Fix the problem with "Active Desktop Recovery"

Having problem with your "Active Desktop Recovery"?
No need to worry at all, just a simple way to solve your problem without formating your operating system over and over again.

There are 2 Methods to solve your problem:

Method 1:

* Run "regedit"

* Find this entry:
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Desktop\SafeMode\Components

* Change the key value - DeskHtmlVersion REG_DWORD 0x00000110(272) to decimal zero

* Close "regedit". Log off and log in again.


Method 2:

Copy the code given below to notepad and save as activedesktop.vbs (vbs is the extension), run the file. Then logoff from your account and log in again.

HKEY_CURRENT_USER = &H80000001
strComputer = "."
Set objReg = GetObject("winmgmts:\\" & strComputer & "\root\default:StdRegProv")
strKeyPath = "Software\Microsoft\Internet Explorer\Desktop\SafeMode\Components"
strValue = "0"
ValueName = "DeskHtmlVersion"
objReg.SetDWORDValue HKEY_CURRENT_USER, strKeyPath, ValueName, strValue

Walla! it worked and my problem is solved!

*** Method 1 is not recommended for beginners.
And after all, DO IT AT YOUR OWN RISK.

Good Luck.

Command Prompt on Right-Click

Many computer users, specially the programmers, need to launch a command prompt window every once in a while to execute some dos/shell commands. The problem is, when a command prompt window launched, the default path is normally the system path or the user profile's path. The users will then have to do all the "cd" commands to change the directories to the path he/she wants.

This trick shows you how to add an option called "Command Prompt" when you right-click on a folder in Windows. With this option, a Command Prompt Window will launch and its current directory will be the path to the folder you've selected

There are 2 solutions:
1. Edit the registry editor
2. Download the registry file and apply it on your computer

Solution 1: Manually edit the registry

1. Start > Run

2. Enter "regedit" and hit Enter

3. Expand to "HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell"

4. Right-click on "shell" and select New > Key

5. Make sure a new key is created under "shell". Change the name of this key to "Command Prompt"

6. Right-click on this new key "Command Prompt" and select New > Key

7. Change the name of this key to "command"

8. Double-click on the "(Default)" text on the right window to bring up the edit box

9. Enter this text into the Value Data field:cmd.exe "%1"

10.Click OK and close the registry.


Solution 2: Download the registry file and apply it on your computer.

1. Download this registry file Here

2. Unzip it to a temp folder, then double-click on the .reg file to add the registry data

Hide all drives from My Computer

How to Hide all the drives(C:, D:, E:,...etc) in "My Computer"

This is a great trick you can play on your friends. To disable the display of local or networked drives when you click My Computer.

1. Go to Start -> Run.

2. Type regedit

3. Now go to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

4. In the right pane, create a new DWORD item and name it NoDrives (it is case sensitive).

5. Modify it's value and set it to 3FFFFFF (Hexadecimal) .

6. Restart your computer.

7. So, now when you click on My Computer, no drives will be shown.

To enable display of drives in My Computer, simply delete the DWORD item that you have created. Restart your computer. The drives will be visible again.

Do it at your own risk

Output Text from Dos Prompt to File

This is a small trick that many Dos users might already know. The trick just shows you how to run a Dos command and instead of displaying the outputs on the screen, it saves the outputs into a file.

This trick is very helpful when you want to save the result of a dos command to a file to email it or read/print it later. For example, you can print out your network configuration data and email it to a technical support.

Here's how

simply put a ">" and the destination file at the end of the dos command. Examples:

This command outputs the IP configurations to the file "ipdata.txt" in "C" drive:
ipconfig /all > C:\ipdata.txt

This command outputs the "Path" configurations to the file "pathdata.txt" in the floppy drive "A":
path > A:\pathdata.txt

This command outputs help text of the command "copy" to the file "copyhelp.txt" in "C" drive:
copy /? > C:\copyhelp.txt

Show/Hide Hidden Files and Folders using Registry

The instructions below would help you to:

  • Show (or hide) hidden files and folders using the Registry Editor.

Showing all files and folders is good in certain ways. Windows, by default, disables this option to keep the users from accidently deleting files. It is a good practice to hide those files and folders if you don't want to mess with them. They have been created that way for some good reasons. However, to many of us, specially the software programmers, it might be more convenient to work with files/folders when we have them all displayed.

IMPORTANT This article contains information about registry modification. Modifying the registry incorrectly might cause critical problems to your computer. Make sure you understand the registry and back it up before modifying it.

Use this tricks at your own risk

Here's how to enable/disable hidden files/folders using the "Registry Editor"

1. Open the "Registry Editor" ("Start" >> "Run", then type "regedit" and Enter).

2. Expand to the following key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced

3. If the value "Hidden" exists, double-click on it to edit its value to (1 = show hidden, 2 = do not show)

4. If the value "Hidden" does not exist, create it as followsName: HiddenType: DWORDValue: 1(1: show hidden, 2: do not show)

What is 3G?

3G refers to the third generation of mobile telephony (that is, cellular) technology. The third generation, as the name suggests, follows two earlier generations.

The first generation (1G) began in the early 80's with commercial deployment of Advanced Mobile Phone Service (AMPS) cellular networks. Early AMPS networks used Frequency Division Multiplexing Access (FDMA) to carry analog voice over channels in the 800 MHz frequency band.

The second generation (2G) emerged in the 90's when mobile operators deployed two competing digital voice standards. In North America, some operators adopted IS-95, which used Code Division Multiple Access (CDMA) to multiplex up to 64 calls per channel in the 800 MHz band. Across the world, many operators adopted the Global System for Mobile communication (GSM) standard, which used Time Division Multiple Access (TDMA) to multiplex up to 8 calls per channel in the 900 and 1800 MHz bands.

The International Telecommunications Union (ITU) defined the third generation (3G) of mobile telephony standards – IMT-2000 – to facilitate growth, increase bandwidth, and support more diverse applications. For example, GSM could deliver not only voice, but also circuit-switched data at speeds up to 14.4 Kbps. But to support mobile multimedia applications, 3G had to deliver packet-switched data with better spectral efficiency, at far greater speeds.

However, to get from 2G to 3G, mobile operators had make "evolutionary" upgrades to existing networks while simultaneously planning their "revolutionary" new mobile broadband networks. This lead to the establishment of two distinct 3G families: 3GPP and 3GPP2.

The 3rd Generation Partnership Project (3GPP) was formed in 1998 to foster deployment of 3G networks that descended from GSM. 3GPP technologies evolved as follows.

• General Packet Radio Service (GPRS) offered speeds up to 114 Kbps.

• Enhanced Data Rates for Global Evolution (EDGE) reached up to 384 Kbps.

• UMTS Wideband CDMA (WCDMA) offered downlink speeds up to 1.92 Mbps.

• High Speed Downlink Packet Access (HSDPA) boosted the downlink to 14Mbps.

• LTE Evolved UMTS Terrestrial Radio Access (E-UTRA) is aiming for 100 Mbps.

