+Git research and development.
+
+Barebones shared git repositories
+---------------------------------
+
+No gitolite, gitosis, gitlab or whatever involded. Only OpenSSH and git is needed.
+
+### Basic config
+
+If needed, create a host instance for your git server at your `~/.ssh/config`:
+
+    Host git.project.org gitserver
+      HostName git.project.org
+
+Now make sure you can log into the server using key-based auth.
+
+### Server config
+
+    sudo apt install git
+    sudo adduser git --home /var/git
+    sudo mkdir              /var/git/repositories
+    sudo chown git.         /var/git/repositories
+    sudo chmod 775          /var/git/repositories
+    sudo usermod -a -G git `whoami` # add yourself into the git group
+
+### Creating a repository
+
+At your computer:
+
+    repo="name-your-project-here"
+    mkdir $repo
+    cd $repo
+    git init
+    git remote add origin ssh://gitserver/var/git/repositories/$repo.git
+
+Then do your regular stuff: create files, commit stuff, etc:
+
+    touch test
+    git add .
+    git commit -m "Initial import"
+
+### Copy a bare git repo to the server
+
+    cd ..
+    git clone --bare $repo $repo.git
+    scp -r $repo.git gitserver:/var/git/repositories/$repo.git
+
+### Making the repository shareable
+
+In the server:
+
+    sudo chgrp -R git /var/git/repositories/$repo.git
+    sudo chmod 775    /var/git/repositories/$repo.git
+
+    find /var/git/repositories/$repo.git/ -type f -exec sudo chmod 664 {} \;
+    find /var/git/repositories/$repo.git/ -type d -exec sudo chmod 775 {} \;
+
+Now make sure that the repository configuration has the following option at the `core` section:
+
+    sharedRepository = group
+
+You can edit `/var/git/repositories/$repo.git/config` to add this config or just run
+the following commands:
+
+    git -C /var/git/repositories/$repo.git config core.sharedRepository group
+
+### Daily workflow
+
+From now on, you can work at your computer's local `$repo` as usual:
+
+    cd $repo
+    git pull
+    touch another-test
+    git add .
+    git commit -m "Adds another-test"
+    git push # this sends changes back to your git server
+
+### Adding more users into the game
+
+You can add existing users to edit the repository given that:
+
+* They have accounts in the system.
+* They are added into the `git` group.
+
+If they also use key-based auth they can seamlessly contribute to your repository
+as if you were using a more complex repository manager like gitolite or a service
+like gitlab.
+
+You can even try to implement some more complex access control by using different
+groups for each project so you're not bound to the `git` group.

+## Important note
+
+From [Libreboot – Installation instructions](https://libreboot.org/docs/install/index.html):
+
+> NOTE: if running flashrom -p internal for software based flashing, and you get
+> an error related to /dev/mem access, you should reboot with iomem=relaxed
+> kernel parameter before running flashrom, or use a kernel that has
+> CONFIG_STRICT_DEVMEM not enabled.
+
+Or you might get errors like this:
+
+    user@x60s:~/code/libreboot/libreboot_r20160907_util/flashrom/i686$ sudo ./flashrom_lenovobios_sst -p internal -r factory.bin
+    flashrom v0.9.9-unknown on Linux 4.9.0-2-686-pae (i686)
+    flashrom is free software, get the source code at https://flashrom.org
+
+    Calibrating delay loop... OK.
+    Found chipset "Intel ICH7M".
+    Enabling flash write... Error accessing ICH RCRB, 0x4000 bytes at 0xfed1c000
+    /dev/mem mmap failed: Operation not permitted
+    FAILED!
+    FATAL ERROR!
+    Error: Programmer initialization failed.
+    user@x60s:~/code/libreboot/libreboot_r20160907_util/flashrom/i686$ sudo ./flashrom_lenovobios_macronix -p internal -r factory.bin
+
+## Pre-compiled binaries
+
+[Get the latest stable release](https://libreboot.org/download.html), check integrity, etc.
