Great news, finally ubuntu 10.04 LTS version released, with other based relased for ubuntu such as Kubuntu, Xbuntu, check this release notes and download options for ubuntu.
Sun virtualBox one of the best virtualization applications you can use to run multiple operating system in the same time, but it need some dependencies to get better performance in your operating system whatever the operating system is Ubuntu, Mandriva, Fedora, Centos, …… I am using it now on Ubuntu.
Ubuntu Swap, ” check your operating system Swap ”
really important because it used as same as your installed memory RAM, check this post for ubuntu Swap improvement, just make sure your swap size at least as same as your installed memory RAM.
for system setting you raise to the half memory you already have, for that if raised more than you have the Swap will help to keep you system stable.
also you can use multiple cores if you have multiple core processor. If you have a decent machine you can active full acceleration.
set the display memory depending in you graphics card performance, if you want to get 3d, 2d visualizations it might slow down the virtual machine.
that’s it for now.
After you installed the new version, you maybe will say ” damn where is my bookmark !!!!? ” you forget it with old version usually happen :(
so, Before upgrading to Ubuntu 10.04 LTS which will release on April 29, their are 5 things recommended to do with the distribution you already have. whatever is the distributions is ubuntu 9.10, older versions, or other distribution.
1. Bookmark ” Favorite “ Backup
Most users using Firefox web browser, Google Chrome, Chromium ” based web browser on chrome ” , Opera, …
go to bookmarks then organize bookmarks then you will find export bookmarks. I recommend to export it as HTML file, to easily use it on any other web browser.
also you can export addons if you want. this applications is recommend to backup addons ” FEBE ”
Go to tools, then bookmark manager, then press export it will export it as HTML .
Go to Bookmark, then book mark manager, export it as well.
2. Evolution mail, Thunderbird Backup
If you want to keep your saved messages, you can easily backing it up. go to file, then backup options it will back all messages on archiving file I believe it tar.gz
3. Backup installed packages, and specific file on file system directory.
Many file you may be forget for your webcam, documents files, multimedia files, ….
4. Backup Compiz Fusion
If you are using Compiz fusion make sure you backed up your compiz fusion profile, to easily get same look next time you are going to use compiz.
5. Time to destroy Ubuntu
install any package you didn’t want to try it with this version just for fun. install extra compiz fusion plugin till message comes up telling you ” you have serious kernal error you have to restart ” , share with us what you will do with your own release before installing the new release.
webcam applications for capture photos, videos, multiple photos, and security cameras
One of the most common application located on gnome project, first it was written by google summer code project. really liked effects you can add using cheese ” noir, edge,warp,dice,hulk,….
also you can use this applications for talking multiple photos or videos, customize to specific resolution you want, working in many different distributions you can find many download options for debian based distributions, fedora, ubuntu, mint, …..
2. Camera Monitor
simple tool notify you if your camera is on or off. designed to work on gnome desktop work as well on KDE and Xfce
simply you can install it by terminal
sudo apt-get install cameramonitor
camorama is a program i wrote to learn gtk and v4l. as you can see, i am still learning . it is pretty simple at the moment, and i hope to make it much more complete. i also plan to make it more generic, as i initially wrote it with only my own creative webcam 3 in mind. hopefully it will work with other cameras. i will test on anything i can get my hands on, but that might take a while. right now you can change the video settings using the gui and apply some crappy filters i wrote to mess around with. it runs at a reasonable speed, but i would like to get the fps up as high as possible. still figuring that out. as for requirements, you will need at least gnome 2 and v4l. i haven’t used anything else crazy, and that should do it.
4. Gnome Security Camera “Gspy”
Gspy retrieves images from a video4linux device and processes these into a daily mpeg movie on the disk drive. Each image is recorded with a time stamp to insure accurate real world correlation. Special motion detection algorithms are used to reduce the size of the daily movies by eliminating pictures with similar content as well as the normal compression obtained via the mpeg process. The result is a time lapse video per day with nonlinear time compression using only the images of interest. This program will only run on Linux machines which support a video4linux-device in 640×480 capture size. This software has been tested with the 2.4.0-test1 kernel, 2.4.0-test4 and the 2.2.16 kernel with the usb backport patch. You should have the Berkeley MPEG Tools installed if you wish to generate the MPEG files. Gspy can be used without the MPEG tools, as it will fill a directory with jpg images that can be processed or viewed at a later time. Versions from 0.1.6 include a user defined command that is executed on each alarm. This command string can include a token(s) “%f%” that will get replaced with the alarm picture filename. Typical uses would be to copy the alarm picture to a remote site using ftp or scp, email the picture to someone, play a sound annoucement… “Step away from the keyboard!”, turn on lights using a parallel port or X10 interface, or ???. Have FUN
My favorite webcam application for KDE, support many webcams, able to capture photos, videos, multiple photos. you can easily share your photos and videos directly from the application to facebook and twitter.
that’s it for now.

Common applications installed using synaptic package manager already installed by referring from default repositories added on ubuntu 9.10 or any other version it’s the same way to add extra repositories for other distributions such as ubuntu 10.04 LTS beta 1
Default repositories on ubuntu monitored by ubuntu community, so in this post i will show you how to add extra repositories for ubuntu 9.10 and 10.04 LTS beta 1 as well.
1. Adding repositories
you can get access to it using:
a. synaptic package manger
System menu —> Administration —> Synaptic —> Settings —> Repositories
b. System menu —> Administration —> Software Sources
Common repositories already added on software sources by ubuntu and kubuntu. some application need to add extra repositories to be able to install it in your machine, will use this as example
deb http://ppa.launchpad.net/moovida-packagers/ppa/ubuntu karmic main
access the software sources, will ask you for root password then go to other software and press add button and paste the apt line like this one up there
If you want to backup all repositories you already have type this command on terminal
sudo cp -i /etc/apt/sources.list /etc/apt/sources.list_backup
This will copy you repositories list to this folder “./etc/apt/ ” with name called sources.list_backup
2. adding repositories key
some application need repositories key to get rid of so warning massages during the installations
so you will find more instructions on the website for installing this package and it will mention repositories key you can add it directly from the terminal.
That’s it for now.
