How to install Ubuntu from hard disk (without CDROM)

There are times when you need to (re-)install Ubuntu on your computer and at the same time you are in situation where booting from CD-ROM is not possible.

Luckily I found a post from Deepblue Spaces: Install Ubuntu 8.04 from Hard Disk that contains step-by-step to start Ubuntu installer from the official Ubuntu ISO.

  • It involves downloading the Official Ubuntu ISO from http://www.ubuntu.com/getubuntu
  • Extracting /casper/vmlinuz and /casper/initrd.gz from the ISO file.
  • And modifying /grub/menu.lst file to include the boot the cd image.

For more information, please refer to the original tutorial : Deepblue Spaces: Install Ubuntu from Hard Disk.

This trick is particularly handy when you are installing Ubuntu from a computer with buggy BIOS or where CD-ROM is not readily available

How to install *.rpm in Ubuntu / Debian based operating system

There are times when you need to install an application that is only available in *.rpm package in Debian GNU/Linux or Ubuntu operating system. One of the main obstacles is that Debian / Ubuntu are using *.deb based packaging system which is incompatible with RPM.

However you can easily convert RPM package to *.deb and install it afterwards, here’s how to do it :

  • Install alien, its available in Debian, Ubuntu repository
  • Convert rpm package using command “sudo alien -k some-binary-package.rpm”
  • Install it using this command “sudo dpkg -i some-binary-package.deb

That’s all about it! Have fun installing application in your application.

ImageMagick thumbnailer scripts for blog

Hey there, I’d like to share my dirt-easy script for creating thumbnail in blog post. The script will scale any image to the width of 456pixels which I find acceptable by most blog theme (actually the limit is around 460-465 pixel, but better be safe).

Why I wrote yet another script for scaling images? because I find blogger.com and WordPress system of uploading images and photo annoys me, and I rather upload my pictures/photos on my own private server and create thumbnails on my own.

I licensed the download under WTFPL , don’t worry its a free software license.

Download : thumbnailer.sh

Enable Network Printer Sharing with Ubuntu Linux computers

Having a shared printer within a computer network is a nice thing to have. Since all computers within the network can access a remote printer to print documents. Maintenance cost is much more cheaper and easier since you only need to service only a single printer within a network.

Here’s how to enable Printer sharing with Ubuntu (or other Linux based computers) through GNOME :

At the computer with the printer

Administer Printers Ubuntu
  • First at the Desktop, go to System->Administration->Printing. A dialog will appear
  • Go to Server Settings, and check the “Share published printers connected to this system” checkbox

    Administer Printers Ubuntu

  • You may, optionally select “Allow users to cancel any job”
  • Click Apply, and close the dialog

At the client computer(s)

Network Printer Sharing Ubuntu, using Samba

  • From the Desktop, go to System->Administration->Printing. A dialog will appear
  • Check “Show shared printers from other systems” checkbox. Click Apply
  • Repeat the first step, this time click “Refresh Printer Queues” button. You shall see the list of shared printer from the server computer
  • Repeat this on other computers on the network to share the printer

That is all to it! Now you can print documents across your computer network.
