Fuduntu 2013.1

Lee Ward has announced the release of Fuduntu 2013.1, a new build of the rolling-release distribution which features GNOME 2 as its default desktop: "Fuduntu 2013.1 released. For those with hardware that use proprietary drivers, one of the first things that will be noticed after install is Jockey, the program that checks hardware and presents the user with the proprietary driver(s) needed. An example of this would be graphics drivers for NVIDIA and AMD cards. Since we're on the topic of installation, we would like to point out that, by default, sudo is now enabled for all new installs. Another noticeable thing will be the new dock. Unfortunately, AWN is no longer being maintained upstream and there are several bugs that have been left open. In addition, AWN will no longer build against the latest glib. After much discussion, the team decided to migrate to the Cairo dock. This is now installed by default." Read the detailed release announcement for a complete list of new features. Download from SourceForge: Fuduntu-2013.1-x86_64-LiveDVD.iso (959MB, SHA1, torrent).

Easily Password Protect Your Files/Folders in Ubuntu/Linux Mint

In this tutorial, we will explain for newbies how to easily password protect files or folders in Ubuntu/Linux Mint systems. You don't have to use any third-party software, we will just use the archive manager to compress the file or folder and lock it with a password so that you disallow unauthorized users from copying your contents.

Getting Started

Right click on the file(s) or folder(s) and select Compress:

In the window that will appear, select a compression format (7z, zip, tar, etc.), then click Other Options:

Enter any password of your choice, check on "Encrypt the file list too", then click Create:

You have now compressed and password-protected your file/folder. No user can now extract the archive file unless he/she provides the correct password:

More Advanced Options

If you want to prevent other users from deleting or moving the password-protected archive file you have just created, open the terminal and cd to where it is stored, then run this command:

sudo  chattr +i file-name.ext

To undo this, enter this command:

sudo  chattr -i file-name.ext
