Last week brought an early holiday present to many open source enthusiasts and technology consumers with the release of Fedora 12. Every six months the anticipation builds as I look forward to taking the latest version of Fedora for a test drive and trying out all of the new features and enhancements. After just a few days with Fedora 12 I’m already impressed with the feature set and polish in this release.

I’ve installed Fedora 12 on one of my laptops and also on a Dell mini netbook. First off, I really like the artwork in Fedora 12 and the new theme with the rays of light looks great. The Fedora Design Team continues to impress me with the new graphics and imagery they create for each release. Beyond that, everything just feels better and more comfortable, and the extra attention to detail all around the desktop really pays off.

I installed Fedora 12 from a USB key and the process was flawless and the fastest I’ve experienced yet with Fedora. The boot time was also very quick – even on my netbook. I’m excited to see Fedora’s support for the Moblin Core desktop environment in Fedora 12. This is my first experience with Moblin and I’m looking forward to putting in more time to test it out. Fedora continues to show the flexibility and functionality of free software and its impressive coverage of mini systems and netbooks with the inclusion of Moblin in Fedora 12.

Another feature in Fedora 12 that I’m happy to see is the improved webcam support. My webcam just works with Fedora 12.

Fedora 12 also includes several new virtualization features such as libguestfs that I look forward to trying out.

Red Hat’s software development model relies on its active sponsorship of leading open source projects including Fedora. This model enables Red Hat to deliver superior technology, faster, and with resulting products that are better suited to customer requirements. I thank the Fedora community for its continued hard work and congratulate them on yet another solid release. I encourage everyone to download Fedora 12 today and take it for a spin: http://fedoraproject.org/get-fedora.

In part 1 I discussed how these days Linux Live CDs usually come with a prebuilt disk image of the distro which is simply copied over to the hard disk during installation. (The “old” method was to rpm/dpkg-install the packages which is much more time-consuming). However my first test wasn’t very successful because I was using the “cp” command to copy files.

Anaconda (the Fedora installer) is smarter than this. It “dd”s the prebuilt disk image to the hard disk and then uses an ext2/3/4 utility called resize2fs to expand it to the correct size.

I changed the previous guestfish script to take this approach.

The new/Anaconda approach is much faster. Our total time is down from over 18 minutes to 2½ minutes (approximately 2 minutes for the “dd”, 2 seconds for the resize2fs, and the rest of the time taken doing the partitioning and LVM creation).

Unfortunately we have to leave Ubuntu behind at this point. Ubuntu ships with a squashfs, and I’m not aware of any way to turn this into an ext3 partition efficiently (except to use “cp” which we showed in part 1 was very slow). The new script only works with Fedora Live CD ISOs.

The new script is after the cut.

#!/bin/bash -

function usage ()
{
    echo "virt-prebuilt.sh live.iso disk.img size"
    echo "  where 'live.iso' is a Fedora Live ISO"
    echo "        'disk.img' is the target disk image"
    echo "        'size' is the target size in Gigabytes"
    exit 1
}

if [ $# -ne 3 ]; then
    usage
fi

# Work out size of target LV.
target_boot_mb=200
target_lv_mb=$(($3 * 1024 - $target_boot_mb - 128))

# Run guestfish.
time \
guestfish -x -a "$1" <<EOF
# The source ISO will be /dev/sda.  The target drive will be /dev/sdb.
alloc "$2" "$3G"
run

# Get to the packed ext3 filesystem.
mkmountpoint /t
mount-ro /dev/sda /t
mkmountpoint /tt
mount-loop /t/LiveOS/squashfs.img /tt

# Make a separate /boot partition on the target disk.
sfdiskM /dev/sdb ",$target_boot_mb ,"
mkfs ext3 /dev/sdb1

# Make the root LV.
pvcreate /dev/sdb2
vgcreate vg_live /dev/sdb2
lvcreate lv_live vg_live $target_lv_mb

# Copy the packed filesystem to the root LV and resize.
time dd /tt/LiveOS/ext3fs.img /dev/vg_live/lv_live
time resize2fs /dev/vg_live/lv_live

# Mount the root filesystem and copy /boot to /dev/sdb1
mkmountpoint /root
mount /dev/vg_live/lv_live /root
mkmountpoint /boot
mount /dev/sdb1 /boot
glob cp-a /root/boot/* /boot
df-h

# Unmount everything and exit.
unmount /root
unmount /boot
unmount /tt
unmount /t

echo Done.
EOF

Anaconda doesn’t just do a straight copy, it also does a whole lot of munging of the filesystem afterwards, including replacing /etc/fstab and rebuilding the initramfs. The script above avoids that so you can only boot it in qemu using an external -kernel and -initrd.

