KDE stands for K Desktop Environment and this is free software that provides an easy to use and application rich desktop environment.  KDE’s origins are rooted in Linux but the latest release brings with it support for both Windows and Mac.

This means to a limited extent we can get a KDE experience on windows. The KDE environment for Windows is not exactly the same as windows, rather it consists of certain applications of KDE. It uses KDE shell but with far limited functionality , it one can’t think of replacing the windows environment with KDE environment.

Different applications in KDE are available in separate packages , which share dependencies. It saves time and effort as two applications which may use some similar functionalities , the common stuff is installed only once.

Installation

The latest KDE4  for windows can be downloaded and installed using a installer from http://windows.kde.org/

After downloading the installer follow the given steps.

1. Install from internet option is already selected. If not select this option and click next.

6. Select a mirror and download the packages.

7. Pick the latest release.

8. Choose and select application which you wish to keep.

9. The installer then downloads the necessary packages.

10. Now the actual installation begins.

11. Thats it! Installation is done and KDE4 application can be launched from Windows start menu.

After installation all KDE4 applications will be available in programs menu folder. Now you can start using KDE4 on windows.

Here are a few useful Linux Keyboard shortcuts :

1. Arrow up or Arrow down : The up pr down key when used in a terminal windows allows to cycle through history the commands used in the terminal windows. Using this shortcut you don’t have to retype the commands and also you don’t need to remember what commands you issued earlier in the session.

2. Alt + Arrow Key : In Linux pager allows you to have multiple desktops at one time. Instead of moving the mouse to the window to switch between different desktops , you can use Alt + Arrow keys to switch between the different desktops.This works in all desktop environments and window managers.

3. Alt + Tab : This shortcut allows you to cycle through different windows and stop on the window which you want to open. Instead of using mouse to click on the window you want to open , you can use this shortcut to good effect. This works in most dektop environments.

4. Ctrl + Alt + Del : If you are stuck and everything else fails to work , you can use this  shortcut to immediately restart your computer . Though you will loose all your unsaved data , so you must use this command carefully.

8. Ctrl + R : This is a useful command research option. When you use this shortcut , you are prompted to enter a character or a string of characters. You’ll get all the command you may have used earlier with the search character in it or the combination of search characters. Once the search result appears on the screen, you can press enter to execute the command.

The H1 has a brilliant 3.5” WVGA AMOLED displaywith a host of other features which makes it an interesting option to look at. The features of fast HSDPA at 7.2 mbps and Wifi connectivity allow easy connectivity to net on the go. The special interface provides quick and easy access to social networking sites. Some of the other features include 5 MP camera, GPRS, GPS, Push email, HD video capability and media player with support of various media codecs. It has a 16 Gb of internal memory and slot for micro Sd card ( 16 Gb) to allow user to store different multimedia files.

The other set M1 has HSDPA, 3.2 TFT Touchscreen Display, Push email, 3 M.P. Camera and 1 Gb of rxpandable memory. This set would be available in 3 colour variants.

The advantages of a Linux based OS are also there. The LiMo is more flexible , broader focus than other exisitng operating systems. All the advantages of linux also apply here. It would be interesting to see how this Os puts up against the existing market leaders. Is this going to intensify the race to best OS or will the exisitng OS still rule the roost ? Another question is how will samsung justify its use of different OS in different phones and convince users that both are worth spending on.

Have fun using one of the very good Antivirus on your Ubuntu machine.

Just to see how it works I tried installing AVG anti-virus on my machine on Ubuntu and it looks good. Installation is pretty easy and the interface is pretty intuitive for using. Let’s see how to get it working on Ubuntu.

Homepage

http://avg.com

Installation

1. Download free AVG version for Linux from here. I chose the deb version for my ubuntu.

2. Double click the downloaded deb file, enter your sudo password and click install.

This should install AVG on your Ubuntu machine. In order to start/launch AVG, you can go to Applications > Accessories > AVG for Linux Workstations

Although you can run the test without using super privilege.

In order to update the version you’ll have to start AVG with super privileges. To do so, open terminal and type the following:

sudo avggui

Enter your password and you are good to update AVG.

But before we go into the details of installation let’s see what a Mind Mapping software is. Following a description from Wikipedia:

A mind map is a diagram used to represent words, ideas, tasks, or other items linked to and arranged radially around a central key word or idea. Mind maps are used to generate, visualize, structure, and classify ideas, and as an aid in study, organization, problem solving, decision making, and writing.

The elements of a given mind map are arranged intuitively according to the importance of the concepts, and are classified into groupings, branches, or areas, with the goal of representing semantic or other connections between portions of information. Mind maps may also aid recall of existing memories.

http://live.gnome.org/Tasque

Description

Tasque is a simple task management app (TODO list) for the Linux Desktop. “Tasque” is pronounced just like “Task.”

Demo

A lot of people do not know what these are so let me define the 3 terms I used.

Window Decorator

Window decorations are provided by window managers to improve the usability of a multi-windowed desktop. They typically consist of a title bar along the top of each window and a minimal border around the other three sides, although this can often be varied upon if the user wishes.

In the predominant layout for modern window decorations, the top bar contains a title and buttons which perform windowing-related actions such as minimizing, maximizing and closing . The border exists primarily to allow the user to resize the window.

GTK Window decorator

Gtk-window-decorator is the default window decorator of Ubuntu.

Emerald

Emerald takes the graphic experience in Linux to a new level. It brings all the power of window decorators like transparency and vivid colors.

Emerald Window Decorator (formerly known as cgwd, which stands for Compiz Generic Window Decorator) is a window decorator for the Compiz compositing window manager written by Quinnstorm.

How to install Emerald in Ubuntu 8.10 (Intrepid Ibex)

Installing emerald in Intrepid Ibex is very easy. Start a terminal window by going to Applications > Accessories > Terminal. In the terminal window type the following one by one:

sudo apt-get update

sudo apt-get install emerald

This should install emerald on your Ubuntu machine.

Starting Emerald in Ubuntu

Initiate the Run Prompt by clicking ALT+f2. In the Run prompt type the following to start Emerald.

emerald --replace

This should change your window decorator to Emerald. However, this will only make your window decorator to emerald only for the existing session. If you want to make it your default you’ll have to set it up to launch at startup.

How to start emerald at startup in Ubuntu

Go to System > Preferences > Sessions > Startup Programs and click Add and enter the following details:

This should start emerald window decorator at startup of Ubuntu.

Getting back to GTK Window Manager

However, if you want to get rid of emerald window decorator, at the Run prompt, type

gtk-window-decorator --replace

This should replace emerald to gtk window decorator. Also, delete the entry of emerald from startup if you don’t want it to be your default window manager.
