--- Fedora 12 (Constantine) ---

---- The Fedora Project and IPv6 ----

The top news of the week was the Fedora Project and IPv6 by Fedora 
Infrastructure Lead and project coordinator Mike McGrath. Mike had 
announced [1] that as part of the constant effort toward supporting 
current and future standards, major segments of fedoraproject.org and 
the Fedora Project infrastructure now support IPv6. He also mentioned, 
"our self-hosted websites have already been converted, and we plan to 
include IPv6 GeoIP support in MirrorManager soon."

Mike extended special thanks to Matt Domsch from Dell and our friends at 
ibiblio.org for their invaluable assistance on behalf of the Fedora Project.


---- Licensing policy for apps developed by Fedora Infrastructure now in 
effect ----

Toshio Kuratomi on Development-Announcement announced,[1] "Over the past 
few months, Fedora Infrastructure has been discussing having a 
consistent set of licenses for applications and scripts we create for 
Fedora." On his specific details, he informed everyone about the the 
goals of doing this, the basics, the uses of GPLv2 or later.

"The one other thing for Infrastructure developers and System Admins to 
note in the Policy is the section on handling AGPLv3 applications. 
During the discussions about whether to use AGPLv3+ for our web 
applications we found and delimited many issues that need to be 
addressed when deploying AGPLv3+ licensed code. The aGPL portion of the 
policy is our first attempt at keeping us compliant with any code that 
is under this license.", highlighted by Toshio.

-- Planet Fedora --

In this section, we cover the highlights of Planet Fedora[1] - an 
aggregation of blogs from Fedora contributors worldwide.

Contributing Writer: Adam Batkin

--- General ---

It has been about four weeks since the last installment of Planet Fedora 
here, so we'll be presenting a mix of interesting topics covering that 
time period. Normal weekly coverage should resume next week.

Nicu Buceli expressed[1] concern about The Great Panda Debate. "Already 
Panda iz in ur computer, developing Fedora".

Máirín Duffy did a few sets of UI mockups for Fedora. The first 
mockup[2] was of a new look for the Fedora Spins site. The other[3] was 
for a new set of screens for handling advanced storage device 
configuration in Anaconda.

Colin Walters showed off[4] mockups of the new Gnome 3 shell, which 
radically changes the way that applications are launched and managed.

Andrew Overholt mentioned[5] that a new version of the Eclipse Linux 
Tools (0.3.0) has been released. Eye candy included.

Jef Spaleta analyzed[6][7] the productivity of Fedora packagers and the 
rate that the number of Fedora packages and Fedora packagers has changed 
over the last few releases.

Máirín Duffy looked at[8] the "Getting Fedora" survey results. Also, 
further discussion[9].

Mark J Cox examined[10] the security vulnerabilities affecting RHEL 
between release 5.3 and (the just-released) 5.4.

Tim Waugh described[11] how printing has improved and is more flexible 
in Fedora, now that PolicyKit has been integrated with CUPS.

Michael DeHaan presented[12] a vision for fedorahosted.org.

Luis Villa asked[13] if "there a state of the art for free software 
project bounties?"

Mathieu Bridon continued[14] developing a git-aware BASH prompt.

Mel Chua explained[15] "How the zikula-based test instance of FI was put 
up, part 1". (Zikula is the new CMS that is being deployed for a number 
of Fedora sites)

Nicu Buceli posted[16] photos from FLOSSCamp 2009.

Richard Hughes stumbled[17] upon an interesting bug in 
gnome-power-manager, where the screen will suddenly blank, even though 
the system is in active use.

Richard W.M. Jones answered[18] the question "How does mount load the 
right kernel module?"

Kamil Páral introduced[19] zsync, a tool that can efficiently 
synchronize binary files over a network. "It allows you to download a 
file from a remote server, where you have a copy of an older version of 
the file on your computer already. zsync downloads only the new parts of 
the file."

-- Marketing --

In this section, we cover the Fedora Marketing Project.


Contributing Writer: Chaitanya Mehandru

--- Marketing Meeting Log for 2009-09-01 ---

Meeting logs [1] and notes [2] for the 2009-09-01 Fedora Marketing 
Meeting were made available. All Marketing meetings and notes are open 
to the public. [3]

Lot of people turned up for this week's meeting and many topics were 
covered. Thanks for the interest shown!

--- Release deliverables ---

This bread and butter stuff covers feature profiles, talking points, 
release announcements -things that have to come out every cycle.The 
complete schedule is available[4].

