DOSBox installation

For Ubuntu users (using repository)
Open the terminal and type in the following commands to download and install DOSbox in Ubuntu
sudo apt-get update
sudo apt-get install dosbox
You will find it installed under Applications_Menu->Games->DOSBox Emulator

For other GNU/Linux users
Download DOSbox from here.
Open terminal and cd to the directory containing the downloaded tar.gz file. Type in the following commands to build and install :
tar -xzvf dosbox-0.74.tar.gz
cd dosbox-0.74
./configure
make
Check the src subdir for the binary.

For Windows users
Download DOSbox from here.
Run the downloaded .exe file and install it like any other software.

Now that you’ve installed DOSBox, you’ll be able to run any 16bit or 32bit DOS executable inside it.

Download the 8086 MASM Assembler from here. The zip file contains the following files :
masm.exe, tasm.exe, link.exe, bin2hex.exe, exe2bin.exe, td.exe, edit.com and debug.exe

Windows users extract the .zip file into C:\ so that the path C:\8086 contains all the above mentioned files. GNU/Linux users can extract it and place it in say /home/prashanth/8086

Launch DOSBox and type the following commands :
For Linux users :
mount c /home/prashanth/8086
c:
For Windows :
mount c c:\8086
c:

DOSBox running in Ubuntu

Now the contents of the folder /home/prashanth/8086 or c:\8086 is mounted as c: drive inside the DOS emulator. You can assemble programs inside DOSBox as you do in your Microprocessor Lab under Windows XP; i.e your usual sequence of commands -
edit file.asm
masm file.asm
link file
debug file.exe

When you are done, type exit to quit DOSBox.

P.S : For GNU/Linux users, there’s an alternative assembler known as the NASM. NASM is considered to be one of the most popular assemblers for GNU/Linux.

How to change your DNS
Changing DNS server settings

1. Using Add2Run utility
Let’s start with the most simple way to launch applications from Run. Add2Run developed by Jitendra Bangani is a tiny standalone portable utility designed just to do this.

1. Download Add2Run (250 KB) and run the application.
2. Select the target application or program that you want to launch.
3. Select an alias name. You can launch the selected application from Run by typing this name. For example, in the following screenshot, whenever I type hex in Run and hit Enter, a Hex Editor application launches.


Add2Run

2. Creating an alias in Registry
This method involves creating a new alias by creating a new key in Windows Registry. This is the usual or the ‘official’ way.
1. Start the registry editor (regedit.exe)
2. Move to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\App Paths
3. From the Edit menu select New – Key
4. Enter the name of the alias, e.g. hex.exe (.exe part is necessary)
5. Move to the new key and double click on the (Default) value (it is blank by default)
6. Set its value as the full file path of the program you want to launch, e.g. E:\PF\Hex Editor\XVI32.exe (path). Click OK
7. Close the registry editor

Note : To launch a programs from Command Prompt, just use the following syntax :
start aliasname
For example, start hex

3. Using Environment Variables
This method involves creating an environment variable. You can use this method to launch any file or directory. But, unlike the above two methods, from run, you need to enclose the alias name between % symbols. For example %AppData% is an environment variable used to access Application Data directory of the current user profile.

1. Right click on My Computer >> Properties
   ( or use the shortcut [Windows button] + [Pause/Break] ) to open System Properties.
   
2. Under the Advanced tab, click on Environment Variables.
3. Now you will see a list of variables that are already assigned. Click on New.
   
4. Type in an alias name in the Variable name field.
5. Type the full path of the file/directory you want to launch Variable value field.
   
6. Click OK.

For example, if you type hex as Variable name, then you can launch the target application by typing %hex% in the Run dialog box.

Here are some of it’s features :

• Drag and Drop GIF Images
• Set Frame Delay Time
• Automatic Interlacing
• Automatic Transparency Detection

Convert images to GIF
If you have source images saved in JPEG/PNG/BMP etc, you can convert it to GIF using any photo editing tool or image converter. You can also use the “Save As” in Paint to convert images into GIF. These individual files serve as GIF frames. It is recommended that the images have same dimensions.

UnFREEz

3 simple steps to create your GIF animation

1. Drag and drop GIF files to UnFREEz window. Please remember that your frames must already be saved in GIF format (UnFREEz does no converting). The images must have same dimensions to get good result. The order of input files will determine the order of frames in the final animated GIF.
2. Specify a ‘Frame Delay time’ which sets the time between frames. This time is in centiseconds i.e one hundredth of a second. Also you have the option to loop the animation or just play once and then stop.
3. Now, you can hit the ‘Make Animated GIF‘ and save the animation. If you think the animation that you created is too fast or too slow, just change the frame delay time accordingly.

Here is a sample GIF created from 5 individual frames using UnFREEz :

The site also provides devotional songs, classical songs, folk songs, discourses, hari kathe, yakshagana etc !


KannadaAudio.com

But the site does not allow download. The song is streamed to your Real Player. In this article I am gonna show you how to download songs for free and play it on your computer using Real Player. Here’s how to do it.

• Go to KannadaAudio.com. Film names are arranged in alphabetical order. Select a movie name to see a list of songs.
• Right click on a song name and select Save Link As option. Save the file and do NOT open it with Real Player. It’s barely a few bytes in size and has the file extension .ram
• Now open the saved file using any text editor like Notepad. You will see URL of the song.
• Copy the desired song URL to address bar of your browser and hit Enter.
• You will be prompted to save the file or play it using Real Player. Save the file with any name. The file will have .rm file extension.
• Play the saved file with Real Player and voila you are done.

Update : sensongs.com seems to have Kannada mp3 songs for direct download. Use that instead.

Enjoy