I think this technique is promising. It certainly sounds wonderful to “stamp out” new distro installs in a minute or two. But …

1. Distributions would all have to start shipping filesystem images.
2. Distro-specific munging would have to be kept to an absolute minimum.
3. Get rid of initramfs’s that contain hard-coded details about the specific platform on which they boot (a very good idea in general IMHO).

In part 3 I’m going to compare how this approach compares to others: virt-install, manual installation, kickstart, cobbler, debootstrap and ubuntu-vm-builder.

Previously I took a look at unpacking Fedora and Ubuntu live CDs to find out what’s inside them and to ask the question can we use the prebuilt filesystem image that these live CDs contain to quickly create a Fedora or Ubuntu “all-defaults” virtual machine?

This is my first attempt, and it’s not successful, but it does demonstrate a large and interesting guestfish script doing a non-trivial amount of work.

This script:

1. mounts the prebuilt filesystem from either a Fedora or Ubuntu live CD
2. creates a disk image with a 200 MB /boot partition and a single / (root) logical volume covering the remainder of the disk
3. uses the cp -a command to recursively copy the prebuilt filesystem to the disk

Where it fails is that “cp” isn’t very fast. On my local machine it took 18 minutes to copy all the files across, which means this isn’t a practical “instant install” method. (I didn’t in the end try to boot the final disk image).

In part 2 this week, I’ll look at the approach that anaconda takes: It dd’s the disk image and then runs resize2fs on it to expand it into the available space.

In part 3 I’ll compare this approach to others: virt-install, manual installation, kickstart, cobbler, debootstrap and ubuntu-vm-builder.

The script itself follows after the cut:

#!/bin/bash -

function usage ()
{
    echo "virt-prebuilt.sh live.iso disk.img size"
    echo "  where 'live.iso' is a Fedora or Ubuntu Live ISO"
    echo "        'disk.img' is the target disk image"
    echo "        'size' is the target size in Gigabytes"
    exit 1
}

if [ $# -lt 3 ]; then

えー、Fedora12がリリースされたということでさっそくインストールしてみました。
今回インストールしたマシンの構成は以下の通り。

で、まずLiveUSBで起動しようとしたら失敗。どうもログイン画面の直前でフリーズしてしまうらしい。
LiveUSBがKDEだから悪いのだろうか、とか色々と考えて試してはみたもののにっちもさっちも。

しゃーないのでNetinstCDでもってインストールを試みることに。
こちらの起動メニューは通常のブートとベーシックなビデオドライバでのブートがあったのですが、ベーシックなビデオドライバでないと起動できませんでした。どうもビデオドライバの問題ということみたいですね。

で、そこから先は何もトラブルなくインストール完了。Fedoraの割にノントラブルとかちょっと拍子抜けするなーなんて思わなくもない。

で、起動後に適当にパッケージを追加して適当に設定。今回は初めてAMD系のビデオドライバとしたのですが、オープンソースのドライバだと3D機能が有効にできない。開発中というradeonhdを試してみるもダメ。まぁちゃんとradeonhdになっているかはよく分かってないのですが＾＾；

ただ、radeonhdのドライバを使おうと使うまいと、サウンドはHDMI経由から出せるようです。デフォルトがそうなっててちょっとビックリ。サウンドは192kHzで出せるとかマニュアルに書いてあった気もしたんですが、PulseAudioで試したところ96kHzが限度でした。いやまぁ96kHzで十分だけどさ。

旧PCからのデータも移行できましたし、radeonドライバでもデュアルディスプレイにはなっているので実用上問題はありません。Compizが使えないのが悲しいですが、それは今後のドライバの進化を楽しみにしておくとしましょう。

プロプライエタリなドライバもあるようですが、そちらはまだ対応できてないようです。nVidiaの方はどうなっているか知りませんが、AMDが遅いのはいつものことらしいので気長に待ちますかね。

