Hacker
A hacker is a person who breaks into computers and computer networks for profit, in protest, or because they are motivated by the challenge.[1] The subculture that has evolved around hackers is often referred to as the computer underground but it is now an open community.[2]
Other definitions of the word hacker exist that are not related to computer security. They are subject to the long standing hacker definition controversy about the true meaning of hacker. In this controversy, the term hacker is reclaimed by computer programmers who argue that someone breaking into computers is better called a cracker,[3] not making a difference between computer criminals ("black hats") and computer security experts ("white hats"). Some white hat hackers claim that they also deserve the title hacker, and that only black hats should be called crackers.

Internet Connection Sharing on Windows XP
Internet Connection Sharing on Windows XP
This trick shows you how to share your internet connections on multiple computers within a workgroup with Windows XP. Windows XP has a built-in feature that called "Internet Connection Sharing" (ICS) that allows home users to share their internet connections on multiple computers.If you are not familiar with the network configurations, the easiest way to share your internet connection is to purchase a router or hub. Use this trick only if you don't have a router, or don't want to use a router, or if you just want to try out the feature.
A simple way to understand this feature is, you are making your host computer (the computer directly connects to the internet) functioning as a router for other computers.
What do you need?
- A "Host" computer that running Windows XP. This computer must have at least TWO (2) network adapters. One adapter - let's call it "Adapter #1" - connects to the internet and another, "Adapter #2", connects to a hub or directly to other computers.
- Client computer(s), which run any version of Windows. A client computer can be connected to the host computer directly by a cross-over cable or indirectly through a hub.
- This trick assumes that the host computer is connected to the internet and you are able to access the internet on this computer.
Configure the Host Computer
- Logon the host computer as Administrator.
- Click Start >> Control Panel.
- Click Network and Internet Connections.
- Click Network Connections.
- Right-click the connection that you use to connect to the internet (the connection with Adapter #1). This connection can be either a high-speed internet connection or a dial-up connection.
- Click Properties.
- Click Advanced tab.
- Under Internet Connection Sharing, select the Allow other network users to connect through this computer's Internet connection check box.
- If you are sharing a dial-up Internet connection, select the Establish a dial-up connection whenever a computer on my network attempts to access the Internet check box if you want to permit your computer to automatically connect to the Internet.
- Click OK. You'll reieve the following message:
When Internet Connection Sharing is enabled, your LAN adapter will be set to use IP address 192.168.0.1. Your computer may lose connectivity with other computers on your network. If these other computers have static IP addresses, it is a good idea to set them to obtain their IP addresses automatically. Are you sure you want to enable Internet Connection Sharing? - Click Yes.
To use the shared connection from the Host computer, a client computer must be configured with "Automatic IP address". The main configurations are:
- Configure TCP/IP Automatic IP
- Configure Internet Connection
The following procedures are for Windows XP client computers.
- Log on to the client computer as Administrator or as Owner.
- Click Start >> Control Panel.
- Click Network and Internet Connections.
- Click Network Connections.
- Right-click Local Area Connection, and then click Properties.
- Click the General tab, click Internet Protocol (TCP/IP) in the This connection uses the following items list, and then click Properties.
- In the Internet Protocol (TCP/IP) Properties dialog box, click Obtain an IP address automatically (if it is not already selected), and then click OK.
- Click Start >> Control Panel
- Click Network and Internet Connections.
- Click Internet Options.
- In the Internet Properties dialog box, click the Connections tab.
- Click the Setup button. The New Connection Wizard starts.
- On the Welcome to the New Connection Wizard page, click Next.
- Click Connect to the Internet, and then click Next.
- Click Set up my connection manually, and then click Next.
- Click Connect using a broadband connection that is always on, and then click Next.
- On the Completing the New Connection Wizard page, click Finish.
- Exit Control Panel and test the internet. You might need to restart the computer.
Create Ghost Bootable SD Card or USB Flash Drive
Create Ghost Bootable SD Card or USB Flash Drive
It's a good practice to create an image of your hard drive before you start using it. Especially when you had to build that computer from scratch and spent hours installing the operating system and all of your favorite apps...
As Symantec Ghost becomes more user friendly, people start to recognize this idea. The idea also works well when you need to clean your PC from viruses. In case anything goes wrong with the operating system, you just need to restore the image using the Symantec bootable CD.
However, the problem comes when we deal with the new version of those small laptops: The netbooks! which usually don't come with a built-in CD-ROM drive to bootup the PC.
The most simple solution would be buying an external CD-ROM drive, which costs you money. And in some cases, you just want to bootup the Symantec Ghost.... with whatever available!