GPRS deployments began in 2000, followed by EDGE in 2003. While these technologies are defined by IMT-2000, they are sometimes called "2.5G" because they did not offer multi-megabit data rates. EDGE has now been superceded by HSDPA (and its uplink partner HSUPA). According to the 3GPP, there were 166 HSDPA networks in 75 countries at the end of 2007. The next step for GSM operators: LTE E-UTRA, based on specifications completed in late 2008.

A second organization – the 3rd Generation Partnership Project 2 (3GPP2) -- was formed to help North American and Asian operators using CDMA2000 transition to 3G. 3GPP2 technologies evolved as follows.

• One Times Radio Transmission Technology (1xRTT) offered speeds up to 144 Kbps.

• Evolution – Data Optimized (EV-DO) increased downlink speeds up to 2.4 Mbps.

• EV-DO Rev. A boosted downlink peak speed to 3.1 Mbps and reduced latency.

• EV-DO Rev. B can use 2 to 15 channels, with each downlink peaking at 4.9 Mbps.

• Ultra Mobile Broadband (UMB) was slated to reach 288 Mbps on the downlink.

1xRTT became available in 2002, followed by commercial EV-DO Rev. 0 in 2004. Here again, 1xRTT is referred to as "2.5G" because it served as a transitional step to EV-DO. EV-DO standards were extended twice – Revision A services emerged in 2006 and are now being succeeded by products that use Revision B to increase data rates by transmitting over multiple channels. The 3GPP2's next-generation technology, UMB, may not catch on, as many CDMA operators are now planning to evolve to LTE instead.

In fact, LTE and UMB are often called 4G (fourth generation) technologies because they increase downlink speeds an order of magnitude. This label is a bit premature because what constitutes "4G" has not yet been standardized. The ITU is currently considering candidate technologies for inclusion in the 4G IMT-Advanced standard, including LTE, UMB, and WiMAX II. Goals for 4G include data rates of least 100 Mbps, use of OFDMA transmission, and packet-switched delivery of IP-based voice, data, and streaming multimedia.

World’s Most Expensive Cars

What is the most expensive car in the world? The 1931 Bugatti Royale Kellner Coupe was sold for $8,700,000 in 1987. However, that car and many alike will not be included in this list because it is not available on the market today. It is hard to imagine someone would actually spend 8 million dollars on a car instead of using it for something more productive. However, if you have the money and the opportunity, you will definitely spend a small fraction of it to place a few of these supercars in your garage. Here is the 10 most expensive cars available on the market.

1. Bugatti Veyron $1,192,057. This is by far the most expensive street legal car available on the market today. It is the fastest accelerating car reaching 0-60 in 2.5 seconds.

This baby cost nearly half as much as the Bugatti Veyron, yet has enough power to top the most expensive car in a speed race. It is estimated that only 25 of this exact model will ever be produced.


4. LeBlanc Mirabeau $645,084 Doesn’t this look like a race car? Yet, with $645k, you can get this car and legally drive to your local supermarket and buy groceries. It has a top speed of 229 mph+ and although it was intentionally made for racing, it may be bought and show off to your neighbors.

5. Saleen S7 Twin Turbo $555,000 The first true American production certified supercar, this cowboy is rank #4 for the fastest car in the world. It has a top speed of 248 mph+ and it can reach 0-60 in 3.2 seconds. If you are a true American patriot, you can be proud to show off this car.


6. Koenigsegg CCX $545,568 Swedish made, the Koenigsegg is fighting hard to become the fastest car in the world. Currently the 3rd fastest car in the world with a top speed of 250 mph+, the car manufacture Koenigsegg is not giving up and will continue to try and produce the fastest car.


7. Mercedes-Benz SLR McLaren $457,250 A GT supercar, the SLR McLaren is the fastest automatic transmission car in the world with a top speed of 207 mph+ and reaching 60 mph in 3.8 seconds from stand still point.

9. Maybach 62 $385,250 The first 4-doors sedan to make the list, the Maybach 62 includes many luxurious features and it was made for comfort rather than speed.





10. Maybach 57 S $367,000 High-end luxury saloon with sporty handling and top performance technology.

Best 10 Tips for Maintaining Car Engine


Car Engine maintenance is one of the most essential car care activity that requires huge investment, an investment that pays off with enhanced fuel efficiency and longer engine life.
The most common cause of various engine problems is overheating. This is one such factor that contributes to various engine issues like overheated engine, engine surges, strange engine sounds, engine hesitation, and more fuel consumption. This key contributing factor and various problems are directly linked to the condition of engine components that control the functioning of the car engine. The problems that occur in the engine directly influences the functioning and effectiveness of the car. Therefore, it is very important to take good care of the car engine.

Here are the best 10 tips for maintaining car engine:

1. Engine oil is the most element of a car engine that plays a vital role in car performance. It should be changed periodically or after every 3,000 to 6,000 miles. Also check the oil level and refill the tank if the level is low.

2. Check the condition of the air filter. If you find any kind of dirt or crack in the air filter, immediately replace it or else it would hamper the functioning of the car engine.

3. Whenever you decide to replace engine parts, ensure that you use original components. Faulty and fake engine components may damage the engine completely if they don't fit in well or are not reliable.

4. Use clean fuel for your car. Adding a fuel stabilizer to the engine can also be helpful for preventing gas from going stale.

5. For proper functioning of the car engine you also need to check the condition of the car battery.

6. The battery case should be free from dirt and cracks. If in case you find any leakage or dust on the surface of the battery case, replace the battery immediately.

7. A car engine also comprises a timing belt that runs the engine and some even comprise a serpentine belt that runs various pumps and accessories in the car. If you find wear and tear of these belts, then you should replace them or else it would hamper the efficiency of the car engine.

8. Ensure that all the car fluids including the brake fluid, engine fluid,engine coolant, power steering fluid, and transmission fluid are topped up to the marked level. Ensuring that all fluid levels are topped off can maintain the health of your engine.

9. Inspect the condition of the spark plug and if required change them. Damaged or ineffective spark plugs hamper the performance of the car engine and also prevents costly engine repairs.

10. If in case you find any kind of strange noises from the engine, get it checked from the mechanic and make sure that the necessary repair is done.

Windows XP New Tips & Tricks for Expert Users

In this Document I have a collection of Tips and Tricks which no body normally knows but it will be useful for EXPERT WINDOWS USERS not for beginners, the secrets which Microsoft is afraid to tell the people, the information which you will seldom find all gathered up and arranged in a single file. To fully reap this Manual you need to have a basic understanding of the Windows Registry, as almost all the Tricks and Tips involve this file.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Important Note: Before you read on, you need to keep one thing in mind. Whenever you make changes to the Windows Registry you need to Refresh it before the changes take place. Simply press F5 to refresh the registry and enable the changes. If this does not work Restart your system

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Exiting Windows the Cool and Quick Way

Normally it takes a hell lot of time just Shutting down Windows, you have to move your mouse to the Start Button, click on it, move it again over Shut Down, click, then move it over the necessary option and click, then move the cursor over the OK button and once again (you guessed it) click.This whole process can be shortened by creating shortcuts on the Desktop which will shut down Windows at the click of a button. Start by creating a new shortcut( right click and select New> Shortcut). Then in the command line box, type (without the quotes.)