旧PCから引き継げていないものとして、Postfixの設定があります。この設定をどうも間違っているらしく、プロセスが立ち上がらない…。
エラーメッセージもでないので正直困ってます。後からじっくり調べてみよう。こいつがなくてもさして困りはしないけどさ…w

ということで、クァッドコアを満喫しております。Firefox使っていても処理が重くならないのがいいですね。
また、メモリはやっぱり4GB積んでいようとほぼフルで使いきろうとするんですね（笑）　ディスクキャッシュが大半ですが、どんだけディスクキャッシュに喰うんだよと。面白いもんです。

あとはCompizだけだなー。ドライバ開発ガンバレ！

Ok, a ver: Todos sabemos que es messenger, sabemos que es una plataforma de comunicacion basada en .Net Framework de Microsoft (Compañia que odio y desprecio), y que esta instalado por default en cada pinche sistema que Microsoft lanza y que gracias a esto la gente cree que messenger es el unico programa de IM existente o bien, cree que es el mejor programa de IM que se puede encontrar en la web. Pues bueno eso es falso. Pra empezar toda tecnologia de Microsoft es mediocre, si es mediocre es inestable y que es un app inestable? NADA. Pero este post no se enfoca al protocolo del app ni al messenger en si, ni mucho menos en este famoso winsocket que todos los amiguitos y fiel seguidores de Gates usan para decir : “uy VB es la hostia! Logre programar mi propio msn en menos de 300 lineas!”

El post se enfoca en declarar a msn como La aplicacion mas hipocrita de todas. Y esto por que? Bueno estimado lector o lectora, aca es cuando le pregunto amablemente: Tiene usted vida social? Si la repuesta es si, dudo mucho que usd comprenda mis fundamentos para redactar esta entrada del blog, pero si la respuesta es no y es usd un geek que se desvela por programar por placer en lenguajes que valen la pena o bien jugando con el kernel amado de linux entonces es posible que me entienda. No tengo vida social por estar en mi cuarto mas de 12 horas por dia escribiendo codigo, y esto a que tiene que ver con msn? Simple, que a pesar de  estar solo uso el msn o al menos su protocolo ya que como uso linux utilizo clones como aMSN o emesene (Que a pesar de ser clones resultan ser mejores que el msn original), y ustedes se diran: Pero todo mundo usa msn, bueno creanme no todo el mundo opta por esta basura pero yo lo tengo que hacer por que a noob que ayudo a noob que agrego. En la universidad he ayudado a muchos noobs: Konata, la amiga de Konata, el amigo de Konata y emm.. al otro amigo de Konata que al final resulto ser un lammer y le dije RTFM!!!! Y a todos ellos los he agregado al msn, la pregunta es les hablo? No. Por que? Por 2 razones:

1- Se que solo me agregan por mis skills, para que les aclare dudas etc.

2- No me caen bien, lol, si leen esto ni me vuelven a hablar jeje.

En fin, por otra parte cuando hay alguien que me cae bien y se conecta pues le hablo, y que pasa? PUFF! Fulano se ha desconectado. Ok… Supongo que eso quiere decir “Te vas al carajo no quiero hablar” Bueno, y despues a uno le preguntan que por que es tan amargado o por que trata tan mal a los demas noobs e ignorantes de la facultad, pero bueh… Otro punto: Los bloqueos, me bloqueaste? No me importa, y si me pregutas por que lo hice pues usualmente invento una excusa tonta… No creen que esa excusa es mas que innecesaria? Deberian de decir “Te bloquie por que no te soporto, me caes mal y eres horrible” MMM… Eso se aplica a mi. Bueno, no hubo mucha informatica en este post, mis disculpas por ello pero era para desahogarme.

Gracias por su tiempo.

Well, most of my college department labs run on Fedora but they are passionate followers of the “If it ain’t broken, don’t fix it” school of thought. They’re still using Fedora Core 5, which feels like eons ago. I myself started using Fedora from the last core version, 6. I was wondering whether they would upgrade any of those labs, which are all now unsupported, of course! I’ve spoken to the person managing one of the labs, and he told that it’d be nice to upgrade if there were no issues.

So, after I’m done with my end semester exams, I’m gonna go try and convince the lab in-charge to install Fedora 12 before students start using the lab for the next semester. Hopefully there won’t be any compatibility issues now. These days, all the problems are with proprietary OSes. I once tried to install the latest version of one, but had to spend the better part of a day searching for drivers. So I just kicked that out of my PC, and it is pure once more.