+
+In my case I only needed these, which were the latest releases at the time of writing:
+
+* https://mirrors.peers.community/mirrors/libreboot/stable/20160907/SHA512SUMS
+* https://mirrors.peers.community/mirrors/libreboot/stable/20160907/SHA512SUMS.sig
+* https://mirrors.peers.community/mirrors/libreboot/stable/20160907/libreboot_r20160907_util.tar.xz
+* https://mirrors.peers.community/mirrors/libreboot/stable/20160907/rom/grub/libreboot_r20160907_grub_x60.tar.xz
+
+Download and unpack bot libreboot util and rom tarballs. In this example I used the following paths:
+
+* `~/code/libreboot/libreboot_r20160907_util`
+* `~/code/libreboot/roms/libreboot_r20160907_grub_x60`
+
+## Building from source
+
+Just if you need to:
+
+    git clone https://notabug.org/libreboot/libreboot.git && cd libreboot
+    sudo ./oldbuild dependencies trisquel7
+    ./download all
+    ./oldbuild module all
+
+## x60s
+
+This is how I've done. The actual procedure might change without notice :P
+
+### Overview
+
+* Backup the original firmware [like said](https://www.coreboot.org/Board:lenovo/x60/Installation#Back_up_the_original_proprietary_firmware).
+* Then flash the new ROM as [said here](https://libreboot.org/docs/install/#flashrom_lenovobios).
+
+Note this [funny note](https://en.wikibooks.org/wiki/Libreboot/Install/ThinkPad_X60_and_T60)
+on customized and solitary proprietary software:
+
+> While backing up the proprietary BIOS image might be construed as "endorsing"
+> proprietary software: This BIOS image is unique to every motherboard. It will
+> be impossible to restore the original BIOS once it is lost. Back it up now or
+> you will lose it forever. Do not take this decision lightly.
+
+### BIOS Backup
+
+    user@x60s:~/code/libreboot/libreboot_r20160907_util/flashrom/i686$ sudo ./flashrom_lenovobios_sst -p internal -r factory.bin

+[[!meta title="Free and Open Source Services"]]
+
+This is a FOSS listing for service hosting. Staying on this list doesn't mean
+that a given software is recommended or audited in the spirit of the [Franklin
+Street Statement on Freedom and Network
+Services](http://wiki.p2pfoundation.net/Franklin_Street_Statement_on_Freedom_and_Network_Services).
+
+What to look for when chosing:
+
+1. Portability: how easy is to export and import data into a service?
+2. Maintenance: how easy is to install, upgrade, migrate and restore the service?
+3. Security: how secure the service look like? How upstream handles security? What's the service security track record?
+4. Stability: does the system is stable or is full of bugs?
+5. Maturity: does the architecture and data model of the service changes very often? Are there a community and many developers?
+
+Sometimes is better not run a service than to do it poorly.

+[[!meta title="Mensageria Suckless"]]
+
+Quem não comunica se trumbica. Mas quem comunica também. Porque tá cheio de
+sistema por aí que te afaga e te apedreja ao mesmo tempo. Oferece serviço de
+vigilância gratuita que possui funcionalidade de comunicação.
+
+Aqui queremos a boa e velha mensageria suckless, que também é uma merda, mas é
+uma merda menor do que o enlatado baseado em soluções proprietárias oferecido
+pelas startups turbocapitalistas.
+
+Isto aqui é um esboço! Patches são bem vindos :)
+
+Requisitos
+----------
+
+* Seja independente de plataforma e independente de um computador móvel como
+  smartphones.
+
+* Sessão persistente: podem te enviar mensagem mesmo que você não esteja online.
+  Melhor ainda, que você conste como online mesmo que não esteja acessando a
+  mensageria.
+
+* Um mínimo de privacidade: conexão cifrada com o servidor, criptografia
+  ponta-a-ponta com negação plausível pra falar com os/as amiguinhos, sem logs.
+
+Ingredientes
+------------
+
+1. Conta shell num servidor com bom uptime e acesso SSH.
+
+2. Mutiplexador de terminal.
+
+   É uma espécie de "gerenciador de janelas" para
+   a linha de comando que permite manter programas
+   rodando em background mesmo quando o terminal
+   é fechado.
+
+   Ele permite que malandros deixem a mensageria
+   IRC rodando no servidor mesmo que não estejam
+   conectados via SSH.
+
+   Exemplos: tmux e screen
+
+3. Cliente de IRC
+
+   Exemplos: irssi e weechat
+
+Howto
+-----
+
+Logando e instalando:
+
+    ssh servidor-remoto
+    sudo apt install tmux irssi irssi-plugin-otr
+
+Criando uma sessão para o IRC:
+
+    tmux
+
+Abrindo o cliente e se conectando no rolê:
+
+    irssi
+
+Para sair da sessão sem encerrar a mensageria, digite Ctrl B D
+(control sequence do tmux mais o comando "detach"). Depois é
+só encerrar a shell do servidor remoto.
