Marlboro then suddenly faltered badly in the market till the 1950s, when it made a rollicking comeback following the introduction of a new cowboy image for the brand. Sales skyrocketed by 5,000%. Marlboro with a filtered tip was launched in 1955.
Trick To Increase Browsing Speed for IE and Firefox
I shall be teaching you two tricks which work separately on Firefox and Internet Explorer. It doesn't require you to be some expert rather all you have to do is change some registry values and you are done. I have also included a video tutorial for those who want to see it step by step visually. This is perhaps one of the oldest tricks to optimize Firefox and IE but it still works great.
Trick to Increase Firefox Speed
1. Open Firefox and in the address bar write about:config and press enter
2. Double click network.http. pipelining and set it to True
3. Double click network.http. pipelining. maxrequests and set value to 10 from 4
4. Right click and create a new string nglayout.initialpai nt.delay and set its value to 0
You are done. Enjoy lightning fast Firefox browsing and now for IE.
Trick to Increase Internet Explorer Speed
1. Go to Start –> Run and type regedit
2. Select HKEY_CURRENT_ USER –> Software –> Microsoft –> Windows –> Current Version –> Internet Settings
3. Increase the values (DECIMAL) from default to a higher value e.g. 10
See the difference in speed of IE :D
Here you go with a step by step video tutorial

10 Reasons Why PCs Crash
You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening?
1 Hardware conflict
The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.
For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself.
If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:
Start-Settings- Control Panel-System- Device Manager.
Often if a device has a problem a yellow '!' appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it.
Sometimes a device might share an IRQ with something described as 'IRQ holder for PCI steering'. This can be ignored. The best way to fix this problem is to remove the problem device and reinstall it.
Sometimes you may have to find more recent drivers on the Internet to make the device function properly. A good resource is www.driverguide. com. If the device is a soundcard, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).
When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to discharge any static electricity.
To be fair to Mcft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out of them. There are plans to increase the number of IRQs in future designs.
2 Bad Ram
Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.
But a fatal error caused by Ram might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked.
One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged.
Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble.
EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmes.
3 BIOS settings
Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up.
Once inside the BIOS, great care should be taken. It is a good idea to write down on a piece of paper all the settings that appear on the screen. That way, if you change something and the computer becomes more unstable, you will know what settings to revert to.
A common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS latency of 3. Newer SDRam has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze the computer's display.
Mcft Windows is better at allocating IRQ numbers than any BIOS. If possible set the IRQ numbers to Auto in the BIOS. This will allow Windows to allocate the IRQ numbers (make sure the BIOS setting for Plug and Play OS is switched to 'yes' to allow Windows to do this.).
4 Hard disk drives
After a few weeks, the information on a hard disk drive starts to become piecemeal or fragmented. It is a good idea to defragment the hard disk every week or so, to prevent the disk from causing a screen freeze. Go to
Start-Programs- Accessories- System Tools-Disk Defragmenter
This will start the procedure. You will be unable to write data to the hard drive (to save it) while the disk is defragmenting, so it is a good idea to schedule the procedure for a period of inactivity using the Task Scheduler.
The Task Scheduler should be one of the small icons on the bottom right of the Windows opening page (the desktop).
Some lockups and screen freezes caused by hard disk problems can be solved by reducing the read-ahead optimisation. This can be adjusted by going to
Start-Settings- Control Panel-System Icon-Performance- File System-Hard Disk.
Hard disks will slow down and crash if they are too full. Do some housekeeping on your hard drive every few months and free some space on it. Open the Windows folder on the C drive and find the Temporary Internet Files folder. Deleting the contents (not the folder) can free a lot of space.
Empty the Recycle Bin every week to free more space. Hard disk drives should be scanned every week for errors or bad sectors. Go to
Start-Programs- Accessories- System Tools-ScanDisk
Otherwise assign the Task Scheduler to perform this operation at night when the computer is not in use.
5 Fatal OE exceptions and VXD errors
Fatal OE exception errors and VXD errors are often caused by video card problems.
