gRPC Best Practice @ CoreOSFest 2017

https://coreosfest2017.sched.com/event/AWYc/best-practices-for-go-grpc-services-doug-fawley-google

Just small note for me. Hope the slide will be opened.

• API design
  • Idmpotency
    • It should be safe to retry an RPC without knowing whether it was processed
• Example

Postgres Cheatsheet

This is a collection of the most common commands I run while administering Postgres databases. The variables shown between the open and closed tags, "<" and ">", should be replaced with a name you choose. Postgres has multiple shortcut functions, starting with a forward slash, "". Any SQL command that is not a shortcut, must end with a semicolon, ";". You can use the keyboard UP and DOWN keys to scroll the history of previous commands you've run.

Setup

installation, Ubuntu

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)
