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?

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)

I'm doing some research on how companies use GitHub Enterprise (or public GitHub) internally. If you can help out by answering a few questions, I'd greatly appreciate it.

1. What is the primary setup? Is there an organization and each official repo is owned by that organization?
2. Does every engineer have a fork of each repo they're working on?
3. Are engineers allowed to push directly to the official repo? Or must all commits go through a pull request?
4. Do engineers work on feature branches on the main repo or on their own forks?
5. Do you require engineers to squash commits and rebase before merging?
6. Overall, what is the workflow for getting a new commit into the main repository?
7. What sort of hooks do you make use of?
8. Are there any ops issues you encountered? (Scaling, unforeseen downtime, etc.)