'C:\windows\rundll.exe user.exe,exitwindowsexec'

This Shortcut on clicking will restart Windows immediately without any Warning. To create a Shortcut to Restarting Windows, type the following in the Command Line box:

'c:\windows\rundll.exe user.exe,exitwindows'

This Shortcut on clicking will shut down Windows immediately without any Warning.

Ban Shutdowns : A trick to Play on Lamers

This is a neat trick you can play on that lamer that has a huge ego, in this section I teach you, how to disable the Shut Down option in the Shut Down Dialog Box. This trick involves editing the registry, so please make backups. Launch regedit.exe and go to :

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

In the right pane look for the NoClose Key. If it is not already there then create it by right clicking in the right pane and selecting New > String Value.(Name it NoCloseKey ) Now once you see the NoCloseKey in the right pane, right click on it and select Modify. Then Type 1 in the Value Data Box.

Doing the above on a Win98 system disables the Shut Down option in the Shut Down Dialog Box. But on a Win95 machine if the value of NoCloseKey is set to 1 then click on the Start > Shut Down button displays the following error message:

This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.

This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.

Instead of performing the above difficult to remember process, simply save the following with an extension of .reg and add it's contents to the registry by double clicking on it.

REGEDIT4

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]

"NoClose"="1"

Disabling Display of Drives in My Computer

This is yet another trick you can play on your geek friend. To disable the display of local or networked drives when you click My Computer go to :

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Now in the right pane create a new DWORD item and name it NoDrives. Now modify it's value and set it to 3FFFFFF (Hexadecimal) Now press F5 to refresh. When you click on My Computer, no drives will be shown. To enable display of drives in My Computer, simply delete this DWORD item. It's .reg file is as follows:

REGEDIT4

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]

"NoDrives"=dword:03ffffff

Take Over the Screen Saver

To activate and deactivate the screen saver whenever you want, goto the following registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ScreenSavers

Now add a new string value and name it Mouse Corners. Edit this new value to -Y-N. Press F5 to refresh the registry. Voila! Now you can activate your screensaver by simply placing the mouse cursor at the top right corner of the screen and if you take the mouse to the bottom left corner of the screen, the screensaver will deactivate.

Pop a banner each time Windows Boots

To pop a banner which can contain any message you want to display just before a user is going to log on, go to the key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WinLogon

Now create a new string Value in the right pane named LegalNoticeCaption and enter the value that you want to see in the Menu Bar. Now create yet another new string value and name it: LegalNoticeText. Modify it and insert the message you want to display each time Windows boots. This can be effectively used to display the company's private policy each time the user logs on to his NT box. It's .reg file would be:

REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Winlogon]

"LegalNoticeCaption"="Caption here."

Delete the Tips of the Day to save 5KB

Windows 95 had these tips of the day which appeared on a system running a newly installed Windows OS. These tips of the day are stored in the Windows Registry and consume 5K of space. For those of you who are really concerned about how much free space your hard disk has, I have the perfect trick.

To save 5K go to the following key in Regedit:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Tips

Now simply delete these tricks by selecting and pressing the DEL key.

Change the Default Locations

To change the default drive or path where Windows will look for it's installation files, go to the key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Setup\SourcePath

Now you can edit as you wish.

Secure your Desktop Icons and Settings

You can save your desktop settings and secure it from your nerdy friend by playing with the registry. Simply launch the Registry Editor go to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

In the right pane create a new DWORD Value named NoSaveSettings and modify it's value to 1.

Refresh and restart for the settings to get saved.

CLSID Folders Explained

Don't you just hate those stubborn stupid icons that refuse to leave the desktop, like the Network Neighborhood icon. I am sure you want to know how you can delete them. You may say, that is really simple, simply right click on the concerned icon and select Delete. Well not exactly, you see when you right click on these special folders( see entire list below)neither the rename nor the delete option does not appear. To delete these folders, there are two methods, the first one is using the System Policy Editor(Poledit in the Windows installation CD)and the second is using the Registry.

Before we go on, you need to understand what CLSID values are. These folders, like the Control Panel, Inbox, The Microsoft Network, Dial Up Networking etc are system folders. Each system folder has a unique CLSID key or the Class ID which is a 16-byte value which identifies an individual object that points to a corresponding key in the registry.

To delete these system Folders from the desktop simply go to the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Desktop\Namespace{----}

To delete an icon simply delete the 16 byte CLSID value within "NameSpace". The following are the CLSID values of the most commonly used icons:

My Briefcase:{85BBD920-42AO-1069-A2E4-08002B30309D}

Desktop: {00021400-0000-0000-C000-0000000000046}

Control Panel:{21EC2020-3AEA-1069-A2DD-08002B30309D}

Dial-Up-Networking:{992CFFA0-F557-101A-88EC-00DD01CCC48}

Fonts: {BD84B380-8CA2-1069-AB1D-08000948534}

Inbox :{00020D76-0000-0000-C000-000000000046}

My Computer :{20D04FE0-3AEA-1069-A2D8-08002B30309D}

Network Neighborhood:{208D2C60-3AEA-1069-A2D7-O8002B30309D}

Printers :{2227A280-3AEA-1069-A2DE-O8002B30309D}

Recycle Bin :{645FF040-5081-101B-9F08-00AA002F954E}

The Microsoft Network:{00028B00-0000-0000-C000-000000000046}

History: {FF393560-C2A7-11CF-BFF4-444553540000}

Winzip :{E0D79300-84BE-11CE-9641-444553540000}

For example, to delete the Recycle Bin, first note down it's CLSID value, which is: 645FF040-5081-101B-9F08-00AA002F954E. Now go to the Namespace key in the registry and delete the corresponding key.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\Desktop\NameSpace\{645FF040-5081-101B-9F08-00AA002F954E}

Similarly to delete the History folder, delete the following key:


HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\Desktop\NameSpace\{FBF23B42-E3F0-101B-8488-00AA003E56F8}

Hide all icons from the desktop

Sometimes, you may need to play a trick on your brother or friend, well this one teaches you how to hide all icons from the Desktop. Go to the following registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

In the right pane create a new DWORD value by the name: NoDesktop and set its value to: 1. Reboot and you will find no icons on the desktop.


Adding options to the right click context menus


Till now you simply learnt how to delete the special system folders by deleting a registry key, but the h@*k would have been better if there was a way of adding the DELETE and RENAME option to the right click context menus of these special folders. You can actually change the right click context menu of any system folder and add any of the following options: RENAME, DELETE, CUT, COPY, PASTE and lots more.

