Welcome to Fedora Weekly News Issue 269[1] for the week ending March 30, 2011. What follows are some highlights from this issue.
This issue begins with announcements from the Fedora Project, including changes to the packaging guidelines and an additional week slip of the Fedora 15 release date. One article for Fedora In the News this week from PC World on Red Hat's financial success. In Ambassador news, details on new members of the team, a summary of discussion on the Ambassador and FAmSCo lists, and a couple event reports. In Quality Assurance news, details on the latest and upcoming Test Days on power management, printing and ABRT, as well as various reports leading up to the Fedora 15 beta release. Security Advisories brings us current with the security-related package releases this past week for Fedora 13, 14 and 15, and in our Latin American beat this week, a second installment of Guillermo Gomez's Ruby Primer, in Spanish.

---- Changes to the Packaging Guidelines ----
Tom 'Spot' Callaway announced[1],
"Here are the changes to the Fedora Packaging Guidelines for this week:
The Packaging:PHP guidelines have been updated to reflect that PEAR documentation provided by upstream are installed in %{pear_docdir}, should stay there, and must be marked as %doc.
Additionally, the definition of pear_docdir has been defined as %{_docdir}/pear.
https://fedoraproject.org/wiki/Packaging:PHP
---
The Java guidelines have been updated to add information and sample template for Maven 3 (Fedora 15+).
https://fedoraproject.org/wiki/Packaging:Java
---
These guidelines (and changes) were approved by the Fedora Packaging Committee (FPC).
Many thanks to Remi Collet, Stanislav Ochotnicky, and all of the members of the FPC, for assisting in drafting, refining, and passing these guidelines.
As a reminder: The Fedora Packaging Guidelines are living documents! If you find something missing, incorrect, or in need of revision, you can suggest a draft change. The procedure for this is documented here [2]
Thanks,
~spot"

---- Fedora 15 schedule to slip an additional week ----
Jared K. Smith announced[1]
"The Fedora 15 development cycle is well under way, and making good progress. Yesterday I met[1] with Release Engineering, QA, the Fedora Program Manager, and we decided that in order to accommodate some late-breaking changes, we're going to need to slip the Fedora 15 release schedule by a week in order to have adequate time to do proper testing of the candidate images before the Beta. This slip will affect the entire Fedora 15 development cycle, as shown in the chart below:
o F15 Devel Start 2010-11-02
o Feature Submission Deadline 2011-01-25
o Feature Freeze 2011-02-08
o Branch From Rawhide 2011-02-08
o Software String Freeze 2011-02-15
o Alpha Change Deadline 2011-02-15
o Alpha Release 2011-03-08
N O W -----------------------
o Software Translation Deadline 2011-04-05
o Beta Change Deadline 2011-04-05
o Features 100% Complete 2011-04-05
o Beta Release 2011-04-19
o Final Change Deadline 2011-05-09
o Compose RC 2011-05-10
o GA 2011-05-24
Robyn Bergeron has also kindly updated the complete break-out of the Fedora release schedule, which is available[2]. If you have any questions or concerns, please don't hesitate to let me know.

--- Fedora Events ---
The purpose of event is to build a global Fedora events calendar, and to identify responsible Ambassadors for each event. The event page is laid out by quarter and by region. Please maintain the layout, as it is crucial for budget planning. Events can be added to this page whether or not they have an Ambassador owner. Events without an owner are not eligible for funding, but being listed allows any Ambassador to take ownership of the event and make it eligible for funding. In plain words, Fedora events are the exclusive and source of marketing, learning and meeting all the fellow community people around you. So, please mark your agenda with the following events to consider attending or volunteering near you!
---- Upcoming Events (March - May 2011) ----
* North America (NA)[1]
* Central & South America (LATAM): [2]
* Europe, Middle East, and Africa (EMEA)[3]
* India, Asia, Australia (India/APJ)[4]

--- Red Hat Proves That Open Source Is Good for Business (PC World) ---
Rahul Sundaram forwarded[1] a posting on Red Hat's financial success:
"Critics of free and open source software are fond of making the argument that software must be locked up, patented and jealously guarded if it is to serve as the basis for a successful business. Well, Red Hat just refuted such claims in a big way this week with its fourth quarter earnings report, which blew away analysts' expectations and placed the company well on track for billion-dollar revenues in the upcoming year."
Based in North Carolina, Red Hat is the company behind both the Fedora and the Red Hat Enterprise Linux (RHEL) Linux distributions. Fedora is the free, community version of the software, while RHEL is sold as acommercial product with support and services."

--- Test Days ---
Thursday 2011-03-24 was power management Test Day[1]. The event produced a great turnout of testers who provided results on a wide range of hardware, and the developers are already looking at the bugs filed. Thanks to everyone who came out to help.
This Tuesday, 2011-03-29, was printing Test Day[2]. The turnout was a little smaller than we hoped, but the testers who did come managed to find lots of bugs, and Fedora's printing maintainer, Tim Waugh, was very happy with all the results.
This Thursday, 2011-03-31, will be ABRT Test Day[3]. As well as checking that ABRT (Fedora's automated crash report tool) is working as expected for Fedora 15, we'll be testing out a big new feature, the retrace server[4]. This allows you to submit crash reports to a remote server which will generate the backtrace - avoiding the need for you to download and install often large debuginfo packages in order to submit reports. Please come along and help us test this exciting new feature!
There is currently no Test Day planned for next Thursday, 2011-04-07. Take the day off!

--- Anaconda testing ---
James Laska requested testing of an installer image which included updated versions of anaconda and lorax that needed testing before being approved as stable updates[1]. Several testers responded, and the updates were soon approved.
1. ↑ http://lists.fedoraproject.org/pipermail/test/2011-March/098018.html
--- GNOME Tweak Tool testing ---
Michel Salim announced that GNOME Tweak Tool, an application for tweaking various advanced settings in GNOME 3, was now available for testing[1]. Several group members thanked Michel for the announcement and provided feedback on the tool.
1. ↑ http://lists.fedoraproject.org/pipermail/test/2011-March/098107.html
--- Fedora 15 Beta preparation ---
The third Beta blocker/nice-to-have review meeting took place on 2011-03-25[1], and the team worked through the full list of proposed Beta blocker and nice-to-have bugs. The first test compose was scheduled for Tuesday 2011-03-22, but could not be completed on that day due to various outstanding bugs and the lack of the planned NetworkManager 0.9 packages. At a special release schedule meeting on Wednesday 2011-03-23[2], the QA and release engineering teams, and the Fedora Project Leader, agreed that the late arrival of NetworkManager 0.9 justified a one week slip in the release schedule. The first test compose was then set for Tuesday 2011-03-29.

--- Improving pre-release download page ---
Tim Flink passed on some feedback[1] he had received from a new tester who had downloaded a pre-release and asked some questions in the #fedora IRC channel, which does not handle pre-release issues. He suggested that it would be a good idea to add some text to the pre-release download page[2] explaining the right places to go to post feedback and get help with pre-release issues. Jóhann Guemundsson and Adam Williamson both suggested filing a request with the websites team, and Tim reported[3] that he had filed a ticket[4].

