It is an alternative for a NetworkManager who some time makes me crazy when it doesn’t work as I like. And I have to kill it for work.
Wicd is an open source wired and wireless network manager for Linux which aims to provide a simple interface to connect to networks with a wide variety of settings.
Some of Wicd’s features include:
1. No Gnome dependencies (although it does require GTK), so it is easy to use in XFCE, Fluxbox, Openbox, Enlightenment, etc.
2. Ability to connect to wired (Ethernet only, no PPPoE/DSL support yet) and wireless networks
3. Profiles for each wireless network and wired network
4. Many encryption schemes, some of which include WEP/WPA/WPA2 (and you can add your own)
5. Remains compatible with wireless-tools
6. Tray icon showing network activity and signal strength
7. A full-featured console interface
There are instructions for installing Wicd on Ubuntu, Debian, Arch, Fedora, Slackware, and Gentoo on the downloads page, although it should work on any Linux distro.

Edit your .vimrc settings file to include the following line:
set enc=utf-8
And you should be able to edit a UTF-8 file in Windows using gvim.
For Linux, just set the locale to utf-8 such as:
export LANG=en_SG.UTF-8

Some times we need to limit the traffic that uses some applications. In my case, when I download big files. So:
If we use wget, It is doted with –limit-rate option that permits set the limit of traffic.
Example:
# wget –limit-rate=50k http://lexo.lx-networks.net/testingfile.gz
This example limits wget to uses 50KBps maximum of download traffic.
But … ¿what’s up when we need use other application that it hasn’t the same option like this? Don’t worry, looking for it option I found a solution to do it. 
trickle: is a portable lightweight userspace bandwidth shaper. It can run in collaborative mode (together with trickled) or in stand alone mode.
It works by taking advantage of the unix loader preloading. Essentially it provides, to the application, a new version of the functionality that is required to send and receive data through sockets. It then limits traffic based on delaying the sending and receiving of data over a socket. trickle runs entirely in userspace and does not require root privileges.
Example:
# trickle -s -d 120 -u 100 firefox
This example limits to firefox uses 120KBps for download and 100KBps for upload of traffic.
These are simple methods, because we can use traffic control at kernel level.

Some times we don’t want that command print out messages, and we need to clean all out messages (error or standard out) that it generates. For to solve this, we are going to use the I/O facility provided by BASH.
BASH provide 3 file descriptors, and they are:
0 – stdin – Used for get data.
1 – stdout – Used for write standard data into screen.
2 – stderr – Used for write error messages into screen.
So, using redirector (>) we can redirect(obviously) this data/messages wherever we want and also files.
Examples:
¿How to redirect error messages(stderr) to standard out(stdout)?
ls this.file.doesnt.exist 2>&1
¿How to redirect error messages(stderr) to limbo(/dev/null)?
ls this.file.doesnt.exist 2> /dev/null
¿How to redirect error(stderr) and standard out(stdout) messages to limbo?
ls this.file.doesnt.exist &> /dev/null
or
ls this.file.doesnt.exist 2> /dev/null 1>&2

Today I was installing DAHDI Linux 2.1.0.4 with OSLEC support and this is my little experience with it…
I needed modify drivers/dahdi/Kbuild
# Only enable this if you think you know what you’re doing. This is not
# supported yet:
obj-m += dahdi_echocan_oslec.o
#
# A quick and dirty way to build OSLEC, if you happened to place it
# yourself in the dahdi source tree. This is experimental. See README
# regarding OSLEC.
#obj-m += ../staging/echo/
obj-m += ../staging/echo/echo.o
After I did it, I needed copy echo directory from the kernel linux-2.6.28.7 sources indahdi-linux-2.1.0.3/drivers/staging
cd dahdi-linux-2.1.0.3/
mkdir drivers/staging
cp -r /usr/src/linux-2.6.28.7/drivers/staging/echo drivers/staging
So… I installed the package and enabled the card with OSLEC echo canceller.
