=================================================================
Good day, Readers. Welcome to the potentially final Linux
newsletter of 2004. As 2004 winds down, the U.S. often shuts
down for a week or so. That won't prevent us from continuing
to cover the latest and best in open source usage, administration,
development, and advocacy, though. We'll just do it a bit more
slowly for a while.
Here are the latest articles as seen on ONLamp.com this week.
Noel Davis' security alerts identify potential remote exploits
in Sun's and Blackdown's J2SE distributions, wget, OpenSSH,
AbiWord, Blogtorrent, rssh and scponly, and kfax. Please check
with your vendor for the status of your packages and the
availability of patches and updates:
<http://www.linuxdevcenter.com/pub/a/linux/2004/12/17/security_alerts.html>
Application developers know that change is inevitable--if not
in the specifications, then in the operating environment.
Sometimes you really have to know if files or directories have
changed. If you've ever coded a select() loop trying to watch
for changes, you know how difficult it is to do correctly.
Ethan McCallum knows a better way: SGI's FAM. "The Watchful
Eye of FAM" explains how to use this library to monitor file
and directory changes:
<http://www.linuxdevcenter.com/pub/a/linux/2004/12/16/fam.html>
In the past couple of years, audio on Linux has really
bloomed--more and more drivers, an advanced sound system, and
great frameworks for processing. Now higher-level tools have
caught up. For example, Rosegarden is a free software sequencer
and scoring package, with version 1.0 almost ready to release.
Howard Wen profiles the project and interviews its developers:
<http://www.linuxdevcenter.com/pub/a/linux/2004/12/16/rosegarden.html>
Is there any sweeter word to serious IT managers and vendors
than "cluster"? ("Free" apparently doesn't work on them.)
Having introduced the Slony project, which brings replication
to PostgreSQL, Elein Mustain returns with a tutorial on installing
and configuring Slony. This is also a nice way to migrate from
one version to another.
<http://www.onlamp.com/pub/a/onlamp/2004/12/16/slony_install.html>
In this week's weblogs, Uche Ogbuji ponders nested scopes in
Python:
<http://weblogs.oreilly.com/pub/wlg/6063>
Todd Ogasawara lists several recent Python releases:
<http://weblogs.oreilly.com/pub/wlg/6069>
David Battino mentions a computer music discussion at the
Computer History Museum:

Chandu Thota finds addresses from postal codes with MapPoint:
<http://weblogs.oreilly.com/pub/wlg/6072>
Jason Deraleau loves his disk images:
<http://weblogs.oreilly.com/pub/wlg/6074>
Simon St. Laurent thinks that some promises of web services
arrived years before web services themselves did:
<http://weblogs.oreilly.com/pub/wlg/6078>
Jacek Artymiak dismisses the idea of graphical installers for
the BSDs:
<http://weblogs.oreilly.com/pub/wlg/6080>
Glenn Bisignani submits a Perl Success Story:
<http://weblogs.oreilly.com/pub/wlg/6084>
Brian Sawyer recommends reading about the relationship between
editors and authors:
<http://weblogs.oreilly.com/pub/wlg/6083>
Derek Sivers ponders test-driven development:
<http://weblogs.oreilly.com/pub/wlg/6090>
brian d foy suggests more uses for RSS:
<http://weblogs.oreilly.com/pub/wlg/6095>
Erica Sadun challenges hackers to help her throw away a trash
can:
<http://weblogs.oreilly.com/pub/wlg/6098>
This week's Open Source Project of the Week is YourSQL, a MySQL
administration client for Mac OS X:
<http://osdir.com/Downloads+index-req-viewdownloaddetails-lid-224-ttitle-YourSQL.phtml>
That's all for this week. Have an appropriate end of the year,
if your calendar thinks this is the end of the year.
(Internationalization and Localization are still difficult
problems.) Tune in next week for some insightful words about
freedom, innovation, and pragmatism in software.
Until the same time next week,
chromatic

ONLamp.com and Linux Devcenter Top Five Articles Last Week
1. Linux Music Blossoms with Rosegarden
No kidding: many software geeks are also music geeks. It should
be no surprise that free software music programs have started
to rival their commercial counterparts. Howard Wen walks through
Rosegarden, a Linux-based music sequencer and scoring package.
<http://www.linuxdevcenter.com/pub/a/linux/2004/12/16/rosegarden.html>
***
2. Building and Configuring Slony
Slony is the intended replication project for the PostgreSQL
database. Now that you know what it is, how do you use it? A.
Elein Mustain demonstrates how to build, install, and configure
Slony.
<http://www.onlamp.com/pub/a/onlamp/2004/12/16/slony_install.html>
***
3. Implementing Hardware RAID on FreeBSD
Want better performance, higher reliability, and better recovery
possibilities from your disks? Try RAID. Dan Langille recently
made the switch to hardware RAID on his FreeBSD box; here's
how he did it.
<http://www.onlamp.com/pub/a//bsd/2004/12/09/raid.html>
***
4. Adding Permissions Using SELinux
As an SELinux administrator, one of the most frequent SELinux
policy customizations you're likely to perform is adding
permissions to coax the security engine into accepting an
operation. In today's excerpt from SELinux, author Bill McCarty
considers an actual situation based on Fedora Core 2's SELinux
implementation and shows how it's resolved.
<http://www.linuxdevcenter.com/pub/a/linux/excerpt/selnx_1/>
***
5. Automating PostgreSQL Tasks
Databases aren't just create-once, ignore forever sinkholes
for data. You'll likely spend time maintaining them, if not
generating reports. Save your tender wrists and automate some
of those routine tasks. Manni Wood demonstrates how to combine
Perl, the shell, and the psql command-line utility to do
repetitive jobs for you.
