Floating point math operations in bash
When writing scripts in bash, sometimes we need to work with basic math functions. Like the trigonometric functions, square root, cube root, logarithms. Bash does not support floating point operations. This is where the problem is encountered, and we cannot write a math function of our own. There must be a way to do this, and yes. Bash supports redirections so we can feed the floating point computations and the math functions into some other program’s input who understands it. The program which can be used is the bc, which is an arbitrary precision calculator language. bc can do floating point operations, and also can do basic math functions. With bash and bc we can do the above. Continue reading to know how.
Pause and Break the Key
Yesterday in college I found an IBM keyboard with a broken Pause/Break key. Now why is this particular key broken, when It is rarely used? Almost instantly I realized, that the answer was written on the key, a previous user might have just followed what was written on the key.
CDlinux
In the world of minimalist GNU/Linux distributions, we introduce you to CDlinux, which originated in the People’s Republic of China, in 1999. Four years later, in 2003, the first public release, version 0.4.2, came out. The latest version 0.9.5, which was released on December 02, 2009, is a mere 62 MB.
CDlinux, or Compact Distro Linux, was primarily intended for systems administrators as a systems rescue tool. But it can also be used as a bare minimum portable desktop OS and as a customisable OS base. The default desktop environment is Xfce (currently 4.6.1) with the Thunar file manager, thus ensuring CDlinux cuts out the fat. The whole distro loads on the RAM, so the access is rapid. The official edition’s RAM requirement is only 64 MB. CDlinux is capable of booting from CD/DVD and HDD. It also supports USB and IEEE1394 interfaces for booting.

CD Tray Open/Close infinite loop
Just feel the annoyance and irritation when the CD tray of your computer opens and closes, opens and closes, again and again, again and again, and does not stop until you shut down the computer. We will be writing a tiny shell script with which we would do the above stuff. Although this is very cruel if you apply this to some one, then please be sure to fix it before he/she shoots you with a 50 caliber rifle. So keep on reading to know how to make the simple script to make an infinite CD-ROM tray open close loop in GNU+Linux
Beginners Guide to GCC
GCC is the default compiler in the GNU+Linux systems, and is used to compile small applications, big softwares, and the kernel. Often beginners are overwhelmed with the amount of information provided in the gcc manual. This tutorial highlights the most useful commands and describes how to use them, how to read warnings and errors from the compiler output and compile the C Language sourcecodes with gcc. This tutorial does not cover advanced options and topics, in depth details are avoided. This tutorial will give the basic idea, and after reading this i hope that the manual pages would be easier to read.
GIMP Glassy Text Wallpaper
Playing with GIMP is never boring, every time you do some experiment you come to know of some cool effect. The best part is the filters, which if applied properly, can produce jaw dropping effects. While experimenting with GIMP i came to know that how easily glassy texts could be created with gimp. Although i am not a image maker, or a GIMP expert, i will try my best to describe this process. I have broken down this process in some sections, each one describing how to make each image effect component. Let’s start.
Copying by Writing is Copyright making FOSS illegal !!
A new teacher was taking her first class. She was skimming through the points of Software Engineering. When discussing about software cost she told that Software is costly. One student suggested and told that, what about Free Software. She corrected him by telling that the software we use are Pirated and distributed in “Copywrited” discs and illegal , so we do not have to pay for these, and thus it is Free. Students got confused. Another guy asked , if the software is in a “Copyrighted” disc then why it is illegal. Then she tried to describe that what is original software and a licence is provided with it. After some more confusion a student ultimately asked — “What is Copyright” . The answer from the teacher was something like this when translated: “After a legal original software copy is bought, we copy it and write it in a CD , and so we call that a “Copywrited” software which is distributed for “Free” .”
Note: When reading please note the “Copywrite” and “Copyright” spelling

All Combinations Without Repetitions
Problem : To generate all Combinations of a set of distinct elements
Before we start discussing about the implementation we will go through the basic definitions of Combinations. Then we discuss the method to generate all the Combinations with examples and descriptions. Then the source code to implement the method will be presented. Continue reading.