This h@*k too requires you to know the CLSID value of the system folder whose menu you want to customize. In this section, I have taken up Recycle Bin as the folder whose context menu I am going to edit.

Firstly launch the registry editor and open the following registry key:

HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\ShellFolder.

In Case you want to edit some other folder like say the FONTS folder, then you will open the following key:

HKEY_CLASSES_ROOT\CLSID\{CLSID VALUE HERE}\ShellFolder.

In the right pane there will be a DWORD value names attributes. Now consider the following options:


1. To add the Rename option to the menu, change the value of Attributes to 50 01 00 20

2. To add the Delete option to the menu, change the value of Attributes to 60 01 00 20

3. To add both the Rename & Delete options to the menu, change the value of Attributes to 70,01,00,20

4. Add Copy to the menu, change Attributes to 41 01 00 20

5. Add Cut to the menu, change Attributes to 42 01 00 20

6. Add Copy & Cut to the menu, change Attributes to 43 01 00 20

7. Add Paste to the menu, change Attributes to 44 01 00 20

8. Add Copy & Paste to the menu, change Attributes to 45 01 00 20

9. Add Cut & Paste to the menu, change Attributes to 46 01 00 20

10.Add all Cut, Copy & Paste to the menu, change Attributes to 47 01 00 20

We want to add only the Rename option to the right click context menu of the Recycle Bin, so change the value of attributes to: 50 01 00 20. Press F5 to refresh and then after rebooting you will find that when you right click on the Recycle Bin a RENAME option pops up too.

To reset the default Windows options change the value of Attributes back to 40 01 00 20

The Registry File which one can create for the above process would be something like the below:

REGEDIT4

[HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\Shell-Folder]

"Attributes"=hex:50,01,00,20

Adding control panel options to start menu

To access say the Modem Properties in the Control Panel Folder, the normal procedure is: Click on Start, Click on Settings> Control Panel and then wait for the Control Panel window to pop up and then ultimately click on the Modems icon.

Wouldn't it be lovely if you could shorten the process to: Click on Start> Control Panel>Modems. Yes you can add the Control Panel and also all other Special System Folders directly to the first level Start Menu. Firstly collect the CLSID value of the folder you want to add to the start menu. I want to add Control Panel hence the CLSID value is: 21EC2020-3AEA-1069-A2DD-08002B30309D

Now right click on the Start Button and select Open. Now create a new folder and name it: Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}

NOTE: Do not forget the period after the 'l' in Panel. Similarly all system folders can be added to the Start Menu.(accept My Briefcase, I think)

Deleting System Options from the Start menu

You can actually remove the Find and Run options from the start menu by performing a simple registry h@*k. Again like always Launch the registry editor and scroll down to the below key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Right-click on the right pane and select New, DWORD Value. Name it NoFind.(To remove the RUN option name it NoRun). Double-click the newly create DWORD to edit it's value and enter 1 as its value. This will disable the FIND option of the Start Menu and will also disable the default Shortcut key(F3 for Find.)

To restore the Run or find command modify the value of the DWORD to 0 or simply Delete the DWORD value.

Fed Up of the boring Old Yellow Folder Icons?[Drive Icons Included]

NOTE: This trick hasn't been tried on Win98.

You can easily change the boring yellow folder icons to your own personalized icons. Simply create a text file and copy the following lines into it:

[.ShellClassInfo]

ICONFILE=Drive:\Path\Icon_name.extension

Save this text file by the name, desktop.ini in the folder, whose icon you want to change. Now to prevent this file from getting deleted change it's attributes to Hidden and Read Only by using the ATTRIB command.

To change the icon of a drive, create a text file containing the following lines:

[Autorun]

ICON=Drive:\Path\Icon_name.extension

Save this file in the root of the drive whose icon you want to change and name it autorun.inf For Example, if you want to change the icon of a floppy, SAVE THE icon in a:\icon_name.ico One can also create a kewl icon for the Hard Disk and create a text file [autorun.inf] and store it in "c:\".

Securing NT

By default, NT 4.0 displays the last person who logged onto the system. This can be considered to be a security threat, especially in the case of those who choose their password to be same as their Username. To disable this bug which actually is a feature, go to the following key in the registry editor:

HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Winlogon

Click and select the ReportBookOK item and create a new string value called DontDisplayLastUserName. Modify it and set it's value to 1.

As a system administrator, you can ensure that the passwords chosen by the users are not too lame or too easy to guess. NT has this lovely utility called the User Manager which allows the administrator to set the age limit of the password which forces the users to change the password after a certain number of days. You can also set the minimum length of passwords and prevent users to use passwords which already have been used earlier and also enable account lockouts which will deactivate an account after a specified number of failed login attempts.

When you log on to Win NT, you should disable Password Caching, this ensures Single NT Domain login and also prevents secondary Windows Logon screen.

Simply copy the following lines to a plain text ASCII editor like: Notepad and save it with an extension, .reg

----------------DISABLE.reg-----------------

REGEDIT4 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Network]

"DisablePwdCaching"=dword:00000001

----------------DISABLE.reg-----------------

To Enable Password Caching use the following .reg file:

--------------Enable.reg-----------------

REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Network]

"DisablePwdCaching"=dword:00000000

--------------Enable.reg-----------------

Cleaning Recent Docs Menu and the RUN MRU

The Recent Docs menu can be easily disabled by editing the Registry. To do this go to the following Key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Now in the right pane, create a new DWORD value by the name: NoRecentDocsMenu and set it's value to 1. Restart Explorer to save the changes.

You can also clear the RUN MRU history. All the listings are stored in the key:

HKEY_USERS\.Default\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU

You can delete individual listings or the entire listing. To delete History of Find listings go to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Doc Find Spec MRU

and delete.

Customizing the Right Click Context Menu of the Start Menu

When you right click on the start menu, only 3 options pop up: Open, Explore, and Find. You can add your own programs to this pop up menu( which comes up when we right click on it.) Open Regedit and go to the following registry key:

HKEY_CLASSES_ROOT\Directory\Shell

Right click on the shell and create a new Sub Key (You can create a new SubKey by right clicking on the Shell Key and selecting New > Key.). Type in the name of the application you want to add to the start menu. I want to add Notepad to the Start Menu and hence I name this new sub key, Notepad. Now right click on the new registry key that you just created and create yet another new key named Command. Enter the ful path of the application, in this case Notepad in the default value of Command in the right pane. So I Modify the value of the default string value and enter the ful pathname of Notepad:

c:\wndows\notepad.exe.

Now press F5 to refresh. Now if you right click on the Start Button you will find a new addition to the Pop Up Menu called Notepad. Clicking on it will launch Notepad.

We can not only add but also remove the existing options in this pop up box.

To delete the Find option, go to the following registry key:

HKEY_CLASSES_ROOT\Directory\Shell\Find

Delete Find. DO NOT delete Open else you will not be able to open any folders in the Start Menu like Programs, Accessories etc.

