Running two R instances at the same time
...meaning that the two R *interpreter*
instances are talking to the same backend that's capable of processing
only one thing at a time?
Technical details: OS was Ubuntu 9.04 running on a Core2Dou E7300, and
the R version used was the default one from the Ubuntu repository.
Please see http://www.perlmonks.org/?node_id=792460 for an extended

actual code.

Alternatively, you can use a container. See for example:

Extract vowels and consonants using Ruby Regex
...mb
However, the regex does not accommodate the conditional treatment of
''y'' as a vowel *if there is no other vowel before or after it.* If
properly implemented, the previous examples would return: ayaaiea
(vowels) and mrhdlttllmb (consonants).
According to this post (http://www.perlmonks.org/?node_id=592867),
this could be accommodated in Perl using "zero-width negative-look-
behind" and "zero-width negative-look-ahead" assertions as follows:
my @vowels = ( /[aeiou]|(?<![aeiou])y(?![aeiou])/gi );
Where, the "(?<!...)" is a "zero-width neg...

Is Samba over an IPSec tunnel possible?
...unning on Sparc Solaris 2.6
The VPN tunnel is between a OpenBSD 2.7 server and a Netopia R9100
router. The tunnel is negotiated using IKE. The server running Samba
receives NetBIOS packets, I can see them using tcpdump. I have
formatted a capture and placed it on display at
http://grinder.perlmonk.org/tcpdump.html
I can see the differences between a successful connection and this
connection, but I don't understand enough to work out the reason
that it is failing. The router has a number of parameters that can
be used to tweak NetBIOS settings, but after having fiddled with a
few I haven...

XML to text
Is there anything offered in Centos that might convert an XML file to a
plain text file?
My hopes are that it is flexible enough to make the following type of line:
<title>Guide</title>
into something like:
title: Guide
along with all the other fields. It'd be nice if it could handle
multiple lines inside a single tag line as well.

NIS as user authentication
Hi all,
I believe that I have asked this in one form or another, but I did
not see an answer. ( it could be that I missed it ) do please forgive me
if I did, but could I ask you all to humor me for a moment.
Is there any way to get Samba to use YP ( NIS ) as the basis for
user authentication? If not at this time ( as I have not been able to

Very small scores for search results
Hi Everyone,
I''m using Ferret 0.10.11 with acts_as_ferret from SVN (same results with
0.10.10 and 0.10.9 though).
I''m running into an odd problem where the scores of my top-ranking
search results are ridiculously small - even when the query is one that
should match at least one document with a decent score.
To give an example, I have just the names of 5 businesses indexed

[PATCH] customize: Test that the --root-password parameter works.
This is the second half of the patch series posted yesterday (see:
"[PATCH 0/2] builder: Add test that a serial console is set up for
guest templates we supply.").
This checks that our code to change passwords works on real guests.
It creates a real guest using virt-builder with the --root-password
option, then boots it up and tries to log in with the root password.

question on downsampling
Hi,
Maybe a bit off topic for this list, bt anyway.
I have received several feature requests for DarkIce to support
downsampling of the audio input before passing it to lame or ogg vorbis.
For example the audio read from the soundcard would be 44.1kHz, and lame
would get it at 22.05kHz.
I figure two ways of doing this:
1. For lame, one can specify the input and the desired mp3 sampling

[hivex] Segfault for an integer value to node_set_value
Hi,
When an integer argument is passed as value, node_set_value
segfaults. Reproducer is at the end of this message
The backtrace points at hivex-py.c, function get_value. While obj
is non-NULL, `bytes = PyUnicode_AsUTF8String (obj);` returns NULL.
Kind regards,

[hivex] [PATCH 0/6] Python fixes for node_set_value
Hi,
This patch series is based on a prior patch[1], splitting off changes as
requested and incorporating feedback from Richard Jones. It introduces type
validation to avoid segmentation faults (instead, it reports an exception) and
fixes handling of the bytes type in Python 3.
Major changes since that series:
- Drop newly introduced support for integer types for DWORD/QWORDS
- Reject Unicode

[PATCH 0/23] factor and const-correctness
This started as a simple warning-elimination change.
I'll get back to that series shortly ;-)
It turned into a factorization and constification exercise
during which I got a taste of ocaml. Thanks to Rich Jones
for help with a few snippets in generator.ml.
The overall result is that many previously-manually-maintained
bits from daemon/*.c functions are now hoisted into the automatically-

[PATCH v2] Add progress bars
This is an updated and extended version of the original patch:
https://www.redhat.com/archives/libguestfs/2010-August/msg00163.html
This adds OCaml and Perl bindings (both tested), support for
progress bars in virt-resize, and adds progress notifications
to a number of the simpler commands.
Still to do is to add progress messages to more commands. There
are still a few commands which would be

multiple smb daemons
Is it possible to bind multiple smb daemons to different NICs on the same machine ? Here is my dilemma:
I had about three print servers with different names on NT.
There were on average, 120 print share on each. I would like to try to merge all of those printer share into 1 single machine. Aliases on NT do not seem to work fo r printer shares (file shares work fine). My idea was to replace all