These can often be resolved easily by reducing the resolution of the video display. Go to
Start-Settings- Control Panel-Display- Settings
Here you should slide the screen area bar to the left. Take a look at the colour settings on the left of that window. For most desktops, high colour 16-bit depth is adequate.
If the screen freezes or you experience system lockups it might be due to the video card. Make sure it does not have a hardware conflict. Go to
Start-Settings- Control Panel-System- Device Manager
Here, select the + beside Display Adapter. A line of text describing your video card should appear. Select it (make it blue) and press properties. Then select Resources and select each line in the window. Look for a message that says No Conflicts.
If you have video card hardware conflict, you will see it here. Be careful at this point and make a note of everything you do in case you make things worse.
The way to resolve a hardware conflict is to uncheck the Use Automatic Settings box and hit the Change Settings button. You are searching for a setting that will display a No Conflicts message.
Another useful way to resolve video problems is to go to
Start-Settings- Control Panel-System- Performance- Graphics
Here you should move the Hardware Acceleration slider to the left. As ever, the most common cause of problems relating to graphics cards is old or faulty drivers (a driver is a small piece of software used by a computer to communicate with a device).
Look up your video card's manufacturer on the internet and search for the most recent drivers for it.
6 Viruses
Often the first sign of a virus infection is instability. Some viruses erase the boot sector of a hard drive, making it impossible to start. This is why it is a good idea to create a Windows start-up disk. Go to
Start-Settings- Control Panel-Add/Remove Programs
Here, look for the Start Up Disk tab. Virus protection requires constant vigilance.
A virus scanner requires a list of virus signatures in order to be able to identify viruses. These signatures are stored in a DAT file. DAT files should be updated weekly from the website of your antivirus software manufacturer.
An excellent antivirus programme is McAfee VirusScan by Network Associates ( www.nai.com). Another is Norton AntiVirus 2000, made by Symantec ( www.symantec. com).
7 Printers
The action of sending a document to print creates a bigger file, often called a postscript file.
Printers have only a small amount of memory, called a buffer. This can be easily overloaded. Printing a document also uses a considerable amount of CPU power. This will also slow down the computer's performance.
If the printer is trying to print unusual characters, these might not be recognised, and can crash the computer. Sometimes printers will not recover from a crash because of confusion in the buffer. A good way to clear the buffer is to unplug the printer for ten seconds. Booting up from a powerless state, also called a cold boot, will restore the printer's default settings and you may be able to carry on.
8 Software
A common cause of computer crash is faulty or badly-installed software. Often the problem can be cured by uninstalling the software and then reinstalling it. Use Norton Uninstall or Uninstall Shield to remove an application from your system properly. This will also remove references to the programme in the System Registry and leaves the way clear for a completely fresh copy.
The System Registry can be corrupted by old references to obsolete software that you thought was uninstalled. Use Reg Cleaner by Jouni Vuorio to clean up the System Registry and remove obsolete entries. It works on Windows 95, Windows 98, Windows 98 SE (Second Edition), Windows Millennium Edition (ME), NT4 and Windows 2000.
Read the instructions and use it carefully so you don't do permanent damage to the Registry. If the Registry is damaged you will have to reinstall your operating system. Reg Cleaner can be obtained from www.jv16.org
Often a Windows problem can be resolved by entering Safe Mode. This can be done during start-up. When you see the message "Starting Windows" press F4. This should take you into Safe Mode.
Safe Mode loads a minimum of drivers. It allows you to find and fix problems that prevent Windows from loading properly.
Sometimes installing Windows is difficult because of unsuitable BIOS settings. If you keep getting SUWIN error messages (Windows setup) during the Windows installation, then try entering the BIOS and disabling the CPU internal cache. Try to disable the Level 2 (L2) cache if that doesn't work.
Remember to restore all the BIOS settings back to their former settings following installation.
9 Overheating
Central processing units (CPUs) are usually equipped with fans to keep them cool. If the fan fails or if the CPU gets old it may start to overheat and generate a particular kind of error called a kernel error. This is a common problem in chips that have been overclocked to operate at higher speeds than they are supposed to.