I’d need to explain him the need to update it asap due to what is a vulnerability on publicly accessible computers: The unrooted installation permission.

And having exams wrapped around the release day sucks, I’ve just downloaded the 32 bit and about to complete the 64-bit DVD. My desktop has been running Fedora 12 since the beta versions, and has never had a problem.

I hope to go one step forward, and start using the SSN-CTS open source lab for something useful to the community. There’s a long way to go, but these first steps are what count,

If you got Fedora 12 , own a NVIDIA Video Card, and need 3D, you probably getting insane by now to make that Driver work. Fear not! I found a solution and would like to share with the community:

Install the RPM Fusion Repositories, if you didn’t already.

su -

mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img

dracut /boot/initramfs-$(uname -r).img $(uname -r)

gedit /etc/grub.conf

Add the following to the end of the line(s) starting with ‘kernel’:

dblacklist=nouveau

Now:

setsebool -P allow_execstack on

yum –enablerepo=rpmfusion-nonfree-updates-testing install kmod-nvidia

nvidia-xconfig

Reboot.

There you go

Często bywa tak,że chcemy zainstalować drukarkę HP pod Linuksem i nie mamy do niej sterowników. Na szczęście HP wynalazło sprytne oprogramowanie dla Linuksa. Nazywa się hplip. No to do dzieła.
1. Ściągamy ze strony HP najnowszy hplip

2. Hplip instalujemy za pomoca konsoli wywolując jako zwykły uzytkownik

$ sh hplip-3.9.10.run

3. Wykonujemy polecenia i hplip instaluje się automatycznie

Druga metoda.  Wykonujemy plik hplip-3.9.10.run manualnie.

1. Do tego celu posłuży nam instrukcja jaką znajdziemy na stronie producenta.

2. Aby zainstalować naszą drukarkę najlepiej skorzystać nie z samego programu HP lecz wybierając z przeglądarki http://localhost:631.

3. Instalujemy naszą drukarkę, która powinna znaleźć się na liście.

Po instalcji nasza drukarka gotowa jest do pracy.

Lots of virt developers, including me, were interviewed for the Fedora 12 release by Mel Chua.

O Febootstrap é uma ferramenta que cria um sistema Linux baseado no Fedora dentro de uma pasta. Ele pode ser usado para criar um sistema totalmente funcional. Ele pode ser baixado no site: http://people.redhat.com/~rjones/febootstrap/ ou nos repositórios de sua distro. As distros baseadas no Debian podem usar o Debootstrap.

Para usá-lo, digite “febootstrap fedora-versao pasta “, onde “versao” é a versão do Fedora a ser instalada e pasta o nome da nova pasta para criar o sistema.

==================================================================

There were two topics on the agenda as posted on the mailing list:
- F12 release events
- Tamil team
- During the course of the meeting, we decided to discuss the issue of
“people becoming Fedora Ambassadors and not carrying out their duties as
required” also.

Minutes -
Release events:

- Planned at MIT Manipal, early January (Ankur Sinha)
- Release party, install fests at Bikaner (Jaideep)
- Plans to migrate 100 desktops of Coal India to fedora12 (Pradipta)

Tamil team discussion:
Postponed (next meeting?)

Discussion over fedora ambassadorship

- Making sure that blogs of *every* Ambassador is on
planet.fedoraproject.org

- some sort of system to prevent people from signing up (because its
ultra cool) and then not working.
- make a nice proposal and send it for discussion and whatever be the
result send it to FEMSco for approval
- ideas, such as an Ambassador should be participating in at least one
Fedora subgroup (ie docs/packaging/design/websites…)

- Mentoring to make sure newbies holding release fests know what to say
ie – *correct content* (since they’re short on experience, we don’t want
them saying stuff that is different from the community’s working etc.)
- Setting up a wiki page and supplying people with updated slides and
material to be used at release fests.

- collecting feedback after a Fedora event from the audience (ideas
needed on how to go about doing this).

- regular IRC meets : fortnightly *at least*

- good install fests never turning into sustained activities : why??

==========================================================================

These are only ideas in short. Please go through the meeting logs
provided above.

There’s quite a lot of work to be done.

- I’m in-charge of rounding up all “FAs from India”’s blogs and making
sure they’re on the planet.
- Slides etc? (any hands ??)