-- LATAM Fedora! --
LATAM Fedora is a regular column of Spanish language contributions around open source software. It is our first expansion into incorporating foreign language content into FWN.
This week's contribution is from Guillermo Gómez, a second installment primer on Ruby. Enjoy!
---- Ruby Capítulo 2 : Una clase algo más completa ----
Siguiendo nuestra secuencia al estilo tutorial, en esta edición vamos a completar un poco más nuestras clases, introduciresmo los conceptos de métodos y variables de clase.
Una variable de clase es una variable compartida de la clase misma. Sólo existe una copia de una variable de clase en particular para una clase dada. Los nombres de las variables de clase comienzan con @@ tal como en @@reproducciones.
1 class Cancion
2 @@reproducciones = 0
3
4 def Cancion.reproducciones
5 @@reproducciones
6 end
7
8 def reproducir
9 @@reproducciones =+ 1
10 end
11 end
A diferencia de las variables de instancia y variables globales, las variables de clase deben se inicializadas antes de poder ser utilizadas, usualmente se hace con una declaración simple en el cuerpo de la definición de la clase. En el código anterior igualmente se ha introducido el concepto de método de clase. Un método de clase es un método que no necesita que se instancie la clase para ser invocado, es decir, "son métodos propios de la clase y no de sus objetos".
Su utilidad es obvia en el ejemplo, se quiere saber cuántas reproducciones se han hecho en total en nuestro reproductor de música. Esta información no es específica a una canción en particular, es decir, no es sujeto de las instancias sino de la clase misma. La diferencia al momento de declarar el método de clase es que debe anteponer el nombre de la clase al método, tiene dos opciones, o usar explícitamente Cancion, o self. El uso de *self" da mayor flexibilidad ya que permite cambiar el nombre de la clase sin mayores traumas.
1 class Cancion
2 @@reproducciones = 0
3
4 def self.reproducciones
5 @@reproducciones
6 end
7
8 def reproducir
9 @@reproducciones =+ 1
10 end
11 end
---- Constantes vs variables ----
Las variables y constantes en Ruby mantienen referencias a objetos. Las variables no poseen un tipo intrínseco, a cambio el tipo es únicamente definido por los mensajes a los que responde el objeto referenciado.
Una constante en Ruby también es una referencia a un objeto. Las constantes son creadas cuando son asignadas por primera vez, a diferencia de otros lenguajes Ruby le permite alterar el valor de las constantes si bien ello provocará un mensaje de alerta. En general usted no debe alterar una constante en tiempo de ejecución y debería evitarlo a toda costa.
1 >> MI_CONSTANTE = 1
2 => 1
3 >> MI_CONSTANTE = 2
4 (irb):23: warning: already initialized constant MI_CONSTANTE
5 => 2
Note como las constantes pueden declararse dentro de la definición de clase lo que nos lleva a la definición de constante de clase y a la noción de espacios de nombres por la forma en que nos referimos a dichas constantes.
1 class Cancion
2 VERSION="1.0"
3 end
1 >> Cancion::VERSION
2 => "1.0"
3 >> VERSION
4 => "1.8.7"
Note que VERSION no referencia ni colisiona con Cancion::VERSION.
---- El poder de herencia ----
Tal vez el santo grial de la programación es el principio DRY, "Don Repeat Yourself". Una forma de evitar repetirse, es escribir código reusable, cada vez que estamos escribiendo nuevo código y tenemos esa sensación de deja-vu de que ya esto lo hicimos una vez en el pasado, es porque no estamos reusando nuestro código de forma inteligente. En POO la herencia es una excelente forma de mantener el código reusable sin mayores repeticiones.
La herencia le permite crear clases que sean refinamientos o especializaciones de otra clase. Por ejemplo, y siguiendo el ejemplo de Cancion en nuestro reproductor de música ahora a alguien se le ocurrió que sería interesante que se incluyera el soporte para canciones de tipo Karaoke. La única diferencia con las otras canciones es que las canciones Karaoke tienen asociadas la letra de la canción en conjunto con infomación de sincronización para reproducir las letras del Karaoke en nuestro flamante reproductor ahora con una gran pantalla de video.
1 class Karaoke < Cancion
2 def initialize(nombre, artista, duracion, letra)
3 super(nombre, artista, duracion)
4 @letra = letra
5 end
6 end
El "< Cancion" en la definición de la clase le indica a Ruby que Karaoke es un subclase de Cancion, o en dirección opuesta, Cancion es la superclase de Karaoke. De esta forma la clase hija hereda todos los métodos y declaraciones de variables de su padre. Al invocar un método sobre un objeto o clase, Ruby defiere su ubicación hasta el momento de ejecución, en dicho momento Ruby primero mira en la clase para determinar si existe el método invocado, si no es así, intenta en el padre, y así atravesando todos los ancestros de la clase hasta ubicar el método invocado. Si se acaban los ancestros donde buscar, Ruby ejecuta una acción especial que puede ser interceptada si se desea Object#method_missing, si no, produce un error.
Cada clase especializada maneja sus detalles, para el resto se utiliza super, es decir, el método del padre o de su ancestro. De esta forma, por ejemplo, en nuestra definición de Karaoke#initialize dejamos que la inicialización de todo lo común a Cancion ocurra igual que antes por medio de la llamada a super con los respectivos parámetros necesarios, luego inicializamos los datos específicos a nuetras clase Karaoke.
---- Espacios de nombres ----
En la medida que escriba programas Ruby cada vez más grandes, usted naturalmente se encontrará con código reusable, librerías de rutinas relacionadas entre sí por ejemplo. Usted deseará separar dicho código en distintos archivos separados de tal forma que el contenido pueda ser reusado entre diferentes programas Ruby. Frecuentemente este código será organizado en clases.
Otras veces ello simplemente no es conveniente o no aplica, son un grupo de métodos que desea reusar, usted puede simplemente colocarlos en un archivo y cargar dicho archivo en su programa con load o require. Esto funciona pero tiene un problema, digamos que se crea una librería para cocinar con los métodos calentar , mezclar, amasar en un archivo cocina.rb y otra librería para atletas con los métodos calentar, correr, descansar en el archivo atleta.rb. Si carga ambos archivos uno después del otro, simplemente el método calentar colisiona y sólo el más recientemente cargado tendrá la definicón actual del método, el otro simplemente será olvidado, en resumen la colisión en los nombres es el problema.
La respuesta es el mecanismo de modulos. Los modulos definen un espacio de nombres en donde sus métodos y constantes pueden aplicar sin tener que preocuparse en colisionar con otros métodos y constantes:
1 module Cocina
2 ESCUELA="Latinoamericana"
3 def Cocina.calentar(x)
4 # Se espera que x sea un valor númerico para representar temperatura en oC
5 # ..
6 end
7 ...
8 end
9
10 module Atleta
11 ESCUELA="Simón Bolívar"
12 def Atleta.calentar(t)
13 # Se espera que t sea un valor numérico que represente tiempo en segundos
14 # ..
15 end
16 end
1 >> Cocina::ESCUELA
2 => "Latinoamericana"
3 >> Atleta::ESCUELA
4 => "Simon Bolivar"
5 >> include Atleta
6 => Object
7 >> Atleta.calentar(1000)
8 calentando 1000 segundos
9 => nil
10 >> include Cocina
11 => Object
12 >> Cocina.calentar(10)
13 => 10
Ahora entonces tiene mucho menos probabilidades de provocar colisiones, note que debe cargar el código, y luego include para usar las funcionalidades del módulo.
---- Herencia múltiples vs Mixins ----
Algunos lenguajes orientados a objetos, tales como C++, soportan herencia múltiple en donde una clase puede tener más de una superclase heredando funcionalidad de cada una de ellas. Si bien potente, esta técnica puede ser peligrosa ya que la jerarquía puede tener ambigüedades. Otros lenguajes como java y C# soportan sólo herencia simple. Si bien más limpia y simple, la herencia simple también tiene sus desventajas, en la realidad los objetos heredan atributos de múltiples fuentes en el mundo real.
Ruby ofrece una alternativa interesante y poderosa que le ofrece la simplicidad de la herencia simple y el poder la herencia múltiple. Una clase Ruby tiene una única clase padre, en consecuencia Ruby es un lenguaje con herencia simple, sin embargo, las clases Ruby pueden incluir la funcionalidad de cualquier cantidad de mixins (un mixin es una especie de definición parcial de clase). Nuevamente dejemos que Ruby hable, creemos nuestro archivo con la definición de módulo y un par de clases tontas que lo usen como mixin:
---- mixin_module.rb ----
1 module Debug
2 def quien_soy?
3 "#{self.class.name} (\##{self.objet_id}): #{self.to_s}"
4 end
5 end
6
7 class Cocina
8 include Debug
9 def estilo
10 puts "Italiana"
11 end
12 end
13
14 class Nevera
15 include Debug
16 def capacidad
17 puts "150 pies cúbicos"
18 end
19 end
Si ahora cargamos dichas definiciones de módulo y clases en irb, podemos evidenciar y experimentar con el uso de los mixins (note que le voy a pasar la forma de hacerlo):
1 $ irb
2 >> load 'mixin_module.rb'
3 => true
4 >> nevera = Nevera.new
5 => #<Nevera:0xb7587b38>
6 >> cocina = Cocina.new
7 => #<Cocina:0xb7585c5c>
8 >> nevera.quien_soy?
9 => "Nevera (#-609469028): #<Nevera:0xb7587b38>"
10 >> cocina.quien_soy?
11 => "Cocina (#-609472978): #<Cocina:0xb7585c5c>"
Bien, es todo por hoy, nos recontraremos en un tercer capítulo dedicado a métodos en una próxima edición de esta serie dedicada a aprender Ruby.
Este artículo se mantiene en línea en gomix.fedora-ve.org para posibles mejoras y erratas.

