This is the script for sandeep when he asked me how to delete a directory in perl. rmdir function only removes empty directories. So we need to remove the contents of the directory before removing the directory. So if the directory contains more directories / folders we would have to recursively delete all the directories under the directory. Well so here is the code just to do that.

code

File : hello.go

package main
import "fmt"
 
func main() {
	fmt.Printf("Hello World !!! \n")
}

Compiling & Running

 8g hello.go 
 8l hello.8
 ./8.out

Output

Hello World !!!

(Obviously )

So when I was sitting idle, moosa asked me how to add dynamic textboxes into a form without loosing values of the form values on the previous textboxes.

So I thought of documenting the method here just in case anyone of you might want this.

So we have a form with a text box as shown below :

The goal is to add a form as shown below, Clicking the Add More link will add more input boxes to the html form dynamically.

Ubuntu 9.10 ships with the new GRUB (Grand Unified Boot Loader 1.97 beta) in plain words its the software that boots the operating system you choose when you boot the computer. In earlier versions of Ubuntu / Grub to change the menu on the grub screen, one had to edit the /boot/grub/menu.lst file. In the new system this a little different from just editing the one file.

The GRUB configuration now resides at /boot/grub/menu.cfg But do not edit this file as it is generated from files from /etc/grub.d/* and /etc/default/grub.
