How to convert a Heroku Postgres dump to plain text

Sometimes you need to search within backups but don't want to restore the dump to a real database.

Backup files produced by Heroku Postgres are compressed. So they need to be converted to plain text.

Download a backup file and name it e.g. input.dump
Convert input.dump to plain text using pg_restore:

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.

Gollum Guard

Gollumn requires changes to be commited before the server will pick them up for display.

This is a simple workflow that uses guard livereload to continually amend a sessions commit while you work with local files in your gollum wiki. You can use this with any guard task, really, but I like live reload to refresh my broswer.

For live reload to work, you need the extension installed in your browser

Install with Homebrew

brew install redis

Set up launchctl to auto start redis

$ ln -sfv /usr/local/opt/redis/*.plist ~/Library/LaunchAgents

/usr/local/opt/redis/ is a symlink to /usr/local/Cellar/redis/x.y.z (e.g., 2.8.7)
