I always appreciate coding in standard C++. Desktop Calculator is a application coded in Standard C++. It is a application based on the example 6.1 in the book “The C++ Programming Language”, Third Edition by Bjarne Stroustrup. Desktop Calculator is a GPL software.
Well many times this happens that we want to work with the command prompt. Sometimes we wanna work with many CLI (command line interface). We usually SET the %PATH% variable of system or specific user for this. Things get really worse when we wanna work with more them one version of same Application/Compiler/System. We can’t set the variable as all have similar directory structure and almost same binary/executable names.
Working with command prompt on windows is messy. Working with multiple version of a language/compiler on windows is a trip to hell.
Possible workarounds are:
- Set all the paths and add tags in names of binaries
(stupid. You would have to remember all names or you will have to use some naming convention; still you will keep guessing).
- Create users and set different versions in each user’s paths
(Foolish. Then changing version will be like logging as different user).
- Use a Customized Command Prompt
(Elegant. Developers friendly)
How to Customize Command Prompt.
Create a file Called
YOURSYSTEM-VER-cofig.bat. Where YOURSYSTEM is the name of the system you are using and VER is the version of that specific system like python-2.6-config.bat.
Now put some codes in the file. Like:
Then create a new shortcut Right click on empty space or
File -> New -> Shortcut.
%COMPSPEC% /K "C:pathtoyourfile" in it
Then Rename the shortcut to a proper name.
Then click on Finish. Now Right click on the shortcut.
Select shortcut properties.
We can set the Fonts of the Command prompt.
We can set the color of the command prompt. like BACKGROUND, FOREGROUND.
We can even set the buffer and the screen layout of the shell window.
Now you are ready to enjoy this very good feature.
I recommend you to keep all these files in one folder say with name config-all and with attribute as hidden.

INSAS stands for Indian small arm system. It is an indigenous design of India. It was replacement of Indian military’s standard SLR rifles. It is chambered for standard NATO 5.56×45 mm ammunition. The project started in 1990 SITE by DRDO. It was in production in 2000. It was also exported to Nepal in discounted rates. It initially had some problems with it’s transparent magazines on very low temperature ((Like Siachen)), which were corrected latter.
INSAS project included
- Assault rifle.
- Excalibur ( Advanced carbine with optics )
INSAS is neither an invention nor premium product. It is a perfect design which is inspired by many popular guns, some of them are still in service. It may not be sophisticated but it is found effective in Kargil.
In the image you are viewing INSAS MK-1 with passive night vision optics on top
Some of features of this gun are: “Its AK family design” and Polycrystalline transparent magazines.

Well our old friend Python have a good news to share. Python Enhancement Proposal 3000 (pep 3ooo) states that py3k project will lead to a new version of python which will be no longer compatible to 2.x.
The original pep 3ooo was written in Apr 2006, and since then developers are constantly improving the language.
