After some hours research I decided to go for the <a href="http://www.rackspacecloud.com">Rackspace cloud</a>. I chose the minimal setup to start with, which is a 256MB memory configuration that comes with 10GB disk space. As stated in the specs, the 256MB plan will get you 1/64 of the CPU allocation. Which is fine to start with for a standard LAMP setup.</p>
<p>For now they only offer a large variety of Linux distributions. I chose Debian 5.0 Lenny, because it makes migration easier as the site is running on Debian 5.0 already. The registration process and setup of the minimal Debian install went very smoothly. In under two hours I had successfully migrated a website. So for the setup part I am totally satisfied, let&#8217;s see how the availability part will develop.</p>

			<content:encoded><![CDATA[<p>In order to know what kind of resources a new application needed I figured out to do a load test. The load testing software I used for this test is <a href="http://jakarta.apache.org/jmeter/">Apache Jmeter</a>. The application to test is a Java based application deployed in Tomcat 6.</p>
<p>I used the Jmeter HTTP Proxy Recorder to simulate a normal user session to create a realistic test plan. Once I executed the test plan against the web application it returned Internal Server Error (Response code: 500). By using the &#8220;View Results Tree&#8221; Listener I was able to locate the problem as the Listener displays basic HTML and XML representations of the response. </p>
<div class="codesnip-container" >
<div class="text codesnip" style="font-family:monospace;">javax.faces.application.ViewExpiredException: viewId:/presentation/task.jsf - View /presentation/task.jsf could not be restored.</div>
</div>
<p>It appeared that the HTTP Proxy Recorder had recorded the server and client state. The <em>javax.faces.ViewState</em> field is written for both server and client side state saving. So removing this attribute from the sampler data makes Jmeter process the pages without error.</p>
<p>It took me a couple of hours to resolve this issue, hope this helps someone stumbling across the same.</p>

			<content:encoded><![CDATA[<p>Today I switched from the Code Markup to the <a href="http://wordpress.org/extend/plugins/codesnippet-20/">Code Snippet</a> WordPress plugin. Therefore I had to change the way the code block is activated. This is a time consuming job if you have to do this by hand, so I figured out there should be a smarter way of doing this. Check out the MySQL replace function below:</p>
<div class="codesnip-container" >
<div class="text codesnip" style="font-family:monospace;">update [table_name] set [field_name] = replace([field_name],&#8217;[string_to_find]&#8216;,&#8217;[string_to_replace]&#8216;);</div>
</div>
<p>And so the above translated to the lines I needed:</p>
<div class="codesnip-container" >
<div class="text codesnip" style="font-family:monospace;">mysql&gt; update wp_vleeuwen_posts set post_content = replace(post_content, &#8216;&lt;pre&gt;&lt;code&gt;&#8217;, &#8216;[code lang=&quot;text&quot;]&#8216;);<br />
Query OK, 35 rows affected (0.06 sec)<br />
Rows matched: 72 &nbsp;Changed: 35 &nbsp;Warnings: 0</p>
<p>mysql&gt; update wp_vleeuwen_posts set post_content = replace(post_content, &#8216;&lt;/code&gt;&lt;/pre&gt;&#8217;, &#8216;[/ code]&#8216;);<br />
Query OK, 35 rows affected (0.01 sec)<br />
Rows matched: 72 &nbsp;Changed: 35 &nbsp;Warnings: 0</p>
<p>mysql&gt;</p></div>
</div>
<p>Notice the little typo I had to make in order to let the above code snippet work ([/ code]).</p>

