			<content:encoded><![CDATA[<p style="text-align:justify;">In this tutorial I will show you how to install the <a href="http://emacs.orebokech.com/">Emacs-snapshot</a> at your <a href="http://www.debian.org">Debian</a>. <a href="http://emacs.orebokech.com/">Emacs-snapshot</a> is a cool package built and deployed by <a href="http://www.orebokech.com/">Romain Francoise</a>, a long time GNU and Debian developer. Romain is doing a great job packaging emacs from CVS for those interesting in run a really fresh emacs (with the last feature), even more fresh then the packages at Debian official repository. Due to the fact that Emacs is one of the most old editor still in development, install a CVS snapshot doesn&#8217;t means &#8220;install unstable and with bugs&#8221; version. In my tests here the package works smoothly without giving me any problem, but remember: Install it is up to you<em> </em> <img src='http://s1.wp.com/wp-includes/images/smilies/icon_wink.gif' alt=';-)' class='wp-smiley' /> </p>
<p style="text-align:justify;">This post is dedicate to my good friend <a href="http://www.dirceu.info">Dirceu</a>, that <a href="http://www.dirceu.info/blog/usando-emacs.html">recently</a> instigate me to give Emacs a try. It is not easy for a long time <a href="http://www.vim.org">vim</a> user like me to effectively be converted to Emacs, but at least I&#8217;m trying&#8230;</p>
<h3 style="text-align:justify;">Introducing and Installing the Package</h3>
<p style="text-align:justify;">A description From <a href="http://emacs.orebokech.com/">emacs-snapshot</a> site says:</p>
<blockquote>
<p style="text-align:justify;"><em>emacs-snapshot is a set of packages of the CVS version of GNU Emacs  for the Debian operating system. It is updated regularly from the CVS trunk. Two flavors are available: a GTK version (emacs-snapshot) and a console-only version (emacs-snapshot-nox).</em></p>
<p><em>The recommended version for desktop users is emacs-snapshot. For servers, emacs-snapshot-nox is usually a better choice since it has minimal dependencies.</em></p></blockquote>
<p style="text-align:justify;">It means you need to do a choice between terminal or desktop, right? yes and no. In my opinion the best way to use Emacs is at terminal, but I recommend you to install both and just after the installation you do a real choice. In Debian it is easy to set which alternative version you&#8217;d like to run using the command <a href="http://www.debian.org/doc/FAQ/ch-customizing.en.html">update-alternatives</a>. I&#8217;ll explain this later&#8230; for now let&#8217;s focus on add the emacs-snapshot repository.</p>
<p style="text-align:justify;">For now on, you should use sudo or run all the commands below as root. Open up a terminal and run the command:</p>
<pre style="text-align:justify;">$ nano /etc/apt/source.list</pre>
<p style="text-align:justify;">Now lets add the repository line. If you are running Debian Testing or Unstable like me, you will add the line below and save the file (For Debian Stable, use lenny instead of sid):</p>
<pre style="text-align:justify;">deb http://emacs.orebokech.com sid main
deb-src http://emacs.orebokech.com sid main</pre>
<p style="text-align:justify;">
<p style="text-align:justify;">Good, we have the repository. Now lets get the Romain&#8217;s GPG key. You need to teach your Debian box to add that gpg key in the trusted repositories keyring. Use the commands below for your convenience (adding the key and refreshing the repository list):</p>
<pre style="text-align:justify;">$ wget -q http://orebokech.com/Romain_Francoise.pgp -O- | apt-key add -
$ aptitude update</pre>
<p style="text-align:justify;">Good, we are OK to install the package. Go ahead and get the packages:</p>
<pre style="text-align:justify;">$ aptitude install emacs-snapshot emacs-snapshot-nox</pre>
<p style="text-align:justify;">Done, we accomplish the installation process. By default, when you type <em>emacs</em> at the terminal, the GTK version will open up. Alternatively you can use the <strong>No X</strong> version (terminal version). Completing the next steps to change it.</p>
<h3 style="text-align:justify;">Using update-alternatives</h3>
<p style="text-align:justify;">The rest of this tutorial will teach you how to use the command update-alternatives to choice what emacs alternative you would like to run by default. Debian has a way of setting up these system alternatives of your favorites programs, like to setup which editor is your main, or what browser is the default; using update-alternatives is not hard, but the manpage can be confusing on how it is done. To understand this command, I recommend you the tutorial <a href="http://linuxbasics.org/tutorials/using/debian_update-alternatives">http://linuxbasics.org/tutorials/using/debian_update-alternatives</a>.</p>
<p style="text-align:justify;">To setup which version you would like to use, run the following command, typing the alternative number you prefer:</p>
<pre style="text-align:justify;">$ update-alternatives --config emacs-snapshot
There are 2 choices for the alternative emacs-snapshot (providing /usr/bin/emacs-snapshot).