+
+Para se reconectar, basta
+
+    ssh servidor-remoto tmux attach
+
+Básico do IRC
+-------------
+
+    /network add -nick <nick> -realname <realname> freenode
+    /server add -auto -ssl_verify -ssl_capath /etc/ssl/certs -network freenode chat.freenode.net 7000
+    /save
+    /connect freenode
+    /join #canal
+
+Bônus
+-----
+
+* Tor.
+* Bitlbee.
+
+Privacidade
+-----------
+
+Note que uma sessão persistente implica no cliente rodando num
+servidor. Isso pode degradar sua privacidade, uma vez que o servidor
+pode ser comprometido de várias formas. É importante ter consciência
+disso.
+
+Da mesma forma que seu celular pode ser invadido, roubado e ter dados extraídos,
+um servidor também é um ponto vulnerável na sua comunicação, especialmente
+se for nele que as chaves criptográficas estiverem armazenadas.
+
+Assim, a sessão persistente de mensageria oferece um nível de segurança apenas
+intermediário, servindo para a comunicação do dia-a-dia que não for sensível.
+
+Para comunicação sensível, o melhor é rodar o cliente de mensageria diretamente
+a partir do seu [Console Físico Confiável](https://opsec.fluxo.info/specs/tpc).

+[[!meta title="We are the static site generation!"]]
+
+# Current practice
+
+Currently [ikiwiki](http://ikiwiki.info) is adopted by the following reasons:
+
+1. There is a [Debian package](https://packages.debian.org/stable/ikiwiki).
+2. It's flexible enough to support both local or remote side static compilation:
+   * Local compilation by calling the `ikiwiki` command directly.
+   * Remotelly by using a [git hook](http://ikiwiki.info/rcs/git/).
+
+When it's said **both** it means that you don't need to choose either of the two options: you can choose or both simultaneously.
+
+## Static site example
+
+Here comes the mandadoty "Hello world" example from the statically generated site realm:
+
+    mkdir blog && cd blog
+    echo "Hello world..." > index.mdwn
+    ikiwiki --rebuild --exclude www . www
+
+That's it! You have a generated site sitting at your `www` subfolder which can be copied remotelly using `rsync`.
+
+## Version control
+
+It's a good pratice to keep your work under version control:
+
+    git init
+    echo "/.ikiwiki"       > .gitignore
+    echo "/recentchanges" >> .gitignore
+    echo "/www"           >> .gitignore
+    git add .
+    git commit -m "Initial import"
+
+## Add a bit of sofistication
+
+* Use [this Makefile](/Makefile) as an starting point to refresh and publish your wiki by simply running `make web`.
+* Use a [complete ikiwiki template](https://git.fluxo.info/?p=templates.git;a=tree;f=ikiwiki;h=HEAD) and change to your needs.
+* If you're a automation junkie, try the [puppet-ikiwiki](https://git.fluxo.info/puppet-ikiwiki.git) module.
+
+## Theming
+
+Currently using [Ikiwiki](http://ikiwiki.info) with [Bootstrap](http://twitter.github.io/bootstrap/):
+
+* [Templates](https://github.com/tgpfeiffer/ikiwiki-bootstrap-template).
+* [Bootswatch](http://bootswatch.com) themes.
+
+## Deployment
+
+You can create passwordless SSH keys and use [rrsync](http://www.guyrutenberg.com/2014/01/14/restricting-ssh-access-to-rsync/) ([2](http://wiki.hands.com/howto/passphraseless-ssh/)) to restrict access. Then add an entry into your `~/.ssh/config`:
+
+    Host blog.example.org blog
+      HostName blog.example.org
+      User blog
+      IdentityFile ~/.ssh/blog@blog.example.org
+
+Now simply run `make web_deploy` with the above mentioned `Makefile` do sync your static site!

+[[!meta title="Virtualized GUI environments"]]
+
+Can't or don't want to use [Qubes OS](https://www.qubes-os.org/)? Here comes a straightforward sollution
+that, while not offering the same level of security, is practical enough to be implemented in the confort
+of your current FOSS OS!
+
+A picture
+---------
+
+Could you spot the difference between the Tor Browser running in the host for the one inside the virtual machine? That's what we want to achieve!
+
+![Screenshot](screenshot.png)
+
+First things first
+------------------
+
+What you can do:
+
+1. Create a virtual machine image of the operating system of your choice like [this example](https://padrao.fluxo.info/boxes/).
