So, let’s edit the .vimrc file, which actually is at VIM_INSTALL_PATH\_vimrc (for instance C:\Program Files\vim\_vimrc with the default install options).
Disabling backup files is as simple as adding

set nobackup

Getting visual mode arrows selection is a bit different, as explained in vim tip 864 comments, you can either add

set keymodel-=stopsel

around the end of the file
or drop the

behave mswin

line from the default vimrc.

Here are two other (non windows-specific) tips:
Bash like filename completion:

set wildmode=longest:full
set wildmenu

Pythonic smart indent:

autocmd BufRead *.py set ai et ts=4 sw=4 sts=4
autocmd FileType python set ai et ts=4 sw=4 sts=4
autocmd BufRead *.pyx set ai et ts=4 sw=4 sts=4
autocmd BufRead *.py set smartindent cinwords=if,elif,else,for,while,try,except,finally,def,class

Wondering how it looks? Here is the output of a little test:

ixce@timmy:~$ sudo shutdown -r
W: molly-guard: SSH session detected!
Please type in hostname of the machine to shutdown:
Good thing I asked; I won't shutdown timmy ...

Since it doesn’t correctly handle sudo yet (actually sudo is at fault here, since it drops SSH_CONNECTION environment variable when doing its stuff), you might want to add PRETEND_SSH around the beginning of /usr/sbin/shutdown as specified on Nico “nion” Golde’s blog.

You might also want to grab the molly-guard 0.3.2 etch package I backported from sid (all I changed is downgrade debhelper build-dep version and debhelper compatibility level in debian/compat since etch only has debhelper 5 and the sid package required debhelper 6 ; this shouldn’t break anything since the newer debhelper just seems to be needed to recognize a few fields in debian/control about where the package is maintained). Sources are also available, anyway.

Thanks hr for the tip

Here is a quick snippet demonstrating it, which will create a form with n integer fields named from 0 to (n – 1), but you will easily be able to heavily extend it.

from django import newforms as forms
 
class MyForm (forms.Form):
 
    def __init__ (self, n, *args, **kwargs):
        forms.Form.__init__ (self, *args, **kwargs)
        for i in range (0, n):
            field = forms.IntegerField (label = "%d" % i, required = True,
                                        min_value = 0, max_value = 200)
            self.fields["%d" % i] = field

Could you please keep this little tip safe and warm?
If your friendly Xen hypervisor stops outputting during the boot process at some point and completely freezes, or just stops until you get X or so, just add “console=vga vga=keep” to your Xen kernel line in your GRUB configuration, so that it looks like this:

title Xen 3.1
root (hd0,4)
kernel /xen-3.1.gz console=vga vga=keep noreboot
module /vmlinuz-2.6.19-4-generic root=/dev/mapper/lvm-root ro console=tty0
module /initrd.img-2.6.19-4-generic


Thanks dear.
