			<content:encoded><![CDATA[<p>I would really like to know what the designers at Creative Labs have in mind when they design sound cards. Their cards seem to be broken by design. The Live card was bad enough with its random collection of DACs and DPS&#8217;s, but the Audigy 2 ZS seems no better. Aside from the fact that it&#8217;s advertised as 96 kHz and 24 bit, which it isn&#8217;t, it has serious design issues. I had some sound anomalies, so I decided to measure and test. I found:</p>
<ul>
<li>The output for LFE and center actually should output LFE and center on separate channels, but it outputs them mono, in the center channel&#8230; This makes it impossible to connect to an external amplifier and have it apply the proper 10 dB boost on the LFE signal.</li>
<li>The LFE and Center channel distort at maximum gain (or minimum attenuation: 0 dB), which is easily heard by sine testing. I had to reduce all channels by 3.2 dB to avoid distortion.</li>
<li>The center and LFE channels are 6 dB quiter than the other channels when they&#8217;re all the same in the mixer. With a test tone, all channels measured 0.78V, while LFE or center measured 0.39V. That is, LFE measured 0, center measured 0.39V with both center and LFE signal.</li>
<li>The LFE/center output has a significantly louder noise floor than the other channels.</li>
</ul>
<p>Really, what monkey designs this?</p>

<p>The world being distracted by the Boston bombing, the bill passed the U.S. house of representatives on April the 18th. It&#8217;s not signed into law yet, however.</p>

			<content:encoded><![CDATA[<p>When you want to use your IMAP account as authentication for Postfix, you can set the SASL mechanism to &#8220;rimap&#8221;. However, by default, it will not supply the realm (domain) and therefore will authenticate with an incomplete username (john instead of john@bla.com).</p>
<p>To fix that, you need to add &#8220;-r&#8221; to the options in /etc/default/saslauthd (in Debian based distro&#8217;s):</p>
<p><pre class="php">OPTIONS=<span style="color: #ff0000;">&quot;-r -c -m /var/run/saslauthd&quot;</span></pre></p>

			<content:encoded><![CDATA[<p>A reminder which printer type I have to select when I reinstall my mom&#8217;s Officejet in Linux: “HP Officejet 6600 E-all-in-one Printer &#8211; h711a”.</p>
<p>At the time of installation, last week, the printer wasn&#8217;t supported by the version of hplip that&#8217;s shipped with Mint Linux 13 (Maya), so I had to <a href="http://hplipopensource.com/hplip-web/downloads.html">download</a> a newer version. This probably won&#8217;t be an issue with the next reinstall, which hopefully won&#8217;t be soon; gladly, release 13 is an LTS. </p>

			<content:encoded><![CDATA[<p>Some time ago, the Firefox developers decided it was a good idea to trim the http(s):// from the address in the address bar. Since then, I&#8217;ve been getting HTTPS site where I don&#8217;t want it, because I can&#8217;t see what I&#8217;m doing. Especially so because HTTPS has no concept of virtual host names, and putting https:// in front of any domain might put you on a completely different web site. So, when I accidentally typed https:// in front of an URL once, it will remember that, but not show me&#8230; </p>
<p>Luckily it can be disabled, by setting browser.urlbar.trimURLs to false in about:config.</p>
<p>This annoying feature is right up there with the removal of the RSS icon from the address bar.</p>

<p>It has a metal frame that fits my cross-over front panel, and the metal frame is shiny silver. And, the screw holes aren&#8217;t grounded.</p>

		<description><![CDATA[]]></description>
			<content:encoded><![CDATA[<p>I wanted to change the text of visited links on payformystay.com, using CSS. In the offer summary, I wanted to change the link text &#8220;Check it out!&#8221; with &#8220;Check it out again!&#8221; after the user had indeed checked out the offer.</p>
<div id="attachment_2386" class="wp-caption alignnone" style="width: 834px"><a href="http://blog.bigsmoke.us/uploads/2013/01/payformystay-offer.png"><img src="http://blog.bigsmoke.us/uploads/2013/01/payformystay-offer.png" alt="A payformystay.com offer" title="A payformystay.com offer" width="824" height="232" class="size-full wp-image-2386" /></a><p class="wp-caption-text">An example of a payformystay.com offer where I'd want to replace the 'Check it out!' link text.</p></div>
<p>I thought I could use something as simple as:<br />
<pre class="php">&lt;a href=<span style="color: #ff0000;">&quot;/offer/34234-title&quot;</span>&gt;
  &lt;span <span style="color: #000000; font-weight: bold;">class</span>=<span style="color: #ff0000;">&quot;unvisited-label&quot;</span>&gt;Check it out!&lt;/span&gt;
  &lt;span <span style="color: #000000; font-weight: bold;">class</span>=<span style="color: #ff0000;">&quot;visited-label&quot;</span>&gt;Check it out again!&lt;/span&gt;
&lt;/a&gt;</pre></p>
<p>together with&#8230;</p>
<p><pre class="css">a<span style="color: #3333ff;">:link </span>span.visited-label,
a<span style="color: #3333ff;">:visited </span>span<span style="color: #6666ff;">.unvisited-label </span><span style="color: #66cc66;">&#123;</span>
  <span style="color: #000000; font-weight: bold;">display</span>: <span style="color: #993333;">none</span>;
<span style="color: #66cc66;">&#125;</span>
&nbsp;
a<span style="color: #3333ff;">:link </span>span.unvisited-label,
a<span style="color: #3333ff;">:visited </span>span<span style="color: #6666ff;">.visited-label </span><span style="color: #66cc66;">&#123;</span>
  <span style="color: #000000; font-weight: bold;">display</span>: <span style="color: #993333;">inline</span>;
<span style="color: #66cc66;">&#125;</span></pre></p>
<p>Or, even simpler:<br />
<pre class="css">a<span style="color: #3333ff;">:visited </span><span style="color: #66cc66;">&#123;</span>
  <span style="color: #000000; font-weight: bold;">content</span>: <span style="color: #ff0000;">'Check it out again!'</span>;
<span style="color: #66cc66;">&#125;</span></pre></p>
<p>However, I bumped into a glass wall while trying to get this to work. Apparently, browser manufacturers have been removing features to increase security. The problem, apparently, is that as a third party you could <a href="http://yro.slashdot.org/story/09/07/02/1317205/Your-Browser-History-Is-Showing">find out</a> if somebody has been visiting a particular URL by linking to, styling <tt>:visited</tt> links and then querying the computed styles of the link. To avoid this, <tt>getComputedStyle()</tt> in the major browsers <a href="https://developer.mozilla.org/en-US/docs/CSS/:visited">now lies and most style rules are ignored</a> within rules applied to the <tt>:visited</tt> pseudo-class.</p>
<p>I&#8217;m still considering a work-around with JavaScript (setting a visited class) on the anchors, because I hate to let a good darling die.</p>