+2. Setup basic X11 environment with automatic login and startup programs.
+3. Configure your hypervisor to hide icons and additional decorations around the virtual machine.
+4. Setup key bindings on your window manager to start/resume and stop/suspend the virtual machine.
+
+Debian desktop
+--------------
+
+When using a debian virtual machine as a virtual desktop, consider the following:
+
+    apt-get install lightdm ratpoison
+
+Make sure to configure `/etc/lightdm/lightdm.conf` with something like
+
+    autologin-user=vagrant
+    autologin-user-timeout=0
+
+If using VirtualBox, you might also want to try [virtualbox-guest-x11](https://packages.debian.org/stable/virtualbox-guest-x11).
+
+Features
+--------
+
+* Good security through isolation.
+* Improved start/stop of your application by using virtual machine suspend/resume.
+* Minor performance penalties while running the virtual machine.
+
+Limitations
+-----------
+
+* Memory and disk consumption.
+* Clipboard might still be available to the virtual environment, see [this discussion](http://theinvisiblethings.blogspot.com.br/2011/04/linux-security-circus-on-gui-isolation.html).
+
+Future
+------
+
+* This should be better documented!
+* Automated expendable snapshots for one-time-use virtual machines.
+* Automated recipes (puppet/ansible).
+* Vagrant integration for fast provisioning of golden images.
+* Alternatives to the VirtualBox hypervisor.

+[[!meta title="ThinkPad"]]
+
+Esta é uma pesquisa em andamento sobre [ThinkPads](https://en.wikipedia.org/wiki/ThinkPad).
+
+## Política
+
+É sempre bom lembrarmos das origens das linhagens técnicas. Como o Fusca, que
+foi [concebido pelo Porsche para ser um carro resistente e de fácil
+manutenção](https://hackaday.com/2016/05/03/volkswagen-beetle-the-most-hackable-car/).
+
+Aqui segue um brainstorm (ou thinkstorm?) que pode ser desenvolvido com mais
+propriedade.
+
+### Think
+
+[De onde vem o slogan THINK](/books/history/ibm-holocaust):
+
+    NCR salesmen wore dark suits, the corporation innovated a One Hun-
+    dred Point Club for agents who met their quota, and The Cash stressed "clean
+    living" as a virtue for commercial success. One day during a pep rally to the
+    troops, Watson scrawled the word THINK on a piece of paper. Patterson saw
+    the note and ordered THINK signs distributed throughout the company.
+    Watson embraced many of Patterson's regimenting techniques as indispens-
+    able doctrine for good sales. What he learned at NCR would stay with him
+    forever.
+
+    -- do livro IBM and The Holocaust, pág. 42
+
+    Large pictures of Watson in the weekly company publication, Business
+    Machines, regularly sported headlines proclaiming even his ordinary accom-
+    plishments, such as "Thomas J. Watson Opens New Orleans Office." The ever-
+    present equating of his name with the word THINK was more than an
+    Orwellian exercise, it was a true-life indoctrination. The Watson mystique
+    was never confined to the four walls of IBM. His aura was only magnified by
+    his autocratic style
+
+    -- do livro IBM and The Holocaust, pág. 47
+
+Esse aí é o DNA da IBM. Não é de se estranhar que tenha sido tão fácil para a
+Apple capitalizar em cima dos hobbystas da computação pessoal e se colocar como
+uma alternativa humanizadora ao "Grande Irmão" de gigantes da computação
+monolítica como a IBM.
+
+Não há como operacionalizar um império se nao houver uma classe mínima de escribas,
+sejam corporativos ou estatais e que sejam encorajados a pensar dentro dos limites
+e ditames do regime.
+
+Mais um ponto pra tese de que nazismo não foi só baseado no arcaísmo da "terra e
+sangue" mas também numa racionalidade técnica. Havia pensamento, inteligência e
+estratégia, mas para todos os propósitos irracionais, boçais, torpes e banais,
+mostrando que mesmo na sapiência pode haver a demência.
+
+### A Classe dos Escribas
+
+O ThinkPad é um equipamento de produtividade feito para ajudar a pensar
+estrategicamente. Talvez seja o melhor computador pra isso pelo seu design
+potencializador da simbiose humano-máquina.
+
+É um ápice dos PCs conhecidos como laptops ou notebooks, funcionando muito bem
+para o processamento da linguagem escrita. Daí que é muito confortável para o
+público letrado que produz código.
