Core i7, New Generation Of Intel CPU

2008-08-09T23:52:00.000-07:00

The latest reports on Intel's upcoming Nehalem micro-architecture unveiled the fact that the company chose to release the CPUs under the brand name Core i7. The giant chip maker didn't drop the "Core" from the denomination of the processors, as the news site Expreview states, which may suggest the fact that they are meant to let end-users know that the Core 2 micro-architecture is being leveraged to a new level.

This ad zapped.
Today's Intel desktop, mobile and server microprocessors use the Core 2 architecture, but the name of Core i7 does not show the actual improvements the next-to-come CPUs will bring. Among the micro-architectural enhancements included in the Nehalem processors is the increased parallelism, translated into the execution of 33 percent more concurrent micro-operations at the same time than the predecessors. Faster unaligned cache accesses and quicker synchronization primitives come with the new architecture as well. Intel also included a second level branch predictor that is meant to exclude situations when execution units are idling.

The Nehalem processors have been designed with a brand new cache sub-system. A second level 512 entry translation look-aside buffer will come with the new CPUs, added to the first level TLB, which is intended to reduce the so-called TLB miss rate, this being the first time this feature is included on the x86 microprocessors. Certain implementations of the Nehalem chips will also come with a three-level cache hierarchy: 64KB L1 (32KB for data, 32KB for instructions), 256KB L2 cache per core, 8MB L3 cache per processor. The traditionally used cache policy on Intel processors is inclusive.

The chip manufacturer also said that the high-end Nehalem microprocessors would come with 2 to 8 cores, triple-channel DDR3 memory controllers (initially, they will support up to 1333MHz clock-speed), would use Quick Path Interconnect (QPI) bus, and would support multi-threading technology similar with Intel Hyper-Threading.

The first Nehalem processor that will come to the market is the code-named Bloomfield. This is a quad-core chip manufactured under the 45nm fabrication process, supporting 731 million transistors. The PC market will see 3 Bloomfield processors launched this year, but the only Core i7 Extreme Edition processor currently revealed is the $999 top-of-the-line Bloomfield. Intel is said to officially announce all the i7 processors and i7 Extreme Edition processor on August 11, while the chips will become available starting with the fourth quarter of 2008.

(JAVA GUI)

2008-08-01T06:01:00.000-07:00

JFrame have possibility too make a splash screen, but, better we use JWindow. This component desained to make window without title bar, as same as splash screen.
To make a splash screen, there are three step. First, dislay something into splash screen, it can be text or picture. Second, we set position of splash screen exact in the middle of the screen. Last step, we set how long splash screen is displayed


//SPLASH SCREEN

package musicplayerv2;

import java.awt.Dimension;
import java.awt.Toolkit;
import javax.swing.JWindow;
import javax.swing.JLabel;
import javax.swing.ImageIcon;

public class Splash extends JWindow 
{
    public Splash(int timeOut) 
    {
        add(new JLabel(new ImageIcon("images/mypicture.jpg")));  // image you want to show
        
        pack();
        
        Dimension dim=Toolkit.getDefaultToolkit().getScreenSize();  // gaining screen size
        
        int x=(dim.width-getSize().width)/2;  // set image position in the middle
        int y=(dim.height-getSize().height)/2;
        
        setLocation(x, y);
        setVisible(true);  // show window
        
        try 
        {
            Thread.sleep(timeOut);  // waiting...
        } 
        catch (InterruptedException ex) 
        {
            System.err.println(ex.getMessage());
        }
        dispose();  // close and cleaning window resource
    }

(C#) Tower Of Hanoi

2008-07-31T05:13:00.001-07:00

Hello again, now, for killing time in holiday,i wrote a program again :) , the program is Tower Of Hanoi. Here sort explanation of Tower Of Hanoi, i took it from Wikipedia:
The Tower of Hanoi or Towers of Hanoi (also known as The Towers of Benares) is a mathematical game or puzzle. It consists of three rods, and a number of disks of different sizes which can slide onto any rod. The puzzle starts with the disks neatly stacked in order of size on one rod, the smallest at the top, thus making a conical shape.
The objective of the puzzle is to move the entire stack to another rod, obeying the following rules:

Only one disk may be moved at a time.

Each move consists of taking the upper disk from one of the pegs and sliding it onto another rod, on top of the other disks that may already be present on that rod.

No disk may be placed on top of a smaller disk.

