Common Linux commands

List hard drives:
:$ su
:# sfdisk -s

List partition tables:
:$ su
:# sfdisk -l

Remove a default gateway:

Add default gateway, this will add as the default gateway:

xlib: connection to "unix:1012.0" refused by server - workaround

I was trying to open an X application (actually a GTK+ application) and got the error below :
Xlib: connection to "unix:1012.0" refused by server
Xlib: No protocol specified

(scite:8344): Gtk-WARNING **: cannot open display:
I think the reason why I am getting this error is that I changed user in terminal from regular account to root. I've read in the net that user can use xhost + but it is not working for nxserver+nxclient. But there is a very easy workaround for this if sudo is installed and enabled.
#: sudo scite
This will open the scite text editor in an elevated account (root user).

Logitech QuickCam VC USB driver for Windows XP

We bought a webcam in yard sale, it is a Logitech QuickCam VC model LKD5 part number 1049-640-001. As we all know, most items bought in yard sale does not come with a driver. A quick visit to Logitech shows that they don't provide a driver for Windows XP for this device. Here comes google. After few minutes of surfing I finally found a driver that works for this hardware. Get it from here. If you need to get the driver from the original publisher visit here. Note: don't install any software from Logitech as it may interfere with the functionality of the driver. Just use Yahoo Messenger or MSN Messenger. You should be all set.

Enabling Cleartype font for Windows XP

I wish I had seen this website long time ago... MS Windows have this really useful utility to increase the readability of fonts specially on LCD monitors. Please go check the following website :

You need to use Internet Explorer to make this work.

2008/07/21 Update
This also applies to Vista. I just upgraded one of my laptops and it was quite hard to read screen display both on the laptop and when docked with default settings. Tuning did help quite a lot.

Running Macintosh inside your USB

I have come across this post today and it seems interesting. It allows you to run Macintosh upto 7.5. There is a sample image here. I had difficulty following the instruction from minivmac site due to .sim.bin file that I can't manipulate in Windows. Even Stuffit Expander does not really help when running in Windows.
