Mac OS X – Relocating the Home Directory Off the Boot Drive

Uncategorized, , , , ,

Moving your home directory

Don’t email me for help. This is an advanced maneuver, you’re on your own!

Don’t even think about doing this without making a clone of your system first!

Go into System Preferences => Accounts, and select the account you’d like to move; click the lock to unlock.

Users control panel in System Preferences

Choose Advanced Options… by right-clicking or control-clicking on the account you want to relocate:

Advanced options

Next, copy your home directory to the desired location, then change it using the Choose… button as shown below. Don’t mess with anything here unless you really know what you are doing.

Wrapup

Do not forget—

  1. After making these changes, immediately reboot, then REMOVE your original home directory to avoid confusion.
  2. Don’t forget to create another admin account that resides on the boot drive, so that you login if your regular account is on a volume that “goes away”.

Having Flash installed can cut battery runtime…

Uncategorized, , , , , , , , ,

Having Flash installed can cut battery runtime considerably???as much as 20 percent in our testing. With a handful of websites loaded in Safari, Flash-based ads kept the CPU running far more than seemed necessary, and the best time I recorded with Flash installed was just 4 hours. After deleting Flash, however, the MacBook Air ran for 6:02???with the exact same set of websites reloaded in Safari, and with static ads replacing the CPU-sucking Flash versions.

??? ArsTechnica

Just having Flash enabled cost 2 hours of battery life.

Time to kill Flash?
I’m doing my tests in that direction …

solutions of a Gnome desktop showing the contents of home folder

Uncategorized, , ,

After a quite painful restore procedure of my files for a Fedora 12 reinstallation (I needed to clean up better before backup) I found my (Gnome) desktop showing the content of my home folder.

A quick google-search and I’ve found the solution:

nano ~/.config/user-dirs.dirs 

Here you can modify various “line” and behaviours, the one we need the most is:

XDG_DESKTOP_DIR=”$HOME”

how to use users-admin remotely on Ubuntu

Ubuntu, , , ,

Lately I had the necessity to create an account and modify another one on an Ubuntu box at work. I’ve regularly logged on via a ssh -X shell and gave the command 

sudo users-admin

resulting in a “blocked” window … I mean one on which I wasn’t able to unlock the command via an administrative password input.

After a little diggin’ on the web I found that the solution is in giving this command:

sudo ck-launch-session users-admin &

which will ask you the administrative password and make the commands on the appearing window
