<p>&nbsp;</p>
<p>So I&#8217;ve finally come across this little nifty tool and enjoying it, what it does in a 1000km view is to probably the same as init scripts and daemonize your programs.</p>
<p>Supervisord also gives you the ability to control your programs on the web, O.M.G, it also allows you to tail the logs on a browser!  Tip: redirect_stderr=true</p>
<p>It&#8217;s very easy to install, I recommend to install via apt-get if you are on ubuntu so you don&#8217;t need to do extra work.</p>
<p>Check it out!</p>

				<content:encoded><![CDATA[<p>I have been using vim for a few years now and had been using my very own vim configuration, mainly with Nerdtree and CtrlP, in the past few days I have discovered a <a href="https://github.com/carlhuda/janus">well packaged vim configuration</a> with lots of plugins. But shortly I discovered that the tab space is set to 2, which I normally use 4. So I forked the <a href="https://github.com/variable/janus">repository</a> and changed it to suit my style and added some more mappings to navigate between tabs.</p><pre class="crayon-plain-tag">&quot; Tab navigation
noremap &amp;lt;C-h&amp;gt; &amp;lt;C-w&amp;gt;&amp;lt;Left&amp;gt;
noremap &amp;lt;C-l&amp;gt; &amp;lt;C-w&amp;gt;&amp;lt;Right&amp;gt;
noremap &amp;lt;leader&amp;gt;[ gT
noremap &amp;lt;leader&amp;gt;] gt</pre><p>Since the installation script is hardcoded to point to the original repository, if you would like use my own fork, please install via this command:</p><pre class="crayon-plain-tag">curl -lo- https://raw.github.com/variable/janus/james/bootstrap.sh | bash</pre><p></p>

<p>Bought this little device from rsonline UK, for about $60 with clear case including postage, took 2 weeks to get here.</p>
<p>Bought an Apacer Micro SD 32gb class 10 from PBtech for about $58, you can get it cheaper from pricespy but I couldn&#8217;t wait any longer.</p>
<p>I am a mac user so I used the command lines to load the OS image to the card, took about 10-15 mins</p>
<p>First time boot up with goes to the config screen and it didn&#8217;t output hdmi signal, so should use composite cable to config your pi correctly first.</p>
<p>There is an option in the config to expand the partition to use the full SD card capacity, cos after loading the image it only shows about 2gb space, this option allows to use the rest of 30gb.</p>

<p>If you have been working in the software development/computer admin work, you probably been doing searches for some obscure libraries that named after the coders or character names in animes.</p>

				<content:encoded><![CDATA[<p>Well, first of all, I am not a fan of Windows nor Linux and Mac. I use Windows and Linux at work and at home, so hopefully my comment is not biased.</p>
<p>Today, I upgraded my Ubuntu distro from 10.04 to 10.10 at home, and decided to setup the chat accounts from the top right menu. Setting up the chat and social accounts are pretty straight-forward. The idea is great, manage all the accounts in a single menu, from that menu you can set the status (&#8220;Online, &#8220;Away&#8221;, &#8220;Offline&#8221; etc) by one click. So I clicked on &#8220;Offline&#8221;, Okay, it worked&#8230; but how do I re-able to online status? The menu just grayed out, and nothing you can click on. WTF!! Come on, Ubuntu&#8230; or even Linux, could you please release a single distro this is truly user friendly and stop making its users wished they were using Windows?</p>
