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?

# A self-extracting installer for RPMs
#
# To create: make a gzip-compressed tarball of RPMs (with no subdirectory),
# convert to base64, then concatenate onto the end of this file::
#
#   cd /some/directory/of/rpm/files
#   tar -cz *.rpm | base64 -w0 >> selfinstaller.bzx

Git Cheat Sheet

Commands

Getting Started

git init

or

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
