Eventhough there are many gadget blog out there, I still interested to have my own gadget blog. Being brief and short, that’s one of the main differentiation between my gadget blog and another blog. How about monetizing? Hmmm, I don’t have any plan to monetize my gadget in near times.

After upgrading to Ubuntu Karmic Koala (9.10), I try to install Ubuntu Netbook Remix in my wife’s HP MiniNote 1016. However since my wife doesn’t like it (it’s quite heavy in this machine), I decided to uninstall UNR and go back to the default GNOME.

There are several packages have to be removed, you can do that by writing this command in your terminal.

$sudo apt-get remove ubuntu-netbook-remix ubuntu-netbook-remix-default-settings maximus

There you go, UNR is removed and now back to GNOME default.

I have two hard drives, one is for daily use and another one is for backup needs. How to backup between those 2 hard drives in linux using command line (CLI) tools? Easy! Linux already have superb program called rsync, which can be used for backup or synchronize between two folder or drives or from hard drives to USB disk. Here is the command:

$ sudo rsync -avu –delete [source path] [destination path]

for example in my case:

$ sudo rsync -avu –delete /home/banteng/Business /media/2825dc9d-7018-49e0-bac4-2567a1d1a380/backup/Business/

options –delete (minus minus delete) is for deleting files or directories that is no longer exist in the source path, if you don’t use –delete then files or folder that is no longer exist still kept in the destination path.

You can combine this command with crontab so, you can run routine backup automatically for specific period, ie daily, weekly, etc….

By default, Ubuntu disable X window reset feature by keyboard shortcut in Jaunty (9.04) and Karmic (9.10). However we can still enable this feature, here is how:

1. Go to System > Preferences > Keyboard

2. Choose Layout Options

3. Choose  Key Sequence to Kill X Server, make sure it’s checked.

In Jaunty and previous release of Ubuntu, I used to install my SMC 2862 G driver using ndiswrapper, it’s a little bit annoying since sometimes it makes Ubuntu won’t boot perfectly (I should unplug and plug it again). But it’s just an old story, since now Ubuntu 9.10 Karmic can detect it perfectly, no Wind*** driver needed, no ndiswrapper installed, it’s just works out of the box.