For F12 talking points and feature profiles, Mel Chua pointed out the 
need for recruiting college marketing classes to sprint on 

Mel identified/updated the needs for the release cycle: release 
slogans,briefing ambassadors,Fedora Insight Status/Questions, 
Modules/Packaging Status("Zikula guruhood needed"), press kits, 
screenshots, F12 tour, Workflow, Skins/Design, "Increasing our 
Marketing-fu", marketing research, marketing plan to work with RH 
marketing folks, projects for newcomers, marketing classroom with Sean 
Daly and later in the pipeline will be: press kits, screenshots, F12 tour.

--- Briefing Ambassadors about F12 ---

Ambassador can help greatly in bringing out what is marketing doing. 
Ambassadors/Students/Newcomers interested in some real marketing stuff 
can add their questions to the queue[5].

Our search is on for ambassadors/students who would be interested in 
working on marketing deliverables.

--- Fedora Insight updates ---

Three words: "Workflow is settled". Thanks to Robyn Bergeron. The 
workflow will be posted soon [6].

Technical Zikula deployment is going very rapidly.

--- Marketing-fu++ ---

Please add your valuable comments on the marketing plan[7] before Mel 
goes ahead and discusses it with RedHat folks.

Sugar Labs's Sean Daly will be coming in for a Fedora Classroom session 
on Marketing for open source projects when he gets back from 
vacation(expecting him to be back by this week or the next)

--- Marketing Research ---

While fedora-centric style of research continues with its own 
importance, ideas & opinions were expressed on community-style research 
where the research benefits not only the fedora users but also those 
developing open-spurce projects in general. An open-source market 
research repository might also be started to help foster the whole 
community of OSS.

--- Fedora print magazine proposed ---

Linux Pro Magazine has proposed printing a special Fedora issue around 
the launch of F12. [8] We are trying to explore whether this might be a 
possibility, and if so, whether it's something that we as a community 
want to pursue. [9] Conversations on various team mailing lists are 
ongoing - please join the conversation for the topics you are interested 
in! [10]

--- Registration opens for Utah Open Source Conference ---

Registration is now open for Utah Open Source Conference 2009, to be 
held in Salt Lake City, Utah, from Oct. 8-10. This is the third year of 
this annual event, and Fedora is one of the sponsors.

Fedora will have a booth at the event and those in the area are urged to 
attend the event and are welcome to help out. For more information on 
staffing the booth, contact Larry Cafiero at 

--- Fedora at free software workshop at KLN Madurai ---

Arun Sag conducted one day Free software workshop on 29th August, at KLN 
Madurai for the pre-final year CSE and IT students. The session started 
with an introduction to free software and philosophy. Fedora 11 was 
installed in 30+ Lab machines for hands on. The response from the 
students was excellent. Hospitality was good.

Fedora 11 DVDs were distributed to all the participants.

Arun would like to thank HOD of CSE department, KLN and final year 
student Dhivakaran for organizing this event successfully.

Pictures of the event [1]

--- Get on the map ---

Want to find the nearest ambassador? How about one in Belarus? Now you can.

Susmit Shannigrahi reports that finding out the nearest ambassadors, 
which was once a tedious task, is now as simple as viewing a map. The 
map is at here and instructions on how to place yourself on the map can 
be found at here.

--- Get the word out about your F11 event ---

Fedora 11 was released recently and with it a variety of activities 
around the release will be forthcoming. As such, with the upcoming 
release of Fedora 11, this is a reminder that posting your event on 
Fedora Weekly News can help get the word out. Contact FWN Ambassador 
correspondent Larry Cafiero at lcafiero-AT-fedoraproject-DOT-org with 
announcements of upcoming events -- and don't forget to e-mail reports 
after the events as well.

-- QualityAssurance --

In this section, we cover the activities of the QA team[1].

Contributing Writer: Adam Williamson

    1.  http://fedoraproject.org/wiki/QA

--- Test Days ---

Last week's main track Test Day[1] was on Sugar on a Stickthe 
Fedora-derived USB stick distribution which features the Sugar desktop 
environment that is the default desktop for the OLPC project. Not too 
many people showed up to test, but we did get a solid set of results, 
and this was the first test day to experiment with a new result 
reporting system based on the Semantic MediaWiki plugin.

This coming week is special from a Test Day perspective: it's Video Test 
Week! There will be not one but three main track Test Days, one for each 
of the major video adapter manufacturers. Wednesday 2009-09-09 is 
ATI/AMD Radeon Test Day[2]. Thursday 2009-09-10 is NVIDIA Test Day[3]. 
And last but not least, Friday 2009-09-11 is Intel graphics Test Day[4]. 
As always, graphics drivers are one of the most vital parts of the 
Fedora experience, and the three main drivers have received their usual 
round of significant changes since the last release, so we encourage 
everyone to come out on the appropriate Test Day for their hardware and 
help test. There will be live images available, so you don't need 
Rawhide - or even Fedora - installed to test: you just need to show up, 
download a live image, run some simple tests to see how well the 
graphics work, and report your results. This will help us immensely to 
make sure Fedora 12 has good support for as much graphics hardware as 
possible, so please do come along! Each Test Day will run all day and be 
held in Freenode IRC #fedora-test-day. If you're not sure how to use 
IRC, see this page[5].

