&lt;rob0&gt; Yes it is the reiserfs site.
&lt;echelon_&gt; that's what they get for using russian dns servers
&lt;Cherife&gt; lol
&lt;rob0&gt; Probably can find it in google cache or wayback machine.
&lt;sallygal&gt; echelon_, you just kill me
&lt;sallygal&gt; :)
&lt;rob0&gt; It's nominally a Russian-based company, only the owner is in jail in USA.
&lt;echelon_&gt; now what did he do that was so bad?
&lt;sallygal&gt; killed her
&lt;rob0&gt; Accused of murder, you hadn't heard?
&lt;rob0&gt; His estranged wife is missing
&lt;echelon_&gt; <strong>nice.. i'm using the fs of a murderer</strong> :D

			<content:encoded><![CDATA[<p>Yesterday, Slackware -current repo got a big update &#8212; mainly kernel related stuff. Besides, Pat moved ntfsprogs tgz from /extra to ap/, which now includes full read-write support when the NTFS filesystem is mounted with ntfsmount or -t fuse.ntfs. This feature requires FUSE, which is added by Pat too.<br />
Now we Slackers won&#8217;t need to do much superfluous things ourselves to implementation full read-write support feature. I&#8217;m just a bit lazy, sometimes :-)</p>
<p>An simple intro from the <a href="http://fuse.sourceforge.net/" target="_blank" title="FUSE: Filesystem in Userspace">FUSE website</a>:</p>
<pre>
With FUSE it is possible to implement a fully functional filesystem in a userspace program.  Features include:

    * Simple library API
    * Simple installation (no need to patch or recompile the kernel)
    * Secure implementation
    * Userspace - kernel interface is very efficient
    * Usable by non privileged users
    * Runs on Linux kernels 2.4.X and 2.6.X
    * Has proven very stable over time
</pre>
<p>The following figure shows the path of a filesystem call:<br />
<a href='http://dotimes.com/iscale/wp-content/uploads/2008/03/fuse_structure.png' title='fuse structure'><img src='http://dotimes.com/iscale/wp-content/uploads/2008/03/fuse_structure.png' alt='fuse structure' /></a></p>
<p>Operating Systems FUSE Supportes are Linux-2.4.X, Linux-2.6.X, FreeBSD, NetBSD, Mac OS X, Windows, OpenSolaris, GNU/Hurd. Check <a href="http://fuse.sourceforge.net/wiki/index.php/OperatingSystems" target="_blank" title="Detailed Operating Systems FUSE Supports">this link</a> for detail.</p>
<p>There are various types of Filesystems based on FUSE, like:</p>
<pre>
# ArchiveFileSystems - accessing files inside archives (tar, cpio, zip, etc.)
# CompressedFileSystems - accessing files in a compressed image (gz, zlib, LiveCDs, etc.)
# DatabaseFileSystems - storing files in a relational database (MySQL, BerkeleyDB, etc.) \
    or ones allowing searching using tags or SQL queries
# EncryptedFileSystems - storing files in a more secure way by using a secret key
# MediaFileSystems - storing files on media devices such as cameras and music players \
    or accessing and categorizing media files
# HardwareFileSystems - provide access to weird hardware
# MonitoringFileSystems - provide notification when a file changes
# NetworkFileSystems - storing files on remote computers, including file servers and web sites
# NonNativeFileSystems - traditional disk-based file systems that aren't standard on \
    Linux (NTFS, ZFS, etc.)
# UnionFileSystems - merging multiple file systems into a single tree
# VersioningFileSystems - file systems that remember old versions of files and ones which \
    provide access to version control systems
</pre>
