2. Video with patch zip with interesting scripts.
3. Spanish instructions also for old o.s. version.

Audacity: Audio Error

Using audacity in fedora 20, Actually I have faced an issue with the audio, strange error as the following one was printed in the terminal:

ALSA lib pcm.c snd_pcm_recover underrun occurred

So in this forum the solution was pointed to restart pulseaudio, which is a proxy sound application:

stop
>pulseaudio --kill
and then restart
>pulseaudio --start

About above command in the forum redirect to this site that explain a little bit further about pulse audio so first need to know your enemy before defeat it.

QDirStat : See Usage files in a path linux

Qdirstat is similar to windirstat, so in this link I've found suggestion to use that tool, so I've installed in fedora 20, because want to check files importants in my disk before format.
Find the source in this link.

I faced an issue with qmake which is fixed just running (link)
yum -y install qt-devel
export qmake=/usr/bin/qmake-qt4

Let's check how to install g++, no remember if I installed it (link).

This site said to install c++
> yum install gcc-c++

Server/Box and DB configuration

1) CHARACTERSET deal
Personally I have faced one issue when I was reading directly from a unix box server to be processed and dump into my oracle database. The unmanaged character was ñ so let's detailed the picture.

********* ini text file ****************
esteban|adulto
aidan|niño
chavela|adulta
nana|niña
********* ini text file ****************

2) Run commands using ssh without need login (link, link2)
ssh -t user@example.com "/home/user/bin/detach ls"

unix recipes

1. Transform lines text into one pipeline separated line (link)
echo $VALUES | tr '\n' ' '

2. Crontab
Check this link to create and a tool to automatic generate line in unix
