How to copy CD/DVD Disk in Ubuntu

Posted Sat, 07/21/2007 - 5:48pm by str

Duplicating CD or DVD in Ubuntu is so easy.

First we create an image of the CD/DVD to your hard disk drive.

sudo umount /dev/cdrom
readcd dev=/dev/cdrom f=file.iso

Right click on Image (ISO) file -> Write to Disc... -> Write

HyperTerminal replacement in Ubuntu - Minicom

Posted Fri, 06/22/2007 - 11:30pm by str

I was kinda surprise that HyperTerminal is not available anymore in Windows Vista. No problem, I rebooted my notebook to Ubuntu and fire-up minicom.

  1. By default, minicom is not installed in Ubuntu, so you need to install it first.
    sudo apt-get install minicom
  2. Find the name of your Serial Port
    dmesg | grep tty
    In the output look for something like "tty". The output in my case is like this:
    $ dmesg | grep tty
    [ 17.341823] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A

PHP5 for CentOS 4.4

Posted Tue, 02/27/2007 - 11:13pm by str

I’m using right now CentoS 4.4 and PHP5 is not yet part of the rpm package. I can always download the source and compile it or search some pre-pack PHP5 RPM and install it.

Alternatively, here’s how to do it using the good old yum one liner command.

  1. Edit CentOS-Base.repo
    vi /etc/yum.repos.d/CentOS-Base.repo
  2. Enable CentOSPlus by changing:

    #additional packages that extend functionality of existing packages
