PostgreSQL command line cheatsheet

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)

Install dlib and face_recognition on a Raspberry Pi

Instructions tested with a Raspberry Pi 2 with an 8GB memory card. Probably also works fine on a Raspberry Pi 3.

Steps

Download the latest Raspbian Jessie Light image. Earlier versions of Raspbian won't work.

Write it to a memory card using Etcher, put the memory card in the RPi and boot it up.

How to set up a pwnagotchi in 25* simple steps.
Preface:
I have no idea if any of this is the "right" way of doing it. This is just how I got my unit working.
Good luck.
WARNING: Do not use a V1 Waveshare display module with a stock pwnagotchi! The pwnagotchi expects a V2 module, and may irreparably damage a V1 module!
A V1 display module *can* work, but you must modify `waveshare.py` and `display.py` beforehand. For the time being, this is left as an exercise for the reader.
If you have already burnt a V1 display, try disconnecting it from the Pi and leaving it overnight. This may rejuvenate the display somewhat, but it will likely still display signs of damage.
Installation:
1. `dd` Raspbian Lite to an SD card.