+
+### A nova ideologia
+
+> O lance é...
+> Na nova ideologia, o slogan mudou
+> Nao eh mais **THINK**
+> Mas sim **INTERACT**
+> Daí que as recentes linhagens técnicas tem outro design
+> Pra facilitar uma interação instantânea, não para pensar
+
+Não que o slogan anterior tenha sido abolido, mas ele é minoritário numa indústria
+da computação onde a maior parte dos consumidores não está sendo tratada como
+classe pensadora, mas como meros terminais de interação entre o mundo e as
+"nuvens" computacionais (o antigo "mainframe" do paradigma totalitário
+clássico).
+
+O Pad está para o THINK assim como o Pod está para o INTERACT.
+
+Não é à toa que a IBM é uma empresa do século passado apesar de ainda ter uma
+certa preponderância em IA e Big Data. Mas sua identidade de uma empresa de
+pesquisadores ligados às ciências duras tem sido suplantada pouco a pouco pela
+lógica das neo doctons como Google e Apple.
+
+Não é à toa que a IBM vendeu a linha ThinkPad para a chinesa Lenovo, que
+prontamente alterou diversos aspectos desses PCs para que sejam mais
+interativos.
+
+Como será que a atual classe dos escribas se portará? Permanecerá como estamento
+THINK ou será absorvido pela massa INTERACT conforme funções de escrita sejam
+absorvidas por agentes como "IAs"? Haverá necessidade de uma vasta classe de
+escribas no novo império que está a se desenhar?
+
+### Libertando o design
+
+Assim como o Fusca, o ThinkPad é de fácil manutenção ("serviceable"). Suas
+peças são de fácil instalação e existem manuais detalhados para conserto.
+
+Decorre que é um hardware favorito de boa parte da comunidade hacker que
+entendeu que, de certo modo, já passamos pela época de esplendor dos PCs e e
+que o melhor que fizeram até hoje foram ThinkPads.
+
+Possivelmente, a comunidade do hardware livre fará a engenharia reversa de todo
+esse rolê. E talvez aí haja uma semente para a difusão de uma computação que
+incentive tanto o pensamento quanto a interação de forma emancipatória. Uma máquina
+de pensar popular e acessível como alternativa às tecnotoxinas totalitárias
+do turbocapitalismo.
+
+Texto escrito a partir de um ThinkPad, máquina surgida nas contradições.
+
+## Critérios de escolha
+
+Ok, chega de groselha. Bora falar de hardware.
+
+Bons critérios para escolha de modelos:
+
+1. Facilidade no acesso a componentes, especialmente unidade de armazenamento.
+2. Conector de energia comum.
+3. Bom teclado e trackpoint.
+
+Exemplos: T430, x200, x201, x230.

+## Safenet eToken E5110
+
+No Debian, instale o [MUSCLE](https://pcsclite.alioth.debian.org/):
+
+    sudo apt install libccid pcsc-tools pcscd pcscd libpcsclite1
+
+Plugue a parada e execute:
+
+    opensc-tool --list-readers
+
+## SafeNet Authentication Client
+
+Para uso no mundo corporativo e institucional, como OAB e afins. Você não vai
+querer usar os drivers proprietários a não ser que seja forçado, certo?
+
+Curioso que no fim das contas a OAB conseguiu seu lugar ao sol no mercado
+da certificação digital apesar da implantação do modelo governamental escolhido
+para o certificado raíz brasileiro, história contada no livro
+[Leviatã Eletrônico](http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-45222010000300013).
+
+Enfim, pra usar o eToken E5110 pra assinar documentos no navegador você
+precisará de drivers específicos e proprietários.
+
+Aparentemente a [Gemalto comprou a SafeNet](http://www.gemalto.com/press/Pages/Gemalto-to-acquire-SafeNet,the-worldwide-leader-in-data-and-software-protection.aspx)
+e depois ficou muito mais difícil para baixar o driver do eToken E5110, que além de ser proprietário ainda ficou privativo!
+Maluco fez [até script](https://gist.github.com/dex4er/1354710) pra automatizar essa zica.
+[Aqui](https://site.solutinet.com.br/2015/manuais/instaladores/) há versões recentes das bibliotecas e do cliente de autenticação
+proprietário (dica [daqui](https://diadialinux.wordpress.com/2017/03/02/instalar-etoken-alladin-usar-sites-do-governo-com-certificado-digital-e-assinar-documentos-pdf/)).
