-A Live Ubuntu USB Stick for Computational Neuroscience

+A Live Ubuntu/NeuroDebian USB Stick for Computational Neuroscience
+====================================================================
-I recently prepared a Computational Neuroscience `Ubuntu 11.04`_ USB Stick image, which NeuroDebian_ kindly offered to host. This USB stick will let you run a full `Live Ubuntu Linux`_ system **without installing anything on your hard drives**, and it includes `persistent storage`_ that **maintains new files and packages across reboots**. The system is bundled with several computational neuroscience tools like GENESIS_, NEURON_ and XPPAUT_. It is made to fit in USB sticks of size >1GB. To use it, you will have to restart your PC with the USB stick inserted. After you turn on your computer, you will possibly also need to bring up your boot menu and choose to boot from the USB stick (most likely by pressing F10 or F12).

*Note: You do not have to reboot your computer if you have a virtual machine* (e.g., `VirtualBox <http://www.virtualbox.org>`_, `VMware <http://www.vmware.com/>`_, etc.) *and you can point it boot from the USB stick.*

-In general, a USB stick is not preferable media for a day-to-day use of Linux because flash memory has a short lifetime (on the order of about several months to a year, based on usage). In addition to the chance of hardware failure over a long time frame, the Ubuntu Live CD also has a tendency to slowly `get corrupted over time`_, but with special care taken, it can be used safely.

+ RULES FOR KEEPING YOUR FILES SAFE:
-1. NEVER YANK OUT THE USB STICK WHILE UBUNTU IS RUNNING. PERFORM PROPER "SHUTDOWN" FIRST.

-2. REGULARLY BACKUP DATA FROM USB STICK ONTO HARD DRIVE

*Disclaimer: I take no responsibility over lost data whatsoever. By using this image, you assume all responsibility of your data.*
--------------------------------------------------------
Do this routinely to save your new files on the USB stick:
-1. While running Windows, insert USB stick
+1. While running your favorite PC operating system, insert USB stick
2. Copy file "casper-rw" on your Desktop, preferably with a date
To restore it, copy it back on the USB and make sure it's named "casper-rw"
-Transferring the persistent storage to your Windows hard drive:
+Transferring the persistent storage to your hard drive:
---------------------------------------------------------------
-1. While running Windows, insert USB stick
+1. While running any host operating system, insert USB stick
2. Copy file "casper-rw" to the root of one of your hard disks (e.g. C:\\casper-rw). Ubuntu will find it and use it from there. Keep on making backups of it as it can still get corrupted over time.
What to do in case of corruption and boot failure:
--------------------------------------------------------
You can either:
-1a- Copy your backed up "casper-rw" file onto the USB disk. You will lose your changed files since last backup.
-1b- Boot the USB stick by choosing a non-persistent boot option from the Ubuntu boot disk and perform a filesystem check. Once you get a terminal. Issue:
-$ sudo su -

Which should give you root access. And then run the disk check:
-# e2fsck -p /cdrom/casper-rw
+
+::
+
+ # e2fsck -p /cdrom/casper-rw
+
Press "y" and enter for the questions that it asks. Should not ask more than 10-20 of them. After this you should be able to reboot back into the Live Ubuntu.
Installing Ubuntu completely on your hard drive for dual booting
----------------------------------------------------------------
-1- Click on the "Install Ubuntu 11.04" link on the Desktop and follow the instructions.