But lately I missed some functions like viewing HTML formatted mail, auto address completion and LDAP address book functionality. So I started to look for a webmail client that comes with this functionality build-in and came up with this nice AJAX based webmail solution for IMAP servers, called <a href="http://roundcube.net/">RoundCube</a>.</p>
<p>The fact that RC will be in the next Debian stable release (squeeze) was the final straw. Using the Lenny backports repo you can install RC on Lenny (current stable). See the following steps below: </p>
<p><strong>1. Create to following file if it not exists:</strong></p>
<div class="codesnip-container" >
<div class="text codesnip" style="font-family:monospace;"># vi /etc/apt/preferences</div>
</div>
<p><strong>2. Add the following lines:</strong></p>
<div class="codesnip-container" >
<div class="text codesnip" style="font-family:monospace;">Package: *<br />
Pin: release a=stable<br />
Pin-Priority: 600</p>
<p>Package: roundcube roundcube-core roundcube-mysql<br />
Pin: release a=lenny-backports<br />
Pin-Priority: 999</div>
</div>
<p>There is also a postgresql and sqlite database meta-package available.</p>
<p><strong>3. Edit /etc/apt/sources.list and add the following lines:</strong></p>
<div class="codesnip-container" >
<div class="text codesnip" style="font-family:monospace;"># Testing (squeeze) for gallery2<br />
deb http://ftp.us.debian.org/debian/ squeeze main contrib non-free<br />
deb-src http://ftp.us.debian.org/debian/ squeeze main contrib non-free</div>
</div>
<p><strong>4. Update the apt database and upgrade the gallery2 package:</strong></p>
<div class="codesnip-container" >
<div class="text codesnip" style="font-family:monospace;"># apt-get update<br />
# apt-get install roundcube</div>
</div>
<p>Next thing is to walk through the main.inc.php config file located in &#8216;/etc/roundcube&#8217; and the Apache configuration.</p>
<p>Restart apache and navigate to your RoundCube url and off you go.</p>
<p>I have been test driving RoundCube for about a month and can conclude that RoundCube is here to stay!</p>

			<content:encoded><![CDATA[<p>It took me some time to figure out how to get the wireless device of my Amilo Li 2727 working with Windows 7. For the ones who stumble across the same problem I have describe how to solve it.</p>
<ol>
<li>Download the Windows XP Drivers For Amilo Li 2727 <a href="http://rapidshare.com/files/117455169/FSC_Amilo_Li2727_Win_XP_drivers_by_amater.rar.html">here</a></li>
<li>Extract the contents of the compressed file</li>
<li>Open &#8216;Control Panel&#8217;, click on &#8216;System&#8217; and choose &#8216;Device Manager&#8217;</li>
<li>Open the &#8216;Action&#8217; menu item and click on &#8216;Add legacy hardware&#8217;</li>
<li>Next -> Next -> Next and pick &#8216;Network Adapters&#8217;</li>
<li>Choose &#8216;Have disk&#8217; and Navigate into the &#8216;04 WLAN&#8217; directory</li>
<li>Select &#8216;Atheros AR5007EG Wireless Network Adapter&#8217;</li>
<li>Install the FSC Launchmanager from the &#8216;05 FSC_LaunchManager&#8217; directory by executing the setup.exe</li>
<li>Reboot</li>
</ol>
<p>Once you have rebooted you should have a working wireless device. To active the wireless device, you need to press the Fn+F1 button combination and choose WLAN. I can confirm this driver works on Windows 7.</p>
<p>Good luck!</p>
<p></p>

If you also received an Intermediate Certificate then you have to concatenate this with the Domain Certificate and your Private Key file into one single .pem file. Make sure all the information is included, without any spaces or blanks, see below.</p>