BMP Thumbnail As Icon

You can actually change the default BMP icon to a thumbnail version of the actual BMP file. To do this simply go to HKCU\Paint.Picture\Default. In the right pane change the value of default to %1. Please note however that this will slow down the display rate in explorer if there are too many BMP thumbnails to display. You can use other icons too, simply enter the pathname.To restore back to the normal change the vale of default back to: C:\Progra~1\Access~1\MSPAINT.EXE,1.

Customizing The Shortcut Arrow

All shortcuts have a tiny black arrow attached to it's icon to distinguish from normal files. This arrow can sometimes be pretty annoying and as a Hacker should know how to change each and everything, here goes another trick. Launch the Registry Editor and go to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\Shell Icons.

Now, on the right pane is a list of icons ( we found out that on some systems, Windows 98 especially, the right pane is blank. Don't worry, just add the value as required ). Find the value 29. If it isn't there, just add it. The value of this string should be C:\Windows\system\shell32.dll, 29 ( which means the 30th icon in shell32.dll - the first one begins with 0 ). Now, we need blank icon to do this. Just create one with white as the whole icon. Go here to learn how to create an icon. Once done just change the value to C:\.ico, 0 where "" is the ful path of the icon file and "0" is the icon in it.

Now for some fun. If the blank icon is a bit boring, change it again. You will find that under shell32.dll there is a gear icon, a shared folder ( the hand ) and much more. Experiment for yourself!

Use Perl to Get List or Services Running on your NT box

Use the following Perl Script to get a list of Services running on your NT system

--------------script.pl-----------------

#!c:\per\bin\perl.exe

use Win32::Service;

my ($key, %service, %status, $part);

Win32::Service::GetServices(' ',\%services);

foreach $key (sort keys %services) {

print "Print Name\t: $key, $services{$key}\n";

Win32::Service::GetStatus( ' ',$services{$key};

\%status);

foreach $part (keys %status) {

print "\t$part : $status{$part}\n" if($part eq "CurrentState");

}

Internet Explorer Tricks and Tips

Resizable ful Screen Toolbar

The ful Screen option increases the viewable area and makes surfing more enjoyable but sometimes we need the Toolbar but also need to have extra viewing area. Now this h@*k teaches you how to change the size of the Internet Explorer toolbar. This registry h@*k is a bit complicated as it involves Binary values, so to make it simple, I have included the following registry file which will enable the resizable option of the Internet Explorer toolbar which was present in the beta version of IE.

h@*king TRUTH: Internet Explorer 5 displays the friendly version of HTTP errors like NOT FOUND etc . They are aimed at making things easier for newbies. If you would rather prefer to see the proper error pages for the web server you're using, go to Tools, Internet Options and select the Advanced tab. Then scroll down and uncheck the Show friendly http errors box.

Making the Internet Explorer & the Explorer Toolbars Fancy

The Internet Explorer toolbar looks pretty simple. Want to make it fancy and kewl? Why not add a background image to it. To do this kewl h@*k launch the Windows Registry Editor and go to the following key:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\ Internet Explorer\Toolbar\.

Now in the right pane create a new String Value and name it BackBitmap and modify it's value to the path of the Bitmap you want to dress it up with by rightclicking on it and choosing Modify. When you reboot the Internet Explorer and the Windows Explorer toolbars will have a new look.

Change Internet Explorer's Caption

Don't like the caption of Internet Explorer caption? Want to change it? Open the registry editor and go to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main.

In the right pane create a new String Value names Window Title (Note the space between Window and Title). Right click on this newly created String Value and select Modify. Type in the new caption you want to be displayed. Restart for the settings to take place.

Outlook Express Tricks

Colorful Background

Don't like the boring background colors of Outlook Express? To change it launch the Windows Registry Editor and scroll down to the

HKEY_CURRENT_USER\Software\Microsoft\Internet Mail And News key.

On the left pane, click on ColorCycle or select Edit and Modify in the menu. Now change the value to 1. Close and restart. Now, launch Outlook Express and whenever you open up a New Message, hold down ctrl-shift and tap the z key to scroll to change the background color. Repeat the keystroke to cycle through the colors.

Internet Explorer 5 Hidden Features

Microsoft Internet Explorer 5 has several hidden features which can be controlled using the Windows Registry. Open your registry and scroll down to the following key:

HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\Restrictions

Create a new DWORD value named x(See complete list of values of x below) and modify it's value to 1 to enable it and to 0 to disable it.

NoBrowserClose : Disable the option of closing Internet Explorer.

NoBrowserContextMenu : Disable right-click context menu.

NoBrowserOptions : Disable the Tools / Internet Options menu.

NoBrowserSaveAs : Disable the ability to Save As.

NoFavorites : Disable the Favorites.

NoFileNew : Disable the File / New command.

NoFileOpen : Disable the File / Open command.

NoFindFiles : Disable the Find Files command.

NoSelectDownloadDir : Disable the option of selecting a download directory.

NoTheaterMode : Disable the ful Screen view option.

h@*king Secrets

Almost all system administrators make certain changes and make the system restricted. System Administrators can hide the RUN option, the FIND command, the entire Control Panel, drives in My Computer like D: A: etc. They can even restrict activities of a hacker my disabling or hiding, even the tiniest options or tools.

Most commonly these restrictions are imposed locally and are controlled by the Windows Registry. But sometimes the smart system administrators control the activities of the hacker by imposing restrictions remotely through the main server.

Poledit or Policy Editor is a small kewl tool which is being commonly used by system administrators to alter the settings of a system. This utility is not installed by default by Windows. You need to install in manually from the Windows 98 Installation Kit from the Resource Kit folder. user.dat file that we saw earlier.

The Policy Editor tool imposes restrictions on the user's system by editing the user.dat file which in turn means that it edits the Windows Registry to change the settings. It can be used to control or restrict access to each and every folder and option you could ever think of. It has the power to even restrict access to individual folders, files, the Control Panel, MS DOS, the drives available etc. Sometimes this software does make life really hard for a Hacker. So how can we remove the restrictions imposed by the Policy Editor? Well read ahead to learn more.

You see the Policy Editor is not the only way to restrict a user's activities. As we already know that the Policy Editor edits the Windows Registry(user.dat) file to impose such restrictions. So this in turn would mean that we can directly make changes to the Windows Registry using a .reg file or directly to remove or add restrictions.

Launch Regedit and go to the following Registry Key:

HKEY_CURRENT_USER/Software/Microsoft/CurrentVersion/Policies

Under this key, there will definitely be a key named explorer. Now under this explorer key we can create new DWORD values and modify it's value to 1 in order to impose the restriction. If you want to remove the Restriction, then you can simply delete the respective DWORD values or instead change their values to 0. The following is a list of DWORD values that can be created under the Explorer Key-:

NoDeletePrinter: Disables Deletion of already installed Printers

NoAddPrinter: Disables Addition of new Printers

NoRun : Disables or hides the Run Command

NoSetFolders: Removes Folders from the Settings option on Start Menu (Control Panel, Printers, Taskbar)

NoSetTaskbar: Removes Taskbar system folder from the Settings option on Start Menu

NoFind: Removes the Find Tool (Start >Find)

NoDrives: Hides and does not display any Drives in My Computer

NoNetHood: Hides or removes the Network Neighborhood icon from the desktop

NoDesktop: Hides all items including, file, folders and system folders from the Desktop

NoClose: Disables Shutdown and prevents the user from normally shutting down Windows.