[Guidelines Change] Changes to the Packaging Guidelines
by Tom Callaway
Here are the changes to the Fedora Packaging Guidelines for this week:
---
The Packaging:PHP guidelines have been updated to reflect that PEAR
documentation provided by upstream are installed in %{pear_docdir},
should stay there, and must be marked as %doc.
Additionally, the definition of pear_docdir has been defined as
%{_docdir}/pear.
https://fedoraproject.org/wiki/Packaging:PHP
---
The Java guidelines have been updated to add information and sample
template for Maven 3 (Fedora 15+).
https://fedoraproject.org/wiki/Packaging:Java
---
These guidelines (and changes) were approved by the Fedora Packaging
Committee (FPC).
Many thanks to Remi Collet, Stanislav Ochotnicky, and all of the members
of the FPC, for assisting in drafting, refining, and passing these
guidelines.
As a reminder: The Fedora Packaging Guidelines are living documents! If
you find something missing, incorrect, or in need of revision, you can
suggest a draft change. The procedure for this is documented here:
https://fedoraproject.org/wiki/Packaging/Committee#GuidelineChangeProcedure

Welcome to Fedora Weekly News Issue 268[1] for the week ending March 23, 2011. What follows are some highlights from this issue.
Our issue opens with announcements, including details on Fedora being accepted into the 2011 Summer of Code, as well as notice of some changes to the packaging guidelines. We're looking for a permanent writer for the Marketing beat, but we have a short beat this week that includes weekly team meeting minutes and some thoughts on expanding the SXSW Fedora photobooth to other FAmNA events. This week's In the News beat has a whopping ten articles on Fedora 15, Gnome 3 and other topics, and Ambassadors brings us current on happenings in that team as well as FAmSCo. In QA news, details on this past week's Test Day on preupgrade, today's Power Management Test Day, and next week's ABRT Test Day as well as other working on Fedora 15. Security Advisories offers the latest security-related packages for Fedora 13-15, and our issue finishes up with another LATAM installment of Spanish FLOSS goodness from Guillermo Gomez, this week on the audio manipulation package, SOX. Read on!
An audio version of some issues of FWN - FAWN - are available! You can listen to existing issues[2] on the Internet Archive. If anyone is interested in helping spread the load of FAWN production, please contact us!

---- Fedora accepted in to Google Summer of Code 2011! ----
Ryan Rix on Sat Mar 19 06:45:46 UTC 2011 announced[1],
"Heya folks :)
So... after a year's hiatus, Fedora's been accepted in to Google's Summer of Code program for summer 2011!
If you're a university student looking for a job this summer, start thinking about some awesome idea that you'd like to make happen in Fedora this summer. Applications will open March 28, so start talking with developers in IRC and mail, and find something awesome to do! We have a list of some ideas at: [2] but don't limit yourself to that list. Find a mentor, and make your idea happen!
Mentors should apply to be a mentor[3] in Google's Melange instance. be inviting those who are listed on the Ideas page. We've still some work to do before the student applications open, some scaffolding to build, and some things to decide, so please join in. I'll be sending mentors more information soon.
we're listed as The Fedora Project
Congratulations, everyone, for the Awesome we're doing!"

---- [Guidelines Change] Changes to the Packaging Guidelines ----
Tom Callaway on Tue Mar 22 01:40:43 UTC 2011 announced[1],
"Here are the latest set of changes to the Fedora Packaging Guidelines:
---
The Emacs packaging guidelines were updated to handle cases where a package's principal functionality does not require (X)Emacs, but the package also includes some auxiliary Elisp files to provide support for the package in (X)Emacs.
[2]
---
The Scriptlet Snippets section dealing with the order that scriptlets are invoked has been updated to include %trigger scripts.
[3]
---
A subsection was added to the Packaging Guidelines section on Filesystem Layout in which it is made explicit that binaries in /bin or /sbin must NOT depend on any libraries in /usr/lib or /usr/lib64.
[4]
---
The section on Epochs was improved, and clarifying language about Epoch use in Requires was added to the Packaging Guidelines.
[5] [6]
---
New guidelines were added covering the packaging of Ada programs. [7]
---
The section on Boostrapping in the Treatment of Bundled Libraries page in the Packaging Guidelines has been amended to add the following:
Packages which are built in such a bootstrapping mode must not be tagged for a final release (or pushed as an update for any stable release). FPC will track the progress of approved bootstrapping exceptions via the ticket requesting the bootstrap bundling exception.
[8]
---
Macro forms of system executables (such as %{__rm}) should not be used except when there is a need to allow the location of those executables to be configurable.
[9]
---
These guidelines (and changes) were approved by the Fedora Packaging Committee (FPC).
Many thanks to Hans Niedermann, Jonathan Underwood, Pavel Zhukov, and all of the members of the FPC, for assisting in drafting, refining, and passing these guidelines.
As a reminder: The Fedora Packaging Guidelines are living documents! If you find something missing, incorrect, or in need of revision, you can suggest a draft change. The procedure for this is documented here: [10]"

---- Your package translation ----
Noriko[1] on Mon Mar 21 23:57:43 UTC 2011 announced[2],
"Dear Fedora package maintainers
Could you all please take a few minutes and check if your packages are on the list[3]and set to allow Fedora Localization Project to translate?
* setuptool: [4]
* pam_krb5: [5]
* pkinit-nss: [6]
* The above packages are on the list but do not allow Fedora Localization teams to upload the translated files. This means that these
packages will not receive any translation from FLP. Please change the setting to allow FLP, or advise us if the maintainers choose having their own translation teams. In that case, the packages may be removed from the list of Fedora Project on tx.net."

---- Fedora Events ----
The purpose of event is to build a global Fedora events calendar, and to identify responsible Ambassadors for each event. The event page is laid out by quarter and by region. Please maintain the layout, as it is crucial for budget planning. Events can be added to this page whether or not they have an Ambassador owner. Events without an owner are not eligible for funding, but being listed allows any Ambassador to take ownership of the event and make it eligible for funding. In plain words, Fedora events are the exclusive and source of marketing, learning and meeting all the fellow community people around you. So, please mark your agenda with the following events to consider attending or volunteering near you!
----- Upcoming Events (Dec 2010 - Feb 2011) -----

--- SxSW photobooth awesomeness and its future ---
Clint Savage discussed[1] strategies for making the "SxSW photobooth awesomeness and its future" more universal to FAmNA events.
"As you probably know, I've been hanging around Fedora for a few years now. I helped improve the events that Fedora attends by creating the Fedora EventBox. It's been going really well, but this week, I saw a big improvement because of just a few people at SxSW. I would like to thank Mo, Emily, Spot, Jared and anyone else who helped make the booththere awesome!
. . .
But there's more we can do with this, and that's where I think the value lies. For one, it is cool that each participant get's a nice little card printed right there with a QR code so they can go retrieve it. But it would also be nice to let them share their photos on social networking sites like Facebook, identi.ca, foursquare, twitter, etc. I can also see gaining contributors from this concept, in that they are now 'part' of Fedora's legacy. Maybe having them show up on the FedoraProject front page when an event is happening? I seriously think that this is stuff that everyone in Fedora would love."

