Replace default Nautilus with alternative file manager

OS: Ubuntu 11.10

Ubuntu has a solution posted here: https://help.ubuntu.com/community/DefaultFileManager
But it seemes a little awkward for my needs.

So after little google'ing and grep'ing here are the steps:
1) Install alternative file manager (pcmanfm in my case):
sudo apt-get-install pcmanfm
2) Make sure that installed application has *.desktop files for folder handling (again for pcmanfm):
cd /usr/share/applications/
ls *-home.desktop *-folder-handler.desktop
# Here we should see 2 files for nautilus and same ones for our file manager
# If those're missing, one should manually create *.desktop description files for "folder-handler" and "home". Use nautilus' files as examples.
3) For system wide config, edit /etc/gnome/defaults.list, replace variables:
inode/directory
x-directory/normal
with appropriate *.desktop files (pcmanfm example):
inode/directory=pcmanfm-folder-handler.desktop
x-directory/normal=pcmanfm-folder-handler.desktop
3) Per user config: go to user's home dir and edit:
.local/share/applications/mimeapps.list
replacing inode/directory entry in [Default Applications] with required *.desktop file, example:
inode/directory=pcmanfm-folder-handler.desktop

Done.

Replace metacity with openbox in Unity2d

Tested with Ubuntu 11.10
Below, there are few steps to tweak Default Ubuntu's Unity2D environment little lighter. This will give some speed up, at a cost of simplifying desktop's visual style.
Window manager is an application responsible for window decoration drawing, e.g. buttons, title, borders etc.
Openbox is a small, fast, lightweight window manager.
Metacity is gnome's default window manager (nice, yet sometimes choppy and slow).
Unity 2d -- is lightweight alternative for Ubuntu's default desktop environment.

Preconditions:
Unity 2d installed.
Steps:

1. Install openbox:

   sudo apt-get install openbox

2. Optionally install additional packages (in my case these were installed as dependencies):

   sudo apt-get install obconf openbox-themes

3. Edit /usr/share/gnome-session/sessions/2d-ubuntu.session file and replace:

   DefaultProvider-windowmanager=metacity

   with

   DefaultProvider-windowmanager=openbox

4. Logout, login (with Unity 2d session).
5. Run obconf, choose some nice theme (my was found on box-look.org and changed a little) and configure buttons position.

Enjoy!

Dumping traffic (wireshark, tcpdump) without root privileges

The idea: grant privileges (capabilities) to traffic dumper application (setcap to dumpcap).
Tested with: Ubuntu 11.04
Steps (in terminal as root):

addgroup -quiet -system wireshark
chown root:wireshark /usr/bin/dumpcap
setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap
usermod -a -G wireshark YOUR_USER_NAME

Global East Open Air 2010 Rock Festival.

Never imagined that far Eastern Europe could ever bring such an extra-impressive metal festival involving music legends from all over the world.
But h3ll yes! That is exactly what has just happened near Kyiv/Kiev (Ukraine):
Three days of total metal madness, metal energy and mind-blowing drive!

Running order can be found here:
http://mus-review.blogspot.com/2010/08/rozklad-ge.html
So, to pour some more light on it, a few words below.

Day one
(Long road, broken bus, long entry, great wild night).

Day two
(Heavy-metal under heavy-rain rocks, legends of black show themselves, night surprise).


Day three
(Naturally wild metalhead, more legends one after another).
Cruachan fiddler really had success in tutoring croud with dirty-russian :)
Could be too much for one day, but... "we want more!"
Home coming train, but music still in my brain.


Q: Troubles, adventures?
A: Some... just to bring more fun ;)
Q: Organisation?
A: Still few things to work on (Actually, there always are).
Q: Festival information accessibility.
A: That surely a thing that should be improved (slow web-page, mainly in Russian/Ukrainian, somehow unaware fest-guards etc.)
Q: Epic fail?
A: Manowar refused to come. And this information was confirmed in 3 weeks before concert. Well, never considered them worth admiring, and they've proved that. So who cares about those a***oles now? :)
Q: Epic win?
A: Everything else. Especially finalE (with Dark Tranquillity and Haggard performed just-perfect). Oh, now having a ticket signed by DT guys, happy-happy-happy!
Q: Was it worth coming?
A: 200% surely Yes!!!