NoSaveSettings: Means to say, 'Don't save settings on exit'

DisableRegistryTools: Disable Registry Editing Tools (If you disable this option, the Windows Registry Editor(regedit.exe) too will not work.)

NoRecentDocsHistory: Removes Recent Document system folder from the Start Menu (IE 4 and above)

ClearRecentDocsOnExit: Clears the Recent Documents system folder on Exit.

Nolnternetlcon: Removes the Internet (system folder) icon from the Desktop

Under the same key: HKEY_CURRENT_USER/Software/Microsoft/CurrentVersion/Policies you can create new subkeys other than the already existing Explorer key. Now create a new key and name it System. Under this new key, system we can create the following new DWORD values(1 for enabling the particular option and 0 for disabling the particular option):

NODispCPL: Hides Control Panel

NoDispBackgroundPage: Hides Background page.

NoDispScrsavPage: Hides Screen Saver Page

NoDispAppearancePage: Hides Appearance Page

NoDispSettingsPage: Hides Settings Page

NoSecCPL: Disables Password Control Panel

NoPwdPage: Hides Password Change Page

NoAdminPaqe: Hides Remote Administration Page

NoProfilePage: Hides User Profiles Page

NoDevMgrPage: Hides Device Manager Page

NoConfigPage: Hides Hardware Profiles Page

NoFileSysPage: Hides File System Button

NoVirtMemPage: Hides Virtual Memory Button

Similarly, if we create a new subkey named Network, we can add the following DWORD values under it(1 for enabling the particular option and 0 for disabling the particular option):

NoNetSetupSecurityPage: Hides Network Security Page

NoNelSetup: Hides or disables the Network option in the Control Panel

NoNetSetupIDPage: Hides the Identification Page

NoNetSetupSecurityPage: Hides the Access Control Page

NoFileSharingControl: Disables File Sharing Controls

NoPrintSharing: Disables Print Sharing Controls

Similarly, if we create a new subkey named WinOldApp, we can add the following DWORD values under it(1 for enabling the particular option and 0 for disabling the particular option):

Disabled: Disable MS-DOS Prompt

NoRealMode: Disable Single-Mode MS-DOS.

So you see if you have access to the Windows Registry, then you can easily create new DWORD values and set heir value to 1 for enabling the particular option and 0 for disabling the particular option. But Sometimes, access to the Windows Registry is blocked. So what do you do? Go to the Windows Directory and delete either user.dat or system.dat (These 2 files constitute the Windows Registry.) and reboot. As soon as Windows logs in, it will display a Warning Message informing you about an error in the Windows Registry. Simply ignore this Warning Message and Press CTRL+DEL+ALT to get out of this warning message.(Do not press OK) You will find that all restrictions have been removed.

The most kind of restriction found quite commonly is the Specific Folder Restriction, in which users are not allowed access to specific folders, the most common being the Windows folder, or sometimes even access to My Computer is blocked. In effect, you simply cannot seem to access the important kewl files which are needed by you to do remove restrictions. What do you? Well use the RUN command. (START >RUN). But unfortunately a system administrator who is intelligent enough to block access to specific folder, would definitely have blocked access to the RUN command. Again we are stuck.

Windows is supposed to be the most User Friendly Operating System on earth. (At least Microsoft Says so.)

It gives the User an option to do the same thing in various ways. You see the RUN command is only the most convenient option of launching applications, but not the only way. In Windows you can create shortcuts to almost anything from a file, folder to a Web URL. So say your system administrator has blocked access to the c:\windows\system folder and you need to access it. What do you do? Simply create a Shortcut to it. To do this right click anywhere on the desktop and select New > Shortcut. A new window titled Create Shortcut pops up. Type in the path of the restricted folder you wish to access, in this case c:\windows\system. Click Next, Enter the friendly name of the Shortcut and then click Finish. Now you can access the restricted folder by simply double clicking on the shortcut icon. Well that shows how protected and secure *ahem Windows *ahem is

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

h@*king TRUTH: Sometimes when you try to delete a file or a folder, Windows displays an error message saying that the file is protected. This simply means that the file is write protected, or in other words the R option is +. Get it? Anyway, you can stop Windows from displaying this error message and straightaway delete this file by changing its attributes to Non Read Only. This can be done by Right Clicking on the file, selecting Properties and then unselecting the Read Only Option.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There is yet another way of accessing restricted folders. Use see, DOS has a lovely command known as START. Its general syntax is:

START application_path

It does do what it seems to do, start applications. So in you have access to DOS then you can type in the START command to get access to the restricted folder. Now mostly access to DOS too would be blocked. So again you can use the shortcut trick to launch, c:\command.com or c:\windows\command.com. (Command.com is the file which launches MS DOS).

Accessing Restricted Drives

The problem with most system administrators is that they think that the users or Hackers too are stupid. Almost all system administrators use the Registry Trick (Explained Earlier) to hide all drives in My Computer. So in order to unhide or display all drives, simply delete that particular key.(Refer to beginning of Untold Secrets Section.)

Some systems have the floppy disk disabled through the BIOS. On those systems if the BIOS is protected, you may need to cr@ck the BIOS password. (For that Refer to the Windows h@*king Chapter). Sometimes making drives readable (Removing R +) and then creating Shortcuts to them also helps us to get access to them.

Further Changing your Operating System's Looks by editing .htt files

If you have installed Windows Desktop Update and have the view as Web Page option enabled, you can customise the way the folder looks by selecting View > Customise this folder. Here you can change the background and other things about that particular folder. Well that is pretty lame, right? We hackers already know things as lame as that. Read on for some kewl stuff.

Well, you could also change the default that is stored in a Hidden HTML Template file (I think so..) which is nothing but a HTML document with a .htt extension. This .htt file is found at: %systemroot%\web\folder.htt.

The %systemroot% stands for the drive in which Windows is Installed, which is normally C:

You can edit these .htt files almost just like you edit normal .HTM or .HTML files. Simply open them in an ASCII editor like Notepad. The following is a list of .htt files on your system which control various folders and which can be edited to customise the way various folders look.

controlp.htt Control Panel

printers.htt Printers

mycomp.htt My Computer

safemode.htt Safe Mode

All these files are found in the web folder in %systemfolder%. The folder.htt file has a line:

'Here's a good place to add a few lines of your own"

which is the place where you can add your own A HREF links. These links would then appear in the folder whose folder.htt file you edited. All this might sound really easy and simple, but you see these .htt files do not contain normal HTML code, instead they contain a mixture of HTML and web bots. Hence they can be difficult for newbies to understand.

