PostgreSQL is Enough

Background and Cron Jobs

Using OTP's observer (appmon replacement) remotely

$ ssh remote-host "epmd -names"
epmd: up and running on port 4369 with data:
name some_node at port 58769

Note the running on port for epmd itself and the port of the node you're interested in debugging. Reconnect to the remote host with these ports forwarded:

$ ssh -L 4369:localhost:4369 -L 58769:localhost:58769 remote-host

Methods of Signing Git Commits on MacOS

Last updated March 13, 2024

This Gist explains how to sign commits using gpg in a step-by-step fashion. Previously, krypt.co was heavily mentioned, but I've only recently learned they were acquired by Akamai and no longer update their previous free products. Those mentions have been removed.

Additionally, 1Password now supports signing Git commits with SSH keys and makes it pretty easy-plus you can easily configure Git Tower to use it for both signing and ssh.

For using a GUI-based GIT tool such as Tower or Github Desktop, follow the steps here for signing your commits with GPG.

These three scripts can provide you a cursor style CMD+K Like experience in any terminal.

How it works

Set logged-shell to be your default shell for your terminal emulator. shell = /path/to/logged-shell in ~/.config/kitty/kitty.conf for kitty users.
This will stream both the inputs and outputs of your terminal session into a file defined at $SHELL_LOG_FILE
The ai-bash-command will take a user prompt, add the shell as context, and call OpenAI (with the ai command) to get the bash command that satisfies the prompt.
It will type the results back into your terminal using wtype for wayland users.

I have this abstraction in my application code called a "CloudFile". This is where I store in the database information about files on S3 and it gives me a resource for other resources to own. For example, a user would have an avatar_cloud_file_id. On the front-end, I would load this relationship and display the avatar with user.avatar_cloud_file.download_url

defmodule RL.CloudFile do
  use Ecto.Schema
  import Ecto.Changeset

  @timestamps_opts type: :utc_datetime_usec

Below are quoted from this discussion:

Alerts are an extension of Markdown used to emphasize critical information. On GitHub, they are displayed ith distinctive colors and icons to indicate the importance of the content.

An example of all five types:

	defmodule Uploader do
	@moduledoc """
	Source: https://samrat.me/til-file-uploads-using-the-req-elixir-library
	v0.4.5 of Req don't support file upload. Might as well use multipart
	"""
	def transcribe_audio(file_path, token) do
	model = "whisper-1"
	filename = Path.basename(file_path)
	{:ok, file_contents} = File.read(file_path)

	#!/bin/bash
	# Script to update a firewall rule in a Hetzner Firewall with your current IP address.
	# Good if you would like to restrict SSH access only for your current IP address (secure).

	#################
	# WARNING: This script will overwrite all rules in the firewall rules, so make sure you
	# added all the required rules.
	# I use a separate firewall rule just for SSH access.

	@doc """
	Renders an icon.

	Supports three icon libraries:
	- [Heroicons](https://heroicons.com) - prefixed with "hero-"
	- [Lucide](https://lucide.dev) - prefixed with "lucide-"
	- [Simple Icons](https://simpleicons.org) - prefixed with "si-"

	You can customize the size and colors of the icons by setting
	width, height, and background color classes.

	When writing Elixir code, perfer the following style guidlines:

	1. Elixir developers tend to create many small functions in their modules. I DO NOT LIKE THIS. Instead create functions that fully capture a conceptual task, even if it makes that function longer. A good rule of thumb is, if a private function is only called once within a module, it should've been inlined.


	For example:

	DON'T DO THIS:

	```elixir
