+The testing ISO image works on a USB key.
+
+Using the nvidia (non-free) driver
+----------------------------------
+
+To install the nVidia driver:
+
+  * make sure installed kernel headers (linux-headers) match kernel (linux-image),
+    otherwise DKMS won't build.
+  * install nvidia-driver
+  * run `nvidia-xconfig --query-gpu-info` by hand and set PCI dia BusID
+  * run `nvidia-xconfig --busid=PCI:x:x:x` to generate xorg.conf
+
+BIOS setup
+----------
+
+  * Video -> Switchable graphics -> uncheck Enable Switchable Graphics
+
+GNOME 3
+-------
+
+Disable `gnome-keyring`:
+```
+$ cd /etc/xdg/autostart
+$ mv gnome-keyring-ssh.desktop gnome-keyring-ssh.desktop-
+$ mv gnome-keyring-gpg.desktop gnome-keyring-gpg.desktop-
+```
+
+Remember NumLock state:
+```
+$ gsettings set org.gnome.settings-daemon.peripherals.keyboard remember-numlock-state true

+Objective
+---------
+
+To set up Octopress in its own, isolated Ruby environment
+ 
+Prerequisite
+------------ 
+ 
+Install rbenv to manage Ruby virtual environments.
+
+Create isolated environment:
+
+```
+$ export GEM_HOME=$HOME/octopress.gems
+$ gem install bundler
+$ export PATH=$GEM_HOME/bin:$PATH
+```
+
+`GEM_HOME` and `PATH` need to be set to do any Octopress work.
+
+Clone Octopress:
+
+```
+$ git clone git://github.com/imathis/octopress.git octopress
+$ cd octopress 
+```
+
+Install dependencies and default theme:
+
+```
+$ bundle install
+$ rake install
+```
+
+:warning: If `--path` is passed to `bundle install`, the value is cached
+in `.bundle/config`, and `$GEM_HOME` is subsequently ignored.
+
+Emoji support
+-------------
+
+* Plugin: https://github.com/chriskempson/jekyll-emoji
+  It is actually necessary to add `gemoji` to the Gemfile
+* Images: https://github.com/arvida/emoji-cheat-sheet.com
+* `ln -s .../emoji-cheat-sheet.com/public/graphics/emogis source/images/

+Ports
+=====
+
+Neither `pkg update` nor `portupgrade` can update all ports.
+Dump all origins, then reinstall manually.
+
+Linuxulator
+===========
+
+New CentOS-6 based linux_base requires sysctl:
+```
+compat.linux.osrelease=2.6.18
+```
+
+X11
+===
+
+GDM
+---
+
+Gdm won't work out of the box (black screen):
+
+  * `gdm_lang` cannot be set to a non-UTF-8 locale anymore
+    (if the month name in the current date contains an accent,
+    the greeter will abort).
+  * (at least when using an ATI video card,) user `gdm` needs to be
+    able to access `/dev/dri/card0`:
+    * create group `dri` containing user `gdm`
+    * add devs rules to give it r/w access to `/dev/dri/card0`
+
+Keymap
+------
+
+X will now ignore keymap settings from xorg.conf. Keymap settings must
+now be supplied through HAL policy (`/usr/local/share/hal/fdi/policy/99local/10-x11-keymap.fdi`).