One remedy is to get a bigger better fan and install it on top of the CPU. Specialist cooling fans/heatsinks are available from www.computernerd. com or www.coolit.com
CPU problems can often be fixed by disabling the CPU internal cache in the BIOS. This will make the machine run more slowly, but it should also be more stable.
10 Power supply problems
With all the new construction going on around the country the steady supply of electricity has become disrupted. A power surge or spike can crash a computer as easily as a power cut.
If this has become a nuisance for you then consider buying a uninterrupted power supply (UPS). This will give you a clean power supply when there is electricity, and it will give you a few minutes to perform a controlled shutdown in case of a power cut.
It is a good investment if your data are critical, because a power cut will cause any unsaved data to be lost.

Wubi - Install Ubuntu inside Windows w/o Partitioning
If you want to install ubuntu 7.04 Feisty, but you don't want to modify your Windows partition and you want to install it inside, http://wubi- installer. org/ is for you. According to its website:
Wubi is an unofficial Ubuntu installer for Windows users that will bring you into the Linux world with a few clicks. Wubi allows you to install and uninstall Ubuntu as any other application. If you heard about Linux and Ubuntu, if you wanted to try them but you were afraid, this is for you.
Moreover, Wubi doesn't need you to replace the default Windows bootloader, as "Wubi adds an entry to the Windows boot menu which allows you to run Linux. Ubuntu is installed within a file in the windows file system (c:\wubi\disks\ system.virtual. disk), this file is seen by Linux as a real hard disk." Then it loads the file as a loopback root Filesystem, kind like those described in "The Loopback Root Filesystem HOWTO," but with the loopback filesystem is actually in Windows's partition.
Since Wubi makes Ubuntu run inside Windows partition, there will be a little bit performance penalty, especially when your Windows partition is fragmented. Moreover, if there were any error in the ntfs partition that affects the system virtual disk, you need to fix the errors with something like chkdsk in Windows first before booting Ubuntu. If you're not afraid of partitioning, I still recommend you to install Ubuntu in a separate partition.

Troubleshooting Windows Defender in Vista
Cannot Update Windows Defender !?
If you ever encounter an error code (e.g. "error code 0x80240029 - cannot update" which btw is the most common one), when updating Defender, here is a solution which will help you. This usually happens if the distribution database is broken and needs to be re-created.
Here are the solutions to address the issue :
1) As far as Vista goes (don't know if this applies to XP) you can do this by clicking start > all programs > windows updates> change settings > uncheck Automatic Updates, Uncheck Recommended Updates and uncheck use Microsoft Update Service. This will switch from Microsoft Update back to using Windows Update.
Reboot. If it works for you fine; you can now reset the update settings to as they were earlier.
2) I also came across this download from Microsoft (Vista/XP). This actually FORCES defender to update !
3) To manually update Windows Defender visit Microsofts Malware Protection Center for instructions.
4) Lastly if none work, there is another way you can try this:
Boot into safe mode. Find the folder named Software Distribution.
Rename SoftwareDistributio n to SoftwareDistributio n.old OR Delete all its contents (FLUSH it !) Reboot. Now try to update the Defender (at this point a new SoftwareDistributio n folder will be created if you have renamed it).
Additional help can always be found at Microsofts Windows Defender HelpGroup .

Disable Indexing Service & Use a Better Substitute
In order to search through a hard drive faster, XP keeps a record of all files on the hard drive.
It sounds useful, but if you use Windows' search tool infrequently, the indexing service just constantly runs in the background without being taken advantage of and used.
Indexing can slow down actions as simple as opening or closing files. To disable this service, go to Start > Run and type services.msc. Double click "Indexing Services" and set the startup type to "Disabled".
If you want to search, there is a freeware program called Locate that can index 400GB of data in under 2 minutes and can perform instant searches.
File > Update Databases re-indexes all your drives, in case you miss where the indexing option is located. You should only re-index before a search. This way, system resources are used only when you actually need to perform a search.
In addition, you can use Task Scheduler (a.k.a. Scheduled Tasks) to run the shortcut named "Updtdb32" in place of using the "Update Database" option manually within the program.
For example, have the task run daily at a time you are not usually at your computer, such as early in the morning.