Selection    Path                         Priority        Status
-------------------------------------------------------------------
  0            /usr/bin/emacs-snapshot-gtk   0         auto mode
  1            /usr/bin/emacs-snapshot-gtk   0         manual mode
* 2            /usr/bin/emacs-snapshot-nox   0         manual mode

Press enter to keep the current choice[*], or type selection number:</pre>
<p>Hit the enter key&#8230; next time you run emacs, it will load you preferred version.</p>

<p>Git é legal e rápido, Github tem uma comunidade grande, tenho vários amigos usando github, motivos não faltavam para usar/preferir Github&#8230; até que eu descobri o Bitbucket que é praticamente o mesmo que Github, exceto por uma feature que fez toda diferença para eu decidir mudar: um repositório privado!!! mesmo para quem tem conta free.</p>
<p>Por que esse repositório privado é importante para mim? porque as vezes queremos trabalhar em algo que é secreto, só nosso e que pode ficar pronto em breve mas ainda não está. Somente depois de um tempo trabalhando secretamente eu então posso marcar o repositório como público&#8230; fez toda diferença pra mim <img src='http://s0.wp.com/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>
<p>E se você tem conta lá, a minha é: <a href="http://bitbucket.org/carloscosta/">http://bitbucket.org/carloscosta/</a></p>

Today I received a cool (or not) e-mail says that my page will be moved to another service or (at my choice) I can download all files and redirect the link to another one. I chose the second option. Now I need to fix the broken links on this blog, most of then related with pdf files, txt and pictures of mine.</p>
<p>Pardon if you don&#8217;t download any file, I can&#8217;t fix all links yet&#8230; and if you find a broken link, please report me. I&#8217;m glad to know your interest about the stuffs I&#8217;m sharing.</p>
<p>Thank you!</p>

