		<h2>Starting using octopress.</h2>

<p>I&#8217;v decided to try using octopress in favor of wordpress. I&rsquo;m hoping this will go better than my attempt to use <a href="https://ghost.org">Ghost</a> .</p>

<p>One of the biggest best features of Wordpress is the Media Library. And without Wordpress backing this blog I have to figure out a good workflow for adding images to my blog. I&rsquo;m thinking that using S3-style buckets tied in to our <a href="http://ceph.com">Ceph</a> deployment at work. But this is not currently up and running so in the mean time i just have to use dropbox or add a custom rsync to octopress to push images as well as the blog.</p>

	<div class="entry-content" itemprop="articleBody">
		<h2>Installing Dnsmasq</h2>

<figure class='code'><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
</pre></td><td class='code'><pre><code class='bash'><span class='line'>    brew up <span class="o">&amp;&amp;</span> brew install dnsmasq
</span></code></pre></td></tr></table></div></figure>


<p>The installation process will output several commands that you can use to start Dnsmasq automatically with a default configuration. I used the following commands but you should use whichever commands brew tells you to:</p>

<h2>Configuring Dnsmasq</h2>

<p>Now that you have Dnsmasq installed and running, it’s time to configure it! The configuration file lives at <code>/usr/local/etc/dnsmasq.conf</code> by default, so open this file in your favourite editor.</p>

<p>One the many, many things that Dnsmasq can do is compare DNS requests against a database of patterns and use these to determine the correct response. I use this functionality to match any request which ends in .dev and send <code>10.200.200.10</code> in response. The Dnsmasq configuration directive to do this is very simple:</p>

<figure class='code'><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
</pre></td><td class='code'><pre><code class='bash'><span class='line'>    <span class="nv">address</span><span class="o">=</span>/dev/10.200.200.10
</span></code></pre></td></tr></table></div></figure>


<p>Insert this into your <code>/usr/local/etc/dnsmasq.conf</code> file (I put it near the example <code>address=/double-click.net/127.0.0.1</code> entry just to keep them all together) and save the file.</p>

<p>You may need to restart Dnsmasq to get it to recognise this change. Restarting Dnsmasq is the same as any other service running under <code>launchd</code>:</p>

<figure class='code'><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
<span class='line-number'>2</span>
</pre></td><td class='code'><pre><code class='bash'><span class='line'>    sudo launchctl stop homebrew.mxcl.dnsmasq
</span><span class='line'>    sudo launchctl start homebrew.mxcl.dnsmasq
</span></code></pre></td></tr></table></div></figure>


<p>You can test Dnsmasq by sending it a DNS query using the <code>dig</code> utility. Pick a name ending in <code>dev</code> and use dig to query your new DNS server:</p>

<figure class='code'><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
</pre></td><td class='code'><pre><code class='bash'><span class='line'>    dig local.site.dev @127.0.0.1
</span></code></pre></td></tr></table></div></figure>


<p>You should get back a response something like:</p>

<figure class='code'><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
<span class='line-number'>2</span>
</pre></td><td class='code'><pre><code class='bash'><span class='line'>    <span class="p">;;</span> ANSWER SECTION:
</span><span class='line'>    local.site.dev. <span class="m">0</span> IN    A   10.200.200.10
</span></code></pre></td></tr></table></div></figure>


<h2>Configuring OS X</h2>

<figure class='code'><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
<span class='line-number'>2</span>
<span class='line-number'>3</span>
<span class='line-number'>4</span>
<span class='line-number'>5</span>
</pre></td><td class='code'><pre><code class='bash'><span class='line'>    sudo mkdir -p /etc/resolver
</span><span class='line'>    <span class="c"># Create file for domain .dev</span>
</span><span class='line'>    sudo tee /etc/resolver/dev &gt;/dev/null <span class="s">&lt;&lt;EOF</span>

	<div class="entry-content" itemprop="articleBody">
		<p>A while ago I bought a Raspberry Pi (model B) planning to build an Entertainmentsystem. The main reason for this was that I had gotten tired on using My TVs builtin player that did not support any of the format I wanted to use.</p>

<p>After looking around on the alternatives I decided there where three ways to go.</p>

<ol>
<li>Raspbmc</li>
<li>OpenELEC</li>
<li>Build it myself.</li>
</ol>


<p>As building it myself would take me to much time. I opted for either alternative 1 or 2. After looking at some vs writeups and youtube reviews it seamed to me that rasbmc was the faster of the two (less sluggish in menus and such).</p>

<p>Installing rasbmc was a breeze so I will not cover it, have a peek over at the official <a href="http://www.raspbmc.com/">www.raspbmc.com</a>.</p>

		<p>After looking at a D-link NAS that I borrowed from a friend I decided that i should buy a real NAS.</p>

<p>I Finally settled on the Synology Diskstation DS214<a href="http://simon.ispy.se/blog/wp-content/uploads/2014/01/DS214.jpg"><img src="http://simon.ispy.se/blog/wp-content/uploads/2014/01/DS214.jpg" alt="DS214" /></a></p>

<p>I&#8217;v gone through the checklist, migrating all unarranged photos (from 4 different iphoto-libraries, and my very old photos from pre 2008 ) into the NAS.</p>