There are also agendas that still need more discussion. Future meets or
discussions on the mailing list are needed.

Thank you all for attending

Have a nice evening

regards,
Ankur

PS Also forwarding the the ambassadors list.

Gray fedora worn by Jack Ruby when he shot Lee Harvey Oswald sold for $53,775 at auction….. another relic that should be in a museum!

No se que demonios le ven a ese Google Chrome O.S., uno entra a Youtube y lo primero que ve es un thumbnail relacionado al sistema este, es algo logico ya que Google esta detras de Youtube despues de todo pero la verdad es que me cansa ver tantos posts en blogs y foros refiriendose a lo magnifico que va a ser. Personalmente pienso que no deberia de causar tanto revuelo en la gente que usa linux ya que no es mas que otra distribucion, y bueno, no tendria mucho sentido decir que Canonical esta asustada por esta nueva linea de Google ya que la misma compañia solicito su apoyo para desarrollar el sistema. Aunque pensandolo bien… Pueden llevarse bien hoy, pero mañana el panorama puede cambiar.

Estoy trabajando en un proyecto que involucra la personalizacion de un live-cd, uso el kernel de Debian para ello ya que hablamos de Debian Sid pero quiero pensar que Google tiene su propio nucleo corriendo, o acaso nos encontraremos con un segundo ubuntu? Digo, no tendria nada de malo, mas bien gente optaria por probar chrome O.S. si se basara en ubuntu pero definitivamente seria muy interesante ver si google en verdad esta aportando algo nuevo a linux, desde cero.

Bueno ya me canse, para terminar con esto, el revuelo de google, innecesario totalmente.

Previously I’ve shown you can use guestfish to unpack a Fedora live CD.

I’m interested in whether we can use the contents of these live CDs to mass-install operating systems using libguestfs.

If you imagine that you go through an “all defaults” install of say Fedora or Ubuntu to a new virtual machine, then when you end up with is an identical disk image containing 1-2 GB of default packages and a lot of empty space. Two people asked to go through the same all-defaults install of the same distro would end up with roughly the same content. The details on the disk would be slightly different because some parts of the disk partitioning and ext3 superblocks change slightly depending on the overall disk size. But really those things can be fixed up afterwards using a little repartitioning, lvresize and resize2fs.

Let’s look inside an Ubuntu live CD:

$ guestfish --ro -a ubuntu-9.10-desktop-amd64.iso

Welcome to guestfish, the libguestfs filesystem interactive shell for
editing virtual machine filesystems.

Type: 'help' for help with commands
      'quit' to quit the shell

><fs> mount-loop /t1/casper/filesystem.squashfs /t2
><fs> cat /t2/etc/debian_version
squeeze/sid

The file /casper/filesystem.squashfs seems to be a complete Ubuntu installation, and if I’m understanding this correctly the Ubuntu installer will copy this to the newly created filesystem directly. That will be the new Ubuntu installation, plus or minus some config file changes and some extra packages downloaded afterwards from the net.

Here’s the same examination of the Fedora 12 Live CD:

$ guestfish --ro -a Fedora-12-x86_64-Live.iso

Fedora release 12 (Constantine)

Again I hope I assume correctly that the installer copies ext3fs.img to the hard disk when installing Fedora 12.

So my vague plan, assuming anything I’ve written above is correct, is to take these pre-made filesystem images and allow people to quickly install specific operating system images from a simple tool:

$ virt-press Fedora-12 F12

which would stamp out a Fedora 12 VM in a few seconds and register it with libvirt as “F12″.

I’m not sure this is possible yet …

For more half-baked ideas, see my ideas tag.

I’ll mention first that this isn’t my idea, and it’s not new or original. OLPC already implemented a View Source button.

Why can’t we have the same for Fedora? This is how it would work …

The View Source button would hover in your task bar. When pressed it opens up this dialog:

Like xkill and xwininfo, pressing the “point at a window” button changes your mouse so you click on the program you want to view the source of. X sort of makes it possible to find out (with a bit of effort) which binary is behind each program (see for example the xprop command).

You do an rpm -qf on this binary (or use a yum search) to locate the source.

Use yumdownloader --source to download the source. Unpack it into a standard rpmbuild location, and open up the user’s preferred editor.

