tmux cheatsheet

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

remap prefix to Control + a

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)

How to use

  2. write your route method, handling requests.

ffmpeg time-lapse

Convert sequence of JPEG images to MP4 video

ffmpeg -r 24 -pattern_type glob -i '*.JPG' -i DSC_%04d.JPG -s hd1080 -vcodec libx264 timelapse.mp4

  • -r 24 - output frame rate
  • -pattern_type glob -i '*.JPG' - all JPG files in the current directory
  • -i DSC_%04d.JPG - e.g. DSC_0397.JPG
  • -s hd1080 - 1920x1080 resolution

Slower, better quality
