pg_dump is a nifty utility designed to output a series of SQL statements that describes the schema and data of your database. You can control what goes into your backup by using additional flags.
Backup: pg_dump -h localhost -p 5432 -U postgres -d mydb > backup.sql
Restore: psql -h localhost -p 5432 -U postgres -d mydb < backup.sql
-h is for host.
-p is for port.
-U is for username.
-d is for database.

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would

Hi, I'm mcpower. I've done Advent of Code seriously for two years now in Python, placing 9th in 2018 and 12th in 2017. This year, I'm taking a break from aiming for the leaderboard - while it's fun and all, it is a bit stressful at times (the good kind of stress, though!). As such, I'd like to share a few tips for anyone wanting to aim for the leaderboard.
This is everything that worked for me. Your mileage may vary, though - don't take this as gospel, see what works for you.
Go fast.

As part of a holiday D&D one-shot session where Santa Claus's toy factory had been sabotaged, our dungeon master presented to us, a group of Christmas elves, a riddle to solve.
9 cards, labeled with the names of Santa's reindeer were presented to us. The instructions indicated that we had to find the order reindeer were in, according to this riddle:
Vixen should be behind Rudolph, Prancer and Dasher, whilst Vixen should be in front of Dancer and Comet. Dancer should be behind Donder, Blitzen and Rudolph. Comet should be behind Cupid, Prancer and Rudolph. Donder should be behind Comet, Vixen, Dasher, Prancer and Cupid. Cupid should be in front of Comet, Blitzen, Vixen, Dancer and Rudolph. Prancer should be in front of Blitzen, Donder and Cupid. Blitzen should be behind Cupid but in front of Dancer, Vixen and Donder. Rudolph should be behind Prancer but in front of Dasher, Dancer and Dond
