Ubuntu 11.04 battery saving

Recently battery life on my laptop (acer aspire 3820TG) has reduced quite heavily. I could not pin point any specific reason, but I thought that it has decreased significantly after I had brought ubuntu one into use. Without spending too much time on why the battery life reduced, I started googling tips for saving battery life on ubuntu. The following post gave very relevant tips, with very detailed explanation.

So, I decided to activate the laptop-mode. In fact, doing so has apparently been even more easy than what was described in the above ubuntu forums post. All I had to do was to install laptop-mode-tools.

sudo apt-get install laptop-mode-tools

In fact, the laptop-mode-tools actually came out of box with quite sensible settings pre-configured, so I didn't have to do any extra work to get the laptop-mode working! The only thing I did was to install powertop and check that powertop had no more suggestions when I was running on battery! (NOTE: powertop did have some suggestions when I was running on AC, but that is because the power saving settings were configured to be activated on battery).

Besides, this, I gathered from other sources another nice little software called jupiter. I installed that using the following commands.

sudo add-apt-repository ppa:webupd8team/jupiter
sudo apt-get update
sudo apt-get install jupiter

And... yeeee... now the battery is working great!!

Set up for analysing genome-scale metabolic models on ubuntu

I wanted to start analysing genome-scale metabolic models. I am interested in metabolic modelling to study human diseases. At least as of now, my idea is to use R for the analysis. This post describes all the technical set-up that I am doing on my ubuntu 10.04 LTS machine in order to eventually start working with these models. As I am interested in human metabolic network, my model of interest is the reconstructed human metabolic model, recon 2. I googled to see where I can download it from. It has a web site http://humanmetabolism.org/. But the model is available for download from the supplementary material of this paper . There was a zip file that contained many files which I interpret as the generic human model and cell specific models for a variety of cell types. I first wanted to see the contents of these files with my eyes. I know that I could open these files with any text editor, but I also knew that there is something called SBML editor which is specifically designed fo...

Setting up R packages for CBM of genome-scale metabolic models on Ubuntu 13.10

Long ago, I posted here the steps involved in setting up R packages for performing constraint based modelling (CBM) of genome scale metabolic models. It was Ubuntu 10.04 LTS back then. Now, I am trying to reproduce the same set-up on Ubuntu 13.10. As a quick summary, we need the following R packages: "sybil", "sybilSBML", and "glpkAPI". The "sybilSBML" R package requires the Bioconductor package "rsbml" which requires "libsbml" library, which in turn depends on "swig". The "glpkAPI" is an R wrapper for glpk library which is the optimization engine. I have been able to install all these packages by executing the following steps. 1. Install swig from ubuntu repositories. sudo apt-get install swig 2. Install python-dev from ubuntu repositories. sudo apt-get install python-dev 3. Install openjdk from ubuntu repositories. sudo apt-get install openjdk-7-jdk 4. Install libxml2 and libxml2-d...

ZyXEL VMG3326 D20A ADSL modem Linux wireless network problem

I bought 10Mbps ADSL network connection from Saunalahti . It works all perfect except for this little glitch I had with it: from my Linux Mint Debian Edition (LMDE) or Ubuntu machine, I could not get the wireless network. While a windows machine and two android phones can access the wifi signals from the modem, the Linux machines can't even see the SSID of my network. In the beginning when I had just setup the modem I could access the wireless network from my LMDE machine. I started noticing the problem with the network, when I turned off my ADSL modem one day and in the evening turned it on. While all other machines got the connection as soon as the modem was up, my Linux machine could not detect the signal. After a little bit of messing around, I concluded that, for Linux to receive the wireless signal without a problem and to get the connection after the modem restarts, I need to follow the following protocol. I need to turn the wifi off on the modem by pressing a blue butto...
