A Nodejs implementation of a console transport logger based on Winston 3.x which also prints the filename and line-number
const winston = require('winston');
const { format } = winston;
const { combine, colorize, timestamp, printf } = format;
/**
* /**
* Use CallSite to extract filename and number, for more info read: https://v8.dev/docs/stack-trace-api#customizing-stack-traces
* @param numberOfLinesToFetch - optional, when we want more than one line back from the stacktrace
* @returns {string|null} filename and line number separated by a colon, if numberOfLinesToFetch > 1 we'll return a string

// console.log(colorCode, data);
// console.log(`${colorCode}some colorful text string${resetCode} rest of string in normal color`);
//
// ... and so on.
export const reset = "\x1b[0m"

ffmpeg youtube live event rtmp stream from raspberry pi with raspi camera (raspivid)
  1. compile ffmpeg for arm https://github.com/fiorix/ffmpeg-arm
  2. create youtube 'live event'. get rtmp url + session id
  3. run this:
raspivid -o - -t 0 -vf -hf -fps 30 -b 6000000 | ffmpeg -re -ar 44100 -ac 2 -acodec pcm_s16le -f s16le -ac 2 -i /dev/zero -f h264 -i - -vcodec copy -acodec aac -ab 128k -g 50 -strict experimental -f flv rtmp://a.rtmp.youtube.com/live2/<SESSION>

you can tweak -b and -fps to your liking. the settings above work well for 1080p. by not specifying width or height we get the full 1920x1080 resolution from the raspi camera

Approach for constants shared between modules in Elixir
defmodule Constants do
@moduledoc """
An alternative to use @constant_name value approach to defined reusable
constants in elixir.
This module offers an approach to define these in a
module that can be shared with other modules. They are implemented with
macros so they can be used in guards and matches
## Examples:
#Parse sysinfo output
eval $(/usr/bin/sysinfo -f -p | sed -e "s/^/SYSINFO_/")
#Config hostname
hostname your_hostname
#Setup hostname
eval "ipaddr=\${SYSINFO_Network_Interface_${SYSINFO_NIC_admin}_IPv4_Address}"