Sir Galileo Galilei (1564 - 1642)


Born: 15 Feb 1564 in Pisa (now in Italy)
Died: 8 Jan 1642 in Arcetri (near Florence) (now in Italy)


Galileo Galilei was an Italian natural philosopher, astronomer, and mathematician who made fundamental contributions to the sciences of motion, astronomy, and strength of materials and to the development of the scientific method.
His formulation of (circular) inertia, the law of falling bodies, and parabolic trajectories marked the beginning of a fundamental change in the study of motion.
His insistence that the book of nature was written in the language of mathematics changed natural philosophy from a verbal, qualitative account to a mathematical one in which experimentation became a recognized method for discovering the facts of nature.
Finally, his discoveries with the telescope revolutionized astronomy and paved the way for the acceptance of the Copernican heliocentric system, but his advocacy of that system eventually resulted in an Inquisition process against him.


Early life and career

Galileo was born in Pisa, Tuscany, on February 15, 1564, the oldest son of Vincenzo Galilei, a musician who made important contributions to the theory and practice of music and who may have performed some experiments with Galileo in 1588-89 on the relationship between pitch and the tension of strings.
The family moved to Florence in the early 1570s, where the Galilei family had lived for generations. In his middle teens Galileo attended the monastery school at Vallombrosa, near Florence, and then in 1581 matriculated at the University of Pisa, where he was to study medicine.
However, he became enamoured with mathematics and decided to make the mathematical subjects and philosophy his profession, against the protests of his father. Galileo then began to prepare himself to teach Aristotelian philosophy and mathematics, and several of his lectures have survived.
In 1585 Galileo left the university without having obtained a degree, and for several years he gave private lessons in the mathematical subjects in Florence and Siena.
During this period he designed a new form of hydrostatic balance for weighing small quantities and wrote a short treatise, La bilancetta ("The Little Balance"), that circulated in manuscript form.
He also began his studies on motion, which he pursued steadily for the next two decades.
In 1588 Galileo applied for the chair of mathematics at the University of Bologna but was unsuccessful.
His reputation was, however, increasing, and later that year he was asked to deliver two lectures to the Florentine Academy, a prestigious literary group, on the arrangement of the world in Dante's Inferno.
He also found some ingenious theorems on centres of gravity (again, circulated in manuscript) that brought him recognition among mathematicians and the patronage of Guidobaldo del Monte (1545-1607), a nobleman and author of several important works on mechanics.
As a result, he obtained the chair of mathematics at the University of Pisa in 1589.
There, according to his first biographer, Vincenzo Viviani (1622-1703), Galileo demonstrated, by dropping bodies of different weights from the top of the famous Leaning Tower, that the speed of fall of a heavy object is not proportional to its weight, as Aristotle had claimed.
The manuscript tract De motu (On Motion), finished during this period, shows that Galileo was abandoning Aristotelian notions about motion and was instead taking an Archimedean approach to the problem.
But his attacks on Aristotle made him unpopular with his colleagues, and in 1592 his contract was not renewed.
His patrons, however, secured him the chair of mathematics at the University of Padua, where he taught from 1592 until 1610.
Although Galileo's salary was considerably higher there, his responsibilities as the head of the family (his father had died in 1591) meant that he was chronically pressed for money.
His university salary could not cover all his expenses, and he therefore took in well-to-do boarding students whom he tutored privately in such subjects as fortification.
He also sold a proportional compass, or sector, of his own devising, made by an artisan whom he employed in his house. Perhaps because of these financial problems, he did not marry, but he did have an arrangement with a Venetian woman, Marina Gamba, who bore him two daughters and a son.
In the midst of his busy life he continued his research on motion, and by 1609 he had determined that the distance fallen by a body is proportional to the square of the elapsed time (the law of falling bodies) and that the trajectory of a projectile is a parabola, both conclusions that contradicted Aristotelian physics.

Telescope Discoveries








At this point, however, Galileo's career took a dramatic turn.
In the spring of 1609 he heard that in the Netherlands an instrument had been invented that showed distant things as though they were nearby.
By trial and error, he quickly figured out the secret of the invention and made his own three-powered spyglass from lenses for sale in spectacle makers' shops.
Others had done the same; what set Galileo apart was that he quickly figured out how to improve the instrument, taught himself the art of lens grinding, and produced increasingly powerful telescopes.




In August of that year he presented an eight-powered instrument to the Venetian Senate (Padua was in the Venetian Republic).
He was rewarded with life tenure and a doubling of his salary.
Galileo was now one of the highest-paid professors at the university.
In the fall of 1609 Galileo began observing the heavens with instruments that magnified up to 20 times.
In December he drew the Moon's phases as seen through the telescope, showing that the Moon's surface is not smooth, as had been thought, but is rough and uneven.
In January 1610 he discovered four moons revolving around Jupiter.
He also found that the telescope showed many more stars than are visible with the naked eye.
These discoveries were earthshaking, and Galileo quickly produced a little book, Sidereus Nuncius (The Sidereal Messenger), in which he described them.
He dedicated the book to Cosimo II de Medici (1590-1621), the grand duke of his native Tuscany, whom he had tutored in mathematics for several summers, and he named the moons of Jupiter after the Medici family: the Sidera Medicea, or Medicean Stars Galileo was rewarded with an appointment as mathematician and philosopher of the grand duke of Tuscany, and in the fall of 1610 he returned in triumph to his native land.
Galileo was now a courtier and lived the life of a gentleman.
Before he left Padua he had discovered the puzzling appearance of Saturn, later to be shown as caused by a ring surrounding it, and in Florence he discovered that Venus goes through phases just as the Moon does.
Although these discoveries did not prove that the Earth is a planet orbiting the Sun, they undermined Aristotelian cosmology: the absolute difference between the corrupt earthly region and the perfect and unchanging heavens was proved wrong by the mountainous surface of the Moon, the moons of Jupiter showed that there had to be more than one centre of motion in the universe, and the phases of Venus showed that it (and, by implication, Mercury) revolves around the Sun.
As a result, Galileo was confirmed in his belief, which he had probably held for decades but which had not been central to his studies, that the Sun is the centre of the universe and that the Earth is a planet, as Copernicus had argued. Galileo's conversion to Copernicanism would be a key turning point in the scientific revolution.
After a brief controversy about floating bodies, Galileo again turned his attention to the heavens and entered a debate with Christoph Scheiner (1573-1650), a German Jesuit and professor of mathematics at Ingolstadt, about the nature of sunspots (of which Galileo was an independent discoverer).
This controversy resulted in Galileo's Istoria e dimostrazioni intorno alle macchie solari e loro accidenti ("History and Demonstrations Concerning Sunspots and Their Properties," or "Letters on Sunspots"), which appeared in 1613.
Against Scheiner, who, in an effort to save the perfection of the Sun, argued that sunspots are satellites of the Sun, Galileo argued that the spots are on or near the Sun's surface, and he bolstered his argument with a series of detailed engravings of his observations.


