# This is just a cheat sheet:

# On production
sudo -u postgres pg_dump database | gzip -9 > database.sql.gz

# On local
scp -C production:~/database.sql.gz
dropdb database && createdb database
gunzip < database.sql.gz | psql database

  1. Add a comand to /etc/rc.local, add the following line above "exit 0": 
        setpci -s 00:1c.2 0x50.B=0x41
  2. Add the same comand to /etc/apm/resume.d/21aspm (which does not exist yet):
        setpci -s 00:1c.2 0x50.B=0x41
  3. Add the following to /etc/modprobe.d/sdhci.conf:
          options sdhci debug_quirks2=4
  4. Re-generate initrd:
         sudo update-initramfs -u -k all
  5. Reboot or reload sdhci module:

Bash tips: Colors and formatting (ANSI/VT100 Control sequences)

The ANSI/VT100 terminals and terminal emulators are not just able to display black and white text ; they can display colors and formatted texts thanks to escape sequences. Those sequences are composed of the Escape character (often represented by “^[” or “<Esc>”) followed by some other characters: “<Esc>[FormatCodem”.

In Bash, the <Esc> character can be obtained with the following syntaxes:

• `\e`
