Access Facebook on any Mobile Without the Internet

Do you have an old mobile phone, like the Nokia 1100, that has no browser and can do little more than make phone calls? Or are you stuck in some remote place where there’s no Internet or no other form of data (EGDE/GPRS/3G) connectivity is available?

Not a problem. You can still use your Facebook account in India by dialing *325# (or *fbk#) from your mobile phone – this service requires no data plan or Internet and it will even work on phones of the Stone Age. Here’s a quick tour:

        

Use Facebook without the Data Plan

Facebook India has partnered with Fonetwish to bring Facebook on every mobile phone without requiring any apps or even the Internet.

You dial the *325# number, then enter your Facebook username and password and you are in. You can then send number based commands to access various features of Facebook, chat with friends who are online, add new people to your friends list, and more.

I played with the service for some time and it was a nice experience overall. If there were a Unix-like shell interface for Facebook, it would be much similar. Fonetwish says that this service is currently available for Airtel, Aircel, Idea and Tata Docomo users in India.

It may be too much work to read your Facebook news feed stories one by one but this is a good option to quickly update your Facebook status or for chatting with friends who are online. The price is reasonable too – you just have pay a subscription fee of 1.00 per day for unlimited usage.

Related: If you have an old mobile phone, you can search Google by SMS without requiring a data plan.

Search Google on your Mobile Phone via SMS Text Messages

This is something for mobile phone users in India who don't have a web-enabled phone – you can now search for information on Google using SMS. The service has been around for a while but Google is no longer charging a premium fee for sending you the SMS message.

The Google SMS search service may be used for finding movie timings, weather, nearest pizza restaurant, currency conversion, train schedules, cricket scores and a host of other things.

One of the very useful features in SMS search is language translation. For instance, I could SMS "say hello in French" to 9-77-33-00000 to get the right French word.

Google SMS Search could be real bad news for the business of services like Indiatimes that charge a premium fee for delivering news or astrology updates on the mobile phone using short codes.

For details go to the Google Mobile website or check their help center for more details.

The Google blog says that you only need to pay the standard SMS text charges for sending the SMS query to Google – there's no fee for the incoming messages from Google. The service is available for all popular cellular networks including Airtel, BSNL, Idea, Reliance, Spice, Tata Indicom and Vodafone.

Difference between: Full, Differential, and Incremental Backup

Submitted by Laxman (chinnilax@gmail.com)

Type	Definition	Benefits	Drawbacks
Full Backup:	A complete backup of everything you want to backup.	Restoration is fast, since you only need one set of backup data.	The backing up process is slow. High storage requirements.
Differential Backup:	The backup software looks at which files have changed since you last did a full backup. Then creates copies of all the files that are different from the ones in the full backup. If you do a differential backup more than once, it will copy all the files, or parts of files that have changed since the last full backup, even if you already have identical copies of those files in a previous differential backup. For restoring all the data, you will only need the the last full backup, and the last differential backup.	Faster to create than a full backup. Restoration is faster than using incremental backup. Not as much storage needed as in a full backup.	Restoration is slower than using a full backup. Creating a differential backup is slower than creating an incremental backup.
Incremental Backup:	The backup software creates copies of all the files, or parts of files that have changed since previous backups of any type (full, differential or incremental). For example if you did a full backup on Sunday. An incremental backup made on Monday, would only contain files changed since Sunday, and an incremental backup on Tuesday, would only contain files changed since Monday, and so on.	This method is the fastest when creating a backup. The least storage space is needed.	Restoring from incremental backups is the slowest because it may require several sets of data to fully restore all the data. For example if you had a full backup and six incremental backups. To restore the data would require you to process the full backup and all six incremental backups.

How To Reinstall Windows Without Losing Your Data

The Windows XP installation CD includes an option to repair an existing Windows XP installation. Using this option allows you to reinstall Windows without losing the files, personal data and programs you already have on the system. To take advantage of it, just place the CD into your CD or DVD drive on your PC and reboot the computer.

During the installation you will be prompted if you wish to use the recovery console to repair a Windows installation. The recovery console is rather limited in its use, so just press the Enter key to proceed with the installation as you would normally.

Press F8 to continue past the Licensing Agreement.

The next screen should display a prompt asking you if you wish to repair an existing installation.  Select your Windows installation (most likely it is the only one) and press R.

This will begin the repair and reinstallation of Windows. The installation will copy files to the hard drive, reboot the system, and then proceed just like a normal installation. Follow the prompts just as you normally would any normal Windows installation.

When the installation completes, you should still be able to access all of your documents and installed programs.

Full Windows Reinstall Without Loosing Data and Programs

I personally prefer to perform a full clean reinstallation of Windows. With the clean install, the hard drive is formatted and programs are reinstalled. If you want to use this method, you can use the Files and Settings Transfer Wizard (AKA FAST).

Click here

To use FAST, you first have to run it from the old Windows installation. Click Start > All Programs > Accessories > System Tools > Files and Settings Transfer Wizard.