The good news: Almost every recent laptop/netbook comes with a card reader, and even if you wasn't lucky enough, your laptop/netbook should have a USB port!
This guide will tell you how to create a bootable SD card or a USB flash drive with Symantec Norton Ghost.
This task can be done with several different versions of Symantec Ghost; however, the steps from this articles are based on Symantec Ghost 14.

What you need?
· Symantec Ghost 14 bootable CD. (Some other versions might also work)
· A PC with bootable CD/DVD drive.
· An SD card (either SD or SDHC), or a USB thumb drive. The size can be as minimum as 1 GB. You can also pick a large SD card if you want to store your hard drive image to the card as well.
· An SD slot or a card reader (for SD card) or a USB slot (for thumb drive)
Follow the steps in order. Use this guide at your own risks.
1. First, check to make sure your CD/DVD drive is bootable. (See your BIOS manual or PC user guide for details since this is out of the scope of this article).
2. - For SD card: Make sure the SD slot or the card reader is available. if it's a card reader, connect it to the PC. Also insert the card.
- For USB thumb drive: Make sure the drive is inserted into one of the USB slots.
- For USB thumb drive: Make sure the drive is inserted into one of the USB slots.
3. Bootup the computer using the Symantec Ghost CD (Details vary on different computers). On Windows XP, during the startup, you should see the prompt "Press any key to boot from CD...".
4. Once the Symantec Recovery startup is complete, you should see the main screen of Symantec Ghost 14 Recovery similar to this image:
5. Select "Analyze" from the left menu.
6.
7. Then click on "Open Command Shell Window". A command prompt window will display.
8. At this command prompt window, type: "diskpart" (one word, without quotes) and hit enter. The prompt now changed to "DISKPART>"
9. Now type "list disk" and hit enter. You should now see a list of all available disks. Base on the size of each disk listed, find the one that matching your SD card (or thumb drive) and note its disk number under "Disk ###". If you don't see your SD card (or flash drive) listed, verify if it is inserted or plugged in (you might need to restart the computer and try again).
10. Type "select disk <n>" (replace <n> with the disk # noted from the previous step) then hit enter.
Important!! Besure to select the correct disk (your SD card or thumb drive) as you will be erasing the drive.
Sample image with a 4-GB SD selected:
Important!! Besure to select the correct disk (your SD card or thumb drive) as you will be erasing the drive.
Sample image with a 4-GB SD selected:
11. Create a primary partition for the the disk by executing the following sequence of commands:

How to change the time allowed to wait for an application at shutdown?
". How to change the time allowed to wait for an application at shutdown?"
When you shutdown a Windows (XP, 2000, or 2003) computer, the OS will tell each of the running applications and services to close, and gives them a period of time (20 seconds) to do so gracefully. If the application doesn't respond, the user is prompted with options to cancel, wait, or kill the application. With a change to the following Registry entry, you can adjust the 20 second timeout period, which can be helpful if you have an application that normally takes longer to respond when shutting down. Keep in mind that the longer you make the timeout period, the longer it could potentially take your computer to shut down. In the case of a UPS shutdown because of loss of power, this could potentially extend the shutdown time past the life of the battery, so use discretion when changing this entry.
