The first I got my hands on a raspberry pi, I wanted to update its OS to the latest, but the problem is that my RPi is connected to my laptop (using OpenSuse) and I am using SSH to access it (I don’t have access to any displays).

I have bought a VCD movie recently to find that it was not playable on my OpenSUSE, CD2 works fine but not CD1. Then I go back for a replacement disc on the shop and came back to watch it but unfortunately, the problem persist. The problem is that CD1 comtains multiple tracks that most Mediaplayer doesn’t support (tried VLC and Kaffeine). So I started to dive into the problems and found a thread that provides useful information on playing VCD on Linux (Refer to references).

One problem that I encountered is that unlike JDK, GWT does not provide downloads for their API documentation. So an idea come up to me that maybe I should use something like CURL or WGET to get their documentation. So, I googled if that was possible, and found this amazing Linux Journal Tip.

I have spent hours finding solution to this situation and found one particular solution that just works. Tried Mad Scientist’s JNC (Juniper Network Connect) but it didn’t work for some unknown reasons.

A lot of Linux distro is not optimised for laptops, some of them could use up much power if you don’t optimize it. By the end of this guide, you should be able to reduce your power consumption by 3-5 watts, I know it seems not much but it can give my machine 15-30 mins more power. By default, my machine used up more than 24 watts of power, as indicated by powertop. To find out the power usage of your machine:
