Installing Pspice under Ubuntu

Recently i was asked if one could install Pspice under Ubuntu. Here is a post outlining a method using Wine. It looks promising, though i haven't tried it out yet http://translate.google.com/translate?hl=en&sl=fr&u=http://doc.ubuntu-fr.org/wine&ei=H5JtTJ_eNIW2vQODgam4DQ&sa=X&oi=translate&ct=result&resnum=2&ved=0CBsQ7gEwAQ&prev=/search%3Fq%3Dplayonlinux%2B%2522pspice%2522%26hl%3Den%26sa%3DG

For the tech savy

For those of you who feel Ubuntu is boring and has got nothing to offer. Well, here is a very nice article i just came across http://www.unixmen.com/linux-tutorials/937-things-to-do-after-installing-ubuntu-1004-lts-lucid-lynx

P4E-I Lab 1 & Lab 2 Fall 2010

We have covered a lot of Linux basics. Please refer to my older post for links to online tutorials and further reading http://zaidmunir.blogspot.com/2010/06/useful-links-for-learning-linux.html

DCN lab 2 - FALL 2010

In this lab we will be learning tcl and Otcl. The lab manual has been placed at the photocopier you are supposed to fill it up and submit it by the end of today's lab.

You can google and follow any tutorial on tcl that you wish. A list of tcl tutorials is also given here:

Quote of the day

"Muft ke cheez mein makhi zaroor hoti hai", Shoaib Bhatti.

So true for Ubuntu :p :D

Ubuntu suxs when you get to know it well! Its a nightmare

Make sure you do this

sudo dpkg-reconfigure adduser

Give "no" for an answer

Also don't forget to add this line to ~/.profile

umask 077

Then you may also want to do this

cp ~/.profile /etc/skel

this will change the default (pathetic) rights on files created by a user form 755 to 700. Note: this change will only be for users that are added after you made this change.

Or instead of changing and copying the ~./profile into etc/skel you may just simply change /etc/profile. At the end of this file you would find umask 022 change it to 077. Enjoy :)

Recovering lost Ubuntu installation after installing windows

You can  try installing and using Boot-repair, for instructions on installing and using it refer to the following link. (Note: i have not personally tried it but seems user friendly)
https://help.ubuntu.com/community/Boot-Repair

Or alternately you can choose to do it manually

Boot from a live cd of Ubuntu 10.04.
First, find out about your drives.

sudo fdisk -l

Then check to see if the drive is already mounted or not

df

If it is not mounted then mount it first. This is the drive in which Ubuntu is installed. In this example i will be mounting /dev/sda2 on to the folder /home/mtf

mkdir /home/mtf
sudo mount /dev/sda2 /home/mtf

In case you are not sure which drive has Ubuntu installed, you would like to look for a drive with System field as "Linux" in the output of sudo fdisk -l
If you have multiple such drives and are confused, then you can check the drives by mounting each of them and looking at the contents to see which is which. You can mount multiple drives on different folders using the steps mentioned above. You may also mount to the same folder (not consecutively) by unmounting the former drive.In this example /dev/sda2 is unmounted and /dev/sda3 is mounted in its stead

sudo umount /home/mtf
sudo mount /dev/sd3 /home/mtf

Once the drive is mounted

sudo grub-install --root-directory=/path-of-mounted-drive-with-ubuntu-install /dev/sdx

Replace x with the letter for your hard disk.

In my example, /dev/sda3 is the drive with Ubuntu installation, mounted on /home/mtf so the command would be

sudo grub-install --root-directory=/home/mtf /dev/sda

Note that in the above case it is /dev/sda and NOT /dev/sda2

Additionally to ensure everything is in order boot into your Ubuntu and then do the following to fix any missing or malfunctioning entries in grub

sudo update-grub
