Python `@property` inheritance the right way

Given a Parent class with value property, Child can inherit and overload the property while accessing Parent property getter and setter.

Although we could just reimplement the Child.value property logic completely without using Parent.value whatsover, this would violate the DRY principle and, more important, it wouldn't allow for proper multiple inheritance (as show in the example property_inheritance.py bellow).

Two options:

Child redefines value property completely, both getter and setter.

Markdown - Resize pictures in GitHub

I found that the "best" way is to use HTML, as it works both in Readme/.md files and also in comments (within Issues, Gist...)

E.g. when adding/editing a comment (within Issues, Gist...) :

Upload the picture by drag-and-drop in the text field
replace ![image](https://your-image-url.type) with <img src="https://your-image-url.type" width="100" height="100">

As mentioned by @cbestow (thanks!), it's not mandatory to set both width and height. If only one is set, the other will be adjusted accordingly to preserve the aspect ratio of the image.

Python docstring reStructuredText style

Python Signatures

Signatures of functions, methods and class constructors can be given like they would be written in Python.

Demo:

Spoiler warning

Spoiler text. Note that it's important to have a space after the summary tag. You should be able to write any markdown you want inside the <details> tag... just make sure you close <details> afterward.

console.log("I'm a code block!");

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).

Hi everyone, Thanks for a lovely and productive session this week.
