@brian_scanlan Nice one for this @BriAnimator_! I saw you also use a fast lane for reviews, how does this work? Assume you're skipping reviews for low risk PRs?

create extension if not exists "pgcrypto"; create table forum_example.person ( id uuid primary key default gen_random_uuid(), ... ); // (random) uuid creation in #postgres #postgressql, lovely.

Had to google this one this week to remind myself, but jest has a watch flag, which you can then configure via a text menu to run failing tests only for your TDD loop:
jest --watch // #javascript #nodejs

The basics of using #pyenv to manage your #python #python3 installs:

pyenv versions // list installed python versions
pyenv install 3.7.7 // install some version of python
pyenv global // list the current global python version
pyenv global 3.7.7 // switch globally to 3.7.7

(\n -> n < 0) 42 // anonymous functions in #elmlang, parentheses mark the function scope (so 42 is an argument to the function), and the \ starts the anonymous function declaration.

SELECT * FROM pg_stat_activity order by query_start asc nulls last; // useful one - get all current running queries on #Postgres

Records are a really nice way of working with data in #elmlang here's how you initialise one:
origin : { x : Float, y : Float }
origin =
{ x = 0
, y = 0
}

And here's how you update one:
{ point2D | y = 1 }
{ point2D | x = 1, y = 2 }

Infinite loops in #Golang are just a for loop with the condition omitted:
for {
} // you can omit the condition to proxy the behaviour of while (true)
