XP is an agile software development methodology focused on frequent code integration, pair programming, testing, and refactoring. It emphasizes principles like pair programming, testing code early and often, integrating code changes multiple times daily through continuous integration, and refactoring code to improve design without changing functionality. However, XP may not scale well to large teams or virtual teams.

Think like a hacker for better security awarenessCOMSATS
The document discusses thinking like hackers to improve security awareness. It recommends arming employees with knowledge of common attack methods and vulnerable assets. Security awareness involves reminding people to practice safety daily, like wearing seatbelts, and focusing training on relevant best practices instead of overwhelming staff. Compliance is important for public safety, so consider penalties to increase adherence to training.

The document discusses the history and development of the internet over the past 50 years, from its origins as a US military program called ARPANET to the commercialization of the world wide web in the 1990s. It grew exponentially from the 1980s onward and became a major force in communications, business, and society through new technologies and greater public access to computers and online content. The internet has profoundly shaped modern life and continues to rapidly evolve and impact nearly all aspects of the global community.
The document discusses the benefits of exercise for mental health. It states that regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise has also been shown to enhance self-esteem and quality of life.
The document discusses the history and development of artificial intelligence over several decades. Early research focused on symbolic approaches using rules and logic but progress was slow. More recently, machine learning techniques such as deep learning have achieved significant successes in areas like computer vision and natural language processing by using neural networks trained on large datasets. However, fully general artificial intelligence remains an ongoing challenge.

How to print out a list of all files in a folderCOMSATS
Using the Command Prompt, you can print a list of files in a folder by navigating to the folder in CMD, using the "dir" command to output the file list to a text file, and then opening and printing the text file. For example, to get a list of all files in the E:\movies folder, you would use "dir > list.txt" in CMD after navigating to that folder, which would create a list.txt file containing the file list that could then be opened and printed.
This document provides examples of how to mount and unmount filesystems and partitions in Linux using the mount and umount commands. It discusses:
1. Mounting partitions and filesystems using mount, including CD-ROMs, viewing all mounts, mounting all filesystems listed in /etc/fstab, mounting a specific filesystem from /etc/fstab, viewing mounts of a specific type like ext2, mounting a floppy disk, bind mounting, accessing contents from a new mount point, mounting without writing to /etc/mtab, and mounting with read-only or read-write access.

1. How To Downgrade From Windows 7 To XP
(Step-by-Step)
With the Windows 7 Release Candidate expiration date is just a few days away, many
of Windows 7 RC users are asking a way to downgrade to Windows XP/Vista. In this
guide, we will show you how to downgrade from Windows 7 to XP.
And if you want to downgrade to Vista from Windows 7, please refer our how to
downgrade from Windows 7 to Vista article.
1. Open your Windows 7 drive (usually C drive) and make sure that you haven’t
deleted the Windows.old folder, which was created by Windows while installing
Windows 7 on XP drive. Note that without the help of Windows.old folder you won’t be
able to downgrade from Windows 7.
2. Now check the size of Windows.old folder by right-clicking and then selecting
properties. Make sure that Windows.old folder size is less than two times the amount of
free space available on Windows 7 drive (C drive). If the Windows.old folder size is two
times as large as the Windows 7 drive free space, disable system restore feature and
also disk cleanup to get some free space.
2. Please note down your Windows 7 drive letter and also DVD drive letter before
proceeding to the next step.
3. Insert your Windows 7 installation disc in the drive and reboot your machine. Press
any key when prompted to do so.
4. Select your language, time, keyboard type and then hit Next button to continue.
3. 5. In the Install Windows screen, click Repair your computer option to open System
Recovery Options.
6. Here select your Windows 7 OS and note down your Windows 7 Drive letter before
clicking Next.
7. In the following window, click Command Prompt to start downgrading from
Windows 7 to XP.
4. 8. First you need to move all the contents of your Windows 7 drive to a folder. So type
the following commands one by one and then hit enter after each command (here “D”
is your Windows 7 drive letter).
D:
Md Win7
Move Windows Win7Windows
Move "Program Files" "Win7Program Files"
Move Users Win7Users
Attrib –h –s –r ProgramData
Move ProgramData Win7ProgramData
Rd "Documents and Settings"
9. Next you need to copy all the contents of Windows.old folder to the drive. Again,
type all the commands mentioned below one by one and then hit enter after each
command.
move /y d:Windows.oldWindows d:
move /y "d:Windows.oldProgram Files" d:
move /y "d:Windows.oldDocuments and Settings" d:
5. 10. Next task is to restore the boot sector by entering the following command:
E:bootbootsect /nt52 d:
(Where E is your DVD driver letter & D is OS drive letter)
11. Finally restore the boot.ini file by executing the following commands:
Attrib –h –s –r boot.ini.saved
Copy boot.ini.saved boot.ini
12. Type Exit and reboot your machine to start using your Windows XP again. You are
done! If you want to free up some disk space, delete Win7 folder in the root of your XP
drive. Good luck!
