Unofficial Bash Strict Mode

Sometimes a programming language has a "strict mode" to restrict unsafe constructs. E.g., Perl has use strict, Javascript has "use strict", and Visual Basic has Option Strict. But what about bash? Well, bash doesn't have a strict mode as such, but it does have an unofficial strict mode:

set -euo pipefail

set -e

Google / YouTube Authentication using a Brand Account

Below describes the only way I was able to get (programmatic) access to the YouTube Analytics API on behalf of our Brand Account. Google documentation is convoluted, to say the least, so if you know a more straightforward way, please do share.

Getting a Client ID and Refresh Token

Create a Project in the Developers Console - https://console.developers.google.com/
Go to the Library tab and enable desired APIs (e.g. YouTube Analytics)
Go to OAuth consent screen and make project external. Select Test mode

Big-O Time Complexities for Elixir data structures

Map [1]

Operation	Time Complexity
Access	`O(log n)`
Search	`O(log n)`
Insertion	`O(n)` for <= 32 elements, `O(log n)` for > 32 elements [2]
Deletion	`O(n)` for <= 32 elements, `O(log n)` for > 32 elements

Deploying to Fly.io with SQLite

Deploying a Phoenix app to Fly.io is a breeze...is what everyone kept telling me. In fairness, I imagine the process would have been breezier had I just used postgres, but all the sqlite and litestream talk has been far too intriguing to ignore. "Wait", you say. "It is just a flat file. How much harder can it be?"

It is easy to make something harder than it should be. It is hard to take something complex and make it truly simple. flyctl launch does an amazing job at providing a simple interface to the utterly complex task of generating deployment resources, especially now that we are living in a containerd (erm, firecracker) world.

This gist is for anyone who, like me, thinks they know better than to read all of the documentation and therefore necessari