--- Tim Burke: Ext4 Is Not Going Anywhere Any Time Soon (muktware.com) ---
Rahul Sundaram forwarded[1] a posting on btrfs and its relation to ext4 in RHEL and Fedora:
"Red Hat engineers work actively to develop these features in the upstream kernel, work both with the Fedora community and others to integrate them for early adopters and then evaluate when they are robust enough for enterprise users."
"File systems are very long lived in the field since users tend to maintain them for years and years. In many cases, enterprise users have external storage so the storage will survive several generations of servers. That means that ext4 is not going anywhere any time soon! That said, Red Hat is an active contributor to the btrfs project and we are actively working on getting some of the key inhibitors for wide btrfs deployment finished with the upstream community"

--- Linux shakedown: Testing both GNOME 3 and Fedora 15 (ZDNetAsia.com) ---
Rahul Sundaram forwarded[1] a very positive article on both Fedora 15 Alpha and Gnome 3:
"Because this release was so focused on GNOME 3, it was hard to even really notice Fedora 15 in the background. That says a lot about where Fedora is heading. The OS, underlying the desktop, was about as solid an alpha release as I have ever laid fingers on. And running from the live CD was incredible--if someone were to sit at this computer (the very PC I am writing this article on) and begin using the desktop, they would never know they were using a Live CD.
I realize that many of you look down on Fedora for one reason or another. But this testing release should not go unnoticed by the IT public. The GNOME 3 testing release of Fedora 15 is crucial to the growth of both Fedora and GNOME. This release will go a very long way in the testing of what will soon become the default desktop for many Linux distributions (for a very long time). So please, do your fellow Linux community members a favor...test this release and submit bug reports. Your help will be much appreciated and long remembered."

--- Fedora 15 vs Ubuntu Natty Narwhal – The Battle for Your Next Desktop (maketecheasier.com) ---
Rahul Sundaram forwarded[1] another review of Fedora 15 Alpha and the next version of Ubuntu:
"Fedora boasts a pretty “enterprisey” software set. You’re more likely to find a fancy new virtualization program than a 3D shooter here. That’s not to say it’s inappropriate for desktop use, quite the opposite, but expect to find some applications that might not be of much interest to a casual PC user. Still, for those who do like to know, you can expect to find:
* LibreOffice, a “freer” fork of OpenOffice
* BoxGrinder, a virtual appliance utility
* Robotics Suite, a set of tools for robot enthusiasts
* Sugar, a specialized desktop environment for education
* Dynamic Firewall, a way to interactively manage your system firewall
* Gnome 3, of course"

--- Using SELinux and iptables Together (Linux.com) ---
Rahul Sundaram forwarded[1] an article by Red Hat SELinux engineer, Dan Walsh:
"One of the things I have wanted to do with SELinux for years is figure out a way to make SELinux and iptables work together, but each time I looked at it, my use cases became too complicated. James Morris and Paul Moore worked on a tool called Secmark way back in the Red Hat Enterprise Linux (RHEL) 5 time frame. My simple implementation of Secmark is to use iptables rules to define labels on packets as they flow within an SELinux system."

--- Out with Windows 2000, in with Fedora 14, part 2 (ZDNet UK) ---
Rahul Sundaram forwarded[1] part two of an article from a user who replaces Windows 2000 with Fedora 14 on an older PC:
"Other than these issues, the PC is running great and in fact they immediately noticed a significant speed increase in running their applications. I was surprised that still some tweaks were needed, but when dealing with proprietary hardware/software, we will continue to see these types of problems. My best advice is to direct new users to the Fedora Forums which are very understanding for new users."

--- Speedy 'Wonder Patch' Debuts in New Linux Kernel (PC World) ---
Rahul Sundaram forwarded[1] about the debut of a new patch that increases the linux kernel speed significantly, and which will be available in Fedora 15:
"Back in November I wrote about the 233-line patch that was expected to bring a huge speed boost to version 2.6.38 of the Linux kernel, and that's just what made its widely anticipated debut on Monday night"

--- Fedora shows off Gnome 3.0 (mybroadband.com South Africa) ---
Rahul Sundaram forwarded[1] some commentary on Gnome 3.0 in Fedora 15:
"The switch to the Gnome 3.0 desktop is the most notable change in this release and one that will no doubt prompt the most discussion. The Gnome 3.0 desktop is a radical departure from the Gnome 2.0"

--- Fedora 15 alpha debuts GNOME 3, adds cloud appliance builder (DesktopLinux.com) ---
Rahul Sundaram forwarded[1] another look at Fedora 15 Alpha and Gnome 3:
"The Systemd configuration management technology was available as a technology preview in Fedora 14, but now replaces Upstart and SystemV init as the default initialization system. Systemd is claimed to speed boot-time as well as to provide on-demand loading and unloading of services. Touted Systemd features include system state snapshoting, as well as the ability to track processes, daemons, and sockets.
In the Lovelock alpha, a dozen desktop daemons have been converted to use Systemd service files, while a small number of programs have been patched to take advantage of it, says the Fedora project. Systemd is said to be compatible with legacy SysV init script
For those Fedora users with their heads in the cloud, one of the more interesting additions is BoxGrinder, touted as "an easy to use command line tool to create appliances (virtual images) from simple plaintext application files." BoxGrinder is available for platforms including KVM, Xen, VMware, and EC2, says the project"

--- My Wife Loves Gnome 3 (muktware.com) ---
Rahul Sundaram forwarded[1] a non-technical user's experience with Fedora 15 and Gnome 3:
"The most important remark for Gnome 3 came from a non-techie. A user who doesn't much care about kernels and mutters; someone who uses computer to do her job. My wife was sitting right behind me when the machine booted. "Wow...what's that!" I heard someone from behind. I turned and found her looking at my machine. "Is it a new OS? It looks cool!"
I was amazed. As a regular user I was a bit upset with Gnome 3 fearing it will break my usage pattern and here was an ordinary user who was impressed by the new design and approach."

--- Playing With Fire, Fedora 15 and Gnome 3 (muktware.com) ---
Rahul Sundaram forwarded[1] another posting from muktware.com on Fedora 15 and Gnome 3 experience:
"I love the design, look and feel of Gnome 3. I am worried about is how is it going to affect my productivity, but I don't want to be too negative before I see the final product. It may just be the status-quo factor bugging me. I don't know. I may end up loving it, the way I love KDE 4!"

--- Test Days ---
Thursday 2011-03-17 was preupgrade Test Day[1]. A good group of testers showed up, but testing was somewhat complicated by underlying bugs in anaconda. However, the testers were able to check that most of preupgrade itself was working as intended. Rui He posted a recap to the list[2].
This Thursday, 2011-03-24, is power management Test Day[3], where we'll be testing how well various common power management operations work on a range of systems. The main focus of this event is to check common power management features on a wide range of hardware, so we really need as many people as possible to come along. Please come out if you have a bit of spare time.
Next Tuesday (note the special day!), 2011-03-29, will be printing Test Day[4]. We'll be aiming to test out Fedora 15's printing stack with as many different printers as possible, so if you have a printer and a pulse, please come and join us!
Next Thursday, 2011-03-31, will be ABRT Test Day[5]. As well as checking that ABRT (Fedora's automated crash report tool) is working as expected for Fedora 15, we'll be testing out a big new feature, the retrace server[6]. This allows you to submit crash reports to a remote server which will generate the backtrace - avoiding the need for you to download and install often large debuginfo packages in order to submit reports. Please come along and help us test this exciting new feature!

--- Release criteria revisions ---
Adam Williamson proposed several alterations to the release criteria[1], covering several issues that had become clear at recent blocker meetings. The alterations attempted to account for bugs that were specific to particular keymaps or languages, cover firstboot, cover unintended installations, and clarify a few other points. Andre Robatino proposed an additional criterion requiring a working media check process in the installer[2], an idea Adam supported[3]. James Laska recommended caution to avoid tying the criterion too closely to a specific implementation[4].

--- Nightly builds via Koji ---
In response to a query from Gregory Woodbury about nightly builds being stalled[1], Kevin Fenzi explained[2] that this was due to a problem on the compose machine. He went on to announce that the nightly builds would soon be done via Koji, which will result in the builds happening much faster, guarantee that they are built in exactly the same way as official composes, and allow for an archive of recent nightly builds to be kept, making regression testing easier.

