<p>When administering rc.d scripts, it is recommended on Ubuntu to use the sysv_rc_conf (run level configurator for System V like init.d scripts).</p> <p>The command line tool itself has user friendly GUI that makes configuration process painless. Just check/uncheck by using spacebar.</p> <p>Ubuntu <a href="http://ubuntuforums.org/showthread.php?t=1321119" target="_blank">community</a> seemed to endorse it over chkconfig (which is a RedHat tool).</p> <h4>Installation</h4> <pre><code>sudo apt-get install sysv-rc-conf</code></pre> <h4>To Add a Service</h4> <pre><code>sysv-rc-conf nginx on</code></pre> <h4>To Use the GUI</h4> <pre><code>sysv-rc-conf</code></pre> <p>Read its documentation <a href="http://sysv-rc-conf.sourceforge.net/" target="_blank">here</a>.</p>

<p>Installing PIL (Python Image Library) is never a straight forward business. This is tutorial for installing PIL for OS X and Ubuntu Karmic.</p> <p><strong>OS X:</strong></p> <p>&nbsp;&nbsp;&nbsp; sudo port install jpeg<br />&nbsp;&nbsp;&nbsp; # find imaging download link: http://effbot.org/downloads/<br />&nbsp;&nbsp;&nbsp; curl -O http://effbot.org/media/downloads/Imaging-1.1.7.tar.gz<br />&nbsp;&nbsp;&nbsp; tar xvf Imaging-1.1.7.tar.gz<br />&nbsp;&nbsp;&nbsp; cd Imaging-1.1.7<br />&nbsp;&nbsp;&nbsp; sudo python setup.py install</p> <p><strong>Ubuntu Karmic:</strong></p> <p>&nbsp;&nbsp;&nbsp; sudo aptitude install libjpeg62-dev<br />&nbsp;&nbsp;&nbsp; sudo aptitude install zlib1g-dev<br />&nbsp;&nbsp;&nbsp; sudo aptitude install libfreetype6-dev<br />&nbsp;&nbsp;&nbsp; sudo aptitude install python-imaging</p> <p><strong>Notes:</strong></p> <ul> <li>On Karmic, PIL failed to compile using pip or easy_install.</li> </ul>

<p>Locate is a handy tool that fuzzy search files and directories.</p> <p>On Ubuntu Karmic, locate is NOT under findutils NOR slocate package.</p> <p>It is under mlocate. To install, do: <span style="font-size: medium;"><em>sudo aptitude install mlocate</em></span></p> <p>Don't forget to perform <span style="font-size: medium;"><em>updatedb</em></span>, else you will get this error: <em>locate: can not open '/var/lib/mlocate/mlocate.db'<br /></em></p> <p>&nbsp;</p> <p><strong>Reference:</strong></p> <p><a href="http://packages.ubuntu.com/karmic/mlocate" target="_blank">http://packages.ubuntu.com/karmic/mlocate</a></p>