Next week's Fit and Finish[6] project Test Day[7] will be on sharing - 
sharing files, printers, music, and even remote desktop functionality. 
This area is critical to many users but often overlooked, so please come 
along to help refine it! The Test Day will be held on Tuesday 2009-09-08 
in Freenode IRC #fedora-test-day.

If you would like to propose a main track Test Day for the Fedora 12 
cycle, please contact the QA team via email or IRC, or file a ticket in 
QA Trac[8].

--- Weekly meetings ---

The QA group weekly meeting[1] was held on 2009-08-31. The full log is 
available[2]. David Pravec reported that he had created the 
test-announce mailing list[3] for important QA and BugZappers event 

James Laska reported that he had not yet been able to talk to Liam Li 
about refining the install test plan to be more achievable within the 
timeframe for each snapshot release. He had improved the Dracut Test Day 
test cases. He had also spoken to Mike McGrath about the impact of 
nightly Rawhide images on the resources of alt.fedoraproject.org. Mike 
had not yet seen or had reported any major problems, but would like to 
be kept in the loop when new milestones are released. Adam Williamson 
asked if Infrastructure had any numbers for downloads of the nightly 
images. James did not know, but would ask.

Jesse Keating reported that he had built the new version of autotest for 
the AutoQA project to test. James Laska and Will Woods were in progress 
on testing it, and would report next week.

Will Woods reported on the progress of the AutoQA project. They had 
spent the week writing documentation, collected in the AutoQA category 
on the Wiki[4]. There are pages on how to write hooks and tests for 
AutoQA, and also pages on how AutoQA and autotest work. Will emphasized 
that no particular knowledge of how AutoQA itself works is required to 
write tests and hooks that can be used with it, and it's best to write 
tests and hooks before worrying about wrapper code to use them in 
AutoQA. In the coming week, they were planning to work on a method to 
get data back out of autotest to be used for projects like the 
israwhidebroken.com site.

James Laska did a Test Day update. He thanked those who had participated 
in the Dracut Test Day[5], and promised to send a summary to the mailing 
list soon. He noted that a sectool Test Day[6] was due the day after the 
meeting. Adam Williamson suggested some potential improvements to the 
Wiki page, and James asked him to send them to the mailing list so the 
Test Day organizer, Eduard Beneš, could update the page. The Sugar on a 
Stick Test Day was due the Thursday after the meeting, and noted that he 
and Sebastian Dziallas were working on getting the page ready, using the 
new Semantic system for reporting results. Finally, Adam Williamson 
noted that Graphics Test Week was coming the following week, and he was 
working on getting the pages created. He expected to be able to re-use 
many test cases from the Fedora 11 Test Days.

Kamil Paral brought up the idea of using zsync[7] to reduce the download 
weight of nightly Rawhide live images. Jesse Keating and Adam Williamson 
did not think it would result in much benefit, due to the way Fedora 
live CDs are implemented (as a single large filesystem image, rather 
than a set of package files). Will Woods suggested doing some tests to 
be sure, and Kamil said he would do this.

The group discussed the status of the proposed lower process 
capabilities feature for Fedora 12[8]. There was general concern that 
development of this feature was not sufficiently advanced for the 
current stage of Fedora 12 development. Fenris02 agreed to talk to the 
feature maintainer to see what could be done to avoid dropping the 
feature entirely for Fedora 12.

The Bugzappers group weekly meeting[9] was held on 2009-09-01. The full 
log is available[10]. Adam Williamson noted that some planned topics 
could not be discussed, as important people were not present: Brennan 
Ashton was not available to update on the triage metrics project, and 
Richard June was not present to update on the kernel triage project.

The group discussed the new test-announce mailing list[11]. Matej Cepl 
suggested that it be added to Gmane[12]. Adam Williamson promised to do 

Adam Williamson brought up the topic of Triage Days, which Edward Kirk 
had put on the agenda with a view to presenting some ideas on improving 
them. However, Edward was not at the meeting. No-one else had 
significant ideas on the topic.

The next QA weekly meeting will be held on 2009-09-07 at 1600 UTC in 
#fedora-meeting, and the next Bugzappers weekly meeting on 2009-09-08 at 
1500 UTC in #fedora-meeting.

