Script to bind to slow routers by persistent requests to release DHCP information

By
This script is to persistently nag the router to release DHCP information. The script must be run as root. This is for slow routers or one which is overloaded with clients. Do not use for normal routers. Otherwise it could be misconstrued as a security threat.

persistent bind connection DHCP script

# script to persistently nag the router to release DHCP information : must be run as root
# persistent bind connection DHCP script
b=`expr 1`
while [ $b -lt 2 ]
do
echo "Starting new DHCPREQUEST .... after 5 secs ... "
sleep 5
/etc/init.d/networking restart
echo -e "\n xxxxxxxxxxxxxxxxxxxx \n `tail -n 20 /var/log/syslog` \n xxxxxxxxxxxxxxxxxxxx \n"
if [ "` tail -n 20 /var/log/syslog | grep "DHCPOFFER" | grep "of 192"`" ] ;

Fastest way to send multiple drafts from gmail

By
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

By
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
