A script to extract audio from a bunch of video files


This sript extracts the soundtrack from any video format and converts it to mp3. Put all videos in a single folder and run this script on them. This works on all kinds of video. This is specially useful on those bunch of youtube videos.

It works like flv to mp3, mp4 to mp3, avi to mp3 etc.

exit 0
fi

if [ ! `which lame` ] ;then
echo -e "Install lame \nsudo apt-get install lame"
exit 0
fi

IFS=$'\n'

for fullfile in `ls -1`
do
fullfilename=$(basename $fullfile)
# extension=${filename##*.}
filename=${fullfilename%.*}


if [[ `file "$fullfilename" | grep -i "video"` ]]; then
# -i in grep ignores case
echo $filename
else
file "$fullfilename"
echo "Not a video file."
echo "----------"
continue
fi

mplayer $fullfile -ao pcm:file=temp.wav
lame -f temp.wav $filename.mp3

Fastest way to send multiple drafts from gmail

People claim that the fastest way to send multiple email drafts is to use Gmail IMAP with email client like Outlook or Evolution or Thunderbird. But I have found this is not true. Because Thunderbird and Evolution etc. email clients treats the drafts as emails still to be edited. So it is not just simple select all and hit send. Each email draft has to be opened and sent separately. That is a lot of clicks and mouse movements, wasting precious time and energy. I have a better solution which involves minimum keystrokes and mouse usage. Efficiency booster technique for sending emails. If someone is feeling adventurous and want to try it from the Gmail interface itself, here's how to do it in the fastest possible manner. It involves using the mouse once. Select the first draft. Gmail would open a new email box and put the cursor inside the box to write. Press TAB once to go the Send button. Press ENTER to send. Now Gmail sends it and the box is gone but the highlight goes to the last

Changing the font size of section headings in LaTex

You have several ways to do so: 1.- A direct redefinition of \section: \makeatletter \renewcommand\section{\@startsection{section}{1}{\z@}%                                   {-3.5ex \@plus -1ex \@minus -.2ex}%                                   {2.3ex \@plus.2ex}%                                   {\normalfont\large\bfseries}} \makeatother 2.- By means of the titlesec package: \usepackage{titlesec} \titleformat{\section}{\large\bfseries}{\thesection}{1em}{} 3.- By means of the sectsty package: \usepackage{sectsty} \sectionfont{\large} source : http://www.latex-community.org/forum/viewtopic.php?f=4&t=3245   Now, I would explain the titlesec package a bit more (because it seems easier to me and with more options) : To change the section fonts with this package put the following lines in the preamble - \usepackage{titlesec} \titleformat{\ section }{\ large \ bfseries }{\thesection}{1em}{} Options available are- a> Font size - \normals