With experience, and many custom rules and heuristics, you can extend this idea. For example, if they pointed at a dialog box, search the source for strings from the dialog box to try to locate the exact lines of code.

Or have some debuginfo-like metadata packages which are generated when packages are built, to allow very precise file/line locations to be determined.

Combine the whole thing with LXR so we can browse source intuitively.

This is a great way to encourage contributions to Fedora and Free software in general, because I think it would really make code much more accessible to casual programmers, tinkerers and children. Even experienced programmers would find it useful when tracking down bugs in random applications.

Es sind aufregende Worte Monate für Freunde Enthusiasten von und für Betriebssysteme aller Couleur. Schließlich hat alles, was Rang und Namen hat, eine neue Version des eigenen Betriebssystems herausgebracht. Canonical hat Ubuntu 9.10 „Karmic Koala“ veröffentlicht, Novell openSUSE 11.2 , Red Hat Fedora 12 „Constantine“ und der Monopolist Windows 7. Was? Windows 7? Ja, Windows 7.

Der Leitwolf

Schließlich haben die Redmonder diese neue Version für eigene Verhältnisse ziemlich zügig auf den Markt gebracht. Und es ist ein offenes Geheimnis, dass Windows 7 die bessere Version des Vorgängers Vista ist und keine Neuentwicklung. Spötter behaupten gar, 7 sei nur das neueste Service Pack für Vista. Aber warum so schnell? Ja, schon fast hastig? Nun , die Konkurrenz, die Jungwölfe, spürte, dass der Leitwolf schwächelt. Und wie junge Wölfe, allen voran Canonical und Google, so sind, fordern sie das Alphatier beim kleinsten Anzeichen von Schwäche (lies: Vista) heraus.

ChromeOS

Der Jüngste unter den Herausforderern ist Google, im Usenet liebevoll „die allwissende Müllhalde“ genannt.

Googles neues System ist gerade erschienen. Es muss etwas an Besonderes an ChromeOS, in Analogie zum Chrome Browser, sein, denn die sog. Blogosphäre schreibt sich die Finger wund und das Internet quillt über vor Gerüchten und echten Informationen. Zwei Dinge sind es hauptsächlich:
1. Es ist das Betriebssystem von Google. Und die allwissende Müllhalde ist wahrscheinlich die, dem Endverbraucher, bekannteste Softwarefirma. Nachdem dem Redmonder, versteht sich. Und da greift die alt bekannte Kundenlogik: bekannte (und erfolgreiche) Firma = gutes Produkt. Alleine dieser Punkt dürfte Google einen guten Marketingbonus geben. In Kombination mit gescheiter PR vielleicht sogar den einen oder anderen Prozentpunkt Marktanteil.
Natürlich kann die allwissende Müllhalde nicht ein 08/15 Betriebssystem veröffentlichen. Nein, es muss, und das ist der zweite Punkt, etwas neues sein, etwas innovatives. Und das Unternehmen hat ein Problem: So ein Betriebssystem braucht auch Software, die man benutzen kann. Google hat solche Software, allerdings nur online. Nun folgt der eigentliche Trick: Man macht aus der Not eine Tugend. In dem man den hauseigenen Browser Chrome zum Kernstück des Systems gemacht wird, sind die vielen Online-Anwendungen für die Benutzer verfügbar. Und wenn die Müllhalde es schafft, den Benutzer klar zumachen, dass Online-Anwendungen ein Vorteil und kein Nachteil sind, dann stehen die Chancen gut, nennenswerte Marktanteile Bill Gates’ ehemaligen Garagenunternehmen ab zuknöpfen. Zumindest der Zeitpunkt scheint günstig: Selten waren die Benutzer eher bereit das Betriebssystem zu wechseln.

Sin dudas, Linux está ganando terreno exponencialmente. Cada vez más usuarios de Pc están migrando a este sistema Libre y en muchos casos Gratuito.

Hoy les traigo una página, perteneciente a una comunidad Linux en crecimiento (comenzaron en abril bajo el nombre Linuxinga!, éramos 17 usuarios cuando me registré, hoy somos más de 200).

Puede que la arquitectura recuerde a T! (en su época linda, antes de aburguesarse y bastardear a la comunidad), pero la diferencia es que se puede postear dudas y consultas. Es una comunidad muy abierta y siempre dispuesta a ayudar y compartir.
