Indonesian Bank Redrawing 4 Money

Indonesian bank will redraw 4 kinds of paper money which were drew on 1998-1999.

Those money are Rp. 10000 which has National Hero, Cut Nyak Dhien picture, Rp. 20000 which has National Hero, Ki Hajar Dewantara picture, Rp. 50000 which has National Hero, WR Supratman picture and Rp. 100000 which has Proclamator of Indonesia, Soekarno and Hatta.

The redrawing counted from 31th of December 2008, if you still have those money, better to change it at public bank. The changing service is up to December 20013 or 5 years after the redrawing.

And you still can change your money at Indonesian Bank untill December 2018 or 10 years after the redrawing. But, better to change those money as fastest you can because there are no benefit for saving money which can be used for buy somethig. Except you're money collector.

40 Years, The History of Mouse

On December 9, 1968, a group of engineers led by Douglas Engelbart crowded into an auditorium in San Francisco to show off a groundbreaking new system they'd designed for interacting with a computer. Moving beyond the cold realities of the keyboard (and even the punch card), Engelbart's creation would open up a new world of computing from that day on. His invention: The mouse.

40 years ago tomorrow, Engelbart demonstrated the mouse along with numerous other innovations in front of 1,000 computer professionals, marking its official public unveiling. The research took six years and the work of some 20 engineers just to get to that point.

The first mouse was quite primitive by today's standards. It didn't even have a ball inside (much less an optical sensor), but rather two large discs set perpendicular to each other inside: Movement of one wheel handled location along the x axis and the other dealt with the y axis. The original mouse was quite large, barely fitting in the user's hand, but Engelbart envisioned that you would keep one hand on the mouse at all times and the other on a special one-handed keyboard instead of a standard QWERTY-styled model.

It would take years for the mouse to catch on (beginning primarily with the introduction of the original Macintosh in 1984): By that point Englebart's patent had expired and he never received any royalties for inventing the thing. Try to imagine how much money he'd have if he had earned a penny from every mouse ever produced...

In lieu of compensation, our gratitude and salutations will have to suffice. If you want to take a real stroll down high-tech's memory lane, check out the complete 100-minute demo from 1968 -- along with Engelbert's other pioneering innovations like hypertext and screen-sharing technology -- at Stanford's video archive site.

E-commerce revenues fall for first time ever

The situation for online shopping is even worse than previously predicted. While earlier estimates had predicted that the growth of e-commerce revenues would dramatically slow, new data shows that online sales are actually falling vs. last year. It's a watershed bit of news because it's the first time that's ever happened.

According to ComScore, sales for the first 23 days of November fell 4 percent vs. the same period in 2007. The total haul: $8.19 billion spent online during that period. Sounds like a lot, but it's got e-tailers scared out of their minds.

There may be a light at the end of the tunnel, at least. Though the current figures are dire, the company says it predicts some recovery over the rest of the year thanks to price wars and the current "cocooning" trend of staying home instead of venturing out to shop. ComScore is figuring overall sales for next month will end up right where they were in 2007, and since 2007 was huge for online sales, that's significant.

"All bets are off," however, if "any more significant bad news" erupts over the next few weeks. "We have our fingers crossed that the stock market will not go through another 2,000-point meltdown," says ComScore chairman Gian Fulgoni. Yikes, man! Don't even joke about something like that!

Concepts of Pointer in C

I'll try to explain about pointer '*' in C Programming Language

Basicly, pointer '*' is a variable which refers to other variable. How can be? Pointer isn't contains a value of variable but contains memory address of the refers variable.

Let's take an example

- 'Home' variable contains 'krisna'
- Address of 'Home' variable is in '1st street'

- 'Mail' pointer variable contains '1st street' which is address of home variable
- 'Mail' pointer variable itself has an address let's say in '5th street'

- If we ask where is the 'Mail'? the answer is '5th street'
- What is the 'Mail' contains? the answer is 'Home' address (1st street)
- What is the 'Mail' refers? the answer is 'krisna'

Still confusing about pointer? let's take a look for programming code

#include "stdio.h"
#include "stdlib.h"

int main(int argv, char** args){

 system("cls");

 int   var1  = 10;
 int*  var2  = &var1;
 int** var3  = &var2;
 int   var[5]={0,1,2,3,4};

 printf("var1\t%d",var1);
 printf("&var1\t%d",&var1);

 printf("*var2\t%d",*var2);
 printf("var2\t%d",var2);
 printf("&var2\t%d",&var2);

 printf("**var3\t%d",**var3);
 printf("*var3\t%d",*var3);
 printf("var3\t%d",var3);
 printf("&var3\t%d",&var3);

 printf("&var[0]\t%d",&var[0]);
 printf("var[0]\t%d",var[0]);
 printf("var\t%d",var);

 return 0;
}

Now, the explaination...

• var1 is an integer variable which contains value of 10

• var2 is a pointer to integer variable which contains address of var1
• *var2 refers to value of var1

• var3 is pointer to pointer to integer which contains address of var2
• *var3 refers to value of var2 (address var1)
• so, *var3 can be equal with var2
• then, **var3 refers to value which var2 refers (value of var1)

• var is an array of integer which has 5 elements
  
• the value of var is equals with address var[0]
• so, we can say that var is a pointer to var[0]
