Just some notes and references for myself.

• In bash, you can access your C:\ drive via /mnt/c/
• ~ = C:\Users\MLM\AppData\Local\lxss\home\mlm and is different from your Windows user directory C:\Users\MLM

How to google things

#!/usr/bin/env bash

# Фейковый npm
# Нужен для кэширования папки node_modules
# Кэш находится в папке ~/.cache/npm-inject/[sha1 хэш файла package.json]/node_modules
# 
# В PATH надо добавить путь папки с фейковым npm, таким образом при выполнении команды `npm install` 
# bash вызовет фейковый npm c параметром `install`.
# Фейк проверяет наличие папки [sha1 хэш файла package.json] в кэше.
# Если она в кэше, создаем на неё симлинк node_modules

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?
