This is the Gentoo Weekly Newsletter for the week of 20 March 2006.

Gentoo x86 arch testers wanted
------------------------------
 
The x86 team has adopted the Arch Tester program and is looking for some
ambitious members of the community to join the team and help out. If you
would like to give back to Gentoo, but don't know how, then this may be a
good way for you to start. You would be helping by testing applications to
be marked stable and assisting in general x86-specific bugs. Please take a
look at the x86 AT documentation[1], and if you have questions about
anything, please either email Homer Parker[2] or Mark Loeser[3].

New Athlon X2 for Gentoo developers
-----------------------------------
 
As part of Roger Williams University[4] and the School of Business'[5]
continuing expansion into undergraduate and graduate research, access to a
dual-core Athlon X2 is now being provided to faculty, staff and students
of RWU -- and to Gentoo developers! The new host -- baptized "pearl" --
will facilitate Gentoo's official support for dual-core AMD64 systems in
the future. Thanks to RWU for their generous support!

Countdown for Modular X
-----------------------
 
As reported in the GWN of 30 January[6], the X team is preparing to unmask
289 modular X packages. They will enter ~arch (testing) this week for most
architectures, be sure to read the migration guide[7] before upgrading to
modular X!

Gentoo girls wear, anyone?
 
A female Forums user, star.dancer[8], shows her disappointment in the
total absence of Gentoo merchandise for women. Maybe it's the time to add
women apparel and other schwag on the official Gentoo Store?

glibc 2.4 some more
 
Last week's GWN mentioned the ascension of glibc-2.4 into the Portage
tree. As the number of users that emerge it grows, problems are increasing
as well. Some users confess to have fallen into a real mess with
glibc-2.4, the libc.so.6 library and the nptl and nptlonly USE flags,
while others using prelink on their respective systems had to prelink
their whole system again:
 
 * glibc, libc.so.6, nptl, nptlonly = problems[11]
 * Upgrading to glibc requires nptlonly use flag[12]

Overlay for overlays?
 
Some users have been discussing alternatives for applications to find
their way into Portage. One idea is to publish the most popular overlays
on a website. What do you think?
 
 * maybe a better way to get programmes into portage[13]

Japan: OSC 2006 spring event report
-----------------------------------

Note: Cover art for the CD hand-outs at the OSC booth can be downloaded
from Tomoyuki Sakurai's webspace.
 
The media didn't last long: GentooJP had 150 CDs prepared as give-aways at
the Tokyo Open-Source Conference last weekend, but they were "sold out" by
the end of the first day. The Gentoo x86 and PPC boxes on display at the
booth showed the first official release of the Gentoo installer, and KDE.
Gentoo developers to visit or man the booth included Matsuu Takuto[14],
Shigehiro Idani[15], Jason Stubbs[16] and Mamoru Komachi[17], the latter
just back from Europe where he went to the FOSDEM meeting in Brussels.

Twelve attendants participated in the "Gentoo ebuild Howto" session, an
unexpectedly high turnout of people actually interested in writing and
submitting ebuilds themselves. There's hope for some of them to eventually
help with Gentoo development, especially in i18n and CJK.
 
The day ended as usual, with a nomikai (drinking bout) at an izakaya
(pub). The next meeting to be held in the Tokyo area is scheduled for
sometime in April, when Dutch Gentoo developer Andres Loeh[18] will be in
town for a conference. If you are available around that time, join
#gentoo-ja on irc.freenode.net or subscribe to the GentooJP mailing list

Distrowatch (13 March 2006)
---------------------------
 
Distrowatch has mentioned Kororaa[19] -- a Gentoo-based binary
distribution featuring a simplified installation process -- before, in
November 2005[20]. The GWN in turn featured the Kororaa project's latest
release of an Xgl LiveCD[21] just last week. Now the amazing 3D effects of
the Xgl display server as you manipulate windows on your desktop have
caught Ladislav Bodnar's attention too, who interviewed Chris Smart[22] in
his last edition. A similar interview and an article appeared in NewsForge
a day later[23].

==================
5. Tips and tricks
==================
 
Efficient file change notifications
-----------------------------------
 
Many applications rely on tracking filesystem changes internally, and
until recently, the most popular library providing functionality like this
was app-admin/fam. Packages which use FAM for file-monitoring include
GNOME, KDE, PHP, various file managers, various mail clients and servers,
and many more. FAM works by repeatedly polling directory contents and
looking to see if things have changed. This is inefficient, but it did the
job for a while.
 
More recently, ultra-efficient kernel-side support for monitoring file
changes was merged into Linux 2.6. This functionality, called inotify, is
on by default, and is probably already available on your system (assuming
you are relatively up-to-date). app-admin/gamin is a direct replacement
for FAM, even implementing an identical API. The biggest bonus about gamin
is that where available, gamin monitors the filesystem using inotify,
destroying the ugly overhead which FAM had.
 
Gamin will be the default for new Gentoo installs, but there is no
automatic migration for existing users at this time. It is recommended
that you make the switch manually:
 
+-------------------------------------------------------------------------+
| Code Listing 5.1:                                                       |
| Switching to gamin                                                      |
+-------------------------------------------------------------------------+
|                                                                         |
|# emerge -C app-admin/fam                                                |
|# emerge --oneshot app-admin/gamin                                       |
|It is not necessary to re-merge any software that is built on            |
|FAM, as gamin is literally a drop-in replacement.                        |
|                                                                         |
|                                                                         |
+-------------------------------------------------------------------------+
 
Note:  Gamin also supports plain old filesystem polling, and seems to do a
better job than FAM did. Even if you do not have an inotify-enabled
system, it is still recommended that you change.
 
Given that the overhead for monitoring filesystem events is now so low, it
is also suggested that you enable file-monitoring support for applications
which optionally support it. To do so, enable the "fam" USE flag:
 
+-------------------------------------------------------------------------+
| Code Listing 5.2:                                                       |
| Add 'fam' USE flag and rebuild world                                    |
+-------------------------------------------------------------------------+
|                                                                         |
|# nano -w /etc/make.conf                                                 |
|Add "fam" to your USE variable and save the file                         |
|# emerge --newuse world                                                  |
|                                                                         |
