Think twice before buy A Laptop or A PC

When I went to buy a laptop these days, I identified that there is a serious issue with some Laptops and PCs. So I thought that I have to share what I found. There is a Chipset circuit design issue identified in the Intel® 6 Series Chipsets. It is better to understand what is going on before you buys a new one.

So before you buy a Laptop or PC please read this.

Or before you buy your laptop or PC run CPU-Z on the machine and check the version of the south bridge. If it is B2 you are in trouble.

How to do a good presentation.

In this article I will highlight one major aspect you have to understand before you do a presentation. That is identifying the audience. There are four major types of people in a audience.

1. Amiable : 
   Devoted, consistent, dependable, and loyal, the Amiable is a hard worker and will persevere long after others have given up.
2. Driver :
   The Driver is a high achiever – a mover and shaker who is definitely not averse to risk.
   
3. Expressive :
   The Expressive, a verbally adept personality, is engaging, accommodating,supportive of others, persuasive, socially adept, and relationship- rather than task-oriented.
4. Analytic :
   The Analytical is polite but reserved, logical, fact- and task-oriented.
   

You have to identify following qualities of them to do a good presentation. Because they will search those qualities in you and your presentation . If you doesn't show the qualities they like,  nothing will happen.....

• patient
• loyal
• sympathetic
• team person
• relaxed
• mature
• supportive

• congenial

Expressive

Did Your Cling or Table Fan rotates slowly than before? Here is the solution. ඔබගේ වීදුලි පංකාව කැරකෙන්නේ පෙරට වඩා සෙමින්ද?

This is the circuit diagram of a simple fan. The fan symbol indicates the Armature Coil Windings. Rheostat indicates the speed controlling buttons.

There are two major reasons for slowness of the fan.

1. Capacitor is burned.
2. There is a short circuit in the winding or Some part of the winding burned.

To find out the reason, You have to do a small trick, Find the consensor of your fan, Cu the connecting wires to that condenser. then switch on the the fan and rotate fan blades with your hands. If fan starts to run in the early speed the fault occurred due to bad condenser. So you have to replace a one.


If the speed is same as before(Slow) most probably there can be a leek in the windings. So you have to replace total armature part of the fan. If it occurs in a cycling fan you have to forget of the fan. If you try to repair the winding of the fan it takes money than a new man. So replacing armature is better. You can buy it near 800 rupees. Hear is a picture of the motor.

The most Interesting Question in IEEE 4.0

This is a encrypted message passing technique. If you are interested read this question.

Digraph Cipher

Exchanging information securely has been a challenge and a fascination since the time human beings started communicating. A digraph cipher is an encryption mechanism that replaces each pair of letters in the plaintext (message to be encrypted) by another pair of letters. In order to encrypt and transmit a message, the sender and receiver must agree on a keyword. Before encryption, the letters of the alphabet are written in a 5x5 square (The Keyword is XTREM for all Encryptions), beginning with the keyword, and combining the elements I and J into a single cell. Next, the message is broken into pairs of letters called digraphs. So that each pair contains two unique letters, an x is added between any repeated letters that fall in the same pair or at the end to make a single final letter a digraph. All digraphs fall into one of three categories: both letters are in the same row; both letters are in the same column; or both letters are in different rows and columns. For encryption, letters in the same row are replaced by the letter to the immediate right of each one in the matrix. If a letter is at the end of a row, it is replaced by the letter at the beginning. Letters in the same column are replaced by the letter immediately below each one. If a letter is at the bottom of a row, it is replaced by the letter at the top. If the letters are in neither the same row nor the same column, the first letter is replaced by the letter in its row that is at the intersection with the column of the second letter. The second letter is replaced by the letter in its row that is at the intersection with the column of the first letter. The message is easily deciphered by the recipient using the same keyword.

Task

Please, write a program that takes a keyword and a message and returns the message in its encrypted format.

Encryption Square:

X T R E M

A B C D F

G H I/J K L

N O P Q S

U V W Y Z

Input

The program gets two unique inputs: the keyword and the message.

Valid assumptions:

1. Keyword contains only alphabets and message text contain only alphabets and spaces.

2. The message is only one line of text.

3. DO NOT include white spaces when comparing

4. Add X’s for double letters before adding X’s at the end to create an incomplete digraph

e.g. littles -> li tx tl e -> li tx tl ex

5. If I/J is selected as a digraph solution for a message, then the output should only be “I” (not IJ, J, I/J)

e.g. lp -> is

Output

The program outputs the given message in an encrypted form.

Sample InputKeyword: Xtreme
Message: This is fun

Sample Output

Message: Bolp lp azua

Java භාවිතයට අත්‍යවශ්‍යයි....Using JDK Tool Kit.......

Java යනු මෑත කාලයේ ඉතාම ජනප්‍රිය Programming Language ය. නමුත් එය භාවිතා කිරීමට නම් ඔබගේ පරිගණකයේ JDK toolkit ස්ථාපනය කල යුතුය. ඉන් පසු settings පහත පරිදි සකස් කල යුතුය.

To use the java and javac command in command prompt you have to edit these settings.
Right Click On My Computer-> Advanced System Settings->Environment Variables .

There Go to System Variables.



Check There is variable named as path.
Then click on that and click the edit button.
Then check these address contains to your java installation Folder.
If isn't go to java installation folder and go to jdktoolkit folder(Ex jdk1.6.0_01) and go to bin folder.
Then Copy the address of your folder from address bar.
Then Paste that address at last of the path vribale and put ; at last.
Then click Save.

Then check there is a variable named classpath.
if there is no such a variable, click on new.
Then enter classpath as name;
Enter .; as the value of that variable.
That will make java and java c commands enabled.