--QA group governance
Jóhann Guðmundsson raised some questions regarding the governance of the QA group[1], including the idea of an elected board to handle some decision making when representing the group as a whole. Stephen Smoogen noted that SIGs do not generally have formal voting structures[2], while leaving open the question of whether QA is (or should be) a SIG or a Steering Committee. Clyde E. Kunkel noted that the functions of the QA team are mostly advisory rather than decision-making, and expressed a desire for an organization chart (or 'wiring diagram') for the various groups that make up the Fedora project[3]. Adam Williamson pointed out that the Board had worked on such a diagram at FUDCon Tempe, and a copy of the image may be available[4]. He replied to Jóhann's question about the status of Red Hat employees in the group by saying they tried not to see their position as giving them automatic decision-making power on behalf of the group, but admitted that in practice, other groups often seem to come directly to the Red Hat employees in the group and consider their responses as representing the QA group as a whole.

--- Fedora 15 Beta preparation ---
The second Beta blocker/nice-to-have review meeting took place on 2011-03-18[1], and the team worked through the full list of proposed Beta blocker and nice-to-have bugs. The first automated Beta acceptance test run was scheduled for 2011-03-17, but this was not possible due to underlying issues in anaconda at the time, as discussed at the weekly meeting of 2011-03-21[2]. At the same meeting, James Laska noted that the Beta test compose was at risk due to the same problems, and committed to providing updated images to test candidate fixes for the problems.

-- LATAM Fedora! --
LATAM Fedora is a regular column of Spanish language contributions around open source software. It is our first expansion into incorporating foreign language content into FWN.
This week's contribution is from Guillermo Gómez, a primer on the SOX audio manipulation package. Enjoy!
--- SOX ---
SoX[1], la navaja suiza para la manipulación de audio.
---- Agregando Soporte mp3 y m4a ----
Fedora no incluye soporte para MP3 en sus paquetes multimedia, debido a problemas de patentes sobre el algoritmo que permite comprimir y descromprimir mp3. De forma similar ocurre con el formato m4a. Sin embargo usted puede vivir en ciertos países donde no apliquen las limitaciones de la legislación de los EEUU, entonces si es así, veamos cómo podemos agregar el soporte deseado para mp3 y m4a entre otros formatos a sox.
---- Agregar soporte recompilando el Source RPM (SRPM) ----
----- Requisitos -----
* Herramientas para compilación
* rpmbuild
* yum-buildep
* De RPM Fusion, lame, lame-libs, lame-devel, libmad, libmad-devel, ffmpeg y ffmpeg-devel
El procedimiento de instalación de software es, como root:
Herramientas para compilar
$ yum -y groupinstall "Development Tools"
$ yum -y install rpmdevtools
Dependencias para poder compilar sox según Fedora
$ yum-builddep -y sox
Librerías adicionales para la compilación (soporte mp3)
$ yum -y install lame lame-libs lame-devel
$ yum -y install libmad libmad-devel
$ yum -y install ffmpeg ffmpeg-devel
---- Construcción e Instalación del RPM ----
Ahora para reconstruir SoX con soporte mp3 el procedimiento como usuario regular es:
$ cd
$ rpmdev-setuptree (si no lo ha hecho antes)
$ yumdownloader --source sox (descarga los fuentes srpm)
$ rpmbuild --rebuild sox-14.3.0-1.fc13.src.rpm (compila/construye rpm)
$ cd rpmbuild/RPMS/x86_64
$ su
*contraseña*
# rpm -vhi --force sox-14.3.0-1.fc13.x86_64.rpm

NOTA: Procedimiento probado en F8, F9, F10, F11, F12 y F13, en el tiempo las versiones pueden cambiar, en el ejemplo se muestra la versión más reciente. Para versiones anteriores a F13, el compilado es para i586, a partir de F12 es i686. En el caso de x86_64, el compilado está en el directorio rpmbuild/RPMS/x86_64 .
Note la inclusión de mp3 y m4a en los formatos soportados. Ahora puede reproducir su mp3 o m4a desde la consola. Sox también permite convertir entre formatos y tiene muchas otras aplicaciones. Abajo reproduzco un mp3 de AC/DC.
---- Convertir mp3 ----
Otra aplicación común de sox es convertir de un formato a otro, por ejemplo de mp3 a cdr o wav, con cdr se está listo para quemar un CD Audio :)
$ sox -V Boinga.mp3 Boinga.cdr
sox: Detected file format type: mp3
sox: Input file Boinga.mp3: using sample rate 44100
size shorts, encoding MPEG audio (layer I, II or III), 2 channels
sox: Output file Boinga.cdr: using sample rate 44100
size shorts, encoding signed (2's complement), 2 channels
sox: Output file: comment "Processed by SoX"
Convirtamos ahora a un formato libre, ogg.
$ sox -V Boinga.mp3 Boinga.ogg
sox: Detected file format type: mp3
sox: Input file Boinga.mp3: using sample rate 44100
size shorts, encoding MPEG audio (layer I, II or III), 2 channels
sox: Output file Boinga.ogg: using sample rate 44100
size shorts, encoding Vorbis, 2 channels
sox: Output file: comment "Processed by SoX"
Veamos los tamaños resultantes solo por curiosidad incluyendo otros formatos sin ningún parámetro adicional al convertir, es decir, usando los valores por omisión.

[Guidelines Change] Changes to the Packaging Guidelines
by Tom Callaway
Here are the latest set of changes to the Fedora Packaging Guidelines:
---
The Emacs packaging guidelines were updated to handle cases where a
package's principal functionality does not require (X)Emacs, but the
package also includes some auxiliary Elisp files to provide support for
the package in (X)Emacs.
https://fedoraproject.org/wiki/Packaging:Emacs
---
The Scriptlet Snippets section dealing with the order that scriptlets
are invoked has been updated to include %trigger scripts.
https://fedoraproject.org/wiki/Packaging:ScriptletSnippets#Scriptlet_Orde...
---
A subsection was added to the Packaging Guidelines section on Filesystem
Layout in which it is made explicit that binaries in /bin or /sbin must
NOT depend on any libraries in /usr/lib or /usr/lib64.
https://fedoraproject.org/wiki/Packaging:Guidelines#Binaries_in_.2Fbin_an...
---
The section on Epochs was improved, and clarifying language about Epoch
use in Requires was added to the Packaging Guidelines.
https://fedoraproject.org/wiki/Packaging:Guidelines#Use_of_Epochs
https://fedoraproject.org/wiki/Packaging:Guidelines#Requires
---
New guidelines were added covering the packaging of Ada programs.
https://fedoraproject.org/wiki/Packaging:Ada
---
The section on Boostrapping in the Treatment of Bundled Libraries page
in the Packaging Guidelines has been amended to add the following:
Packages which are built in such a bootstrapping mode must not be tagged
for a final release (or pushed as an update for any stable release). FPC
will track the progress of approved bootstrapping exceptions via the
ticket requesting the bootstrap bundling exception.
https://fedoraproject.org/wiki/Packaging:Treatment_Of_Bundled_Libraries#B...
---
Macro forms of system executables (such as %{__rm}) should not be used
except when there is a need to allow the location of those executables
to be configurable.
https://fedoraproject.org/wiki/Packaging:Guidelines#Macros
---
These guidelines (and changes) were approved by the Fedora Packaging
Committee (FPC).
Many thanks to Hans Niedermann, Jonathan Underwood, Pavel Zhukov, and
all of the members of the FPC, for assisting in drafting, refining, and
passing these guidelines.
As a reminder: The Fedora Packaging Guidelines are living documents! If
you find something missing, incorrect, or in need of revision, you can
suggest a draft change. The procedure for this is documented here:
https://fedoraproject.org/wiki/Packaging/Committee#GuidelineChangeProcedure

Fedora accepted in to Google Summer of Code 2011!
by Ryan Rix
Heya folks :)
So... after a year's hiatus, Fedora's been accepted in to Google's Summer of
Code program for summer 2011!
If you're a university student looking for a job this summer, start thinking
about some awesome idea that you'd like to make happen in Fedora this
summer. Applications will open March 28, so start talking with developers in
IRC and mail, and find something awesome to do! We have a list of some ideas
at: http://fedoraproject.org/wiki/Summer_coding_ideas_for_2011 but don't
limit yourself to that list. Find a mentor, and make your idea happen!
Mentors should apply to be a mentor[1] in Google's Melange instance. be
inviting those who are listed on the Ideas page. We've still some work to do
before the student applications open, some scaffolding to build, and some
things to decide, so please join in. I'll be sending mentors more information
soon.
[1]: http://www.google-melange.com/gsoc/org/apply_mentor/google/gsoc2011 --
we're listed as The Fedora Project
Congratulations, everyone, for the Awesome we're doing!

