Windows was unable to find a certificate to log you on to the network>MyNetwork

I am able to connect to the internet(I can load pages, messenger, everything) through my router but windows is giving me the message"Windows was unable to find a certificate to log you on to the network -> MyNetwork".

"Windows was unable to find a certificate to log you on to the network>My Network"That's caused by improperly setting the encryption to WPA-RADIUS instead of WPA-PSK on the client. The router and the client are both trying to find a RADIUS server with which to authenticate. Since you don't have one, it complains using Microsoft techno babble. Change the encryption to WPA-PSK (pre-shared key) on both ends.

File Systems for Harddisk, which one to choose ?

There are two different file system formats compatible with Windows operating systemsNTFS and FAT 32 (MS-DOS). Use the information below to determine which format is best for you.

Use NTFS if…
...you will be using the drive only with Windows 2000, Windows XP or Windows Vista (performance will generally be greater when compared to FAT 32). This file system is compatible in read only mode with Mac OS X 10.3 and higher. See technical note at left for information on the 2TB volume size limitation under Windows XP 32-bit and Windows 2000.

Use FAT 32 (MS-DOS) if…
...you will be using your drive with both Windows and Mac OS X 10.3 or sharing the drive between Windows 2000 and Windows XP or Windows Vista. Maximum single file size is 4GB.

2TB limit on 32bits Windows systems

Windows XP 32-bit and Windows 2000 do not support volumes greater than 2TB. Windows XP x64, Windows Server 2003 SP1, and Windows Vista Enterprise/Ultimate (32- and 64-bit versions) do, but in order to create volumes bigger than 2TB from these operating systems, you must convert the disk to GPT file system.

FAT 32
FAT is an acronym for File Allocation Table, which dates back to the beginnings of DOS programming. Originally, FAT was only 16 bits, but after the second release of Windows 95 it was upgraded to 32 bits, hence the name FAT 32. In theory, FAT 32 volume sizes can range from less than 1MB all the way to 2TB. It is the native file system of Windows 98 and Windows Me, and is supported by Windows 2000, Windows XP and Windows Vista. When FAT 32 is used with Windows 2000, Windows XP and Windows Vista though, volume size is limited to 32GB (by the Windows partition utility, i.e. Disk Manager), and the individual file size is limited to 4GB.

NTFS
This acronym stands for New Technology Filing System, and it is the native file system for Windows NT, Windows 2000, Windows XP and Windows Vista. NTFS offers several features that are not available with FAT 32; i.e. file compression, encryption, permissions, and auditing, as well as the ability to mirror drives and RAID 5 capabilities. The minimum supported volume size for NTFS is 10MB, with a maximum of 2TB when initialized in MBR format or without a limit when initialized in GPT format, with no limit to file size. Volumes created in NTFS can only be directly accessed (not through shares) by Windows NT, Windows 2000, Windows XP and Windows Vista without resorting to help from third-party products.

Big O notation ...

n mathematics, computer science, and related fields, big O notation describes the limiting behavior of a function when the argument tends towards a particular value or infinity, usually in terms of simpler functions. Big O notation allows its users to simplify functions in order to concentrate on their growth rates: different functions with the same growth rate may be represented using the same O notation.

Returning Backspace as previous page button in Firefox @ Linux

Are you sick of pressing the back button at Firefox in Linux ? well, me too. So if you want to go back to the previous page by just pressing Backspace, then you gotto do some digging ;-)

The feature was removed to fix a bug. The bug that was caused by fixing the previous bug, which is that the backspace does not behave like it should has been fixed too (Thank heavens!)

But then, until the bug fix propagates to a Firefox build available on Ubuntu, one has to resort to a little scratching to fix the matter. Here’s how you resurrect the backspace button in Firefox 2.0 (worked for 3.o.10 today):

Type “about:config” in the address bar of Firefox and press Enter.
`Filter` for ‘browser.backspace_action’ and change its value to 0 (zero)
