VIM as an IDE for writing programs under Linux / UNIX

I'm already using few tips described here. From the article:

So I like vim a lot, and I've been using it on and off for a few years, but recently I've been using it full-time to code in Python. I learned a few things along the way and I made vim a better IDE for myself. Here's how.

You can follow along or go straight to author's .vimrc file. Place the .vimrc file in your home folder and enjoy the goodies.

The first step is to make sure you have the equivalent power of jedit, textpad, gedit and the like.

Configure Ubuntu Linux GRUB to load FreeBSD

Recently my friend emailed me an interesting scenario. He installed FreeBSD 6.0 / 7.0 in the first primary partition (10G). One day he installed Ubuntu Linux. He can boot into Linux but not able to boot into FreeBSD. Now, my friend wanted to boot both FreeBSD and Ubuntu Linux via Grub boot loader.

It is not that hard to configure grub to boot FreeBSD. You just need to add following three lines to grub configuration file (/boot/grub/menu.lst). Boot into Ubuntu Linux and use text editor to edit the file /boot/grub/menu.lst ( Red hat and friends [ Fedora / CentOS ] try /etc/grub.conf file) :
$ gksudo gedit /boot/grub/menu.lst
$ gksudo vi /boot/grub/menu.lst
Append FreeBSD boot Configuration:

title  FreeBSD 7.0
root   (hd0,a)
kernel /boot/loader

Save and close the file. To see changes or to boot into FreeBSD reboot Ubuntu Linux box.

  • title FreeBSD 7.0 : Start a new boot entry. User always sees this title and hit enter key to boot os.
  • root (hd0,a) : Actual part is to select the correct root partition. The root option set the current root device to the device, then attempt to mount it to get the partition size. In above example - hd0 is your first hard disk i.e. hda in Linux. In grub hda is hd0. Likewise your first, second partition on the first hard disk – hda1, hda2, becomes hd0,0 hd0,1 in Grub. In short, you are asking to use first hard first partition (remember FreeBSD use a,b,c names to represent partition names). If you have installed FreeBSD on third partition then you need to use following root statement:
    root (hd0,2,a)
  • kernel /boot/loader : Use to load the primary boot image. FreeBSD use /boot/loader to load rest of kernel and os.
