tmux cheat sheet

(CTRL-x means ctrl+x, ALT-x means alt+x)

Prefix key

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

# remap prefix to Control + a

An iTerm2 Cheatsheet

In the below keyboard shortcuts, I use the capital letters for reading clarity but this does not imply shift, if shift is needed, I will say shift. So + D does not mean hold shift. + Shift + D does of course.

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

How to migrate a Homebrew-installed PostgreSQL database to a new major version (9.3 to 9.4) on OS X. See upgraded version of this guide: http://olivierlacan.com/posts/migrating-homebrew-postgres-to-a-new-version/

This guide assumes that you recently run brew upgrade postgresql and discovered to your dismay that you accidentally bumped from one major version to another: say 9.3.x to 9.4.x. Yes, that is a major version bump in PG land.

First let's check something.

brew info postgresql

The top of what gets printed as a result is the most important:

Ask HN: Best Linux server backup system?

Linux Backup Solutions

I've been looking for the best Linux backup system, and also reading lots of HN comments.

Instead of putting pros and cons of every backup system I'll just list some deal-breakers which would disqualify them.

Also I would like that you, the HN community, would add more deal breakers for these or other backup systems if you know some more and at the same time, if you have data to disprove some of the deal-breakers listed here (benchmarks, info about something being true for older releases but is fixed on newer releases), please share it so that I can edit this list accordingly.

  • It has a lot of management overhead and that's a problem if you don't have time for a full time backup administrator.