--- Fedora Events ---
The purpose of event is to build a global Fedora events calendar, and to identify responsible Ambassadors for each event. The event page is laid out by quarter and by region. Please maintain the layout, as it is crucial for budget planning. Events can be added to this page whether or not they have an Ambassador owner. Events without an owner are not eligible for funding, but being listed allows any Ambassador to take ownership of the event and make it eligible for funding. In plain words, Fedora events are the exclusive and source of marketing, learning and meeting all the fellow community people around you. So, please mark your agenda with the following events to consider attending or volunteering near you!
---- Upcoming Events (Dec 2010 - Feb 2011) ----

--- First Look at Fedora 15 Alpha With Gnome Shell (thisweekinlinux.com) ---
Rahul Sundaram forwarded[1] an initial look at Fedora 15 Alpha's Gnome 3 Shell experience:
"After using this for a day or two at work, watching some of the upgrades that have happened, and showing it to coworkers, I have to say, I’m very pleased so far! Gnome 3 / Gnome Shell is really shaping up to be very useful, and the performance has significantly improved from the last time I used it."

--- Fedora 15 Alpha vorgestellt (Pro-Linux.de) ---
Henrik Heigl forwarded[1] an article from the German Pro-Linux.de blog on Fedora 15 Alpha:
"Fedora 15 "Lovelock" Alpha ist eine Vorschau auf die offizielle Version, die bereits alle geplanten Features von Fedora 15 enthält, aber noch nicht notwendigerweise in der endgültigen Form, und nur zum Testen eingesetzt werden sollte. Nach der Korrektur der meisten Fehler der Alphaversion soll am 12. April eine Betaversion veröffentlicht werden, die vom Code her vollständig sein soll.
Die Alphaversion kommt mit einer Vorschau auf GNOME 3 sowie den neuesten Versionen von KDE und Xfce. Das neue Init-System systemd wird standardmäßig eingesetzt. Systemd dient auch zur Sitzungsverwaltung. LibreOffice ersetzt OpenOffice.org. Für Unternehmen wurde das Buchhaltungs- und Inventarsystem Tryton hinzugenommen. Das neue Werkzeug BoxGrinder soll es leicht machen, virtuelle Maschinen für Plattformen wie KVM, Xen und Amazon EC2 aus einfachen Definitionsdateien zu erzeugen."

--- Test Days ---
Thursday 2011-03-10 was the second of three planned GNOME 3 Test Days[1]. Despite a reduced turnout, a lot of valuable testing took place thanks to the dedication of those who did show up, and many more bugs were discovered - some being fixed during the event. Vitezslav Humpa, who along with Radek Lat helped to organize this event, posted a recap [2] to the mailing list with a good overview of all the reported bugs.
Thus Thursday, 2011-03-17, will be preupgrade Test Day[3], where we will be testing this important mechanism for upgrading to Fedora 15. Upgrading is always one of the thorniest areas of a Fedora release, so if it's important to you and you can come along and help test, please do - the more testing we can get early on, the better the final result will be.
Next Thursday, 2011-03-24, is scheduled as power management Test Day[4], to test out various aspects of power management in Fedora 15. However, planning for the event is not yet complete, so it may be cancelled or postponed.

--- Test case management system comparison ---
Continuing her ongoing work on test case management system evaluation, Rui He posted a proposed list of features[1] that the candidate new system, Nitrate, must have before it can replace the current system of using the Wiki to organize test cases. After James Laska replied[2], the two continued to discuss and refine the list.

The first Beta blocker/nice-to-have review meeting took place on 2011-03-11[1], and the team worked through the full list of proposed Beta blocker and nice-to-have bugs. The first Beta test compose is due for release on 2011-03-22.

-- LATAM Fedora! --
LATAM Fedora is a regular column of Spanish language contributions around open source software. It is our first expansion into incorporating foreign language content into FWN.
This week's contribution is from Guillermo Gómez, a primer on Ruby Ping. Enjoy!
--- Ruby Ping ---
En paralelo con el tutorial de Ruby, que pronto verá su segundo capítulo, vamos en paralelo para publicaciones más frecuentes como FWN a escribir acerca del uso del lenguaje en otras tareas específicas, hoy nos ocupa algunas formas de hacer "ping" con Ruby.
---- Ping: librería estandar ----
Ping.pingecho utiliza TCP echo no ICMP echo para determinar si un máquina remota esta "viva". En realidad puede utilizar "otros" puertos, no necesariamente echo tcp/7.
1 irb(main):013:0> require 'ping' 2 => true 3 irb(main):012:0> Ping.pingecho('gomix.fedora-ve.org', 10) 4 => true 5 irb(main):016:0> Ping.pingecho('gomix.fedora-ve.org', 10, 'http' ) 6 => true
NOTA: si existe un paquete de rechazo ICMP al puerto especificado, se considera que la máquina está viva, es decir, "respondió con ICMP", así que no asuma que el puerto está abierto por el hecho de que Ping.pingecho le devuelva true.
---- net-ping ----
1. gem install net-ping
Fase común genérica para los siguientes ejemplos.
1 irb(main):001:0> require 'rubygems'
2 => true
3 irb(main):005:0> require 'net/ping'
4 => true
Ping UDP y TCP.
1 irb(main):011:0> host = "gomix.fedora-ve.org"
2 => "gomix.fedora-ve.org"
3 irb(main):012:0> u = Net::Ping::TCP.new(host)
4 => #<Net::Ping::TCP:0x7fb1cf3e16f0 @duration=nil, @timeout=5, @warning=nil, @exception=nil, @host="gomix.fedora-ve.org", @port=7>
5 irb(main):013:0> u.port = 80
6 => 80
7 irb(main):014:0> p u.ping?
8 true
9 => nil
10 >> u = Net::Ping::UDP.new(host)
11 => #<Net::Ping::UDP:0xb74b6a38 @duration=nil, @warning=nil, @data="ping", @timeout=5, @exception=nil, @bind_port=nil, @host="www.ruby-lang.org", @port=7, @bind_host=nil>
12 >> p u.ping?
13 false
NOTA: en este caso el rechazo tanto a nivel TCP como ICMP no es indicativo de que la "máquina" esté viva, es decir, aquí el PING es específico al servicio/puerto que se está probando, no a la máquina. Note en el último caso el ping-tcp al puerto 80 donde si hay respuesta porque hay un servidor web funcionando allí.
Ping ICMP con net-ping.
1 irb(main):011:0> host = "gomix.fedora-ve.org"

---- Fedora 16 Naming: Nominations are now open. Submit your suggestion! ----
Robyn Bergeron on Thu Mar 3 16:34:02 UTC 2011 announced[1]
"Hear ye, hear ye! Attention, all Fedora fans and release naming enthusiasts:
The time has come once again to choose the name for the next release of Fedora. Potential names will be accepted for consideration beginning March 3rd (in other words, NOW) through March 10.
[2]
Please note that you *must* follow the instructions and guidelines at the page listed above if you want your name to be considered. For instance, there must be an "is-a" link between the name Lovelock (from Fedora 15) and the name you suggest. That link must be different than previous links for Fedora release names. Also, we ask that you please conduct the required searches for brand and trademark names that might cause us problems.
Read the full guidelines at that page, where you can also find full schedule details for the release naming process.
For those of you interested in reviewing the history of Fedora release names, there is an appropriately named wiki page for doing so:
[3]
Be fun. Be creative. Help pick out an awesome name for Fedora 16! I am looking forward to your suggestions."

