So you've cloned somebody's repo from github, but now you want to fork it and contribute back. Never fear!

Technically, when you fork "origin" should be your fork and "upstream" should be the project you forked; however, if you're willing to break this convention then it's easy.

* Off the top of my head *

1. Fork their repo on Github
2. In your local, add a new remote to your fork; then fetch it, and push your changes up to it

    git remote add my-fork git@github...my-fork.git

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

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

• 1.json contains data retrieved from the Instagram API. data is an array of media matching the query posted to Instagram's REST API, in a JSON array.
• Each media element contains metadata for a photo/video posted to Instagram
• .data[] loops over each media object in the JSON file, letting us process each element
• | works like a regular *nix pipe, taking the output of the previous operator and passing it on to the next one.
• select() filters through objects depending on the rule passed to it.
• .tags[] returns an array of tags for each media. contains() returns true if the current object passed to it contains the string passed as a parameter. .tags[] | contains("100happydays") iterates over all the tags associated with the media object and returns true if the current tag matches the string 100happydays.
• .select( .tags[] | contains("100happydays") ) filters all media objects that contain the tag 100happydays
• .images.standard_resolution.url now

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)