Using recurrence relation, the exact number of moves that this solution requires can be calculated by: $2 h - 1$

here the code written in C#:


using System;
using System.Collections.Generic;
using System.Text;

namespace Hanoi
{
    class Program
    {
        static void Main(string[] args)
        {
            int x;
            char from='A', to='B', help='C';

            do{
                try
                {
                    Console.Write("  input number of disk: ");
                    x = Int32.Parse(Console.ReadLine());
                }
                catch (FormatException e)
                {
                    x = -10;
                }
            }while(x==-10 || x>10);
            Console.WriteLine("\n  from = A, to = B, help = C\n");
            hanoi(x, from, to, help);

            Console.Read();
        }

        static void hanoi(int x, char from, char to, char help)
        {
            if (x > 0)
            {
                hanoi(x - 1, from, help, to);
                move(x, from, to);
                hanoi(x - 1, help, to, from);
            }

        }

        static void move(int x, char from, char to)
        {
            Console.WriteLine("  move disk "+x+" from "+from+" to "+to);
        }

    }
}

Linux Keyboard Shortcut

2008-07-31T05:11:00.001-07:00

Virtual terminals

Ctrl + Alt + F1
Switch to the first virtual terminal. In Linux, you can have several virtual terminals at the same time. The default is 6.

Ctrl + Alt + Fn
Switch to the nth virtual terminal. Because the number of virtual terminals is 6 by default, n = 1...6.

tty
Typing the tty command tells you what virtual terminal you're currently working in.

Ctrl + Alt + F7
Switch to the GUI. If you have X Window System running, it runs in the seventh virtual terminal by default. If X isn't running, this terminal is empty.

X Window System

Ctrl + Alt + +
Switch to the next resolution in the X Window System. This works if you've configured more than one resolution for your X server. Note that you must use the + in your numpad.

Ctrl + Alt + -
Switch to the previous X resolution. Use the - in your numpad.

MiddleMouseButton
Paste the highlighted text. You can highlight the text with your left mouse button (or with some other highlighting method, depending on the application you're using), and then press the middle mouse button to paste. This is the traditional way of copying and pasting in the X Window System, but it may not work in some X applications.

If you have a two-button mouse, pressing both of the buttons at the same time has the same effect as pressing the middle one. If it doesn't, you must enable 3-mouse-button emulation.

This works also in text terminals if you enable the gpm service.

Ctrl + Alt + Backspace
Kill the X server. Use this if X crashes and you can't exit it normally. If you've configured your X Window System to start automatically at bootup, this restarts the server and throws you back to the graphical login screen.

Command line - input

Home or Ctrl + a
Move the cursor to the beginning of the current line.

End or Ctrl + e
Move the cursor to the end of the current line.

Alt + b
Move the cursor to the beginning of the current or previous word. Note that while this works in virtual terminals, it may not work in all graphical terminal emulators, because many graphical applications already use this as a menu shortcut by default.

Alt + f
Move the cursor to the end of the next word. Again, like with all shortcuts that use Alt as the modifier, this may not work in all graphical terminal emulators.

Tab
Autocomplete commands and file names. Type the first letter(s) of a command, directory or file name, press Tab and the rest is completed automatically! If there are more commands starting with the same letters, the shell completes as much as it can and beeps. If you then press Tab again, it shows you all the alternatives.

This shortcut is really helpful and saves a lot of typing! It even works at the lilo prompt and in some X applications.

Ctrl + u
Erase the current line.

Ctrl + k
Delete the line from the position of the cursor to the end of the line.

Ctrl + w
Delete the word before the cursor.

Command line - output

Shift + PageUp
Scroll terminal output up.

Shift + PageDown
Scroll terminal output down.

clear
The clear command clears all previously executed commands and their output from the current terminal.

Ctrl + l
Does exactly the same as typing the clear command.

reset
If you mess up your terminal, use the reset command. For example, if you try to cat a binary file, the terminal starts showing weird characters. Note that you may not be able to see the command when you're typing it.

Command line - history

history
When you type the history command, you'll see a list of the commands you executed previously.

ArrowUp or Ctrl + p
Scroll up in the history and edit the previously executed commands. To execute them, press Enter like you normally do.

ArrowDown or Ctrl + n
Scroll down in the history and edit the next commands.

Ctrl + r
Find the last command that contained the letters you're typing. For example, if you want to find out the last action you did to a file called "file42.txt", you'll press Ctrl + r and start typing the file name. Or, if you want to find out the last parameters you gave to the "cp" command, you'll press Ctrl + r and type in "cp".

Command line - misc

Ctrl + c
Kill the current process.

Ctrl + z
Send the current process to background. This is useful if you have a program running, and you need the terminal for awhile but don't want to exit the program completely. Then just send it to background with Ctrl+z, do whatever you want, and type the command fg to get the process back.

Ctrl + d
Log out from the current terminal. If you use this in a terminal emulator under X, this usually shuts down the terminal emulator after logging you out.

Ctrl + Alt + Del
Reboot the system. You can change this behavior by editing /etc/inittab if you want the system to shut down instead of rebooting.
