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)

This is a resize of the actual EBS volume as opposed to adding additional disks using LVM
1. Follow the steps here: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/storage_expand_partition.html
2. Use the instructions for gdisk further down the page to set the new partition table, not gparted or fdisk.
3. Reboot the instance once the partition table is written.
4. On the instance, execute:

  sudo pvresize /dev/xvda2  (or whatever the device name is)

I assume no responsibility for the use of these instructions, or any negative impact they may have. You probably shouldn't do this. (Unless you really, truly hate vile cruftware like Java.)

Let the games begin

1. Reboot into Recovery Mode.
2. Power-on and hold ⌘ + R until Apple Logo appears.
3. If your hard drive is encrypted:
4. Start "Restore From Time Machine Backup"

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

# By default, Docker containers run as the root user. This is bad because:
#   1) You're more likely to modify up settings that you shouldn't be
#   2) If an attacker gets access to your container - well, that's bad if they're root.
# Here's how you can run change a Docker container to run as a non-root user

# Create the home directory for the new app user.
