LinuxCertified.com offers the weekend system administration
bootcamp for busy IT professionals
- - All attendees get a free Linux laptop!

LinuxCertified.com, a leading provider of Linux training, will
offer its next weekend system administration bootcamp on April
7 - 8, 2001 in San Francisco bay area (south bay). This
workshop is designed for busy information technology profession-
als and is designed to cover the most important Linux administra-
tion areas.
In addition to carefully designed lecture material delivered by
experienced Linux professionals, there is a heavy emphasis on
hands-on learning. The training starts two weeks before the actu-
al class, with access to an online Linux server, where students
complete few challenging pre-class activities. Attendees get a
powerful Linux laptop on their arrival, along with other class
materials. They load Linux on their laptop during the class, and
use it for all the class activities and assignments. At the end
of the class they take this laptop with them to further enhance
their Linux expertise. Absolute beginners with no UNIX experience
can first come to the popular "Linux for Beginners" class and
subsequently join the system administration bootcamp.
Rapid growth of Linux into corporate and government IT environ-
ments is fueling the need for Linux certified professionals. CIOs
and managers are eager to have Linux experts in their organiza-
tions. A certification provides a tangible mechanism for their
hiring evaluation, as well as a means to market the prowess of
organizations.
"As an independent IT consultant I am always on my toes to learn
new technologies, without much free time to devote to classes.
The LinuxCertified.com bootcamp was a perfect way for me to jump-
start my Linux knowledge. I can now use Linux as a valuable
tool in my career," said Taylor Cottam, an independent consultant
who joined one of the LinuxCertified.com weekend bootcamps.
This weekend bootcamp is specially designed to prepare the at-
tendees for the objectives of Level 1 certification exams offered
by Linux Professional Institute (LPI). The workshop also meets
the objectives of the Red Hat Certified Engineer (RHCE) exam and
Sair Linux & GNU certification (LCA).
Our attendees build a strong sense of community with our instructors,
fellow students, and our network of recruiters and companies
looking for Linux consultants.
About LinuxCertified.com
The mission of LinuxCertified.com is to bring Linux to mainstream
IT usage. We firmly believe that Linux has an enormous potential,
once it crosses over from the early adopters to the more mainstream
users. Our goal is to help this transition by providing:
- - Linux trained and certified professionals
- - Linux certified products that cater to mainstream users rather
than early adopters.

Subject: Mahogany 0.62 mail and news client
Date: Sun, 25 Mar 2001 00:02:54 GMT
=====BEGIN PGP SIGNED MESSAGE=====
A new release of the `Mahogany' e-Mail and News client has been made.
=====================================================================
Source and binaries for a variety of Linux and Unix systems as well
as binaries for Win32 are available at
http://sourceforge.net/project/showfiles.php?group_id=3100
You can also get to the download page starting from
http://mahogany.sourceforge.net/
NB: My sincere excuses to all people who have written me asking for
Win32 binaries and to whom I couldn't reply because there were
so many of them. For personal reasons I couldn't make the Win32
version as soon as I hoped to.
In this message:
1. Announcing Mahogany Version 0.62
2. Changes Against the Previous Release
Announcing Mahogany Version 0.62
=====================================================================
Mahogany is an OpenSource(TM) cross-platform mail and news client. It
is available for X11/Unix and MS Windows platforms, supporting a wide
range of protocols and standards, including POP3, IMAP4 and full MIME
support as well as secure communications via SSL. Mahogany can be
extended far beyond its original functionality using its built-in
Python interpreter and/or its loadable modules (plug-ins).
Mahogany's wealth of features and ease of use make it one of the most
powerful clients available, providing a consistent and intuitive
interface across all supported platforms and an ideal GUI email client
for advanced and novice users alike.
Mahogany includes an extendable address book system supporting
hierarchical organisation of entries, group aliases, searching the
database and easy editing, with support for other programs' address
database formats. Currently Mahogany's native format, (X)Emacs' BBDB
address books and PalmOS address books are supported. LDAP support is
planned for future versions.
Mahogany is written using the OpenSource wxWindows application
framework for GUI C++ applications, building on the GTK+ toolkit on
Unix and native Win32 API under Windows and imap-2000 (c-client)
library developed by University of Washington for mail folder access.
Mahogany is constantly being tested on a variety of Linux systems,
Solaris-sparc and MS Windows. It should compile and work on any modern
Unix platform.
Changes Since Release 0.60
=====================================================================
Key changes are:
- fixes to several fatal crashes with IMAP servers
- significant speed up of some operations (although more
optimizations are to come)
- availability of Win32 version
- Mahogany is now dual licensed under its Artistic License and GPL
New features:
- support for marking message as flagged/important
- "Extract all addresses from message" command
- possibility to import all MBOX folders under the given directory
- possibility to set a hard limit for number of messages retrieved
from a (remote) folder
Improvements:
- folders in the tree can now be rearranged, system folders are at
top by default
- messages can now be sorted by status and by size as well
- title and status bar of folder view are customizable strings which
can include information about the number of new/unread/flagged
messages
- show filtering progress in the status bar
- filters dialog is now more convenient to use
- new mail reporting was made less intrusive
Bug fixes:
- reading newsgroups doesn't crash the program immediately
- parsing of complex MIME structures fixed
- language autodetection fixed
- fixed crash when viewing messages with wrong date
Please see the CHANGES file in the distribution for an even more
detailed list of changes.
Future Plans
=====================================================================
Next, we hope to tackle the following:
- improving the message editor (work in progress)
- full HTML message editing/displaying (almost complete)
- multi-threading to allow network operations to happen in
background
- PGP/GPG support
- LDAP support
Please direct any queries to mahogany-developers@lists.sourceforge.net
and don't hesitate to contact us if you would like to participate in
Mahogany development!
Known bugs:
- -----------
*** Please note that Mahogany/UNIX is officially in beta state while
*** Mahogany/Win32 is still considered to be in alpha stage (although
*** we use both versions on the daily basis).
There are always some, listed on our bugtracker at
http://mahogany.sourceforge.net/bugz/ and we are working on them.
Hoping you will find Mahogany useful,
M dev-team