Tell FAST that you are on the Old Computer, then click Next.

Finally, select the location where you would wish to save the files.  Portable USB drives were born for stuff like this.  Be warned though, the drive may not be big enough.  Another option would be to save the settings somewhere on your hard drive first, and then move them over to multiple USB drives or burn them to CDs/DVDs.

Click Next, and wait for the files to be copied. If you have a lot of data, it may take quite a while for the process to complete.  Once it has completed, your settings are ready for the new installation.

Once you’ve reinstalled Windows, launch FAST just as you did initially to save your settings:

Start > All Programs > Accessories > System Tools > Files and Settings Transfer Wizard.  Click Next. This time when prompted which computer you are using, select New computer. Click Next.

The following screen will ask you if you have a Windows XP installation CD for creating a wizard disk.  A wizard disk can be used for loading settings from another computer. In this case, a wizard disk is not necessary since the files have been saved to another location.

Select I don’t need the Wizard Disk. I already have collected my files and settings from my old computer. Click Next to proceed.

Finally, you will be prompted for the location of the files and settings. Select the Otherradio button and browse to the location where you saved the files and click Next.

The files and settings will then be copied to the new computer. You may want to install all of the same programs you had on the old computer that you intend to use, before you run FAST. This will help to ensure that your settings will work properly with them.

How To Create An Unattended Windows XP Disk

An unattended XP disk is a customized installation disk that allows you to perform a Windows installation with minimal effort (once the disk is created). All of the effort takes place in creating the unattended disk, but it is well worth it. With an unattended XP disk, you can preselect all of the options you wish to use for the installation.

When you proceed with an unattended installation, you do still have to manually select the drive where you wish to install Windows (during the blue screen portion of the setup). However, once you’ve done that and started the installation you can walk away, grab a cup of coffee, eat some french toast, brush your teeth, check the weather, and by the time you get back you’ll see your new Windows XP desktop.

To create an unattended disk, you will of course need a Windows XP installation disk. You will also need to download nLite. nLite is a free program that allows you to create customized XP installation disks. Customizations you can perform include the integration of service packs, Windows updates, addition of drivers, preselection of installation options, preselection of components to install, and even more.

As a first step to unattended windows setup reference, you will need to get the latest Windows XP updates for your installation disk. Which updates you will need depends on how old your installation disk is. If you have a very old disk, you may need to download service pack 3 in addition to the updates that have taken place since the release of service pack 3. In the installation instructions below, you will learn how to find out whether or not Service Pack 3 is included on your installation disk.

Launch nLite, select your language, and click Next. Click the browse button to navigate to your the location of your installation CD. You will then be prompted for a location on the hard disk to store the files for processing. Select where you want to store the files and wait for the files to be copied.

Once the files have completed copying, nLite will detect what version of Windows XP is on the installation CD. If it says the installation has Service Pack 3, then you will not need to download the service pack. Otherwise you can download the service pack here. Proceed to the next step.

Since this is the first time you’ve run nLite, you will not have any presets. Just click Nextto advance to the Task Selection page. On the task selection page, select Hotfixes, Add-ons, and Update Packs, Unattended, and Bootable ISO. If you had to download Service Pack 3 because you have an older version, select Service Pack as well.

If you are feeling adventurous, you can also include Drivers, select Components for removal, select Options, and Tweaks as well. These are more advanced options that will not be discussed in this particular How-To. Click the Next button to proceed.

If you need to integrate Service Pack 3, you will advance to the Service Pack page. Select the location of where you downloaded Service Pack 3. Once you’re done, click Nextto advance to Hotfixes, Add-ons, and Update Packs.

Click the Insert button (in nLite, not on your keyboard) and navigate to the location of the update pack. Click Next to proceed to the Unattended settings. In order to avoid any interaction with the installation (other than selecting/formatting the hard drive in the blue screens), you will need to update the following:

• General Tab: Set Unattended Mode to Hide Pages
• General Tab: Enter your Product Key
• Users Tab: Password for the Administrator login (or check Blank password)
• User Tab: Add a new User and set the password (or check Blank password)
• User Tab: Set the Autologon to the new user you just added
• Owner and Network ID Tab: Computer Name
• Owner and Network ID Tab: Workgroup
• Owner and Network ID Tab: Full Name
• Owner and Network ID Tab: Organization
• Regional Tab: Timezone

Once you’ve updated those settings, and any others you would like to update, click Next. Continue when prompted if you would like to start the process. When the process is complete, click Next to proceed to the Bootable ISO section.

Under Mode, select whether you want to Create an Image or perform a Direct Burn to a CD. Direct Burn is probably the easier choice, because nLite will write it directly to disk. When you’ve made your selection click Make ISO. If you decide to burn to an image, use your favorite image burning software to write it to a disk.

That’s all there is to it! Just take the disk, pop it into the target machine, boot it up, select where you want to install/format, and then go take a little walk. Upon your return, your machine will have a fresh installation of Windows XP running on it!
