Para trocar alternar de diretorios rapidamente eu recomendo a utilizacao do comando pushd
Neste rapido exemplo, irei adicionar somente dois diretorios, mas podemos adicionar qnts quisermos.
$ [dougsland@medogz ~]$ pushd /tmp/
/tmp ~
$ [dougsland@medogz tmp]$
Certo, adicionamos o diretorio /tmp e agora vamos adicionar o diretorio /var
$ [dougsland@medogz ~]$ pushd /var/
/var /tmp ~
$ [dougsland@medogz var]$
Agora para ficar alternando entre os diretorios e' so' digitar pushd
[dougsland@medogz var]$ pushd
/tmp /var ~
[dougsland@medogz tmp]$ pushd
/var /tmp ~
[dougsland@medogz var]$
Para listar os diretorios que estao na lista?
[dougsland@medogz var]$ dirs
/var /tmp ~
Para remover da lista?
[dougsland@medogz var]$ popd
/tmp ~

vi /etc/libvirt/libvirtd.conf
Add these lines (or just uncomment):
-----------------------------------------------
# Logging level: 0 none, 4 errors, 3 warnings, 2 informations, 1 debug
# basically 1 will log everything possible
log_level = 4
To show logs through a file (/var/log/libvirt/libvirtd.log)
---------------------------------------------------------------
# Logging outputs:
# An output is one of the places to save logging informations
# The format for an output can be:
# x:stderr
# output goes to stderr
# x:syslog:name
# use syslog for the output and use the given name as the ident
# x:file:file_path
# output to a file, with the given filepath
# In all case the x prefix is the minimal level, acting as a filter
# 0: everything
# 1: DEBUG
# 2: INFO
# 3: WARNING
# 4: ERROR
#
# Multiple output can be defined , they just need to be separated by spaces.
# e.g.:
log_outputs="1:file:/var/log/libvirt/libvirtd.log"
For filters use:
-----------------------
# Logging filters:
# A filter allows to select a different logging level for a given category
# of logs
# The format for a filter is:
# x:name
# where name is a match string e.g. remote or qemu
# the x prefix is the minimal level where matching messages should be logged
# 1: DEBUG
# 2: INFO
# 3: WARNING
# 4: ERROR
#
# Multiple filter can be defined in a single @filters, they just need to be
# separated by spaces.
#
# e.g:
# log_filters="3:remote 4:event"
# to only get warning or errors from the remote layer and only errors from
# the event layer.
To finish, just restart libvirt:
$ /etc/init.d/libvirtd restart

Hello,
I would like to give my many thanks to Jordi Sayol for his donation of an radio Guillemot Maxi Radio FM 2000 PCI radio card device to me.
I am really happy to receive this device, thank you Jordi Sayol!
Also, it's working like a charm on Linux!
Cheers,

Debian
Redesigning Communication
Comments about the ideas of a better "looking"
It seems to be a "hot topic" week for Debian, yesterday the announcement of Time Based Freeze Cycles and today the proposal to redesign some parts of Debian. No matter how orthogonal those topics are, communication seems to be needing real improvements inside Debian Project, but I will leave this item for later (and I mean communications amongst teams and developers, nothing related to the Press Team).Yes... long time since I last post. Apparently, I will be able to graduate by April of 2010, but that remains for another post.
First of all, let me state this perfectly clear: I believe Agnieszka (pixelgirl) did an incredible job with her redesign proposal. As a concept. (Or proof of concept). That's why I share some of Rhonda's concerns.
I don't think anybody disagrees that several parts of the Debian project urges improvements in the design field, some of them requires a total redesign, that doesn't mean we need a new logo. It is curious to see how some things happen in a strange related fashion, no matter if you believe in $DEITY (superior power or destiny), life has its ways. Early this week, the new logo of Pepsi was announced and some comparison images were created to show the evolution of Pepsi and Coca-Cola logos. It's possible to find quite a few articles commenting about the new logo, about brand, market share and strangely related to a "new logo proposal".
Yes, I like Debian's logo, it has a strong recognition, I don't think we need to change it and I don't have reasons to believe we need a new one.
The Swirl can be applied vertically and horizontally, it can also be applied alone without the "debian" text and for those wondered about the details of our logo and font, a quick (re)search would review the DebianLogo wiki page, with a lot of details.
That being said, the art work concept is indeed an important first step, but it is certainly not the only one. As I said, life has its ways, yesterday, Rhonda mentioned the amazing work of Kalle Söderman, who has looking for the Debian's Global Picture since 2007 and who did move to the step after the mockups having real instances implemented maintaining part of Debian WWW Team informed and working on feedback and smooth integration.
No matter what people said (or will say), CSS can't do all the magic.
Kalle deserves a big Thank You for his work and, IMNSHO, should be the first option to be considered in a merge (that's why you shouldn't resign Rhonda, you got quite some work to do to get it integrated).
The point, is that Kalle is not alone. There are a lot of people behind Debian Art and it would be great to see a joint effort from all artists interested in helping Debian to have a better unified look-and-feel on the Debian Project, not only on our web interfaces, but also on our products: CDs/DVDs (and its covers), desktops, wallpapers, boot loaders, splash screens, documentations, business cards, banners, t-shirts (and a bunch of other materials). It is not just a matter of writing something completely new without keep in touch with an already existent community, it is also the need to communicate and push such goals project-wide, so we can have massive adoption.
I was surprised by the fact that a lot of people mixed quite a few orthogonal points. Specially the fact that the website also needs some work in the Information Architecture field in order to improve the users' experience, but that's one point of a project-wide concern (that Kalle took into account).
Finally, some may not remember that we vote (General Resolution) to choose our logo, back in 1999 (10 years ago).
Yes, we need to do better on communicating and we need do to better with our design (and probably Marketing), but please do not start such work by changing our logo.

Disponível no site http://videos.tchelinux.org a palestra Por que
usar Software Livre? Ministrada por Leonardo Vaz em Bagé na Urcamp
Code Rush is a 1998 documentary following the lives of a group of Netscape engineers in Silicon Valley. It was shot during a time of flagging company fortunes, the initial release of the Mozilla code as an open source project, and the friction of an impending AOL-Netscape merger. The documentary depicts Netscape programmers forgoing their normal lives and families in an attempt to save the company from ruin.

Olá,
Saiu uma nota no site Br-Linux sobre os vídeos que o grupo Tchelinux vem disponibilizando na internet. Gostaria de agradecer a todos os palestrantes que colaboraram p/ este acontecimento... :)

"E a persistente turma do Tchelinux continua dando o exemplo de não apenas realizar seus eventos descentralizados e sem aquele foco em pregar para os já convertidos, como ainda se esforçar para que o conteúdo apresentado chegue a todos os interessados que não têm como estar presentes aos seus eventos nas terras gaúchas."