--- Zsync feasibility ---

As discussed at the meeting, Kamil Paral tested[1] the practicality of 
using zsync[2] to reduce the size of nightly Rawhide live image 
downloads. He found that savings of between 30% and 60% were possible 
when testing the deltas between various nightly images.

    2.  http://zsync.moria.org.uk/

--- Installation testing SOP update ---

Liam Li announced[1] that he had updated the installation testing SOP 
draft[2], with improved instructions on summarizing test results.

--- Test Day summaries ---

Test Day summaries for Dracut[1] and Sectool[2] were provided by James 
Laska and Eduard Beneš respectively.


--- Mediawiki Semantic plugin testing ---

Mel Chua announced[1] that he had built a working Mediawiki test 
instance with the Semantic extension[2] installed, for the purpose of 
implementing an improved test result reporting system. He linked to a 
meeting log[3] which documented the implementation. He noted that the 
upstream project were interested in having Fedora's use of the Semantic 
system documented, and asked if anyone would be willing to work on this.

-- Translation --

This section covers the news surrounding the Fedora Translation (L10n) 

Contributing Writer: Runa Bhattacharjee

    1.  http://fedoraproject.org/wiki/L10N

--- Transifex Version Upgrade on translate.fedoraproject.org ---

The version of Transifex used in translate.fedoraproject.org is set to 
be updated soon to v.0.7.2 (to be released next week) . Diego Búrigo 
Zacarão informed[1] about the modifications that are going to be made by 
Mike Mcgrath next week, that would enable higher number of connections 
to translate.fedoraproject.org. However, considering that the 
translation deadline for Fedora 12 is set for 22nd September 2009, the 
version upgrade may happen after the translation due date.


--- Translations for Transifex Moved to www.transifex.net ---

The translations for the Transifex module would not be accepted from 
translate.fedoraproject.org anymore[1]. This module has now been moved 
to www.transifex.net .


--- RPM Module Removed ---

The RPM module is at present not available for translations[1], due to 
some errors and has been removed from the 'Various' collection in 


--- New Members in Fedora Localization Project ---

Filip Slunecko[1] (Czech), and Marila Latini[2] (Italian) joined the 
Fedora Localization Project last week.


-- Artwork --

In this section, we cover the Fedora Design Team[1].

Contributing Writer: Nicu Buculei

--- A Chilean Logo ---

As Jonathan Barrios, from the Chile community, asked[1] for a 
personalized artwork for a local event, "I think here I can get some 
help to make the logo for Fedora Linux Day - Chile and one poster to 
promotion this event", Charles R. Sutton proposed a first try[2] as a 
new contributor and after an in-depth research of the logo usage 
guidelines[3] he followed[4] with a new, complying, version. A bit 
later, María Leandro proposed another version[5] "Something like this? 
Remember that those are 2 proposals; you should pic only one. I like 
most the one at bottom" which apparently made everyone happy[6] "that is 
perfect. I prefer the one on the bottom as well. Great work!"

---- KSM Tuning Service ----

A new feature for Fedora 12, Kernel Samepage Merging[1], enables KVM 
guest virtual machines to share identical memory pages. This is 
especially useful when running multiple guests from the same or similar 
base operating system image. Because memory is shared, the combined 
memory usage of the guests is reduced. KSM works by scanning memory, 
looking for identical pages.

Dan Kenigsberg posted[2] a KSM control daemon in a "simple script that 
controls whether (and with what vigor) should ksm search duplicated 
memory pages."

"An unattended host running a variable number of qemu-kvm's needs to 
tune ksm automatically, since when memory is tight, it's better to spend 
more cpu on merging pages. In more relaxed cases, it's just a waste of

---- Host Iptables Settings for Bridged Guests ----

Mark McLoughlin pointed[1] out that the recommended[2] means of 
configuring iptables on the host to allow traffic to pass to a bridged 
guest is to disable netfilter on the bridge altogether.

  # cat >> /etc/sysctl.conf <<EOF
  net.bridge.bridge-nf-call-ip6tables = 0
  net.bridge.bridge-nf-call-iptables = 0
  net.bridge.bridge-nf-call-arptables = 0
  # sysctl -p /etc/sysctl.conf

This "will be the default with Fedora 12."

---- Xen Domain0 Kernels ----

Until support for pv_ops[1] is added to the upstream kernel (F13?), it 
takes some twiddling to host Xen guests on Fedora. Even then it isn't 
recommended for anything more than experimentation at this time. More 
adventurous users are reporting some success with experimental kernels 
and running a Xen dom0.[2] [3] [4]

Current dom0 kernel options include building[5] one from Jeremy 
Fitzhardinge's git repository or installing[6] Brian Young's RPM.
