rmt/src rmtsrc

Increases indentation on the file tree and adds some lines to each directory/file.

Works 15 levels deep, but you can expand it by just adding more of each line thats repeating, i.e.:

add another box shadow
- (n*-20px) 0 0 0 rgba(255, 255, 255, 0.4)
add another padding-left
- .monaco-tree-row[aria-level="n"] { padding-left: ((n-1)*20)px; }
add another :before & :after with left positioning
- .monaco-tree-row[aria-level="n"]:before { left: (((n-1)*20)-9)px; }
.monaco-tree-row[aria-level="n"]:after { left: (((n-1)*20)-9)px; }

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.

PostgreSQL JSON Cheatsheet

Using JSON in Postgres by example.

Quick setup via Docker

Download and install: Docker Toolbox
Open Docker Quickstart Terminal
Start a new postgres container:
docker run --name my-postgres -e POSTGRES_PASSWORD=mysecretpassword -d postgres

Tabs and Windows

Function	Shortcut
New Tab	`⌘` + `T`
Close Tab or Window	`⌘` + `W` (same as many mac apps)
Go to Tab	`⌘` + `Number Key` (ie: `⌘2` is 2nd tab)
Go to Split Pane by Direction	`⌘` + `Option` + `Arrow Key`
Cycle iTerm Windows	`⌘` + `backtick` (true of all mac apps and works with desktops/mission control)