---- Announcing the release of Fedora 15 Alpha!! ----
Dennis Gilmore on Tue Mar 8 15:00:56 UTC 2011 announced[1],
"The Fedora 15 "Lovelock" Alpha release is available! This release offers a preview of some of the best free and open source technology currently under development. Catch a glimpse of the future:
[2]
----- What is the Alpha release? -----
The Alpha release contains all the beefy features of Fedora 15 in a form that anyone can help test. This testing, guided by the Fedora QA team, helps us target and identify bugs. When these bugs are fixed, we make a Beta release available. A Beta release is code-complete, and bears a very strong resemblance to the third and final release. The final release of Fedora 15 is due in May.
We need your help to make Fedora 15 the best release yet, so please take a moment of your time to download and try out the Alpha and make sure the things that are important to you are working. If you find a bug, please report it -- every bug you uncover is a chance to improve the experience for millions of Fedora users worldwide. Together, we can make Fedora a rock-solid distribution. (Read down to the end of the announcement for more information on how to help.)
-- Features
This release of Fedora includes a variety of features both over and under the hood that show off the power and flexibility of the advancing state of free software. Examples include:
* Updated Desktop Environments. Fedora 15 will ship with GNOME 3, the
next major version of the GNOME desktop. If you're interested in other experiences, KDE and Xfce will also be showcasing the latest and greatest in desktop technology from their respective projects.
* System and session management. Previously available as a technology
preview in F14, systemd makes its full-fledged debut in Fedora 15. systemd is a smarter, more efficient way of starting up and managing the background daemons relied on by services we all use every day - such as NetworkManager and PulseAudio.
* Cloud. Looking to create appliances for use in the Cloud? BoxGrinder
creates appliances (virtual machines) for various platforms (KVM, Xen, EC2) from simple plain text appliance definition files for various virtual platforms.
* Updated programming languages and tools. Fedora 15 features new
versions of Rails, OCaml, and Python. GDB and GCC have also been updated. (Fedora 15 was built with GCC 4.6.0, too!)
* Productivity Applications. LibreOffice is filled with tools for
everyday use, including word processing, spreadsheet, and presentation applications.
* Consistent Network Device Naming. Server management just got even
easier. Fedora 15 uses BIOS-provided, non-arbitrarily given names for network ports, taking the burden off of system administrators.
* Dynamic Firewall. Fedora 15 adds support for the optional firewall
daemon, that provides a dynamic firewall management with a D-Bus interface.
* eCryptfs in Authconfig. Fedora 15 brings in improved support for
eCryptfs, a stacked cryptographic filesystem for Linux. Starting with Fedora 15, authconfig can be used to automatically mount a private encrypted part of the home directory when a user logs in.
* DNSSEC for workstations. NetworkManager now uses the BIND nameserver
as a DNSSEC resolver. All received DNS responses are proved to be correct. If particular domain is signed and failed to validate then resolver returns SERFVAIL instead of invalidated response, which means something is wrong.
* Go Green. Power Management improvements include the PowerTOP tool,
which identifies the software components that make your computer use more energy than necessary while idle. Automatic tuning of power consumption and performance helps conserve on laptop battery usage, too!
* Business Management tools. Tryton is a three-tier high-level general
purpose application platform, providing solutions for accounting, invoicing, sale management, purchase management, analytic accounting, and inventory management.
* New Package Suite Groups. The Graphics suite group has been renamed
to the Design group, and the Robotics SIG has created the Robotics Package Suite, a collection of software that provides an out-of-the-box usable robotic simulation environment featuring a linear demo to introduce new users.
These and many other improvements provide a wide and solid base for future releases, further increasing the range of possibilities for developers and helping to maintain Fedora's position at the leading edge of free and open source technology.

---- Update on FUDCons in 2011 ----
Jared K. Smith, Fedora Project Leader on Wed Mar 9 18:53:00 UTC 2011 announced[1],
"I want to take this opportunity to bring your attention to a few important matters regarding FUDCon events in 2011.
Travel subsidy deadline for FUDCon Panama 2011 on March 14th
Planning is in full swing for FUDCon Panama in May, and it's time for the FUDCon planning team to begin evaluating subsidy requests. The deadline for the first round of travel subsidies is the end of the day (UTC time) on March 14th, and the FUDCon planning team will be meeting on March 15th to evaluate those requests. Any subsidy requests made after that time will be handled in a future subsidy meeting. I encourage anyone interested in attending FUDCon Panama and requiring travel assistance to refer to the instructions at [2] to learn about the subsidy process and open a Trac ticket with their details. We'll be giving priority to those travelers in Latin America who actively contribute to Fedora in meaningful ways.
Bids for FUDCon EMEA 2011 due March 15th.
I'm happy to see several bids starting to come in for FUDCon EMEA 2011. This is a reminder that any bids for FUDCon EMEA 2011 are due by the end of the day (UTC time) on March 15th. If you're interested in submitting a bid, please create a wiki page with the details and send an email to the fudcon-planning list letting us know about your bid. Refer to [3] for more details, or [4] for an example of a very thorough bid page.
Bids for FUDCon North America 2011/2012
I'd also like to formally open up bidding for FUDCon North America for the December 2011/January 2012 time frame. Bids will be due by the end of the day (UTC time) on April 8th. Again, please refer to [5] for more details.

---- ACTION REQUIRED: Important changes to Fedora translation workflow ----
Jared K. Smith on Thu Mar 3 15:46:28 UTC 2011 announced[1],
"Quick Summary -- - The Fedora translation workflow has changed. If you are a developer of a package being translated by the Fedora Translation (L10n) Project, you must change your workflow slightly if you want translated strings to appear in your software package. Tools and assistance are available to make this workflow as simple as possible for developers. Read below for details.
Details -- - Over the past couple of weeks, we've made some improvements and infrastructure changes to the Fedora translation system. We've moved from a self-hosted version 0.7 instance of the Transifex software to a hosted version of the 1.1-dev version at Transifex.net. The upgrade from version 0.7 to version 1.0 (and beyond) introduces a number of important changes for developers and packagers. Please pay close attention to this email, particularly if your software package uses translations provided by the Fedora Translation team. While the changes aren't terribly complicated, they do have a bigger impact on the developer than they do on the translation team.
The most visible change is that Transifex’s native integration with source code management systems has been replaced by a mechanism for automatic updates. Transifex now watches an HTTP view of a repository for change notifications. In addition, there is now a more secure command-line tool for project maintainers and translators. This new command-line tool has been packaged for Fedora in the "transifex-client" package. It is currently available in Rawhide (pre-F16), and in the "updates-testing" repositories for Fedora 13, 14, and 15, and EPEL 5 and 6.
Here's the new workflow:
This series of steps only needs to be run once for a project.
* The developer installs the "transifex-client" package:
yum -- enablerepo=updates-testing install transifex-client
* The developer runs the "tx init" command in the top level folder of
the project.
* The developer runs the "tx set" command according to the
transifex-client user guide found at
[2]. This creates a small config file, .tx/config, which can be committed in the repository for re-use, if desired.
This series of steps are run on as as-needed basis:
* The developer updates and commits his or her POT file to the
project's repository at string-freeze time or as needed.
* Transifex watches an HTTP link to that POT file and auto-updates its
English strings regularly, *OR* the developer can also push the POT file to Transifex (either manually or as part of a build script) by using the "tx push" command.
* Translators work inside Transifex. Translated strings are stored
inside of Transifex, and are *not* pushed automatically to the developer's repo.
* Before rolling a release, the developer runs 'tx pull' (either
manually or from a build script) to fetch the latest translation files from Transifex. Translation files do not need to live in the repo, although the developer may commit and store copies if desired.
For more details on the features of the new version of Transifex and more help on using the transifex client, please refer to either [3] or the Fedora-specific wiki page at [4]. If you have technical questions, feel free to ask questions in the #fedora-l10n or #transifex IRC channels or on the devel mailing list."

