FlickerFs

Flickrfs is a virtual filesystem which mounts on your linux machine like any other partition. Once mounted, it retrieves information about your photos hosted on your flickr account, and shows them as files. You can now easily copy photos from your local machine to this mount, and it will automatically upload them to your flickr account. Similary, you can copy the files from your mount to your local machine, and it will download your images from flickr.

Manish has all the information about installing FlickerFS under Linux and Ubuntu computer.

This tutorial explains GDM (GNOME Display Manager) modification to support user verification through keystroke-dynamics processing. Modified GDM allows only you to login. If you go ahead and tell your password to a friend. They still won't be able to log in using GDM without knowing the precise method of typing required when entering your user name.

You can create and store a one-way encrypted hash of your keystroke patterns when entering your user name. Add code to GDM to read current keystroke patterns and permit a user to log in when the characteristics are a match.

Many commercial products today provide two-factor authentication on Linux systems. These technologies generally require the purchase of additional hardware and create a closed implementation unsuitable for many environments. The code and processes presented here allow you to implement a low-cost authentication-input system based on the characteristics of how a user types his password into the GDM. Moving beyond examples and into implementation, the modifications to GDM presented here allow you to enhance the security of your computer.

This is an excellent backup utility for new Linux user.

Apple's Time Machine is a great feature in their OS, and Linux has almost all of the required technology already built in to recreate it. This is a simple GUI to make it easy to use.

Time Machine, like many backup utilities, creates incremental backups of files which can be restored at a later date. It also supports limited restoration of files within applications that are specifically programmed to use Time Machine's functionality.

From the article:

Changes are part of Nature so as with Technology, though this cannot be True for Windows and Mac cause the life cycle of a single Version is too much which is not the case with Linux.

Compiz brings to life a variety of visual effects that make the Linux desktop easier to use, more powerful and intuitive, and more accessible for users with special needs. It is an OpenGL-based compositing and window-manager. Compiz is the original compositing window manager from Novell's XGL project. It is developed by David Reveman and community.

Compiz is one of the first compositing window managers for the X Window System that uses 3D graphics hardware to create fast compositing desktop effects for window management.

By default Compiz configuration settings manager is not installed under Ubuntu Linux 7.10. So first install compiz manager:
$ sudo apt-get install compizconfig-settings-manager

Please note that compiz only worked with 3D hardware which was supported by Xgl. Most NVIDIA and ATI graphics cards are known to work with Compiz on Xgl. On board Intel card (Intel GMA) also reported working with compiz.