Galileo's Copernicanism

Galileo's increasingly overt Copernicanism began to cause trouble for him. In 1613 he wrote a letter to his student Benedetto Castelli (1528-1643) in Pisa about the problem of squaring the Copernican theory with certain biblical passages. Inaccurate copies of this letter were sent by Galileo's enemies to the Inquisition in Rome, and he had to retrieve the letter and send an accurate copy. Several Dominican fathers in Florence lodged complaints against Galileo in Rome, and Galileo went to Rome to defend the Copernican cause and his good name.
Before leaving, he finished an expanded version of the letter to Castelli, now addressed to the grand duke's mother and good friend of Galileo, the dowager Christina. In his Letter to the Grand Duchess Christina, Galileo discussed the problem of interpreting biblical passages with regard to scientific discoveries but, except for one example, did not actually interpret the Bible. That task had been reserved for approved theologians in the wake of the Council of Trent (1545-63) and the beginning of the Catholic Counter-Reformation.
But the tide in Rome was turning against the Copernican theory, and in 1615, when the cleric Paolo Antonio Foscarini (c. 1565-1616) published a book arguing that the Copernican theory did not conflict with scripture, Inquisition consultants examined the question and pronounced the Copernican theory heretical. Foscarini's book was banned, as were some more technical and nontheological works, such as Johannes Kepler's Epitome of Copernican Astronomy.
Copernicus's own 1543 book, De revolutionibus orbium coelestium libri vi ("Six Books Concerning the Revolutions of the Heavenly Orbs"), was suspended until corrected.
Galileo was not mentioned directly in the decree, but he was admonished by Robert Cardinal Bellarmine (1542-1621) not to "hold or defend" the Copernican theory.
An improperly prepared document placed in the Inquisition files at this time states that Galileo was admonished "not to hold, teach, or defend" the Copernican theory "in any way whatever, either orally or in writing."
Galileo was thus effectively muzzled on the Copernican issue.
Only slowly did he recover from this setback. Through a student, he entered a controversy about the nature of comets occasioned by the appearance of three comets in 1618.
After several exchanges, mainly with Orazio Grassi (1583-1654), a professor of mathematics at the Collegio Romano, he finally entered the argument under his own name Il saggiatore (The Assayer), published in 1623, was a brilliant polemic on physical reality and an exposition of the new scientific method. Galileo here discussed the method of the newly emerging science, arguing:
Philosophy is written in this grand book, the universe, which stands continually open to our gaze. But the book cannot be understood unless one first learns to comprehend the language and read the letters in which it is composed.
It is written in the language of mathematics, and its characters are triangles, circles, and other geometric figures without which it is humanly impossible to understand a single word of it.
He also drew a distinction between the properties of external objects and the sensations they cause in us - i.e., the distinction between primary and secondary qualities.
Publication of Il saggiatore came at an auspicious moment, for Maffeo Cardinal Barberini (1568-1644), a friend, admirer, and patron of Galileo for a decade, was named Pope Urban VIII as the book was going to press. Galileo's friends quickly arranged to have it dedicated to the new pope.
In 1624 Galileo went to Rome and had six interviews with Urban VIII. Galileo told the pope about his theory of the tides (developed earlier), which he put forward as proof of the annual and diurnal motions of the Earth. The pope gave Galileo permission to write a book about theories of the universe but warned him to treat the Copernican theory only hypothetically.
The book, Dialogo sopra i due massimi sistemi del mondo, tolemaico e copernicano (Dialogue Concerning the Two Chief World Systems, Ptolemaic & Copernican), was finished in 1630, and Galileo sent it to the Roman censor.
Because of an outbreak of the plague, communications between Florence and Rome were interrupted, and Galileo asked for the censoring to be done instead in Florence.
The Roman censor had a number of serious criticisms of the book and forwarded these to his colleagues in Florence.
After writing a preface in which he professed that what followed was written hypothetically, Galileo had little trouble getting the book through the Florentine censors, and it appeared in Florence in 1632.
In the Dialogue's witty conversation between Salviati (representing Galileo), Sagredo (the intelligent layman), and Simplicio (the dyed-in-the-wool Aristotelian), Galileo gathered together all the arguments (mostly based on his own telescopic discoveries) for the Copernican theory and against the traditional geocentric cosmology.
As opposed to Aristotle's, Galileo's approach to cosmology is fundamentally spatial and geometric: the Earth's axis retains its orientation in space as the Earth circles the Sun, and bodies not under a force retain their velocity (although this inertia is ultimately circular).
But in giving Simplicio the final word, that God could have made the universe any way he wanted to and still made it appear to us the way it does, he put Pope Urban VIII's favorite argument in the mouth of the person who had been ridiculed throughout the dialogue. The reaction against the book was swift.
The pope convened a special commission to examine the book and make recommendations; the commission found that Galileo had not really treated the Copernican theory hypothetically and recommended that a case be brought against him by the Inquisition.
Galileo was summoned to Rome in 1633.
During his first appearance before the Inquisition, he was confronted with the 1616 edict recording that he was forbidden to discuss the Copernican theory.
In his defense Galileo produced a letter from Cardinal Bellarmine, by then dead, stating that he was admonished only not to hold or defend the theory.
The case was at somewhat of an impasse, and, in what can only be called a plea bargain, Galileo confessed to having overstated his case.
He was pronounced to be vehemently suspect of heresy and was condemned to life imprisonment and was made to abjure formally.
There is no evidence that at this time he whispered, "Eppur si muove" ("And yet it moves").
It should be noted that Galileo was never in a dungeon or tortured; during the Inquisition process he stayed mostly at the house of the Tuscan ambassador to the Vatican and for a short time in a comfortable apartment in the Inquisition building.
After the process he spent six months at the palace of Ascanio Piccolomini (c. 1590-1671), the archbishop of Siena and a friend and patron, and then moved into a villa near Arcetri, in the hills above Florence. He spent the rest of his life there.
Galileo's daughter Sister Maria Celeste, who was in a nearby nunnery, was a great comfort to her father until her untimely death in 1634.
Galileo was then 70 years old. Yet he kept working. In Siena he had begun a new book on the sciences of motion and strength of materials.
There he wrote up his unpublished studies that had been interrupted by his interest in the telescope in 1609 and pursued intermittently since.
The book was spirited out of Italy and published in Leiden, Netherlands, in 1638 under the title Discorsi e dimostrazioni matematiche intorno a due nuove scienze attenenti alla meccanica Dialogues Concerning Two New Sciences.
Galileo here treated for the first time the bending and breaking of beams and summarized his mathematical and experimental investigations of motion, including the law of falling bodies and the parabolic path of projectiles as a result of the mixing of two motions, constant speed and uniform acceleration.
By then Galileo had become blind, and he spent his time working with a young student, Vincenzo Viviani, who was with him when he died on January 8, 1642.
