Hello Everyone!
Welcome to the January 17th, 2007 edition of Linux Journal Weekly News
Notes. On this week's eclectic menu you'll find Doc Searls wrapping up his
findings and musings on the CES show, as well as Jon Watson's guide to the
Win4Lin VDS. We also have a plea from Dave Phillips for all of us to better
support the amazing Linux audio projects out there.
Further on down you'll read about our Dot Org of the Week, X.org, followed
by Paddy Sreenvasan's tech tip on recovering a MySQL Table with Zmanda
Recovery Manager.
Use it to the max!

Doc talks about his first day at CES last week, including conversations with
Garmin, Netgear and Cambridge Consultants about the Linux inside of their
devices.
Break the Hardware Upgrade Cycle with Win4Lin Windows Virtual Desktop Server
by Jon Watson
http://www.linuxjournal.com/article/9358
Jon shows you how to migrate to the Win4Lin virtual desktop server, which
virtualizes Windows to Linux clients, and break the hardware upgrade cycle.
The Mobile Revolution Gets Personal by Doc Searls
http://www.linuxjournal.com/node/1000165
Although Doc was at CES when Steve Jobs announced the iPhone (at Macworld),
the announcement upstaged everything at CES and ignited a flurry of ideas
for him.
New E-Newsletter: Off the Shelf
http://www.linuxjournal.com/ots-newsletter
On Jan 19th we will inaugurate Off the Shelf, our newest e-newsletter here
at Linux Journal. This twice-monthly newsletter will keep you on the
cutting edge of developments on the Linux and Open Source products and
projects that our editors find new, note-worthy, time-saving, great deals or
just plain cool. Click on the above link to sign up!
All They Need Is Funds: A Call For Community Support by Dave Phillips
http://www.linuxjournal.com/node/1000166
Some of the best projects in Linux audio, Ardour and Hydrogen, are in need
of greater support from the community in order to insure their viability.
Dave expounds on what is needed from us to make it happen.
THE BRAIN TRUST: READERS SHARE THEIR EXPERTISE
This submission comes from Rappin' Billy in Washington, USA:
Once again, I attack that nasty interface device, the screen.
If you use a frame buffer on your console, you can use the "fbset" command
to change its resolution and to define X.org settings required for those.
To see what your frame buffer is doing right now:
fbset -s
To set the frame buffer to 1024x768 with 24 bpp, try this:
fbset -g 1024 768 1024 768 24
To see how you ought to define your X.org settings:
fbset -s -x
Note that in some distros you have to be logged in as root to run this
command and that more information can be found running the "man fbset"
command in the console.
Thanks to everyone for your forthcoming technical tips! Please send more of
them to share with our community of readers! My email is
jgray-at-linuxjournal.com. We'll send you a free t-shirt for your efforts.
Thanks!

Linux Distributions Compared by Michael Johnson (1996)

If the words "Yggdrasil Plug and Play Linux" make you weepy for the good old
days, this review is just what you need to take a trip down memory lane.
LINUX INCOGNITO: THERE'S LINUX INSIDE!
Our readers want to hear about your interesting experiences uncovering Linux
in an unexpected or innovative situation. Email them to me at
jgray-at-linuxjournal.com. If your contribution is selected for
publication, we'll send you a t-shirt!
DOT ORG OF THE WEEK
This submission comes from Kevin in Oregon, USA:
My nomination for the Dot Org of the Week is X.org. As it says on their
Website, "The X.Org Foundation [is the] global steward of the X Window
System and Standards" and "X11R7.1 supports Linux, Solaris, and BSD
systems. It includes important...server and driver features for embedded
systems, 64-bit platforms, enhanced operating system support, and
accelerated indirect GLX support."
Anyone who uses a modern Linux (or Unix-like) system in graphics mode, as
opposed to console mode, is probably using X.org. KDE and Gnome wouldn't
work without the X.org code. Nor would anyone's video card be able to
display graphics without proprietary drivers were it not for X.org. From
where I sit, typing away, my Linux system absolutely needs the kernel, GNU
utilities, and X.org support before anything else can run.
Do you know of an organization or person making a unique contribution to the
Linux community despite not getting paid for it? If so, we'd like to share
information about them with our readers. Send your recommendation, along
with why the organization/people are worthy of recognition, to
jgray-at-linuxjournal.com.
TECH TIP: Recover a MySQL Table with Zmanda Recovery Manager
If somebody accidentally drops a critical table in MySQL, the application no
longer works. The solution to this problem is to utilize the Zmanda
Recovery Manager.
You are a MySQL database administrator. You take regular backups of your
MySQL database. Somebody drops a table critical to the MySQL application
(for example, the "accounts" table in a SugarCRM application). The MySQL
application no longer works. How can you recover from the situation?
The answer is MySQL binary logs. Binary logs track all updates to the
database with minimal impact on database performance. MySQL binary logs
have to be enabled on the server. You can use the mysqlbinlog MySQL command
to recover from the binary logs.
A better and more comprehensive solution is to use the Zmanda Recovery
Manager (ZRM) for MySQL (MySQL backup and recovery manager). The mysql-zrm
tool allows users to browse the binary logs and selectively restore the
database from incremental backups:
# mysql-zrm --action parse-binlogs --source-directory=/var/lib/mysql
/sugarcrm/20060915101613
Log filename | Log Position | Timestamp | Event Type | Event
/var/lib/mysql/my-bin.000015 | 11013 | 06-09-12 06:20:03 | Xid = 4413 | COMMIT;
/var/lib/mysql/my-bin.000015 | 11159 | 06-09-12 06:20:03 | Query | DROP TABLE IF EXISTS `accounts`;
Here we're doing selective recovery for incremental backups without the DROP
customer table from the SugarCRM database. Do two selective restore
commands to restore from the incremental backup done on Sept 15, 2006,
without executing the database event DROP TABLE at log position 11159:
# mysql-zrm --action restore --backup-set sugarcrm \
--source-directory=/var/lib/mysql/ sugarcrm/20060915101613/ \
--stop-position 11014
# mysql-zrm --action restore --backup-set sugarcrm \
--source-directory=/var/lib/mysql/ sugarcrm/20060915101613/ \
--start-position 11160
See the Zmanda Recovery Manager for MySQL for more information:
