MDTest 1.0
I'm announcing today a new testsuite application for Markdown called
MDTest. I've been using it as a replacement for John's Markdown Test
for some time now I think it's ready for release.
First, I want to say Markdown Test has been very useful in developing
PHP Markdown. The testsuite covers many cases, however I still found
the need to add other tests for PHP Markdown, to

MDTest 1.1
It has been a few months since the initial release of MDTest. I
haven't changed the testsuites much since then, but I've made a few
noticeable improvement to the test processor itself.
You can download MDTest here:
<http://michelf.com/docs/projets/mdtest-1.1.zip>
MDTest is also available now from the Git repository mirror at
<http://git.michelf.com/mdtest>.

CIFS client mounts meta ops 30 times slow than server
Hi Samba users,
We would like to use samba for re-exporting our other distributed file
system (BeeGFS). However, we found that the meta data operations are very
slow (dir stat, removal etc.). On SMB client the performance is more than
30x slow than on the SMB server. We would expect some slowness but this is
too big a drop.
This is the result on CIFS client

my scala markdown implementation
Hi,
I have written my own implementation of markdown in Scala. I only later
realized there is already one
( <http://tristanhunt.com/projects/knockoff/> ), but I put quite some
work into mine and I think it is never bad to have alternatives, so I
wanted to release it anyway. I want to use the same BSD License as the
original markdown, but before I put it out into the wild I wanted to ask

Understanding lustre setup ..
Hello,
I have been reading
http://wiki.lustre.org/images/1/1b/Hadoop_wp_v0.4.2.pdf for setting up
Hadoop over lustre.
Generally in hadoop setup, we have 1 Namenode and various number of datanodes.
If I want to setup the same keeping Lustre as backend, in the document
it is mentioned that:

Xyratex disk units
I am wondering if any one knows of a way to manage Xyratex disk shelves from CentOS (in particular CentOS 4).
More details:

Multicore computation in Windows network: How to set up Rmpi
R-users,
My question is related to earlier posts about benefits of quadcore over
dualcore computers; I am trying to setup a cluster of windows xp
computers so that eventually I could make use of 10-20 cpu:s, but for
learning how to do this, I am playing around with two laptops.
I thought that the package snow would come handy in this situation, but
to use snow, I would probably need to install

What is the most recent offical test suite ?
I just recently became aware of MarkdownTest_1.0.3 (which discount
fails, due to the behavior of code blocks changing from "leave
whitespace alone except on the first line" to "leave whitespace alone",
and the addition of a new kind of magic link that doesn't seem to be
documented); is this the most recent version of the test suite, or is
there a newer one out there?
