Postgresql password authentication
Scripting automation tasks for postgresql can be done easy.
By default ( In Debian and Ubuntu ) postgresql uses IDENT as method
for authentication. This means that the user “postgres” only can connect
to the database if the unix user is logged in or sudoed. In my version 8.4
/etc/postgresql/8.4/main/pg_hba.conf has a line witch should be modified .
Replace ident with password, and here you go.
Mount ddrescue file
You can do fdisk on the image file, via a loopback
device:
Load data file / image file made with
losetup -r /dev/loop0 drive.ima
fdisk -lu /dev/loop0
The you will see something like this;
Disk /dev/loop0: 4009 MB, 4009754624 bytes
84 heads, 22 sectors/track, 4237 cylinders, total 7831552 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xc5328fd3
Device Boot Start End Blocks Id System
/dev/loop0p1 * 62 7831551 3915745 4 FAT16 <32M

or http://www.embedupload.com/?d=02MTABK2G3
4.Then flash http://android.clients.google.com/pa…D.5a07884d.zip or http://www.mediafire.com/?wd0ureeywv44ld7
5. Reboot, and you should be on Jelly bean 4.1 
These exact steps are untested by me ( i dont have a gnexus) but should work fine

Windows 2008 r2 setup KVM
Installing Windows 2008 r2 on KVM resulted in some issues. The screenshot shows the first error, below i will explain how to solve this problem.
After some search i found out the ISO was corrupted. Downloading again from their super fast ( not really ) servers seems to be enough.
So installing windows on a Debian Squeeze KVM system;
step 1. Download the correct .iso file
step 2. Get the latest virtio-win .iso file from the Fedora Linux project; http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/bin/
step 3. Go to the
virt-install –connect qemu:///system -n win2k8 -r 1024 –vcpus=2 –disk /dev/vg1/windows –vnc –noautoconsole –os-type windows –os-variant win2k8 -c /mnt/test/dvd2.iso –disk path=/mnt/test/virtio-win-0.1-22.iso,device=cdrom,perms=ro
The Virto Win part is needed for Windows en Qemu to find the correct harddisk drivers. Else the setup will get stuck or slow down really bad ending with a message; “No harddisks found”
After this continue installing with virt-manager, the VNC option will make it possible to do a GUI Windows install.
