Yet another Google Calendar Dashing widget

Yet another Google Calendar Dashing widget

Description

Dashing widget to display first two coming-up Google Calendar events.

Basically, you do not need more than two events on your dashboard, but it can be easily extended to the neighboring cells and show, say, 4 events instead of 2.

Краткое содержание

Принципы:

  1. Фокусируйте внимание на контенте, имеющем для вас какое-то значение
  2. Используйте язык как средство для коммуникации начиная с первого дня
  3. Если вы сначала поймёте то, что вам хотели сказать, то вы начинаете овладевать языком бессознательно (comprehensive input)
  4. Изучение нового языка - это также тренировка тела (правильное произношение зависит от мышц)

Python:

  • Factcheck -- requires a test framework (I like pytest), I wrote it (benefits - you can ask me about it, drawbacks - it's not very mature). Can be installed from PyPI with Pip or easy_install.
  • Hypothesis -- requires a test framework, provides decorators for easy integration
