Chip breaks speed record in deep freeze

What is your PC clock speed?

(800 MHz, 1 GHz, 1.8 GHz , 2.4 GHz, 2.6 GHz, 3 GHz Dualcore, 3.6 GHz)?

If your find the answer in the above line then, it shows you have a Grand old PC

Research has gone to such an extent, and created a chip with clock speed of 350 GHz at room temperature.
It is also possible to have a chip with a clock speed of 1THz (@ - 459 F or 0 K or -273 C ) when liquid helium is used for cooling.
It is made up of (SiGe). Silicon and Germanium, it is manufactured by IBM and Georgia Tech.

Tracking file download

We usually put a hyperlink to download a file. But the following code helps to track the download. We can check whether the user has successfully downloaded the file or not. This can be used in juke box or movie download sites to prevent multiple downloads.

private void DownloadFile(string strfile)
{
System.IO.Stream iStream = null;
byte[] buffer = new Byte[1000];
int length;
long dataToRead=-1;

bool startstatus=false;
string filepath = strfile;
string filename = System.IO.Path.GetFileName(filepath);

try
{
iStream = new System.IO.FileStream(filepath, System.IO.FileMode.Open,System.IO.FileAccess.Read, System.IO.FileShare.Read);
dataToRead = iStream.Length;

Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", "attachment; filename=" + filename);

while (dataToRead > 0)
{
// Verify that the client is connected.
if (Response.IsClientConnected)
{
// Read the data in buffer.
length = iStream.Read(buffer, 0, 1000);
// Write the data to the current output
Response.OutputStream.Write(buffer, 0, length);

// Flush the data to the HTML output.
Response.Flush();
buffer= new Byte[1000];
dataToRead = dataToRead - length;

if(startstatus == false)
{
// Started downloading
startstatus=true;
}
}
else
{
//prevent infinite loop if user disconnects
dataToRead = -1;
// disconnected or unable to download
}
}
}
catch (Exception ex)
{
dataToRead = -1;
}
finally
{
try
{
if(dataToRead == -1)
{
// disconnected or unable to download
}
else
{
// file successfully downloaded
}
if (iStream != null)
{
//Close the file.
iStream.Close();
}
}
catch(Exception ex)
{

}
}
}