So, all the files that had been added, moved and changed from the previous day can be indexed. If you have this re-indexing task done daily, it only takes a few seconds each time it is done.
You can get to the task scheduler by going to Start > Run. Type %systemroot% Tasks, and hit enter. Double click on "Add Scheduled Task" and the wizard will help take you through the process of setting up a scheduled task.
Make sure you hit "Browse" when asked for what application you want to be run. Navigate to the folder where you have the "Updtdb32" shortcut. Other than that, creating the scheduled task should be fairly self-explanatory, thanks to the wizard.

About Linux
Linux is a free Unix-type operating system originally created by Linus Torvalds with the assistance of developers around the world. Developed under the GNU General Public License, the source code for Linux is freely available to everyone which is causing a major evolution in the world of computers. It outperforms other operating systems on similar hardware and is available on architectures ranging from a PDA to supercomputers.
A modern operating system like Linux is even easier to install and use than Microsoft® Windows™, especially given the reboot nightmares, viruses, worms, driver-update hassles and Service Pack annoyances that come with Microsoft® Windows™.
Linux and Open Source technologies have become the standard platform of choice for IT system deployment. Over seventy percent of the Internet is running on Open Source technologies and international vendors such as Sun, Novell and IBM are deploying Linux and Open Source.
With proven reliability, security by design and a world class reputation throughout the IT industry there really is no reason why you cannot move to Linux and freedom right now. Why wait for your next systems failure? Now is the time to start your move to Linux and Open Source.
Moving to the Linux platform does not require abandoning existing investments in Microsoft Windows applications and infrastructure. Linux runs on the same hardware and can run many of the Microsoft Windows applications, like OpenOffice. What makes this even more amazing is that Linux and Open Source applications are freely available to anyone who wishes to download them.
Why Move?
The big question for many corporate IT professionals and developers is "Why would I move from Windows to Linux?" Windows is well established in the enterprise computing space and applications currently deployed on Windows may be running just fine in their organisation.
However, many organisations are migrating from Windows and UNIX to the OSS Linux platform. They are moving in order to gain better business value, a greater choice of solutions, and richer capabilities for addressing their enterprise computing needs and abilities. This is what no proprietary vendor can do...
1. They don't have the hugely productive environment of KDE to program in.
2. They can't run development crews of the Open Source Community size without considerable investment.
3. They can't gather the input of thousands of users.
4. They can't design in such an open fashion as to remove all their hooks.
5. They can't make a product so extensible that it takes away their upgrade leverage.
6. They can't give it away for free.

How does satellite Internet operate
Satellite Internet does not use telephone lines or cable systems, but instead uses a satellite dish for two-way (upload and download) data communications. Upload speed is about one-tenth of the 500 kbps download speed. Cable and DSL have higher download speeds, but satellite systems are about 10 times faster than a normal modem.
Firms that offer or plan to offer two-way satellite Internet include StarBand, Pegasus Express, Teledesic and Tachyon. Tachyon service is available today in the United States, Western Europe and Mexico. Pegasus Express is the two-way version of DirecPC.
Two-way satellite Internet consists of:
* * Approximately a two-foot by three-foot dish
* * Two modems (uplink and downlink)
* * Coaxial cables between dish and modem
The key installation planning requirement is a clear view to the south, since the orbiting satellites are over the equator area. And, like satellite TV, trees and heavy rains can affect reception of the Internet signals.
Two-way satellite Internet uses Internet Protocol (IP) multicasting technology, which means up to 5,000 channels of communication can simultaneously be served by a single satellite. IP multicasting sends data from one point to many points (at the same time) by sending data in compressed format. Compression reduces the size of the data and the bandwidth. Usual dial-up land-based terrestrial systems have bandwidth limitations that prevent multicasting of this magnitude.
Some satellite-Internet service still requires you to have a dial-up or cable modem connection for the data you send to the Internet. The satellite data downlink is just like the usual terrestrial link, except the satellite transmits the data to your computer via the same dish that would allow you to receive a Pay-Per-View television program.
So, if you are in a rural area and you want broadband access to the Internet, satellite Internet may be for you!
