Windows Windows testers will get a new beta version of Windows Vista, dubbed the December Community Technology Preview beta build, just before next week's holidays, according to tester scuttlebutt. New to the December release, testers say, will be a number of features and user-interface tweaks. a new defrag module; tight integration of Windows Defender (formerly known as Windows AntiSpyware); and a functional parental-controls filter are all rumored to be in the December Vista build.

NTFS exist in five version, and none of then are really journaled file systems, since they can whote charges on the journal, but cannot revert then in case of failure, because of that you yet need to sleep in the front of pc waiting scandisk check the entire disk in case of a power outrage for example.

On linux, you just sleep in the front of fsck for maintence reasons. In case who the system are not properly shutdown, no need of fsck ate all, the system can boot at full speed, reverting the changes on journal automagically.

And no modern linux file system needs to be defragmented. Since ext2, data are ordered on the fly on disk. Rates of fragmentation are very small always. Rarely goes above 6%, just pass fsck on a linux file system, they report the level of fragmentation, you will notice sometimes they go 6%, and after some file operations due normal usage of pc, they go below 3% without no apparent reason.
And just to remenber you: ext/ext3 are just 2 of file systems who linux can use by default: you have also reiserfs, jfs and xfs.

Patently false. All of them are journalled, and of course can revert in case of failure. Your article's writer is misinformed. Try using more than just your first hit from Google.

(Read the sections on NTFS File System Recoverability and Recovering NTFS File Structures if you want to learn how this actually works. The 2003 Technical Reference should always be your first stop for understanding MS technologies, not backupbook.com, whatever that is). My original fact remains - it was 10 years after NTFS that Ext3 came around and Linux finally had journalling.

I have no idea what this means. There is no such thing as ScanDisk in NT-Vista or in NTFS. You're thinking of Win95/98.

I still don't understand why I find these links for defragging Ext2, with useful utilities and methods to do so. I get it that ExtX has built in real-time defragmentation - so does NTFS. It just sounds like ExtX is better - but not enough that people aren't writing apps to do it anyways.

It's quite amusing to see linux fanboys shooting themselves in the foot with proofs of not using any NT kernel based Windows such as XP/W2K.

Speaking of filesystems, how many linux filesystems have support for transactions on API-based level (ie complete ACID semantics), like NTFS 6 on Vista has?

Errr..none.

How many of them have self-healing capabilites like NTFS 6 on Vista has (no more fsck, no more autochk.exe/chkdsk.exe)?

Errr...none.

How many linux filesystems have object-relational mappings such as WinFS, which is currently in beta 1 and will be available as redistributable shortly after Vista RTMs?

Errr...none

It took ext* 10 years to get something as "complex" as journalling, it will probably fully supprot ACID and self-healing somewhere in 2020 ;)

No.. the technical article posted are right, some people do not consider NTFS a pure journal file system because it do not suport block jornaling, but only metadata journaling for performance reasons.

You are confusing fragmentation resistence with on the fly defrag. ExtX do not execute a defrag process on background using CPU idle time, it in fact write the data on disk in a organizated manner. Now.. who method are better, serious, i don't know.
