How To Use a Bluetooth Cell Phone connect to internet 

From Edzzy.i.ph blog i got this information and so interesting without internet connection through dial up or broadband you can access through the internet. This so nice for all who does not have an internet connection at home.

When no other means of connecting to the internet is available, mobile workers can use their blue tooth enabled cell phone as a modem.
An advantage to using blue tooth is your phone can remain in your laptop carrying case or pocket and blue tooth does not require direct line of sight connection.
If your laptop is not already blue tooth enabled, you can purchase a USB blue tooth adapter.

Time Required: 15 mins
Here’s How:

   1. Turn on the Bluetooth enabled cell phone and turn on the Bluetooth connection software.
   2. Make the phone discoverable.
   3. In Windows XP on the laptop go to My Bluetooth Places.
   4. Select View Devices in Range.
   5. After the discovery process is complete you should see the icon for the cell phone.
   6. Right-click on the icon and select Discover Available Services.
   7. To connect to your cell phone right-click on the Dial-Up Networking.
   8. Select Connect Dial-up networking.
   9. The phone will ask if you want to accept the connection request, decline or add to paired.
  10. The last step pairs the phone and laptop and performs the connection request.
  11. You will be prompted to enter a PIN code to pair up the devices, the PIN is entered in the cell phone.
  12. A dialogue box appears asking for user name, password and the phone number of your ISP.
  13. Click on the dial button to complete the connection.

Tips:

   1. To find devices in range you can click the Bluetooth menu and select Search for devices or open Entire Bluetooth Neighborhood and press F5.
   2. Pairing a phone and laptop will ensure the connection can be established whenever you require it and you don’t have to go through the set-up process each time. If you do not pair the two devices you will have to make the phone discoverable each time.

What You Need:

    * Bluetooth enabled cell phone
    * Bluetooth enabled laptop

2. Type CD C:\Windows\System to enter the Windows system folder on the hard drive.
3. Delete virus files by entering three different commands, DEL ska.exe, DEL ska.dll, DEL liste.ska, and DEL wsock32.dll.
4. Rename the virus modified wsock file by entering two commands, ATTRIB -r wsock32.dll and then REN wsock32.ska wsock32.dll.
5. Type WIN to start up Windows.
6. Click on the Start button and select "Run…" from the Start menu. Type REGEDIT and click on "OK" to run the Regedit program.
7. Click on plus symbol for each directory, in order: HKEY_LOCAL_MACHINE, Software, Microsoft, Windows, Current Version.
8. Click on "RunOnce" folder under the Current Version directory and see if there is a file titled "Ska.exe".
9. If Ska.exe is present in the RunOnce directory click on Ska.exe and press Delete on the keyboard.
10. Confirm the deletion (yes) of Ska.exe and select "Exit" from the Registry menu.
11. Locate and delete all copies of Happy99.exe (SKA) on the computer to avoid another infection. Diligently search email files and attachment folders.
12. Click on the Start menu and select "Files or Folders…" from the Find menu. Search for wsock32.dll on the "C" drive.
13. Right-click on the found wsock32.dll file and select Properties at the bottom of hte pop-up menu.

Start your Engine eight time faster that before

March 3, 2008

Up to 2x faster.

Eight-core processing power was once only top-of-the-line. Now it comes standard. This time around, performance is more phenomenal than ever — up to two times faster than the previous standard-configuration Mac Pro.¹ And with the multicore technology enhancements of Mac OS X Leopard, the new Mac Pro is a force to be reckoned with.

More power with less power.

Inside the new Mac Pro is the latest technology from Intel: Quad-Core Intel Xeon “Harpertown” processors. These processors run at blazingly fast speeds up to 3.2GHz. Based on the new 45-nm Intel Core microarchitecture, they deliver amazing performance but still maintain outstanding energy efficiency.

Cache count.

A huge amount of L2 cache — 12MB per processor — keeps frequently used data and instructions close to the processor cores and improves overall performance. 6MB of cache is shared between pairs of processor cores, allowing an individual core to use all the available shared cache at any one time.

Built at full tilt.

With the fastest Xeon architecture available, the new Mac Pro features 1600MHz dual independent frontside buses. These 64-bit buses give each processor a direct connection to the system controller and deliver improved processor bandwidth of up to 25.6GB per second — 20 percent greater than the previous Mac Pro. With a new system architecture, speedier system buses, and fast 800MHz DDR2 fully buffered DIMM memory, Mac Pro memory throughput is up to 1.6 times faster than before.

 

Dual-processor, Dual-core, and Multi-core: Keeping it straight

Dual core (DP) systems are those that contains two separate physical computer processors in the same chassis. In dual-processor systems, the two processors can either be located on the same motherboard or on separate boards.  In a dual-core configuration, an integrated circuit (IC) contains two complete computer processors. Usually, the two identical processors are manufactured so they reside side-by-side on the same die, each with its own path to the system front-side bus. Multi-core is somewhat of an expansion to dual-core technology and allows for more than two separate processors.

For software to take advantage of dual core architecture, it must be written to utilize parallel threading. Otherwise, the program functions in single-core mode, using just one data stream or one of the built-in microprocessors. Unfortunately, coding for TLP is quite intensive, as interleaving shared data can create errors and slow performance. Because of these and other issues, a dual core processor does not deliver twice the speed of a single-core processor, though there is a significant increase in performance under optimal conditions. Finally, dual core chips run hotter than their single-core cousins.
