Xubuntu 12.04

Nov. 8, 2012 marks the day I switched to Xubuntu. Simpler than Ubuntu's Unity, and a bit prettier than Lubuntu.

Messengers running on Android (2.3) and memory footprint

1. Catfiz - running in memory = 9.2MB, installed size = 3.12MB
2. imo - running 16MB, installed 8.65MB
3. nimbuzz - running 20mb (!) yuck.
4. fb messenger - 11MB memory; 10.55MB file size
5. kik - 18MB memory; 3.06MB file size

Openproj

MS Project open source alternative for Linux. This works for Ubuntu 11.04

wget http://nchc.dl.sourceforge.net/sourceforge/openproj/openproj_1.4-2.deb && sudo dpkg -i openproj_1.4-2.deb

Update 3 Nov. 2012
Installing in Ubuntu 12.04 (Xubuntu, to be exact), produced dependencies issues, even though I do distinctly remember putting in the xubuntu-restricted-extras package during 12.04 installation.

These are the additional packages needing to be installed:

ca-certificates-java icedtea-7-jre-jamvm java-common libatk-wrapper-java libatk-wrapper-java-jni openjdk-7-jre openjdk-7-jre-headless openjdk-7-jre-lib ttf-dejavu-extra tzdata-java

So I try fixing it in the terminal:

sudo apt-get -f install

But it takes a long time (shame on my broadband provider!) I had to try also changing the server for the repos (in Synaptic) several times, then eventually going back to my country's server.
After numerous alt-c on the terminal, and repeating this:

sudo apt-get install ca-certificates-java icedtea-7-jre-jamvm java-common libatk-wrapper-java libatk-wrapper-java-jni openjdk-7-jre openjdk-7-jre-headless openjdk-7-jre-lib ttf-dejavu-extra tzdata-java

I finally got all the packages downloaded and installed. After which, going to Synaptic and with the filter set to Broken packages, completely removed OpenProj, and reinstalled with the wget... from my original post.
Running it finally caused an error:

To fix this error, I modified the ~/.openproj/run.conf file by changing the line:

JAVA_OPTS="-Xms128m -Xmx768m"

to:

JAVA_OPTS="-Djava.vendor=Sun -Xms128m -Xmx768m"

and now it works. Got this tip (somewhat, didn't follow completely his instructions) here.