			<content:encoded><![CDATA[<p>Apesar de <span style="text-decoration:line-through;">quase</span> Feliz usuário do wordpress.com por pelo menos os últimos 2 anos, existem problemas nele que vez por outra me deparo e quase sempre me aborreço. Os principais estão relacionados com o modelo <a href="http://en.wikipedia.org/wiki/WYSIWYG">WYSIWYG</a> adotado por eles e os temas propostos que são feios e sem usabilidade. Aliás, alguém precisa avisar o mundo que Browser não foi feito para ser editor de textos, ninguém me convence do contrário (nem <a href="http://www.google.com">eles</a>). Se já é difícil editar usando softwares tipo word, imagina usar um Browser (CSS, HTML e JavaScript) <img src='http://s2.wp.com/wp-includes/images/smilies/icon_razz.gif' alt=':P' class='wp-smiley' /> </p>
<p>Mas o wordpress.com atende bem a maioria que só quer escrever. E com a adição de alguns serviços pagos dá pra melhorar algumas coisas por aqui, mas nem tudo o dinheiro compra né?! eu tenho domínio próprio, mas não tema personalizado. Eles até oferecem um serviço de custom CSS onde você escolhe o tema e pode modificar ligeiramente o visual do mesmo, mas a estrutura do tema permanece estática. Pensando nessas dificuldades, parei de me lamentar e procurei uma alternativa&#8230; até que eu achei: <a href="http://www.github.com">github</a>!!!!</p>
<p>Inspirado nas infinitas possibilidades de uso do <a href="http://en.wikipedia.org/wiki/Git_(software)">Git</a>, um dos mais sensacionais softwares inventados até hoje (ops, <a href="http://en.wikipedia.org/wiki/Linus_Torvalds">he</a> did it again), os caras do github construiram uma infraestrutura de host pra projetos de sofware que dá inveja nos concorrentes (eu acho). É surpreendente a quantidade de features disponíveis, e como a rica API deles te permite explorar outras infinitas possibilidades&#8230; e uma delas me chamou a atenção: Host the <a href="http://github.com/blog/272-github-pages">páginas</a>. Você cria um repositório pro seu site pessoal, cria um pequeno arquivo de CNAME, muda seu DNS e pronto, seu site devidamente hosteado. Alias, dá até pra ter um blog rodando lá, com a ajuda disso <a href="http://github.com/mojombo/jekyll/">http://github.com/mojombo/jekyll</a></p>
<p>Eu já tenho um usuário criado lá, próxima etapa é fazer algumas experiências e, quem sabe, migrar todo o meu conteúdo daqui para lá. Acompanha ai que eu vou reportando as coisas daqui. E se você quer saber mais sobre como criar páginas lá, olha algumas referências:</p>

			<content:encoded><![CDATA[<p>Lets suppose you are connected &#8211; via the <a href="http://en.wikipedia.org/wiki/Virtual_private_network">VPN</a> &#8211; with <a href="http://www.gnu.org/software/screen/screen.html">screen</a> in a remote server when you lost your connection, the VPN is down and your screen session still attached in the remote server. How to get back the unattached screen? First, redo your login, reopen your ssh and get back access to your remote server.</p>
<p>After restore your connection, you should use screen to list session still attached:</p>
<pre style="padding-left:30px;">[root@localhost ~]# screen -ls
There is a screen on:
         16176.pts-0.localhost    (Attached)
1 Socket in /var/run/screen/S-root.</pre>
<p>Now is simple, just call screen with -U -R to get back your session:</p>
<pre style="padding-left:30px;">[root@localhost ~]# screen -U -R</pre>
<p>And you will be back on track <img src='http://s1.wp.com/wp-includes/images/smilies/icon_wink.gif' alt=';-)' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>Acho que alguns amigos fanboys da Apple irão ler aqui e deixar cometários bem carregados de ódios ehehehehe</p>
<p>Tudo começou quando eu procurei por um bom hardware, core 2 duo no mínimo, pequeno e barato. Capaz de executar QEMU sem engasgar (T42 não dá mais conta), onde eu pudesse compilar/linkar/testar e ainda ficar com leitor de e-mail e outros programas abertos. Ele teria que ser barato (em promoção é melhor), silencioso e pequeno. Eu já tinha um monitor LG de 14&#8243; e um teclado, só faltava o hardware. Foi então que eu vi na saraiva um Apple Macmini core2duo com 1GB e disco de 80GB, por um preço 300 reais mais barato que nos outros sites. Comprei <img src='http://s0.wp.com/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>
<p>A parte chata é que eu não rodo Mac OS, e nem pretendia. Comprei e instalei Debian nele. Alguns vão dizer que Unix é Unix, seja Mac OS, GNU/Linux, FreeBSD: é tudo basicamente Unix, certo?! errado!!!! eu não me adaptei ao Mac OS. Várias coisas fazem falta ali, mas tem uma que me lembra windows: não tem package management system. Como alguém ainda consegue viver sem isso no mundo de hoje?! Bom, os passos para a libertação são:</p>
<ol>
<li>tira da caixa, espeta um teclado e um mouse, liga ele, bota no Mac OS, fornece os dados que ele te pede até que vc começe a usar de fato o SO;</li>
<li>Usando o utilitário de manipulação de disco da Apple, reparticiona o disco. Mac OS utiliza HFS, mantenha assim. No meu caso partir na metade o disco foi suficiente pois uso um disco externo como /home;</li>
<li>Baixa e Instala o <a href="http://refit.sourceforge.net/">http://refit.sourceforge.net/</a> bootloader no Mac OS. Com ele vc consegue instalar o Debian de boa;</li>
<li>Insere o CD do debian 5 e manda reboota o macmini. Na tela do rEFIt, escolha bootar pelo CD. Siga a instalação do debian normalmente, no meu caso mantive o Gnome padrão mesmo;</li>
<li>Terminou de instalar, reboot&#8230; escolha o disco rotulado como Linux e boote. Sem erros, sem mistérios, vc cai na Tela do GDM e loga no sistema, todo o hardware reconhecido e instalado, até wireless reconheceu <img src='http://s1.wp.com/wp-includes/images/smilies/icon_wink.gif' alt=';-)' class='wp-smiley' /> </li>
<li>Passos além (opcionais): muda pro debian testing, instala cliente de VPN da empresa, configura cliente de email, repositórios adicionais e pacotes preferidos e pronto: Bom hardware rodando agora um bom software <img src='http://s0.wp.com/wp-includes/images/smilies/icon_biggrin.gif' alt=':-D' class='wp-smiley' /> </li>
</ol>

