How to Rip Audio CD in Linux
As MP3 players and mobile devices become very common, more and more people are beginning to convert their audio CD collection to music files so they will listen to them while on the move. In Windows and Mac, the conversion can be done automatically with Windows Media Player or iTunes. What about Linux? Let’s take a look.

[Snippet] Ubntu: Backup Your Applications Easily With A Single Command
Installing applications in Ubuntu is as easy as the app store in iPhone. Hit the Ubuntu Software Center, find the application you want and click Install. Due to this convenience, most of the time, you won’t need to backup the applications itself.
However, there are times when you want to restore the newly formatted machine to the original state and you find it a chores to manually install all the applications again. This is when the backup is useful.
When we say “backup” in this case, we don’t really mean backing up the actual application. What we are going to do is to export the list of all your installed app onto a text file. Next time, we can just get the system to reinstall the apps listed in the text file.

Backing up your Apps
(Optional) To list all your installed applications, open a terminal and type:
sudo dpkg --list
To backup your list of applications to a text file:
sudo dpkg --get-selections > app-backup-list.txt
This will create a text file of the name “app-backup-list.txt” in your Home folder.
How to Use KDE Plasma Activities
The concept of activities is a new feature introduced with KDE 4. In the old desktop model of KDE 3, the desktop was a program called “kdesktop”, which gave users the ability to have a number of virtual desktops. Although other tools like Superkaramba could be used to add more features, the essential KDE desktop ended there.
When activities were introduced into KDE 4, they did not make much sense in isolation. In addition to having virtual desktops, there were activities, which the user could create and configure to have different wallpapers and different widgets. Much of the virtual desktop functionality of KDE 3 was absent and not directly connected to Plasma activities.
With the release of KDE 4.5, Plasma has reached a much higher level of maturity, and activities can now be integrated with virtual desktops, dual monitor screens, and with the Dashboard feature.

Review of Qimo: Linux for Kids
We’ve talked about Linux software for kids a few times here at MakeTechEasier, but so far we’ve never actually sat down to take a closer look at whole distributions intended for children. Many people are familiar with Edubuntu, the Ubuntu spinoff intended for school and other educational institutions, but you may not know much about Qimo. Unlike Edubuntu, which is designed for a client-server network model, Qimo is intended for a sole desktop user – in this case children 3 years old and up. It uses a customized version of the XFCE desktop, with large icons and simple menus, to make it easy to navigate. Included are many of the top titles in kids software for Linux, such as GCompris and TuxPaint. Today we’ll take a look at what Qimo has to offer, and submit it to the ultimate test: a real live toddler.

How to Make Incremental Backups With Rsync
Backing up your information is very important to you, or at least it should be. One of my college professors once told me, “It is not a question of if your hard drive will crash; it is when your hard drive will crash.”
Rsync is a tool that allows you to keep two distinct directories in sync, either locally (two locations on the same machine, including attached devices) or remotely (local computer to server or even server to backup server). It is free and open source software and runs on Linux and most other Unix-like operating systems, including FreeBSD and Mac OS X.
Furthermore, those who prefer not to get their fingers dirty on the command line can use Grsync, a graphical frontend for rsync, available in most Linux distribution repositories.

Peppermint Ice is like Chrome OS without sacrificing local apps
Plenty of people scoffed at the original Google announcement about Chrome OS. It's just another minimalist Linux distro, they said -- but that's actually not quite true. Unlike most lightweight Linux distributions, there won't be any traditional local apps apart from the Chrome browser.
If you'd like a Chrome OS-like experience without having to give up apps like Transmission, VLC, or DropBox? Take a look at the new release from the developers behind Peppermint.
Dubbed Peppermint Ice, the new spin replaces Firefox with Chromium and includes the same selection of web app shortcuts (Facebook, Seesmic, Google Docs, Hulu, Pandora, etc.) and local apps (like DropBox, Tranmission, and XChat). Want to add your own web app shortcuts? It's a snap using the built in Ice tool. And since Peppermint is derived from Linux Mint, apt-get is available via the terminal -- meaning you can install boatloads of other apps if you want to.

Kendall Weaver, who heads up Peppermint development, told me that on his Core2 notebook with an OCZ Vertex SSD Peppermint Ice boots up in about 6 seconds. That's definitely speedy enough to compete with just about any "instant-on" OS I've tried out. Even on my admittedly poorly-configured, Atom-powered Gateway netbook Peppermint boots in 10 seconds... Nice!
Peppermint is a solid Linux distribution for people who just want to surf but don't want to give up the flexibility which Linux distros typically provide. The interface is clean and simple, and should be familiar to anyone who's ever used Windows XP. Hey, if my 5-year-old can jump in and find his YouTube favorites on Peppermint, the learning curve can't be too steep (if it even exists).
Good news if you're a Firefox fan: Kendall also informed me that Peppermint One will be switching to Firefox 4.0 when the second beta arrives. The switch will provide a welcome performance boost, though you might have to deal with some broken extensions temporarily -- although if you're installing Firefox betas you're probably used to that by now...

Snippet: How to Make Google Chrome As The Default Browser in Ubuntu

Even though Google Chrome is faster and lesser prone to crash, it is still NOT the default browser in Ubuntu. At least until Ubuntu Lucid, Firefox still reign in Linux arena.
Now, if you have installed Google Chrome and intend to use it as the default browser, won’t it be great if you can set it as the default application for all web links so that your Firefox won’t pop up annoyingly?
In Ubuntu Lucid, you can easily change the default application by going to System -> Preferences -> Preferred Applications. Under the “Internet” tab and “Web Browser” section, select “Google Chrome” in the dropdown list.

Close the window. That’s it.
In situations where you can’t find Google Chrome in the dropdown option (and you are sure that you have installed it), choose custom from the dropdown list and enter
