I got my new graphics cards today! Here's a series of pictures:
The box:
My computer:
Hmm... Whats inside the box?
Look at those boxes! That's some nice boxes, I tell you.
Inside the boxes, we got a couple of more boxes.
And inside those boxes we got various items:
A nice doorhanger:
Various dongles and cables, including a crossfire bridge.
A card:
Two cards:
One card inserted in my computer:
Both cards inserted:
A couple of crossfire bridges:
Finally, I attached the crossfire brigdes:
Installing drivers:
My desktop :p
Thank you for reading.

The old PC
Sunday, 23 August 2009

I was on a flea market a couple of days ago, and guess what I found? An old computer from 1992!
It had no charger, so I plugged in my 1.5 A, 12 V power supply charger and... Nothing. After a while, I came to think that the amp delivered was just not enough. I brought up my car battery-charger, and guess what! It booted!
Since I couldn't use the car battery-charger forever, I constructed a charger from a 16v DC adapter.
But after testing the memory, the computer returned this error:
"CMOS RAM ERROR, CHECK BATTERY/RUN SETUP", so run the setup I did.
The BIOS got loaded!
My joy was, however, short. As I was to soon find out, the PC was stripped for it's harddisk before it was delivered to the flea market. But to my astonishment, I found out that my other lappy, from '99, actually had a harddisk that fitted in the old computer. I removed it from the newer computer, and installed it on the laptop.
Of course, the PC wouldn't boot since the file system on the newer harddisk was totally different from the old FAT16 this PC could read:
I made a floppy disk with MS-DOS, and pressed "any" key.
Yay! "STARTING MS-DOS"! It worked!
I now had to format the harddisk with FAT16. After that was done I had to install Microsoft Windows 3.11. That was easier said than done. The installation files were a total of 13MB, so i had to use 12 floppies!
I did get 3.11 installed correctly, and not long after, I saw the recognisable loading screen:
I had accomplished! The PC now contained Windows 3.11!
I loaded a diskette containing the best DOS game ever:
Copied the files and started it up:
To my astonishment, it worked flawlessly!
This has been a very fun project. Thank you for reading through!

Thoughts
In two days, the school starts in Norway. I do actually look forward to it. I've gotten quite lazy this holiday. But this will also mean that I will probably not be as active on the forums the following weeks. I hope I can get myself to concentrate in the math/english classes. Even though everything we 'learn' is too easy. I do look forward to seeing my friends again, too. Even though they are not the same 'type' as me, we do have very much fun together. This brings me on, there is actually only two guys in my entire school that I know have been programming. Both of them are my friends... Anyhow, wish me luck :)

C# Expression Calculator

C#
I have usually written all my programs in C++. Now, however, I decided to try out C#. I've heard a lot of great stuff about it. The first thing I tried out, was a windows forms expression calculator. The calculator first uses the Shunting-Yard algorithm to parse the inputted expression into Reverse Polish Notation, then use several stack methods to to calculate the final result. A snippet of the source code:
Stack<string> output = new Stack<string>();
string refr = "";
double num1 = 0;
double num2 = 0;
public Form1()
{
InitializeComponent();
}
private void outpush(string val , bool more )
{
if(!more)
{
output.Push(val+" ");
}
else
{
output.Push(val);
}
}
private void button1_Click(object sender, EventArgs e)
{
Stack<char> oper = new Stack<char>();
char[] exp = richTextBox1.Text.Replace(" ","").ToCharArray();
refr = "";
for(int i = 0; i < exp.Count(); i++)
{
if(Char.IsNumber(exp[i]))
{
if(exp.Count()-1 > i && Char.IsNumber(exp[i+1]))
{
outpush(Convert.ToString(exp[i]), true);
}
else
{
outpush(Convert.ToString(exp[i]), false);
}
}
else switch(exp[i])
{
case '+':
if(oper.Count()>0)
{
if (oper.ToArray()[0] == '*' || oper.ToArray()[0] == '/' || oper.ToArray()[0] == '^')
{
outpush(Convert.ToString(oper.Pop()), false);
}
}
oper.Push(exp[i]);
break;
case '-':
if (oper.Count() > 0)
{
if (oper.ToArray()[0] == '*' || oper.ToArray()[0] == '/' || oper.ToArray()[0] == '^')
{
outpush(Convert.ToString(oper.Pop()), false);
}
}
oper.Push(exp[i]);
break;
case '-':
if (oper.Count() > 0)
{
if (oper.ToArray()[0] == '*' || oper.ToArray()[0] == '/' || oper.ToArray()[0] == '^')

}
}
if (oper.Count() == 0) { goto errorlp; }
oper.Pop();
break;
case '^':
oper.Push(exp[i]);
break;
default:
break;
}
}
int count = oper.Count();
for(int i = 0; i < count; i++)
{
outpush(Convert.ToString(oper.Pop()), false);
}
int counto = output.Count();
for(int i = 0; i < counto; i++)
{
refr = output.Pop() + refr;
}
string[] input = refr.Split(' ');
Stack<double> numbers = new Stack<double>();
for(int i = 0; i < input.Count(); i++)
{
if(input[i] != ""){
if(Char.IsNumber(input[i],0))
