# I just installed SanDisk 6Gig/s SSD in my Sony VAIO Laptop today. | |
# I also installed Xubuntu 13.04 on it as well. I have been | |
# using Ubuntu from almost a year now. I was actually kind of | |
# getting tired of Ubuntu, it was causing a lot of issues. And yes I | |
# am well aware of the fact that Xubuntu is technically Ubuntu. | |
# Anyways that's not why I am writing this gist. I am just creating | |
# this gist so I can have a reference to my bash aliases file | |
# and so that other's can use it as an example as well. | |
# Add more if you have more simple useful aliases. | |