			<content:encoded><![CDATA[<p>Já faz algum tempo que eu quero escrever este post, meio que finalizando o trabalho que começou <a href="http://carloscosta.org/2009/01/12/curso-sistema-operacional-linux/">aqui</a> e <a href="http://carloscosta.org/2009/01/18/curso-sistema-operacional-linux-atualizado/">aqui</a>. Mas sempre tinha algo que não me deixava concluir o texto. Mas chegou a hora de finalizar. A minha primeira vez (como professor) foi assim:</p>
<ul>
<li>Um curso sobre sistema operacional linux para o ensino (escola pública) técnico/profissionalizante, voltado para uso intensivo de terminal, scripts para automação de tarefas, e alguns aspectos internos dos sistemas GNU/Linux como init, processos e runlevels. Todo o conteúdo trabalhado teve foco na formação de sysadmin junior e não focou em distribuição especifica. Levou pouco mais de 3 semanas.</li>
<li>Logo na primeira semana eu fiz questão de derrubar o mito de hackers serem sinônimos de vandalismo e criminalidade. Software Livre, GNU, Linux, tudo isso foi (é) feito por bons hackers. Para a primeira avaliação eu pedi que eles pesquisassem <a href="http://carloscosta.org/2009/01/18/curso-sistema-operacional-linux-atualizado/">técnicas de invasão de servidores</a>, entregando relatórios sobre os assuntos. Para minha surpresa todos entregaram bons trabalhos, mostrando que mesmo antes de fazerem meu curso, todos possuiam noções fundamentais sobre os tópicos propostos. Também mostraram sintonia (trabalho em equipe) muito boa.</li>
<li>Na semana seguinte todo o conteúdo apresentado manteve-se fiel ao que normalmente se cobra em exames da LPI, exceto quando o examo mencionava aspectos relativos as distribuições, como package manager, que eu preferi não abordar. No final da semana eu elaborei uma prova com questões retiradas das provas de certificação e a média da turma foi 8 (prontos para uma prova oficial de certificação, não acham?!).</li>
<li>Na última semana abordei somente shell scripts. Todos tinham boas noções de programação, lógica, e entenderam rapidamente instruções For, While e If. Avaliei novamente os alunos com uma prova pratica, onde eles escreveram scripts para resolver pequenos problemas. Novamente as notas foram ótimas.</li>
</ul>
<p>Trabalhar como educador só é prazeroso quando existe uma correspondência multua entre as partes (professor e alunos), e neste caso a multualiade foi plena, uma vez que este professor tem satisfação de espalhar GNU/Linux mundo afora e os alunos tiveram prazer de aprender. sou grato ao Ceprocamp por permitir que eu fosse o professor desta turma especial:</p>