Subject: xmlppm 0.95.1 - an XML-specific compressor
Date: Sat, 24 Mar 2001 23:58:59 GMT
=====BEGIN PGP SIGNED MESSAGE=====
xmlppm 0.95.1 -- release announcement
- -------------------------------------
What is xmlppm?
- ---------------
Xmlppm is an XML-specific compressor based on the state-of-the-art PPM
text compression algorithm. Although slow, xmlppm can compress XML
files from 5% to 20% better than bzip2 (which typically does better
than gzip). Xmlppm also compresses better than the "plain" version of
XMILL, another XML-specific compressor (although it may be possible to
do better with XMILL by fine-tuning its command-line options).
Xmlppm is currently in an alpha state; I feel that it is "close to" a
stable state (hence the rather high release number), but could be
wrong. Bug reports are welcome.
The source of xmlppm is available online at Sourceforge under the terms
of the GPL. Xmlppm still needs improvement and testing before it will
be reliable and fast enough for general use. I am a graduate student
and this is not my area of specialization, so I will probably not be
able to devote a lot of time to this project. Thus, development
assistance is also welcome.
How does it work?
- -----------------
Xmlppm uses expat to parse the input document into a sequence of SAX
event handler calls. Each event handler sends information that
encodes the event to one of four text compressors (using the PPM text
compression algorithm), one each for a symbol table, element tag
stream, attribute tag stream, and plain text stream. Separating the
encoded event information this way avoids the problem of "dilution"
where a single model tries to adapt to multiple different sources mixed
together. On the other hand, breaking the data up can harm compression
by breaking patterns that cross over from the element to attributes or
character streams. To make up for this, xmlppm tells the models about
symbols from other streams that are inferrable from context and so
don't need to be encoded or decoded.
This is a rather terse description; see the xmlppm web page,
http://xmlppm.sourceforge.net/
for more information.
Getting xmlppm
- --------------
The source release and CVS tree are at
http://sourceforge.net/projects/xmlppm/
To compile xmlppm, you will also need the expat XML parsing library
installed. If there is demand, I would be happy to make a
statically-linked binary distribution for my platform (i386 Linux).
Xmlppm is known to work on i386 Linux, and I would guess that it works
on other Unix platforms as well, but I have not tested it. At this
point, xmlppm is known not to work under Windows due to some
non-portability-conscious coding on my part. Mea culpa.
Thanks to Bill Teahan and Alistair Moffat for allowing me to make use
of their arithmetic coding and PPM implementations and to place them
under the GPL as part of xmlppm. Thanks also to the expat developers.

ease-of-use: it requires no site-specific configuration, regardless of
the users and software present on the system.
Although a good number of features and fixes remain to be
implemented, LOMAC is presently functional enough to thwart script
kiddies, and is sufficiently stable for everyday use on servers and
workstations. The v1.0.5 release includes several improvements:
o remote administration is now allowed via ssh only,
o both manual and automatic NFS mounts now operate properly,
o log messages now contain more precise information, and
o support and documentation is now present for Debian users.
LOMAC is Free software, available under the GNU GPL. The distribution
and supporting documentation is available via LOMAC's Freshmeat page:
