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?

# NextCloud to BackBlaze B2 Backup Script
# Author: Autoize (autoize.com)

# This script creates an incremental backup of your NextCloud instance at BackBlaze's off-site location.
# BackBlaze B2 is an object storage service that is much less expensive than using Amazon S3 for the same purpose, with similar versioning and lifecycle management features.
# Uploads are free, and storage costs only $0.005/GB/month compared to S3's $0.022/GB/month.

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).
