и их аргументов, хранит историю команд и позволяет просматривать краткую документацию для команд со ссылками на официальную документацию Django:
В этом выпуске мы также поддержали свежий Django 1.8.
Программируйте с удовольствием!
