Once upon a time…
I once took notes (almost sentence by sentence with not much editing) about the architectural design concepts - Command and Query Responsibility Segregation (CQRS) and Event Sourcing (ES) - from a presentation of Greg Young and published it as a gist (with the times when a given sentence was heard).
I then found other summaries of the talk and the gist has since been growing up. See the revisions to know the changes and where they came from (aka the sources).
It seems inevitable to throw Domain Driven Design (DDD) in to the mix.

exiftool -filename -filemodifydate -createdate -r -if '(not $datetimeoriginal) and $filetype eq "JPEG"' .
###Output photos that don't have datetimeoriginal to a CSV### Note this can take a long time if you have a lot of jpgs

Magic words:
psql -U postgresSome 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)
