It aims to provide an easy way to carry out admin tasks on your computer, such as creating and editing the partitions of the hard disk. It contains a lot of system utilities (parted, partimage, fstools, ...) and basic tools (editors, midnight commander, network tools). It is very easy to use: just boot the CDROM.

tutorial - Bluetooth -- Leave it - it's locked, come back - it's back too...

BlueProximity is software helps you add a little more security to your desktop. It does so by detecting one of your bluetooth devices, most likely your mobile phone, and keeping track of its distance. If you move away from your computer and the distance is above a certain level (no measurement in meters is possible) for a given time, it automatically locks your desktop (or starts any other shell command you want).

Once away your computer awaits its master back - if you are nearer than a given level for a set time your computer unlocks magically without any interaction (or starts any other shell command you want).

tutorial - A powerful, speedy, and sexy remote control for your Desktop - GNOME Do

The typical computer user interacts with a number of different resources and programs on her computer, all of which are accessed by disparate means, including menus, location bars, icons, shortcut keys, etc. We plan to consolidate these interfaces by creating an application that indexes items in the user's desktop environment (documents, contacts, bookmarks, applications, multimedia, etc.) and lets the user search through these items and manipulate these items with commonly performed actions (open, run, email, chat, etc.).

GNOME Do allows you to quickly search for many items present in your GNOME desktop environment (applications, Evolution contacts, Firefox bookmarks, files, artists and albums in Rhythmbox, Pidgin buddies, etc.) and perform commonly used actions on those items (Run, Open, Email, Chat, Play, etc.). GNOME Do is inspired by Quicksilver and GNOME Launch Box.

GNOME Do is not a search tool. If you know what you're looking for and what you want to do with it, Do will help you do it quickly.

GNOME Do is not only for GNOME. Although it was created by a GNOME lover, Do runs on KDE and other common environments.

tutorial - Monitor Web page changes

Specto is a OpenSource WebPage update/monitoring program - it saves you time and keeps you updated by automatically checking web pages (static or dynamic)to see if they have changed also helps to check it at time when someone is trying to change your page.

You can configure Specto to monitor changes to wiki pages, blog posts, forum threads, your email inbox, and even files and folders on your own system. An unobtrusive pop-up from its system tray icon informs you of all changes, so you don't have to hop around looking for updates.

You can install it from the compressed tarball if you want the most recent release. First explode the tarball with the tar zxvf specto-0.2.2.tar.gz command. Next, browse into the specto-0.2.2/ directory. You don't have to install Specto to begin using it; the command ./launch.sh launches Specto. But Fedora and Ubuntu users can respectively use the su -c "python setup.py install" or sudo python setup.py install command to install Specto.

tutorial - Reiser FS is dead (RIP)

Yesterday, the Open Source community took an emotional hit when veteran Linux programmer Hans Reiser was convicted of first degree murder in the suspicious disappearing of his wife, Nina. While I won’t go into the details of the case, as this has been covered extensively in the press, I would like to talk a little bit about how this verdict will impact the technology in play for file system dominance in our favorite Open Source operating system, Linux.

Suse and Debian use ReiserFS version 3, a stable and proven version of the code that has been sitting mostly fallow for some time, and is maintained with bug and security fixes on a best effort basis.

From the SuSE and Debian perspective, this is an obviously unacceptable state of affairs. The OpenSuSE project has already moved its distribution to use the ext3 file system

Reiser found guilty of first degree murder

and Linux, and in principle could be configured to manage almost any software.

anyRemote could be used with:
* bluetooth connection with java client if cell phone is JSR82 compatible
* Wi-Fi connection with java client if phone supports Wi-Fi
* IR connection with java client if java realization in phone supports access to IR port
* ordinary TCP/IP connection with java client, if PC is connectable from internet
* bluetooth, infrared or cable connection using AT "modem" commands

* web interface
* it supports some of IR remotes supplied with TV tuner cards (like LIRC)
* it has limited support for Bemused clients