			<content:encoded><![CDATA[<p>This website was served by an old timer PC running on an Intel N440BX Server Board codename Nightshade. Despite being a rock solid system, it housed a dual Intel Pentium III 600Mhz processor configuration which did not meet today&#8217;s performance demands and energy consumption.<br />
So I decided to build a new computer system that was a little bit faster and more energy efficient than it&#8217;s predecessor and thus environmentally friendly.</p>
<p>After doing some research I decided to go for the following setup:</p>
<ul>
<li>Antec NSK3480 MicroTower, EarthWatts 380 Watt PSU</li>
<li>Intel Desktop board D945GCLF2, Atom 330</li>
<li>Kingston ValueRam 2GB DDR2 533MHz C4</li>
<li>2 Western Digital AV-GP Green 1TB, 5400~7200rpm, 8MB, SATA2</li>
<li>2 Serial ATA II Cable, 0.75m</li>
<li>Scythe Mini Kaze Ultra 40mm x 20mm</li>
</ul>
<p>The Antec casing comes with an energy efficient PSU. It&#8217;s <a href="http://www.80plus.org/">80 PLUS®</a> certified and is equipped with a built-in active PFC to make the PSU reduce electrical waste and protect the environment.</p>
<p>As some reviews at <a href="http://www.silentpcreview.com/forums/viewtopic.php?t=50388">silentpcreview.com</a> stated, the stock cooler on the chipset is not that quite as you would expect. I decided to replace the 40mm x 10mm stock cooler with the Scythe Mini Kaze Ultra 40mm x 20mm. Because the motherboard sits inside a MicroTower there was space enough to put the Mini Kaze Ultra on top of the heatsink as you can see on the pictures below.</p>
<p><a href='http://www.vleeuwen.net/wp-content/uploads/2009/10/minikazeultra.jpg' rel="lightbox[CoolerMod]"><img src="http://www.vleeuwen.net/wp-content/uploads/2009/10/minikazeultra-150x150.jpg" alt="" title="Mini Kaze Ultra" width="150" height="150" class="alignnone size-thumbnail wp-image-86" /></a> <a href='http://www.vleeuwen.net/wp-content/uploads/2009/10/minikazaultraonheatsink.jpg' rel="lightbox[CoolerMod]"><img src="http://www.vleeuwen.net/wp-content/uploads/2009/10/minikazaultraonheatsink-150x150.jpg" alt="" title="Mini Kaza Ultra on heatsink" width="150" height="150" class="alignnone size-thumbnail wp-image-85" /></a> <a href='http://www.vleeuwen.net/wp-content/uploads/2009/10/ultraonheatsinkonmobo.jpg' rel="lightbox[CoolerMod]"><img src="http://www.vleeuwen.net/wp-content/uploads/2009/10/ultraonheatsinkonmobo-150x150.jpg" alt="" title="Ultra on heatsink on mobo" width="150" height="150" class="alignnone size-thumbnail wp-image-87" /></a></p>
<p>As expected there&#8217;s nearly no noise coming from the system. The case itself is designed to do noise cancellation with it&#8217;s dual chamber structure, and the new cooler only whispers silently. Besides doing a nice quite job it also makes a difference at it&#8217;s cooling task. That&#8217;s because it&#8217;s 10mm higher then the stock cooler.</p>
<p>Temperatures with the stock cooler:</p>
<ol>
<li>Chip Temp:   +33.0°C</li>
<li>CPU Temp:    +43.0°C</li>
<li>Sys Temp:    +38.0°C</li>
</ol>
<p>Temperatures with the Scythe Mini Kaze Ultra cooler:</p>
<ol>
<li>Chip Temp:   +31.0°C</li>
<li>CPU Temp:    +41.0°C</li>
<li>Sys Temp:    +36.0°C</li>
</ol>
<p>I&#8217;ve planned to do an energy consumption test in the coming days.</p>

If you click on Add an image, a new window appears where you should have the option buttons &#8220;Browse&#8221; and &#8220;Upload&#8221;, but they&#8217;re gone. What&#8217;s left is a &#8220;Choose files to upload&#8221; button that won&#8217;t do anything.</p>
<p>I have experienced this problem when using Mozilla Firefox 3.0.14 on Linux with the Shockwave Flash add-on enabled.</p>
<p><strong>Workaround</strong>: When this add-on is disabled the add media problem will not occur. To disable the add-on, open Firefox and go to &#8216;Tools&#8217; -> &#8216;Add-ons&#8217; and select disable Shockwave Flash.</p>

			<content:encoded><![CDATA[<p>Last weekend I installed the upgraded version of Leopard on my Mac mini. The installation went successfully but took a long time to complete. At first nothing seemed to be broken, but soon I discovered the loss of my NFS shares. So I started to look for the Directory Utility, because that was the tool I used for auto mounting my NFS shares in Leopard. After a little digging, I found out that I needed to re-add them using Disk Utility.</p>
<p>- Inside Disk Utility, click File then NFS Mounts..</p>
<p>So if you&#8217;re looking for your lost NFS shares you now know what to do.</p>