---- poppler soname bump in F15 and rawhide ----
Marek Kasik on Fri Mar 4 14:30:33 UTC 2011 announced[1],
"I plan to rebase poppler in Fedora 15 and rawhide to poppler-0.16.3. There is one API change (in PreScanOutputDev.h) and 1 soname bump (libpoppler.so.12 to libpoppler.so.13). You can test it against your package with this scratch-build: [2] I'll do chain-build of poppler and packages requiring it next Thursday (10th of March)."

--- Fedora Events ---
The purpose of event is to build a global Fedora events calendar, and to identify responsible Ambassadors for each event. The event page is laid out by quarter and by region. Please maintain the layout, as it is crucial for budget planning. Events can be added to this page whether or not they have an Ambassador owner. Events without an owner are not eligible for funding, but being listed allows any Ambassador to take ownership of the event and make it eligible for funding. In plain words, Fedora events are the exclusive and source of marketing, learning and meeting all the fellow community people around you. So, please mark your agenda with the following events to consider attending or volunteering near you!
---- Upcoming Events (Dec 2010 - Feb 2011) ----

--- Kororaa GNU/Linux is back (ITWire) ---
Rahul Sundaram forwarded[1] a posting about Kororaa GNU/Linux from Australia, but also what one user appreciates about Fedora:
"Always having been a bit of a distro-hopper, I went back to Debian, then to Ubuntu, but I was never happy. I have always been drawn to Fedora because of many reasons, but primarily their freedom drivers (promoting free culture and free software over proprietary solutions), but also because they stick to upstream and improve it there for the benefit of everyone, rather than doing their own thing.
Fedora is responsible for many of the great desktop enhancements we take for granted today, like AIGLX (Accelerated Indirect GLX), D-Bus, DeviceKit, HAL, NetworkManager, Ogg Theora, and PolicyKit."
The full article is available[2].
--- Linux Leaders, Part II: Fedora and Red Hat Derivative Distros (IT Management) ---
Rahul Sundaram forwarded[3] an article from the blog IT Management surveying the linux landscape and focusing on Red Hat-based distributions, including Fedora:
"In many of its releases, it is among the most innovative distros, releasing new software developed in co-operation with upstream projects. Development is more or less continuous within its Rawhide repository, with stable releases produced every six months.
The main derivative of Fedora is RHEL. RHEL is essentially a snapshot of Fedora, with extra testing for stability and quality control, and the addition of backports of some applications released by Fedora after the snapshot"

--- Alpha version of Fedora 15 released (H Online) ---
Rahul Sundaram forwarded[1] an article in The H Online about the Fedora 15 alpha release:
"an overview of which can be found in the release notes and feature list. The distribution will now use LibreOffice as its office suite – Fedora was one of the first distributions to make the switch to the OpenOffice.org alternative back in October last year. The alpha includes a Linux 2.6.38 release candidate as its kernel and uses a pre-release version of GCC 4.6. Responsibility for booting is taken up by Systemd, an alternative to SysVinit and Upstart. Systemd was in the running for use in both Fedora 14 and openSUSE 11.4, but was eventually dropped from both.
The most striking change in Lovelock and one which is sure to fuel plenty of discussion is the switch to GNOME 3, which breaks with many of the concepts that GNOME users, and computer users in general, have become used to over many years"

--- Fedora 15 Linux hits first alpha, debuts BoxGrinder for cloud (InternetNews.com) ---
Kara Schiltz forwarded[1] another article highlighting the Fedora 15 alpha release from the InternetNews.com blog:
"Fedora 15, codenamed 'Lovelock' now has its first alpha milestone available[2]. This is a BIG release for Fedora in that it's the first Fedora of the post Red Hat Enterprise Linux 6 era, and oh yeah first with GNOME 3, SystemD and BoxGrinder.
GNOME 3, including GNOME Shell mark the evolution of the Linux desktop and Fedora is likely to be the first big Linux distro to full integrate it. When it comes to systemd, that's been a long time coming, but in Fedora 15, it's finally fully baked making it easier and faster to manage and startup background daemons.
BoxGrinder is another story and is a very exciting technology. Red Hat first starting talking about BoxGrinder a year ago[3] as a new way to build virtual software appliances (think SUSE Studio from rival Novell)."

--- Debian takes security very seriously… but how? ---
Rahul Sundaram forwarded[1] a blog posting about Bugzilla security patches and linux distro comparisons vis-a-vis security:
"And people often come on IRC asking us for help, because their Bugzilla package provided with their Linux distro is broken or behaves in a weird way (typically a broken configuration or customization). And guess what? Most of the time, they use the Debian package. Yes, very seriously! For comparison, Fedora updated their Bugzilla packages the day after we released 3.6.4, and Mandriva the week after! It looks like they take security a bit more seriously."

--- Test Days ---
Thursday 2011-02-17 was Xfce 4.8[1] Test Day[2]. The event was well organized by the Xfce team, and a dedicated group of testers was able to expose some important bugs to be fixed.
The week of 2011-02-21 saw the traditional Graphics Test Week. Adam Williamson posted a full recap of the event to the mailing list[3]. He noted that participation was up again compared to the Fedora 14 events and that some important testing had been carried out, but also noted a worrying trend in status of bugs from previous events, with many bugs reported during the Fedora 13 and 14 events remaining unfixed. He promised to investigate the causes of this.
Last week and this Tuesday saw three Test Days under the internationalization and localization Test Week banner: the Anaconda i18n and l10n Test Day on 2011-03-01[4], the desktop i18n Test Day on 2011-03-03[5] and the desktop l10n Test Day on 2011-03-08[6]. These events were expertly organized and run by Igor Pires Soares, Rui He and Aman Alam, and were great successes with good turnouts and a lot of useful testing. Igor posted a recap[7] to the list, thanking all those who came to test.
Thursday 2011-03-10 is the second of three planned GNOME 3 Test Days[8], where we are continuing to work with the GNOME team to test GNOME 3.0 and its integration with Fedora 15 as rigorously as we can before the final release of both.
Next Thursday, 2011-03-17, will be preupgrade Test Day[9], where we will be testing this important mechanism for upgrading to Fedora 15. Upgrading is always one of the thorniest areas of a Fedora release, so if it's important to you and you can come along and help test, please do - the more testing we can get early on, the better the final result will be.

--- Official Fedora hosting of DeltaISO images ---
Andre Robatino has been building and hosting DeltaISO images for Fedora releases and pre-releases for some time now, assisting users with limited bandwidth to install and test Fedora. At the weekly meeting of 2011-03-07[1], it was announced that thanks to help from the Infrastructure team, from now on these images will be hosted within the Fedora project, making them much easier to access. They can now be found on the serverbeach1 site[2].

Reminder: today is GNOME 3 Test Day #2
by Adam Williamson
Hi, everyone! Just a quick reminder that today is the second Test Day
for GNOME 3:
https://fedoraproject.org/wiki/Test_Day:2011-03-10_GNOME3_Beta . Please
do come along and help with testing if you can. We're having trouble
with the 32-bit live image, but a 64-bit image is available now and all
the test instructions are in place. We'll be in #fedora-test-day on IRC
all day long to help out with testing, so come along and join us there.
Thanks a lot!

Updating SSL keys on fedoraproject.org 2011-03-10
by Stephen John Smoogen
Various SSL keys are aging out so we will be updating them before anyone
gets a <This CERT is not valid.> page.
We have already updated fedorahosted.org and will now be updating the
cert for the main site: fedoraproject.org.
The old certificate came from Equifax, was a 1024 bit key and had the
fingerprint:
SHA1 Fingerprint=E7:6D:26:72:D6:A2:2D:7A:5C:CF:BB:D2:05:B9:8E:7C:49:F5:F8:A8
The new certificate is issued by GeoTrust, Inc and is a 4096 bit key
with the fingerprint:
SHA1 Fingerprint=F6:D6:28:85:64:B1:11:19:38:2A:82:EF:F8:F0:22:E8:27:4F:A5:CF
Please report any problems with these certificates to
admin(a)fedoraproject.org
The change in certs will happen around 2011-03-10 20:00 UTC
