I am trying to create a very basic class: Line as follows:

self._x1 = x1
self._y1 = y1
if dx is None:

Actually, it was unclear, at least to me. But perhaps it is perfectly clear to others.

The goal of the function is to find out how to get from one angle to another angle. Two things are involved: the amount to move by and the direction (+ means turn right, - means turn left). The most the angle will have to move by is 180deg. The function is rather short. I wanted to avoid using an...
I have recently tried to get a better grip on machine learning from a point of implementation - not statistics. I've read several explanations of an implementation of a Neural Network via pseudocode and this is the result - a Toy Neural Network.
I have used several sources from medium.com and tow...
A couple of us disagreed (in comments) on whether titles such as "Advent of Code 2019 Day 3, Part 3" and "Project Euler nº 5" are reasonable.
I believe that such titles are meaningless, and reviewers want some idea of the problem domain when deciding whether to read a question, but there seems t...

It’s my birthday today and I’ve got a gift for you. 🎁 We’re lowering the close/reopen vote threshold on Stack Overflow from 5 to 3.
About a month ago, Shog shared the results of our experiment testing this lower close/reopen threshold. From that, we observed that closing, reopening, and editing...
One of the great secondary benefits of an open knowledge base like Stack Overflow for Teams is that anyone can contribute. When exceptional answers get voted to the top, your organization gets to identify subject matter experts. Today we’re excited to announce our new subject matter expert feature that allows domain experts to be easily recognized and acknowledged within your organization.
The new feature, available on the Business tier of Stack Overflow for Teams and coming to the Enterprise tier in 2020, allows your Team to associate a subject matter expert (SME) with a tag. Multiple Team members can be designated as SMEs for any given tag by your Team Admin. …
