• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

Common Unicode Subsets
======================

ASCII

Not exactly known as a Unicode subset; the Unicode character set starts with
ASCII, though; therefore, ASCII is the smallest widely-used subset of
Unicode.

mongoose.connect('mongodb://localhost/test');
 
var db = mongoose.connection;
 
db.on('error', function() {

Most active GitHub users (git.io/top)

The count of contributions (summary of Pull Requests, opened issues and commits) to public repos at GitHub.com from Wed, 21 Sep 2022 till Thu, 21 Sep 2023.

Only first 1000 GitHub users according to the count of followers are taken. This is because of limitations of GitHub search. Sorting algo in pseudocode:

githubUsers
 .filter(user => user.followers > 1000)
